Abstract
A multiple compartment container and closure assembly with a container having at least two adjacent compartments with end portions terminating in a common surface at one end of the container. The end is sized to accept a cap and the surface has a thin wall portion in communication with each of the compartments. A cap is sized to slidably fit on the end of the container which has puncture means being positioned in alignment with each of the thin wall portions of the container so that movement of the cap from a first position on the end to a second position causes the puncture means to puncture the respective thin wall portion with which it is aligned, to permit access to the contents of the adjacent compartments. A surface of interference on the one end of the container is positioned a predetermined distance from the thin wall portions, and a surface of resistance on the inside of said cap 15 positioned to engage the surface of interference to locate the cap on the end portion at the first position to prevent inadvertent movement of the cap to the second position.
