Has been proposed (see Patent Document 1).

JP 2011-78737 A

  According to the pouch container disclosed in Patent Document 1, the workability can be improved to some extent by inserting a finger into the through path and holding the container. However, in the case of the pouch container, as shown in the drawing of the same document, since the fingertip comes out from the through passage when the container is held, there is a possibility that a filling such as nutrients may be applied to the finger. There is room for improvement.

Pouch container according to the present invention, the wall sheet constituting at least the surface portion and the back surface, and a filling portion of contents surrounded by the sheet, the surface of the opening top of the container leading to front Symbol filling unit In the pouch container formed between the back surface portion and the back surface portion, the pouch container is provided with a bag-shaped portion provided on each of the top surface portion and the back surface portion, and each bag-shaped portion is isolated from the filling portion. It has an internal space and has an insertion port that allows a finger to be inserted into the space from the container width direction.

According to the said structure, a finger | toe can be inserted in the internal space of a bag-shaped part from a container width direction. Fingers (for example, thumb and forefinger) inserted into the bag-like portion are in a state along the container width direction, and the opening can be easily widened by opening the gap between the thumb and forefinger in this state.
Since the thumb and index finger are completely inserted into the bag-like portion, the container is excellent in retainability, and even when the contents are heavy, it is difficult to remove the finger and the container can be stably held. Since the thumb and forefinger are covered with the bag-like portion up to the fingertip, the filling material can be prevented from being applied to the finger. Moreover, since the opening state is maintained only by keeping a gap between the thumb and the index finger, for example, it is possible to prevent a problem that the opening portion is closed during filling operation and the filling material is spilled.

In the pouch container according to the present invention, it is preferable that each bag-like portion is provided over the entire width of the wall surface sheet.
According to the said structure, the pouch container provided with the bag-shaped part can be manufactured according to the process with high productivity using an elongate sheet | seat.

In the pouch container according to the present invention, it is preferable that the wall surface sheet is provided with a chuck for closing the opening, and the bag-like portions are provided above the chuck.
According to the said structure, since the filling part is hard to hide with the hand holding a container, it is easy to confirm the quantity of a filling material.

Further, in the configuration in which each bag-like portion is provided above the chuck, each insertion port is provided on one end side in the width direction of the bag-like portion, and between each bag-like portion, It is preferable that a seal portion that joins the other ends in the width direction is provided.
According to the said structure, it becomes easier to expand an opening part. When the other ends in the width direction are not joined, for example, when the interval between the thumb and the index finger is widened, each bag-like portion is easily bent outward at the base, but the bending is suppressed by providing a seal portion. And the force is likely to act in the direction of expanding the opening.

It is preferable that the seal part is formed without a gap along the vertical direction of each bag-like part.
According to the said structure, when injecting a filler, it can prevent a filler from leaking from the container width direction other end part. In addition, the other end region functions as a funnel, and the filler can be injected along the seal portion.

Moreover, in the structure provided with the said seal part, it is suitable for each said bag-like part to provide the bending formation part for forming the bending part along a container up-down direction. In particular, it is preferable to provide a bending portion on the other end in the width direction where a finger inserted into the bag-like portion does not reach.
According to the said structure, it becomes easier to expand an opening part. Since the pouch container is highly flexible, the portion of the bag-like portion where the finger is inserted has a shape along the finger. On the other hand, the portion located in front of the fingertip is, for example, curved from the position of the fingertip to the other end in the width direction or bent at the position of the fingertip, but when the opening is widened by providing a bending portion The bag-shaped portion is preferentially bent at the bend forming portion, and a bent portion (for example, a broken line) extending in the vertical direction of the container is formed. Thereby, for example, a portion located in front of the fingertip extends straight to the fold line (bending portion) along the finger, and the opening becomes easier to spread.

Further, in the configuration in which each bag-like portion is provided above the chuck, each bag-like portion is formed by one gusset sheet inserted between the front surface portion and the back surface portion, It can be set as the structure by which the cutting auxiliary line was formed on the crease line of a gusset sheet | seat.
According to the said structure, when using a container, it becomes possible to isolate | separate each bag-like part by cut | disconnecting a gusset sheet along a cutting auxiliary line, and to open an opening part. Before use, for example, since the gusset sheet covers the upper portion of the chuck, the sealing performance of the filling portion is improved.

