Abstract: A container having two compartments separated by a thermally conductive partition is described. One of the compartments is used for storing a hot beverage and the other compartment is used for storing other items like golf balls that need to be warmed. The heat of the hot beverage can be transferred through the thermally conductive partition to warm other items like golf balls. The same apparatus can also use the coldness of a cold beverage to cool other items like snacks, etc. The upper compartment has a thermally insulated peripheral wall and a thermally insulated lid. The lower compartment has a thermally insulated peripheral wall and a thermally insulated bottom wall. There is a shared thermally conductive wall shared between the upper and lower compartments. The lid in the upper compartment may be opened for adding a hot or cold beverage.
