The front sheet of the storage bag according to the present invention may be transparent. Since the transparent material is generally not made of paper, the storage bag can be realized from the front sheet made of non-paper and the back sheet main body made of paper. Further, since the object to be accommodated in the accommodating portion is transparent through the front sheet, the object to be accommodated can be visually recognized from the outside.

In the storage bag according to the present invention, if the sticking portion is arranged so as to be adjacent to the opening of the housing portion, the opening can be closed by the sticking portion.

The storage bag manufacturing method according to the present invention includes a procedure for forming a release layer by applying a release agent to one end or both ends of the surface of the back sheet main body and drying it, and an adhesive on the release layer. And the procedure of forming an adhesive layer at the end of the back sheet body excluding the release layer, and the procedure of adhering the front sheet to the back sheet body via the adhesive layer and the adhesive part. It goes through a procedure and a procedure for cutting between the adhesive layer and the adhesive portion in the back sheet main body. Since the back sheet main body is cut between the adhesive layer and the adhesive portion, the side bonded to the adhesive layer becomes a release paper, so that the back sheet main body is originally a single sheet before being cut. Therefore, it is not necessary to prepare the paper pattern separately from the back sheet body. Therefore, the storage bag is realized by the front sheet and the back sheet main body in a two-layer structure, and the storage bag can be manufactured at a lower material cost as compared with the three-layer structure.

In the storage bag manufacturing method according to the present invention, in the procedure for forming the adhesive portion, an adhesive portion is formed between the ends of the back sheet main body excluding the release layer, and the back sheet main body is formed via the adhesive layer and the adhesive portion. By laminating the front sheets, a single or multiple accommodating areas can be formed. Therefore, a storage bag that can store the objects to be stored separately for each of a plurality of storage areas can be realized with a two-layer structure, and the storage bag can be manufactured at a lower material cost as compared with the three-layer structure. it can. Further, in addition to the end portion of the back sheet main body excluding the release layer, the adhesive is applied between the end portions at the same time, so that the storage bag can be manufactured at high speed.

In the storage bag manufacturing method according to the present invention, an adhesive portion can be formed by applying an adhesive. In this case, since the pressure-sensitive adhesive forming the pressure-sensitive adhesive layer can form the pressure-sensitive adhesive layer and the adhesive portion, the material can be simplified as compared with the case where the adhesive is used.

In the storage bag manufacturing method according to the present invention, the procedure for forming the adhesive layer and the procedure for forming the adhesive portion may be performed at the same time. In this case, since the adhesive layer and the adhesive portion are formed at the same time, the process can be simplified.

In the storage bag manufacturing method according to the present invention, a mold release agent that dries by irradiating with ultraviolet rays can be used. In this case, since the release agent is dried with ultraviolet rays before being excessively impregnated, inexpensive paper having no barrier layer can be used. In addition, since the release agent is instantly dried by ultraviolet rays, there is no need to dry the release agent in a hot air drying oven or to wind it into a roll and age it for a long time. Can be manufactured.

The storage bag manufacturing method according to the present invention does not have to go through the procedure of drying the adhesive layer. That is, by using the back sheet main body having no barrier layer, it is not necessary to go through the procedure of drying the adhesive containing the solvent, which has been conventionally required, before the storage bag is formed. Generally, paper having a barrier layer has a reduced moisture permeability due to the barrier layer, but when the back sheet body does not have a barrier layer, the moisture permeability is maintained. The adhesive applied to the back sheet body is naturally dried through the back sheet body even when the front sheet is attached before drying. Therefore, it is possible to efficiently manufacture the storage bag at once with one device without going through the procedure of drying the adhesive.

Hereinafter, the storage bag according to the first embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the usage state of the storage bag 10 according to the first embodiment. FIG. 2 shows an outline of the storage bag 10.

As shown in FIG. 1, the storage bag 10 contains a delivery statement, an invoice, a guide, a product sample, etc. as a storage target 1, and is a box 2 as an attachment target, which is an exterior of a package. It is attached to the outer surface. Therefore, the storage bag 10 has a storage portion 11 in which the storage target 1 is housed, and a sticking portion 12 to be attached to the box 2. The position where the storage bag 10 is attached to the box 2 is arbitrary, and may be the upper surface as well as the side surface of the box 2.

