摘要

A novel cup is disclosed that may be collapsed and extended to hold cold or hot liquids safely. The cup preferably comprises a telescoping body comprising a plurality of rings of varying outer diameters, each ring having an outer wall and an inner wall forming an air gap therebetween, a leak-proof mechanism comprising an O-ring disposed about one or more rings, and a locking mechanism comprising an annular track disposed about one ring, and a pin disposed about another ring adapted to fit within the track and slideably engage it. The locking mechanism may further comprise a first magnet seated within the air gap of a first ring, and a second magnet seated within the air gap of a second ring, whereby the first and second magnets create a magnetic pull toward one another to help keep the cup in either a collapsed or extended position.
