Description

  The present invention relates to a method of manufacturing a horizontal gusset bag with a hanging header formed of a synthetic resin material and a horizontal gusset bag, and particularly with a hanging header that can be formed into a blister pack using a thin film. The present invention relates to a method for manufacturing a horizontal gusset bag.

  A blister pack is a packaging container in which a back plate printed with a product name etc. is joined to a transparent storage section such as polyethylene terephthalate (PET), polyvinyl chloride (PVC), polystyrene (PS), etc. It is. In general, when displaying at a storefront, a locking hole is opened in a header formed in the upper part of the back plate, and a bar-shaped support is inserted into the locking hole to display a product.

  In this blister pack, since a planar transparent sheet is formed into a three-dimensional storage part, a relatively thick sheet material is used for the storage part. Therefore, the material cost becomes high, and a large amount of carbon dioxide is discharged at the time of disposal. Therefore, at present, there is a demand for a package made of a film material that emits less carbon dioxide and has a lower material cost because of a demand for preventing environmental destruction.

  Patent Document 1 describes a packaging container that is formed into a blister pack using a thin film material. According to this method for manufacturing a packaging container, first, a storage part is formed by a method such as embossing a roll-shaped main body film and slowly sucking it with a vacuum. Next, an elongated content such as a syringe is stored in the storage unit, a cover film is covered on the stored main body film, and both end edges of the storage unit are vertically sealed. Next, the Z-shaped folded part is formed by pushing the vicinity of the center of both side walls of the storage part from both sides, and after side sealing from the top of the lid film, the vertical seal is cut and the contents are one by one This is a method of forming a packaging bag in which an object is stored.

  Patent Document 2 describes a bag having a gusset. This bag relates to a so-called pillow wrapping bag in which a horizontal gusset is formed, and a horizontal gusset is formed on both longitudinal edges of the main portion made of a band-shaped seal, and another band-shaped seal is superposed on the opening of the main portion. Thus, a bag body is formed.

  According to the manufacturing method described in Patent Document 1, the storage portion is formed by a method such as embossing a roll-shaped main body film and slowly sucking it with a vacuum. However, when embossing a thin film, there is a risk that corners and the like may be damaged, and extremely precise and careful work is required. Moreover, since the cover film is covered on the stored main body film, it is possible to form a header such as a blister pack, but since a mold for embossing is used, the manufacturing cost is remarkably increased. There were also challenges.

  On the other hand, in the packaging bag described in Patent Document 2, although a thin film can be used for packaging as in the so-called pillow packaging, a locking hole is opened in a header such as a blister pack. It was difficult in terms of strength to display a product by inserting a support through the hole.

  In addition, when any packaging bag is formed with a header such as a blister pack, the horizontal gusset extends to the header, resulting in a step in the header. However, this header has become an important advertising medium with a photocopy and design that forms a catch phrase for the product and the impression of the product. If there is a step in this header, there is a risk that it will cause a significant hindrance to the advertising effect. There is.

  Therefore, the present invention was created to solve the above-described problems, and provides a method for producing a horizontal gusset bag with a hanging header, which can form a blister pack-like header packaging bag at low cost using a thin film material. With the goal.

Is possible.

  The horizontal gusset bag of the present invention is a horizontal gusset bag in which a suspension header 21 provided in a blister pack is formed, and can be formed of a film material that is thinner than the blister pack. That is, it includes a storage portion 10 formed of a thin transparent film material, and a film material suspension lid 20 joined to the back opening of the storage portion 10. The header 21 reinforced with the reinforcing material 3 is provided on the upper end side (see FIGS. 2, 5, and 8). A locking hole 22 is opened in the header 21, and a bar-like support or the like is inserted into the locking hole 22 to suspend and display a product.

  The storage part 10 is formed with horizontal gussets 11 along both longitudinal side edges of the belt-like film 1 (see FIGS. 2, 5, and 8). On the other hand, the suspending lid 20 is formed by sticking the reinforcing material 3 to the roll film 2 forming the suspending lid 20 to form a suspending header 21. And these accommodating part 10, the lid 20 for suspension, and the header 21 are integrally joined.

  The manufacturing method of the present invention includes a storage portion forming step 100, a positioning step 200, a header forming step 300, a vertical sealing step 400, and a cutting step 500 (see FIGS. 1, 4, and 7).

  The storage portion forming step 100 is a step of cutting the storage portion 10 in which the folded horizontal gusset 11 is formed along both longitudinal side edges of the belt-like film 1 into a predetermined length (see FIGS. 1, 4, and 7). In the illustrated example, the horizontal gusset 11 is formed by folding the belt-like film 1 from the left and right with a plurality of pressing rolls 30. Moreover, the strip | belt-shaped film 1 which formed the horizontal gusset 11 is cut | disconnected by a predetermined | prescribed cutting machine (not shown), and the accommodating part 10 is provided. The storage unit 10 at this time is in a state where the top and bottom and the back are opened.

