Temperature keeping container

Abstract

A temperature keeping container includes an inner receptacle and an outer vessel. The inner receptacle is fit in the outer vessel in a tight manner to form an accommodation chamber between the inner receptacle and the outer vessel for receiving and containing a low- or high-temperature medium as desired, or a substance, preferably an edible substance, that is frozen to form a freezing layer, whereby beverage, when deposited in the inner receptacle of the container, can be kept cool to allow a user to enjoy cold beverage of the original flavor, or alternatively, beverage can be poured onto the freezing layer to mix with the substance forming the freezing layer to provide a mixed flavor of beverage.

1 . A temperature keeping container, comprising an inner receptacle and an outer vessel, which are fit to each other to define an accommodation chamber therebetween that receives and contains therein a low- or high-temperature medium, the inner receptacle being removable from the outer vessel. 
     
     
         2 . The temperature keeping container according to  claim 1 , wherein the medium that is received in the accommodation chamber between the inner receptacle and the outer vessel is freezable to form a freezing layer, whereby a beverage is selectively poured into the inner receptacle or directly onto the freezing layer. 
     
     
         3 . The temperature keeping container according to  claim 1 , wherein the inner receptacle has a top end section that is slightly diverging and forms a flange that defines a fitting rim with respect to the inner receptacle and wherein the outer vessel defines an inner bore having an inner circumferential edge that is formed to correspond to the fitting rim so as to allow the fitting rim of the inner receptacle to be fit into the inner circumferential edge of the bore of the outer vessel for coupling the inner receptacle and the outer vessel together in a tight manner. 
     
     
         4 . The temperature keeping container according to  claim 1 , wherein the inner receptacle and the outer vessel form threads that engage each other to detachably couple the inner receptacle and the outer vessel together. 
     
     
         5 . The temperature keeping container according to  claim 1 , wherein the inner receptacle and the outer vessel are integrally formed together to define the accommodation chamber therebetween and wherein the outer vessel has an open bottom in which a thread is formed for selective threading engagement with an inner cup to close the open bottom.
