Description

[Detailed description of the invention] The present invention relates to a packaging bag made of a soft synthetic resin film, and more specifically, a packaging bag in which the opening is configured to be openable and closable with a lid piece with a pressure-sensitive adhesive band.
If the packaging bag is attached to a display mount, etc., or if the pressure-sensitive adhesive band on the lid piece loses adhesive strength and the lid piece cannot be closed, the lid piece may be replaced with the original one. This relates to a packaging bag that can be returned to a state where the lid can be closed.

Next, the present invention will be explained with reference to the embodiment drawings.
Reference numeral 1 denotes a bag body made of a soft synthetic resin film such as polyethylene terephthalate or polyvinyl chloride resin with an opening 2 formed on one side edge, and the bag body 1 is made by folding back two sheets of a wide soft synthetic resin film. The front film 3 and the back film 4 are stacked and heat-sealed at appropriate intervals in the longitudinal direction in a direction perpendicular to them.
The back film 4 of the bag 1 has a film that is bent toward the front film 3 side to close the opening 2 and is formed by heat-sealing and cutting the film at the heat-sealed location. A lid piece 5 is provided with a pressure-sensitive adhesive strip 6 for attachment to the front film 3.

The back film 4 of the bag body 1 has the opening 2
At one side edge of the side, attach an adhesive piece 7 of the same width as the one side edge,
It is provided so as to extend away from the bag body 1 in a direction perpendicular to this one side edge. A pressure-sensitive adhesive band 8 made of polyacrylic acid or the like is provided at the tip of the back side of the adhesive piece 7 in parallel with one side edge of the bag body 1. A cutting device is used to separate the adhesive piece 7 from the bag body 1 between the pressure-sensitive adhesive band 8 on the piece 7 and the bag body 1, that is, between the pressure-sensitive adhesive band 8 and the lid piece 5. A score line 9 is provided. Note that 10 is a cover body that covers the pressure-sensitive adhesive band 8 on the back side of the adhesive piece 7, and 11 is a product stored in the bag body 1.

With the above configuration, in order to store the product 11 in a packaging bag and display it hanging on a display mount, etc., first store the product 11 through the opening 2 of the packaging bag, and then store the product 11 in the packaging bag. The surface of the pressure-sensitive adhesive band 6 on the lid piece 5 of the packaging bag is attached to the front film 3 of the packaging bag.
Adhere it to the surface to close the opening 2, and then peel off the cover body 10 on the surface of the pressure-sensitive adhesive band 8 on the back side of the adhesive piece 7 of the packaging bag to expose the pressure-sensitive adhesive band 8, The pressure-sensitive adhesive strip 8 on the back side of the adhesive piece 7 can be attached to a display mount or the like. In this case, the packaging bag can be displayed by simply pasting the pressure-sensitive adhesive strip 8 on the back side of the adhesive piece 7 of the packaging bag onto a display mount, etc., and as a result, the packaging bag can be displayed very easily. It can be done easily. On the other hand, in order to sell the product 11 stored in the packaging bag, it is only necessary to cut the bag body 1 in the packaging bag at nine cut lines, so it is extremely easy to sell the product 11 by cutting the bag body 1. It is uruno.

Further, the packaging bag of the present invention can also store the product 11 in the packaging bag and display it by placing it on a display stand or the like, as described above. In this case, in order to observe the product 11 in the packaging bag, the customer or the like repeats opening and closing of the lid piece 5 of the packaging bag several times to remove the pressure-sensitive adhesive band 6 on the lid piece 5. When the adhesive strength is extremely reduced and as a result, it becomes impossible to close the opening 2 of the packaging bag with the lid piece 5, cut the adhesive piece 7 of the packaging bag at 9 cut lines and The cover body 10 on the surface of the pressure-sensitive adhesive strip 8 on the back side of the ivy adhesive strip 7 is peeled off to expose the surface of the pressure-sensitive adhesive strip 8, and then the adhesive strip 7 is attached as shown in FIG. In this case, the adhesive piece 7 may have the same width as the one edge of the opening 2 of the packaging bag. Therefore, the opening 2 can be reliably closed with the lid piece 5.

