A closure for a container wherein a tape having a metal part and thermoplastic material which is applied to the container wall and heated. Most of the material is squeezed out from between the metal part and the wall into a rib which is formed during application. The material in the rib has an isotropic structural characteristic since the rib formation provides a region into which the excess material is directed minimizing the shearing effect of the flow of material along the interface with the container wall. Also the rib reinforces the tape in the critical region to resist pressure of gasses in the container when used to contain carbonated beverages. This patent covers a method of making the above described closure.
