Heat treatment cup for a beverage container

DETAILED DESCRIPTION ACCORDING TO THE PREFERRED EMBODIMENTS OF THE PRESENT INVENTION FIGS.
1 and 2 show a heat treatment cup and in particular a cooler cup generally indicated at 1 for receiving a beverage container.
Although the drawings show a beverage can, it is to be appreciated that a bottle or even a glass can also be used with the heat treatment cup of the present invention.
The cooler cup comprises an internal sleeve 3 and an external insulating cover 5.
The sleeve, which has a hollow construction, is filled with a non-toxic freezer gel 4 sealed within the sleeve.
In order to temperature condition the cup, i.
e.
bring it down to a cold temperature, it is simply placed in a refrigerator or freezer to lower the temperature of the gel in the sleeve which will then remain at its lowered temperature because of the insulating properties of cover 5.
Also, the sleeve is isolated from any outside warming influences when the beverage can itself is fitted in position because the mouth of the cup, defined by inwardly extending ring 7, tightly grips on the beverage container and the container, when fully inserted, seats on the bottom portion 11 of the insulating cover.
Accordingly, because there is no travel of air into or out of the cooler when the beverage container is in position, a dead air space 6 is trapped between the container and the cooling sleeve.
Therefore, the container acts as a sealing member and the insert is subject to very little heat pick up while providing a cooling effect on the beverage container.
As will be seen in FIGS.
1 and 3, the height of the cup is dimensioned to provide very little exposure of the container to keep heat pick up of the container from the ambient air to a minimum.
The insert itself can be reduced to a temperature where gel 4 actually freezes and although the purpose of the insert is to provide a cooling effect, it should not come into contact with the container which might otherwise freeze the beverage in the container.
Accordingly, ring 7 of the insulating cover not only grips the can but provides the required spacing element for keeping the container and the insert out of contact with one another as shown in FIG
