Claims (1)

[Claims for Utility Model Registration] 1. An adsorption buffer made of a flexible material consisting of an open chamber with a periphery that can be adsorbed as a flat annular surface on the surface of the target article, and a closed air chamber that traps air. A large number of air cells are formed on the surface of the sheet, and when the peripheral edge is pressed against the surface of the target article, the open chamber becomes a decompression chamber and the peripheral edge becomes a flat annular surface and is adsorbed to the surface of the target article, and the closed air chamber is formed as a flat annular surface. A highly absorbent buffer sheet that forms a virtually incompressible buffer between the decompression chamber and the base sheet. 2. The peripheral edge of the open chamber is folded back at the outer end to form a substantially truncated cone-shaped side wall and is bonded to the base sheet, and the partition wall forming the bottom wall of the open chamber, the side wall, and the base sheet The highly absorbent and cushioning sheet according to claim 1, which is a registered utility model, and has a closed air cell chamber formed therein. 3. The peripheral edge of the open chamber is continuous with a substantially truncated conical side wall with a small opening, and the lower end of the side wall is folded inward to form a hemispherical partition wall, and the partition wall and the base sheet are connected to each other. The highly absorbent and cushioning sheet according to claim 1, wherein the sealed air cell chamber is formed between them. 4. The suction buffer and the base sheet are made of different materials, and the suction buffer is arranged on the base sheet at intervals not significantly larger than the outer diameter of the periphery. Highly absorbent and cushioning sheet as described. 5. The high suction buffer sheet according to claim 1 or 4, wherein the suction buffer is formed on one surface of a base sheet. 6. The adsorption buffer is formed on both surfaces of the base sheet.
The high adsorption buffer sheet according to item 1 or 4. 7 Utility model registration claim 1, in which the adsorption buffer is formed on one surface of a base sheet, and the other surface of the base sheet is affixed to the surface of another cushioning material.
High adsorption buffer sheet as described in section.
