Description

The present invention relates to a hand-carrying tool. More specifically, the present invention relates to a hand-carrying tool suitable for carrying a packaging container used for providing, for example, lunch boxes, prepared foods, soups, cakes, and sweets.

As a bag for carrying a useless packaging container made of polyethylene, for example, which is packed with lunch boxes, side dishes, soups, cakes, sweets, etc., it is also called a U bag because of its shape, and a plastic shopping bag or convenience bag depending on the usage situation. Is often used.

In the case of the combination of the above packaging container and the carrying bag, it is very difficult to maintain the horizontal posture in the bag of the container housed in the bag when carrying.

The cause is that the lower end of the conventional carrying bag has a heat fusion sealing part where the side walls are bound to each other, and the heat at the lower end is related to the direction of action of the tensile force between the handle and the heat fusion sealing part at the lower end. The side walls are easily closed by breaking at the fusion splicing portion, and there is a strong tendency for the bottom to be bent and folded. And since the bottom of the bag tends to bend and fold in this way, the fitting range between the size of the bag and the size of the container for maintaining the horizontal posture of the container inside the bag, in other words, the combination. The preferred range of is limited and narrow. Nevertheless, conventional handbags have the width of the bag defined by the width (length) of the heat-sealing sealing part at the lower end and the waist circumference (waist circumference) of the bag including the gusset (also called gusset). The size is fixed to a specific design value for each bag, and the combination of bag size and container size is often outside the preferred range for maintaining a horizontal position. If the combination of the bag and the container deviates from the preferable range even a little, the container may move the center of gravity due to vibration during walking, or an external force such as the carrier's foot hitting the container from the outside of the bag may be applied to the container. There is a problem that the container easily tilts greatly in the bag, and finally the container is in a vertical position in the bag so that one side of the container is aligned with the heat fusion sealing line at the bottom of the bag. It was.

In this way, coupled with the fact that the heat-sealing sealing part where the side walls are bound to each other is at the lower end, when used in combination with a carrying bag and a container that are not within the suitable range, the container inside the bag. Is tilted, and the contents of the container are biased, which spoils the aesthetic appearance of the serving, mixes different dishes, and causes inconveniences such as leakage of liquid contents such as sauce, which is convenient. There is a problem that it is not very comfortable.

In order to solve the above-mentioned problems, the following mechanism for maintaining the horizontal posture of the container contained in the bag has been proposed.

Specifically, as shown in FIG. 18, the plastic shopping bag of Patent Document 1 is provided with horizontal holes 101 at the four corners of the bottom portion when the container 102 is housed in the bag, and the container is contained in the plastic shopping bag. When the 102 is housed, the four corners of the container 102 are fitted into the horizontal holes 101 and held.

Further, as shown in FIG. 19, the plastic shopping bag of Patent Document 2 is provided with a cut 102 at the position of the edge of the container on the peripheral wall (side wall) 101 when the container is housed in the bag, and is provided in the plastic shopping bag. When the container is housed, the edge of the container is caught by the cut 102 and held.

Utility model registration No. 3146353 JP-A-2010-285170

However, since the mechanism for maintaining the horizontal posture of Patent Document 1 is based on the premise that the four corners of the container are fitted into the four horizontal holes provided in the bag, the size and shape of the container to be stored in the bag can be varied. There is a problem that it lacks the corresponding versatility, and it is necessary to prepare a dedicated plastic shopping bag for each container size and shape, that is, a large number of types of bags having different dimensions.

Further, in the mechanism for maintaining the horizontal posture of Patent Document 2, a considerable number of cuts must be provided in the plastic shopping bag in order to ensure versatility corresponding to the variation in the size of the container to be stored in the bag. There is a trade-off between securing the tensile strength of the plastic shopping bag and ensuring versatility corresponding to variations in the size of the container, and there is a problem that the tensile strength decreases when trying to increase the versatility. Furthermore, if a cut for hooking the edge of the container is provided on the peripheral wall (side wall) of the bag to receive the load of the container, it is inevitable that the bag will be easily torn from the cut. There is a problem that the tensile strength is lowered if even one cut is provided in the bag. Further, there is a problem that the cut of the plastic shopping bag may not function at all depending on the shape of the container such as no edge.

Therefore, according to the present invention, it is possible to maintain a horizontal posture when carrying the contained object, improve convenience and comfort, secure tensile strength as a hand-carrying tool, and further, the contained object. It is an object of the present invention to provide a highly versatile hand-carrying tool capable of flexibly responding to variations in size and shape and maintaining a horizontal posture of the contained object regardless of the size and shape of the contained object.

In order to achieve such an object, the hand-carrying tool of the present invention is connected to the facing side wall portions and the lower ends of each of the facing side wall portions, and is sandwiched and expanded by the facing side wall portions in a folded state. A gusset portion that constitutes the bottom, a pair of handle portions that extend from the upper ends of the opposite side wall portions in a direction orthogonal to the direction X of the mountain fold ridge line of the gusset portion, and a mountain of the gusset portion of the opposite side wall portions. It has a side wall-gusset sealing portion that seals both ends in the direction X below the folded ridge line. The "side wall-gusset sealing" is used to represent an embodiment in which the side wall portion and the gusset portion are sealed.

Therefore, according to this hand-carrying tool, since there is no sealing wire / sealing portion at the bottom of the state where the object is housed inside, the object housed inside is affected by the presence of the sealing wire / sealing part. Never. In addition, since there is no sealing line / sealing part on the bottom and the shape when the object is stored inside is not affected by the dimensions of the sealing line / sealing part on the bottom, the object housed inside. It can be accommodated according to the size and shape of the container, and the horizontal posture of the object to be carried with respect to the carrying tool can be maintained and various sizes and shapes can be accommodated.

Moreover, since no cut is provided in the peripheral wall (side wall), the strength as a hand-carrying tool is not impaired, and the horizontal posture holding function of the contained object is exhibited regardless of the shape of the contained object. To.

