Abstract
Abstract A container having material in solid form into which a liquid is to be added to dissolve the material and produce a liquid preparation such as a beverage. The container has an opening in its bottom which is sealed and the solid material is located in the bottom of the container sealed off to the atmosphere by a member of dissolvable material. A liquid is poured into the open top of the container to dissolve both the member and the material. The top is then covered and the container is inverted. The seal is removed from the opening in the bottom wall and the mixed contents of the container withdrawn through this opening.
