Description

The present invention relates to a bag with a zipper in which the bag body is closed by a zipper.

Conventionally, a bag with a zipper having a zipper at the opening is known.
In addition, a zippered bag having a tamper-proof function that makes it difficult to open the zipper is also known.
For example, Patent Document 1 describes a bag body having an opening and partitioning a storage space for storing articles, an occlusal portion in which a pair of male and female sack portions can occlude each other, and the occlusal portion, respectively. A bag body with a zipper tape provided with a pair of band-shaped bases to be continuously provided and a zipper tape attached to the inner surface of the bag body, and at least one of the band-shaped bases is on the opening side of the bag body. One edge side corresponding to the bag body and the other edge side corresponding to the storage space side of the bag body are attached to the bag body, and one of the band-shaped bases is the one edge side corresponding to the opening side of the bag body. A bag body with a zipper tape, which is not attached to the bag body and whose other edge side corresponding to the storage space side of the bag body is attached to the bag body, is disclosed.

In such a bag body with a zipper tape, only one of the band-shaped bases is not attached to the bag body on the one edge side corresponding to the opening side of the bag body. Therefore, when the bag body is to be opened, the pair of band-shaped bases are opposite to each other. It is in a state of moving in the direction of shearing the occlusal part in the direction. Therefore, the opening force acts in the direction in which the male side hook portion and the female side hook portion mesh with each other, and it is possible to prevent the bag body from being opened due to the occlusion being disengaged, and tampering can be reliably prevented.

As described above, the bag body with the zipper tape of Patent Document 1 has a falsification prevention function that is difficult to open, so that it is possible to prevent opening due to falsification such as mischief or fraudulent activity (opening based on malicious acts). Furthermore, it is possible to prevent inadvertent opening (unintentional tampering, but accidental opening, etc.). Hereinafter, opening due to falsification and careless opening are collectively referred to as "unplanned opening" or "unplanned opening".
However, such a bag is difficult to open, for example, for the person who purchased it. That is, the bag body with the zipper tape cannot be easily opened when it is desired to be opened normally, not when it is opened unplanned, so improvement is required. Hereinafter, opening that is not unscheduled may be referred to as "regular opening" for convenience.

As used herein, the term "abbreviation" means an acceptable range in the technical field to which the present invention belongs. Abbreviated polygons such as approximately squares, and approximately T-shaped "abbreviations" include, for example, a shape in which the corners are chamfered, a shape in which a part of the side is slightly bulged or recessed, a shape in which the side is slightly curved, etc. Is included. The term "chamfered" means that the corners of the angular portion are removed and the portion is formed into an arc shape or a gentle obtuse angle shape. The "abbreviation" of the substantially circular shape and the substantially elliptical shape includes, for example, a shape in which a part of the circumference is slightly bulged or recessed, a shape in which a part of the circumference is slightly straight or diagonal, and the like.
In the illustrated example, as shown in FIG. 1, the first wall surface sheet portion 21 and the second wall surface sheet portion 22 are both substantially rectangular (or substantially square) in front view and have the same shape and size.

As a bag-making method for the bag body 2 formed of a flexible sheet material, a conventionally known bag-making method such as a packaging bag or a pouch bag can be applied.
For example, in the present embodiment, the bag body 2 is composed of only the first wall surface sheet portion 21 and the second wall surface sheet portion 22. A bag body having an opening 29 above by overlapping the first wall surface sheet portion 21 and the second wall surface sheet portion 22 and sealing the peripheral end portions (lower end portion and both side end portions) excluding the upper end portions thereof. 2 is formed.
In the illustrated example, the first wall surface sheet portion 21 and the second wall surface sheet portion 22 are composed of one sheet material. For example, one sheet material is folded downward and stacked in a double layer (in this case, one of the double sheet materials is the first wall surface sheet portion 21 and the other is the second wall surface sheet portion 22). By adhering both end portions thereof to each other, a bag body 2 having an opening 29 above is formed.
In each front view such as FIG. 1, innumerable dots are added to the portion where the sheet material is adhered in terms of depiction. Further, in each end view such as FIG. 2, the portion where the sheet materials constituting the first wall surface sheet portion 21 and the like are in contact with each other and the portion where the sheet material and the zipper 3 are in contact with each other are portions where they are adhered. Is.

