Sipper With Built-in Refrigerant (Nov, 1950)
Sipper With Built-in Refrigerant
Every swallow is chilled when drinks are sipped through a novel aluminum tube containing a sealed-in refrigerant and tipped with a Tenite plastic mouthpiece and end. The sipper is kept in the freezing compartment of the refrigerator prior to use and its contents allowed to freeze solid. There is no dilution of the beverage and the plastic mouthpiece protects lips from frostbite. It is made in several colors and is easily cleaned and dried.
