Abstract
A cover for fitting over the open end of a can, glass, cup or carton type beverage container which employs a straw extending into the container for siphoning liquid therefrom and an impeller mounted in a trough in the housing forming a part of the cover for connecting to and rotating a display device, the improvement including the utilization of an air stream into the cover and against the impeller created by the negative pressure created in the container upon withdrawal of beverage therefrom for rotating the impeller.
Claims12
An amusement drinking device for mounting on a beverage container and operable upon withdrawal of the beverage from the container comprising:
- a cover for fitting over the open end of a beverage container in an airtight arrangement,
- said cover having a port for receiving a straw extending therethrough and into the beverage in an airtight arrangement,
- an impeller journalled in said cover for rotation thereof and forming with an exposed surface of said cover a housing therebetween, said impeller being actuated by jets of air drawn into said housing upon withdrawal of beverage from the container through the straw,
- said cover defining a circular trough in said exposed surface thereof,
- said impeller having at least a series of sequentially arranged parts mounted in a circle for positioning in said trough,
- said housing defining an inlet port and an outlet port,
- said inlet port being open to atmospheric pressure and formed to direct a series of jets of incoming air against said parts of said impeller in said trough and an outlet port for discharging said air from said housing into the associated beverage container,
- whereby suction created in the associated container upon withdrawal of beverage therefrom through the straw creates a negative pressure in said housing which causes said jets of air to be drawn into said trough in said housing, directed against said parts of said impeller causing rotation of said impeller and into the associated container.
