Abstract

PROBLEM TO BE SOLVED: To provide a packaging bag capable of enduring a long term suspension even when the bag houses a heavy item. SOLUTION: A packaging bag is constructed by heat-sealing circumferences of two opposing sheet materials and is provided with a hole 11 for suspension. A hole 11 for suspension is formed in a portion where two sheet materials are heat-sealed with a resin-made disk plate 13 being clamped between them and are integrated into one body. Since the disk-like resin plate 13 is strongly integrated into one body between the two sheets by means of heat-sealing, the disk plate itself can not be torn off from the bag even if the bag is suspended for a long term.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging bag that can be hung in a state of containing contents at the time of store display or use.

[0002]

2. Description of the Related Art Conventionally, a liquid material exceeding a certain capacity is
For example, it is often sold in 500 ml or 1 L size PET bottles or blow bottles. In addition, powder such as wheat flour that exceeds 0.5 kg when stored is often sold in flat bags or square bottom bags. In such a sales form, the containers or bags for packaging are sold side by side on display shelves, so that the display place is limited.

On the other hand, as a form that can be installed and sold in addition to the display shelves, a hanging type package which is hung and displayed on a hook or the like is known. As the hanging type package, (1) one in which a hole is directly formed in a heat-sealing part of a vinyl bag, (2) one in which a metal eyelet is attached around the hole formed in the sealing part, (3) ) It is known that a mount, which is a separate body, is attached to the upper part of the bag to form a hanging hole in the mount.

However, the conventional example of the above (1) has a problem that the hole portion is torn when the contents are heavy or are hung for a long time. Even in the case of the above (2) in which the eyelet made of metal is provided in the hole, the problem that the eyelet is cracked when the contents are heavy and the problem that the eyelet itself is torn off from the hole remains. Further, in the case of the above (3), since it is necessary to attach the mount to the packaging bag, there is a problem that the number of manufacturing processes increases and the cost increases.

[0005]

Therefore, a technical problem to be solved by the present invention is to provide a packaging bag which can endure hanging for a long time even when a heavy object is stored therein. is there.

[0006]

[Means, Actions and Effects for Solving the Problems]
The present invention has been devised in order to effectively solve the above problems, and provides a packaging bag having the following features.

The packaging bag of the present invention is constructed by heat-sealing the periphery of two sheet materials facing each other, and is provided with a hanging hole. For the hanging holes, use the resin plate material described in 2 above.
It is formed in an integrated part by sandwiching it between sheets of sheet material and heat sealing.

In the packaging bag of the present invention having the above construction, the resin plate material is integrated by heat sealing between the two sheets constituting the bag, and the hanging hole is formed at that position. There is. Therefore, as compared with the case where the metal eyelets are fixed to the peripheral edge of the hole, damage to the hole due to the weight of the contents can be reduced. The plate material is preferably made of low density polyethylene or ethylene vinyl acetate copolymer.

It is preferable that the packaging bag of the present invention is provided with an extraction port at a position on the lower end side when in the suspended state. With such a packaging bag, the contents can be taken out from the extraction port located on the lower side in the suspended state.

[0010]

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a perspective view showing a packaging bag 10 according to an embodiment of the present invention. The packaging bag 10 is sold in a state of containing a drink such as alcohol, and as shown in FIG. 2, the packaging bag 10 can be hung together with a hook portion 21 provided on a wall surface 20.

The packaging bag 10 has an extraction port 19 at the lower end side in the suspended state. Extractor cap 19
When a is removed, a screw portion (not shown) appears, and the twist cock 30 can be attached thereto. Therefore, the packaging bag
The beverage can be poured into a cup or the like while the 10 is suspended on the wall surface 20. The packaging bag 10 having such a configuration is suitable for commercial use in a tavern or a restaurant. The twist cock may be provided integrally with the bag 10 from the beginning.

FIG. 3 is an enlarged view showing in detail the periphery of the hanging hole 11 of the packaging bag 10. The left and right suspension holes 11 have the same structure, and FIG. 3 shows the left suspension hole 11. In FIG. 3, the hatched area is a heat-sealed area. FIG. 4 shows 4-4 in FIG.
It is a line sectional view.

The packaging bag 10 is constructed by facing two sheet materials 10a and 10b and heat-sealing the periphery thereof. Each sheet material has a layered structure composed of "nylon layer / printing layer / anchor treatment layer / polyethylene layer / linear low-density polyethylene layer". Heat is applied with the linear low-density polyethylene layers facing each other. Sealed. A disc-shaped resin plate member 13 is sandwiched between the two sheet members, and the disc plate 13 is integrated with the sheet members 10a and 10b on both sides by heat sealing. Then, a through hole 11 is formed in the center of the disc plate 13 to serve as a hanging hole.

The hanging hole 11 thus constructed is
The durability is higher than the conventional hanging hole in which metal eyelets are fixed on the periphery of the hole. That is, in the conventional hanging hole in which eyelets are attached, the area of the connecting portion between the ring-shaped eyelet and the hole periphery is small, and when the packaging bag containing a heavy object is suspended for a long time, the eyelet itself is a bag. It can be torn off. On the other hand, in the packaging bag 10 of the present invention, the resin disk plate 13 is provided between the two sheet materials.
Are integrated by heat sealing. Therefore,
The disc plate 13 is firmly integrated with the sheet material on both sides, and even if the disc plate 13 is suspended for a long time, it is almost unlikely that the disc plate itself will be torn off from the bag.

Therefore, the resin disc plate 13
Preferably has a suitable area and thickness depending on the weight of the contents. For example, when the weight of the contents is 10 kg, the disc diameter is about 40 mm, the hanging hole diameter is about 9 mm, and the thickness is about 1 mm. In the illustrated example, the circular disc plate 13 is used, but the plate material sandwiched between the sheets does not have to be circular and may be a square or a triangle as long as it extends with a desired area. ,
Any other shape can be adopted. Such a plate material is preferably made of low density polyethylene or ethylene vinyl acetate copolymer having appropriate flexibility and strength, but in addition to that, a heat seal layer and a heat seal layer on the inner surface in the bag layer constitution are used. A sealable resin can be appropriately used.

As can be seen from FIGS. 3 and 4, the two sheet materials 10a and 10b are spaced apart from the peripheral edge portion 13a of the disk plate 13 heat-sealed between the two sheet materials 10a and 10b. They are heat-sealed directly with each other, and as a result, the heat-sealing portion 15 that extends in a curved shape is formed.
Are formed. The heat seal portion 15 separates the content storage space of the packaging bag 10 from the disc plate 13.

Separating the content storage space from the disc plate 13 in this way has the following advantages. That is, it is possible to avoid the inconvenience that the contents press the plate material 13 when the packaging bags are stacked and transported, and as a result, the sheet material portion corresponding to the peripheral edge portion 13a of the plate material is crushed.

In the embodiment described above, an example in which the present invention is applied to a packaging bag for beverages is shown, but the present invention is
It has a feature in the hanging hole of the packaging bag, and can be applied to any packaging bag that can be hung in a state in which heavy objects are wrapped. The object of packaging is not limited to liquids such as beverages, but may be liquids, semi-liquids, solids, granules, or any other content. As the form of the bag, a gusset bag having folds on both sides is preferable because a large internal volume can be secured.

Further, for example, as shown in FIG. 5, a packaging bag 50 sold in a state in which a hammer 55, which is a heavy object, is housed.
The present invention can be applied to a packaging bag that does not have an extraction port. In the packaging bag 50, a hanging hole 52 is formed in the center of a disc-shaped resin plate 51.
