Description

  The present invention relates to a structure of a packaging bag containing a plurality of individually packaged food contents, and more particularly, to unpack individual contents to use the individually packaged food contents. The present invention relates to a packaging bag having a space for storing an individual packaging material that has been unwound when an object is taken out.

  Conventionally, contents such as strawberries, chocolates, pies, and cookies are individually or individually packaged, and the individually packaged plurality are stored in a larger packaging bag (exterior bag) and sold. When these contents are eaten indoors at home, etc., the individual packaging material after unpacking the contents and taking out the contents is thrown into the trash can etc. installed in the room, so it is scattered inside the room. No, it doesn't pollute the room.

  However, when eating the above-mentioned contents outdoors, if there is no trash can in the vicinity, it may be difficult to discard the individual packaging material after unpacking the contents and taking out the contents. In this case, it is unavoidable to temporarily put it in a bag or pocket, bring it to a place where there is a trash box, etc., and then discard it in the trash box. If it is temporarily put in a pocket or the like, the smell or oil may adhere to the bag or pocket, and there is a problem that some people have a little resistance to putting it directly into the bag or pocket.

  Therefore, if the above problem is a concern, the individual packaging material after the contents are taken out may be returned to the outer bag again, and the outer bag may also be used as a trash can. Since the packaging and the individual packaging material after the contents are taken out are mixed in the outer bag, it is a little troublesome to find and take out the individual packaging containing the contents from the outer bag.

  In an extreme case, there is also a problem that the individual packaging material after the contents are taken out is thrown away on the road as a trash can and scattered on the road and the road is soiled.

In addition, there exists what is disclosed in the paper box as what solves this kind of problem (for example, refer patent document 1). Patent Document 1 is provided with a reaction lid that opens only when an object is pushed into one end of a rectangular tube-shaped paper box and is closed in other cases, and a slidable separation plate is provided inside to accommodate trash. The confectionery paper box is disclosed, but since the applicant has not recognized prior art documents that disclose contents directly related to the characteristics of the packaging bag of the present invention, However, prior art document information is not described.

The bottom material S2 which is folded into a substantially V shape so that the conductive resin layer is exposed and provided with the semicircular cutouts 4 at both ends is connected to one end edge of the body S1 and the one end edge. Two end edges are inserted so that the end edges coincide with each other, and the surface material S3 is connected to the one end edge and the one end edge of the body S1. Are arranged so as to coincide with each other, and the surface material S3 is sealed on the surface of the one body S1, which is sealed by the left and right edge thermal bonding portions 2 and 2 'and the upper and lower edge thermal bonding portions 3 and 3'. It is a standing type packaging bag that is bonded and fixed so as to form a bag shape having an opening at the upper edge thermal bonding portion 3 ′ side. The lower edge thermal bonding part 3 is a well-known standing pouch except that the inner edge is thermally bonded so as to have a boat shape and the surface material S3 is provided. In FIG. 1, the symbol G indicates a gusset portion.

  Although not illustrated, the packaging bag 1 configured in this way is provided on the upper edge thermal bonding part 3 ′ side of the packaging bag 1, for example, I-shaped, V-shaped, U-shaped, turtle-shaped, etc. The individual packaging material which is opened by using an opening means such as a notch or a notch and is taken out and stored in the inside is unpacked and the contents are taken out by unpacking the individual packaging material. The space formed by the body material S1 and the surface material S3 can be used as a trash can through the opening on the upper end edge thermal bonding portion 3 'side of the surface material S3 provided on the surface, and can be stored in this space. In addition, it can be processed smartly, and after the contents have been used up, the individual packaging material as garbage stored in the space can be disposed of together with the packaging bag 1 very efficiently at a time. In the embodiment, the surface material S3 is provided on one surface of the packaging bag 1. However, depending on the number of individually packaged items stored inside, the individual packaging material as garbage is stored. The surface material S3 may be provided also on the other surface of the packaging bag 1 for the purpose of securing more space to be used.

  Next, the body material S1, the bottom material S2, and the surface material S3 constituting the packaging bag of the present invention will be described. First, the body material S1 and the bottom material S2 will be described. Each of them has a configuration including at least a base material layer and a heat-adhesive resin layer, and the body material S1 and the bottom material S2 have the same specifications. The body S1 may be composed of different specifications, and the front and back of the body S1 may be composed of different specifications.

  The heat-adhesive resin layer constituting the body material S1 and the bottom material S2 may be any material that can be melted by heat and fused to each other. For example, low-density polyethylene, medium-density polyethylene, Density polyethylene, linear (linear) low density polyethylene, polypropylene, ethylene-vinyl acetate copolymer, ionomer resin, ethylene-acrylic acid copolymer, ethylene-methyl acrylate copolymer, ethylene-methacrylic acid copolymer A resin composed of one or more resins such as ethylene-propylene copolymer or a sheet obtained by forming a film of these resins can be used, and the thickness is suitably from 30 to 200 μm.

