Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a product packaging bag that has a mold-proof bag integrally provided inside the bag body.

[Prior art]

2. Description of the Related Art Conventionally, as a packaging bag for storing foods, etc., it has been known to simultaneously store a mold-proof bag inside the bag body.

[Problem that the invention attempts to solve]

In the conventional type, a mold-proof bag is simply inserted inside the bag, so when the bag is opened and the food is eaten, the mold-proof bag escapes from the bag at the same time and the mold-proof bag escapes from the bag. There is a risk that young children may mistake it for food and put it in their mouths.

The above problem can be solved by fixing the mold-proof bag to the bag body, but the method of individually inserting and fixing the mold-proof bag to the bag body is not suitable for mass production of bags, and the cost of the bag increases. Especially since this type of bag is made continuously, it is necessary to consider inserting and fixing the mold-proof bag into the bag body on the production line, which is a problem. becomes.

[Means for solving problems]

In the present invention, the bag body itself as a product packaging bag is of the conventional mass-produced type that is manufactured continuously, and as shown in FIGS. 1 to 5, a synthetic resin film 1 is half-folded and polymerized. The front film 2 and the back film 3 that were polymerized together were sealed and cut at predetermined intervals in the longitudinal direction at the locations indicated by line A-A in FIG.
As a result, the bag body 4 has both side edges welded together.

On the other hand, as shown in FIGS. 6 and 7, the anti-mildew bag 5 stores alcohol venting agents 7 at intervals in the longitudinal direction in a tube 6 made of a vinylon film. The space between them is defined as a welded part 8, and an adhesive 9 is provided on the outer surface of the welded part 8.

Thus, the tube 6 is inserted and integrated into the bag body 4 during the bag making process of the bag body 4.

That is, the tube 6 is arranged along the film 1 that is the material of the bag 4, and the tube 6 is arranged so that the film is bent so that the tube 6 is inserted into the bag 4 at the film bending part.

In this state, the welded portion 8 of the tube 6 is adhered to the inner surface of the film with an adhesive 9 and positioned.

Therefore, if the half-folded and polymerized film 1 is then sealed and cut along the A-A line in the same way as in the conventional bag making method, both side edges of the bag body 4 and the welded part 8 of the tube 6 are simultaneously attached. By fusing and welding, both side edges of the mold-proof bag 5 are integrally welded with both side edges of the bag body 4.

[Effect]

According to the present invention, the bag body 4 can be mass-produced using conventional manufacturing methods.

In this bag-making process, if the tube 6 that will become the mold-proof bag 5 is inserted into the bent part of the film 1 as described above and the seal is cut in that state, the mold-proof bag 5 is integrated with the bag body 4. became
When food or the like is packaged in the bag body 4 and sold later, the mold-proof bag 5 will not accidentally escape even if the bag body 4 is opened.

In particular, in the present invention, when inserting the tube 6 into the folded part of the film 1, the tube 6 is positioned on the film 1 by the adhesive 9, so that the bag body 4 and the mold-proof bag 5 are connected at the time of the seal cutting. No mutual positional deviation occurs.

〔Example〕

One embodiment of the present invention will be described in detail based on the drawings.
As shown in Figures 4 and 5, the continuous synthetic resin film 2 is half-folded and polymerized along the line X-X in Figure 4, and the polymerized front film 2 and back film 3 are separated at a predetermined interval in the longitudinal direction. The bag body is then sealed and cut along the line A-A in FIG. 5, whereby both side edges are welded 10, 10.

The mold-proof bag 5 is manufactured as shown in FIGS. 6 and 7.

That is, a pair of tape-shaped vinylon films 6at6b are prepared, a paste-like alcohol release agent 7 is applied to the inner surface of one vinylon film 6a at intervals in the longitudinal direction, and the other film 6b is polymerized onto the film 6a. Then, by seal-cutting both side edges of both films, they are welded at 12°12, thereby forming a tube 6 as shown in FIG.

Therefore, in the tube 6, the film in the space between the alcohol dispersing agents 7 is the welded part 8.

Further, the pair of vinylon films 6a and 6b are located in the welded portion 8 and have an adhesive 9 applied to their outer surfaces.

Therefore, in the present invention, by using the tube 6 in the bag making process of the bag body 4, the mold-proof bag 5 is inserted and integrated into the bag body 4 at the same time as the bag making process.

That is, with the tube 6 disposed on one side of the folding line XX of the synthetic resin film 1 as shown in Figures 4 and 5, the synthetic resin film 1 is half-folded and polymerized as described above.

At this time, the welded portion 8 of the tube 6 is set to be located at the cut seal portion A-A of the film 1.

At this time, the tube 6 is fixed in a predetermined position on the synthetic resin film 1 by an adhesive 9.

Therefore, if the front and back films 2, 3 polymerized from this state and the welded part 8 of the tube 6 sandwiched between them are simultaneously sealed and cut along the A-A line, the result will be as shown in the first to third figures. The anti-mildew bag 5 separated from the tube 6 is inserted into the folded portion of the front and back films 2 and 3, and the seal cut cuts both sides of the anti-mildew bag 5 and both edges of the bag body 4. They are integrally welded 10,10.

During this seal cutting, since the tube 6 is fixed in position by the adhesive 9, the mold-proof bag 5 will not be misaligned with respect to the bag body 4 due to resistance during cutting.

〔effect〕

As a result of the present invention configured as described above, the mold-proof bag 5 has a structure similar to that of the bag body 4.
Since the mold-proof bag 5 is integrally fixed inside the bag 4, even when the purchaser opens the bag 4 after storing food, etc. in the bag 4 and offering it for sale, the mold-proof bag 5 is removed from the bag 4. There is no risk of it accidentally escaping and getting into the mouths of children, etc.

In particular, in the present invention, in the bag making process, the tube 6 is simply placed continuously on the film 1 of the continuous bag material, and then cut along the line A-A as in the conventional bag making process. The mold-proof bag 5 is integrated into the bag body 4 by simply sealing it, and there is no need for major changes to the bag-making process, and the conventional bag-making process can be used as is, so it has already been implemented. It has the advantage that it can be easily applied to mass-produced bags.

Furthermore, although the tube 6 has a considerable thickness because it accommodates the alcohol dispersing agent 7, the adhesive 9 is applied to the film 1 of the bag material during the bag making process. The part to be welded 8 is accurately positioned and fixed,
In particular, since the both side edges of the bag and the welded part of the mold-proof bag which are seal-cut along the line A-A are positioned and fixed to each other, the bag body 4 and the mold-proof bag 5 are separated by the seal cut. There is no misalignment, and the finish is good.
Therefore, from this point of view as well, there is an effect that is suitable for mass production.
