FIG. 1 is an overall perspective view of the cooling sensation mat 1 of the present invention, and FIG. 2 is an enlarged sectional view thereof. The cooling mat 1 of the present embodiment includes an upper surface material 2, a lower surface material 3, and an intermediate material 4 disposed between the upper surface material 2 and the lower surface material 3, and the intermediate material 4 includes water, It consists of a mixture containing powders of sodium sulfate, sodium chloride and kaolin.

  Such a cooling sensation mat 1 of the present invention can be manufactured at low cost. Moreover, the cooling mat 1 of the present invention can effectively absorb the heat of the heating element without cooling in a refrigerator or using ice. Moreover, since the intermediate material 4 contains the kaolin powder, it is suppressed from becoming large and solidified in the crystalline state, and it becomes possible to eliminate the uneasiness that is crazed during use.

  In the cooling sensation mat 1 of the present embodiment, the upper surface material 2 and the lower surface material 3 both have a two-layer structure. The upper surface member 2 includes an outer layer sheet 5 made of polyester disposed on the outer side and an inner layer sheet 6 made of vinyl chloride disposed on the inner side. The lower surface material 3 includes an outer layer sheet 7 made of polyester disposed on the outer side and an inner layer sheet 8 made of vinyl chloride disposed on the inner side. The outer layer sheet 5 and the inner layer sheet 6 constituting the upper surface material 2 and the outer layer sheet 7 and the inner layer sheet 8 constituting the lower surface material 3 are bonded to each other via a hot melt welding agent. Further, the periphery of the upper surface material 2 and the lower surface material 3 is subjected to a lock process.

  Between the upper surface material 2 and the lower surface material 3, a bag shape is formed, and an intermediate material 4 made of a mixture of water, sodium sulfate, sodium chloride and kaolin powder is enclosed therein.

  Sodium sulfate is usually used as a desiccant and is known as a highly safe substance for the human body. Further, when heated, sodium sulfate hydrate dissolves in crystal water at about 32 ° C. and melts, and becomes anhydrous at 100 ° C. Further, when melting, it absorbs ambient heat and lowers the temperature, so that a high effect as a cryogen can be obtained.

  In the present invention, sodium sulfate hydrate is encapsulated as a part of the intermediate material 4, and the cooling sensation mat 1 using the intermediate material 4 is brought into contact with the body, so that the sodium sulfate hydrate is converted into crystal water by body temperature. Melt and melt. Thereby, the cooling sensation mat 1 efficiently absorbs heat generated from the body, and the user can obtain a comfortable cooling sensation.

  Moreover, the said sodium chloride can use what is generally consumed industrially suitably. Then, by mixing sodium chloride with the intermediate material 4, it is possible to eliminate the stuffy discomfort immediately after use without causing the crystalline intermediate material 4 to increase in size.

  The kaolin powder is dispersed and arranged as a part of the intermediate material 4. Kaolin is an ore formed by weathering feldspar and mica, and is hydrous aluminum silicate. The particles are extremely small, the surface area is large, and the adsorption power is excellent. As shown in FIG. 3, when the body is placed on the upper surface material 2 of the cooling sensation mat 1, a temperature gradient is generated, the upper surface material 2 side is in the high temperature region a, and the lower surface material 3 side is in the low temperature region b. become. However, the kaolin powder having a high thermal conductivity is distributed and arranged in the intermediate material 4, so that these temperature differences are alleviated and the internal temperature is made uniform. In particular, when the temperature difference is large inside the intermediate material 3, the solidification and agglomeration of the intermediate material 4 are likely to proceed in the high temperature region a on the upper surface material 2 side, but the solidification is delayed by adding kaolin powder. , And can prevent a stuffy sense of incongruity.

  In order to effectively exhibit such an effect, the blending amount of the kaolin powder is desirably 0.5 to 5% of the intermediate material 4 in mass%. The particle size of kaolin is set as appropriate and is not particularly limited.

  Moreover, as shown in the drawing, the upper surface material 2 and the lower surface material 3 are heat-welded by high frequency processing. The high frequency processing is a welding processing in which a part of the object to be welded is dissolved and bonded by applying high frequency energy to the heat-fusible material. By using high-frequency processing, a heat-welded portion 9 is formed at a location where the upper surface material 2 and the lower surface material 3 are heat-welded.

  It is preferable to form the heat welding part 9 around the upper surface material 2 and the lower surface material 3 and at a plurality of locations in the mat longitudinal direction. As shown in the drawing, by forming the heat welding portions 9 in a parallel state at a plurality of locations in the mat longitudinal direction, the middle material 4 is not biased during use. Further, the formation of the heat-welded portion 9 enables the cooling sensation mat 1 to be folded in three as shown in FIG. 4 or in six as shown in FIG.
