Drink container and leak proof plug lid for use therewith

A drink container, comprising:

• a container body having an inner body portion defining an interior fluid passageway with an upper end opening;
• and
• a lid sized to permit insertion into and removal from the fluid passageway through the upper end opening, the lid having:
• an upper member positioned within the fluid passageway;
• a lower member positioned within the fluid passageway in position below the upper member;
• a ring seal positioned between the upper member and the lower member, the ring seal being outwardly stretchable from an initial perimeter size to a sealing perimeter size larger than the initial perimeter size;
• and
• an actuator member movable to first and second operational positions, in response to the actuator member moving from the second operational position to the first operational position, the actuator member axially moves the upper and lower members together and in response the upper member stretches the ring seal outward from the initial perimeter size to the sealing perimeter size whereat the stretched ring seal is in fluid-tight sealing engagement with the inner body portion, and in response to the actuator member moving from the first operational position to the second operational position, the actuator member axially moves the upper and lower members apart and in response the upper member allows the outward stretched ring seal to move inward from the sealing perimeter size to the initial perimeter size whereat the ring seal is out of fluid-tight sealing engagement with the inner body portion.

A lid for use with a drink container body having an inner body portion defining an interior fluid passageway with an upper end opening, comprising:

• a ring seal having a central aperture and being positioned on and extending about the upper member, the ring seal being outwardly stretchable from an initial perimeter size to a sealing perimeter size larger than the initial perimeter size in response to the inwardly tapered portion of the upper member moving downward through the central aperture of the ring seal;
• and
• an actuator member movable to first and second operational positions, in response to the actuator member moving from the second operational position to the first operational position, the actuator member axially moves the upper member downward toward the lower members to progressively move larger perimeter portions of the inwardly tapered portion of the upper member into the central aperture of the ring seal and thereby outwardly stretch the ring seal from the initial perimeter size to the sealing perimeter size whereat the stretched ring seal is in fluid-tight sealing engagement with the inner body portion when the lid is positioned in the fluid passageway.

• an actuator member movable to first and second operational positions, as the actuator member is moved from the second operational position to the first operational position, the actuator member axially moves the upper and lower members together and in response the upper member stretches the ring seal outward to the sealing perimeter position whereat the stretched ring seal is in fluid-tight sealing engagement with the inner body portion when the lid is positioned in the fluid passageway, and as the actuator member is moved from the first operational position to the second operational position, the actuator member axially moves the upper and lower members apart and in response the upper member allows the outwardly stretched ring seal to move inward to the initial perimeter position whereat the ring seal is out of fluid-tight sealing engagement with the inner body portion when the lid is positioned in the fluid passageway.

A lid for use with a fluid container body having an inner body portion defining an interior fluid passageway with an upper end opening, comprising:

• a ring seal being outwardly stretchable from an initial perimeter position to a sealing perimeter position outward of the initial perimeter position;
• an actuator member movable between first and second operational positions;
• and
• stretching means for outwardly stretching the ring seal from the initial perimeter position whereat the ring seal is out of fluid-tight sealing engagement with the inner body portion when the lid is positioned in the fluid passageway to the sealing perimeter position whereat the stretched ring seal is in fluid-tight sealing engagement with the inner body portion when the lid is positioned in the fluid passageway, in response to the actuator moving from the second operational position to the first operational position.

A lid for use with a fluid container body having an inner body portion defining an interior fluid passageway with an upper end opening, comprising:
