Abstract
Abstract A double-walled drinking vessel having a heat maintenance chamber between an inner wall and outer, transparent, wall of the vessel. A fluid is placed between the walls, and this fluid is either heated or cooled, depending upon the beverage that is to be employed in the vessel. An annular base in the form of a skirt is placed around and below the bottom of the vessel, and it has a plurality of spaced orifices which provide for air circulation underneath the vessel, this preventing condensation from occurring on a tabletop or other supporting surface. The state of the temperature maintenance chamber is viewable through the transparent outer wall.

Claim 1
Independent Claim
163 words
A drinking container assembly comprising: a circular-shaped tumbler; a transparent cylinder surrounding the sides, and extending below, said tumbler and spaced from said tumbler, and a top of said tumbler and cylinder being sealably connected; a bottom closure extending across and closing a bottom end of said cylinder and spaced from the bottom of said tumbler; a filling neck member centrally positioned on, and extending below, said bottom closure and having a central opening through said bottom closure, and said filling neck member having a threaded region about said opening; a threaded closure adapted to mate with and sealably close said filling neck member; a skirt attached to and extending down from an outer region of said bottom closure and extending below said filling neck member to provide a base support for said assembly; a series of spaced openings around and through said skirt, enabling air circulation under the bottom of said container; and a handle attached to the side of said cylinder.
Claim 2
Dependent Claim
163 words
A drinking container assembly comprising: a circular-shaped tumbler; a transparent cylinder surrounding the sides, and extending below, said tumbler and spaced from said tumbler, and a top of said tumbler and cylinder being sealably connected; a bottom closure extending across and closing a bottom end of said cylinder and spaced from the bottom of said tumbler; a filling neck member centrally positioned on, and extending below, said bottom closure and having a central opening through said bottom closure, and said filling neck member having a threaded region about said opening; a threaded closure adapted to mate with and sealably close said filling neck member; a skirt attached to and extending down from an outer region of said bottom closure and extending below said filling neck member to provide a base support for said assembly; a series of spaced openings around and through said skirt, enabling air circulation under the bottom of said container; and a handle attached to the side of said cylinder.
Claim 3
Dependent Claim