Further, in the hand-carrying tool of the present invention, the side wall portion and the corner portion of the gusset portion may be cut along the side wall-gusset sealing portion. In this case, the amount of material used is saved when the raw material of the hand-carrying tool is reusable (that is, the material cut at the time of manufacture is not contaminated and is clean by collecting it immediately after cutting. Since it can be recovered in the state and can be reused as it is, the amount of material used is saved). In addition, when the raw material of the hand-carrying tool is a predetermined recycled resource, it is calculated by multiplying the re-commercialization implementation consignment fee (that is, the re-commercialization obligation amount that a specific business operator must re-commercialize by the implementation consignment unit price). Things: The Act on Promotion of Separate Collection and Recycling of Containers and Packaging (Act No. 112 of June 16, 1995) will be saved. In this case, depending on the form of the hand-carrying tool, a dent (or pocket) is formed by the side wall portion and the gusset portion, and the dent is easily caught by, for example, a door lever, a bicycle handlebar, or a brake lever. Is not formed. In this case, further, when used as a hand-carrying tool, on each of the total four sides of the three side surfaces and one bottom surface, or on each of the five sides of the four side surfaces and one bottom surface, and at the center position of each surface (each). A pattern can be added by printing only one side of the tubular raw material (including a mode that covers the entire surface and a mode that is continuous across four or five sides).

Further, in the hand-carrying tool of the present invention, the relationship of 2 Lg ≧ Lb is established between the folded length Lg of the gusset portion in the folded state and the length Lb between the side walls at both ends and the gusset sealing portion. Is also good. In this case, the direction X of the mountain fold ridgeline of the gusset portion and the longitudinal direction of the accommodation space when the hand-carrying tool is used are orthogonal to each other. Then, when an appropriate binding force is exerted and a plurality of containers or the like are stacked in the accommodation space, these containers or the like are firmly held and the load collapse is prevented.

Further, the hand-carrying tool of the present invention further has a side wall sealing portion for sealing both ends in the direction X of the portion above the mountain fold ridge line of the gusset portion of the facing side wall portions, and is in a folded state. The relationship of 4 Lg ≧ L'may be established between the folded length Lg of the gusset portion and the length L'between the side wall sealing portions at both ends. In this case, the direction X of the mountain fold ridgeline of the gusset portion and the longitudinal direction of the accommodation space when the hand-carrying tool is used are orthogonal to each other. Then, when an appropriate binding force is exerted and a plurality of containers or the like are stacked in the accommodation space, these containers or the like are firmly held and the load collapse is prevented.

Further, in the hand-carrying tool of the present invention, the handle portion may be provided with a single through hole or a plurality of through holes in a direction orthogonal to the direction X of the mountain fold ridge line of the gusset portion. In this case, the handle portion is likely to be folded back.

Further, the hand-carrying tool of the present invention has a side wall portion facing each other, a gusset portion connected to each of the facing side wall portions, and a side wall-gusset sealing portion at a portion where the facing side wall portion and the gusset portion overlap. However, the side wall portion and the corner portion of the gusset portion are cut along the side wall-gusset sealing portion.

Therefore, according to this hand-carrying tool, the amount of material used is saved when the raw material of the hand-carrying tool is reusable (that is, the material cut at the time of manufacture is contaminated by collecting it immediately after cutting. Since it can be collected in a clean state and can be reused as it is, the amount of material used is saved). In addition, when the raw material of the hand-carrying tool is a predetermined recycled resource, it is calculated by multiplying the re-commercialization implementation consignment fee (that is, the re-commercialization obligation amount that a specific business operator must re-commercialize by the implementation consignment unit price). Things: The Act on Promotion of Separate Collection and Recycling of Containers and Packaging (Act No. 112 of June 16, 1995) will be saved. According to this hand-carrying tool, and depending on the form of the hand-carrying tool, a dent (or pocket) is formed by the side wall portion and the gusset portion, and the dent is easily caught by, for example, a door lever, a handlebar / brake lever of a bicycle, or the like. It is configured so that no dent is formed.

According to the hand-carrying tool of the present invention, the object housed inside is not affected by the presence of the sealing wire / sealing portion, and the horizontal posture of the container with respect to the hand-carrying tool at the time of carrying is maintained. It is possible to prevent the contents from being in a vertical position by hitting one side of a relatively thin rectangular parallelepiped shape against the sealing line / sealing part like a bento container, which is convenient.・ It is possible to improve comfort. In addition, since it can be used in various sizes and shapes, it is possible to improve versatility. Moreover, since the peripheral wall (side wall) is not provided with a cut and the strength is not impaired, it is possible to secure sufficient strength as a hand-carrying tool. Furthermore, since the horizontal posture holding function of the contained object can be exerted regardless of the shape of the contained object, it is possible to improve convenience, comfort, and versatility from this point as well. ..

Further, the hand-carrying tool of the present invention is a material when the raw material of the hand-carrying tool is recyclable when the side wall portion and the corner portion of the gusset portion are cut along the side wall-gusset sealing portion. It is possible to save the amount of use, and when the raw material of the hand-carrying tool is a predetermined recycled resource, it is possible to save the implementation consignment fee for recycling, so that it is possible to suppress the discharge of waste. At the same time, resources can be effectively used, and the overall cost of manufacturing and using hand-held tools can be reduced. In this case, it is also possible to form a configuration in which a dent is not formed by the side wall portion and the gusset portion, and the dent does not get caught in a protrusion or the like during use of the hand-carrying tool, so that convenience and safety are improved. It becomes possible to plan.

The hand-carrying tool 10 is connected to the opposite side wall portions 2 and 2 and the lower ends of each of the facing side wall portions 2 and 2, and is sandwiched between the opposite side wall portions 2 and 2 in a folded state. A pair of gusseted portions 1 forming the bottom portion of the hand-carrying tool 10 and a pair extending in a direction orthogonal to the direction X of the mountain fold ridge line 1a of the gusseted portion 1 from the upper ends of each of the side wall portions 2 and 2 facing each other. The handle portions 3 and 3 face the side wall sealing portions 2c and 2c that seal both ends of the gusset portion 1 of the opposite side wall portions 2 and 2 in the direction X above the mountain fold ridge line 1a. It has side walls-gusset sealing portions 2d and 2d that seal both ends of the gusset portion 1 of the side wall portions 2 and 2 in the direction X below the mountain fold ridge line 1a.

The material / material of the hand-carrying tool 10 is not limited to a specific material as long as it is flexible and flexible and can exhibit sufficient strength when suspending the assumed container, for example. It is appropriately selected from polyethylene, polyester, polystyrene, polypropylene, nylon, pulp, non-woven fabric, linen, cotton, silk, etc. in consideration of the usage situation and expected contents.

As shown in FIG. 1, the side wall portions 2 and 2 have an intermediate free end 2a between the two handle portions 3 and 3 at the upper ends of the side wall portions 2 and 2 and an outer side free end 2b of the handle portions 3 and 3. , 2b is closed and the hand-carrying tool 10 is folded (hereinafter, referred to as a folded state of the hand-carrying tool 10), and the front side and the back side face each other. In the drawings, the V-axis represents the vertical direction (and V _U represents the upward direction, _VL represents the downward direction), and the H-axis represents the horizontal direction, based on the usage state of the hand-carrying tool 10.

