Abstract
The present invention relates to a drinking container for increasing the number of and ostensibly decreasing the size of bubbles in a drinking liquid having dissolved gases contained therein. The container is provided with a roughened region on its normally smooth interior surface. The roughened region is preferably located at the bottom of the container and may be produced by grinding, sand blasting, acid etching, and the like. It is a feature of the disclosure that the roughened region may be formed of a separate element mechanically locked to the container.
Claims2
A drinking container for improving the drinking quality of beverages having dissolved gases, comprising means for inducing the release of the carbonation contained within said beverage, said means comprising a roughened surface area on the interior surface of said container, said roughened surface area being produced by a process selected from the group consisting of acid etching, sand blasting, and grinding, said roughened surface area being not less than 1%, nor more than 50%, of the interior surface area of said container, said roughened area substantially increasing the interior surface area of said container while maintaining relatively constant the interior volume of said container, said drinking container being between 6 and 12 ozs. and the roughened surface area being located at the bottom of said container and being between 1 and 3 centimeters in diameter or the equivalent in area.
