Description

  The present invention relates to a standing pouch that has excellent shape retention and independence, and is easy to hold when pouring contents.

  Liquid products such as detergents and shampoos are usually marketed in containers such as bottles and bottles, but empty containers after the contents have been consumed have been discarded. However, in recent years, from the viewpoints of resource saving, disposal processing, and cost reduction, the contents for refilling are often housed in a standing pouch (also called a self-supporting bag) and sold separately.

  A standing pouch is a simple container using a soft packaging material. This soft packaging material can be used as a refilling container used to replenish a container such as a used bottle with the same contents, and can also be used as an alternative to a shape retaining container such as a plastic bottle, a glass bottle, or a metal can.

  Since the standing pouch is made of a soft packaging material, the standing pouch is flexible, and has excellent self-supporting properties when the contents are filled and unopened. Furthermore, a heat seal is provided in the lower gusset part of the standing pouch. Furthermore, in order to make the opening and shape retention of the spout part more stable, a plastic molding is used on the upper part of the standing pouch. Some have a spout attached.

  Patent Document 1 discloses a technique related to a standing pouch with improved independence. Specifically, in order to improve the independence, shape retention, and stability of the standing pouch, the body of the bag is injection molded. This is a technique related to a standing pouch manufactured by joining a columnar reinforcing member to a part of the peripheral edge at the same time as forming.

  Patent Document 2 discloses a technique related to a standing pouch with improved ease of holding. Specifically, as a seal pattern having a shape that gives self-supporting property to heat-seal the lower gusset portion, the technology relates to a self-supporting bag having a seal pattern in which the inner side is recessed from both sides toward the central portion. By providing a holding hole in the heat seal part at the top of the bag, it becomes easier to hold and the contents can be easily transferred.

  However, the conventional techniques as described in the above [0004] and the disclosed techniques described in Patent Documents 1 and 2 have the following problems.

  Standing pouches use soft packaging materials, so if the remaining amount of the contents is low, the self-supporting and shape retention properties will deteriorate, and the bag will be folded (middle folded) in the middle of the bag, the bag mouth will face down, There is a possibility of leakage. In particular, when a spout is provided in the upper part of the bag, the stability is deteriorated due to the weight of the spout, and the bag is easily folded or falls. Also, if the bag breaks when the contents are poured out, the contents may not be poured sufficiently or may spill around.

  Also, when transferring or pouring the contents of the standing pouch to another container, the body of the soft packaging material bag is soft and cannot hold the body strongly, so the upper and lower parts of the bag must be supported by hand from below. It is common to pour out. However, it is difficult to hold because there is no part to be a handle, and in particular, when the capacity of the bag is increased to 1 L to 1.5 L, it is difficult to hold by hand, and the transfer operation is very difficult to perform.

  In the technique disclosed in Patent Document 1, the reinforcing member is attached to the peripheral portion including the upper portion of the bag, so that the self-supporting property, the shape retaining property, and the stability are improved, but it does not have a handle. Therefore, the ease of holding the bag is hardly improved.

  In the technology disclosed in Patent Document 2, the bag filled with the contents has a bottom portion that widens back and forth due to the lower gusset portion and its seal pattern, and a leg portion formed by a heat seal portion is formed on the outer periphery of the bottom surface. Therefore, although excellent self-supporting property is imparted, a space for storage is required because the bottom portion is greatly expanded.

  The present invention has been made to solve the above-described problems of the prior art, and is excellent in self-supporting property, shape retention and stability, easy to hold when pouring contents, etc., and has a small storage space. A standing pouch that can also be provided.

  As shown in FIG. 1, the standing pouch according to the present invention includes a bag 1 for storing contents, and a pouring part 2 attached to an upper portion of the bag 1. The bag 1 has a body part 3 and a gusset part 4, and the body part 3 is formed with side seal parts 5 in which the left and right end edges of the wall film 7 on the front and rear surfaces are heat sealed. ing. In FIGS. 1, 2, 4, and 5, the seal portion including the side seal portion 5 is hatched. The gusset part 4 is formed by folding back and inserting the bottom film 13 between the lower parts of the front and rear wall films 7 and sealing the peripheral part by heat sealing. Further, a constricted portion 8 constricted inward is formed at one end edge portion of the body portion 3, and a handle 10 made of a rigid member is attached so as to substantially follow the side seal portion 5. . As can be seen from FIGS. 1 and 2, the standing pouch of the present invention is configured in the same form on the front surface side and the back surface side.

  The film used for the wall surface film 7 and the bottom film 13 constituting the standing pouch is a soft packaging material having a basic layer structure of “base layer / sealant layer”, and the sealant layer is the inner surface of the bag. It becomes the side layer.

As a film constituting the base material layer, biaxially stretched polypropylene film (OPP), biaxially stretched nylon film (ONy), biaxially stretched polyester film (PET), unstretched polypropylene film, unstretched nylon film, cellulose film Synthetic paper, metal foil (aluminum foil, etc.) can be exemplified. The base material layer may be composed of two or more layers. The base material layer is a gas barrier resin layer (ethylene-vinyl alcohol copolymer layer, acrylonitrile polymer layer having a high acrylonitrile content, polyvinylidene chloride resin layer, etc.), adhesive resin layer, anchor coating layer, vapor deposition layer (Metal vapor-deposited layer or ceramic vapor-deposited layer), printing layer (patterned or solid, formed on the inner or outer surface of the base material layer), topcoat layer (acrylic resin, epoxy resin, phenolic resin, urea-based) Resin, melamine resin, maleic acid resin, polyurethane resin, cellulose resin, and the like). The thickness of the base material layer is arbitrary as long as a predetermined strength can be obtained, but is often about 12 to 120 μm, for example.