In the pouch container according to the present invention, each bag-like portion is provided with a tongue piece that closes each insertion opening, and each insertion opening is opened by folding the tongue piece into the internal space. Is preferred.
According to the said structure, it becomes easy to insert a finger in a bag-shaped part. The tongue piece folded into the internal space, for example, raises the edge of the insertion opening, thereby improving the finger insertability.

In the pouch container according to the present invention, each insertion port is provided on one end side in the width direction of the bag-shaped portion, and the upper portion on the other end side in the width direction than the insertion port of the bag-shaped portion It is preferable that a finger-hanging seal portion for joining the inner surfaces of the bag-like portions is provided.
According to this configuration, for example, the tip of the thumb can be hooked on the finger-hanging seal portion, so that the thumb hook in the bag-like portion is improved and the force is easily applied in the direction of expanding the opening. This configuration is particularly useful for women with small hands.

  ADVANTAGE OF THE INVENTION According to this invention, while being able to prevent malfunctions, such as a filler covering a finger | toe, the pouch container which can hold | maintain a container stably, expanding an opening part can be provided.

However, the filling material is not limited to this, and may be, for example, water for diluting the nutrient, or may be a jelly-like or paste-like material. The application of the present invention is not limited to medical use, and may be applied to containers for various food products.

  In the following, a flat pouch in which the portion excluding the bag-like portion is composed only of the top sheet 11 and the back sheet 12 will be exemplified, but the configuration of the present invention is applied to other pouch forms such as a standing pouch and a side gusset pouch. Also good.

  In this specification, the part where the opening is formed is the “upper part” of the container, and the part facing the upper part is the “lower part” of the container. Also, the direction in which the sheets are laminated is the “front and back direction” of the container, and the direction perpendicular to the vertical direction and the front and back direction is the “width direction” of the container. Hereinafter, the vertical direction, the front / back direction, and the width direction may be simply referred to.

<First Embodiment>
The pouch container 10 according to the first embodiment will be described in detail with reference to FIGS.
First, reference will be made to FIGS. 1 and 2 are front views of the pouch container 10, and FIG. 2 shows a state in which the tongue pieces 26A and 26B are folded inside the bag-like portions 20A and 20B (internal spaces 22A and 22B). FIG. 3 shows a cross section when the bag-like portions 20A and 20B are cut in the front and back direction along the line AA in FIG. 2 parallel to the width direction.

  The pouch container 10 includes a top sheet 11 and a back sheet 12 that are overlapped with each other. The top sheet 11 and the back sheet 12 are a pair of wall surface sheets that respectively constitute the front surface portion and the back surface portion of the container. The pouch container 10 has an edge seal portion 13 formed by joining edges except for the upper edge of each sheet. That is, the edge seal part 13 is formed in the width direction both ends (side edge) and lower end edge of the front and back sheets, and an opening 15 (see FIG. 7 described later) connected to the filling part 14 is formed in the upper part of the container. ing. The opening 15 is an opening facing upward, and is formed between the sheets when the top sheet 11 and the back sheet 12 are not joined.

  The pouch container 10 is provided with a chuck 16 that closes the opening 15. The container inner space surrounded by the wall surface sheet is sealed by the edge seal portion 13 and the chuck 16. This sealed container internal space is a filling portion 14 filled with a nutrient. The chuck 16 is configured by, for example, opposingly arranging a first sheet with a ridge and a second sheet with a ridge that fits into the ridge. For example, the first sheet is bonded to the inner surface of the top sheet 11, and the second sheet is bonded to the inner surface of the back sheet 12.

  Further, the pouch container 10 is provided with a dispensing unit 17 for dispensing the nutrients filled in the filling unit 14. The pouring part 17 is a plastic tube with a stopper, for example, and is attached to the corners of the lower end and the side end cut obliquely of the wall surface sheet. Specifically, the pouring part 17 is attached by joining each member with the pouring part 17 sandwiched between the top sheet 11 and the back sheet 12.

  Further, the pouch container 10 is provided with a hanging hole 18 on an extension line in the longitudinal direction of the pouring part 17. The suspension hole 18 is formed by forming a part of the edge seal portion 13 wide and punching the wide seal portion in the front and back direction. When administering the nutrient filled in the pouch container 10 to the patient, the longitudinal direction of the dispensing portion 17 is in the vertical direction by hooking the hanging hole 18 on a hook or the like, so that the nutrient can be easily used. Can be dispensed.

