[0010] [Embodiment 1] A pouch container 1 according to one embodiment of the present invention will be described below with reference to the drawings. However, the following description is merely an example of a pouch container according to the present invention, and the technical scope of the present invention is not limited to the illustrated example.

[0011] [Configuration of pouch container 1] Fig. 1 is a plan view showing the front side of a pouch container 1 according to a first embodiment of the present invention. Fig. 2 is a plan view showing the back side of the pouch container 1 shown in Fig. 1. Fig. 3 is a plan view showing the top sheet 22 shown in Fig. 1. Figs. 1 and 2 show the pouch container 1 in a folded state when not filled with contents. Also, Fig. 3 does not show the handle 4.

[0012] In Figure 1, the up-down, left-right, and front-rear directions are defined based on the state in which the pouch container 1 is filled with contents and stands upright (see Figure 4), with the height direction of the pouch container 1 defined as the up-down direction, the width direction of the pouch container 1 defined as the left-right direction, and the direction perpendicular to the up-down and left-right directions defined as the front-rear direction. All directions shown in Figure 2 and subsequent figures are indicated in accordance with the directions defined in Figure 1.

[0013] 1 and 2, the pouch container 1 according to this embodiment comprises a container body 2 formed from a flexible sheet having an annular body 21, a top sheet (first end sheet portion) 22, and a bottom sheet (second end sheet portion) 23, a spout 3 protruding from the top sheet 22, and a handle 4. By devising an ingenious attachment position of the spout 3 and the handle 4 relative to the container body 2, the present disclosure provides a pouch container 1 that is easy to carry and pour from.

[0014] (Container body 2) The body 21 of the container body 2 includes a front sheet (first body sheet portion) 21a and a back sheet (second body sheet portion) 21b facing the front sheet 21a. The body 21 is configured into a cylindrical shape by joining both widthwise (left and right) side portions of the front sheet 21a and the back sheet 21b. Specifically, the body 21 has a pair of first seal portions (joint portions) S1 that seal both widthwise side portions of the front sheet 21a and the back sheet 21b, and the front sheet 21a and the back sheet 21b are joined into a cylindrical shape by these first seal portions S1.

[0015] For the sake of convenience, the front sheet 21a and the back sheet 21b are used to distinguish between two opposing sheets that form the body 21. In other words, this does not mean that the front sheet 21a side is limited to the front side of the container body 2, and the positional relationship between the front sheet 21a and the back sheet 21b may be reversed.

[0016] The top sheet 22 is joined to the upper end (one end) of the body portion 21. Specifically, the upper end of the front sheet 21a and the front edge of the top sheet 22 are sealed by a second sealed portion S2. The upper end of the back sheet 21b and the back edge of the top sheet 22 are sealed by a third sealed portion (joint portion) S3. The second sealed portion S2 and the third sealed portion S3 are connected to each other at a first connecting portion 201 corresponding to the left end of the top sheet 22 and a second connecting portion 202 corresponding to the right end of the top sheet 22, thereby surrounding the edge of the top sheet 22. The second sealed portion S2 and the third sealed portion S3 are connected to one (left) first sealed portion S1 at the first connecting portion 201 and to the other (right) first sealed portion S1 at the second connecting portion 202.

[0017] As shown in FIG. 3 , the topsheet 22 according to this embodiment has a longitudinal direction in the width direction. Each of the widthwise ends of the topsheet 22 is tapered outward in the width direction, resulting in a generally hexagonal shape overall. According to the shape of the topsheet 22, a bent portion 221 forming an angle is formed to the left of the second seal portion S2 on the front sheet 21a side, and a bent portion 222 forming an angle is formed to the right of the second seal portion S2. Furthermore, a bent portion 223 forming an angle is formed to the left of the third seal portion S3 on the backsheet 21b side, and a bent portion 224 forming an angle is formed to the right of the third seal portion S3. The bent portions 221 and 223 face each other across the topsheet 22. Similarly, the bent portions 222 and 224 face each other across the topsheet 22.

[0018] When the pouch container 1 is in a folded state, the widthwise distance d1 between the first sealed portion S1 and the bent portions 221-224 is preferably between 1 / 6 and 1 / 3 of the width dimension W of the container body 2 excluding the width of the first sealed portion S1 on both the left and right sides. By making the distance d1 at least 1 / 6 of the width dimension W, the area of ​​the first tapered portion R1 and the second tapered portion R2 is ensured, making it easier to stably position the spout 3. Furthermore, by making the distance d1 between 1 / 6 and 1 / 3 of the width dimension W, the container body 2 assumes a shape similar to a prismatic column when contents are placed in the pouch container 1, improving the container body 2's ability to stand on its own.

