Description

[Detailed description of the invention] This invention relates to improving the hanging structure of bags, more specifically bags for packaging miscellaneous goods, textile products, etc., especially bags for hanging and displaying. A backing plate made of base paper is sealed and integrated on the tongue piece formed on the upper part as a sealing piece, and a hook (hanger) can be created by providing a hook-shaped hanging cut or notch directly on this backing plate part. It does not require any work to install the hook, which greatly simplifies the manufacturing process and allows for significant cost reductions.
Moreover, it is an object of the present invention to provide a completely new bag in which the strength of the hanging portion is maintained.

Conventionally, as a hanging structure for this type of bag, a method of inserting and locking a hanger into a hanger mounting hole as disclosed in Japanese Utility Model Application Publication No. 79514/1983, or a method of inserting and locking a hanger into a hanger mounting hole, as disclosed in Japanese Utility Model Application Publication No. 49-1
A method of providing a notch and inserting a hanging rod into the notch so that it can be torn off, as in the device disclosed in Japanese Utility Model Application Publication No. 35611 of 1982, and a method of suspending as in the device disclosed in Japanese Utility Model Application Publication No. 35611-1983. This can be roughly divided into two methods: drilling a hook hole for hanging and inserting a hanging rod into the hook hole.

However, when using hangers as in the first method, attaching the hangers is complicated and production efficiency is low, and the hangers have to be prepared separately, making the bag expensive. there were.

In the second case, since the bag is torn off, once it is torn, it cannot be hung from the hanging rod again, and therefore is not suitable as a hanging structure for display bags.

In the third case, a considerable number of bags are suspended from the hanging rod at the same time, so if you want to take out the bag on the back side, you have to take out all the bags on the front side from the hanging rod. Due to its inconvenience, it was not suitable for display as in the second case.

Therefore, the first hanger (hook) method is generally used, but as mentioned above, this method has serious drawbacks in terms of manufacturing and cost of the bag.

This idea eliminates all of these conventional drawbacks and creates a bag with a hanging structure that is ideal for display hanging bags and can be manufactured at low cost. In a bag body that has a hanging part formed integrally with one piece of the opening of the main body as an extended tongue part and a backing plate made of base paper sealed between the tongue part and the tongue part, the hanging part when sealed. A notch or notch is formed on both the front and back sides of the top edge for hanging rods.

The specific configuration thereof will be explained below according to an embodiment shown in the drawings.

1 is a packaging body made of a plastic film, for example, a thermoplastic synthetic resin such as polypropylene; the folded portion of the plastic film is the bottom of the packaging body, and the - piece is extended from the opening 2 to form a tongue piece as a sealing piece. Part 3 is formed.

4 is coated in advance with a heat sealing agent 5 made of goza synthetic resin that can be sealed by low-temperature heating on the entire outer surface, preferably polypropylene, which is the same material as the film of the housing body 1 and has excellent sealing strength, and on the entire inner surface. It is a backing plate made of cardboard laminated with heat-weldable thermoplastic synthetic resin 6, such as polypropylene, and is arranged so that its lower end is located within the main body 1 directly below the opening.

This contact plate 4 is made by polymerizing the outer heat sealing agent No. 5 on the inside of the tongue portion 3, and when it is passed through a heating roll during manufacturing, it is heat-sealed onto the tongue portion 3 at a low temperature and becomes integral.
Thereafter, when both inner side ends of the backing plate 4 are thermally welded at the same time as the mounting body 1, the inner lower end portions of both sides of the backing plate 4 are heat welded to the mounting body 1 at the same time, and welded portions are formed at both ends.

Reference numeral 7 denotes a hanging portion constituted by the contact plate 4 that is integrally heat-sealed onto the tongue portion 3 of the mounting body 1 as described above;
Fold line 9 from the approximately central upper end 1' of the packaging body (hanging part) when the tongue piece 3 of the packaging body is folded from the fold line 9 and sealed
Shown are hook-shaped hanging notches formed in a substantially J-shape by penetrating the contact plate 4 on both the front and back sides of the figure.

Reference numeral 10 denotes an adhesive layer having a mold release material 11 provided on the inner upper part of the plate 4, and when the product is sealed and hung, dust from the hanging notch 8 may enter into the packaging body 1 and cause damage to the product. As shown in FIG. 3, the opening 2 is sealed to prevent it from adhering to the surface.

Since this device is constructed as described above, when the product A such as socks is inserted through the opening 2 of the packaging body 1, the tongue piece 3 is folded from the crease line 9, and the bag is sealed, when the bag is hung. , when the notch 8 is inserted into the hanging rod B for displaying products as shown in FIG. The film and the backing plate 4 are heat-sealed and integrated, so
The film does not come loose from the backing plate 4 during hanging.

In addition, since a notch is formed from the upper end of the bag body, it is extremely easy to remove the bag from the hanging rod when it is suspended, and at the same time, it is also easy to hang the bag once it has been removed. be able to.

Note that the shape of the notch opening is not limited to the hook-shaped shape as in this example, and the notch width of the notch opening does not necessarily have to be the same up to the tip as in this example; only the tip may be large. It may also be the caliber.

Moreover, the depth from the upper end edge of the suspension part to the suspension rod insertion part at the tip of the notch opening may be freely adjusted according to the weight of the stored products.

Furthermore, Fig. 4A shows the side through which the suspension rod B is inserted, that is, the third
A reinforcing plate 13 is attached to the upper edge on the left side of the figure to further maintain the strength of the suspended portion.

Further, the opening in the figure is made by pasting a similar reinforcing plate 13' from the inside of the backing plate 4 at the same position as described above.

FIG. 5 shows a horizontal elongated hole 12 for suspending a product A such as socks, which is formed at the lower end of the backing plate 4, which is disposed so that its lower end is located inside the packaging body.

Due to the formation of the elongated hole 12, when the product A is suspended, the product A is always stored in the main body in an orderly manner without any unsightliness caused by falling off or the like.

As shown above, this idea is to integrally heat-seal a cardboard backing plate to the tongue piece formed by extending one piece of the opening of the housing body, to form a hanging part, and to this hanging part. Since it has a notch for hanging, there is no need for a separate hanger (hook) like in the past, and there is no need to install a hanger at all, making the bag extremely easy and inexpensive to manufacture. This is an advantage that can be achieved.

Moreover, since the notch opening is formed from the upper end of the main body (hanging part), it can be hung from and removed from the hanging rod as with conventional bags with hangers. In contrast, we have achieved the optimal effect as a hanging structure for display without requiring hangers.

Furthermore, since the tongue part is integrally provided with a plate that is sealed over the entire surface, the strength of the hanging part made of cardboard can be maintained, and it can handle hanging products of considerable weight, while also being integrated. The seal prevents the cardboard from separating from the film, resulting in an extremely excellent appearance.

This effect is particularly noticeable when the backing board is made of cardboard.

In addition, the overall structure is simple, easy to manufacture, inexpensive, and suitable for mass production, which has great practical effects.
