专利汇可以提供Dunnage device专利检索，专利查询，专利分析的服务。并且An inflatable, bladderless dunnage device of economical construction for shoring merchandise in a storage compartment. The member includes a unitary body and valve means connected therewith. The body is formed of a laminate of pressureretaining, flexible material including a layer or sheet of flexible polymeric material and a layer of open mesh textile fabric covering at least substantially the entire outer surface of the polymeric material layer. The polymeric material fills the openings or interstices of the fabric layer to form a bond therewith capable of withstanding at least low to intermediate pressure when the member is inflated. Preferably the polymeric material is at least substantially air impervious and the textile fabric layer is preferably of a leno weave construction.，下面是Dunnage device专利的具体信息内容。

权利要求

2. The member as claimed in claim 1 wherein the fabric layer is of a straight leno weave construction.

2. a cloth layer of open weave textile fabric material disposed in substantially a coplanar relationship with the outer surface of said sheet of polymeric material and covering the entire outer surface of said sheet with the polymeric material filling and extending through the interstices of the cloth layer to form a bond therewith capable of withstanding a pressure of at least 1 psi when said device is inflated to control the expansion of the polymeric material; and B. valve means operably connected with said body for inflating and deflating said device.

3. The member as claimed in claim 1 wherein the fabric layer is of a reverse leno weave construction.

4. The member as claimed in claim 1 wherein said body is formed of opposed plies of said pressure retaining material with at least a portion of the peripheral outer edges thereof sealed to form a pressure-tight seam.

5. The member as claimed in claim 4 wherein said body further includes a strip of flexible material extending substantially around the entire interior periphery of the inflatable member and fitting into the crotch-like contour formed by said body adjacent said sealed outer edges thereof to provide reinforcement therefor with said member thereby capable of withstanding increased pressure during inflation.

6. The member as claimed in claim 1 wherein said layer of flexible polymeric material is composed of at least one substantially fluid-impervious elastomer and said textile fabric layer is composed of at least one material selected from the group consisting of cotton, nylon, rayon or polyester.

7. The member as claimed in claim 6 wherein the flexible polymeric material is a butyl elastomer and the textile fabric material is nylon.

8. An inflatable dunnage device for shoring merchandise in a storage compartment, said device comprising: A. an inflatable body of unitary construction formed of opposed laminated plies of pressure-retaining flexible material with at least a portion of the peripheral outer edges thereof sealed to form a pressure-tight seam, each said ply including:

9. The device as claimed in claim 8 wherein the cloth layer is of a straight leno weave construction.

10. The device as claimed in claim 8 wherein the cloth layer is of a reverse leno weave construction.

11. The device as claimed in claim 8 wherein said seam is formed around the entire peripheral outer edges thereof and a generally V-shaped strip of flexible fabric material extends substantially around the entire interior periphery of the inflatable device fitting into the crotch-like contour formed by said body adjacent said sealed outer edges thereof to provide reinforcement therefor with said device thereby capable of withstanding pressures of up to about 4 psi during inflation.

12. The device as claimed in Claim 8 wherein said flexible polymeric material is at least one elastomer selected from the group consisting of butyl, neoprene and acrylonitrile rubber and said textile fabric material is at least one material selected from the group consisting of cotton, nylon, rayon or polyester.

13. The device as claimed in Claim 12 wherein said flexible polymeric material is a butyl elastomer and said textile fabric material is nylon.
