Abstract

Drinking cup for children having a closed lid with incorporated straw to minimize liquid spills and leaks. 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 the elastic straw-vent assembly further comprises a thin vent membrane within the air passageway having a slit which limits liquid from leaking out of the vessel when tipped; wherein the slit in the vent membrane opens in an outward flow direction at a pressure greater than the pressure exerted on the vent membrane when the sippy cup full of water is inverted; wherein the elastic straw-vent assembly has a mound shaped protrusion which extends about the vent opening, and the inner surface of the cover is provided with a projection which seals the vent opening closed when the cover is in the closed position further providing a detent mechanism holding the cover in the closed position.

Claims (9)

WHAT IS CLAIMED IS:
1. 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 the elastic straw-vent assembly further comprises a thin vent membrane within the air passageway having a slit which limits liquid from leaking out of the vessel when tipped; wherein the slit in the vent membrane opens in an outward flow direction at a pressure greater than the pressure exerted on the vent membrane when the sippy cup full of water is inverted; wherein the elastic straw-vent assembly has a mound shaped protrusion which extends about the vent opening, and the inner surface of the cover is provided with a projection which seals the vent opening closed when the cover is in the closed position further providing a detent mechanism holding the cover in the closed position.
2. The drinking vessel of claim 1, wherein the straw membrane has a convexly shaped inwardly projecting shape preventing the opening of the slit in an outward flow direction at when the vessel full of water is inverted with the straw extended. BBOX0103PCT
3. The drinking vessel of claim 1, wherein the elastic straw-vent assembly further comprises a thin vent membrane within the air passageway having a slit which limits liquid from leaking out of the vessel when tipped.
4. The drinking vessel of claim 3 wherein, when the cover is in the open position and the internal cavity is pressurized, the vent membrane opens at a pressure which is sufficiently low relative to an opening pressure of the straw membrane to prevent liquid from being displaced through the straw due to pressure in the internal cavity.
5. The drinking vessel of claim 1 wherein the cover is pivotably mounted by a pair of pins on the cover which project into matching bores in the lid, preferably the pins and their matching bores are of different diameters so that the cover only attaches to the lid in one orientation.
6. The drinking vessel of claim 1 wherein the elastic straw-vent assembly further comprises a pull tab extending inwardly into the vessel when installed on the lid which can be grasped by a user enabling the elastic straw-vent assembly to be detached from the lid.
7. The drinking vessel of claim 1 of, wherein the slit in the air passageway vent membrane of the elastic straw-vent assembly is normally closed and opens at a pressure of at least 6 inches of water.
8. The drinking vessel of claim 1, wherein the elastic body of the elastic straw- vent assembly is made of polymer having a durometer of Shore A 30-70.
9. The drinking vessel of claim 1, wherein, the inward surface of the cover is configured so that when opening the cover from the closed position, the cover unseals the vent opening before un-pinching and unfolding the straw.
