Embodiment Construction

[0037] Detailed Description of Preferred Embodiments

[0038] The following detailed description is intended only to illustrate the preferred embodiments of the invention and not to limit the scope of the invention, which is defined by the claims.

[0039] First refer to Figure 1A , the porous gasket material of the present invention comprises a sheet 50 formed of at least two plastic layers. The plastic layers are welded to one another on the two longitudinal sides 11 and 12 . They are also welded to each other in a diagonal manner across their width, thereby forming a plurality of diagonal sleeves 10 . The oblique sleeve 10 terminates downwards before touching the side edge 11 , thereby forming a longitudinally extending inlet channel 14 . Practically all sides of each bushing 10 are sealed except for the side of the bushing facing the inlet channel 14 which has a small opening 22 to allow air to flow from the inlet channel into the respective bushing. In a preferred em...

Abstract

Cellular cushioning material and a method for its production is described. In one scenario, the method includes providing a pre-welded sheet to a user comprised of at least two layers of plastic pre-welded to have a plurality of diagonally oriented, inflatable sleeves extending substantially the entire width of said sheet, and a longitudinally extending air entry passage. Each of the inflatable sleeves has an opening for allowing entry of air from said air entry passage into said sleeve. The user inflates the cellular cushioning material on an as-needed, real-time basis.

Description

field of invention [0001] The present invention relates to the field of porous gasket materials. In particular, the present invention relates to porous gasket materials and methods of producing such porous gasket materials in real time on demand. Background of the invention [0002] Packaging materials are used in many different industries to ensure the safe storage and transportation of various goods. However, since the packaging material doubles as an insulator and shock absorber, it is often extremely bulky, expensive to store and transport, and cumbersome to use. A porous liner, which is a packaging material with an air-filled bladder, has been marketed and sold, with a bladder that inflates and closes when the occasion arises. Although the porous liner provides a high degree of shock absorption and protection, it presents inconveniences to both the manufacturer and the user due to its bulkiness and transportation and storage problems. Porous gasket materials that hav...
