Description

  The present invention relates to a pouch.

  2. Description of the Related Art Conventionally, refill pouches, retort pouches, and the like contain contents including liquids and viscous bodies. In such a pouch, since it is necessary to transfer the contents to a refill container or cooking utensil, it is required to leave the contents without leaving the pouch.

  However, there is a problem in that the contents cannot be completely removed from the pouch and a part of the contents remains in the pouch. For this reason, in order to make it difficult for the contents to remain in the pouch, a technique for forming a concavo-convex shape on a part or all of the inner surface of the pouch has been developed (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 2002-362591

[First Embodiment]
Hereinafter, a pouch according to a first embodiment of the present invention will be described with reference to the drawings. In this specification, terms such as “film” and “sheet” are not distinguished from each other only based on the difference in designation. Therefore, for example, “film” is used to include a member that is also called a sheet. FIG. 1 is a front view of the pouch according to the present embodiment, FIG. 2 is a view of the pouch shown in FIG. 1 viewed from the bottom side, and FIG. 3 is a flexible film used for the pouch according to the present embodiment. FIG. FIG. 4 is a front view of another pouch according to the present embodiment, and FIG. 5 is a view when the contents are completely taken out from the pouch according to the present embodiment.

<< Pouch >>
The pouch 10-1 shown in FIG. 1 has a storage space for storing contents. The contents are not particularly limited, and examples include contents containing liquids and viscous bodies. The contents include shampoos, conditioners, body soaps, household liquid detergents, other liquid seasonings, edible oils, various beverages, etc. And contents used by transferring to other containers such as bottles. However, the contents are not limited to these.

  As shown in FIGS. 1 and 2, the pouch 10-1 has a front film 11, a back film 12, and a bottom film 13. The pouch 10-1 has an upper edge 10A, a lower edge 10B, and a first side edge 10C and a second side edge 10D extending between the upper edge 10A and the lower edge 10B. The second side edge 10D is an edge opposite to the first side edge 10C. In the present specification, the positions of “upper”, “lower”, “side”, and “bottom” mean positions in a state where a gusset folding portion, which will be described later, is expanded and the pouch is self-supporting.

  The pouch 10-1 includes a main body portion 14 that can accommodate the contents, and a spout portion 15 for taking out the contents from the main body portion 14. In FIG. 1, the main body part 14 and the spout part 15 are made of the same member (a flexible film 30 described later), but the spout part is made of a member different from the main part, such as a spout. May be. In FIG. 1, the main body portion 14 is a portion other than the spout portion 15.

<Outlet section>
The spout portion 15 shown in FIG. 1 is formed on the upper edge 10A. Specifically, the spout portion 15 is formed so as to protrude in the height direction DR1 of the pouch 10-1 at the center of the upper edge 10A. The tip 15A of the spout part 15 is linear.

  In the spout part 15 shown in FIG. 1, the center line CL of the spout part 15 is parallel to the virtual line IL orthogonal to the lower edge 10B. It is assumed that the imaginary line IL is drawn at a place other than the corner that is the boundary between the first side edge 10C and the second side edge 10D in the lower edge 10B.

  The center line of the spout portion is a virtual line, and can be determined as follows if the spout portion is not sealed as shown in FIG. When the tip of the outer edge of the spout portion is linear, the center line of the spout portion can be determined by drawing a bisector of the length of the tip. When the tip of the outer edge of the spout portion is square, the center line of the spout portion can be determined by drawing a bisector of the angle of the tip. In addition, when the tip of the outer edge of the spout portion is rounded such as an arc shape, two virtual lines extending both side edges constituting the outer edge of the spout portion are drawn, and the virtual lines intersect each other The center line of the spout portion can be determined by drawing a bisector of the angle of the location.

