Pillow

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.

1 . A pillow comprising: 
 a body including a concave portion in a central part; and    a cold insulator incorporated in the concave portion, the cold insulator having a gel material enclosed in a bag member.    
   
   
       2 . The pillow according to  claim 1 , wherein the body is formed of a rubber or a synthetic resin material and has a flexibility and a restoring property for a deformation.  
   
   
       3 . The pillow according to  claim 1 , wherein the gel material is a hydrogel or a lipogel.  
   
   
       4 . The pillow according to  claim 1 , wherein a plurality of dents is provided on surfaces of the body and the cold insulator.
