Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a paper bag, and more particularly to a paper bag used in a store for paying purchased products and delivering them to customers.

[0002]

[Prior art]

 This type of paper bag is required to be as inexpensive and simple as possible for its purpose.One of them is to use a bank cord on both inner surfaces of the opening facing each other and the end of the bank string as the inner surface. It is widely used that it is sandwiched between and fixed by a holding paper adhered to the inner surface.

[0003]

[Problem to be solved]

 However, in such a conventional paper bag, since the opening is always open, foreign matter may enter from the outside during use, for example. In addition, if you store items that have a unique odor, such as foods that have been kept warm, the odor may leak to the outside while you are carrying it, which may be uncomfortable.

In the paper bag that needs to be simple and inexpensive as described above, it is not costly and strong to provide a normal sealing means such as a fastener in the opening. Appropriate.

Therefore, the present invention intends to improve the conventional paper bag as described above so that the opening can be sealed by an extremely simple means without increasing the cost.

[0006]

[Means for Solving the Problems]

 For this reason, in the paper bag of the present invention, a bank cord is respectively attached to both inner surfaces of the opening facing each other, and an end portion of the bank string is sandwiched between the inner surface and the inner surface to be fixed by a pressing piece connected to the inner surface. In the paper bag, each of the pressing pieces faces each other along the edge of the opening in a strip shape, and the surface of one pressing piece facing the other pressing piece is detachably attached to the other pressing piece. It is characterized in that an adhesive layer which can be attached is formed.

According to the present invention, when both pressing pieces facing each other in the opening of the paper bag are brought into contact with each other, both pressing pieces adhere to each other via the adhesive layer formed on one pressing piece. Since the adhesive force of the adhesive layer is relatively weak, both pressing pieces can be easily separated, and such adhesion and separation can be repeated. Since the two pressing pieces are opposed to each other along the strip-shaped edges of the corresponding opening edges, the attachment of these pressing pieces can substantially seal the opening of the paper bag. The above-mentioned tape with an adhesive layer that can be detachably attached to one side (hereinafter referred to as removable adhesive tape) is widely available on the market. By using this removable adhesive tape on one of the holding pieces used for holding the opening, it is extremely easy and does not substantially increase the cost compared with the conventional paper bag, and the opening portion is not increased. Can be sealed.

Normally, if the surface of the adhesive layer is detachably covered with a release paper, the opening will not be sealed by the adhesive layer even when the paper bag is stored in a folded state. If you open this paper bag, you can put items in through the opening, and you can remove the release paper only when you want to seal the opening, which is convenient.

[Embodiment of the invention]

 FIG. 1 is a perspective view showing a paper bag 1 according to an embodiment of the present invention. This paper bag 1 is made by bending a piece of paper material, and when expanded as shown in FIG. 1, the side plate portions 3a, 3b, 3c, 3d stand up from the four sides of the rectangular bottom plate portion 2, respectively. It has a rectangular parallelepiped shape, and an opening 4 is formed in the upper part.

Paper ridge cords 5 are fixed to the upper edge portions of the side plate portions 3a and 3b, respectively, and protrude upward in a U shape. The ridge cords 5 have both ends at the side plate portions 3a, 3b is fixed along the inner surface of 3b by pressing the pressing pieces 6 and 7 onto the inner surface. The holding piece 6 is a piece made of the same paper material as the main body of the paper bag 1, but the holding piece 7 is a piece made of the removable adhesive tape described above.

The bottom plate portion 2 has a relatively hard plate shape because the respective portions of the paper material forming the paper bag 1 are overlapped with each other here. Therefore, even if the product is easily broken, such as cake, it can be safely carried by placing it on the bottom plate 2 and storing it. Further, since the paper bag 1 is compactly folded and stored before use, a large storage space is not required. In this case, the levees 5 are folded in the bag.

FIG. 3 is a vertical cross-sectional view of the upper portion of the paper bag 1 in FIG. 1 taken along the line III-III, in which the thickness of each member is enlarged. As described above, the two bank strings 5, 5 are arranged along the inner surfaces of the side plate portion 3a and the side plate portion 3b, respectively, and are sandwiched between the side plate portion 3a and the holding piece 7 and between the side plate portion 3b and the holding piece 6. . The presser piece 7 and the presser piece 6 are fixed to the side plate portion 3a and the side plate portion 3b via an adhesive 8, respectively, and the bank cords 5 and 5 are firmly fixed to the side plate portions 3a and 3b.

The holding piece 6 is a simple piece of paper, and in the conventional paper bag, both of the bank strings 5 are fixed by such a holding piece. However, in the present invention, the other pressing piece 7 does not use a simple paper piece as described above, but uses the removable adhesive tape instead. That is, the pressing piece 7 is configured by integrally forming an adhesive layer 7b made of an adhesive on one surface of the base layer 7a made of paper or the like. The adhesive layer 7b is made to face the pressing piece 6 and the other surface is made of an adhesive. It is fixed to the side plate portion 3a by 8.

The above-mentioned pressure-sensitive adhesive does not fix the object permanently by fixing it like an ordinary adhesive, but always keeps the viscosity and can be repeatedly attached to and detached from the other party. Therefore, when the upper portions of the side plate portions 3a, 3b are pressed against each other from both sides, the pressing pieces 7 and 6 facing each other are attached via the adhesive layer 7b to seal the opening 4 (see FIG. 4) Since the pressing piece 7 and the pressing piece 6 can be separated with a relatively small force, the opening 4 can be easily opened again.

Since the pressing pieces 7 and 6 extend in a strip shape along the upper edges of the side plate portions 3a and 3b, the opening 4 can be sealed over almost the entire area of the upper edges as described above. As a result, it is possible to eliminate the above-mentioned problems such as the entry of foreign matter and the leakage of odor.

When the opening 4 is brought into the sealed state, as shown in FIG. 5, the upper portions of the side plate portions 3c and 3d have to be folded between the side plate portions 3a and 3b, so that the pressing piece 7 does not extend. The range is limited to the central section a, and the sections b and c on both sides are left unsealed. However, there is no problem because the gap between the side plate portions 3a and 3b in the sections b and c is extremely small by sealing the section a.

If the gap in the sections b and c becomes anxious, the gap can be sealed as shown in FIG. In the figure, 9 is an adhesive tape similar to the pressing piece 7. As shown in the figure, the adhesive tape 9 is folded in two with the side on which the adhesive layer 9a is formed facing inside, and the adhesive tape 9 is covered over the sections b and c respectively from above and adhered to the outer surfaces of the side plate portions 3a, 3b. It is preferable that the width of the adhesive tape 9 is substantially the same as the width of the sections b and c.

Before use, the paper bag 1 is folded as shown in FIG. 2, and since the pressing piece 7 and the pressing piece 6 are in contact with each other, at this time, the pressing piece 7 and the pressing piece 6 already have the adhesive layer 7b. It is inconvenient if they are attached via the adhesive, because they have to be detached each time they are used. Further, since the paper bag 1 is not necessarily sealed and used, various problems may occur if the adhesive layer 7b of the pressing piece 7 is exposed in the opening 4 in the open state.

In order to prevent this, as shown in FIG. 7, a release paper 10 may be applied to the surface of the adhesive layer 7b of the pressing piece 7 so as to be attached. In this way, even if the paper bag 1 is stored in a folded state, the opening 4 is not sealed by the adhesive layer 7b. It is convenient because it is possible to put items in from and to remove the release paper 10 only when it is desired to seal the opening 4.