  In the pouch container 10, a cut portion 19 is formed on the side opposite to the width direction end where the hanging hole 18 is formed, and the width of the upper portion of the container is narrower than the width of the lower portion of the container. By reducing the width of the upper portion of the container, particularly by cutting the side of the later-described insertion ports 24A and 24B to reduce the width, the retainability of the container can be improved.

  Furthermore, the pouch container 10 includes a bag-like portion 20A provided on the upper surface portion and a bag-like portion 20B provided on the upper surface portion. The bag-like portions 20A and 20B are portions used when the opening 15 is expanded and the nutrient is injected into the filling portion 14, and a pair of wall surface sheets and a bag-like portion forming sheet 21A inserted therebetween. , 21B (hereinafter simply referred to as “sheets 21A, 21B”). Specifically, the sheet 21A and the top sheet 11 are joined by the edge seal part 23A, and the sheet 21B and the back sheet 12 are joined by the edge seal part 23B, thereby forming the bag-like parts 20A and 20B.

  Each sheet constituting the pouch container 10 is usually made of a resin film. The resin film constituting the sheet is required to have basic performance as a packaging body such as impact resistance, wear resistance, and heat resistance. Moreover, since each said seal | sticker part is normally formed by a heat seal, the heat seal property is also requested | required of a sheet | seat. As the sheet, a multilayer sheet having a base film layer and a sealant layer that imparts heat sealability is suitable, and when high gas barrier properties are required, a gas barrier is provided between the base film layer and the sealant layer. It is preferred to provide a layer.

  Here, constituent materials of the base film layer, the sealant layer, and the gas barrier layer are exemplified. In addition, lamination | stacking of these each layer can be performed by the conventional lamination method, for example, the dry lamination by an adhesive agent, the heat lamination which adhere | attaches with a heat | fever by pinching | interposing a heat bonding layer.

  Examples of the film constituting the base film layer include polyester (polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), polycarbonate (PC), etc.), polyolefin (polyethylene (PE), polypropylene ( PP), etc.), polyamide (nylon-6, nylon-66, etc.), polyacrylonitrile (PAN), polyimide (PI), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polymethyl methacrylate (PMMA), poly A stretched or unstretched film having one layer or two or more layers composed of ether sulfone (PES) and ethylene-vinyl alcohol copolymer (EVOH) can be exemplified.

  The films constituting the sealant layer include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), ethylene-propylene copolymer (EP), unstretched polypropylene (CPP), and biaxially stretched nylon (ON). , Ethylene-olefin copolymer, ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-vinyl acetate copolymer (EVA), etc. A stretched or unstretched film can be exemplified.

  The gas barrier layer may be a metal thin film such as aluminum, a resin film such as vinylidene chloride (PVDC) or ethylene-vinyl alcohol copolymer (EVOH), or any synthetic resin film (for example, a base film layer). ), And a film obtained by vapor-depositing (or sputtering) an inorganic oxide such as aluminum, aluminum oxide or silica.

  For example, the wall sheet is preferably provided with a scale (not shown) for measuring the amount of nutrient solution. In addition to the scale, a print layer for displaying a trade name, raw materials, usage precautions, and the like may be provided.

  Hereinafter, the configuration of the bag-like portions 20A and 20B will be described in further detail.

  The pouch container 10 includes bag-like portions 20 </ b> A and 20 </ b> B above the chuck 16. The chuck 16 is provided along the width direction, and the bag-like portions 20A and 20B are provided substantially parallel to the chuck 16 (width direction). The pouch container 10 is in the form of a flat pouch composed of two wall sheets below the chuck 16, but is composed of four sheets above the chuck 16. As described above, the bag-shaped portion 20A is formed by bonding the sheet 21A to the inner surface of the top sheet 11, and the bag-shaped portion 20B is formed by bonding the sheet 21B to the inner surface of the back sheet 12. .

  The bag-like portions 20 </ b> A and 20 </ b> B overlap with each other in the front and back direction, and are opposed to each other with the opening 15 interposed therebetween. In the present embodiment, the sheets 21A and 21B are not joined to each other, and the bag-like portions 20A and 20B are separated. The bag-like portions 20A and 20B have a substantially rectangular shape that is longer in the width direction than the vertical direction, and have the same shape and the same dimensions. Hereinafter, the contents common to the bag-like portions 20A and 20B will be described by taking the bag-like portion 20A as an example.