In the above embodiment, an adhesive piece 7 integral with the back film 4 was provided on one side edge of the opening 2 so as to extend in a direction away from the bag body 1. Instead, as shown in FIGS. 4 and 5, an adhesive piece integral with the back film 4 is attached to one side edge on the side of the opening 2 that is openable and closable with the lid piece 5 and one side edge on the opposite side. 7
may be provided in the same manner as described above, and instead of forming the adhesive piece 7 integrally with the back film 4 as in the above embodiment, the adhesive piece 7 may be formed integrally with the front film 3. Alternatively, the adhesive piece 7 is constructed separately from the front film 3 and the back film 4, and one side edge of the separate adhesive piece 7 is heat-sealed to the front film 3 or the back film 4. The adhesive piece 7 may be fixed to the bag body 1 by extending in a direction perpendicular to one side edge of the bag body 1 and away from the bag body 1.
, one side edge on the opening 2 side of the bag 1, or
Instead of providing one side edge on the side of the opening 2 and one side edge on the opposite side extending in the direction away from the bag body 1,
It goes without saying that the adhesive piece 7 may be provided on both one edge of the opening 2 and one edge of the opposite side of the opening 2.

In summary, the present invention constitutes a bag body having an opening on at least one side edge with a front film and a back film made of soft synthetic resin, and one of the front film or the back film is folded on the other film side. In a packaging bag comprising a lid piece that is bent to close an opening and is provided with a pressure-sensitive adhesive band for attachment to another film, the front film or the back film of the bag body has a lid that closes the opening. Attach a piece of adhesive the same width as the edge of one side.
On one or both of one side edge of the opening side, or one side edge of the opening side and one side edge of the opposite side,
The adhesive strip is provided to extend away from the bag in a direction perpendicular to one side edge of the bag, and a pressure-sensitive adhesive band is provided on the adhesive strip parallel to the one side edge of the bag, and the pressure-sensitive adhesive Since a cutting line is provided between the band and the bag body parallel to one side edge of the bag body, the product can be stored in the packaging bag through the opening and placed on a display mount, etc. If the pressure-sensitive adhesive strip of the lid piece loses adhesive strength and the lid piece cannot be closed anymore, the lid piece can be re-closed using the adhesive piece. It is possible to reliably restore the condition.

In addition, the present invention allows the adhesive piece to be attached to one side edge of the opening side,
Or, because it is provided on either or both of the one side edge on the opening side and the one side edge on the opposite side, extending in a direction perpendicular to the one side edge and away from the bag body,
The packaging bag of the present invention can be mass-produced and costs can be reduced by the so-called double-side sealing method, in which bags made of soft synthetic resin film are continuously manufactured.

In other words, in the double side sealing method, as is conventionally known, after a wide soft synthetic resin film material is transferred at a constant speed in the longitudinal direction, two sheets are stacked on top of each other, and two sheets are stacked on top of each other at appropriate intervals in the longitudinal direction. Since the bag is manufactured by heat-sealing both films by heat-sealing in the right angle direction and thermally cutting at the heat-sealed location, the adhesive piece is attached to one side edge on the opening side. If the adhesive piece is extended away from the bag body in the direction parallel to the bag body, that is, in the width direction of the bag body, the adhesive piece cannot be formed at the same time when manufacturing the bag body by the above-mentioned both side sealing method. Since the adhesive piece extends away from the bag in a direction perpendicular to one side edge on the opening side or one side edge on the opposite side, the width of the film material should be increased by the width of the adhesive piece, or It can be manufactured by a double-sided sealing method by supplying a belt-shaped film material of an appropriate width to form an adhesive piece and heat-sealing it in the transport direction.
