Multi-sectional clamping type air enclosure

Abstract

A multi-sectional clamping type air enclosure is constituted by connecting a second air cylinder sheet(s), a third air cylinder sheet, a fourth air cylinder sheet(s) sequentially in series to a first air cylinder sheet, in which an air filling passageway is disposed in the first air cylinder sheet to allow air to be filled in a plurality of first air cylinders and the second air cylinder sheet(s), the third air cylinder sheet and the fourth air cylinder sheet(s) communicated therewith to be filled with air and expanded. Thereafter, the second air cylinder(s) and the fourth air cylinder sheet(s) are bended toward the third air cylinder sheet to form approximately a U-typed body, and auxiliary air cylinders of the air cylinder sheet are then bended toward main air cylinders of the air cylinder sheet to cause side air cylinders of the air cylinder sheet to be approximately perpendicular to the main air cylinders of the air cylinder sheet so as to provide an article with the multi-facial cushioning effect and the article is accepted in an outer box with a different size by bending the air cylinder sheets.