[0019] If the imaginary line segment connecting bent portion 221 and bent portion 223 is defined as a first line segment L1, and the imaginary line segment connecting bent portion 222 and bent portion 224 is defined as a second line segment L2, then top sheet 22 includes three regions: a first tapered portion R1 located to the left of first line segment L1, a second tapered portion R2 located to the right of second line segment L2, and a rectangular central portion R3 located between first line segment L1 and second line segment L2. A spout 3 is provided in first tapered portion R1, as described below. Furthermore, a first adhesive portion 42 and a second adhesive portion 43 of hand-carrying member 4 are adhered to central portion R3, as described below.

[0020] The inclination angle θ of each inclined side of the top sheet 22 sandwiching the first tapered portion R1 in the front-to-rear direction is preferably, for example, 30° to 60°. When the inclination angle θ is within this range, the first tapered portion R1 is inclined when the pouch container 1 is in use with contents stored therein, and the spout 3 is held at an angle that makes it easy to pour the contents (see FIG. 4).

[0021] The upper sheet 22 may have an asymmetrical shape, with the left and right sides having different shapes, for example, the inclination angle θ may be different between the left and right sides. Also, instead of a shape with corners such as a substantially hexagonal shape, the upper sheet 22 may have a curved shape.

[0022] The bottom sheet 23 is joined to the lower end (other end) of the body portion 21. Specifically, the lower end of the front sheet 21a and the front edge of the bottom sheet 23 are sealed at a fourth seal portion (joining portion) S4. The lower end of the back sheet 21b and the back edge of the bottom sheet 23 are sealed at a fifth seal portion (joining portion) S5. Furthermore, notches 232 are provided in part on both sides of the bottom sheet 23 in the width direction, and the bottom sheet 23 is heat-sealed while sandwiched between the front sheet 21a and the back sheet 21b, thereby sealing both sides of the front sheet 21a and both sides of the back sheet 21b at the positions of the notches 232. The container body 2 is capable of standing on its own with the bottom sheet 23 facing downwards.

[0023] When the container body 2 is folded, the bottom sheet 23 is folded between the front sheet 21a and the back sheet 21b, and is folded in half so as to form a woven line 231 that runs along the width direction of the pouch container 1. The top sheet 22 and the bottom sheet 23 may have the same shape or different shapes.

[0024] In this way, the container body 2 in the pouch container 1 of this embodiment is formed in a bag shape by joining together the front sheet 21a, back sheet 21b, top sheet 22, and bottom sheet 23, and has a storage section 25 formed inside that can store contents such as liquid.

[0025] The sheets constituting the container body 2 can be joined together by various known methods, such as fusion bonding using heat sealing, ultrasonic sealing, high-frequency sealing, or adhesive bonding. The container body 2 is not limited to the above-described configuration in which four different sheets, the front sheet 21a, the back sheet 21b, the top sheet 22, and the bottom sheet 23, are joined together. For example, the container body 2 may be formed by folding a single sheet to form the front sheet 21a, the back sheet 21b, and the bottom sheet 23, and then joining the top sheet 22. The container body 2 may also be formed by folding a single sheet. The shape of the top sheet 22 may be formed by joining the sheets together in a bag shape and then cutting away unnecessary portions to fit the outer shape.

[0026] The contents contained in the pouch container 1 may be a fluid liquid, viscous substance, granules, or powder. Examples of the contents include beverages, liquid hair care products such as shampoo, hair conditioner, and hair rinse, liquid soaps such as body soap and hand soap, liquid detergents for clothes and dishes, fabric softeners and bleaches, liquid cleaners for bathrooms, toilets, and floors, liquid cosmetics, liquid medicines, disinfectants, chemicals such as alcohol, liquid fuels, oils, granular foods, feed, detergents, industrial materials such as resin pellets, and the like.

