SOLUTION: The straw for drinks consists of an inner straw 1 and an outer straw 2, the inner straw 1 is housed in the outer straw 2. The inner straw 1 is pulled out of the outer straw 2 and extended.

At a position near the drinking opening 8 of the outer straw 2, the bellows portion 7 is similarly provided. COPYRIGHT: (C)2009,JPO&INPIT
