Abstract
A drinking vessel having a cup with a removable lid having an inlet-outlet opening which receives an elastic straw-vent assembly having a flexible tubular straw and an air passageway forming a vent opening. A cover movably mounted on top of the lid, shiftable between a closed and an open position, with an inward surface of the cover forming fluid tight seal with the vent opening when the cover is in the closed position. In the closed position the cover engages the straw, folding the straw against the lid to seal the straw passageway, and in the open position, the straw fluid passageway and the vent opening are unobstructed by the cover. A removeable elastic straw-vent assembly is also disclosed having a tab to be grasped by the user for easy removal for cleaning.
Claims15
A drinking vessel, comprising:
- a cup having an open mouth and an internal cavity;
- a removable lid attachable to the cup mouth, the lid having an inlet-outlet opening;
- an elastic straw-vent assembly having an elastic body sealingly engaging the inlet-outlet opening, a flexible tubular straw having a fluid passageway extending through the elastic body, and an air passageway forming a vent opening;
- and
- a cover movably mounted on top of the lid, shiftable between a closed position and an open position, with an inward surface of the cover, when in the closed position, forming a fluid tight seal with the vent opening and pinching the flexible tubular straw against the lid closing the fluid passageway;
- wherein, when opening the cover from the closed position, the cover disengages the vent opening before un-pinching and unfolding the straw,
- wherein, when the cover is in the opening position, with straw available to drink from, the vent opening is unobstructed by the cover.
A drinking vessel, comprising:
- a cup having an open mouth and an internal cavity;
- a removable lid attachable to the cup mouth, the lid having an inlet-outlet opening and an air vent opening;
- an elastic straw assembly having an elastic body sealingly engaging the inlet-outlet opening, a vent membrane having a slit cooperating with the air vent opening in the removable lid, a flexible tubular straw having a fluid passageway extending through the elastic body and a straw membrane provided within the fluid passageway within a slit therein to resist the flow of liquid;
- and
- a cover movably mounted on top of the lid, shiftable between a closed position and an open position, with an elastic projection on an inward surface of the cover forming fluid tight seal with the vent opening when the cover is in the closed position;
- wherein, in the closed position the cover engages the straw, folding the straw against the lid to seal the straw passageway, and in the open position, the straw fluid passageway and the air vent opening are unobstructed by the cover;
- wherein the air vent further comprises an annular vent ring which surrounds the vent operating which sealingly engages a projection formed on an internal surface of the cover when the cover is in the closed position providing a detent mechanism holding the cover in the closed position.