[0027] The flexible sheet constituting the container body 2 is made of, for example, a thermoplastic resin. Examples of the flexible sheet include polyolefin resins (e.g., polyethylene, polypropylene, etc.), polyolefin copolymer resins (e.g., ethylene-vinyl acetate copolymer, polyethylene-polypropylene copolymer, etc.), vinyl chloride resins (e.g., polyvinyl chloride, ethylene-vinyl chloride copolymer, etc.), vinylidene chloride resins (e.g., polyvinylidene chloride, etc.), polyester resins (e.g., soft polyester, etc.), nylon, vinylon, and other plastic sheets for bags. The flexible sheet is made of, for example, a single-layer or multi-layer sheet made of a thermoplastic resin. Examples of such sheets include laminate films in which a base layer and a heat-sealable sealant layer are laminated. Biaxially oriented films made of polyester resins such as polyethylene terephthalate and polylactic acid, polyamide resins such as nylon, and polyolefin resins such as polypropylene are preferably used as the base layer because of their heat resistance, dimensional stability, and strength. The sealant layer may be a film or extrusion coating layer made of a heat-sealable resin such as low-density polyethylene, high-density polyethylene, linear low-density polyethylene, polypropylene, propylene-ethylene copolymer, ethylene-vinyl acetate copolymer, ionomer resin, or amorphous polyester resin. A gas barrier layer or a reinforcing film made of ethylene-vinyl alcohol or the like may be laminated between the substrate layer and the sealant layer. The substrate layer may be appropriately printed with a trade name or the like.

[0028] (Spout 3) The spout 3 is provided to protrude from the container body 2. The spout 3 is in communication with the storage section 25, and the contents can be poured out and poured (refilled) through the spout 3. In this embodiment, the spout 3 is provided on the top sheet 22 so as to be offset to the left in the width direction, that is, offset to the left of the midpoint (center) in the width direction of the top sheet 22. A cap 5 (see FIG. 4) that is detachably screwed onto the spout 3 can be attached to the spout 3.

[0029] The spout 3 is provided in the first tapered portion R1. Specifically, the center C of the spout 3 is preferably provided at the center (middle) of the first tapered portion R1 in the width direction or to the left of this center. In other words, the spout 3 is preferably disposed close to the first connecting portion 201 that connects the first sealed portion S1, the second sealed portion S2, and the third sealed portion S3. This makes it easier for the spout 3 to be fixed by each sealed portion.

[0030] The spout 3 has a cylindrical spout portion 31 and a flange portion 32 that extends radially outward from the lower end of the spout portion 31. The spout 3 is provided on the top sheet 22 with the flange portion 32 located inside the top sheet 22, i.e., on the housing portion 25 side. Specifically, the spout 3 is a molded product made of polyethylene resin or polypropylene resin, and the flange portion 32 is joined to a sealant layer of the top sheet 22 by heat sealing or the like. This makes it difficult for the spout 3 to fall off the top sheet 22. The flange portion 32 has a substantially square rectangular shape. The flange portion 32 is provided on the first tapered portion R1 so that the two sides of the flange portion 32 on the first connecting portion 201 side are parallel to the second seal portion S2 and the third seal portion S3. This makes it even easier to fix the spout 3. The shape of the flange portion 32 is not limited to a rectangular shape, but may be, for example, a circle, an oval, a polygonal shape other than a rectangle, or any other shape.

[0031] (handle member 4) Carrying member 4 is attached to container body 2 and is a handle for hanging container body 2. Carrying member 4 includes a strap-like carrying piece 41, a first adhesive portion 42 and a second adhesive portion 43 located at both ends of carrying piece 41 and attached to container body 2, and a band (tape)-like cover sheet 44 that covers first adhesive portion 42 and second adhesive portion 43.

[0032] The strap-like carrier strip 41 can be made from synthetic resin, synthetic paper, paper, or a multi-layered sheet of these materials cut into strips or processed into a tape or string shape. Carrying strip 41 is made, for example, from a strong biaxially stretched film, a film uniaxially stretched in the longitudinal direction, or a sheet material formed by laminating these stretched films with other materials. The length of carrier strip 41 (excluding first adhesive portion 42 and second adhesive portion 43) may be approximately 200 mm to 500 mm, preferably 250 mm to 400 mm, so that it can be easily grasped and lifted with the fingers. The width of carrier strip 41 may be 10 mm to 30 mm, and the thickness may be 50 μm to 500 μm. The width or thickness of carrier strip 41 may differ between the center and the ends. An adhesive layer (sticky layer) 45 (see Figure 4) made of a pressure-sensitive adhesive (adhesive) is provided on the inner surface (top sheet 22 side) of the first adhesive portion 42 and the second adhesive portion 43 located at both ends of this carrying piece 41.

