Description

  The present invention is, for example, a pouch container filled with liquid commodities such as toilet cleaners, detergents, shampoos, etc., in particular, a spout portion on one side seal portion of a bottom gusset type pouch body having a pair of left and right side seals. It is related with the pouch container provided with independence.

  Liquid products such as toilet cleaners, detergents, and shampoos were sold in the state of being filled in bottle containers, but in recent years, liquid products such as shampoos have been simplified for effective use of bottle containers. Liquid goods for refilling filled in pouch containers are sold.

  Therefore, the consumer first purchases the liquid product filled in the bottle container or the like. However, if the liquid product is used up, the consumer does not purchase a new liquid product filled in the bottle container or the like. Instead, a liquid product for refill, which is the same product filled in a simple pouch container, is purchased, and only the liquid product is refilled into an empty bottle container or the like.

  An example of such a pouch container filled with liquid goods for refilling is as shown in FIG. In this pouch container 50, as shown in the figure, the gusset sheet 53 is folded inward from the lower ends of the pair of front and back exterior sheets 52, 52, and the peripheral edge of the gusset sheet 53 is heat sealed to the exterior sheets 52, 52. At the same time, the peripheral parts of the exterior sheets 52, 52 not overlapping the gusset sheet 53 are heat-sealed to each other, and the pouch body 51 is formed in a bag shape, and is attached to the upper edge of the pouch body 51. And a spout 54 that can be opened and closed by a screw cap.

  By the way, when refilling a liquid product filled in such a pouch container 50 into a bottle container or the like, as shown in FIG. 8, the pouch container 50 is turned upside down with the spout 54 fitted in the mouth of the bottle container. In recent years, as shown in FIGS. 9 (a) and 9 (b), the spout 54 is not the upper edge seal portion of the pouch body 51 but the side seal portion. The pouch container 50A attached to the container is desired. Note that the shaded display area in FIG. 4B shows the heat seal area.

Japanese Patent No. 3261543 (FIG. 5)

  As described above, in the pouch container 50A in which the spout 54 is attached to the side seal portion, when the filled liquid product is refilled into a bottle container or the like, it is not necessary to turn it upside down. Although the workability is good, there is a problem that the liquid product filled in the pouch container 50A partially remains in the pouch body 51 and the liquid product cannot be completely poured out.

  Therefore, an object of the present invention is to provide a pouch container that is excellent in the workability of pouring out the liquid contents and that can completely pour out the liquid contents.

  In order to solve the above problems, the invention according to claim 1 has a self-supporting property in which a spout portion is provided in one of the side seal portions of a bottom gusset type pouch body having a pair of left and right side seals. In the pouch container, the inner edge of one of the side seals in the pouch main body gradually approaches the other side seal side from the spout portion toward the bottom side of the pouch main body. A container is provided.

  According to a second aspect of the present invention, in the pouch container according to the first aspect of the present invention, a constriction is provided in the body of the pouch body by curving the outer edges of the pair of left and right side seals in the pouch body inward. It was.

  As described above, in the pouch container according to the first aspect of the present invention, the inner edge of one side seal provided with the spout portion in the pouch body is directed from the spout portion toward the bottom side of the pouch body. Since the pouch container is tilted to the side so that the spout portion faces downward, the inner edge of one side seal where the spout portion is provided becomes the spout. It gradually becomes higher from the part toward the bottom side of the pouch body. Therefore, when the liquid content filled in this pouch container is transferred to another container etc., the liquid content filled in this pouch container can be simply tilted sideways without lifting the bottom side more than necessary. Can be completely dispensed.

  Further, in the pouch container according to the second aspect of the present invention, the outer edge of the pair of left and right side seals in the pouch body is curved inward so that the body part of the pouch body is constricted. It becomes easier to grasp by hand and the handling of the pouch container is improved.

  Hereinafter, embodiments will be described with reference to the drawings. As shown in FIGS. 1 to 3, the pouch container 1 is filled with liquid or fluid contents such as toilet cleaners, detergents, shampoos, etc., such as linear low density polyethylene (LLDPE). A self-supporting bottom gusset-type pouch body 10 formed by a flexible sheet having a thickness of about 100 to 150 μm formed by laminating a polyamide film and a polyethylene terephthalate film on the outer surface of a heat-adhesive sealant film, and the pouch The spout 20 is formed of a heat-adhesive resin attached to one side edge of the main body 10 and can be opened and closed by a screw cap 21.

