Abstract
A cap for a container, for a drink of two components, can be stored or carried with the components stored separately. Mixing prior to consumption is effected by a pushing device incorporated into a cover on the cap, which cover is releasably secured to the container. The pushing device bears against a tablet holder the base of which has a low burst of strength. The pushing device can be one of a number of embodiments, all of which can operate with or without an annular cutting ring and flexible seal adjacent the underside of the tablet holder. The cover and tablet holder form a liquid seal with the top of the container until the cover is removed.
