Abstract:
Apparatus for separately storing and subsequently mixing first and second components of a substance to be dispensed, the apparatus comprising a container defining a chamber for receiving the first component, a closure member rotatably mounted about a tubular neck of the container to close an outlet of the container defined by said neck, a vial comprising a first portion formed integrally with the closure member and a second portion releasably connected in sealing engagement with the first portion to define therebetween a compartment for receiving the second component, and vial opening means comprising co-operating cam formations on the closure member and the second portion of the vial actuatable by co-axial rotational movement of the closure member about the container neck to move the second portion out of sealing engagement with the first portion to thereby establish communication between the chamber and the compartment for mixing of the first and second components, and wherein the cam formations comprise a helical cam surface defined by a projection of the closure member and co-operating cam member of the second portion of the vial, and means are provided on the internal wall of the container and co-operating with the cam member to prevent rotation of the second portion relative to the container during opening such that rotational movement of the closure member displaces the cam member axially in a direction away from the first portion of the vial.
