ABSTRACT:
An improved beverage container for dispensing carbonated beverages, for example. The container is provided with a housing shell having a lid of unique design, and also an interior apertured container suitable for receiving dry ice or other solid cooling agent. This interior apertured container is uniquely provided with an annular wall having slots that can be readily produced in an injection molding operation. A ring is provided both to preserve the integrity of this interior container and also to serve as a support for co-action with a lid of the beverage housing shell. The housing shell itself is provided with a lid having a baffle, the same being provided with gas vents and having a baffle beneath such vents for preventing the contained fluid from sloshing about proximate the vents and also for generally retaining foam beneath the baffle area. The baffle itself, however, is provided with a series of apertures to provide gaseous communication as between the interior of the beverage container and the gas vents of the lid. The baffle is either flat or disc shaped, the latter being especially useful for return of condensations that might appear upwardly of such baffle through use of the container.
