Abstract: By providing a multi-layered, self-sealing, adhesive system constructed for being laminated directly to a thermoplastic or elastomeric elongated tube, a highly effective, easily employed, closure system for securely sealing the elongated slit of elongated, thermoplastic or elastomeric tubes is obtained. In the preferred embodiment, the multi-layered, self-adhering, sealing system of this invention is manufactured in a substantially continuous elongated strip and incorporates a laminating film layer and a film support layer. In this way, secure, integral bonded affixation of the sealing system to the elongated tube is attained in a unique cost-effective, highly efficient manufacturing process. In addition, by integrally affixing the laminating film layer and the film support layer along both sides of the elongated slit of the tube, an adhesive engaging surface is provided for assuring secure, leak-free sealed closure of the elongated tube.

Abstract: By providing a pre-formed compressible substrate with an intimately bonded thin film layer integrally affixed thereto in surrounding protecting relationship, a surface coated cushioning member for mounting to otherwise hard-surfaced products is realized. In the preferred embodiment, the surface coated cushioning member of the present invention is formed from foamed thermoplastic, elastomeric or rubber polymers or copolymers and are constructed with an elongated hollow cylindrical shape for peripherally surrounding and protecting products manufactured from elongated tubes, pipes, conduits, and the like. In addition to the product achieved, the present invention also includes a unique process for manufacturing the surface coated cushioning member and systems employed in accordance with the preferred process.
