ABSTRACT:
A container providing for the separate storage of two materials and the automatic admixing of the materials upon opening of the container. A main container holds a quantity of a first material, such as carbonated water, and a separate compartment holds a small quantity of a second material, such as dipeptide flavoring. In a first embodiment of the invention, a compartmented closure of the twist-on, twist-off type is mounted on the neck of a bottle-shaped container. The closure includes a compartment extending into the container neck, having a hinged bottom closure with a lip which protrudes radially outwardly below the bottle neck. As the closure is unscrewed from the bottle, the lip engages the interior of the bottle neck, causing the hinged bottom to open and thereby release the second material into the main container. In a second embodiment of the invention, a bottle has a twist-on, twist-off type closure which has a compartment for the second material therein. The compartment is stationarily positioned in the neck of the bottle, and the closure includes a movable piercing element which, upon unscrewing of the closure, pierces the stationary compartment to cause the release of the second material into the bottle.