Although not particularly shown, the first wall surface sheet portion 21 and the second wall surface sheet portion 22 may be made of separate sheet materials. In this case, the first wall surface sheet portion 21 and the second wall surface sheet portion 22 made of different sheet materials are overlapped with each other, and the peripheral end portions (lower end portion and both side end portions) excluding the upper end portion are adhered to each other to move upward. A bag body 2 having an opening 29 is formed. Further, the first wall surface sheet portion 21 and the second wall surface sheet portion 22 may be independently composed of two or more sheet materials. In this case, two or more sheet materials are appropriately bonded to form the first wall surface sheet portion 21 and the second wall surface sheet portion 22, respectively, and they are overlapped and the peripheral end portions are bonded as described above. A bag body 2 having an opening 29 is formed above.

The method of adhering the peripheral end portion of the first wall surface sheet portion 21 and the second wall surface sheet portion 22 excluding the upper end portion is not particularly limited, and typical examples thereof include heat welding or adhesion using an adhesive. .. Heat welding is preferable because the sheet material can be easily adhered.
As the sheet material constituting the first wall surface sheet portion 21 and the second wall surface sheet portion 22, conventionally known materials can be used. The sheet material may be either transparent or opaque. The sheet material can be appropriately selected according to the type of articles to be stored, the cost, etc. For example, a synthetic resin sheet having one resin layer or two or more resin layers, paper, synthetic paper, foamed resin sheet, non-woven fabric, etc. Examples thereof include two or more types of laminates to be selected from now on, and laminates of these and a barrier layer.
A desired design is displayed on the bag body 2 including the first wall surface sheet portion 21 and the second wall surface sheet portion 22 by printing or the like as necessary (such a design display is not shown).

The sheet material forming the bag body 2 is preferably composed of a synthetic resin sheet. The resin sheet is required to have basic performance as a bag, such as impact resistance, abrasion resistance, and heat resistance. Further, as described above, since the bag body 2 is usually formed by heat welding of the sheet material, the resin sheet is also required to have heat-sealing properties. As the resin sheet, a multi-layer sheet having a base film layer and a sealant layer that imparts heat-sealing properties is suitable, and when high gas barrier properties and light-shielding properties are required, the base film layer and the sealant layer are used. It is preferable to provide a barrier layer between the two. The base film layer itself may be provided with a barrier property. In this case, the barrier layer is used as the base film layer, and the multi-layer sheet has the barrier layer and the sealant layer. However, in FIGS. 2 and 3 which are cross-sectional views of the zippered bag 1, the first wall surface sheet portion 21 and the second wall surface sheet portion 22 are represented by a one-layer structure (hereinafter, other zippered bags). The same applies to the cross-sectional view of 1).

Here, the constituent materials of the base film layer, the sealant layer, and the gas barrier layer will be illustrated. Lamination of each of these layers can be performed by a conventional laminating method, for example, coextrusion lamination, dry lamination with an adhesive, thermal lamination in which a heat-adhesive layer is sandwiched and heat-bonded.
Examples of the film constituting the base film layer include polyester (polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyvinylidene terephthalate (PBT), polycarbonate (PC), etc.), polyolefin (polyethylene (PE), polypropylene (). PP), etc.), polyamide (nylon-6, nylon-66, etc.), polyacrylonitrile (PAN), polyimide (PI), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polymethylmethacrylate (PMMA), poly A one-layer or two-layer or more stretched or unstretched film composed of ether sulfone (PES) or the like can be exemplified.
The film constituting the sealant layer includes low density polyethylene (LDPE), linear low density polyethylene (LLDPE), ethylene-propylene copolymer (EP), unstretched polypropylene (CPP), and biaxially stretched nylon (ON). , Ethylene-olefin copolymer, ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-vinyl acetate copolymer (EVA), etc. Can be exemplified by a stretched or unstretched film of.
The gas barrier layer may be a metal thin film such as aluminum, a resin sheet such as vinylidene chloride (PVDC) or an ethylene-vinyl alcohol copolymer (EVOH), or an arbitrary synthetic resin sheet (for example, a base film layer). ), An example is a film obtained by depositing (or sputtering) an inorganic oxide such as aluminum, aluminum oxide or silica.
The sheet material may be provided with a printing layer (not shown) for displaying a product description such as a product name, raw materials, precautions for use, and other various designs. For example, the print layer can be formed on the inner surface of the base film layer by a known method such as gravure printing.

