1,193,566. Portable containers. PENNSALT CHEMICALS CORP. 2 Dec., 1968 [12 Dec., 1967], No. 56983/68. Heading B8D. A capsule for separately storing two ingredients which are to be mixed prior to dispensing comprises a tube A having an integral partition B which has intersecting weakening lines dividing it into segments. A tubular member C telescopically slides into the tube A to form one chamber, and a cap D closes the other end of the tube A to form a second chamber. The member C has a chamfered end 28 and is pushed inwardly to rupture the partition along the weakening lines when the contents are to be mixed. The outer diameter of the inner end of the member C may be reduced to facilitate accommodation of the segments of the partition between the external surface of the member C and the inner surface of the tube A, the chamfered end 28 sealingly engaging the cap D. The ingredients, which may be silver powder 34 and mercury 38 can then be triturated with the aid of a pestle 36 to form a dental amalgam. The cap D is removed to dispense. As shown, the cap is a tight sliding fit on the tube, alternatively it may threadedly engage the tube. The relief afforded by threading the end of the tube permits expansion of the tube to accommodate the ruptured partition. |
