ABSTRACT:
An automatically sealing cup composed generally of a cup body, a lid sealingly and releasably connected with the cup body, and an automatic sealing feature that includes, generally, a flexible tube communicating with the interior space of the cup body, an aperture in the lid through which the flexible tube sealingly passes, a pivotable handle associated with the lid wherein the position of the handle determines pinching or unpinching of the tube, and, consequently, sealed and open states, respectively, of the automatically sealing cup, and a biasing member associated with the lid which automatically biases the handle to provide the sealed state. To switch the automatically sealing cup to the open state in which liquid may be extracted therefrom through the tube, a user must continuously apply pressure to the handle, upon the cessation of which the automatically sealing cup automatically reverts to the sealed state.