The zipper 3 is provided on the inner surface side of the bag body 2 so as to close the opening 29 of the bag body 2. As shown in the drawing, in the bag body 2 in which the opening 29 extends in the width direction, the zipper 3 extends in the width direction in the vicinity of the opening 29 of the bag body 2.
Specifically, the zipper 3 has a first occlusal portion 31 and a second occlusal portion 32 that can be occluded with each other. Examples of the first occlusal portion 31 and the second occlusal portion 32 include those having an occlusal structure of male and female hooks, for example, the occlusal structure disclosed in Patent Document 1 (Japanese Unexamined Patent Publication No. 2015-217980). The first occlusal portion 31 and the second occlusal portion 32 are integrated by occluding each other, and can be separated from each other by releasing the occlusal.
As shown in FIG. 2, the first occlusal portion 31 is composed of, for example, a base portion 311 and a male side hook portion 312 projecting from the base portion 311 toward the second occlusal portion 32 side, and has a width of the bag body 2. It is extended in the direction. The second occlusal portion 32 includes a base portion 321 and a female side hook portion 322 projecting from the base portion 321 toward the first occlusal portion 31 side, and extends in the width direction of the bag body 2. Contrary to the illustrated example, the first occlusal portion 31 may have a female side hook portion and the second occlusal portion 32 may have a male side hook portion.

The first occlusal portion 31 has a pair of extensions toward the upper side (the side opposite to the storage space 28 with respect to the first occlusal portion 31) and the lower side (the storage space 28 side with respect to the first occlusal portion 31). The protrusions 411 and 412 are extended. In the illustrated example, a strip-shaped first upper extending portion 411 extending upward and in the width direction of the bag body 2 is provided at the upper end of the base portion 311 of the first occlusal portion 31, and the first occlusal portion 31 is provided. At the lower end of the base portion 311 of the portion 31, a strip-shaped first lower extending portion 412 extending downward and in the width direction of the bag body 2 is provided.
The second occlusal portion 32 has a pair of extensions toward the upper side (the side opposite to the storage space 28 with respect to the second occlusal portion 32) and the lower side (the storage space 28 side with respect to the second occlusal portion 32). The protrusions 421 and 422 are extended. In the illustrated example, a strip-shaped second upper extending portion 421 extending upward and in the width direction of the bag body 2 is provided at the upper end of the base portion 321 of the second occlusal portion 32, and the second occlusal portion 32 is provided. At the lower end of the base portion 321 of the portion 32, a strip-shaped second lower extending portion 422 extending downward and in the width direction of the bag body 2 is provided.

The first occlusal portion 31 is attached to the inner surface of the first wall surface sheet portion 21 via the first lower extending portion 412 extending downward. The first lower extension portion 412 corresponds to a mounting portion for mounting the first occlusal portion 31 to the first wall surface sheet portion 21. In the first occlusal portion 31 attached only through the first lower extending portion 412, the base portion 311 and the first upper extending portion 411 are separated from the inner surface of the first wall surface sheet portion 21. Therefore, the first occlusal portion 31 and the first upper extending portion 411 do not follow the movement of the upper end portion 21a of the first wall surface sheet portion 21.
The base portion 321 of the second occlusal portion 32 is directly attached to the inner surface of the second wall surface sheet portion 22. Further, the second upper extension portion 421 and the second lower extension portion 422 are also attached to the inner surface of the second wall surface sheet portion 22 together with the base portion 321 of the second occlusal portion 32. The second upper extension portion 421 and the second lower extension portion 422 correspond to attachment portions for attaching the second occlusal portion 32 to the second wall surface sheet portion 22. Therefore, the second occlusal portion 32 and the second upper extending portion 421 follow the movement of the upper end portion 22a of the second wall surface sheet portion 22. The second occlusal portion 32 may be directly attached to the second wall surface sheet portion 22, or the second occlusal portion 32 may be attached to the inner surface of the second wall surface sheet portion 22 only via the second lower extending portion 422. May be attached (not shown).

The second grip portion 52 is provided at a position (lower position) away from the second occlusal portion 32 with reference to the second occlusal portion 32. By providing the second grip portion 52 at such a lower position, the second action region 62 is secured between the base end portion 521 and the second occlusal portion 32 of the second grip portion 52. The second working area 62 is a part of the in-plane area of the second wall surface sheet portion 22. The second grip portion 52 is provided on the second wall surface sheet portion 22 by connecting the base end portion 511 to the outer surface of the second wall surface sheet portion 22. In the present embodiment, the second grip portion 52 is provided on the outer surface of the second wall surface sheet portion 22 with its base end portion 521 upward and the end portion 522 on the side opposite to the base end portion 521 downward. There is.
Hereinafter, the end portion on the opposite side to the base end portion is referred to as "opposite end portion".

