A straw composed of first and second straw body elements that are pivotally coupled at a first longitudinal end of the straw is described. The straw body elements can be pivoted between a stable drinking position in which a longitudinally sealed channel is formed between the straw body elements, and a splayed position suitable for washing internal channel wall portions of the straw body elements.

A foldable drinking straw made of paper developing along a longitudinal axis, and having a flexible shaped portion configured to allow a folding, one over the other, of two adjacent portions of the straw. The flexible shaped portion is defined by a plurality of depressions, disposed in succession along the longitudinal axis, and each made on a limited circumferential portion of the circular section of the straw.

This present invention relates to a flavor dispensing drinking straw device designed to retain and dispense an appropriate amount of flavoring, syrup and/or medicine into a beverage as per the desires of the users. The device comprises a topper having an internal cavity that holds a predefined amount of flavoring, syrup and/or medicine that the user can dispense through a spiral straw by simply and gently squeezing the topper, wherein the user can then consume the flavored or medicated beverage through a second tubular straw in a traditional manner. The uniquely designed straw device is both environmentally safe and reusable. Additionally, the topper can be refilled with the flavor, once the stored flavor is exhausted. The flavor infusing straw offers a more enjoyable and delicious drinking experience, and can be used with a variety of beverage containers.

A drinking device comprises a drinking straw with an inner flow channel and a drinking end and an aroma container connected with the drinking straw for adding an aroma substance to an air flow flowing out of the aroma container. The aroma container comprises at least one air outlet opening which is in flow connection either with at least one aroma inlet opening into the inner flow channel or with an aroma channel extending up to the drinking end of the drinking straw. The aroma container is able to be coupled with the drinking straw in such a way that, when applying a negative pressure at the drinking end or at a mouthpiece connected with the drinking end, the air flow exits from the aroma container through the air outlet opening. The aroma container comprises an aroma chamber containing a carrier substance for an aroma substance, wherein the carrier substance preferably has a specific flow resistance of less than 500 Pa.Math.s/m.
