Abstract
1506579 Leak resistant dry cells CHINE WA PUN and CHINE CHAU POON 16 Oct 1975 45042/74 Heading H1B A dry cell comprises a negative electrode formed by a zinc tube open at both ends, a sealed bag of flexible plastics material enclosing said zinc tube and surrounded by a cylindrical jacket, a carbon anode projecting from one end of the cell through a first opening in said bag in sealing relation thereto, at least one tongue extending, at the other end of the cell, from said zinc tube through a second opening in said bag in sealing relation thereto, and a conductive plate, forming the negative terminal of the cell, at said other end of the cell, said tongue making electrical contact with said conductive plate inside the cell. In making the cell, a paper 8 saturated with electrolytic paste is laid on a flat zinc sheet 2; this combination is rolled around the depolarizing dolly 9, and the resulting body is put in a plastics bag, e.g. of a polyolefin such as polyethylene or polypropylene or a vinyl resin such as PVC, open at side 3 and having an entry at 6 for the tongue 1 of the zinc sheet; the bag is then sealed by heat or high frequency welding on line 10, and entry 6 is sealed to tongue 1 either by adhesive 7 of asphalt, wax, sealing wax, silicone rubber or resin, or else tongue 1 is pre-treated with varnish or lacquer and heat-sealed to 6. A cylinder of metal, paper, or cardboard is then put around the plastics bag and the carbon electrode pushed (on axis 14) into the dolly; where the electrode penetrates the bag a seal is made using adhesive as at 7. Tongue 1 is then bent over, terminals are attached at the top and base of the cell and the cell sealed conventionally (Figs. 5 and 6, not shown).