  The bag-shaped portion 20A is provided over the entire width of the wall surface sheet. In other words, the width direction length of the portion of the wall surface sheet located above the chuck 16 is the same as the width direction length of the sheet 21A. Although the length in the width direction of the sheet 21A may be shorter, it is preferable to adopt the configuration from the viewpoint of productivity. Thereby, the pouch container 10 can be manufactured simply and inexpensively by an existing bag making process using a long sheet.

  The bag-like portion 20 </ b> A has an internal space 22 </ b> A that is isolated from the filling portion 14. The bag-like portion 20A has an insertion port 24A that allows a finger to be inserted into the internal space 22A from the width direction. In the form shown in FIG. 1, the insertion port 24A is closed by a tongue piece 26A described later.

  The internal space 22A is an independent space that does not communicate with the filling portion 14, and the peripheral edge in the front view state (see FIG. 1) is closed by the edge seal portion 23A. The internal space 22A has a dimension capable of accommodating at least one finger, for example, a thumb (for example, an index finger is accommodated in the internal space 22B). More specifically, it is preferable to set the dimensions so that they can be accommodated from the tip of the finger to the root. Further, since the finger is accommodated in the state along the width direction, the internal space 22A is a space that extends long in the width direction. In the internal space 22A, only the insertion port 24A is a connection port with the outside, and the other part is closed by the seat and the edge seal portion 23A.

  The insertion opening 24A is provided on one end side in the width direction of the bag-like portion 20A in which the cut portion 19 is formed, that is, on the opposite side to the other end in the width direction in which the hanging hole 18 is formed. The insertion port 24B is provided just behind the insertion port 24A. The insertion port 24A is designed such that a finger is inserted from one end side in the width direction, and the finger inserted from the insertion port 24A is accommodated in the internal space 22A with the fingertip facing the other end side in the width direction. .

  24 A of insertion ports are provided by forming the cut line 25A in the outer surface (surface sheet 11 which comprises the bag-shaped part 20A) of a surface part. From the viewpoint of container retainability and the like, it is preferable to form the cut line 25A close to one end in the width direction.

  The cut line 25 </ b> A has a substantially U shape when viewed from the front, and is formed so that both ends (hereinafter referred to as “cut ends”) face the other end in the width direction. That is, the substantially straight portion of the cut line 25A is formed along the width direction, and the arc-shaped portion of the cut line 25A is formed so as to protrude toward the one end side in the width direction. The bag-like portion 20A is provided with a tongue piece 26A which is a portion surrounded by a cut line 25A and a line connecting the cut ends (hereinafter referred to as “root line of the tongue piece 26A”) (FIG. 1). The insertion port 24A is opened by bending the tongue piece 26A at the base line (see FIG. 2). When a finger is inserted into the insertion opening 24A from one end in the width direction, the finger is inserted from between the edge (that is, the root line portion) on the other end in the width direction and the sheet 21A.

  The cut line 25 </ b> A has a lower straight portion that is longer than the upper straight portion in order to improve the retainability of the container while facilitating insertion of a finger. And a base line has the lower end located in the width direction other end side rather than an upper end, and is inclined with respect to the up-down direction and the width direction. Thus, the size of the insertion port 24A is increased below the finger where the weight of the container is not applied, and the size of the insertion port 24A is decreased above the finger where the weight of the container is applied. This reduces the burden on the finger and makes it easier to insert the finger.

  The tongue piece 26A is preferably folded inside (inside the internal space 22A) (see FIGS. 2 and 3). The tongue piece 26A is connected to the edge of the insertion opening 24A on the other end side in the width direction, and the edge is easily lifted by folding it inward. That is, in this configuration, in order to improve finger insertion, a gap for inserting a finger (gap between the edge and the sheet 21A) is widened using the tongue piece 26A. The tongue piece 26A may be folded at the time of use, or may be folded at the time of manufacture. Further, the tongue piece 26A may be joined to the top sheet 11 in a state of being folded inward.

FIG. 4 shows a modification of the first embodiment. FIG. 4 is a perspective view of the bag-like portions 20A and 20B as viewed obliquely from above, and is a cross-sectional view of a part cut in the vertical direction.
In the form shown in FIG. 4, bag-like portions 20A and 20B are formed using a gusset sheet 21G instead of the sheets 21A and 21B. The gusset sheet 21G is a V-shaped sheet that is folded in a downward direction and viewed in a cross section. The gusset sheet 21G is inserted between the pair of wall surface sheets so that the crease line 27 is substantially parallel to the width direction. Then, one sheet portion divided into two by the crease line 27 is joined to the inner surface of the top sheet 11, and the other sheet portion is joined to the inner surface of the back sheet 12, so that two bag-like portions 20A and 20B are formed. Yes.

