Abstract: An apparatus for dispersing a substance in a liquid beverage contained in a container includes a receptacle containing the substance formed in the interior of the container and an opening tab attached to the top of the container for bursting the receptacle to disperse the substance and for opening a pour panel in the top of the container so that the liquid beverage can be drunk from the container. The receptacle is formed of a flat sheet of an elastic material that is joined at opposite edges thereof to form a burstable seam. One end of the receptacle is a beak that causes the seam to burst upon engagement with the opening tab.

Abstract: An apparatus for opening a container and for dispensing a substance in a liquid beverage contained in a container includes a flat portion defining a wedge-shaped cut-out, side portions that extend downwardly from the flat portion, and an opening lever attached to the flat portion. The opening lever may include a receptacle containing the substance to be dispensed, a burstable material covering one end of the opening lever, and a plunger attached at an opposite end of the opening lever. The plunger is pushed to compress the substance and break the burstable material to dispense the substance. Otherwise, the opening lever contains no receptacle and is used simply to open the pour panel formed in the top of the container or a tearable receptacle is attached to an underside of the flat portion at a position corresponding to the cut-out so that the opening lever tears open the receptacle and releases the substance contained therein.

The receptacle can be formed in the top of the container such that it is upwardly openable so that a dispenser containing the substance to be dispensed can be added to the receptacle after the container has been manufactured.