  2 and 3, the pouch body 10 includes a pair of front and back exterior sheets 11, 11 having a substantially rectangular shape, and a gusset sheet 12 that is folded between the lower ends of the exterior sheets 11, 11. Of the gusset sheet 12 that is folded between the exterior sheets 11 and 11, and the upper and both side edges of the exterior sheets 11 and 11 are heat-sealed to each other. The bottom gusset portion is formed by heat-sealing the periphery to the inner surfaces of the exterior sheets 11 and 11. Further, notches 12a are formed on both side edges of the gusset sheet 12 so as to match each other in a folded state, and the lower ends of both side edges of the exterior sheets 11 and 11 are connected to each other through the notches 12a. Is partially heat sealed. The shaded display area in FIG. 3 indicates the heat seal area.

  The exterior sheet 11 is curved inwardly at the center in the height direction of both side edges so that the neck portion of the pouch body 10 is constricted, but the two curved portions 11a and 11b are not symmetrical, It is formed asymmetrically so as to fit the hand when the body of the pouch body 10 is gripped by hand.

  Further, the inner edge of one side seal SSa to which the spout 20 in the pouch body 10 is attached gradually approaches the other side seal SSb side from the attachment position of the spout 20 toward the bottom gusset portion of the pouch body 10. As shown in FIG. 4, when the pouch container 1 is tilted sideways (the bottom outer edge of the pouch body 10 faces the vertical direction) so that the spout of the spout 20 faces downward, the spout in the pouch body 10 is The inner edge of one side seal SSa to which 20 is mounted is higher by Δh (= about 5 mm) on the bottom gusset side than the spout mounting position.

  Further, as shown in FIG. 3, the outer edge of the side seal SSa is on the same vertical line L with the spout 20 mounting position and the bottom gusset forming position except for the curved portion 11 a, Since the width is the same in the upper part and the lower part, as shown in FIG. 5 (a), the seal width of the side seal SSa in the bottom gusset part is formed wide, and when this pouch container 1 is filled with the contents The width of the bottom portion of the pouch body 10 and the width of the lower portion of the exterior sheet 11 are narrowed so that the seal width of the side seal SSa is the same in the vertical direction as shown in FIG. Comparing the width W2 of the bottom of the pouch body 10a when the object is filled, W1> W2, and the self-supporting stability is not lowered.

  As described above, in this pouch container 1, when the pouch container 1 is tilted sideways so that the spout of the spout 20 faces downward, one side seal SSa of the pouch body 10 to which the spout 20 is attached is installed. The inner edge of the pouch container 1 is raised by Δh (= about 5 mm) with respect to the spout mounting position on the bottom gusset side. Therefore, when the liquid content filled in the pouch container 1 is transferred to another container or the like, the pouch In the container 1, even if the bottom side is not lifted more than necessary, it is possible to completely pour out the filled liquid content by simply tilting it to the side, and the liquid content is easily poured out.

  Further, in this pouch container 1, by curving the outer edges of the pair of left and right side seals SSa, SSb in the pouch body 10 inward so as to fit the hand when the body part of the pouch body 10 is gripped by hand, Since the body part of the pouch body 10 is provided with an asymmetrical constriction, the body part of the pouch body 10 can be easily grasped by hand, and the handling property of the pouch container 1 is good. Moreover, since the width W1 at the bottom does not become narrow, the self-supporting stability does not deteriorate.

  In the above-described embodiment, in order to make it easier to grasp the body portion of the pouch body 10 by hand, the asymmetric curved portions 11a and 11b are provided on both side edges of the pouch body 10, but the present invention is not limited to this. However, both the curved portions may be symmetric, and it is not always necessary to provide the curved portions as in the pouch container 1A shown in FIG. As described above, even in the case where the bending portion is not provided, in order to ensure a good workability of the liquid content, the inner edge of one side seal SSa to which the spout 20 in the pouch body 10A is attached is provided. Needless to say, it is necessary to gradually approach the side seal SSb side of the other side seal from the attachment position of the spout 20 toward the bottom gusset portion of the pouch body 10A.

  Moreover, in embodiment mentioned above, although the spout 20 which can be opened and closed by the screw cap 21 is employ | adopted as a spout part, it is not limited to this, It is a nozzle-like opening opened by excising with a scissors etc. It is also possible to adopt a spout part.