As shown in FIG. 3, the side wall portions 2 and 2 are in a state in which the middle free end 2a and the side free ends 2b and 2b are opened so that a container or the like can be put in the handbag 10 (hereinafter, the handbag 10). The side wall as the hand-carrying tool 10 is formed while facing each other in the accommodation standby state).

The gusset portion 1 is sandwiched between the side wall portions 2 and 2 (front and back surfaces) facing each other in the folded state of the hand-carrying tool 10 shown in FIG. It forms two valleys and is folded, and also constitutes the bottom of the hand-carrying tool 10 in the accommodation standby state of the hand-carrying tool 10 shown in FIG.

The gusset portion 1 and the lower end of the side wall portion 2 are connected in a direction orthogonal to the direction X of the mountain fold ridge line 1a of the gusset portion 1 sandwiched between the side wall portions 2 and 2 (hereinafter referred to as the gusset ridge line direction X). ..

Heat on both ends of the side wall portions 2 and 2 in the gusset ridge direction X on the side free ends 2b and 2b of the gusset portion 1 with respect to the material of the handbag 10, for example. By fusing, adhering, or sewing, side wall sealing portions 2c and 2c in a direction orthogonal to the gusset ridge direction X in the front view are formed. The front view direction of the side wall sealing portion 2c with respect to the gusset ridge line direction X is not limited to the direction orthogonal to the example shown in FIG. It doesn't matter if there is.

In the side wall sealing portion 2c, the side wall portions 2 and 2, that is, the side wall portions 2 on the front side and the side wall portions 2 on the back surface side are sealed with each other in FIG.

Further, the material of the hand-carrying tool 10 is formed on both sides of the side wall portions 2 and 2 and the gusset portion 1 in the gusset ridge line direction X on the opposite sides of the side free ends 2b and 2b from the mountain fold ridge line 1a of the gusset portion 1. In consideration of the above, for example, by heat fusion, bonding, or sewing, side wall-gusset sealing portions 2d and 2d in a direction intersecting the gusset ridge direction X at 45 ° in the front view are formed. The angle between the side wall and the gusset sealing portions 2d and 2d is paraphrased so that the width of the lower end is narrower than the width of the mountain fold ridge line 1a position of the gusset portion 1 of the side wall portion 2 in the front view of the hand-carrying tool 10. And, the side walls-gusset sealing portions 2d and 2d on both sides are arranged so as to form an upside-down C shape. The angle of the side wall-gusset sealing portion 2d with respect to the gusset ridge direction X in the front view is not limited to 45 ° and can be adjusted as appropriate. Specifically, for example, 30 ° to 60 °. It can be appropriately adjusted in the range of about °, and further, it may be 90 ° (that is, in the orthogonal direction).

In the side wall-gusset sealing portion 2d, one of the facing side wall portions 2 and 2 and one of the facing gusset portions 1 in the folded state of the handbag 10 are sealed. Specifically, in FIG. 1, the side wall portion 2 on the front side and the side of the gusset portion 1 connected to the side wall portion 2 on the front side are sealed, and the side wall portion 2 on the back surface side and the gusset portion 1 are sealed. The side wall portion 2 on the back surface side and the side connected to the side wall portion 2 are sealed. In addition, such a sealing method is also called a V-seal.

When the side wall-gusset sealing portion 2d is formed in a direction orthogonal to the gusset ridge direction X in the front view, the side wall portion 2 on the front side and the side wall portion on the front side of the gusset portion 1 are formed. The side connected to 2, the side wall portion 2 on the back surface side, and the side of the gusset portion 1 connected to the side wall portion 2 on the back surface side may all be sealed together. Further, the side wall-gusset sealing portion 2d may be formed so as to extend beyond the mountain fold ridge line 1a of the gusset portion 1 to the side wall portion 2, and further, the side wall-gusset sealing portion 2d and the side wall sealing portion 2c May be continuously formed as a series / integral sealing portion. Further, for example, in the example shown in FIG. 1, the side wall-gusset sealing portion 2d is formed continuously and seamlessly over substantially the entire gusset portion 1, but the aspect of the side wall-gusset sealing portion 2d. Is not limited to this, and may be formed only in a part of the gusset portion 1, or may be formed intermittently as shown by a broken line.

Then, the accommodation space 5 for the hand-carrying tool 10 is formed by the bottom portion formed by the gusset portion 1 and the side wall formed by the side wall portions 2 and 2.

The handle portion 3 is from the upper ends of the opposite side wall portions 2 and 2, in other words, the side opposite to the side connected to the gusset portion 1 in the direction orthogonal to the gusset ridge direction X of each of the opposite side wall portions 2 and 2. Therefore, it is provided so as to be connected and extended in a direction orthogonal to the gusset ridge direction X.

In the handle portion 3, the portions extending from the upper ends of the side wall portions 2 and 2 facing each other are connected to each other at the upper end. As a result, the handle portion 3 is grasped and gripped to function as a handle. It should be noted that the portions extending from the upper ends of the side wall portions 2 and 2 facing each other are sealed at the upper end by, for example, heat fusion, adhesion, or sewing in consideration of the material of the hand-carrying tool 10. You may do so.

Both ends of the handle portion 3, in other words, both ends of the handle portion 3 in the gusset ridge direction X are free ends (open ends). As a result, a hole 3a into which the user's hand of the hand-carrying tool 10 is inserted is formed.

Further, the handle portions 3 are provided as a pair of handle portions 3 and 3 separated from each other in the gusset ridge line direction X. Then, according to the above configuration, the direction in which the user's hand of the hand-carrying tool 10 is inserted into the hole 3a so as to grasp the pair of handles 3 and 3 together coincides with the gusset ridge direction X. Further, the plan-viewing direction of the side wall sealing portion 2c also coincides with the direction in which the user's hand is inserted into the hole portion 3a. In this way, by matching the direction in which the user's hand is inserted into the hole 3a with the gusset ridge direction X and the plan view direction of the side wall sealing portion 2c, the facing side wall portions 2 and 2 are closed to each other. It is possible to prevent the force to act on the containment and contribute to maintaining the horizontal posture of the containment.

