ABSTRACT:
An easy-to-operate vented leak-proof drinking cup cap for a bottle is formed by a pivotable drinking spout (3) and diaphragm arrangement (4) in the cap base (7). The drinking spout that forms the mouthpiece on the upper side of the diaphragm through which the user sucks liquid, contains a portion (3b) on the underside the diaphragm. That lower spout portion carries an elastic hose or tube (8) for immersion in the bottle's liquid when the drinking spout is in the open position, whereby the series of passages through the elastic tube and drinking spout serves as a straw. When the spout is pivoted to its closed position and latched, in one movement, the lower portion of the spout swings a portion of the elastic tube against the vent (6), closing the vent, and forces another portion of that hose into an interference surface (12), creating a bend or kink in the hose that prevents liquid passage.
