Abstract
Abstract A closure assembly consisting of a container and a closure member wherein the container has a heat recoverable portion which cooperates with said closure member to close and seal said assembly. A flange is provided on the closure member which is wider than a corresponding groove on the container. The groove is defined by heat recoverable material and is presented in an expanded state. The closure member may then be heated and inserted in the groove causing the heat recoverable material to shrink about the flange to provide positive closure of the assembly. An adhesive may be incorporated within the groove to further seal the assembly. The closure member most conveniently is a material having a high thermal conductivity to enhance the heating of the heat recoverable material.
