Storage containers for solids and liquids - allows contents to be mixed when one container is screwed to other fitted with discharge nozzle and rupturable membrane

摘要

The container is in two parts and consists of a liquid holder (1) closed by an internal plug (5) which is integral with an outside screw thread (4). The base of the plug has a cutter (6). The other part of the container (7) holds the solids (12) and is fitted with a sealed delivery nozzle (7). The nozzle is closed by a base membrane (13) held by the cap (10). The outside of the container has a cap screwed internally (8) to fit the thread on the other part. Screwing the cap down first causes the membrane (13) to be perforated by the knife (6) and further turns cause the base to the severed from the sides to fall into the liquid.
