Patent attributes
A self-anchoring beverage container with directional release and attachment capability has a flexible nonporous base member adapted to seal to a reference surface and create a controlled pressure zone. A receptacle assembly is mounted to the base member and includes a beverage holding chamber. A communication channel in the receptacle assembly extends from the controlled pressure zone to an area of ambient pressure. A pressure control device on the receptacle assembly is adapted to alternately close the communication channel to seal the controlled pressure zone and open the communication channel to vent the controlled pressure zone to ambient pressure. The receptacle assembly further includes a grasping portion arranged to be grasped by a user. The pressure control device is operatively connected to the grasping portion for actuation to the open position when a user grasps the grasping portion during normal lifting of the beverage container from the reference surface.
