ABSTRACT:
A cooling system built into a drinking mug. The mug contains a cooling ribbon spirally wound about the interior beverage holding area of the mug. A mobile cylinder container interconnects the ribbon channel with a replaceable nitrogen gas cartridge housed in a vacuum chamber located in the bottom of the mug. The cooling system is hand activated by a spring-loaded mechanism which moves the mobile cylinder container into and out of engagement with the ribbon channel. This arrangement buffers the ribbon channel from the gas cartridge and ensures that only measured amounts of the cooling gas from the gas cartridge are inserted into the ribbon channel. This arrangement also provides a means for supplementing the amount of cooling gas in the ribbon channel.
