Two-layer thermal container

Abstract

A two-layer thermal container according to the present invention comprises an outer container having a first intake port at an upper end thereof and an opening at a lower portion thereof; an inner container as a cylindrical body having a second intake port formed at an upper end thereof and inserted into an opening of the outer container with the outer circumferential surface of the second intake port being in close contact with the inner circumferential surface of the first intake port; a sealing member assembled to the opening to seal the opening and having its upper surface contacted with the bottom surface of the inner container; and an insertion stopper inserted into the second intake port of the inner container to seal the second intake port.

What is claimed is: 
     
         1 . A two-layer thermal container comprising:
 an outer container having a first intake port at an upper end thereof and an opening at a lower portion thereof;   an inner container as a cylindrical body having a second intake port formed at an upper end thereof and inserted into an opening of the outer container with the outer circumferential surface of the second intake port being in close contact with the inner circumferential surface of the first intake port;   a sealing member assembled to the opening to seal the opening and having its upper surface contacted with the bottom surface of the inner container; and   an insertion stopper inserted into the second intake port of the inner container to seal the second intake port.   
     
     
         2 . The two-layer thermal container according to  claim 1 ,
 wherein the outer container comprises a single wall or multi-layer wall, and the volume of air between each layer wall is between a vacuum state and an atmospheric pressure state when the wall is comprised of multi-layer wall.   
     
     
         3 . The two-layer thermal container according to  claim 1 ,
 wherein the sealing member has a built-in refrigerant.   
     
     
         4 . The two-layer thermal container according to  claim 1 ,
 wherein the sealing member includes an outer case having a first lateral ventilation window formed on a lateral surface thereof and an inner case having a first corresponding ventilation window formed on a lateral surface thereof, the first lateral ventilation window and the first corresponding ventilation window are communicated and sealed repeatedly, a bottom ventilation window is formed on the bottom of the inner case, a bottom circular plate which is freely rotatable is provided on the top surface of the bottom, and a corresponding bottom ventilation window corresponding to the bottom ventilation window is formed on the bottom circular plate to have the bottom ventilation window and the corresponding bottom ventilation window communicated and sealed repeatedly by rotation of the bottom circular plate.   
     
     
         5 . The two-layer thermal container according to  claim 4 ,
 wherein a bottom handle is hinge-coupled to the inner circumferential surface of the corresponding bottom ventilation window of the bottom circular plate.   
     
     
         6 . The two-layer thermal container according to  claim 1 ,
 wherein the outer container has a second lateral ventilation window formed along the circumference of the lateral surface, a rotary opening and closing cylinder having a second corresponding ventilation window formed thereon along the circumference of the cylinder is installed on the inner circumferential surface of the outer container and is in a close contact with the inner circumference of the outer container and rotatable, a guide which rotationally support the rotary opening and closing cylinder are formed on the inner circumferential surface of the outer container in such a way that the guide is in contact with the upper and lower portions of the rotary opening and closing cylinder, and the second lateral ventilation window and the second corresponding ventilation window are communicated and sealed repeatedly by rotation of the rotary opening and closing cylinder.   
     
     
         7 . The two-layer thermal container according to  claim 6 ,
 wherein a lateral handle is installed in the inner circumferential surface of the second corresponding ventilation window by a hinge coupling to the inner circumferential surface of the second corresponding ventilation window.   
     
     
         8 . The two-layer thermal container according to  claim 1 ,
 wherein some portion of the lateral surface area of the outer container is cut so that the inside and the outside of the outer container are communicated with each other to form a third lateral ventilation window, a lateral surface cover is provided to close the third lateral ventilation window, a connecting arm is provided in such a way that each end of the connecting arm is hinge-coupled to one end of the lateral surface cover and the inner circumferential surface of the third lateral ventilation window respectively, and accordingly the lateral surface cover opens and closes the third lateral ventilation window by variableness of the connecting arm.   
     
     
         9 . The two-layer thermal container according to  claim 8 ,
 wherein a variable plate protruding by an elastic force of an elastic body provided inside the lateral surface cover is provided on one end of the lateral surface cover, an assembly groove into which an end of the variable plate is inserted is provided in the inner circumferential surface of the third lateral ventilation window, and a switch which is integrally formed with the variable plate is provided on the surface of the lateral surface cover so as to pull back the variable plate.
