Abstract: A cap assembly is provided having a top wall with a first aperture and a second aperture formed therein, a wall member which extends upwardly from at least a portion of the top wall, and first and second closing members both of which are selectively adjustable to a first and a second position. The first closing member comprises a base portion having a channel formed therethrough. When the first closing member is adjusted to its first position it forms a seal across the first aperture. Meanwhile, when the base portion is adjusted to its second position, the channel cooperates with the first aperture to form a passage through the cap. The second closing member also comprises a first portion and a second portion. When the second portion of the second closing member is adjusted to its first position, it forms a seal across the second aperture.

Abstract: A bottle and drinking tube assembly is provided for dispensing of liquids. The bottle has an open top body formed from a resilient plastic material and is adapted to be collapsed upon application of moderate hand pressure and a cap for closing the top through which the bottle is filled. An aperture is formed in the cap for receiving an elongated drinking tube that extends to the bottom of the bottle and has an end exterior of the bottle from which the liquid is discharged. A fluid seal is formed between the cap and tube. A selectively operable venting valve is also provided in the cap to alternatively permit airflow into the bottle enabling the user to sip the liquid through the tube or to prevent fluid outflow from the bottle when the bottle is collapsed to forcibly expel liquid through the tube.