[0033] The pouch container 1 also includes a reinforcing cover sheet 44 that covers the first adhesive portion 42 and the second adhesive portion 43. The cover sheet 44 reinforces the first adhesive portion 42 and the second adhesive portion 43 to prevent peeling, and also prevents deformation of the flexible sheet that constitutes the container body 2 in the portion covered by the cover sheet 44. This effectively prevents deformation of the flexible sheet, particularly in the portion sandwiched between the first adhesive portion 42 and the second adhesive portion 43, when the container body 2 is suspended. The cover sheet 44 is formed of a polyolefin resin film such as polyethylene or polypropylene, a polyester film, synthetic paper, or the like. The dimensions of the cover sheet 44 are, for example, a width of 20 mm to 80 mm and a thickness of 30 μm to 200 μm. An adhesive layer (adhesive layer) 46 (see FIG. 4) made of an adhesive is provided on the inner surface of the cover sheet 44 (the side facing the top sheet 22).

[0034] Adhesive layers 45 and 46 are preferably formed from a strong adhesive. This adhesive may be, for example, an acrylic, rubber, or hot-melt adhesive. The adhesive strength (adhesion strength) of adhesive layers 45 and 46 is preferably, for example, 10 N / 25 mm or more (measured by "180-degree peel adhesion strength measurement" in accordance with JIS Z 0237). Adhesive layers 45 and 46 may be formed from the same type of adhesive or different types of adhesive.

[0035] The pouch container 1 is provided with a carrying member 4 for suspending the container body 2. This allows the container body 2 to be carried and the contents to be poured out while being suspended. Therefore, even if the container body 2 has a large capacity, it is easy to carry and the contents to be poured out.

[0036] The carrying piece 4 is adhered to the container body 2. For example, the carrying piece 41, which has a pre-coated adhesive surface protected by a release paper, can be easily attached to the container body 2 with the spout 3 attached by peeling off the release paper and attaching it to a predetermined location on the container body 2. Another possible method for attaching the carrying piece 41 to the container body 2 is to thermally bond the strap-like member to the predetermined location on the container body 2. However, the strong biaxially oriented films used as the base material (surface) of the container body 2, such as biaxially oriented polyethylene terephthalate film or biaxially oriented polyamide film, have relatively low thermal adhesive properties. Therefore, attaching the carrying piece 41 to the surface of the container body 2 after bag production by thermal bonding would damage the container body 2 itself, making it undesirable. Therefore, attaching the carrying piece 41 with an adhesive as described above is preferable because it allows for easy attachment of the carrying piece 41 without damaging the container body 2 itself.

[0037] After attaching carrying piece 41 to container body 2, cover sheet 44 may be attached to cover first adhesive portion 42 and second adhesive portion 43. Alternatively, cover sheet 44 may be attached to carrying piece 41 in advance to create carrying member 4 in which the adhesive is protected with release paper, and then the release paper may be peeled off to attach carrying piece 41 together with cover sheet 44 to container body 2.

[0038] In this embodiment, the handhold member 4 is adhered to the top sheet 22. Specifically, the first adhesive portion 42 and the second adhesive portion 43 of the handhold member 4 are aligned in a row in the width direction and adhered symmetrically to the center portion R3 of the top sheet 22.

[0039] The carrying member 4 may be made of the same material as the container body 2, or a different material. The carrying member 4 may be transparent or colored, such as white. The carrying piece 41 or cover sheet 44 that make up the carrying member 4 may be appropriately printed with display information such as the product name. When the container body 2 and the carrying member 4 are made of different materials, the strength of the carrying member 4 can be adjusted by changing the material of the carrying member 4 depending on the capacity of the container body 2.

[0040] [Pouch container 1 usage status] 4001 in FIG. 4 is a perspective view showing the pouch container 1 in use, and 4002 in FIG. 4 is a cross-sectional view taken along line AA of 4001 in FIG. 4. When the container body 2 containing the contents is suspended, an upward force F is applied to the top sheet 22 by the handle 4. This pulls the central portion R3 of the top sheet 22 upward, preventing the top sheet 22 from deforming into a downward concave shape. In addition, the upward pull of the central portion R3 of the top sheet 22 tilts the first tapered portion R1 and the second tapered portion R2, holding the spout 3 at an angle that makes it easy to pour the contents. This stabilizes the angle of the spout 3, making it easier to pour the contents.

