Patent attributes
The present invention relates to a straw (1), a straw assembly (2) and a cup assembly (3). The straw (1) comprises first holes (13) in an upper half and second holes (14) in a lower half both arranged at the lateral surface of the straw (1). A sleeve element (20) can be arranged coaxially to and around the straw (1) to form a straw assembly (2). The sleeve element (20) is configured to close the first holes (13) in a first position and the second holes (14) in a second position. The straw assembly (2) can be arranged in a cup assembly (3). As the sleeve element (20) is also configured to float in a liquid the sleeve element (20) is moved through the force of buoyancy either to the first or the second position depending on the inclination of the cup assembly (3) with respect to the force of gravity. This provides a solution for any angle drinking.
