Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a product packaging body formed of a mount and a bag body, and the bag body is opened and closed by a folding flap inserted into an insertion opening. .

(Prior art) In a product packaging body formed of a mount and a bag body, in which the bag body is opened and closed by folding, an adhesive layer is provided on the folding flap, and the adhesive layer is inserted through the adhesive layer. There is one that opens and closes the bag.

In addition, there are also bags that open and close by folding the bag into a slot.

(Problems that the invention aims to solve) Products with an adhesive layer on the folding flap may adhere to the adhesive layer when taking the product in or out of the bag, or the adhesive layer may attract dust or deteriorate over time. There is a problem that the adhesion force is reduced.

If the folding piece is inserted into the insertion slot, there is no problem due to the adhesive layer.

However, in order to form the outlet, it is necessary to, for example, attach a band to the bag and use the gap between the bag and the hand as the outlet, which requires new materials and manufacturing processes. This required high production costs.

In view of the above, an object of the present invention is to provide a fold-in insert type product packaging body in which the insertion opening for inserting the fold-in flap is formed without requiring any new members or manufacturing process, and can be manufactured at low cost. .

(Means for Solving the Problems) The technical measures taken by the present invention to solve the problems of the prior art are characterized by a folded and polymerized thermal weld at the bottom of a mount made of a heat-fusible sheet. The synthetic resin films are stacked and the edges on both sides are heat-sealed together with the mount to form a bag, and a gap is formed between the lower edge of the mount and the lower edge of the bag, and the gap is It is located at the point at the top of the folding mount, which is said to be the insertion opening.

(Function) If a bag is formed by welding both sides of the thermofusible synthetic resin film that has been folded and polymerized together with the mount, a folding insertion opening will be formed, and a new method for forming the insertion opening will be created. No parts or manufacturing processes are required.

(Example) Hereinafter, embodiments of the present invention will be described based on the drawings.

Figures 1 and 2 show a fold-in insert type product package;
It is formed by a mount 1 and a bag body 7.

The mount 1 is made of a rectangular heat-fusible sheet.

As the heat-fusible sheet, synthetic paper, a thick synthetic resin film mount, a sheet of paper laminated with a synthetic resin film, a sheet of paper coated with a synthetic resin, etc. are suitable.

The bag body 7 is formed by folding and polymerizing the heat-fusible synthetic resin film 2 and attaching it to the lower part of the mount 1, and heat-welding both side edges 15, 15 of the film 2 together with the mount so that the top end is open. It is.

The vertical dimension of the bag body 7 is approximately a little less than 1/2 of the vertical dimension of the mount 1.

Further, the lower edge of the bag body 7 is along the lower edge 10 of the mount 1, and is formed into a so-called gusset bottom 8 having a substantially wave-shaped side cross section.

Then, by molding the bag body 7, the lower edge of the bag body 7 and the mount 1
A gap is formed between the lower end edge 10 of and the gap serves as an insertion opening 16.

Next, 3 in the figure. 4. 5.6 is a fold formed on the upper part of the mount 1 over the entire width direction.

As a result, the upper part of the mount 1 is bent to form a crease 12 that closes the opening of the bag body 7, as shown by the chain line in FIG.

Here, the lowest fold line 3 is approximately along the opening edge of the bag body 7, and each fold line 4 above the fold line 3 is substantially along the opening edge of the bag body 7. 5. 6 corresponds to the widthwise edge spacing of the bag body 7.

Then, the space between the uppermost fold 16 and the upper edge 9 of the mount 10 is an insert piece 12a of the fold M12, and the insert piece 1
2a is inserted into or removed from the insertion port 16 to open and close the fold 12.

Note that notches 11 are provided at both widthwise ends of the upper edge 9 of the mount 10.
11, the insertion piece 12a can be easily inserted into the insertion opening 16.

According to the above-mentioned fold insertion type product package, the insertion opening 16 of the fold 12 is formed when the bag body 7 is formed, and no separate material or manufacturing process is required for forming the insertion opening 16. Therefore, manufacturing costs can be reduced as much as possible.

(Effects of the invention) According to the invention, if a mount and a bag are formed from a heat-fusible sheet and a synthetic resin film, a gap will be formed at the top of the mount, which will serve as the insertion opening. Therefore, there is no need for additional materials or manufacturing processes for forming the insertion port, and manufacturing costs can be reduced as much as possible.
