DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a cooling / heat storage unit of the present invention, FIG. 2 is a front view of a bottle equipped with a cooling / heat storage unit, FIG. 3 is a cross-sectional view of FIG. FIG. 4 is an enlarged explanatory view of a main part of FIG. 3.

The cooling and heat storage units are roughly divided into
It comprises a heat storage belt 2 and a cool / heat storage box 3.

The cooling / heat storage belt 2 is a belt-like material. In this example, the belt 2 has two layers, a nonwoven fabric 2c as a base material, and an aluminum evaporation layer 2d as a heat reflection layer on the outer surface. In this example, a female fastener 2a is laminated on the inner surface of the cold storage / heat storage belt 2 as a holding unit that holds the cold storage / heat storage box along the length direction. A number of cuts 2b are cut into strips at both ends in the width direction of the cool / heat storage belt 2.

In the cold storage / heat storage box 3, a cold storage agent or a heat storage agent B is sealed in a straight cylindrical translucent plastic box.

Known cold insulators can be used. For example, an aqueous solution containing potassium chloride and sodium chloride at a high concentration or an antifreeze such as ethylene glycol or polyethylene glycol mixed with these can be used.
It is liquid at normal temperature, can be arbitrarily manufactured at a freezing point of -5 ° C, 10 ° C, or the like, and a commercially available product can be used.

As the heat storage agent, polyethylene glycol, waxes or the like having a high molecular weight can be used. The heat storage agent is solid at normal temperature, and the melting point can be arbitrarily manufactured at 60 ° C., 70 ° C., 90 ° C. depending on the use. Can be used.

The shape of the cold storage / heat storage box 3 is substantially a straight cylinder, but a preferred example is one having a concave surface on one side and a convex surface on the other surface so as to be easily applied to, for example, a cylindrical bottle. It is. At both ends in the longitudinal direction of the cold storage / heat storage box 3, male fasteners 3a that can be engaged with the female fasteners 2a of the cold storage belt are attached.

As described above, the cooling / heat storage belt 2 and the cooling / heating
Although the heat storage box 3 is a separate body, it can be fixed at any position as shown in FIG.

FIGS. 2 to 4 show a state in which a cooling / heat storage unit is attached to a beverage bottle. In this example, twelve cold storage / heat storage boxes 3 are attached to the cold storage / heat storage belt 2,
A female fastener 2a attached to the inner surface of the cold storage / heat storage belt 2 and a male fastener 2e attached to the outer surface are overlapped and fixed.

Next, a method of using the cool storage / heat storage unit of the present invention will be described. First, the cold storage / heat storage box 3 is put into a freezer to freeze the cold storage agent or the heat storage agent therein, and these are arranged side by side as shown in FIG. The number and position of the cold storage / heat storage boxes 3 must be PE
It is determined according to the size of the T bottle. On the other hand, a PET bottle containing a beverage to be kept cool or warm is taken out of a refrigerator or a storage cabinet, and a cool / heat storage unit is wound around the body of the PET bottle as shown in FIG. 2, and the end of the belt is fixed with a hook-and-loop fastener. By winding like this,
The cold storage / heat storage box 3 comes into close contact with the body of the PET bottle. Further, since the felt of the cold storage / heat storage belt 2 functions as a heat insulating material and the metal coat 2d is provided on the outside, the outside air temperature is almost shut off. In addition, since there are cuts 2b at both ends of the belt, this portion can be bent inward, and a gap corresponding to the thickness portion of the cool storage / heat storage box 3 can be closed.

In the above example, the means for fixing the cool / heat storage box 3 and the cool / heat storage belt 2 and the means for fixing the end of the winding of the cool / heat storage belt 2 are indicated by hook-and-loop fasteners.
It is also possible to use magnetic fixing such as a magnetic tape or the like, or a concave and convex hook or button. The cold storage / heat storage belt 2 is shown as a metal-laminated nonwoven fabric. However, the metal lamination is not essential.
Insulating materials such as thick woven fabric and knitted fabric can be used. Further, the method for providing the engaging portion such as the male fastener 3a in the cool / heat storage box 3 is not particularly limited. For example, the method may be applied with an adhesive or a groove may be formed in the cool / heat storage box 3 in advance. A hook-and-loop fastener or the like may be fitted into the groove.

The example shown in the drawing is an example in which a beverage PET bottle is kept cool. In addition, bottles and cans can be kept cold and / or warm in the same manner. Also, when cooling in the cooler box,
It can be used efficiently by covering a cooler unit containing a cooler so as to cover the upper surface of the cooler packed in the cooler box, and covering the cooler unit with a lid from above. Also,
In the case where heat is kept in the cooler box, the heat storage unit containing the heat storage agent can be efficiently used by laying a heat storage unit containing the heat storage agent at the bottom of the object to be cooled packed in the cooler box.

On the other hand, when cooling or warming an affected part of an emergency or a tired muscle, a cooling or heat storage agent is selected so as not to be too cold or too warm, and a cooling or heat storage box is directly provided via a towel or the like. Should be used so as not to come into contact with the affected area.

Since the cool / heat storage unit of the present invention is used by covering the cool / heat storage box 3 with the heat-insulating cool / heat storage belt 2, the cool / heat storage maintenance time is extremely long as compared with the conventional use method. When the cool / heat storage agent is warmed and the cool / heat storage effect is lost, only the cool / heat storage box can be removed and freezing / heating can be performed again. The conventional wound-type cold storage / heat storage device is, for example, a device in which a cooling / heat storage agent is filled in a sheet-like bag in which a cooling / heat storage agent is divided into a number of rooms, but in this case, the whole is frozen or heated. The bag portion as a container became brittle during repeated use, and was inferior in durability. However, the cool / heat storage unit of the present invention does not need to freeze or heat the cool / heat storage belt 2 and freezes or heats only the cool / heat storage box 3, so that it can be used semipermanently.

FIG. 5 is a view of another cold storage / heat storage body of the present invention, wherein A is a plan view, B is a side view, and C is a front view. Numeral 4 denotes a cold storage / heat storage body, in which a bag made of a plastic sheet contains a cold storage / heat storage agent.

FIG. 6 is a view of another cooling / heating belt according to the present invention, wherein A is a plan view and B is a front view. In this example,
A number of pockets 5 in the form of two bags of cold storage / heat storage belts are formed,
The bag-shaped cold storage / heat storage body 4 shown in FIG. 5 can be stored therein. Cotton fasteners 6 are attached to both sides of the both ends of the cool / heat storage belt 2.

FIG. 7 is a perspective view of a bottle equipped with a cool / heat storage unit of the present invention. A cool / heat storage belt 2 containing a cool / heat storage body 4 in a pocket 5 is wound around a bottle 1. They are stored in the heat insulation bag 7. In the case of this example, since the adhesion between the bottle and the cold storage / heat storage body is good, a more efficient cold storage / heat storage effect can be obtained.

Hereinafter, the effects of the present invention will be described in detail with reference to examples.

[0030]