  Moreover, since it becomes a basic material which comprises a packaging bag as a base material layer, the synthetic resin which has the property excellent in mechanical, physical, chemical, etc. can be used, for example, polyester type, polyamide type Polypropylene, polycarbonate, and polyacetal resins can be used. Further, since the synthetic resin film used as the outer layer is generally printed on the inner layer side of the synthetic resin film, the synthetic resin film used as the outer layer is printable. Therefore, a stretched film stretched in the biaxial direction is preferable. The thickness of the film may be a thickness that can be kept to the minimum necessary with respect to strength, rigidity, etc. as a basic material, and about 12 to 25 μm is appropriate considering the cost. In addition, the synthetic resin film was formed with a film coated with polyvinylidene chloride as needed, or an inorganic vapor deposition layer such as aluminum, silicon oxide, aluminum oxide, indium oxide, tin oxide, or zirconium oxide. The film may have a barrier property. Moreover, synthetic paper, non-woven fabric, paper, cellophane, etc. can be used as needed. Further, in the present invention, a surface material S3 is provided on at least one surface of the body S1 constituting the packaging bag 1 so as to form a bag shape having an upper edge thermal bonding portion 3 'opened, and functions as a trash can.

For example, a heat-sealable biaxially stretched polypropylene film [Tosero Co., Ltd.], which has a layer that can be thermally bonded to the exposed surface of the synthetic resin film constituting the base material layer of the body S1. Product: HC-OP (trade name) Toyobo Co., Ltd .: P3162 (trade name)], heat-sealable biaxially stretched polyethylene terephthalate film [Toyobo Co., Ltd .: E7700 (trade name), Teijin Deyupon Co., Ltd .: Mylar 850 (trade name)], etc. Of the type.

  Moreover, in the trunk | drum S1 and bottom material S2 of this invention, you may provide an intermediate | middle layer between the said thermoadhesive resin layer and the said base material layer, and the said intermediate | middle layer is usually the said thermoadhesive resin layer and the said It is provided when the function as a packaging bag cannot be sufficiently achieved with the base material layer alone. The functions include gas barrier properties, mechanical toughness, flex resistance, puncture resistance, impact resistance, cold resistance, heat resistance, chemical resistance, etc., and are required as packaging bags by providing an intermediate layer. To achieve these final functions. Examples of the base material used as the intermediate layer include metal foils such as aluminum, iron, copper, and tin, polyesters such as polyethylene terephthalate and polycarbonate, and polyolefins such as polyamide, polyethylene, polypropylene, and an ethylene-propylene copolymer. Films of polyvinyl chloride, polyvinyl alcohol, ethylene-vinyl alcohol, etc., or films coated with polyvinylidene chloride on these films, or inorganic materials such as aluminum, silicon oxide, aluminum oxide, indium oxide, tin oxide, zirconium oxide, etc., are deposited. Film, polyvinylidene chloride film, paper, cellophane, synthetic paper or the like can be used. One or more of these substrates can be used in combination. It should be noted that the thickness of the base material only needs to satisfy the function required as a packaging bag, and can be appropriately selected as necessary.

  In addition, for the purpose of imparting easy-openability to the packaging bag 1, a uniaxially stretched film stretched in the tear-opening direction on the base material layer and / or the intermediate layer may be used.

  Next, the surface material S3 will be described. As the surface material S3, in the case of bonding and fixing to the body material S1 using an adhesive such as a hot melt adhesive, the polyester material constituting the base material layer described in the body material S1 and the bottom material S2, A film made of a polyamide-based, polypropylene-based, polycarbonate-based, or polyacetal-based resin may be used. When the surface material S3 is provided at the same time when the bag is made by the bag making machine, It is preferable that the heat-bondable layer provided on the exposed surface of S1 and the surface material S3 are provided by heat bonding, and the structure of the surface material S3 is the base material layer described in the body material S1 and the bottom material S2. And the heat-adhesive resin layer are suitable. However, considering that the surface material S3 forms a space for a trash can, the cost may be low, and the heat sealability described above Axial stretched polypropylene film [manufactured by Tosero Co., Ltd .: HC-OP (trade name), Toyobo Co., Ltd .: P3162 (trade name)], heat sealable biaxially stretched polyethylene terephthalate film [manufactured by Toyobo Co., Ltd .: E7700 ( (Trade name), manufactured by Teijin Deyupon Co., Ltd .: Mylar 850 (trade name)] and the like are best.