It should be noted that the handle portion 3 is formed as having a gusset portion that is sandwiched between portions extending from the side wall portions 2 and 2 that face each other in the folded state of the hand-carrying tool 10 to form a mountain / valley and is folded. You may. In this case, while the size of the handle portion 3 in the folded state of the hand-carrying tool 10 is suppressed, that is, it is shortened by the amount folded as the gusset portion, the height dimension of the handle portion 3 is reduced during use. Sufficiently secured.

The overall size of the hand-carrying tool 10 and the dimensions of the gusset portion 1, the side wall portion 2, and the handle portion 3 in each direction are not limited to specific sizes and values, and are not limited to specific sizes and values. It is adjusted appropriately according to the shape, size, number, etc. of

The above-mentioned hand-carrying tool 10 is manufactured by using, for example, a polyethylene tubular raw material (also referred to as a tube material).

In the method of manufacturing the hand-carrying tool 10 of the present embodiment, the gusset portion 1 is formed on the tubular raw fabric material 11 along the direction of the axial center of the cylinder, and the gusset portion 1 and the gusset portion 1 and the tubular raw fabric material are formed. When the tubular raw material 11 is folded by folding the opposite positions in the cross section perpendicular to the axis of 11, the pair of side wall sealing portions 2c and 2c in the direction orthogonal to the axial center direction are separated in the axial center direction. The side wall-gusset sealing portions 2d and 2d in the direction of inclining from the positions of the pair of side wall sealing portions 2c and 2c, respectively, toward between the side wall sealing portions 2c and 2c. It is formed so as to be separated in the axial direction, and is cut along the side wall sealing portion 2c, and further, a portion 12 including a part of the side wall sealing portion 2c is cut off and a portion 13 sandwiched between the side wall sealing portions 12 is cut off. Also, it is cut along the side wall-gusset sealing portion 2d.

Specifically, as shown in FIG. 4, first, the tubular raw material 11 is folded by forming peaks and valleys with respect to the cylinder axis so that the mountain fold ridge line 1a is in the direction of the cylinder axis. The gusset portion 1 is formed. Then, in the tubular raw fabric material 11, a mountain is inserted inside (in other words, a mountain fold ridge line 1a is inserted), the gusset portion 1 is folded, and the gusset portion 1 and the tubular raw fabric material 11 are perpendicular to the axis. The positions facing each other in the cross section are flattened while being folded along the axial direction of the cylinder.

Next, at the portion where the gusset portion 1 of the tubular raw material 11 is formed, the end portion on the mountain fold ridge line 1a side is at a predetermined interval (that is, the gusset ridge line direction X) in the tubular axis direction (that is, the gusset ridge line direction X). A pair of side walls in a direction that is at or near a position (distance of dimension L in the gusset ridge direction X of the tool 10) and is inclined so that a pair of things as a hand-held tool 10 approach each other. The gusset sealing portions 2d and 2d are formed by heat fusion.

Further, the portion of the tubular raw material 11 on which the gusset portion 1 is formed and folded and flattened, at least on the side opposite to the gusset portion 1 from the mountain fold ridge line 1a of the gusset portion 1 (in other words, the gusset portion 1). Is equal to the dimension L of the gusset ridge direction X of the hand-carrying tool 10 at a predetermined distance (that is, the center distance of the side wall sealing portion 2c) in the tubular axis direction (that is, the gusset ridge direction X). The side wall sealing portion 2c in the direction orthogonal to the cylinder axis direction is formed by heat fusion. In the example shown in FIG. 4, the sealing portion 2Co is formed over the entire width of the tubular raw material 11 (that is, the dimension in the direction orthogonal to the cylinder axis direction), and one of the sealing portions 2Co. The portion is set to be the side wall sealing portion 2c.

Here, when the tubular raw material 11 is used, the side wall sealing portion 2c and the pair of side wall-gusset sealing portions 2d and 2d as those of a certain hand-carrying tool 10 are in the cylinder axis direction (gusset ridge direction). It is formed side by side in X).

Subsequently, the tubular raw material 11 is cut at the center line of the side wall sealing portion 2c, in other words, at the center position of the side wall sealing portion 2c in a direction orthogonal to the cylinder axis direction (in FIG. 4). Cutting line 15). As a result, the original shape 11A having a dimension L in the direction of the cylinder axis (the gusset ridge direction X) is formed.

Next, a predetermined number of prototypes 11A are stacked, and cutting is performed to form the handle portion 3. Specifically, the cut-off portions at both ends of the side wall (the shaded portions with reference numerals 12 in FIG. 5) cut out by cutting are set at both ends in the cylinder axis direction (gusset ridge line direction X) of the prototype 11A. The cut-out portion 12 at both ends of the side wall may be set to a range in which a part of the side wall sealing portion 2c is left or a range in which the entire side wall is cut off, or a range not including the gusset portion 1. It may be set or may be set in a range including the gusset unit 1.

The front view shape of the side wall cutout portion 12 (that is, the shape of the shaded portion of reference numeral 12 in FIG. 5) is not limited to a specific shape as long as it includes at least the upper end corner portion of the original shape 11A. However, for example, it may be triangular or the cutting line may be arcuate.

Further, the side wall cut portion cut out by cutting (the shaded portion indicated by reference numeral 13 in FIG. 5) is located between the adjacent side wall both end cut portions 12 and 12 in the gusset ridge line direction X, and the gusset ridge line direction X of the handle portion 3. The width of is set to a predetermined size. The side wall cutout portion 13 is set in a range that does not include the gusset portion 1.

The front view shape of the side wall cutout portion 13 (that is, the shape of the shaded portion of reference numeral 13 in FIG. 5) is not limited to a specific shape as long as it includes at least the upper end of the original shape 11A. It may be semi-elliptical or semi-circular.

In this way, a pair of side wall cut-out portions 12, 12 and side wall cut-out portions 13 are set and cut out so as to be spaced apart from each other in the gusset ridge direction X, so that the cut-out portion is an open end. A pair of loop-shaped handle portions 3 having the portions 3a are formed.

Next, along the side wall-gusset sealing portion 2d, the lower end corner portions (the shaded portions marked with reference numeral 14 in FIG. 5) on both sides of the side wall portion 2 and the gusset portion 1 in the gusset ridge direction X are cut.

In the example shown in FIG. 5, the lower end corner portion 14 is cut adjacent to (in other words, in close contact with) the side wall-gusset sealing portion 2d, but the cutting position of the lower end corner portion 14 is The position is not limited to this, and an appropriate position can be appropriately selected in consideration of, for example, technical conditions and restrictions in manufacturing. Specifically, for example, the lower end corner portion 14 may be cut at a position slightly distant from the side wall-gusset sealing portion 2d, that is, leaving room outside the side wall-gusset sealing portion 2d.

