Abstract

Electrochemical cell, of the type comprising an anode, a cathode, electrolyte and a separator, all arranged in a metal container having an open end, a bead formed in said container near said open end and a hard and resistant plastic cover to the cold flow that seals said open end, characterized in that, for purposes of sealing, said plastic cover, which is greater than said open end, is forced through a reducing matrix to develop a radial force in the plastic cover and into the open end of said metal container wherein said plastic cap is expanded to come into contact with said metal container; the upper wall of said metal container is deformed outwardly above said bead by means of said radial force in the plastic cap; and the upper edge of said metal container, which is crimped onto the upper surface of said plastic cap, is compressed axially by means of a conical sealing die, whereby said plastic cap exerts an axial force and a radial force against said metallic container and forms an area of axial sealing and radial sealing.
