Benefits of technology

[0013] This pillow can hold and cool the head portion in such a shape as to conform to the shapes of a neck and a head. Therefore, a burden is not cast on a human body. The cooling function of a cold insulator which is incorporated can last long. Moreover, plural kinds of cold insulators to be incorporated can be retained and replaced. An adjustment can be carried out depending on a difference in the physical constitution and uses of a user.

Problems solved by technology

On the other hand, if a shape holding capability is too large, a shape following property is poorer so that the stability of the head and the comfort to sleep are deteriorated.

[0050] While the advantages of the present invention will be apparent from examples, the present invention should not be construed to be restricted based on the description of the examples.

example

[0051] A rubber composition containing a natural rubber as a base material (100 parts by weight of a natural rubber, 115 parts by weight of a filler, 4 parts by weight of a softening agent, 5.5 parts by weight of zinc white, 1.1 parts by weight of stearic acid, 5 parts by weight of a foaming agent, 2 parts by weight of sulfur, 0.9 part by weight of a vulcanization accelerator and 0.6 part by weight of an antioxidant) was put in a metal mold and was vulcanized and foamed at 150° C. for 10 minutes, and was thus molded to manufacture a body comprising a concave portion. On the other hand, a polyurethane film (a thickness of 0.1 mm, a tensile strength of 20N, a tear strength of 8N and an elongation at break of 220%) was laid over a metal mold having such a shape as to correspond to the shape of the concave portion of the body, and the temperature of a polyurethane gel was raised to 50° C. and was poured in an amount of approximately 50 mm into the metal mold, and was filled with a curin...

Abstract

A pillow (1) according to present invention comprises a body (3) including a concave portion (7) in a central part and a cold insulator (5) incorporated in the concave portion (7). The cold insulator (5) has a gel material enclosed in a bag member which is formed by an enclosing film. It is preferable that the body (3) should be formed of a rubber or a synthetic resin material and should have a flexibility and a restoring property for a deformation. It is more preferable that the gel material should be a hydrogel or a lipogel. Furthermore, a plurality of dents (9) is provided on the surfaces of the body (3) and the cold insulator (5). The pillow can hold and cool a head in such a shape as to conform to the shapes of a neck and a head, thereby casting no burden on a human body. A cooling function lasts long by the cold insulator (5) incorporated in the body (3). Plural kinds of cold insulators (5) to be incorporated can be retained and replaced, and can be regulated depending on a user and a situation.

Description

[0001] This application claims priority on Patent Application No. 2003-312629 filed in Japan on Sep. 4, 2003 BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a pillow. More particularly, the present invention relates to a pillow to be used for cooling a head. [0004] 2. Description of the Related Art [0005] Conventionally, a water pillow has been used for cooling a head of a person. The water pillow is troublesome to replace ice or water. For the replacement, a place, a vessel or the like for treating the water is required. In order to eliminate the troubles, various devises have been made. For example, Japanese Laid-Open Patent Publication No. 2002-330986 has described a pillow in which a capsule requiring no water is put. In place of the ice, the capsule is cooled and filled in the pillow for use. [0006] Japanese Laid-Open Patent Publication No. 2001-297 has described a pillow in which a cold insulator is accommodated in a pocket ...