  In the form shown in FIG. 4, since the bag-like portions 20A and 20B are formed by a pair of wall sheets and one gusset sheet 21G, the bag-like portions are connected to each other before use (before opening). . Thereby, the sealing performance of the filling part 14 before opening can be improved. In the gusset sheet 21G, for example, a cutting auxiliary line such as a half-cut line or a perforation line can be formed on the crease line 27. By using the gusset sheet 21G along the cutting auxiliary line, a bag shape can be formed. The parts 20A and 20B can be separated from each other. By the separation, a form similar to that when the sheets 21A and 21B are used is obtained, and the opening 15 can be opened.

  Next, an example of a method for manufacturing the pouch container 10 having the configuration of FIG. 1 will be described with reference to FIG. FIG. 5 schematically shows a process of laminating long sheets of sheets and forming each seal portion in the manufacturing process of the pouch container 10.

  As shown in FIG. 5, first, the top sheet 11, the back sheet 12, the sheets constituting the chuck 16 (for example, the first sheet with the ridges and the second sheet with the ridges), and the sheet 21A. , 21B (hereinafter referred to as “long bodies 11z, 12z, 16z, 21Az, 21Bz”) are prepared and laminated together. The long body 16z is stacked in a state in which the protruding strip portion of the first sheet and the concave strip portion of the second sheet are fitted, and the long bodies 21Az and 21Bz are stacked in a state of being overlapped with each other. .

  In the laminating process of the long bodies, first, the long bodies 16z, 21Az, and 21Bz are inserted between the long bodies 11z and 12z that are overlapped with each other. At this time, the long bodies 11z and 12z are laminated so that the sealant layers face each other, and the sealant layer of the long body 21Bz faces the sealant layer of the long body 11z so that the sealant layer of the long body 11z faces the sealant layer of the long body 11z. It is laminated so as to face the sealant layer of the long body 12z. Thereby, said each seal | sticker part can be formed, preventing elongate body 21Az and 21Bz joining in a heat seal process.

  Each sealing part is formed in each said elongate body which passed through the lamination process at a heat sealing process. In the heat sealing process, for example, the edge seal portion 13 is formed by heat-sealing a predetermined portion along the TD direction at the lower edge of the long bodies 11z and 12z, leaving a portion to which the extraction portion 17 is attached. Here, the lower end edge of the elongated body is a part that becomes the lower end edge of the pouch container 10, and the predetermined part is a part that becomes the side end edge of the pouch container 10. In the heat sealing step, the long bodies 16z, 21Az, and 21Bz are further joined to the long bodies 11z and 12z, respectively. Thereby, the opening part 15 is closed and edge seal parts 23A and 23B are formed.

  Subsequently, for example, the long body is cut along the planned cutting line X using a die cut roll or the like, and is divided into individual container sizes. In addition, the said heat seal and the said cut may be performed simultaneously. At this time or in another process, the hanging hole 18 and the cut lines 25A and 25B are formed. Thereby, bag-like parts 20A and 20B into which fingers can be inserted are formed in the internal spaces 22A and 22B. Finally, the pouring part 17 is attached and the pouch container 10 is obtained.

  In this manufacturing process, the example using the long bodies 21Az and 21Bz for manufacturing the pouch container shown in FIG. 1 has been described. However, in order to manufacture the pouch container having the form shown in FIG. A long gusset sheet 21G may be used instead of 21Az and 21Bz. Further, in order to manufacture the pouch container shown in FIG. 1, the long gusset sheet 21G is supplied to the bag making machine and is heat sealed to the wall surface sheet or after heat sealing, and then the gusset sheet 21G along the crease line. May be separated into elongated bodies 21Az, 21Bz or bag-like portions 20A, 20B, or the upper portions of the wall surface sheet may be folded back inward or outward to form bag-like portions 20A, 20B. .

  Next, the effects of the pouch container 10 will be described in detail with reference to an example of the usage state of the pouch container 10 shown in FIGS.