  Materials for the sealant layer include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE), ethylene-vinyl acetate copolymer (EVA), ethylene- Various heat-sealable properties, including polyethylene resins such as saturated carboxylic acid ester copolymers, ethylene-unsaturated carboxylic acid copolymers, ionomers, ethylene-propylene copolymers, and polypropylene resins called CPP Resin layer. The sealant layer may be composed of two or more layers. The thickness of the sealant layer is not limited, but is often about 5 to 200 μm, particularly about 15 to 170 μm.

  The lamination between each layer is performed by a method such as a dry laminating method, a wet laminating method, a casting method, a sand laminating method, a coextrusion method, an extrusion coating method, and a printing method, except in the case of forming a vapor deposition layer.

  The left and right edge portions of the wall film 7 heat-sealed by the side seal portion 5 have a constricted portion 8 as shown in FIG. The constricted portion 8 is formed by narrowing the width of the bag with a curve, and the shape of the curved portion is preferably an arc shape, an elliptical arc shape, or the like. As shown in FIG. 2, the constricted portion 8 can be formed on both side edge portions of the body portion 3, but it is sufficient that it is formed on at least one side edge portion to which the handle 10 is attached.

  The bottom film 13 is made of a flexible packaging material composed of the same base material layer and sealant layer as the wall film 7. As shown in FIG. 3, the two bottom films 13 are inserted between the lower portions of the wall film 7 so that the base material layers face each other so as to be folded at the bottom film folding portion 14, and the peripheral portion is heated. The gusset portion 4 is formed by sealing with a seal.

  The pouring part 2 is made of a synthetic resin molded body, and is joined to the upper seal part 9 by heat sealing as shown in FIGS. Therefore, it is preferable that the material of the extraction | pouring part 2 is a material which has the layer of the thermoplastic resin which can be heat-sealed with the wall surface film 7 at least on the surface. The dispensing part 2 is sealed with a cap 15. The cap 15 is detachable from the pouring portion 2 so that the cap 15 can be repeatedly sealed after a part of the contents is taken out.

  As shown in FIG. 1, the handle 10 is attached so that the edge portions on both sides of the wall film 7 substantially follow one edge portion of the body portion 3 heat-sealed by the side seal portion 5. ing. The handle 10 is joined and attached to the side seal portion 5 at the joint portion 12. There are a plurality of joints 12 from the lower part to the upper part of the standing pouch, but they are not in the constricted part 8. That is, the handle 10 is joined to the side seal portion 5 only at the upper and lower portions of the constricted portion 8, and is not joined to the side seal portion 5 at the constricted portion 8.

  The material of the handle 10 is made of a rigid material, and the material is not limited as long as the material can impart shape retaining property and self-supporting property to the standing pouch, and may be a metal, but a synthetic resin is more preferable. Examples of synthetic resins include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyvinyl acetate (PVAc), polytetrafluoroethylene, ABS resin (acrylonitrile butadiene styrene resin), AS Resin (acrylonitrile styrene resin), acrylic resin, etc. are mentioned.

  By attaching the handle 10, which is a rigid member, so as to be substantially along the side seal portion 5, the shape retaining property and the self-supporting property of the standing pouch are improved, and the bag is folded or falls due to the weight of the pouring portion. It can be stored in a stable and stable state. In addition, by attaching the handle 10, it becomes possible to improve the independence without expanding the bottom portion, so that it can be stored without taking up space.

  The handle 10 has a bent portion 11 that is recessed so as to substantially follow the constricted portion 8 of the side seal portion 5, and the handle 10 is joined only at the upper and lower portions of the constricted portion 8 of the side seal portion 5. Has been. The shape of the bent portion 11 of the handle 10 is not limited. However, since it is possible to hold the finger along the bent portion 11, it is particularly preferable to have a curved shape such as an arc shape or an elliptical arc shape. Thus, by having the bending part 11 in the handle 10, it becomes easy to have a standing pouch, and the content can be poured easily or transferred to another container.

  As shown in FIG. 1, the edge portion of the bag 1 which is heat-sealed has a width of the side seal portion 5 where the handle 10 is joined, which is wider than the other side seal portions. 10 is wider than the side seal portion 5, the side seal portion 5 is firmly held by the handle 10 to improve the self-supporting property of the bag 1, and the bag is less likely to bend, It becomes easier to hold a pouch.

  As shown in FIG. 1, the handle 10 is attached so that the inner end 16 of the bent portion 11 is outside the inner end 16 of the side seal portion 5 of the constricted portion 8. When the finger is placed along the bent portion 11, it becomes difficult for the finger to come into contact with the body portion 3 containing the contents, and it becomes easier to hold a standing pouch when carrying or pouring.

  As shown in FIGS. 1 and 2, the handle 10 is composed of two plate-like members, and is joined so as to sandwich the side seal portion 5 from both the front and back surfaces. Thereby, while the rigidity of the handle 10 can be improved, the side part seal part 5 can be shape-retained from both front and back. Therefore, it is possible to further improve the independence and ease of holding of the standing pouch. Although the thickness of each plate-shaped member is not specifically limited, For example, it shall be 1-2 mm. The width of the handle 10 is not particularly limited, but is preferably 10 to 20 mm.
