Closure cap having blister pack rupturable upon opening of cap
First Claim
1. A closure cap having a compartment for retaining an additive, the closure cap having a first portion and a body portion defining a push-pull mechanism, said first portion having an aperture, whereby opening of the closure cap is achieved by pulling said first portion of the closure cap relative to said body portion to an open position without said first portion being rotated relative to said body portion, and any additive in said compartment is simultaneously released from the compartment, whereby, in use, any such additive is released into an associated container having liquid contents, whereafter the liquid contents of the associated container may be dispensed through the aperture in said first portion, and wherein closing of the closure cap is achieved by pushing said first portion relative to said body portion to a closed position in which said aperture is closed, whereafter spillage of the contents of the associated container will not occur.

- 20. A closure for a container, the closure having a compartment for holding an additive fluidly isolated from the container by a frangible membrane, a first portion and a body portion, wherein the first portion has an aperture that is sealed by the body portion in a closed position, and wherein non-rotational, axial movement of the first portion away from the body portion to an open position unseals the aperture and forces the additive into and through the frangible membrane to fluidly connect the compartment with the container and release the additive into the container.
- 23. In combination, a closure cap and a container, the closure having a compartment for holding an additive fluidly isolated from the container by a frangible membrane, a first portion and a body portion, wherein the first portion has an aperture that is sealed by the body portion in a closed position, and wherein non-rotational, axial movement of the first portion relative to the body portion to an open position unseals the aperture and forces the additive into and through the frangible membrane and into the container.
