Drinking cup assembly

摘要

There is a drinking cup assembly comprising an outer cup and an inner cup, the outer cup having a dispensing closure, the inner cup being removably attached to the outer cup. A space is located between the outer cup and the inner cup, can contain an item being insertable into this space. The dispensing closure has an aperture and is adapted to receive a flexible conduit straw and a rotatable lid to open and close the flexible conduit straw. The flexible conduit straw has a weighted lower end of a soft plastic or a material coated with a soft plastic. The outer cup and inner cup are each structured to receive a sealing lid to separately close the outer cup and/or the inner cup. The attachment of the lids may be by one of an interference fit or a threaded attachment. The closure has a recess adjacent to the aperture, the flexible conduit fitting within this recess upon the rotatable lid flexing the conduit to close the conduit. The outer cup has handles. The inner cup can be metallic such as an aluminum or stainless steel. The inner cup may also be a glass such as a Pyrex, or a plastic such as a polyester, or a polyolefin and can include a silicone. The drinking cup assembly has a combined gasket/valve combination to seal the closure to the outer cup and to equalize the pressure in the cups with the exterior. The flexible conduit straw has a plurality of segments, at least one of the segments having a surface with a cross-cut to prevent leakage.