  Moreover, when the spout part is sealed, it can be determined as follows. When the tip of the inner edge of the seal portion of the spout portion is linear, the center line of the spout portion can be determined by drawing a bisector of the length of the tip. Further, when the tip of the seal portion of the spout portion is square, the center line of the spout portion can be determined by drawing a bisector of the angle of the tip. In addition, when the tip of the inner edge of the seal portion of the spout portion is rounded, such as an arc, draw two imaginary lines extending both side edges constituting the inner edge of the seal portion of the spout portion, The center line of the spout can be determined by drawing a bisector of the angle where the virtual lines intersect.

  The pouch 10-1 includes a gusset folding portion 16 on the lower edge 10B side. By providing the gusset folding part 16, the pouch 10-1 can be made independent. Moreover, since the accommodation space can be increased, more contents can be accommodated.

<Guset insert part>
The gusset folding part 16 is a bottom surface inserted inside between the bottom part 11A of the front face film 11, the bottom part 12A of the back face film 12, and the bottom part 11A of the front face film 11 and the bottom part 12A of the back face film 12. And a film 13. The gusset folding part 16 is formed along the direction in which the lower edge 10B extends.

  The ratio of the width W1 (see FIG. 1) of the gusset folding part 16 to the height of the pouch 10-1 is preferably 0.1 or more and 0.5 or less. If the ratio is 0.1 or more, more contents can be accommodated. Moreover, if the said ratio is 0.5 or less, when making the pouch 10-1 self-support after opening, the pouch 10-1 can be made to stand stably. The width W1 of the gusset fold 16 is the length of the gusset fold 16 in the height direction DR1. Specifically, it is the length from the lower edge 10B to the folding line 16A. When the width of the gusset folding part is not constant, the width of the gusset folding part is the shortest value. The lower limit of the ratio is more preferably 0.2 or more, and the upper limit of the ratio is more preferably 0.3 or less. The width W1 of the gusset folding part 16 may be 20 mm or more and 80 mm or less.

  The pouch 10-1 includes a first side seal portion 17, a second side seal portion 18, a first bottom seal portion 19, a second bottom seal portion 20, and an auxiliary seal portion 21. Moreover, the 1st embossing part 22 is formed in the pouch 10-1. In FIG. 1, the upper part of the pouch 10-1 is open, but after the contents are filled into the accommodation space, the upper seal is enclosed by the upper edge 10A and the two-dot chain line in FIG. An upper seal portion is formed in the portion forming region R1, and the pouch 10 is sealed.

<First side seal part and second side seal part>
The first side seal portion 17 is a portion where the front film 11 and the back film 12 are joined to each other at the end on the first side edge 10C side, and the second side seal portion 18 is the second side. At the end on the edge 10D side, the front film 11 and the back film 12 are joined together. The 1st side part seal part 17 and the 2nd side part seal part 18 are formed by heat-sealing the flexible films 30 mentioned later.

  The outer edge 17A of the first side seal portion 17 is a first side edge 10C, and the outer edge 18A of the second side seal portion 18 is a second side edge 10D.

  The width W2 (see FIG. 1) of the first side seal portion 17 and the width W3 (see FIG. 3) of the second side seal portion 18 are preferably, for example, 5 mm or more and 15 mm or less, respectively. If the width W2 of the first side seal portion 17 and the width W3 of the second side seal portion 18 are each 5 mm or more, the first side seal portion 17 and the second side seal portion 18 are surely sealed. If it is 15 mm or less, it is possible to secure a wider accommodation space. In this specification, “width” in each seal portion means a length in a direction orthogonal to the extending direction of the seal portion. In addition, when the width | variety of a seal part is not constant, let the width | variety of a seal part be the shortest value among the length of the direction orthogonal to the direction where a seal part is extended.

<First bottom seal portion and second bottom seal portion>
The first bottom seal part 19 is a part where a part of the bottom part 11A of the front surface film 11 and a part of the bottom film 13 in the gusset folding part 16 are joined together, and the second bottom seal part 20 is a gusset folding part. This is a part where a part of the bottom 12A of the back film 12 and a part of the bottom film 13 are joined to each other in the part 16. The first bottom seal portion 19 is formed by heat-sealing the front film 11 and the bottom film 13, and the second bottom seal portion 20 is heat-sealing the back film 12 and the bottom film 13. Is formed.

