Cell sealing means

An electrical device comprising a container with an opening in one end thereof;

• a mobile fluid electrolyte in said container;
• a single top closure member at the open end of the container said closure member extending for a substantial distance within said container in spaced relation thereto;
• a resilient sealing grommet in spaced relation to and encircling the closure member to form an enclosed annular space between said grommet and said closure member;
• said sealing grommet being compressed between said closure member and the inner wall of said container at the upper end of said grommet to complete the closing of the open end of said container;
• whereby two potential electrolyte leakage paths exist, a first path between said grommet and said closure member which includes said annular space and a second between said grommet and the interior of said container;
• means to inhibit electrolyte leakage along said second path between said grommet and the interior of said container whereby electrolyte leakage is directed to said first path between said grommet and said closure member;
• and said first path having contained therein, in said annular space, a body of non-reactive material capable of absorbing said electrolyte.