[0041] As described above, the pouch container 1 includes a handle 4 for suspending the container body 2, allowing the container body 2 to be carried and the contents to be poured out while being suspended. Therefore, even when the container body 2 has a large capacity, it is easy to carry and pour out the contents. Additionally, in the pouch container 1, the spout 3 is located on one side of the top sheet 22 in the width direction, so that the spout 3 is provided adjacent to each of the second sealed portion S2 and the third sealed portion S3. Therefore, deformation of the top sheet 22 at the portion where the spout 3 is attached is suppressed by the sealed portion, stabilizing the shape and facilitating the pouring out of the contents. Therefore, this embodiment provides a pouch container 1 that is easy to carry and pour out of.

[0042] [Modification of pouch container] (First Modification) Fig. 5 is a perspective view showing a pouch container 1A, which is a modified example of the pouch container 1 shown in Fig. 4. The pouch container 1A is identical to the above-described pouch container 1 in terms of the container body 2 and spout 3. The pouch container 1A differs from the pouch container 1 mainly in that it is provided with a first carrying member 4A and a second carrying member 4B as carrying members.

[0043] As shown in Figure 5, the first handling element 4A is adhered to the front sheet 21a. The second handling element 4B is adhered to the back sheet 21b. Specifically, the first adhesive portion 42 of the first handling element 4A is adhered below the bent portion 221 of the second seal portion S2, and the second adhesive portion 43 of the first handling element 4A is adhered below the bent portion 222 of the second seal portion S2. The first adhesive portion 42 of the second handling element 4B is adhered below the bent portion 223 of the third seal portion S3, and the second adhesive portion 43 of the second handling element 4B is adhered below the bent portion 224 of the third seal portion S3.

[0044] The first adhesive portion 42 and the second adhesive portion 43 only need to be located near the bottom of the bent portions 221-224, and may be located within a range of, for example, ±20 mm in the width direction from the bottom of the bent portions 221-224. Furthermore, the vertical distance d2 between the first seal portion S1 and the cover sheet 44 (the first adhesive portion 42 and the second adhesive portion 43) is preferably no more than one-third of the height dimension H of the container body 2 excluding the widths of the first seal portion S1 and the fourth seal portion S4 on both the top and bottom. This allows the container body 2 to be stably suspended by the carrying member 4A and the carrying member 4B.

[0045] In pouch container 1A, container body 2 is shaped like a rectangular pillar with bent portions 221-224 protruding outward when the contents are stored therein, and when this rectangular pillar-shaped container body 2 is lifted together with first and second carrying members 4A, 4B, the areas near each of bent portions 221-224 are pulled upward and toward the central axis of container body 2. As a result, bent portions 221-224 are pressed toward the inside of storage section 25, but because bent portions 221-224 are angular and have a shape that makes them less likely to deform inward, deformation of top sheet 22 is suppressed.

[0046] In the first handling member 4A, the first adhesive portion 42 may be located outside (on the left side) the bent portion 221, and the second adhesive portion 43 may be located outside (on the right side) the bent portion 222. Similarly, in the second handling member 4B, the first adhesive portion 42 may be located outside (on the left side) the bent portion 223, and the second adhesive portion 43 may be located outside (on the right side) the bent portion 224. Even in this case, a force is applied to the container body 2 inward in the width direction while the container body 2 is suspended, and downward concave deformation of the top sheet 22 is suppressed.

[0047] (Second Modification) Fig. 6 is a perspective view showing a state in use of pouch container 1B, which is another modified example of the pouch container 1 shown in Fig. 4. Pouch container 1B is identical to the above-described pouch containers 1 and 1A in terms of the container body 2 and spout 3. Pouch container 1B differs from pouch container 1 mainly in that it has a first carrying member 4A and a second carrying member 4B as carrying members, and these carrying members 4A and 4B are located toward the spout 3.

[0048] As shown in Figure 6, the first handling element 4A is adhered to the front sheet 21a. The second handling element 4B is adhered to the back sheet 21b. Specifically, the first adhesive portion 42 of the first handling element 4A is adhered below the first tapered portion R1, and the second adhesive portion 43 of the first handling element 4A is adhered below the center portion R3. The first adhesive portion 42 of the second handling element 4B is adhered below the first tapered portion R1, and the second adhesive portion 43 of the second handling element 4B is adhered below the bent portion 224 of the center portion R3.

[0049] In pouch container 1B, when container body 2 containing the contents is suspended, container body 2 tilts to the side opposite to the side where spout 3 is provided. This makes it difficult for the contents to overflow from spout 3. When pouring the contents, the bottom side of container body 2 opposite spout 3 can be lifted by hand to adjust the angle of spout 3, making it easier to pour the contents out.