Further, in the example shown in FIG. 5, the side wall-gusset sealing portion 2d is formed in an inclined linear shape, but the shape of the side wall-gusset sealing portion 2d is not limited to the linear shape. For example, an appropriate shape can be appropriately selected in consideration of technical conditions and restrictions in manufacturing. Specifically, for example, as shown in the circle with <a> in FIG. 5, the upper end portion of the inclined linear side wall-gusset sealing portion 2d is bent in the direction along the gusset ridge direction X. It may be formed so as to be 2d'.

With the above, the hand-carrying tool 10 is completed.

According to the above-mentioned manufacturing method, the hand-carrying tool 10 can be manufactured by using the tubular raw material (tube material) as it is in the tubular shape (tube). That is, it is possible to manufacture the hand-carrying tool 10 which is easy to manufacture and can exhibit a good horizontal posture holding function with respect to the contained object.

However, the above-mentioned manufacturing method / manufacturing process of the hand-carrying tool 10 is only an example, and the method for manufacturing the hand-carrying tool of the present invention is not limited to the above-mentioned one.

Specifically, for example, in the above-mentioned manufacturing method and manufacturing process, the sealing portion 2Co (side wall sealing portion 2c) and the side wall-gusset sealing portion 2d are formed by heat fusion and cut by the cutting line 15. A predetermined number of prototypes 11A are stacked to form the handle portion 3, and the side wall portion 2 and the lower end corner portion of the gusset portion 1 are cut, but the side seal (that is, the seal (sealing)) is performed. Using a processing method in which heat fusing is also performed at the same time), sealing of the side wall portion 2 (corresponding to the formation of the sealing portion 2Co (side wall sealing portion 2c)) and heat fusing (corresponding to cutting at the cutting line 15) are performed. At the same time, sealing of the side wall portion 2-gusset portion 1 (corresponding to the formation of the side wall-gusset sealing portion 2d) and thermal fusing (corresponding to cutting along the side wall-gusset sealing portion 2d) are performed at the same time. (The side seals are processed one by one). In this case as well, the cutting for forming the handle portion 3 is performed by the same cutting as in the above-mentioned manufacturing method / manufacturing process (this cutting process is performed by stacking a predetermined number of sheets).

Further, as the material / material of the hand-carrying tool 10, for example, when a non-woven fabric or the like is used, ultrasonic cut welding (also referred to as ultrasonic cut and seal) may be used, and for example, a cloth material such as polyester may be used. If it is used, sewing may be used.

When a side seal or ultrasonic cut welding is used, the fusion portion (also called an ear) formed by normal heat fusion is not formed, the amount of material used is saved, and the hand-carrying tool 10 is used. The appearance is clean and good.

Further, although the tubular raw material 11 is used in the above-mentioned manufacturing method / manufacturing process, the hand-carrying tool 10 may be manufactured using the film material.

Further, it is not essential in the present invention that the lower end corner portions 14, 14 on both sides of the side wall portion 2 and the gusset portion 1 in the gusset ridge direction X are cut. That is, even if the lower end corner portions 14 and 14 are not cut, the horizontal posture holding function of the contained object is exhibited because there is no sealing wire / sealing portion at the bottom.

By cutting the lower end corner portions 14 and 14 on both sides of the gusset ridge direction X of the side wall portion 2 and the gusset portion 1, the material is used when the raw material of the hand-carrying tool 10 is reusable. The amount can be saved (that is, polyethylene, etc. cut at the time of manufacture can be recovered in a clean state without being contaminated by collecting immediately after cutting, and can be reused as it is, so that the amount of material used can be saved. Can be done). In addition, when the raw material of the hand-carrying tool 10 is a predetermined recycled resource, it is calculated by multiplying the re-commercialization implementation consignment fee (that is, the re-commercialization obligation amount that a specific business operator must re-commercialize by the implementation consignment unit price). Things: The Act on Promotion of Separate Collection and Recycling of Containers and Packaging (Act No. 112 of June 16, 1995) can be saved. When the raw material of the hand-carrying tool 10 is recyclable, the environmental load can be further reduced in that the amount of waste discharged can be further reduced.

Specifically, the above-mentioned hand-carrying tool 10 is used as follows, for example. First, as shown in FIGS. 2 and 3, the pair of handle portions 3 and 3 are placed on the upper side, the side wall portions 2 and 2 facing each other are separated from each other, and the gusset portion 1 is expanded. As a result, the accommodation space 5 is formed so as to be surrounded mainly by the side wall portions 2 and 2 on the side and by the gusset portion 1 on the lower side.

Then, for example, a container such as a lunch box container is housed in the storage space 5 (that is, placed on the gusset portion 1). At this time, when the vertical and horizontal dimensions of the container or the like are different, it is preferable to arrange the container or the like so that the long axis direction of the plane is orthogonal to the gusset ridge direction X.

Then, in the gusset ridge direction X, the holes 3a and 3a of both the handle portions 3 and 3 are touched, and the handle portions 3 and 3 are grasped together to lift the hand-carrying tool 10. At this time, since there is no sealing wire / sealing portion on the bottom, the size / shape of the bottom surface of the hand-carrying tool 10 is automatically adjusted by the weight of the container without being affected by the sealing wire / sealing portion. The bottom surface of 10 (that is, the gusset portion 1) is in close contact with the bottom surface of the container, and the container is reliably supported and leveled. Further, the direction in which the user's hand of the hand-carrying tool 10 is inserted into the hole 3a so as to grasp the pair of handles 3 and 3 together, the gusset ridge direction X, and the plan view direction of the side wall sealing portion 2c. Are the same, so that the force of the side wall portions 2 and 2 facing each other to close each other does not act on the contained object, and the horizontal posture of the contained object is maintained.

According to the hand-held tool 10 configured as described above, there is no sealing wire / sealing portion at the bottom (that is, the gusset portion 1), and the object housed inside has the sealing wire / sealing portion. Since it is not affected, it is possible to prevent the contents from being in a vertical position by hitting one side of a relatively thin rectangular parallelepiped shape against the sealing line / sealing part like a bento container. Become. Further, according to the hand-held tool 10, there is no sealing wire / sealing portion at the bottom (gusset portion 1), and the shape when an object is housed inside affects the dimensions of the sealing wire / sealing portion at the bottom. Since it is not received, it can be accommodated according to the size and shape of the contained object, and it is possible to maintain the horizontal posture of the contained object with respect to the carrying tool when carrying it, and it is also diverse. It becomes possible to correspond to the size and shape.

