ABSTRACT:
A telescopic straw assembly has an outer straw with a collar of reduced diameter at one end through an inner straw of smaller diameter can be withdrawn to increase the length of the straw with a minimum resistance. The inner end of the inner straw has an intermediate portion adjacent its inner end of a larger diameter which is designed to be pulled telescopically into the outer straw's collar portion and in so doing expand the collar portion to provide an airtight seal and firmly hold the straws together. The straws have additional interengaging features to further stabilize them both axially and radially when in extended position.