[0050] The pouch container 1B is an example of a configuration that does not include a reinforcing cover sheet 44 that covers the first adhesive portion 42 and the second adhesive portion 43. As such, the cover sheet 44 is not essential and can be omitted as appropriate depending on the capacity of the container body 2, the weight of the contents, etc.

[0051] [Embodiment 2] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the previous embodiment, and the description thereof will not be repeated.

[0052] [Configuration of pouch container 11] Fig. 7 is a plan view showing the front side of the pouch container 11 according to embodiment 2 of the present invention. Fig. 8 is a plan view showing the back side of the pouch container 11 shown in Fig. 7. Figs. 7 and 8 show the pouch container 11 in a folded state.

[0053] 7 and 8, the pouch container 11 includes a container body 2 formed from a flexible sheet having an annular body portion 21, a top sheet 220 (first end sheet portion), and a bottom sheet (second end sheet portion) 23, a spout 30 attached to the joint between the upper end of the front sheet 21a of the body portion and the top sheet 220, and a handle 40 attached to the front sheet 21a of the body portion 21. The pouch container 11 is generally identical to the pouch container 1 described in the above embodiment, except for the shapes, positions, etc. of the top sheet 220, spout 30, and handle 40. Therefore, the following description will mainly focus on the differences from the pouch container 1.

[0054] 7 and 8. However, the pouch container 11 is not limited to being used in an orientation in which the top sheet 220 is positioned above and the bottom sheet 23 is positioned below. For example, the pouch container 11 can be used in an orientation in which the bottom sheet 23 does not support itself, that is, in which the top sheet 220 and the bottom sheet 23 are positioned in the left-right direction.

[0055] (Top sheet 220) The top sheet 220 is joined to the upper end (one end) of the body 21. The top sheet 220 is curved so as to taper outward in the width direction, and has a generally spindle shape overall. When the container body 2 is folded, the top sheet 220 is folded between the front sheet 21a and the back sheet 21b, and is folded in half so as to form a woven line 221 that runs along the width direction of the pouch container 11.

[0056] (Spout 30) The spout 30 is attached to the first seal portion S1. The flange portion 32 of the spout 30 may be, for example, boat-shaped, and is fixed to the second seal portion (seal portion) S2 by heat welding the boat-shaped flange portion 32 while it is sandwiched between the front sheet 21a and the top sheet 220. Specifically, the horizontal cross section of the flange portion 32 is boat-shaped and thick, and the side peripheral surfaces of this boat-shaped flange portion 32 are heat-welded to the front sheet 21a and the top sheet 220.

[0057] In addition, the second sealed portion S2 and the third sealed portion S3 may be located at different heights in the vertical direction in the container body 2. For example, by adjusting the size, folding position, etc. of the top sheet 220, the second sealed portion S2 where the spout 30 is provided may be located higher than the third sealed portion S3. In addition, the shape of the top sheet 220 is not limited to the above-mentioned approximately spindle shape, and may be the same shape as the bottom sheet 23. Furthermore, the shapes of the front sheet 21a and the back sheet 21b may be different from each other.

[0058] (handle member 40) The carrying member 40 is adhered to the front sheet 21a. The carrying member 40 has a strip-like (tape-like) cover sheet 44, which covers both ends of the carrying piece 41 (first adhesive portion 42 and second adhesive portion 43). Using such a strip-like (wide strip-like) cover sheet 44 improves the adhesiveness of the carrying member 40. The first adhesive portion 42 and second adhesive portion 43 of the carrying member 40 are adhered to the front sheet 21a in a line symmetrically in the width direction. Specifically, of three imaginary lines extending vertically so as to divide the width dimension W of the container body 2 into approximately four equal parts in the width direction, the leftmost line segment is defined as the third line segment L3, and the rightmost line segment is defined as the fourth line segment L4. In this case, the carrying member 40 is adhered so that the first adhesive portion 42 overlaps the third line segment L3, and the second adhesive portion 43 overlaps the fourth line segment L4. The positions of the third line segment L3 and the fourth line segment L4 are not limited to those described above, and it is sufficient that the widthwise distance d3 between the third line segment L3 and the first seal portion S1 on the left side, and the widthwise distance d3 between the fourth line segment L4 and the first seal portion S1 on the right side are both between 1 / 6 and 1 / 3 of the width W of the container body 2. The handle 40 is biased toward the side of the front sheet 21a where the spout 30 is provided in the vertical direction, i.e., the second seal portion S2 side, and is adhered to the front sheet 21a.