  When injecting a nutrient from the opening 15 of the pouch container 10 into the filling part 14, for example, the chuck 16 is opened and the opening 15 is widened while holding the container with one hand (hereinafter referred to as the right hand). First, a thumb is inserted into the internal space 22A of the bag-like portion 20A, and an index finger is inserted into the internal space 22B of the bag-like portion 20B to hold the container. At this time, the thumb and index finger are inserted into each internal space from the one end side in the width direction through the insertion openings 24A and 24B. The insertion ports 24A and 24B are formed by substantially U-shaped cut lines 25A and 25B which are formed close to one end in the width direction and which are longer on the lower side than on the upper side, and tongue pieces 26A and 26B. Is folded inside and opened. For this reason, a finger can be smoothly inserted from the insertion openings 24A and 24B.

  Subsequently, the chuck 16 is removed to widen the opening 15 by opening a gap between the thumb inserted into the bag-like portions 20A and 20B and the index finger. That is, the thumb is moved to the front side and the index finger is moved to the back side. By further increasing the distance between the thumb and the index finger, the opening 15 can be greatly expanded.

  Subsequently, injecting nutrients is started in a state where the gap between the thumb and index finger is widened to widen the opening 15. Since the opening state is maintained simply by keeping the gap between the thumb and the index finger, for example, the nutrient can be injected close to the base of the bag-like portions 20A and 20B, and the opening 15 is closed during the injection operation. This prevents the nutrients from spilling. Moreover, although the weight of the container is increased by injecting the nutrient, the finger holding the container is completely inserted into the bag-like portions 20A and 20B, so that it is difficult to remove and the container can be stably held. . Furthermore, even when nutrients accidentally flow out of the container, the thumb and forefinger are covered with each bag-like portion up to the fingertips, so that the nutrient can be prevented from being applied to the fingers.

  As described above, according to the pouch container 10, it is possible to easily perform the nutrient injection process while holding the container with one hand, and it is possible to greatly improve the workability of the injection process.

<Second Embodiment>
With reference to FIGS. 8-11, the pouch container 30 which is 2nd Embodiment is demonstrated. Here, differences from the first embodiment will be mainly described, and the same components as those in the first embodiment will be denoted by the same reference numerals, and redundant description will be omitted.

  As shown in FIG. 8, the pouch container 30 is different from the pouch container 10 in that the other end portions in the width direction of the bag-like portions 20 </ b> A and 20 </ b> B are joined to each other and a seal portion 31 is provided. The seal portion 31 is provided on the side opposite to the insertion ports 24A and 24B. In the form shown in FIG. 8, notches 32A and 32B are formed at the other widthwise ends of the sheets 21A and 21B, respectively, and the seal portion 31 is provided only at the portion where the notches 32A and 32B are formed. It is a seal part. Specifically, the seal part 31 has a form in which the inner surfaces of the top sheet 11 and the back sheet 12 are joined to each other through the notches 32A and 32B.

  9 and 10 show a modification of the embodiment shown in FIG. In the form shown in FIGS. 9 and 10, the seal portion 31 is formed without a gap along the vertical direction of each bag-like portion. The seal portion 31 is preferably formed by joining the sheets 21A and 21B. The sealing portion 31 is formed by a heat sealing process using, for example, so-called double-sided heat-sealable sheets 21A and 21B having a sealant layer in the entire area or a part of both surfaces. Note that, for example, the softening temperature of the sealant layer on the surface where the sheets 21A, 21B face each other is the surface facing the wall sheet so that the sheets 21A, 21B are heat-sealed only at the other widthwise ends of the bag-like portions 20A, 20B. It can be set higher than the softening temperature of the sealant layer. Further, the sheets 21A and 21B may be joined with an adhesive.

  As shown in FIG. 11, the opening 15 can be more easily spread by providing the seal portion 31 and joining the other ends in the width direction of the bag-like portions 20 </ b> A and 20 </ b> B. For example, the opening 15 can be opened more largely with a smaller force than when the other ends in the width direction are not joined to each other (first embodiment). In the first embodiment, for example, when the interval between the thumb and the index finger is widened, each bag-like portion may be bent outwardly at the base or the like, and only each bag-like portion may be opened outwardly. By fixing the other end portions in the direction so that the other end portion in the width direction does not open to the outside, a force easily acts in the direction of expanding the opening 15. Thereby, the opening property of the opening part 15 further improves.

