Sealed galvanic cell

Claim 1

A SEALED GALVANIC CELL COMPRISING A CUPPED METALLIC CONTAINER MADE OF A RIGID METAL AND HAVING AN ELECTROLYTE THEREIN; SAID CELL BEING SEALED AT THE OPEN END OF SAID CUPPED CONTAINER BY A SEAL CLOSURE WHICH COMPRISES A COVER MADE OF A RIGID METAL AND A SEAL RING MADE OF A HARD DI-ELECTRIC PLASTIC-LIKE MATERIAL WHICH IS NOT READILY WETTED NOR DELETERIOUSLY AFFECTED BY SAID ELECTROLYTE AND IS CHARACTERIZED BY A RESISTANT TO COLD-FLOW AND A HIGH COMPRESSIVE AND SHEAR STRENGTH; SAID COVER AND CONTAINER HAVING OPOSITE ELECTRICAL CHARGES, SAID COVER HAVING A SUBSTANTIAL HORIZONTALLY DISPOSED PORTION WHICH TERMINATES AT THE PERIPHERY OF SAID COVER IN A VERTICAL EDGE; SAID SEAL RING HAVING AN ANNULAR, GENERALLY UPSTANDING PORTION HAVING AN INNER VERTICAL SECTION WHICH CORRESPONDS TO SAID VERTICAL EDGE OF SAID COVER AND AN OUTER VERTICAL SECTION WHICH CORRESPONDS TO A SECTION OF SAID CUPPED CYLINDRICAL CONTAINER; SAID ANNULAR UPSTANDING PORTION OF SAID SEAL RING BEING INTERPOSED BETWEEN SAID COVER AND THE INNER SIDEWALL OF SAID CUPPED CONTAINER WITH SAID VERTICAL PORTIONS IN JUXTAPOSITION WITH THE CORRESPONDING VERTICAL PORTION OF SAID CONTAINER SIDEWALL AND SAID COVER; SAID ANNULAR UPSTANDING PORTION BEING IN A STATE OF RADICAL COMPRESSION BETWEEN SAID COVER AND SAID CONTAINER SIDEWALL AND EXERTING A FORCE WHICH IS NORMAL TO SAID VERTICAL PORTIONS OF SAID CONTAINER SIDEWALL, COVER, AND ANNULAR UPSTANDING PORTION, AND PARALLEL TO SAID SUBSTANTIAL HORIZONTALLY DISPOSED PORTION OF SAID COVER; SAID FORCE BEING SUBSTANTALLY EQUIVALENT TO, BUT NOT GREATER THAN THE YIELD STRENGTH OF THE RIGID METAL OF WHICH SAID CUPPED CONTAINER IS FORMED; AND SAID SEAL RING HAVING ANOTHER PORTION INTEGRAL WITH SAID UPSTANDING PORTION WHICH PHYSICALLY AND ELECTROLYTICALLY SEPARATES SAID OPPOSITELY CHARGED COVER AND CONTAINER AT THE POINT OF SEALING FROM ELECTROLYTE CARRYING ELEMENTS OF SAID CELL AND PROVIDES AN ELONGATED ELECTRIC CURRENT PATH BETWEEN SAID OPPOSITELY CHARGED COVER AND CONTAINER WHEN THE SURFACE OF SAID ANOTHER PORTION IS WETTED BY ELECTROLYTE.