As shown in FIG. 2, the storage bag 10 has a rectangular shape and has a two-layer structure in which two sheets are bonded together. The storage bag 10 has a rectangular front sheet 13 and a rectangular back sheet main body 24, and the back sheet main body 24 is divided into a back sheet 25 and a release sheet 26. That is, since the front sheet 13 and the back sheet 25 are formed in a bag shape, the accommodating portion 11 having the accommodating area 21 is formed between them, and the sticking portion 12 is formed by the front sheet 13 and the release sheet 26. ing. The sticking portion 12 is connected to both ends of the accommodating portion 11. The shape of the storage bag 10 is arbitrary and may be square or the like, but considering that the storage target 1 is an envelope or the like, it is preferable that the storage bag 10 is a rectangle in which the envelope is accommodated.

The front sheet 13 has an accommodating portion constituent surface portion 14 which is the center of the front sheet 13 and occupies most of the area, and a sticking portion constituent surface portion 15 which is connected to both sides of the accommodating portion constituent surface portion 14. The area ratio between the accommodating portion constituent surface portion 14 and the pasting portion constituent surface portion 15 is arbitrary, but in view of the function as the accommodating portion 11 for accommodating the object to be accommodated 1, the accommodating portion constituent surface portion 14 may be wider. preferable. Of the four ends of the back surface of the accommodating portion constituent surface portion 14, the first end portion 16 of the long side, the second end portion 17 of the long side facing the first end portion 16 in the plane direction, and one short end portion The third end portion 18 of the side has an adhesive layer 19 as an adhesive portion along each of the end portions 16, 17, 18. The adhesive layers 19 at the ends 16, 17, and 18 are connected to each other, and the back sheet 25 is adhered. On the other hand, the end portion of the accommodating portion constituent surface portion 14, which is the other short side of the back surface, does not have the adhesive layer 19, and the opening 20 is formed between the accommodating portion constituent surface portion 14 and the back sheet 25. Therefore, the accommodating area 21 is formed inside the area surrounded by the adhesive layer 19, and the opening 20 leads to the accommodating area 21.

The back surface of the sticking portion constituent surface portion 15 has an adhesive layer 22 and a picking allowance 23. The adhesive layer 22 is slightly narrower than the sticking portion constituent surface portion 15, and a pinching allowance 23 is formed at the end of the sticking portion constituent surface portion 15 which is a portion that does not have the adhesive layer 22. The picking allowance 23 may be formed only on the side close to the accommodating portion 11 or the end side opposite to the accommodating portion 11. A release sheet 26 is attached to the adhesive layer 22. The release sheet 26 has a release layer 27 impregnated on the surface. The release layer 27 is slightly wider than the adhesive layer 22 and covers the adhesive layer 22.

The back sheet 25 has the same shape as the accommodating portion constituent surface portion 14 of the front sheet 13, and is adhered to the accommodating portion constituent surface portion 14 via the adhesive layer 19. The release sheet 26 is adjacent to both ends of the back sheet 25 in the plane direction, has the same shape as the sticking portion constituent surface portion 15 of the front sheet 13, and is stuck to the sticking portion constituent surface portion 15 via the adhesive layer 22. There is. Therefore, the sticking portion 12 composed of the sticking portion constituent surface portion 15 and the release sheet 26 is adjacent to the opening 20 of the accommodating portion 11.

The front sheet 13 is a transparent film made of plastic, for example, a polyethylene film, a polypropylene film, or the like. The transparency is arbitrary, but it is preferable that the contained object 1 can be seen through. The back sheet main body 24 is, for example, uncoated paper such as high-quality paper, in other words, a sealing paper having a barrier layer for preventing excessive impregnation of a release agent such as silicone, or glassine paper. Not like that.

As described above, the storage bag 10 is configured. Next, how to use the storage bag 10 will be described. FIG. 3 shows an outline of the usage state of the storage bag 10.

As shown in FIG. 3, the object to be accommodated 1 is accommodated in the accommodating portion 11 through the opening 20. When the release sheet 26 is peeled off from the front sheet 13, the adhesive layer 22 is exposed on the front sheet 13. When the storage bag 10 is applied to the box 2 in this state, the storage bag 10 is attached to the box 2 via the adhesive layer 22. Since the sticking portion 12 is adjacent to the opening 20, the adhesive layer 22 is stuck to the box 2 to close the opening 20.

The storage bag 10 is not attached to the outer surface of the box 2 or the like, and is also used as an envelope, for example, by folding the attaching portion 12 to the back side and attaching it to the back surface of the back sheet 25. In this case, the object to be attached is the back surface of the back sheet 25. Further, if the front sheet 13 is a non-transparent paper, the accommodation target 1 can be concealed.

Next, a storage bag manufacturing method will be described. The storage bag manufacturing method is realized by a single storage bag manufacturing device (not shown), and the storage bag 10 is manufactured by so-called one-pass manufacturing.

