Abstract
A dispensing container for combining and then dispensing two discrete materials includes a first open top container element for containing the first material, e.g. a fluid and a second container element having closed upper and lower ends for containing the other of the two materials, e.g. a powder or a liquid. The second container element is dimensioned to be telescopically received with its lower end within the open topped container element. A valve is provided in the lower end of the second container element for normally keeping the materials in the container elements separate but permitting fluid in the first container element to flow into the second container element upon depression of the second container element, thereby causing materials in the two containers to combine. The upper end of the second container element may be provided with a removable cover so that the mixed materials can be dispensed.
