Heat-insulating cup

Abstract

A heat-insulating cup includes a cup, a ring, and a sleeve. The cup includes an open end, a closed end, and a body between the open end and the closed end. The open end has an edge bent outward to form a flange. The ring is securely mounted around an outer periphery of the body and has two open ends. The sleeve is mounted around the ring and includes upper and lower open ends. The upper open end of the sleeve abuts a bottom of the flange of the body. A heat-insulating space is provided between the sleeve and the body to effectively avoid a hand of a user from high heat.

1 . A heat-insulating cup comprising:
 a cup including an open end, a closed end, and a body between the open end and the closed end, with the open end having an edge bent outward to form a flange;   a ring securely mounted around an outer periphery of the body, with the ring including two open ends, with the ring further including a plurality of holes; and   a sleeve mounted around the ring and including upper and lower open ends, with the upper open end of the sleeve abutting a bottom of the flange of the body,   with the plurality of holes of the ring forming a heat-insulating space between an inner periphery of the sleeve and the outer periphery of the body.   
   
   
       2 . The heat-insulating cup comprising as claimed in  claim 1 , with the ring being made of resilient material. 
   
   
       3 . A heat-insulating cup comprising:
 a cup including an open end, a closed end, and a body between the open end and the closed end, with the open end having an edge bent outward to form a flange;   a plurality of rings securely mounted around an outer periphery of the body and spaced from each other, with each of the plurality of rings including two open ends, with an annular heat-insulating space being formed between two of the plurality of rings adjacent to each other; and   a sleeve including upper and lower open ends and mounted around the ring, with the upper open end of the sleeve abutting a bottom of the flange of the body.   
   
   
       4 . The heat-insulating cup comprising as claimed in  claim 3 , with the rings being made of resilient material.