The storage bag manufacturing apparatus is separated from a front sheet roll, which is a roll-shaped front sheet 13, a paper feeding unit that feeds a sheet from the back sheet roll, which is a roll-shaped back sheet main body 24, and a part of the back sheet main body 24. The coating portion forming the mold layer 27, the coating portion forming the adhesive layer 22 and the adhesive layer 19, the laminating portion for bonding the front sheet 13 and the back sheet main body 24, and the back sheet main body 24 are peeled off from the back sheet 25. It has a cut portion that cuts into a sheet 26 and cuts a storage bag 10 into a predetermined size. The storage bag manufacturing apparatus may have a printed portion for printing on the front sheet 13 and / or the back sheet main body 24.

Sheets are fed from the front sheet roll and the back sheet roll set in the paper feed section. In the coated portion, the release agent is applied only to both ends of the surface of the back sheet main body 24 and dried to form the release layer 27. The release agent is, for example, solvent-free silicone. Here, since the back sheet main body 24 does not have a barrier layer, it is difficult to suppress the impregnation of the release agent, but by irradiating with ultraviolet rays, before the release agent is excessively impregnated. It dries instantly.

In the coating portion, an adhesive is applied on the release layer 27 to form the adhesive layer 22, and at the same time, between the release layers 27 at both ends, the release layer 27 on the surface of the back sheet main body 24 and the release layer 27 are accommodated. An adhesive is applied to the end portions 16, 17, 18 (in other words, the portion of the front sheet 13 that faces the end portion of the accommodating portion constituent surface portion 14) excluding the region 21 to form the adhesive layer 19. The pressure-sensitive adhesive is, for example, an aqueous glue. The front sheet 13 is attached to the back sheet main body 24 via the adhesive layer 22 and the adhesive layer 19 in the laminating portion without going through the procedure of drying the adhesive layer 22 and the adhesive layer 19. The portion surrounded by the ends 16, 17, and 18 forms a single accommodation area 21. Here, since the back sheet main body 24 does not have a barrier layer, the moisture permeability is maintained, and the adhesive layer 22 is naturally dried even after the front sheet 13 is attached. That is, in the storage bag manufacturing method, the procedure of forcibly drying the adhesive layer 22 is not performed before the storage bag 10 is formed.

In the cut portion, the adhesive layer 22 and the adhesive layer 19 are cut at the back sheet main body 24, and the back sheet main body 24 is divided into a back sheet 25 and a release sheet 26. Finally, it is cut into a predetermined size suitable for the product, and the storage bag 10 is completed.

As described above, the storage bag manufacturing method is executed. Next, the effect of this embodiment will be described.

As described above, the storage bag 10 has a two-layer structure in which two sheets of a rectangular front sheet 13 and a rectangular back sheet main body 24 are bonded to each other, and the back sheet main body 24 has a back sheet 25 and a release sheet 26. It is divided into and. The accommodating portion constituent surface portion 14 of the front sheet 13 and the back sheet 25 are adhered to each other via the adhesive layer 19 to form a bag shape, whereby the accommodating portion 11 is formed, and the accommodating portion constituent surface portion 15 of the front sheet 13 is attached. And the release sheet 26 form a sticking portion 12. Therefore, the material cost is low as compared with the three-layer structure.

Further, in the back sheet main body 24, since the adhesive layer 22 and the adhesive layer 19 are cut off, the side bonded to the adhesive layer 22 becomes a paper pattern, so that the back sheet main body 24 is originally before being cut. It is a sheet. Therefore, it is not necessary to prepare the paper pattern separately from the back sheet 25. Therefore, the storage bag 10 is realized by the front sheet 13 and the back sheet 25 in a two-layer structure, and the storage bag 10 can be manufactured at a lower material cost as compared with the three-layer structure.

The back sheet main body 24 of the storage bag 10 is made of high-quality paper or the like having no barrier layer, and the release sheet 26 of the back sheet main body 24 has a release layer 27 made of solvent-free silicone or the like impregnated on the surface. Here, since the back sheet main body 24 does not have a barrier layer, it is difficult to suppress excessive impregnation of the solvent-free silicone, but the release agent is excessively impregnated by irradiating with ultraviolet rays. Instantly dry before. Therefore, an inexpensive paper having no barrier layer can be used for the release sheet 27. Further, since the solvent-free silicone is instantly dried by ultraviolet rays, the storage bag 10 can be manufactured at once with one storage bag manufacturing apparatus without going through the procedure of drying the solvent-free silicone for a long time.

