The slidably displaceable sleeve member is located adjacent the liquid containing portion. The liquid containing portion has a bottom surface. The sleeve member has a sidewall and a bottom surface. The sleeve member in a first position has its bottom surface spaced apart from the bottom surface of the liquid containing portion a first distance, while the sleeve member in a second position has its bottom surface spaced apart from the bottom surface of the liquid containing portion a second distance. The drinking container preferably has an upwardly projecting wall having at least one engaging member. Additionally, the sleeve member has a plurality of channels formed in its sidewall. The drinking container is formed having a first wall member and a second wall member, such that the sleeve member is retained between the first and second wall members. The liquid containing portion of the drinking container is configured to hold a maximum predetermined volume of liquid, which volume does not change when the sleeve member is displaced from its first position to its second position. The plurality of channels associated with the sleeve member include a first vertical channel, a second vertical channel, an intermediate horizontal channel connecting the two, and a plurality of horizontal retention channels, each of the horizontal retention channels being connected to the second vertical channel.