The length H1 from the base end portion 511 to the first occlusal portion 31 of the first grip portion 51 and the length H2 from the base end portion 521 to the second occlusal portion 32 of the second grip portion 52 are not particularly limited. If it is too small, it is substantially the same as when the first grip portion 51 and the second grip portion 52 are provided at positions corresponding to the first occlusal portion 31 and the second occlusal portion 32. The 51 and the second grip portion 52 become difficult to handle. From this point of view, the length H1 from the base end portion 511 of the first grip portion 51 to the first occlusal portion 31 (this length H1 corresponds to the vertical length of the first working region 61), and the first 2 The length H2 from the base end portion 521 of the grip portion 52 to the second occlusal portion 32 (this length H2 is the base end portion 521 of the second grip portion 52 corresponding to the vertical length of the second action region 62). The distance between the second occlusal portion 32 and the second occlusal portion 32 in the vertical direction) is, for example, 5 mm to 40 mm, preferably 10 mm to 30 mm, respectively.

The first grip portion 51 and the second grip portion 52 may be provided at the same height position in the vertical direction of the bag body 2, or one of them may be displaced upward. In the illustrated example, the first grip portion 51 and the second grip portion 52 are provided at the same height position (positions facing each other across the bag body 2) in the vertical direction of the bag body 2.

The first grip portion 51 and the second grip portion 52 are formed of, for example, a flexible sheet material. The sheet materials constituting the first grip portion 51 and the second grip portion 52 are not particularly limited, and can be appropriately selected and used from the sheet materials exemplified as the sheet materials constituting the first wall surface sheet portion 21. .. The sheet material constituting the first grip portion 51 and the sheet material constituting the second grip portion 52 may be the same sheet material or may be different. The sheet materials constituting the first grip portion 51 and the second grip portion 52 and the sheet materials constituting the first wall surface sheet portion 21 and the second wall surface sheet portion 22 may be the same sheet material or may be different. You may be. For example, when the first grip portion 51 and the first wall surface sheet portion 21 are made of separate sheet materials (both sheet materials themselves may be the same material or different materials), the first grip portion 51 is the first wall surface. It is adhered to the outer surface of the sheet portion 21 by heat welding or the like. Further, the first grip portion 51 is formed by using a partially adhesive label (also referred to as a tack label) in which the adhesive is partially exposed, and the adhesive label is attached to the first wall surface sheet portion 21 via the adhesive. The first grip portion 51 may be formed on the first wall surface sheet portion 21 by adhering. The same applies when the second grip portion 52 and the second wall surface sheet portion 22 are made of separate sheet materials.
If necessary, the desired design is displayed on the first grip portion 51 and the second grip portion 52 by printing or the like.

In the illustrated example, the base end portion 511 and both side end portions of the first grip portion 51 made of a sheet material are connected in the plane of the first wall surface sheet portion 21, and the base end portion 511 and the base end portion 511 of the first grip portion 51 and the first grip portion 51 are connected to each other. Except for both end portions, it is not connected to the outer surface of the first wall surface sheet portion 21 and is separated from the first wall surface sheet portion 21. Therefore, the first grip portion 51 and the first wall surface sheet portion 21 cooperate to form a space 519, and the space 519 is formed between the opposite end portion 512 of the first grip portion 51 and the first wall surface sheet portion 21. A first insertion portion 518 continuous with the space 519 is formed. The first insertion portion 518 and the space 519 are sized so that at least one finger can be inserted.
Further, the base end portion 521 and both side end portions of the second grip portion 52 made of the sheet material are connected in the plane of the second wall surface sheet portion 22, and the base end portion 521 and both side ends of the second grip portion 52 are connected. Other than the portion, it is not connected to the outer surface of the second wall surface sheet portion 22, and is separated from the second wall surface sheet portion 22. Therefore, the second grip portion 52 and the second wall surface sheet portion 22 cooperate to form a space 529, and the space 529 is formed between the opposite end portion 522 of the second grip portion 52 and the second wall surface sheet portion 22. A second insertion portion 528 that is continuous with the space 529 is formed. The second insertion portion 528 and the space 529 are sized so that at least one finger can be inserted.

The vertical length L1 of the first grip portion 51 and the vertical length L2 of the second grip portion 52 are not particularly limited, but if they are too small, it is difficult to pinch the first grip portion 51 and the second grip portion 52. If it is too large, it becomes difficult to handle the first grip portion 51 and the second grip portion 52. From this point of view, the vertical length L1 of the first grip portion 51 and the vertical length L2 of the second grip portion 52 are independently, for example, 5 mm to 100 mm, preferably 10 mm to 50 mm. Is.

In the illustrated example, the first grip portion 51, the second grip portion 52, the first wall surface sheet portion 21, and the second wall surface sheet portion 22 are composed of one sheet material. For example, one sheet material is folded downward and double-layered, and one and the other of the double sheet materials are folded while being pulled out so as to form folds, and then both end portions are bonded to each other.
