Abstract
A container for separate storage includes a receptacle for a liquid product, a retaining sleeve having a detachable capsule integrally molded therewith to be separated by tearing of a rupturable wall portion joining the capsule and sleeve for releasing an additional product in the capsule into the liquid product as the capsule falls into the receptacle, and a stopper including a dispensing spout. The stopper is fixed to the retaining sleeve for conjoint rotation around the receptacle neck, and the capsule and the receptacle neck have interengageable reliefs to hold the capsule against rotation whereby twisting the stopper will rotate the sleeve to tear the rupturable wall portion, releasing the capsule. Mixing of the two products may be assisted by the user shaking the container, and the ensuing mixture may be dispensed through the stopper spout.
