BEVERAGE FROTHING DEVICE

摘要

A beverage frothing device for a beverage container for production of a foamy dispersion of bubbles or "head" within a liquid packaged within sealed, non-resealable cans or other containers. The beverage frothing device has a fluid chamber formed by two generally hollow telescopically slidable members (301, 302) which have means for securing (308, 317) the two members (301, 302) in a telescopically compressed position. Means (314) are also provided for fluid communication between the fluid chamber and the exterior of the device in response to a predetermined reduction in the pressure external to the device. A cage arrangement with a plurality of arms (305) is disposed around the two members (301, 302) such that the arms (305) curve away from the members (301, 302) and exert a force against the insides of the beverage container when the two members (301, 302) are telescopically compressed thereby holding the device in place in the beverage container.