  Furthermore, by forming the seal portion 31 without any gap along the vertical direction of each bag-like portion, it is possible to prevent the nutrient from leaking from the other end in the width direction when the nutrient is injected. In addition, the other end region functions as a funnel, and it is possible to inject a nutrient along the seal portion 31.

<Third Embodiment>
A pouch container 40 according to the third embodiment will be described with reference to FIGS. In the following, differences from the above embodiment will be mainly described, and the same components as those in the above embodiment will be denoted by the same reference numerals and overlapping description will be omitted.

  As shown in FIG. 12, the pouch container 40 is pouched in that notches 41A and 41B which are bent forming portions are provided on the edge seal portions 23A and 23B located at the upper end edges of the bag-like portions 20A and 20B. Different from the container 30. The notches 41A and 41B are positions where the fingertips inserted into the bag-like portion between the widthwise central portion of the bag-like portions 20A and 20B and the other end in the width direction cannot reach, for example, the fingertips inserted into the bag-like portion And the other end in the width direction.

  The fold forming portion has a function of forming a bent portion (for example, a broken line) extending in the vertical direction by locally reducing or increasing the rigidity of the bag-like portion. The bending portion is not limited to the notch, and may be, for example, a perforation line 42 along the vertical direction shown in FIG. 13 or a seal portion 43 along the vertical direction shown in FIG. Further, a half cut line may be formed instead of the perforation line 42, and as shown in FIG. 15, a wide seal portion 44 may be formed from the position of the seal portion 43 to the other end in the width direction. . The seal portions 43 and 44 can be formed, for example, by heat sealing the inner surfaces of the bag-like portions. Note that the perforation line 42, the seal portions 43, 44, and the like are preferably formed not only in the bag-shaped portion 20A but also in the bag-shaped portion 20B.

  As shown in FIG. 16, by providing the notches 41A and 41B in front of the fingertips inserted into the bag-like portions 20A and 20B, the openability of the opening 15 can be further improved. For example, the portions of the bag-like portions 20A and 20B that are positioned forward of the fingertip are curved from the position of the fingertip to the other end in the width direction or bent at the position of the fingertip (see FIG. 11). Therefore, by providing the notches 41A and 41B, the bag-like portions 20A and 20B are preferentially bent at the portion where the notches 41A and 41B are formed, and the folding lines 42A and 42B along the vertical direction are easily formed. Thereby, the part located ahead of the fingertip extends straight to the position of the fold lines 42A and 42B along the finger, and the opening 15 becomes easier to spread. The opening shape of the opening 15 exhibits, for example, a substantially home base shape when viewed from above.

<Fourth Embodiment>

  The pouch container 70 has cut portions 71 and 72 formed on both sides in the width direction of the upper part of the container so that the width of the upper part of the container is smaller than the width of the lower part of the container, and two insertion ports are formed in the bag-like part 20A. Is different from the pouch container 10 in that cut lines 25A and 73A are provided (the same applies to the bag-like portion 20B). The cut line 73A is formed close to the other end in the width direction of the bag-shaped portion 20A, and has a substantially U-shape in front view, similar to the cut line 25A. The cut line 25A is designed such that a finger is inserted from one end in the width direction, and the cut line 73A is designed such that a finger is inserted from the other end in the width direction. Since the pouch container 70 has a narrow upper half width and a short length in the width direction of each bag-like portion, for example, a fingertip inserted into the bag-like portion is located in the center in the width direction. Or it is located in the vicinity of the width direction edge part on the opposite side beyond the width direction center part. Thereby, for example, a force for expanding the opening 15 acts over the entire width of the opening 15, and the opening 15 can be greatly expanded with a small force. Moreover, it becomes easier to maintain the opening state of the opening 15.

<Seventh Embodiment>
With reference to FIG. 20, the pouch container 80 which is 7th Embodiment is demonstrated.

  The pouch container 80 has the same outer shape as the pouch container 70, but differs from the pouch container 70 in that a bag-shaped portion 20A is provided below the chuck 16 (the same applies to the bag-shaped portion 20B). The bag-shaped portion 20A is formed, for example, by bonding a sheet 21A to the inner surface of the topsheet 11. The cut lines 25 </ b> A are formed in the top sheet 11. An edge seal portion 13 is formed in a portion of the pair of wall surface sheets located above the chuck 16 in order to increase the sealing performance of the filling portion 14. An opening notch 74 is formed between the edge seal portion 13 and the chuck 16.