<Auxiliary seal part>
The auxiliary seal portions 21 are formed at both edges on the width direction DR2 side at the bottom of the pouch 10-1. The auxiliary seal portion 21 is a portion where the front film 11 and the back film 12 are joined to each other. The auxiliary seal portion 21 is formed by heat-sealing the front film 11 and the back film 12 through a notch provided in the bottom film 13. From the viewpoint of expanding the gusset folding portion when filling the content space into the accommodation space, it is necessary that the first bottom seal portion and the second bottom seal portion be separated from each other in the center portion of the bottom of the pouch. When the seal portion and the second bottom seal portion are completely separated from each other, the first bottom seal portion and the second bottom seal portion cannot withstand the weight of the contents when the storage space is filled with the contents, and the first The space between the bottom seal portion and the second bottom seal portion may open, making it difficult for the pouch to stand on its own. Moreover, since the base material layers mentioned later cannot be heat-sealed, the 1st bottom part seal part and 2nd bottom part seal part in which base material layers are facing each other cannot be heat-sealed as it is. For this reason, only the both ends of the 1st bottom part seal part 19 and the 2nd bottom part seal part 20 are joined by forming auxiliary seal part 21. Therefore, when filling the contents, the pouch 10-1 can be made to stand by itself stably without inhibiting the spread of the bottom film 13.

<First embossed part>
The first embossed portion 22 is formed at least in each of the first bottom seal portion 19 and the second bottom seal portion 20 and extends from the lower edge 10B toward the spout portion 15 so as to overlap each other. The first embossed portion 22 shown in FIG. 1 extends to the upper edge 10A. However, the first embossed portion 22 needs to extend to the upper edge 10A as long as it is formed on at least the first bottom seal portion 19 and the second bottom seal portion 20. There is no. The first embossed portion 22 can be formed by thermal ruled line processing.

  The first embossed portion 22 shown in FIG. 1 is located on the center line CL of the spout portion 15. Since the first embossed portion 22 is positioned on the center line CL of the spout portion 15, the pouch 10-1 can be folded in two at the position of the center line CL of the spout portion 15. It is easy to put out. However, the 1st embossing part 22 may exist in the position which remove | deviated from the centerline CL of the spout part 15. FIG.

  In the pouch 10-1, as shown in FIG. 2, the first embossed portion 22 formed on the first bottom seal portion 19 and the first embossed portion 22 formed on the second bottom seal portion 20 are in the same direction. It is recessed. Specifically, in FIG. 2, the first embossed portion 22 formed on the first bottom seal portion 19 is a concave portion 22B, and the first embossed portion 22 formed on the second bottom seal portion 20 is convex. Since the first embossed portion 22 formed on the first bottom seal portion 19 and the first embossed portion 22 formed on the second bottom seal portion 20 are formed from the outer surface 11B of the front surface film 11, It is recessed in the direction DR3 toward the outer surface 12B of the film 12. As described above, the first embossed portion 22 formed on the first bottom seal portion 19 and the first embossed portion 22 formed on the second bottom seal portion 20 are recessed in the same direction, so that the pouch 10-1 is opened. The front film 11 can be folded in half. Note that when the pouch 10-1 is folded at the position of the first embossed portion 22, the pouch 10-1 is folded on the recessed side from the viewpoint of ease of folding. Moreover, the 1st embossed part formed in the 1st bottom part seal part and the 1st embossed part formed in the 2nd bottom part seal part may protrude in the same direction. Specifically, the first embossed part formed on the first bottom seal part may be a convex part, and the first embossed part formed on the second bottom seal part may be a concave part. Can be folded in half.

