Container lid with integral stopper

Claim 2

A lid for a container for holding a liquid, the container having an upwardly facing, generally planar opening bounded by an edge, the lid comprising: a circular rim portion including means for sealingly engaging the container opening, the rim portion defining a first plane; a cover portion within the rim portion to cover the container opening, the cover portion having an outer and inner surface, the outer surface defining a second plane situated below and at an angle to the first plane, a first part of the outer surface being closer to a container bottom position than a second part of the outer surface; an opening formed in the first part of the cover portion and extending between the outer surface and the inner surface, whereby liquid which is exposed to the outer surface flows by gravity toward the first part of the outer surface and flows through the opening into the container; a support centrally situated in the planar cover portion between the first part and the second part of the upper surface, the support having an upper margin situated at least as high as the first plane; a closure member formed unitarily with the cover and configured to seal the cover opening; and hinge means for permitting the closure member to be pivoted between a position where the closure member is engaged in the cover opening and a position where the closure member is displaced from the cover opening.

Claim 3

The lid of a claim 1 further comprising a web portion situated between the closure member and the hinge means having a width comparable to the closure member overlying an area of the first part of the planar cover portion when the closure member is engaged in the cover opening.

Claim 4

A lid for a container having an upstanding side wall with an upper edge bordering a circular upwardly facing opening, the lid comprising: a circular rim portion defining a first plane and including means for engaging the upper edge of the container; a generally planar cover portion situated within the rim portion to completely cover the container opening when the lid is in place, the cover portion having an upper surface defining a second plane, the second plane being situated below and inclined with respect to the first plane such that a first part of the upper surface is farther from the upper edge than an opposite, second part of the upper surface, the planar cover portion having an opening in the first part of the upper surface through which liquid can be extracted from the container; a central protrusion extending upperwardly from the planar cover portion between the lower first portion and an opposite higher second portion, the support having an upper margin situated at least as high as the first plane; and a closure member sized and configured to seal the cover opening, and means for pivotally mounting the closure member to the support upper margin to permit the closure member to be provided from a position where the closure member is engaged in the cover opening to a position where the closure member is displaced from the cover opening.

Claim 5

A lid for a container having an upstanding side wall with an upper edge bordering a circular upwardly facing opening, the lid comprising: a circular rim portion defining a first plane and including means for engaging the upper edge of the container; a generally planar cover portion situated within the rim portion to completely cover the container opening when the lid is in place, the cover portion having an upper surface defining a second plane, the second plane being situated below and inclined with respect to the first plane such that a first part of the upper surface is farther from the upper edge than an opposite, second part of the upper surface, the planar cover portion having an opening in the first part of the upper surface through which liquid can be extracted from the container; a central protrusion extending upperwardly from the planar cover portion between the lower first portion and an opposite higher second portion, the support having an upper margin situated at least as high as the first plane; and a closure member sized and configured to seal the cover opening, and means for pivotally mounting the closure member to the support upper margin to permit the closure member to be provided from a position where the closure member is engaged in the cover opening to a position where the closure member is displaced from the cover opening.

Claim 6

The lid of claim 3 wherein the mounting means comprises a living hinge defining a line along an upper surface of the support member.

Claim 7

The lid of claim 3 wherein the closure member further comprises a tab for lifting the closure member upwardly away from the cover opening.

Claim 8

The lid of claim 5 further comprising locking means situated on the rim portion opposite the opening for engaging the tab of the closure when the closure in a fully open position.

Claim 9

The lid of claim 3 wherein the closure member is resealable in the cover opening.

Claim 10

A lid and a container, the container having an upstanding side wall with an upper, circular edge that borders an upwardly facing opening, the circular edge defining a first plane, the lid comprising: a circular rim portion that includes an inner wall and an attached outer wall, the inner wall and outer wall straddling the container edge, with the outer wall sealingly engaging an outer surface of the container side; a generally planar cover portion having an outer surface and an inner surface, the cover extending between and sealingly attached to the rim inner wall, the cover portion defining a second plane below the first plane and inclined with respect to the first plane such that the planar cover portion includes a lower first portion and an opposite higher second portion, the lower first portion of the cover including an opening; an upperwardly extending support centrally situated in the planar cover portion between the lower first portion and an opposite higher second portion, the support having an upper margin situated at least as high as the first plane; and a closure member formed unitarily with the cover and configured to seal the cover opening, and means for pivotally mounting the closure member to the support upper margin to permit the closure member to be pivoted between a position where the closure member is engaged in the cover opening and a position where the closure member is displaced from the cover opening.

Claim 11

A lid and a container, the container having an upstanding side wall with an upper, circular edge that borders an upwardly facing opening, the circular edge defining a first plane, the lid comprising: a circular rim portion that includes an inner wall and an attached outer wall, the inner wall and outer wall straddling the container edge, with the outer wall sealingly engaging an outer surface of the container side; a generally planar cover portion having an outer surface and an inner surface, the cover extending between and sealingly attached to the rim inner wall, the cover portion defining a second plane below the first plane and inclined with respect to the first plane such that the planar cover portion includes a lower first portion and an opposite higher second portion, the lower first portion of the cover including an opening; an upperwardly extending support centrally situated in the planar cover portion between the lower first portion and an opposite higher second portion, the support having an upper margin situated at least as high as the first plane; and a closure member formed unitarily with the cover and configured to seal the cover opening, and means for pivotally mounting the closure member to the support upper margin to permit the closure member to be pivoted between a position where the closure member is engaged in the cover opening and a position where the closure member is displaced from the cover opening.