According to the hand-carrying tool 10, since no cut is provided in the side wall portion 2, the strength of the hand-carrying bag is not impaired, and the horizontal posture holding function of the contained object is exhibited regardless of the shape of the contained object. It becomes possible to do.

Further, the gusset portion 1 is provided only at the bottom portion, and the side wall-gusset sealing portions 2d and 2d are formed, and both sides of the side wall portion 2 and the gusset portion 1 in the gusset ridge direction X along the side wall-gusset sealing portion 2d. According to the hand-carrying tool 10 having a structure in which the lower end corner portion (the shaded portion marked with reference numeral 14 in FIG. 5) is cut, the gusset portion 1 is simply pushed before being formed by the folding process in the manufacturing process. By printing on only one side of the tubular raw material (tube material) that has been crushed and folded so as to be double-layered, a pattern or the like can be added to the four or five sides when used as the hand-carrying tool 10. Will be possible.

Specifically, as shown in FIG. 10A, the tubular raw material 11 is simply crushed and folded so as to be doubled, and one prototype 11A (handbag tool 10) is first along the gusset ridge direction X. The side pattern 40A, the patterns 40B and 40B of the second side surface facing each other at right angles to the gusset ridge direction X, and the bottom pattern 40C can be attached by printing on only one side. After the printing process, a folding process for forming the gusset portion 1 is performed, and the sealing portion is formed, cut, cut, and the like to produce the hand-carrying tool 10 (FIG. 10B). The central positions of the patterns 40B and 40B on the second side surface and the patterns 40C on the bottom surface in FIG. 10A are folded as the mountain fold ridge line 1a of the gusset portion 1 (see FIG. 10B).

As a result, as shown in FIG. 11, only one side of the tubular raw material 11 is printed on each of the three side surfaces and one bottom surface when used as the hand-carrying tool 10 and at the center position of each surface. It becomes possible to add a pattern or the like. It should be noted that the present invention is not limited to a mode in which a pattern or the like is attached to only a part of the central position of each surface, and in addition to being able to attach a pattern or the like to a part of the central position of each surface, the center of each surface is applied. It is possible to add a pattern or the like to a part of the position deviated from the position, or to add a pattern or the like covering the entire surface of each surface, and further to add a continuous pattern or the like across all four surfaces. It is also possible. As an example, the pattern 40A on the first side surface and the patterns 40B and 40B on the second side surface all display the same logo mark (the size is different if necessary), and the pattern 40C on the bottom surface is used. It is conceivable to display the specifications of the hand-carrying tool 10 and precautions for handling.

Specifically, as shown in FIG. 12A, the tubular raw material 11 is simply crushed and folded so as to be doubled, and one prototype 11A (handbag tool 10) is attached along the gusset ridge direction X. The patterns 40A and 40A of the first side surfaces facing each other, the patterns 40B and 40B of the second side surfaces facing each other perpendicular to the gusset ridge direction X, and the patterns 40C of the bottom surface can be attached by printing on only one side. It will be possible. After the printing process, a folding process for forming the gusset portion 1 is performed, and the sealing portion is formed, cut, cut, and the like to produce the hand-carrying tool 10 (FIG. 12B). The central positions of the patterns 40B and 40B on the second side surface and the patterns 40C on the bottom surface in FIG. 12A are folded as the mountain fold ridge line 1a of the gusset portion 1 (see FIG. 12B).

As a result, as shown in FIG. 13, only one side of the tubular raw material 11 is located on each of the four side surfaces and one bottom surface when used as the hand-carrying tool 10, and at the center position of each surface. It becomes possible to add a pattern or the like by printing. It should be noted that the present invention is not limited to a mode in which a pattern or the like is attached to only a part of the central position of each surface, and in addition to being able to attach a pattern or the like to a part of the central position of each surface, the center of each surface is applied. It is also possible to add a pattern or the like to a part of the position deviated from the position, and further, it is possible to add a continuous pattern or the like over five surfaces.

In the case of the example shown in FIG. 13, therefore, by printing only one side of the tubular raw material 11, regardless of how the hand-carrying tool 10 is held, that is, no matter how the hand-carrying tool 10 is held, there are five sides. At least one of the patterns 40A, 40B, and 40C can be configured to be exposed without fail. Therefore, when a logo mark is attached as the patterns 40A, 40B, 40C, for example, the logo mark is always exposed and a high advertising effect can be exhibited.

Further, as described above, the overall size of the hand-carrying tool 10 and the dimensions of the gusset portion 1, the side wall portion 2, and the handle portion 3 in each direction can be adjusted as appropriate, but the folded length of the gusset portion 1 (in other words, the vertical direction). That is, the gusset width in the V-axis direction) and the base length (in other words, the length of the lower end between the pair of side walls and the gusset sealing portions 2d and 2d in the gusset ridge direction X) are adjusted to a specific dimensional relationship. As a result, a unique effect is exhibited.

Specifically, as shown in FIG. 14, in the front view of the hand-carrying tool 10 in a folded state, the folding length Lg in the vertical direction, that is, the V-axis direction of the gusset portion 1 and the base length Lb in the gusset ridge direction X By adjusting so as to satisfy the relationship of 2 Lg ≧ Lb, a peculiar effect of preventing the load collapse of these containers and the like when a plurality of containers and the like are stacked in the accommodation space 5 is exhibited. ..

Conventionally, the handle portion 23 has a handle portion 23 that is connected to the gusset portion 21 in which the direction of the mountain fold ridge line 21a is in the vertical direction as shown in FIG. 6, as a inverse proportion for explaining this effect, and extends upward. In the type of handbag (see below for the detailed configuration of the handbag 20 shown in FIG. 6), as shown in FIG. 15B, for example, a pet is placed on a relatively thin rectangular parallelepiped lunch container or the like in the storage space 25. When bottles and the like are stacked, the side wall portions 22 and 22 facing each other due to the slack of the gusset portion 21 when both handle portions 23 and 23 are held together and lifted together. Will be pushed out. Therefore, the binding force for suppressing rolling and slipping due to the pulling force when both handle portions 23 and 23 are closed and lifted cannot be applied to the PET bottle or the like. For this reason, the PET bottle or the like rolls or slips, moves to the end of the lunch box or the like, or falls from the upper surface of the lunch box or the like. Then, the weight of the PET bottle or the like moved to the end of the bento container or the like causes the bento container or the like to tilt, and further, the PET bottle or the like falls or slides down from the bento container or the like, and the bento container or the like is in a vertical posture. In addition, the PET bottle or the like rolls down or slides down from the upper surface of the lunch box or the like and slips into the side or the bottom of the lunch box or the like, and the side wall portions 22 and 22 of the hand-carrying tool are about to be closed with the PET bottle or the like as a fulcrum. The bento container, etc. will tilt and will be in a vertical position.

