Heat-isolating container

Abstract

A container includes a containing main body, and a heat-isolating part positioned around and secured to the containing main body; the heat-isolating part has several spaced apart outwardly-protruding heat-isolating portions, and several inwardly-protruding coupling portions, which are between the outwardly-protruding heat-isolating portions; the heat-isolating part are secured on an outer circumferential side of the containing main body at the inwardly-protruding coupling portions thereof with heat-isolating spaces existing between the containing main body and the outwardly-protruding heat-isolating portions; thus, when a hot drink is contained in the containing main body, high-temperature heat of the hot drink will travel outwards through the containing main body to be absorbed by the air in the heat-isolating spaces, and the hot air will travel outside from the heat-isolating spaces.

1 . An improvement on a heat-isolating container, comprising
 a containing main body, the containing main body having a sealed lower end, and having an opening at an upper end thereof; and   a heat-isolating part positioned around the containing main body, the heat-isolating part having a plurality of spaced apart outwardly-protruding heat-isolating portions; the heat-isolating part having a plurality of inwardly-protruding coupling portions between the outwardly-protruding heat-isolating portions; the heat-isolating part having a smooth connecting portion at a lower end; the heat-isolating part being secured on an outer circumferential side of a lower end of the containing main body at the connecting portion thereof; the heat-isolating part being secured on an outer side of the containing main body at the inwardly-protruding coupling portions thereof with heat-isolating spaces existing between the containing main body and the outwardly-protruding heat-isolating portions; each of the heat-isolating spaces having a through hole at an upper end thereof.   
   
   
       2 . An improvement on a heat-isolating container, comprising
 a containing main body, the containing main body having a sealed lower end, and having an opening at an upper end thereof; and   a heat-isolating part positioned around the containing main body, the heat-isolating part having a plurality of spaced apart outwardly-protruding heat-isolating portions; the heat-isolating part having a plurality of inwardly-protruding coupling portions between the outwardly-protruding heat-isolating portions; the heat-isolating part being secured on an outer side of the containing main body at the inwardly-protruding coupling portions thereof with heat-isolating spaces existing between the containing main body and the outwardly-protruding heat-isolating portions; each of the heat-isolating spaces having a through hole at an upper end, and a through hole at a lower end thereof.   
   
   
       3 . The improvement on a heat-isolating container as recited in  claim 1 , wherein each of the inwardly-protruding coupling portions folds with a line-shape, and is secured on the outer side of the containing main body; thus, an area of contact between the containing main body and each inwardly-protruding coupling portion has a line-shape. 
   
   
       4 . The improvement on a heat-isolating container as recited in  claim 2 , wherein each of the inwardly-protruding coupling portions folds with a line-shape, and is secured on the outer side of the containing main body; thus, an area of contact between the containing main body and each inwardly-protruding coupling portion has a line-shape.