  In the present specification, the “embossed portion” may be a convex portion or a concave portion. In addition, the “convex portion” in the present embodiment and the second embodiment means that the outer surface of the front film or the back film protrudes and the inner surface is recessed and the bottom surface at the place where the bottom seal portion exists. It means the part where the inner surface of the film protrudes and the outer surface is recessed, and in the part where the bottom seal part does not exist, it means the part where the outer surface of the front film or the back film protrudes and the inner surface is recessed To do. In addition, the “recessed portion” means that the outer surface of the front film or the back film is recessed and the inner surface protrudes, and the inner surface of the bottom film is recessed and the outer surface protrudes where the bottom seal portion exists. In the place where the bottom seal portion does not exist, the outer surface of the front film or the back film is recessed and the inner surface protrudes. The inner surface of the bottom film is a surface on the accommodation space side, and the outer surface of the bottom film is a surface opposite to the inner surface of the bottom film.

  The width W4 (see FIG. 1) of the first embossed portion 22 is preferably 2 mm or more and 10 mm or less. If the width W4 of the first embossed portion 22 is 2 mm or more, it can be a trigger for folding, and if the width W4 is 10 mm or less, it can be folded in half. The upper limit of the width of the first embossed portion 22 is more preferably 5 mm or less from the viewpoint that it can be surely folded in half.

  The length of the first embossed portion 22 is preferably 5 mm or more. The length of the first embossed portion 22 is the length of the pouch 10 in the height direction DR1. If the length of the 1st embossed part 22 is 5 mm or more, the pouch 10-1 can be easily folded in two.

  The cross section of the first embossed portion 22 shown in FIG. 2 is trapezoidal, but the shape of the first embossed portion 22 is not particularly limited. For example, the cross section is semicircular, semielliptical, V-shaped. It may be in the shape.

  The pouch 10-1 is composed of a flexible film 30. That is, the front film 11, the back film 12, and the bottom film 13 are composed of the flexible film 30. As shown in FIG. 3, the flexible film 30 includes at least a base material layer 31 and a sealant layer 32 in this order. The flexible film 30 shown in FIG. 3 further includes a bonding layer 33, an intermediate layer 34, and a bonding layer 35 between the base material layer 31 and the sealant layer 32. The “soft film” in this specification means a foldable film.

  The thickness of the base material layer 31 can be, for example, 5 μm or more and 30 μm or less. If the thickness of the base material layer 31 is 5 μm or more, the self-supporting property of the pouch 10-1 can be improved, and if it is 30 μm or less, it can be easily folded. The thickness of the base material layer 31 shall be obtained as an arithmetic average value of the measured thickness by randomly measuring the thickness at 10 locations from a cross-sectional photograph of the base material layer taken using an optical microscope. In the pouch, the base material layer 31 is disposed on the outermost side.

<Sealant layer>
The sealant layer 32 is provided in order to seal the accommodation space of the pouch 10-1 by overlapping and heat-sealing two flexible films. For this reason, in the pouch 10-1, it arrange | positions so that the sealant layer 32 may become the accommodation space side most.

  The sealant layer 32 may be any material that can be melted by heat and fused the opposing flexible films 30 to each other. For example, low-density polyethylene, medium-density polyethylene, high-density polyethylene, linear (linear) Low density polyethylene, ethylene / α-olefin copolymer polymerized using metallocene catalyst (single site catalyst), polypropylene, ethylene / vinyl acetate copolymer, ionomer resin, ethylene-ethyl acrylate copolymer, ethylene- Polyolefin resins such as acrylic acid copolymer, ethylene-methacrylic acid copolymer, ethylene-propylene copolymer, methylpentene polymer, polyethylene or polypropylene are unsaturated such as acrylic acid, methacrylic acid, maleic anhydride, fumaric acid, etc. Acid-modified polyolefin modified with carboxylic acid Resins.

