1. Field of the Invention
The present invention relates generally to drinking straws and, more specifically, to a disposable drinking straw having a plurality of air bladders constructed to be integral with the internal throughbore of said straw in order to cause the straw to rise up and partially out of a fluid or sanitary container, such as a can or bottle, utilizing buoyancy of trapped air to make facilitation of an immersed buoyant straw more practical and easier to gain use thereof.
The straw of the present invention may be utilized on its own or packaged within a beverage container in order to rise out of the container when the container is opened.
Additionally the straw has a flexible portion for bending to an ideal location for use, along with its air bladders being constructed in a plurality of manners for increased or decreased buoyancy including a sole bottom air bladder, a plurality of air bladders and finally an air bladder extending the entire length of the inner periphery of the straw.
The present invention is composed of minimal material, no mechanical parts and in a thin small profile that can be produced in any length, shape, color or size utilizing preexisting manufacturing and packaging methods. Additionally the present invention can be utilized with any beverage or container and allows for enhancement of the marketing potential of any beverage by including the device inside of a sealed beverage or taped to the side of a beverage container.
