Abstract
A reusable, spill-proof lid for a drinking vessel. The lid has a cap member that is selectively moveable between a seated position to form an inner seal, and an unseated position that forms a gap that facilitates drinking of liquid contents from the drinking vessel. The lid is particularly moveable from the seated position to the unseated position via a downwardly directed force applied by the upper lip of a user.
Claims17
A lid for a drinking vessel, the lid comprising:
- a seal member for receipt by the drinking vessel, the seal member being configured to form an outer seal to seal liquid contents contained in the drinking vessel, the sealing member having an interior step, at least one sealing ring, and a tension web;
- and
- a cap member operatively connected to the seal member for selective movement between a seated position to form an inner seal to seal the liquid contents and at least a partially unseated position via a force applied in a downward direction against the cap member to create a gap that facilitates flow of the liquid contents through the lid and from the drinking vessel, the cap member having a support member, an outer rim, and an interior shelf.
A lid for a drinking vessel, the lid comprising:
- a seal member for receipt by the drinking vessel, the seal member including an interior step, a tension web, and a plurality of sealing rings configured to form an outer seal to seal liquid contents contained in the drinking vessel;
- and
- a cap member operatively connected to the seal member, the cap member including:
- an interior shelf configured to make 360-degree direct contact with the interior step to form an inner seal to seal liquid contents contained in the drinking vessel in a seated position of the cap member to define the inner seal, and
- an outer rim configured to selectively move the cap member to at least a partially unseated position upon receipt of a downwardly directed force on the outer rim, to thereby create a gap between the interior shelf and the interior step that facilitates flow of the liquid contents through the lid and from the drinking vessel.