  The thickness of the sealant layer 32 can be 10 μm or more and 200 μm or less. If the thickness of the sealant layer 32 is 200 μm or less, it can be easily folded. The lower limit of the thickness of the sealant layer 32 is more preferably 30 μm or more and 70 μm or more from the viewpoint of further improving the self-supporting property of the pouch 10-1, and the upper limit of the thickness of the sealant layer 32 is more preferable. Is more preferably 150 μm or less from the viewpoint of easier folding. The thickness of the sealant layer 32 can be measured by the same method as the thickness of the base material layer 31.

For example, a polyvinyl acetate adhesive, a polyacrylate adhesive, a cyanoacrylate adhesive Agents, ethylene copolymer adhesives, cellulose adhesives, polyester adhesives, polyamide adhesives, amino resin adhesives, epoxy adhesives, polyurethane adhesives, and the like can be used. The polyurethane-based adhesive is a cured product of a polyol compound and an isocyanate compound.

<Intermediate layer>
The intermediate layer 34 is a layer for supplementing various functions required for the pouch 10-1. For example, when the pouch 10-1 contains food as a content, the intermediate layer 34 prevents the permeation of water vapor so that the content can be preserved while preventing alterations such as oxidation of the content. It may have a vapor barrier property and a gas barrier property that prevents permeation of gas such as oxygen gas. Further, since the standing type pouch 10-1 is displayed in a stand-alone state on the product shelf of the sales floor, the intermediate layer 34 is sufficiently resistant to an impact or the like when the pouch 10-1 falls from the product shelf. May have bending resistance and impact resistance. Further, the intermediate layer 34 may have a function of sufficiently improving the concealment so that the contents of the pouch 10-1 are not visible in order to increase the consumer's willingness to purchase.

  In the spout part 15 shown in FIG. 4, the center line CL of the spout part 15 is inclined with respect to the virtual line IL orthogonal to the lower edge 10B. Moreover, the notch parts 15B and 15C are formed in the both sides of the spout part 15, and the spout part 15 becomes the shape which protruded in the neck shape. By adopting such a configuration, when the contents filled in the pouch 10-2 are transferred to a refill container such as a bottle, the tip of the spout portion 15 is cut off and opened, and the spout portion 15 is refilled, for example. Since the contents can be poured out while being inserted into the mouth of the container or the notches 15B and 15C on the side of the spout 15 being applied to the mouth of the refill container, the spout 15 can be stably fixed to the mouth of the refill container, and the contents can be transferred.

  The spout port 15 is provided with an opening start means 41 such as a notch or a notch at a planned opening position in order to cut and open the tip of the spout port 15. In addition, the opening start means 41 is provided with an opening guide portion 42 for stabilizing the cutting direction when the tip of the spout portion 15 is cut off. As the opening guide part 42, for example, a half-cut line by laser light irradiation or the like, or a method of laminating a uniaxially stretched film in a flexible film (in this case, the uniaxially stretched film has its stretching direction opened at the spout part. Used to match the direction).

  When providing a half-cut line as the opening guide part 42, it is not limited to a straight half-cut line, and may be an intermittent half-cut line such as a perforation. In addition, the number of such half-cut lines may be one, but assuming that the tearing direction is deviated, one or two half-cut lines are provided on both sides of the center half-cut line. You may provide in parallel.

  Also in the pouch 10-2, a first embossed portion 22 is formed at least in each of the first bottom seal portion 19 and the second bottom seal portion 20. The first embossed portion 22 of the pouch 10-2 is the same as the first embossed portion 22 of the pouch 10-1, but the center line CL of the spout portion 15 of the pouch 10-2 is a virtual line orthogonal to the lower edge 10B. Since it is inclined with respect to IL, the first embossed portion 22 of the pouch 10-2 is also inclined with respect to the virtual line IL.