  The positioning step 200 is a step of placing the back opening side of the storage unit 10 on the roll film 2 and temporarily fixing the position of the storage unit 10 (see FIGS. 1, 4, and 7). In the illustrated example, a plurality of storage portions 10 formed to have a predetermined length are placed side by side, and the longitudinal side edge portions of the main bodies 10 are bonded by positioning seals 5 to fix the storage portions 10. .

  The header formation process 300 is a process of sticking the reinforcing material 3 to the upper end portion of the roll film 2 to form the suspension header 21 (see FIGS. 1, 4, and 7). In the illustrated reinforcing material 3, the upper end portion of the roll-shaped film 2 that forms the suspension lid 20 is folded back to integrally form the roll-shaped film 2 and the reinforcing material 3.

  The vertical sealing process 400 is a process of welding the longitudinal both side edges of the storage unit 10 to the roll film 2. By this process, the temporarily fixed storage 10 is heat-sealed to the roll film 2 (see FIGS. 1, 4, and 7).

  The cutting process 500 is a process of cutting the roll film 2 to form a horizontal gusset bag with the header 21 (see FIGS. 1, 4, and 7). In the example of illustration, the lid 20 for suspension with the header 21 is formed by heat-cutting the roll-shaped film 2 so that it may orthogonally cross with respect to a longitudinal direction.

  The horizontal sealing step 600 is a step of welding the lower end portion of the storage unit 10 after the vertical sealing step 400. By this step, a packaging container for storing the stored items from the upper opening of the storage unit 10 can be formed. Thus, it can be set as the opening part which selects either the upper-lower opening part of the accommodating part 10, and accommodates a stored item.

  For example, as shown in FIG. 1, when welding is performed so as to cover the upper opening of the storage unit 10 in the header forming step 300, a packaging container for storing the stored items can be formed from the lower end of the storage unit 10 (FIG. 2). 3, FIG. 10, FIG. 12). In this case, in the header forming step 300, it is also possible to form the suspension header 21 by sticking the reinforcing material 3 as another member to the roll-shaped film 2 positioned on the upper portion of the storage unit 10 ( (See FIG. 11).

  On the other hand, as shown in FIG. 4, when the reinforcing material 3 is welded so as to cover only the roll-shaped film 2 above the upper opening of the storage unit 10 in the header forming process 300, the stored items are opened from the upper opening of the storage unit 10. Can be formed (see FIGS. 5 and 6). In this case, after the vertical sealing step 400, the lower end portion of the storage unit 10 is welded by the horizontal sealing step 600 to form the bottom portion 13 (see FIGS. 4, 5, and 6).

  Further, the bottom gusset arrangement step 700 is a step for forming the bottom gusset 12 in the storage unit 10 (see FIG. 7). That is, the lower end portion of the storage portion 10 is folded, and the bottom gusset material 4 is welded to the folded end portion to form the bottom gusset 12. By this process, a bottom gusset 12 is formed at the bottom of the storage portion 10, and the storage portion 10 is formed in a gusset bag shape having a lateral gusset 11 and a bottom gusset 12. In the illustrated bottom gusset forming step 700, after the positioning step 200, the bottom end device 40 is pressed against the lower end portion of the main body 10 to fold back the lower end portion, and the belt-like bottom gusset material 4 is folded in half. Is arranged. Then, after the vertical sealing step 400, the bottom gusset 12 is also bonded at the same time in the horizontal sealing step 600.

  13 to 16 show another embodiment of the present invention. In this embodiment, during the positioning step 200, the lower end portion of the storage portion 10 is disposed so as to protrude from the lower end portion of the roll film 2 (see FIG. 13). After passing through the vertical sealing step 400 and the cutting step 500 in this state, the lower end portion of the storage unit 10 is opened and extended downward (see FIGS. 14 and 15). Therefore, after storing the stored item from the lower opening, the lower end portion of the storing unit 10 is folded back to the roll-shaped film 2 side and bonded with the sealing seal 6 (see FIG. 16).

  17 to 19 show another embodiment of the present invention. In this embodiment, an adhesive tape mounting step 800 for mounting the adhesive tape 7 on the upper end of the roll film 2 is provided (see FIG. 17). And after the header formation process 300, the flap 8 with the adhesive tape 7 which covers the upper opening part of the accommodating part 10 is formed (refer FIG. 18). Therefore, after storing the stored item from the upper opening, the flap 8 is overlaid on the upper end of the storing unit 10 and bonded with the adhesive tape 7 (see FIG. 19).

  The present invention is used as a lateral gusset bag with a hanging header formed of a synthetic resin material. At this time, the horizontal gusset bag is not limited to the shape of the illustrated example, and the header can be arbitrarily changed. Moreover, the structure of the apparatus used with the manufacturing method of this invention is not limited to illustration. Furthermore, the use, shape, size, material, etc. of the horizontal gusset bag can be freely changed without changing the gist of the present invention.
