Thermobottle

Abstract

A thermobottle includes an outer mug, a sleeve, an inner mug and a cover. The sleeve includes a first abutting portion. The inner mug is sleeved within the sleeve. The first abutting portion abuts against an inner wall of the outer mug to accommodate the inner mug within the outer mug. The cover includes a second abutting portion which has the same shape and dimensions as the first abutting portion. The second abutting portion abuts against an inner wall of the inner mug or the inner wall of the outer mug. When the second abutting portion abuts against the inner wall of the outer mug, the cover seals the outer mug with the inner mug removed. When the second abutting portion abuts against the inner wall of the inner mug, the cover seals the inner mug.

What is claimed is: 
     
         1 . A thermobottle, comprising:
 an outer mug;   a sleeve comprising a first abutting portion;   an inner mug at least partially sleeved within the sleeve, the first abutting portion being configured to abut against an inner wall of outer mug to allow the inner mug to be at least partially accommodated within the outer mug; and   a cover comprising a second abutting portion, the second abutting portion and the first abutting portion substantially having same shape and dimensions, the second abutting portion being configured to abut against an inner wall of the inner mug or the inner wall of the outer mug,   wherein when the second abutting portion abuts against the inner wall of the outer mug, the cover seals the outer mug with the inner mug removed from the outer mug, when the second abutting portion abuts against the inner wall of the inner mug, the cover seals the inner mug.   
     
     
         2 . The thermobottle of  claim 1 , wherein the inner mug comprises:
 a first mug body having a first inner diameter, the first abutting portion corresponds with the first mug body;   a second mug body having a second inner diameter, the second inner diameter is larger than the first inner diameter; and   a third mug body connected between the first mug body and the second mug body.   
     
     
         3 . The thermobottle of  claim 2 , wherein the first abutting portion surrounds to form an annular shape. 
     
     
         4 . The thermobottle of  claim 2 , wherein the first mug body and the third mug body are located within the sleeve, the second mug body is at least partially located outside the sleeve. 
     
     
         5 . The thermobottle of  claim 1 , wherein the cover comprises:
 a main body having a through hole; and   a flip cover pivotally connected with the main body and configured to seal the through hole.   
     
     
         6 . The thermobottle of  claim 1 , wherein the outer mug comprises an outer structure and an inner structure, the outer structure and the inner structure are at least partially separated from each other and define an insulating space therebetween. 
     
     
         7 . The thermobottle of  claim 1 , wherein the outer mug and the inner mug are made of different materials. 
     
     
         8 . The thermobottle of  claim 1 , wherein the outer mug is made of stainless steel. 
     
     
         9 . The thermobottle of  claim 1 , wherein the inner mug is made of porcelain. 
     
     
         10 . The thermobottle of  claim 1 , wherein the sleeve is made of silicon. 
     
     
         11 . A thermobottle, comprising:
 an outer mug comprising a first coupling portion;   a sleeve comprising a second coupling portion;   an inner mug at least partially sleeved within the sleeve, the inner mug comprising a third coupling portion, the second coupling portion being configured to detachably couple with the first coupling portion to allow the inner mug to be at least partially accommodated within the outer mug, the third coupling portion and the first coupling portion substantially having same shape and dimensions; and   a cover comprising a fourth coupling portion, the fourth coupling portion and the second coupling portion substantially having same shape and dimensions, the fourth coupling portion being configured to suitably couple with the first coupling portion or the third coupling portion,   wherein when the fourth coupling portion couples with first coupling portion, the cover seals the outer mug with the inner mug removed from the outer mug, when the fourth coupling portion couples with the third coupling portion, the cover seals the inner mug.   
     
     
         12 . The thermobottle of  claim 11 , wherein the first coupling portion is disposed on an outer wall of the outer mug, the inner mug comprises:
 a first mug body having a first inner diameter;   a second mug body having a second inner diameter, the second inner diameter is larger than the first inner diameter, the third coupling portion is disposed on an outer wall of the second mug body; and   a third mug body connected between the first mug body and the second mug body, the sleeve comprises:
 an inner ring surrounding and connecting with an outer wall of the first mug body; 
 an outer ring, the second coupling portion is located on a side of the outer ring facing to the inner ring; and 
 a supporting portion connected between the inner ring and the outer ring, and configured to be at least partially supported by an edge of the outer mug. 
   
     
     
         13 . The thermobottle of  claim 12 , wherein the first coupling portion is an external thread structure, the second coupling portion is an inner thread structure. 
     
     
         14 . The thermobottle of  claim 12 , wherein the inner ring has a first snapping portion disposed on a side of the inner ring facing to the outer ring, the outer mug has a second snapping portion disposed on an inner wall of the outer mug, the first snapping portion and the second snapping portion are configured to snap with each other. 
     
     
         15 . The thermobottle of  claim 12 , wherein the first mug body is at least partially located within the inner ring, the second mug body is located outside the inner ring. 
     
     
         16 . The thermobottle of  claim 11 , wherein the outer mug comprises an outer structure and an inner structure, the outer structure and the inner structure are at least partially separated from each other and define an insulating space therebetween. 
     
     
         17 . The thermobottle of  claim 11 , wherein the outer mug and the inner mug are made of different materials.