On the other hand, in the hand-carrying tool of the present invention, as shown in FIG. 15A, even when, for example, a PET bottle or the like is stacked on a relatively thin rectangular parallelepiped bento container or the like in the accommodation space 5, the container or the like is particularly provided. By arranging so that the plane long axis direction of is orthogonal to the gusset ridge line direction X, the side surface is strongly stretched by the pulling force when both handle portions 3 and 3 are grasped and lifted together, and the binding force is applied. 41 occurs. As a result, the rolling and slipping of the PET bottle and the like can be suppressed, and the inclination of the lunch box and the like can be suppressed.

It should be noted that even in the hand-carrying tool 10 adjusted so that the folded length Lg and the base length Lb of the gusset portion 1 satisfy the relationship of 2 Lg ≧ Lb as in the example shown in FIG. 14, the lower end corner portion (reference numeral in FIG. 5) is also used. Of course, the portion corresponding to the shaded portion marked with 14) may be cut.

As described above, the overall size of the hand-carrying tool 10 and the dimensions of the gusset portion 1, the side wall portion 2, and the handle portion 3 in each direction can be adjusted as appropriate, but the folded length of the gusset portion 1 (in other words, the vertical direction). That is, a unique effect is exhibited by adjusting the length between the pair of side wall sealing portions 2c and 2c in the gusset ridge direction X and the gusset width in the V-axis direction to a specific dimensional relationship.

Specifically, as shown in FIG. 16, in the front view of the hand-carrying tool 10 in a folded state, the folding length Lg of the gusset portion 1 in the vertical direction, that is, the V-axis direction, and a pair of side wall sealings in the gusset ridge direction X. By adjusting the length L'between the portions 2c and 2c so as to satisfy the relationship of 4Lg ≧ L', the load collapse of these containers, etc., especially when a plurality of containers, etc. are stacked in the accommodation space 5. (See FIG. 15A and the above description with respect to FIG. 15A). Here, the length L'between the pair of side wall sealing portions 2c and 2c is the dimension L of the gusset ridge direction X of the hand-carrying tool 10 excluding the side wall sealing portions 2c and 2c at both ends.

As in the example shown in FIG. 16, the handbag adjusted so that the folded length Lg of the gusset portion 1 and the length L'between the pair of side wall sealing portions 2c and 2c satisfy the relationship of 4 Lg ≧ L'. In the case of the tool 10, it is not necessary to adjust the folded length Lg and the base length Lb of the gusset portion 1 to a specific dimensional relationship as in the example shown in FIG.

Further, as in the example shown in FIG. 16, the handbag adjusted so that the folded length Lg of the gusset portion 1 and the length L'between the pair of side wall sealing portions 2c and 2c satisfy the relationship of 4 Lg ≧ L'. Of course, also in the tool 10, the lower end corner portion (the portion corresponding to the shaded portion indicated by the reference numeral 14 in FIG. 5) may be cut.

Although the above-described embodiment is an example of a preferred embodiment of the present invention, the specific embodiment of the present invention is not limited to this, and various modifications can be carried out without departing from the gist of the present invention. is there. For example, in the above-described embodiment, the gusset portion 1, the side wall portion 2, and the handle portion 3 are all configured as one (in other words, formed by one member), but the handle portion 3 is a separate body. It may be configured as (in other words, formed of a separate member) and attached. In this case, the gusset portion 1, the side wall portion 2, and the handle portion 3 may be made of different materials.

Further, in the above-described embodiment, the side wall sealing portions 2c and 2c for sealing both ends in the gusset ridge direction X of the portion above the mountain fold ridge line 1a of the gusset portion 1 of the opposite side wall portions 2 and 2 are formed. However, the side wall sealing portion 2c is not an essential configuration in the present invention, and the side wall sealing portion 2c is not formed and both ends of the side wall portion 2 in the gusset ridge direction X are free ends. You may.

Further, in the above-described embodiment, the cutout portions 12 at both ends of the side wall are cut off, in other words, the sides of the pair of handle portions 3 and 3 in the gusset ridge direction X facing the side ends of the side wall portions 2 and 2 in the gusset ridge direction X. Although the ends are offset from each other, as shown in FIG. 8, the side wall cut ends 12 are not cut off, in other words, the pair of handles 3 and 3 face the side ends in the gusset ridge direction X. The side edges of the side wall portions 2 and 2 in the gusset ridge direction X may be aligned with each other. In this case, the side free end 2b (see FIG. 1) does not exist. In the example shown in FIG. 8, the side wall sealing portion 2c (see FIG. 1) is not formed, and both ends of the side wall portion 2 in the gusset ridge direction X are free ends.

Further, in the above-described embodiment, the angle of the side wall-gusset sealing portion 2d with respect to the gusset ridge direction X in the front view may be 45 ° or 90 ° as appropriate, but a plurality of side walls having different angles. -The gusset sealing portion 2d may be combined. Specifically, for example, as shown in FIG. 9, the side wall-sealing portion 2d1 (V seal) at an angle of 45 ° with respect to the gusset ridge direction X and an angle of 90 ° with respect to the gusset ridge direction X. It may be formed by combining the side wall-sealing portion 2d2 (that is, sealing all of the opposing side wall portions 2 and 2 and the gusset portion 1 together) (that is, in the orthogonal direction). In the example shown in FIG. 9, the gusset ridge direction X of the pair of handle portions 3 and 3 is formed while the side wall sealing portions 2c and 2c are formed at both ends of the side wall portions 2 and 2 in the gusset ridge direction X, respectively. The side ends of the side wall portions 2 and 2 facing the side end in the gusset ridge direction X are aligned with each other.

Here, in the above-described embodiment, the side wall-gusset sealing portion 2d is formed in the portion of the hand-carrying tool 10 where the gusset portion 1 is formed, and the side wall portion 2 along the side wall-gusset sealing portion 2d. And the lower end corner portion 14 of the gusset portion 1 is cut, whereby the amount of material used for the hand-carrying tool 10 can be saved, and the re-commercialization consignment fee for the hand-carrying tool 10 can be saved. I am trying to do it. The effect of forming the side wall-gusset sealing portion on the portion where the gusset portion is formed and cutting the side wall and the lower end corner portion of the gusset portion along the side wall-gusset sealing portion is as a hand-carrying tool. Is exhibited even if the specific embodiment of is not the one in the above-described embodiment.

