Next, with reference to the attached drawings, a gentle cooling apparatus according to an embodiment of the present invention will be described.
The gentle cooling apparatus 10 according to the first embodiment of the present invention is made using a heat-insulating sheet material 11 whose surface is covered with a cloth, and an opening 12 that can be opened and closed is formed in part. The flat bag body 13 and the first and second cold insulators 16 and 17 housed in the intermediate bag 15 are provided as cold insulating materials that can be taken in and out of the flat bag body 13 through the opening 12. These will be described in detail below.

The sheet material 11 is made of a foamable rubber sheet 18 having a thickness of 1 to 7 mm (more preferably 2.5 to 5 mm) and a chemical fiber having a strength integrally bonded (coated) thereon (for example, , Nylon, tetron, vinylon, etc.). The sheet material 11 may be a fabric used for diving clothes.
The flat bag 13 is cut into a rectangular shape with corners arced as shown in FIG. 1A, and the periphery is joined with a sufficiently strong thread (made of chemical fiber). .

This state will be described in detail. As shown in FIGS. 1 (B) and 2 (A), the front and back sheet materials 11 face each other at the cut end faces 22 and 23, and the cut end faces are formed. After joining 22 and 23 using an adhesive, they are sutured. In some cases, as shown in FIG. 2 (B), after the back surface (inner surface) of the foam rubber sheet 18 at the ends of the front and back sheet materials 11 are brought into contact with each other and bonded using an adhesive. Further, it may be sutured. In the production of the flat bag body 13, both the joining method shown in FIG. 2 (A) and the joining method shown in FIG. 2 (B) may be used for joining the sides. If it is only a part of the sides, the sheet material 11 may be simply bent.

The rectangular flat bag 13 has, for example, a vertical (= height h, short side) range of 30 to 45 cm and a horizontal W (long side) range of 30 to 70 cm. A seam (an example of a sewing means) 24 penetrating through the flat bag 13 is formed, and the inside of the flat bag 13 is divided into left and right at the center. The seam 24 is provided at the center of the flat bag body 13, but its length L is about 1/4 to 1/2 of the height h of the flat bag body 13.

As shown in FIG. 1C, a long opening 12 is provided on the left and right of the back of the flat bag body 13, and a fastener (usually referred to as “zipper” or “chuck”) (not shown) is provided in the opening 12. It is provided and can be opened and closed. The width P of the opening 12 is 0.85 to 0.95 times the height h of the flat bag body 13. Here, a planar fastener, a button, or the like may be used instead of the above-described “zipper”.

The intermediate bag 15 for storing the first and second cold insulators 16 and 17 is made of a synthetic resin bag and has sufficient heat insulating properties and cold insulating properties. The intermediate bag 15 may be made of cloth.
After the intermediate bag 15 and the first and second cold insulators 16 and 17 are stored, the periphery of the intermediate bag 15 may be sealed with a heat seal or the like, but a part of the periphery may be opened.

Inside the flat bag body 13 divided into two by the seam 24, a first cold insulator 16 and a second cold insulator 17 are arranged in a state of being accommodated in the intermediate bag 15, respectively. The first cooler 16 contains a first sealed container 26 made of synthetic resin and an antifreeze and antifreeze gel 27 housed in the first sealed container 26, which is antifreeze at the temperature of a freezer of a household refrigerator. Has been. That is, since the freezing point of the antifreeze gel 27 is set to a temperature lower than -21 ° C., it is not easily solidified (preferably, frozen at a temperature lower than −21 ° C. and higher than −30 ° C.).

The second cooler 17 includes a second sealed container 28 made of synthetic resin, and a freezing gel 29 that freezes at the temperature of the freezer of the household refrigerator housed in the second sealed container 28. ing. And since the freezing point (melting | fusing point) of this freezing gel 29 is made into -15 degreeC or more (preferably -12--14 degreeC), it solidifies easily when it cools with the freezer of a household refrigerator.

In general, the temperature of a freezer in a home refrigerator is about -18 ° C on average, and when stored in the freezer for a long time, the gel in the second cooler 16 does not freeze (thus referred to as an antifreeze gel). The gel in the cold insulator 17 is frozen (hence, called a freezing gel). And each has a big heat of fusion and has a bigger heat absorption power. In addition, since the 2nd cold insulator 17 freezes, a bigger heat of fusion is required and the heat absorptivity is larger than the 1st cold insulator 16.

When the second cold insulator 17 is frozen, it becomes a rectangular shape in plan view and hardly deforms. Therefore, the second cold insulator 17 is put in the flat bag body 13 while being stored in the intermediate bag 15. The opening 12 has an opening size sufficient for the second cooler 17 to enter.
The first and second cold insulators 16 and 17 are preferably commercially available, and the average thickness of each is about 1 to 2.5 cm.

When using this gentle cooling device 10, the 1st, 2nd cold storage tools 16 and 17 are put into the freezer of a household refrigerator, and are cooled. As a result, the first cooler 16 is not frozen, but the second cooler 17 is frozen. The first and second cold insulators 16 and 17 may be stored in the freezer after being put in the intermediate bag 15. In addition, since it will maintain the shape as it is about the 2nd cooler 17, if it freezes, it will be made flat and cooled.

When using the mild cooler 10, take out the first and second coolers 16 and 17 from the freezer in the intermediate bag 15, or remove the first and second coolers 16 and 17 from the freezer. Take it out and put it in the intermediate bag 15 and put it into the flat bag 13 through the opening 12.
When used as a pet cold insulation mat (an example of a pet cold insulation tool), in use, the second cold insulation device 17 is in the lower position and the first cold insulation device 16 is in the upper position. Put in. Thereby, the cushioning property of the first cold insulator 16 containing the antifreeze gel can be utilized.
