Description

  The present invention relates to a gusset bag with a handbag formed of a synthetic resin material and a manufacturing method thereof, and more particularly to a method of manufacturing a gusset bag with a handbag that can be manufactured by an automatic bag making machine.

  As a method and apparatus for manufacturing a gusset bag, for example, techniques described in Patent Document 1 and Patent Document 2 have been proposed.

  In the manufacturing method described in Patent Document 1, the side folded webs that constitute the horizontal gusset portion are interposed between the front and rear films, and the separate material webs that constitute the bottom portions are arranged in the conveyance direction of the front and rear films. In this method, the webs are welded while being conveyed in parallel to produce a gusset bag.

  On the other hand, the bag making machine for producing a gusset bag described in Patent Document 2 is an apparatus for producing a square bottom by folding a part of a belt-like film constituting a body part into two folds and guiding it to the bottom part. is there.

  In such a conventional method and apparatus for manufacturing a gusset bag, although it is possible to manufacture a gusset bag, it is necessary to manually perform any of the methods for providing a handbag in the gusset bag.

  That is, in these conventional gusset bag manufacturing methods and manufacturing apparatuses, the lateral gusset part and the bottom part are integrally sealed between the front and rear film, but are attached to the front and rear film. It was not considered at all to automatically provide a handbag to do.

  Therefore, the applicant previously proposed Patent Document 3 and obtained a patent. By this patent document 3, the manufacturing method of the gusset bag with a handbag which can automate the manufacture of the gusset bag with a handbag was implement | achieved.

  According to the manufacturing method described in Patent Document 3, a member constituting the handbag is formed separately from the bag main body and then connected to the side surface of the bag main body. Therefore, the position where the handbag is connected is connected to the portion of the side surface of the bag body that does not overlap the lateral gusset portion.

  Therefore, for example, in the case of a small gusset bag having a side width of only about 10 cm, the position of the handbag that can be connected to the gusset bag is limited to the inner side of the lateral gusset portion that overlaps the side surface of the gusset bag. As a result, even if a handbag is attached, the opening width has to be extremely small, and it has become inconvenient for adult fingers to insert.

  Therefore, the present invention can provide a handbag having an opening width equivalent to the side surface of the gusset bag without being formed at the position of the lateral gusset bag even by a small gusset bag by improving the manufacturing method of Patent Document 3. The object is to provide a method for manufacturing a hand-held gusseted bag.

In order to achieve the above-mentioned object, the first means in the present invention is handed to the synthetic resin film gusset bag 10 having the lateral gusset portion 13 and the bottom gusset portion 14 between the front surface portion 11 and the back surface portion 12. In the manufacturing method of the hand-held gusset bag with 15, the strip-shaped surface is formed by providing the horizontal gusset forming material 3 in which the strip film is folded into a flat tube shape to form the lateral gusset portion 13, and forming the surface portion 11. A horizontal gusset forming step 100 in which a pair of horizontal gusset forming materials 3 is arranged between the film 1 and a belt-like back film 2 that forms the back body portion 12, and a bottom film 4 that forms a bottom gusset portion 14 is arranged at the bottom. A horizontal gusseted handbag portion 13A extending in the direction of the handbag 15 is formed on the horizontal gusset forming material 3 of the bottom forming process 200 and the horizontal gusset forming process 100, and the belt-shaped handbag film 5 that forms the handbag 15 is formed. Horizontal ma A hand film is used when simultaneously bonding the front film 1 and the back film 2 via the hand laying process 300 disposed in an overlapped manner with the end portion of the hand portion 13A, and the horizontal gusset molding material 3 and the bottom film 4. When cutting the front film 1, the back film 2, and the bottom film 4, the horizontal gusset forming material 3, the horizontal gusset hand holding part 13A, and the hand holding film 5 And a cutting process 500 for cutting the above.

As a second means, in the hand arrangement step 300, the hand film 5 is formed when the front film 1 and the back film 2 are formed, or is formed separately from the front film 1 and the back film 2. That is.

According to the manufacturing method of the first aspect , the gusset bag 10 with the handbag 15 can be continuously formed. Moreover, manufacturing using an existing bag making machine is possible.

According to the second aspect , the hand-held film 5 can be procured from an arbitrary member in addition to the formation of the front film 1 and the back film 2.

  According to the present invention, the original object that a handbag having an opening width equivalent to the side face of the gusset bag can be provided without being formed at the position of the horizontal gusset even in a small gusset bag is achieved.

  The gusset bag according to the present invention is provided with a handbag 15 between a front surface portion 11 and a back surface portion 12 on a synthetic resin film gusset bag 10 including a lateral gusset portion 13 and a bottom gusset portion 14. As the synthetic resin material forming the gusset bag 10, for example, any synthetic resin material such as a film material obtained by laminating a nylon film on a polypropylene film, an LDPE film, an HDPE film, a PET film, or an aluminum vapor deposition film can be used. It is.