In the storage bag 10, the front sheet 13 is attached to the back sheet main body 24 via the adhesive layer 22 and the adhesive layer 19 without going through the procedure of drying the adhesive layer 22 and the adhesive layer 19 such as water-based glue. Since the back sheet main body 24 does not have a barrier layer, moisture permeability is maintained, and the adhesive layer 22 is naturally dried via the back sheet main body 24 even after the front sheet 13 is attached. Therefore, the storage bag 10 can be efficiently manufactured at once by one storage bag manufacturing device without going through the procedure of drying the adhesive before the storage bag 10 is formed.

Further, even if the front sheet 13 is a transparent film made of plastic having low moisture permeability, the adhesive layer 22 is naturally dried due to the moisture permeability of the back sheet main body 24, so that the front sheet 13 and the paper are not made of paper. The storage bag 10 can be realized from the back sheet main body 24 made of the product. Further, if the front sheet 13 is transparent, the object to be accommodated 1 accommodated in the accommodating portion 11 is transparent through the table sheet 13, so that the object to be accommodated 1 can be visually recognized from the outside.

In the storage bag 10, the sticking portion 12 composed of the sticking portion constituent surface portion 15 and the release sheet 26 is adjacent to the opening 20 of the housing portion 11. Therefore, by sticking the adhesive layer 22 to the box 2, the opening 20 can be closed by the sticking portion 12.

In the storage bag 10, since the back sheet 25 has the same shape as the storage portion constituent surface portion 14 of the front sheet 13, the entire storage portion 11 can cover the storage target 1. Therefore, it is possible to prevent the accommodation target 1 from falling off or being lost.

Since the storage bag manufacturing method does not involve a procedure of winding into a roll or aging, each procedure can be realized by one storage bag manufacturing device to manufacture the storage bag 10 at once. Further, since the pressure-sensitive adhesive constituting the adhesive layer 22 and the pressure-sensitive adhesive constituting the adhesive layer 19 are the same aqueous glue and are applied at the same time, the process can be simplified and the storage bag 10 can be manufactured. ..

An adhesive is applied to an intermediate portion 28 that is perpendicular to each of the end portions 16 and 17 and is formed between the end portions 16 and 17 to form an adhesive layer 19. In the laminated portion, when the front sheet 13 is attached to the back sheet main body 24 via the adhesive layer 22 and the adhesive layer 19, two places surrounded by the first end portion 16, the second end portion 17, and the intermediate portion 28. However, each becomes a storage area 21. Other configurations are the same as those of the storage bag 10.

The storage bags 210, 310, 410, and 510 described above also have the same effect as the storage bag 10.

In addition, in the storage bags 410 and 510, the storage portion constituent surface portion 14 and the back sheet 13 are adhered to each other via the adhesive layer 19 of the intermediate layer 28 formed between the ends of the back surface of the storage portion constituent surface portion 14. As a result, it has a plurality of accommodating areas 21. Therefore, the object to be accommodated 1 can be separately accommodated for each of the plurality of accommodation areas 21. Even in this case, since the storage bags 410 and 510 have a two-layer structure as a whole, the material cost is low as compared with the three-layer structure. Further, according to the storage bag manufacturing method, the adhesive is applied to the intermediate portion 28 at the same time in addition to the release layer 27 on the surface of the back sheet main body 24 and the end portions 16 and 17 excluding the storage region 21. Therefore, the process can be simplified to manufacture the storage bags 410 and 510.

In each of the above-described embodiments, the pressure-sensitive adhesive may be applied by, for example, a hot melt type or a solvent type. Further, the adhesive portion may be, for example, bonded with a liquid adhesive, or may be welded with a hot melt adhesive, heat seal, ultrasonic waves, or the like. Further, different kinds of pressure-sensitive adhesives may be used for the pressure-sensitive adhesive layer 22 and the pressure-sensitive adhesive layer 19. Further, the procedure of forming the adhesive layer 22 on the release layer 27 and the procedure of forming the adhesive layer 19 at each end on the surface of the back sheet main body 24 may be separately performed, and in which order. It may be ahead. Further, the position of the intermediate portion 28 in the storage bags 410 and 510 is arbitrary, and may be, for example, not in the middle but closer to one side, or may be formed diagonally. Further, the number of the intermediate portions 28 is also arbitrary. The size of the accommodation area 21 changes according to the arrangement of the intermediate portion 28, and the number of the accommodation areas 21 changes according to the number of the intermediate portions 28.
Paper may be used for the front sheet 13 in addition to the transparent film. For the back sheet main body 24, a sealing paper or a film having a barrier layer may be used. However, when a non-breathable material is used for both the front sheet 13 and the back sheet body 24, for example, when a film is used for both, a hot melt type adhesive is used, or when a solvent-containing adhesive is used. It is better to go through a drying process before laminating.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments. The present invention can be modified in various ways as long as it does not deviate from the matters described in the claims.