[0059] In the illustrated example, the carrying piece 41 is oriented downward relative to the first adhesive portion 42 and the second adhesive portion 43, i.e., the carrying piece 40 is attached to the front sheet 21a in an orientation in which the carrying piece 41 hangs downward. However, the carrying piece 40 may also be attached to the front sheet 21a in an orientation in which the carrying piece 41 is oriented upward relative to the first adhesive portion 42 and the second adhesive portion 43.

[0060] Furthermore, when bends 221-224 are formed in the second sealed portion S2 and the third sealed portion S3, as in the top sheet 22 of the pouch container 1 described in the above embodiment, an imaginary line segment extending vertically through bend 221 may be defined as the third line segment L3, and an imaginary line segment extending vertically through bend 222 may be defined as the fourth line segment L4. Even when the third line segment L3 and the fourth line segment L4 are defined in this manner, it is sufficient that the first adhesive portion 42 is positioned at a position overlapping with the third line segment L3, and the second adhesive portion 43 is positioned at a position overlapping with the fourth line segment L4. In this case, the widthwise distance between the third line segment L3 and the left-side first sealed portion S1 and the widthwise distance between the fourth line segment L4 and the right-side first sealed portion S1 are both preferably between 1 / 6 and 1 / 3 of the width dimension W of the container body 2.

[0061] [Usage state of pouch container 11] FIG. 9 is a perspective view showing the pouch container 11 in use. When the container body 2 containing the contents is suspended, the front sheet 21a is pulled upward. In the pouch container 11, the handle 40 is adhered to the side of the front sheet 21a where the spout 30 is provided, so when the container body 2 is tilted during pouring, the contents are less likely to spill over the spout 30. Furthermore, because the handle 40 is biased toward the side of the front sheet 21a where the spout 30 is provided, the container body 2 tilts to the side opposite the side where the spout 30 is provided. This makes it even more difficult for the contents to spill over the spout 30.

[0062] As described above, the pouch container 11 includes a handle 40 for suspending the container body 2, allowing the container body 2 to be carried and the contents to be poured out while being suspended. Therefore, even when the container body 2 has a large capacity, it is easy to carry and the contents to be poured out. In addition, in the pouch container 11, the handle 40 is bonded to the front sheet 21a side where the spout 30 is provided, so that the contents are less likely to spill out of the spout 30 when the container body 2 is tilted during pouring. Therefore, according to this embodiment, a pouch container 11 suitable for large capacity can be realized.

[0063] [Modification of pouch container] (First Modification) Fig. 10 is a perspective view showing a pouch container 11A, which is a modified example of the pouch container 11 shown in Fig. 9. Pouch container 11A is identical to pouch container 11 in terms of the container body 2 and spout 30. Pouch container 11A differs from pouch container 11 mainly in that it is provided with a first carrying member 40A and a second carrying member 40B as carrying members.

[0064] As shown in Figure 10, the first adhesive portion 42 and the second adhesive portion 43 of the first handling element 40A are positioned so as to contact or overlap the third line segment L3. The first adhesive portion 42 and the second adhesive portion 43 of the second handling element 40B are also bonded so as to contact or overlap the fourth line segment L4. The first and second handling elements 40A and 40B are bonded symmetrically, biased toward the side where the spout 30 is provided. The first adhesive portion 42 and the second adhesive portion 43 may be positioned near the third line segment L3 or the fourth line segment L4.

[0065] When pouring the contents into the pouch container 11A, with the container body 2 tilted toward the spout 30, a force is applied inward in the width direction to the center portion R4 of the front sheet 21a, which is sandwiched between the third line segment L3 and the fourth line segment L4, preventing the front sheet 21a on the side where the spout 30 is provided from deforming into a downward concave shape. This stabilizes the angle of the spout 30, making it easier to pour the contents.

[0066] (Second Modification) Fig. 11 is a perspective view showing a state in use of a pouch container 11B, which is another variation of the pouch container 11 shown in Fig. 9. Pouch container 11B is identical to the above-described pouch containers 11 and 11A in terms of the container body 2 and spout 30. Pouch container 11B differs from pouch containers 11 and 11A mainly in that it has a first handle 40A and a second handle 40B as handle members, and these handle members 40A and 40B are attached outside the third line segment L3 and the fourth line segment L4.

[0067] The cover sheet 44 of the first carrying member 40A extends longitudinally in the vertical direction of the container body 2 and is adhered along the first seal S1 on the left side of the container body 2 of the pouch container 11B. The cover sheet 44 of the second carrying member 40B extends longitudinally in the vertical direction of the container body 2 and is adhered along the first seal S1 on the right side of the container body 2. Furthermore, the first and second carrying members 40A and 40B are biased toward the side where the spout 30 is provided and are adhered symmetrically.