  The handbag 15 includes a horizontal gusset handbag 13A and a handbag film 5. The horizontal gusset hand portion 13A is a portion obtained by extending the end of the horizontal gusset portion 13 above the opening of the gusset bag 10, and the horizontal gusset portion 13 of the present invention is formed longer by the horizontal gusset hand portion 13A. (See FIG. 1).

  On the other hand, the handbag film 5 is formed of a synthetic resin film similar to the gusset bag 10 and joined to the end of the horizontal gusset handbag portion 13A. Therefore, when the handbag 15 is provided in the gusset bag 10, the handbag 15 is configured to continue from the lateral gusset portion 13 via the lateral gusset handbag portion 13A (see FIG. 1).

  The manufacturing method of the present invention includes a step of forming a horizontal gusset handbag portion 13A extending above the opening of the gusset bag 10 at an end portion of the horizontal gusset portion 13, and a handmade film made of synthetic resin at the end portion of the horizontal gusset handbag portion 13A. 5 (see FIG. 2). In particular, it has the following five steps. That is, the horizontal gusset forming process 100, the bottom forming process 200, the hand arrangement process 300, the hand bonding process 400, and the cutting process 500 (see FIG. 8).

  The horizontal gusset forming step 100 is a pair of horizontal gusset forming materials for forming the horizontal gusset portion 13 between the strip-shaped surface film 1 for forming the surface portion 11 and the strip-shaped back film 2 for forming the back body portion 12. 3 (see FIG. 2). This horizontal gusset molding material 3 is a folded film that is folded in half with the left and right ends of the rectangular film facing the center. Further, the bottom gusset portion 14 is folded by folding the lower end of the horizontal gusset molding material 3 at an angle of 45 degrees. A gusset is formed. When the gusset bag 10 is formed by cutting the horizontal gusset molding material 3 formed in this way at the center portion, two horizontal gusset portions 13 are formed. In the present invention, the upper end portion of the bottom portion 3 is extended to form the horizontal gusset hand portion 13A. The end portion of the horizontal gusset hand-held portion 13A is also folded at an angle of 45 degrees to sandwich the hand-held film 5 described later between the woven portions.

  The bottom part formation process 200 is a process of forming the bottom gusset part 14 from the bottom film 4 (see FIG. 2). In the illustrated example, the width of the back film 2 is formed wide. And in this bottom part formation process 200, the wide part is made into the bottom film 4, and it has distribute | arranged to the bottom part so that the bottom gusset part 14 may be formed, folding this bottom film 4. FIG. At this time, the bottom film 4 is folded in half by the guide mechanism 20 and is arranged so as to be superposed on the lower end portion of the horizontal gusset forming material 3 already arranged (see FIG. 1). It is also possible to form this bottom film 4 separately and attach it between the front film 1 and the back film 2.

  The hand arrangement process 300 is a process of disposing the belt-shaped hand film 5 forming the hand 15 on the horizontal gusset forming material 3 in which the horizontal gusset hand 13A is formed in a state of being overlapped with the end of the horizontal gusset 13A. (See FIG. 2). At this time, the end portion of the horizontal gusset hand-held portion 13A is folded at an angle of 45 degrees with the folding tool 30, and then disposed in the folded portion. Further, the hand-held film 5 can be formed when the front film 1 and the back film 2 are formed. Further, it can be formed separately from the front film 1 and the back film 2.

  The hand-joining step 400 is a step of joining the hand-holding film 5 and the horizontal gusset hand-holding portion 13 </ b> A when simultaneously joining the front film 1 and the back film 2 via the horizontal gusset molding 3 and the bottom film 4. (See FIG. 2). When an existing bag making machine is used, a gusset bag 10 is formed in which the entire peripheral edge is welded from the periphery of the gusset bag 10 to the handbag 15 from the lateral gusset handbag portion 13A.

  The cutting process 500 is a process of cutting the horizontal gusset molding material 3, the horizontal gusset hand-carrying portion 13A, and the hand-carrying film 5 when the front film 1, the back film 2 and the bottom film 4 are cut (see FIG. 2). . The hand-joining process 400 and the cutting process 500 may be performed simultaneously or separately.

  FIGS. 3 to 7 show means for changing the shape of the handbag 15 in the gusset bag 10 of FIG. 3 formed by the manufacturing method. That is, this FIG. 3 is the gusset bag 10 formed by manufacture using the existing bag making machine, and the upper edge of the handbag 15 is also joined. Therefore, the hatched portion shown in FIG. 4, that is, the welded portion of the upper edge of the handbag 15 is cut to reach the lateral gusset handbag portion 13A to remove the welded portion. Then, the handbag 15 and the horizontal gusset handbag portion 13A having a shape as shown in FIG. 5 are formed, and the handbag 15 can be formed longer. At this time, the side surface before being cut is as shown in FIG. 6, and the side surface after being cut has the shape shown in FIG. Thus, the shape of the handbag 15 attached to the gusset bag 10 can be arbitrarily changed.
