Thermal container

Abstract

A thermal container includes a cover, a main body, an opening-closing assembly, and a plurality of support poles. The main body has a storage space therein. The opening-closing assembly includes an upper connecting member and a lower connecting member. The lower connecting member is hermetically connected to the main body. The upper connecting member is hermetically connected to the cover. The support poles are vertically arranged in the main body for supporting the lower connecting member. The support poles, the upper connecting member and the lower connecting member are made of a hard material. The overall supporting strength of the thermal container is improved.

What is claimed is: 
     
         1 . A thermal container, comprising a cover, a main body, an opening-closing assembly, and a plurality of support poles;
 the main body having a storage space therein;   the opening-closing assembly including an upper connecting member and a lower connecting member; the lower connecting member being hermetically connected to an opening of the storage space, the lower connecting member having a through hole communicating with the storage space; the upper connecting member being hermetically connected to the cover, the upper connecting member being provided with a protruding portion matching the through hole, the protruding portion being movably, hermetically fitted in the through hole;   the support poles being vertically arranged in the main body, upper ends of the support poles supporting an underside of the lower connecting member;   the support poles, the upper connecting member and the lower connecting member being made of a hard material.   
     
     
         2 . The thermal container as claimed in  claim 1 , wherein the cover and the upper connecting member as well as the main body and the lower connecting member are connected in a sealed manner by bonding. 
     
     
         3 . The thermal container as claimed in  claim 1 , wherein the cover includes a first outer layer, a first interlayer and a first inner layer that are stacked in sequence. 
     
     
         4 . The thermal container as claimed in  claim 3 , wherein the main body includes a second outer layer, a second interlayer and a second inner layer that are stacked in sequence, and the support poles are arranged between the second outer layer and the second inner layer. 
     
     
         5 . The thermal container as claimed in  claim 4 , wherein the main body is in the form of a box; the number of the support poles is four, and the four support poles are arranged at four corners of the main body, respectively. 
     
     
         6 . The thermal container as claimed in  claim 5 , wherein the second interlayer after being folded is formed with pole cavities at corner positions of the second interlayer for the support poles to be fitted therein. 
     
     
         7 . The thermal container as claimed in  claim 5 , wherein a side wall of each support pole is formed with a groove for insertion of the second interlayer. 
     
     
         8 . The thermal container as claimed in  claim 1 , wherein rear ends of the upper connecting member and the lower connecting member are pivotally connected together, front ends of the upper connecting member and the lower connecting member are provided with a locking mechanism; the locking mechanism includes a hook disposed on the front end of the upper connecting member and a catching portion disposed on the front end of the lower connecting member, when the upper connecting member and the lower connecting member are closed, the hook is buckled to the catching portion. 
     
     
         9 . The thermal container as claimed in  claim 1 , wherein the opening-closing assembly further includes a sealing ring; a side wall of the through hole is provided with an annular step, one side of the step, facing the protruding portion, is formed with an annular flange, the sealing ring is fitted onto the flange; when the upper connecting member and the lower connecting member are closed, the protruding portion is in contact with the sealing ring and compresses the sealing ring to be deformed. 
     
     
         10 . The thermal container as claimed in  claim 1 , wherein the hard material is an injection moldable plastic material. 
     
     
         11 . The thermal container as claimed in  claim 1 , wherein the main body includes a second outer layer, a second interlayer and a second inner layer that are stacked in sequence, and the support poles are arranged between the second outer layer and the second inner layer.
