Abstract
The invention relates to a container assembly comprising fluid, and particularly beverage, cooling and/or mixing means. The cooling and/or mixing is achieved by positioning a movable plunger assembly within the container, the base of which defines notional volume variable upper and lower chambers of the container. The base of the plunger is provided with perforations (and optionally, sealable compartments for sugar, milk etc.) adapted to allow pressurised liquid to be urged from the lower chamber to form upwardly directed jets of liquid in the upper chamber. The invention is particularly advantageous because it allows the consumer to selectively cool and/or mix a beverage by means of a plunging and/or twisting action, thus balancing the demand for hot beverages with the dangers of scalding.
Claims30
A beverage container assembly comprising a container having a reciprocally moveable plunger locatable therein, said plunger having a perforated base member and an actuating member, the base member defining notional volume-variable upper and lower chambers of the container;
- wherein the perforations are spaced apart and adapted to allow a pressurised beverage to be urged from the lower chamber through the perforations to form upwardly directed jets of liquid in the upper chamber during operation of the plunger, characterised in that the actuating member defines an exit passage for said beverage.
A container lid and plunger assembly comprising a plunger having a perforated base member and an actuating member extending from the base member, the perforations being spaced apart such that jets of a pressurised beverage can be urged through the perforations during operation of the plunger, and wherein the actuating member is coupled to a lid, characterised in that the actuating member defines an exit passage for said beverage.
