Patent Images
1. A thermal cup comprising:
- a hollow inner cup body having an open mouth and a closed bottom, said inner cup body including an inner surrounding wall and an outer surrounding wall that confine an enclosed chamber therebetween, said inner surrounding wall further confining a space for containing liquid therein;
an outer cup body made of a heat insulating material, disposed to surround said outer surrounding wall of said inner cup body, and cooperating with said outer surrounding wall of said inner cup body to confine a clearance therebetween; and
a thermal conductor unit provided on said outer surrounding wall of said inner cup body and disposed in said clearance.

Abstract
A thermal cup includes a hollow inner cup body having an inner surrounding wall and an outer surrounding wall that confine an enclosed chamber therebetween, and an outer cup body made of a heat insulating material and disposed to surround the outer surrounding wall of the inner cup body. The inner surrounding wall further confines a space for containing liquid therein. The outer cup body cooperates with the outer surrounding wall of the inner cup body to confine a clearance therebetween. A thermal conductor unit is provided on the outer surrounding wall of the inner cup body, and is disposed in the clearance.
