Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a refrigerant bag,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a refrigerant bag and a manufacturing method thereof, and more particularly, to a new refrigerant bag without a sewing line and a manufacturing method thereof.

Methods of lowering the temperature by placing an ice pack in a plastic-made ice box are known. These items are bulky and take up a lot of space when not in use.

As a result, a refrigerant bag was developed that allows ice packs to be placed in bags made of cloth, which can be folded after unloading the ice pack. U.S. Patent No. 5,533,361 discloses a refrigerant bag in which a double-sided side is formed in a rectangular open-topped bag to form a pocket and an ice pack is inserted therein.

Such a refrigerant bag has a problem that when the ice pack is removed from the bag, it is often lost during storage, and a method of folding the refrigerator without removing the ice pack from the bag has been developed. Korean Patent Laid-Open No. 10-2012-0017434 discloses a foldable bag in the form of a rectangular open top. This bag has a rectangular shaped ice pack on the side, and it is folded between the ice pack and the ice pack so that it can be folded without removing the ice pack from the bag.

This method is advantageous in that the bag can be folded without removing the ice pack, but it is necessary to perform the stepping to separate the boundaries between the ice pack and the ice pack so that the bag is folded into a predetermined shape. In this case, the stranded wire is exposed to the outside of the bag, which is disadvantageous in terms of design.

Also, there is a problem in that the cold pack of the ice pack flows out through the fine holes drilled by the stranded wire, the cold power is low, and the ice pack is not insulated between the ice pack and the bag.

A problem to be solved by the present invention is to provide a method for manufacturing a folding bag in which an ice pack is embedded without the outer skin and the inner skin of the bag being stuck.

Another problem to be solved by the present invention is to provide a new bag having a high heat insulation property between the outer skin of the bag or the inner pack and the ice pack.

In order to solve the above-mentioned problems, the refrigerant bag according to the present invention comprises at least a part

Bag shell layer; A first quick-setting layer on the inner side of the shell; A second fast free layer located inside the first quick free layer; And a bag inner skin layer on the inner side of the second quick release layer, wherein the first quick release layer and the second release material layer are partitioned into a thin film for inserting the ice pack, And a wall surface in which ice packs are present in at least a part of the spaces between the fastening layers.

In the present invention, the outer skin layer, the first quick-release layer, the second quick-release layer, and the endothelial layer are folded together along the portion partitioned by the tape, and the bag is folded.

In the present invention, it is preferable that a heat insulating layer is further interposed between the first quick-setting layer and the second fastening layer so that the cold air of the ice pack can be prevented from escaping to the outside of the bag.

In a preferred embodiment of the present invention, the bag outer shell layer; A first quick-setting layer on the inner side of the shell; A heat insulating layer on the inner side of the first quick-cushion layer; A second accelerating layer inside the heat insulating layer; And a bag inner skin layer on the inner side of the second quick release layer, wherein the first quick release layer, the heat insulation layer and the second quick release layer are partitioned into a strand for insertion of the ice pack, The bag is folded along the portion where the bag skin layer and the first fast-crotch layer, the heat insulating layer, the second fast-crotch layer, and the endothelial layer are stitched together with the tape, and the bag is folded along the area partitioned by the fasteners.

In the practice of the present invention, the outer layer may be formed of a spun fabric, for example, a spun polyurethane fabric may be used.

In the present invention, it is preferable to use a waterproof fabric or sheet that can prevent the bag from being wetted by the water formed in the ice pack, and the first bag is made of a soft material PVC sheet can be used, and the second speed can use PU treated fabric.

In the present invention, the heat insulating layer is located outside the ice pack so that the cold air of the ice pack does not flow out of the bag, and a foamed resin, for example, a foamed PE sponge, may be used.

In the present invention, the ice pack may be a conventional gel-type ice pack contained in a vinyl package, and preferably has a rectangular shape.

The refrigerant bag according to the present invention can be folded in a state in which the ice pack is built in. However, the outer surface of the bag does not have a partition line due to the stapling, so that it is advantageous from the viewpoint of design and has high durability.

In addition, water droplets formed on the surface of the ice pack can prevent wetting of the bag, and it is possible to prevent the cold pack of the ice pack from flowing out in the presence of the heat insulating layer, thereby increasing the refrigerating duration time.

An arm buckle 131 is attached to the lid 120 so that the body 110 (Not shown). On both sides 113 of the body 110, there is a shoulder strap 140 that can be attached to the shoulder.

The bottom surface 111 and the front and rear surfaces 112 of the body 110 form a cooling surface 200 in which an ice pack is inserted between the inner skin and the outer skin and are integrally formed without being divided into separate pieces.

2 and 3, the bag body 210, the first core 220, the heat insulating layer 230, the second core 240, and the bag inner layer 210 are formed on the rim of the cooling surface 200 of the present invention. There is only an outer perforated line 270 on the rim of the bag 250 and no outer perforations are formed on the outer surface of the bag. The inner pincushion line 280 becomes invisible from the outside.

3, the cooling surface 200 of the present invention includes a bag envelope 210, a first core 220, a heat insulation layer 230, a second core 240, and a bag inner skin 250 Loses. The first core 220, the insulation layer 230 and the second core 240 are spaced apart from each other by an internal puncture line 280 formed by a stitch that penetrates from the first core 220 to the second core 240, And an ice pack 260 is inserted between the heat insulation layer 230 and the second core 240. The ice pack 260 can be inserted only in some compartments depending on the shape of the bag folded.

As shown in Fig. 4, first, the casing is cut to manufacture the refrigerant bag 100. As shown in Fig. The fabric is cut to size according to the size using 600D PVC, and the fabric is cut into a total of 7 pieces. Two sheets of large rectangular fabric form the cooling surface.

As shown in FIG. 5, the endothelium of the 210D fabric is also cut and cut into a total of 7 pieces having the same shape as the outer surface of the bag.

6 and 7, the first core 220 is made of a PVC sheet, the insulation layer 230 is made of a PE sponge, the second core 240 is made of a 210 DPU fabric, . The cut fabrics of the same size as the cooling surface were overlapped (superimposed so as not to overlap each other for illustrative purposes in the figure), and were stitched side by side so as to be parallel to short sides at predetermined intervals.

As shown in FIG. 8, when the bag skin 210 and the bag inner skin 250 are packed together with the first core 220, the heat insulating layer 230 and the second core 240, Except for the insertion position, the ice pack is inserted and then the thin ice plate is manufactured to manufacture the cooling plate 200.

The cooling plate 200 forms the front and rear surfaces of the bottom surface of the bag, and the side and the lid separately cut are cut and adhered to complete the refrigerant bag.
