ABSTRACT:
Disclosed is a hot cup system. The system has a generally cylindrical exterior member with a cylindrical side wall and with an open upper end and an open lower end. The exterior member is molded from a thermally insulating elastomeric material. The system also has a generally cylindrical interior member with a cylindrical side wall with an open upper end and a lower end with a generally planar circular lower portion. The lower portion is formed with laterally spaced downwardly extending parallel projections. The interior member is fabricated of a thermally conductive metallic material. A circular base is next provided with a central section extending downwardly therefrom. The base is fabricated of a resilient clear elastomeric material and is coupled to the interior surface of the exterior member adjacent to the lower end thereof. A chamber is formed between the interior member and exterior member and base. A heat generating fluid is located within the chamber. A generally hemispherically shaped trigger is formed of a flexible metallic material located above the central section of the base.