  When taking out the contents from the pouch 10-1, the contents are taken out from the spout part 15 to some extent, and then the pouch 10-1 is folded in two on the surface film 11 side at the position of the first embossed part 22. To do. In addition, since the 1st embossing part 22 exists on the centerline CL of the spout part 15 parallel to the virtual line IL orthogonal to the lower edge 10B, the pouch 10-1 is placed at the position of the 1st embossing part 22. When folded in half on the front film 11 side, the broken line is parallel to the imaginary line IL. Then, as shown in FIG. 5, the pouch 10-1 is held with one hand and the folded pouch 10-1 is sandwiched between the index finger and middle finger of the other hand or between the thumb and index finger. Then, the other hand is slid toward the spout portion 15. Thereby, the contents can be taken out from the spout part 15. Also in the pouch 10-2, the pouch 10-1 is folded into two on the front film 11 side at the position of the first embossed portion 22 in the same manner as the pouch 10-1, but the first embossed portion 22 has a lower edge. Since it exists on the center line CL of the spout part 15 inclined with respect to the virtual line IL orthogonal to 10B, the pouch 10-2 is placed on the front film 11 side at the position of the first embossed part 22. When folded, the broken line is inclined with respect to the virtual line IL.

  Since the seal part of the pouch is harder than the unsealed part, the first bottom seal part and the second bottom seal part are harder and are more difficult to bend than the unsealed part. Moreover, when a gusset folding part is provided in the bottom part of a pouch, since four films overlap in the position of a gusset folding part, it becomes difficult to bend | fold. For this reason, since the 1st bottom part seal part and the 2nd bottom part seal part are formed in the gusset folding part, it becomes difficult to bend further. On the other hand, according to the present embodiment, the first embossed portion 22 extending from the lower edge 10B toward the spout portion 15 so as to overlap each other at least in each of the first bottom seal portion 19 and the second bottom seal portion 20. And the first embossed portion 22 formed on the first bottom seal portion 19 and the first embossed portion 22 formed on the second bottom seal portion 20 are recessed in the same direction, so the first embossed portion 22 Thus, the pouches 10-1 and 10-2 can be easily folded in half on the front film 11 side. Thereby, since the content can be taken out from the spout part 15 in the above-described procedure, it is possible to provide the pouches 10-1 and 10-2 in which the content hardly remains in the pouches 10-1 and 10-2. Even when the first embossed portion formed on the first bottom seal portion and the first embossed portion formed on the second bottom seal portion protrude in the same direction, the first embossed portion can easily Since it can be folded, it is possible to provide a pouch in which the contents hardly remain in the pouch.

Then, the first end seal part 63 side of the pouch 60-1 is held with one hand, and the pouch 60-1 folded between the index finger and the middle finger of the other hand or between the thumb and the index finger is sandwiched, Slide the other hand toward the opening. Thereby, the contents can be taken out from the opening.

  As described above, since the seal portion of the pouch is harder than the unsealed portion, the first end seal portion is harder and is more difficult to bend than the unsealed portion. In addition, when a metal foil layer such as an aluminum foil layer is used as the intermediate layer of the flexible film, the flexible film becomes hard, so that the first end seal portion is further hardened. On the other hand, according to the present embodiment, at least the first end seal portion 63 includes the second embossed portion 71 including the concave portion 71A extending from the second edge 60B toward the first edge 60A and the third concave portion 72A. Since the embossed portion 72 is formed, the pouch 60-2 can be easily folded in three on the front film 61 side at the positions of the second embossed portion 71 and the third embossed portion 72. Thereby, since the contents can be taken out from the opening in the above-described procedure, it is possible to provide the pouch 60-2 in which the contents hardly remain in the pouch 60-2. When the second embossed part and the third embossed part formed on the first end seal part are both convex parts, the second embossed part formed on the first end seal part is a convex part, and Even when the third embossed portion is a concave portion, and when the second embossed portion formed in the first end seal portion is a concave portion and the third embossed portion is a convex portion, the second embossed portion and the second embossed portion Since the pouch can be easily folded in three at the three embossed portions, it is possible to provide a pouch in which the contents hardly remain in the pouch.
