Description

  The present invention relates to a cold insulator, and more particularly, to a cold insulator that can be suitably used for cooling various parts of a human body by using a cooling action of a refrigerant body including gel.

Conventionally, a cooling medium containing gel is housed in a pillow-size, sheet-size, or other exterior body to form a cooler, and this head is covered with this cooler when sleeping at high temperatures such as in summer. Cooling or placing on a bed to cool the back of the body or the like is performed.
In the case of such a cooling device, for example, when used as a substitute for a comforter, in addition to obtaining a cooling effect, it is required to obtain a good feeling of use that is lightweight and flexible. .

  Further, in the case of such a cooling tool, since the fluidity of the refrigerant retaining body including the gel housed therein is large, the refrigerant retaining body is unevenly distributed in the exterior body due to the weight of the body simply by housing the refrigerant retaining body in the exterior body. As a result, the cooling effect on the body cannot be sufficiently expected.

  The applicant of the present application previously described, as shown in Patent Document 1, as a cold insulator having a good cooling effect on the body at bedtime or the like, two sheets of rectangular sheet-shaped covering materials are overlapped with each other, and the lining is overlapped. An outer periphery formed by a flat shape with an outer periphery welded portion by high-frequency heating between each other, an annular inner region, and a plurality of partial welded portions having heat release holes and a linear intermediate weld portion, and an outer periphery Proposed a cold insulation tool having a structure including a welded portion, a refrigerant body containing gel stored in a state in which the flow is regulated in the exterior body by the partial welded portion and the intermediate welded portion of the inner region, and has received a utility model registration .

Registered Utility Model No. 3146465

  The problem to be solved by the present invention is that the internal flow of the refrigerant retaining body can be prevented and the cooling action of the object such as the body can be surely exerted, and it is light in weight, and a better feeling of use can be obtained. This is a point that there is no cold insulator that also excels in the property.

  The cold insulator according to the present invention is formed by stacking two sheet-like covering materials having a surface material made of a cloth-like material and a lining material made of a non-water-absorbing material that can be welded by heating. An outer body formed of a mat-like form by forming an outer periphery welded portion and a non-reservoir body non-accommodating portion defined by a plurality of partial weld portions between the linings in the inner region, and the outer periphery welded portion in the outer region, the inner region A refrigerant-retaining body including a gel built in a refrigerant-retaining body region continuously formed in a region other than the refrigerant-retaining body non-accommodating portion defined by the partially welded portion, and an outer periphery sealing portion by sewing provided on the outer periphery of the exterior body The most important feature is to have

  According to the first to third aspects of the invention, since the refrigerant-retaining body non-accommodating portion that does not accommodate the refrigerant-retaining body is arranged in the inner region of the exterior body, the storage amount of the refrigerant-retaining body can be reduced. Accordingly, the cold insulator itself can be reduced in weight while suppressing the flow of the refrigerant holder by the refrigerant insulator non-accommodating portion, and when used as a bedding, a good feeling of use can be obtained, and the portion of the refrigerant refrigerant non-accommodating portion can be obtained. By folding the battery pack, it is possible to realize and provide a cold insulator that can reduce the occupied space and can be conveniently stored and stored.

  According to invention of Claims 4-6, while having the same effect as the invention of Claims 1-3, the structure which provided the some heat radiating hole in each refrigerant | coolant maintenance body non-accommodating part was added. Therefore, the heat radiating effect of the heat acting on the cold insulator is also good, and a cold insulator capable of obtaining a good feeling when used as a bedding can be realized and provided.

  According to the invention described in claims 7 to 9, the same effect as in the case of the invention described in claims 1 to 3 can be obtained, and the elastic material is housed in each refrigerant retentive body non-accommodating portion, so that the elasticity is further increased. When it becomes large and used as a bedding, it is possible to realize and provide a cold insulator capable of obtaining a better feeling of use.

Hereinafter, the cold insulator which concerns on Examples 1-3 of this invention is demonstrated.
Example 1
A cold insulator 1 according to Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 4.

  As shown in FIGS. 1, 3, and 4, the cold insulator 1 according to the first embodiment is made of a cloth material such as cotton, polyester, rayon, hemp, brushed fabric, chirimen, cocoon willow, and towel cloth. 3 and one covering material obtained by polymerizing a lining 4 made of a non-water supply material such as polyvinyl chloride (PVC) that can be welded by high-frequency heating, and the other covering made of the outer lining 3 and the lining 4 having the same configuration The material is overlapped in an arrangement in which the linings 4 face each other, and the outer periphery welded portion 5 between the linings in the outer peripheral region subjected to high-frequency heating processing and a plurality of rectangular shapes between the linings in the inner region are provided and spaced apart A plurality of rectangular shapes defined by a plurality of partially welded portions 6 by high-frequency heating processing, for example, five rows of parallel-arranged refrigerant-reservoir non-accommodating portions 7 are formed to form a rectangular mat-like shape in plan view. Exterior body 2 and said exterior 2 includes gels that are continuously formed in a region other than each of the retentive medium non-accommodating portions 7 defined by the peripheral weld portion 5 in the inner region and the partial weld portion 6 in the inner region. A refrigerant-retaining body 8 and a rectangular outer periphery sealing portion 9 by sewing (hem winding) using a side ground so as to wrap the outer edge portion of the outer periphery welding portion 5 over the entire outer periphery of the exterior body 2. ing.

  As a composition of the refrigerant | coolant maintenance body 8 containing the said gel, the composition which consists of gel, sodium polyacrylate, ammonium sulfate, sodium sulfate, glycerin, water, a fungicide, etc. can be mentioned, for example. In the present invention, the composition of the refrigerant retaining body 8 is not limited to the above example.

  In the first embodiment, the outer peripheral region and the inner region of the exterior body 2 are defined and described as shown in FIG.

  Further, the overall size of the exterior body 2 in Example 1 is a pillow cover size, and is set to, for example, 30 cm long × 40 cm wide as shown in FIG. In the present invention, the overall size of the outer package 2 is not limited to the above example.

  As shown in an enlarged view in FIG. 4, the width size of the partial welded portion 6 itself is set to a small width of 0.4 cm, and the size of one refrigerant retaining member non-accommodating portion 7 defined by the partial welded portion 6 is For example, the length is set to 20 to 22 cm and the width is 3 cm. In FIG. 4, reference numeral 10 denotes a seam that forms the outer peripheral sealing portion 9.

  According to the cold insulator 1 according to the first embodiment, since the cold insulators non-accommodating portions 7 arranged in parallel in five rows are arranged in the inner region of the exterior body 2 constituting the cold insulator 1, The storage amount of the refrigerant insulating body 8 including the gel as the entire cold insulator 1 is reduced as compared with the cold insulator of the same size previously proposed by the applicant of the present application, for example.