[0068] In the pouch container 11B, when the container body 2 is tilted toward the spout 30 to pour out the contents, a force is applied to the front sheet 21a inward in the width direction, which prevents the front sheet 21a on the side where the spout 30 is provided from deforming into a concave downward shape. This stabilizes the angle of the spout 30, making it easier to pour out the contents.

[0069] In this way, the first handling member 40A may be adhered to the front sheet 21a so that the first adhesive region 42 and the second adhesive region 43 overlap in the area between the first seal portion S1 on the left side and the third line segment L3. Similarly, the second handling member 40B may be adhered to the front sheet 21a so that the first adhesive region 42 and the second adhesive region 43 overlap in the area between the first seal portion S1 on the right side and the fourth line segment L4.

[0070] 〔summary〕 A pouch container according to one embodiment of the present invention includes a container body having a cylindrical body portion including a first body sheet portion and a second body sheet portion opposite the first body sheet portion, a first end sheet portion covering one end of the body portion, and a second end sheet portion covering the other end of the body portion, a spout located on one side of the width of the container body and provided on the first end sheet portion, and a handle member adhered to the container body for hanging the container body.

[0071] In this configuration, the pouch container includes a handle for suspending the container body, allowing the container body to be carried and the contents to be poured out while being suspended. Therefore, even when the container body has a large capacity (e.g., between 3 and 15 liters), it is easy to carry and pour out the contents. Additionally, in this configuration, the spouts are located on one side of the first end sheet portion in the width direction, so that the spouts are provided adjacent to the connection between the first body sheet portion and the first end sheet portion and the connection between the second body sheet portion and the first end sheet portion. This prevents deformation of the first end sheet portion at the spout attachment point, stabilizing its shape and facilitating the pouring of the contents. Therefore, this configuration allows for a pouch container that is easy to carry and pour out.

[0072] In a pouch container according to one embodiment of the present invention, the first end surface sheet portion may have a tapered portion at the end of the one side that tapers toward the one side, and the spout may be provided in the tapered portion.

[0073] According to this configuration, deformation of the first end surface sheet portion where the spout is attached is suppressed and the shape is stabilized, making it easier to fix the spout.

[0074] In the pouch container according to one aspect of the present invention, the handle may be adhered to the first end sheet portion.

[0075] In this configuration, the first end surface sheet portion is prevented from being deformed into a concave shape downward when pulled upward, thereby stabilizing the angle of the spout and making it easier to pour the contents. A pouch container according to one embodiment of the present invention may include a pair of carrying members, one of which may be adhered to the first body sheet portion and the other of which may be adhered to the second body sheet portion.

[0076] According to this configuration, the container body can be stably suspended by the pair of carrying members.

[0077] In a pouch container according to one embodiment of the present invention, the attachment positions of the pair of handle members to the first body sheet portion or the second body sheet portion may be biased toward the side where the spout is provided in the width direction.

[0078] In this configuration, when the container body is suspended, the container body tilts to the side opposite to the side where the spout is provided, making it difficult for the contents to spill over the spout.

[0079] A pouch container according to one embodiment of the present invention includes a container body having a cylindrical body portion including a first body sheet portion and a second body sheet portion opposite the first body sheet portion, a first end sheet portion covering one end of the body portion, and a second end sheet portion covering the other end of the body portion, a spout provided at the seal portion between the first body sheet portion and the first end sheet portion, and a carrying member adhered to the first body sheet portion for hanging the container body.

[0080] In this configuration, the pouch container is provided with a handle for suspending the container body, allowing the container body to be carried and the contents to be poured out while being suspended. Therefore, even when the container body is large-capacity, it is easy to carry and pour out the contents. In addition, in this configuration, the handle is attached to the first body sheet portion where the spout is provided, making it difficult for the contents to spill out of the spout when the container body is tilted during pouring. Therefore, this configuration makes it possible to realize a pouch container suitable for large-capacity use.

[0081] In a pouch container according to one embodiment of the present invention, the attachment position of the handle member to the first body sheet may be biased toward the side of the first body sheet portion where the spout is provided.

[0082] According to this configuration, when the container body is suspended, the container body tilts to the side opposite to the side on which the spout is provided, and therefore, according to this configuration, the contents are less likely to overflow from the spout. [Explanation of symbols]
