Description

[Detailed Description of the Invention] The present invention relates to improvements in plastic film product packaging bags for packaging products such as socks and underwear for display in stores.

In this type of product packaging bag, one piece of the bag opening is bent and a core board made of cardboard is attached to the sealing part to provide stiffness to the sealing part, and the core is reinforced. It is well known that the board is also used as a printing mount on which product names, manufacturers, etc. are printed.

By the way, in the past, means such as staples or glue have been commonly used to fasten the core plate, but such fastening methods not only require troublesome work, but also tend to come off easily, and do not look good. The problem was that it was not easy to keep it in the correct condition. In addition, in recent years, as inventory management is performed using computers, display boards such as labels with necessary information written on them are affixed to products, and when the product is sold, the display board is removed from the product and stored. However, conventional product packaging bags have not taken this point into consideration at all.

The present invention was developed to improve the above-mentioned drawbacks of the conventional technology, and its feature is that a piece of the bag opening of the bag body made of plastic film is extended to form a bent sealing piece. , an auxiliary bag portion having an auxiliary bag opening with one end open is formed on one surface of the bent sealing piece, and a core plate with various markings is removably inserted into the auxiliary bag portion from the auxiliary bag opening. at the point,
In particular, the display board is removable and can be inserted to meet recent demands.

Embodiments of the present invention will be described below based on the drawings.
First, the first embodiment will be explained with reference to FIGS. 1 to 4. A transparent plastic film is folded in half and both ends are heat-sealed 1 and 2 by thermal cutting to open a bag opening 3 at the top. The tip of the bent sealing piece 5, which constitutes the bag body 4 and is formed by extending one piece of the bag opening 3, is placed inside (the other piece 6 of the bag opening 3).
By folding the two ends to the same side (the same side as the bag body 4) and heat sealing both ends 7 and 8 at the same time as the ends 1 and 2 of the bag main body 4, an auxiliary bag part 10 is formed that opens an auxiliary bag mouth part 9 at the lower part, and A pressure-sensitive adhesive 11 is applied to one side of the tip of the auxiliary bag portion 10, and a release paper 12 is temporarily attached onto the adhesive 11.

After making bags as described above, products such as socks and underwear are put into the bag body 4 from the bag opening 3, and the core plate 13 made of cardboard, synthetic paper, etc. (This corresponds to the attached label, but it also serves as reinforcement for the folded sealing piece 5, so it is simply referred to as a core plate.) Insert it into the auxiliary bag part 10 from the auxiliary bag opening part 9, peel off the release paper 12, and apply the adhesive. 11 is exposed, the lower part of the auxiliary bag opening part 9 of the bent sealing piece 5 is bent, and the auxiliary bag opening part 9 is opened by this bent part 14.
At the same time, close the tip of the auxiliary bag part 10 to the bag opening part 3.
It is superimposed on the outer surface of the other piece 6, and this overlapping portion is bonded with the adhesive 11. In this way, the bag opening 3 can be sealed at the same time that the core material 13 is finished being attached.

When the packaging bag is configured in this way, the core plate 1
3 is completely covered with the auxiliary bag opening 9 in the auxiliary bag part 10 which is closed by the bending part 14 in an aligned state and in a stationary and fixed state, and the core plate 13 is not likely to be removed and is aligned. It is possible to obtain a good-looking wearing condition. Furthermore, when attaching the core plate 13, the core plate 13 can be attached by a simple operation of inserting the core plate 13 into the auxiliary bag portion 10 and bending the lower part of the bag opening 9 of the auxiliary bag portion 10. At the same time, the bag opening 3 of the bag body 4 can be sealed.

The core plate 13 may be printed with various indications such as a product name and a manufacturer's indication in advance so that it can be seen from the outside of the auxiliary bag portion 10.

Furthermore, in order to make the packaging bag capable of being hung, a hole 15 for inserting a hanging hook may be opened in the auxiliary bag portion 10 so as to pass through the core plate 13, as shown in the figure.

Next, the second embodiment shown in FIGS. 5 to 8 will be described. On the inner surface of the folded sealing piece 5 of the bag body 4, which has the same structure as the first embodiment, there is a A strip film made of plastic film 16
The overlapping parts of both ends of the film strip 16 and the ends of the folded sealing piece 5 are heat-sealed 7 and 8 by thermal cutting, and the lower end of the film strip 16 inserted into the bag opening 3 is sealed. By heat-sealing 18 the overlapping part between 17 and the inner surface of a piece of bag opening 3,
An auxiliary bag part 10 is constructed with an auxiliary bag mouth part 9 open at the top, a pressure-sensitive adhesive 11 is applied to the inner surface of the tip of the folded sealing piece 5, and a release paper 1 is applied on top of the adhesive 11.
Temporarily attach 2. In addition, during the above-mentioned bag making, the heat sealing 18 of the lower end of the strip film 16 is performed in the step before heat sealing 1 and 2 on both ends of the bag body 4, and after completing this heat sealing, the lower ends of the bag body 4 are heat seal 1,
2 and heat sealing 7, 8 of both ends of the strip film 16 are performed simultaneously.

After the above bag making, the product is loaded into the bag body 4 through the bag opening 3, the core plate 13 is inserted into the auxiliary bag opening 9 through the auxiliary bag opening 9, and the release paper 12 is peeled off to expose the adhesive 11. After that, the auxiliary bag part 10 is folded in half along with the core plate 13, and the tip of the folded sealing piece 5 is overlapped on the outer surface of the other piece 6 of the bag opening part 3, and this overlapping part is joined with the adhesive 11. For example, when the auxiliary bag opening 9 is closed and the core plate 13 is completely enclosed within the auxiliary bag 10, the bag opening 3 is sealed.

When the packaging bag is configured in this way, the core plate 1
Since the double folded structure of 3 is obtained, the reinforcing effect can be increased when the core plate 13 made of the same thickness and material as in the first embodiment is used, and the hole 15 for inserting the hanging hook can be assisted. The opening can be opened at the bent part of the bag part 10, and a well-balanced hanging state can be obtained. Further, the core plate 13 is completely provided in the auxiliary bag portion 10 so that it cannot be removed and the appearance can be improved, and the core plate 13 can be easily attached, as in the case of the first embodiment. Incidentally, as shown in the figure, the bent portion of the core plate 13 may be provided with a crease 19 formed by a cut to facilitate bending.
