<P>PROBLEM TO BE SOLVED: To solve problems wherein a user cannot find a desirable pillow surface at a desirable position in a desirable direction for stretching the neck with a regular sleeping pillow even if the user tries to extract the resistance effective for stretching by pressing, hooking or rubbing the head on the pillow surface, wherein the user can not rest the head at a desirable angle or at a desirable position because the user can not freely make motions while the user lies on a side and because the height of the pillow is too low, and wherein the user can not desirably stretch the neck because the head slides on the pillow when the head is applied to the pillow and appropriate force can not be applied to the head, and wherein an appropriate pillow can not be found in the search in the market or in patent information. <P>SOLUTION: Samples of pillows in various shapes and made of various materials are developed in search of the pillow capable of being easily applied to a selective region in the face or head of the user and capable of extracting the sufficiently necessary drag. As a result of the research and development, it is found that the pentangular column-shaped pillow made of an elastic material such as foamed plastics known as a cushion material can totally solve the above problems, and the practicality and the safety of the pillow are proved and confirmed after the long-time use. <P>COPYRIGHT: (C)2010,JPO&INPIT |
