ABSTRACT:
A capsule containing concentrated detergent liquid or like material has a frangible bottom wall. The capsule which has stiff side walls and a considerably more frangible bottom wall may be mounted in a cradle in the upper or neck portion of a special dispensing container having a removably top closure and the body of which contains a diluent or like liquid such as water and is provided with one or more devices for puncturing the bottom wall of an inserted capsule. In a preferred form the capsule has an annular storage compartment. A formation of the upper end of the capsule coacts with the container closure so that, after insertion of a fresh capsule, mounting of the closure upon the container body displaces the inserted capsule relative to the puncturing devices on the cradle to destroy the frangible bottom wall and empty the capsule contents into the body of the container. In one form the capsule may serve as the container closure.
