ABSTRACT:
An electrical device comprising an electrical body in a container with terminals extending through an open end of the container. The electrical body has receptacles at opposite ends thereof. A positioning means is located at an end of the container opposite the open end thereof and projects into a receptacle of the electrical body. An assembly, closing the open end of the container, includes a first layer adjacent the electrical body with a positioning means projecting into a receptacle of the electrical body.
A disc-like member has a positioning means extending therefrom. A recess (or recesses as the case may be) is formed in the disc-like member and provides a membrane adapted to be punctured by a substantially rigid member such as the terminal of the electrical body. Optionally, a vent may be formed in the disc-like member to provide a rupturable elevated pressure release means.
An assembly for closing the open end of the container includes a first layer formed by the disc-like member, a second layer of material curable or cured in situ sealingly contacting the first layer, and a third layer sealingly contacting the second layer.
A method of closing the open end of the container housing the electrical body.