Specifically, for example, even in the hand-carrying tool shown in FIG. 6, the effect of cutting the side wall and the lower end corner portion of the gusset portion is exhibited. The hand-carrying tool 20 shown in FIG. 6 is connected to the side wall portions 22 and 22 facing each other on the front surface and the back surface and both side ends of the side wall portions 22 and 22 facing each other, and faces each other in a folded state. Opposing gussets 21 and 21 that are sandwiched between the side walls 22 and 22 (front and back) and that form a part of the peripheral wall in a state where the handbag 20 is expanded and are connected to the side walls 22 and 22 and the side wall 22 , The lower end sealing portion 22b by heat fusion or the like that seals the portion of the side wall portions 22 and 22 facing each other at the lower end of 22 that does not overlap with the gusset portions 21 and 21 and the lower end sealing portion 22b facing the lower end sealing portion 22b. The opening end 22a is connected to each of the two gusset portions 21 and 21 and extends upward, and the upper ends of the handle portions 23 and 23 are sealed by heat fusion or the like. A side wall-gusset sealing portion 22c is formed in a portion having an upper end sealing portion 23a and a gusset portion 21 of each of the side wall portions 22 and 22 is formed, and the side wall-gusset sealing portion 22c is formed. The lower end corner portion 24 of the side wall portion 22 and the gusset portion 21 is cut along the line.

In the hand-carrying tool shown in FIG. 6, the angle between the side wall-gusset sealing portions 22c and 22c is such that the width of the lower end is narrower than the width of the intermediate portion of the side wall portions 22 and 22 in the front view of the hand-carrying tool 20. In other words, the side walls-gusset sealing portions 2d and 2d on both sides are arranged so as to form an upside-down C shape. The angle of the side wall-gusset sealing portion 22c with respect to the gusset ridge line direction (that is, the vertical direction) of the gusset portion 21 is set to 45 ° in the example shown in FIG. 6, but is limited to 45 °. However, it can be appropriately adjusted, and specifically, it can be appropriately adjusted in the range of, for example, about 30 ° to 60 °.

Also in the hand-carrying tool 20 shown in FIG. 6 described above, the side wall-gusset sealing portion 22c is formed in the portion where the gusset portion 21 is formed, and the side wall portion 22 and the gusset along the side wall-gusset sealing portion 22c. By cutting the lower end corner portion 24 of the portion 21, the amount of material used for the hand-carrying tool 20 can be saved, and the re-commercialization implementation consignment fee for the hand-carrying tool 20 can be saved.

Further, when the side wall-gusset sealing portion 22c is not formed when the direction of the mountain fold ridge line 21a of the gusset portion 21 is the vertical direction as in the hand-carrying tool 20, as shown in FIG. 7A, the side wall portions facing each other. At the lower ends of 32, 32 and both gussets 31, 31, a lower end sealing portion 32b is formed which collectively seals all of the side wall portions 32, 32 and the gusset portions 31, 31 over the entire width of the side wall portion 32. (Note that in FIG. 7A, the upper portion of the side wall portion including the handle portion is not limited to a specific form, so that the illustration is omitted. Specifically, the upper portion of the hand-carrying tool 20 shown in FIG. A similar form is possible). However, when the lower end sealing portion 32b over the entire width of the side wall portion 32 is formed when the gusset portion 31 in which the direction of the mountain fold ridge line 31a is the vertical direction is formed, as shown in FIG. 7B, the container is inside. A dent 33 (or a pocket) is formed by the facing side wall portions 32, 32 and the gusset portion 31 connected to the side wall portions 32, 32, and the dent 33 is formed, for example, a door lever or a handlebar brake of a bicycle. Easy to get caught in levers. Then, when the dent 33 is caught, the internal contents are tilted or tilted, the hand-carrying tool is damaged, or the hand or arm holding the hand-carrying tool is pulled and loses its posture. There is a problem.

On the other hand, when the side wall-gusset sealing portion is formed and the side wall portion and the lower end corner portion of the gusset portion are cut along the side wall-gusset sealing portion (specifically, for example, FIGS. 1 to 1 to 1). Since no dent (or pocket) is formed by the hand-carrying tool 10 shown in FIG. 5 or the hand-carrying tool 20) shown in FIG. 6, the opposite side wall portion and the gusset portion connected to these, the above-mentioned example of FIG. 7B. The problem caused by the dent 33 being caught by the protrusion or the like is avoided.

As in the examples shown in FIGS. 1 to 5, the side wall-gusset sealing portion 2d is formed and the side wall-gusset sealing portion 2d is formed in a configuration in which the direction of the mountain fold ridge line 1a of the gusset portion 1 is lateral. When the side wall portion 2 and the lower end corner portion 14 of the gusset portion 1 are cut along the gusset portion 1, the side wall is also configured such that the direction of the mountain fold ridge line 21a of the gusset portion 21 is the vertical direction as in the example shown in FIG. -When the gusset sealing portion 22c is formed and the side wall portion 22 and the corner portion 24 of the gusset portion 21 are cut along the side wall-gusset sealing portion 22c, the upper portion of the side wall portion including the handle portion The configuration is not limited to a specific configuration. Further, the angle between the side wall and the gusset sealing portion with respect to the gusset ridge line direction of the gusset portion is not limited to a specific angle, and can be appropriately adjusted in the range of, for example, about 30 ° to 60 °.

Further, as shown in FIG. 17A, the handle portion 3 may be provided with a through hole 43. As a result, when the handle portion 3 is grasped when the hand-carrying tool 10 is used, as shown in FIG. 17B, the handle portion 3 is folded back at the position where the through hole 43 is provided, and the entire handle portion 3 is randomly folded. The condition is avoided, the fit in the hand is improved, and the appearance is improved.

The shape and number of the through holes 43 are not limited to a specific shape and number, but the shapes are made into a perfect circle or an ellipse as shown in the examples shown in FIGS. It is preferable that a plurality of through holes 43 are provided side by side (that is, in a direction orthogonal to the gusset ridge direction X). Further, the position of the through hole 43 is preferably provided at the center position in the lateral direction of each handle portion 3 in the front view of the hand-carrying tool 10 in a folded state.
