Definitions

  • the present disclosure relates to a lid for a kitchenware vessel, and more particularly, to a lid capable of selectively forming a fluid-tight seal with a kitchenware vessel.
  • Kitchenware vessels and lids are generally known in the relevant art.
  • Some known vessel-and-lid combinations include locking features for removably securing a lid to a vessel, including some vessel-and-lid combinations that include features for selectively enabling a seal between an interior and an exterior of the vessel.
  • these known lids or vessel-and-lid combinations include superfluous moving parts, adding complexity, weight and manufacturing costs.
  • these known lids require a user to undertake multiple steps to secure and release the lid from the vessel and selectively enable a seal between the interior and exterior of the vessel.
  • the accessories or integrated features available on known lids and vessel-and-lid combinations do not adequately address the above-mentioned issues. Accordingly, there is a need for a lid that forms a fluid-tight seal when a locking tab selectively secures the lid to a vessel, and for a lid that incorporates sealing features with a movable locking mechanism.
  • a removable lid for selectively sealing a storage vessel having a base and a continuous sidewall.
  • the removable lid comprises a main body having a bottom surface and a top surface and a tab movably secured to the main body.
  • the tab is selectively movable between a first position and a second position.
  • a gasket is secured to the bottom surface of the main body of the lid, and a vent is formed in the gasket.
  • the vent includes an aperture extending from an outer gasket side to an inner gasket side.
  • the vent also includes a vent seal.
  • a sealing protrusion is disposed on the tab.

  • a tab is movably secured to the main body such that the tab is selectively movable between a first position and a second position.
  • a gasket is secured to the bottom surface.
  • a channel is disposed on a lower surface of the gasket, and the gasket is selectively compressible between a relatively compressed state and a relatively uncompressed state. The channel allows a passage of fluid across the gasket when the gasket is in the relatively uncompressed state and the gasket forms a generally fluid-tight seal across the gasket when the gasket is in the relatively compressed state.
  • a storage container assembly includes a storage vessel having a base and a continuous sidewall and a removable lid.

  • the gasket 72 can be formed from a polymer, rubber, thermoplastic elastomer material or any other suitable material.
  • the gasket 72 can be attached to the lower side 22 of the lid 14 through a variety of mechanical or chemical attachment technologies including, but not limited to, adhesives, interference fits, mechanical fasteners and other relative geometric arrangements of the gasket 72 and lid 14.
  • a gasket channel 76 is, in some implementations, formed on the lower side 22 of the lid 14.
  • the gasket channel 76 aids in the positioning and securement of the gasket 72 on the lower side 22, and includes an inner gasket guide 80 and an outer gasket guide 82.

  • An inner gasket guide recess 90 visible in FIG. 3, is disposed on the inner gasket guide 80 and will be described below in greater detail.
  • the gasket 72 includes a vent 94 allowing a fluid or gaseous exchange between the interior and an exterior of the vessel 32 when the lid 14 is properly placed on the vessel 32.
  • the vent 94 includes an aperture 98 that passes through the gasket 72 from an outer gasket side 102 to an inner gasket side 106.
  • a sealing surface 110 is formed on the gasket 72 at an end of the aperture 98 or the vent 94.
  • the sealing surface 110 is formed on the outer gasket side 102.
  • the sealing surface 1 (e.g. a 'bell mouth"), forms a raised lip surface that protrudes outwardly from the gasket 72.
  • a sealing surface support 116 is also formed on the outer gasket side 102 and structurally supports the formation and functionalities of the sealing surface 110 described below.
  • the inner gasket guide recess 90 is disposed on the inner gasket guide 80 and is substantially aligned with the aperture 98 when the gasket 72 is disposed in the gasket channel 76.
  • the inner gasket guide recess 90 enables the inner gasket guide 80 to retain and position the gasket 72 in the gasket channel 76 and simultaneously allows fluid to flow through the aperture 98 without causing a fluid flow blockage.
  • FIGS. 4 and 5 illustrate a sealing protrusion 120 formed on the tab 60.
  • the sealing protrusion 120 extends from the tab 60 and terminates at a face 124 formed on a distal end 128 of the sealing protrusion.
  • the sealing protrusion 120 is, in some implementations, integrally formed with the tab 60 such that a movement of the tab 60 relative to the lid 14 and gasket 72 produces a corresponding movement of the sealing protrusion 120 relative to the lid 14 and gasket 72.
  • the face 124 is formed at an angle a from a side surface 129 of the sealing protrusion 120. In one preferred embodiment, the angle a is approximately 120 degrees.
  • FIG. 6 shows the tab 60 in a first position 150.
  • the vent 94 is closed such that a generally fluid-tight seal is formed at or near the aperture 98. It will be understood that a generally fluid-tight seal is achieved when the flow of fluid across the gasket 72 is substantially retarded. Accordingly, in this configuration, fluids and gasses are substantially prevented from flowing through the aperture 98 between the inner and outer sides of gasket 102, 106, and thus from an interior of the vessel 32 to an exterior of the vessel 32.
  • the sealing protrusion 120 seals the aperture 98 when the tab
  • the sealing protrusion 120 is moved in conjunction with a movement of the tab 60, the face 124 is brought towards the sealing surface 1 10 with a corresponding tab 60 movement towards the first position 150.

  • the face 124 may further press into the sealing surface 110 such that the face 124 compresses the sealing surface 110.
  • the tab securement protrusion 68 engages with a portion of the sidewall lip 52 to removably secure the lid 14 to the vessel 32.
  • the engagement of the tab securement protrusion 68 with the sidewall lip 52 also draws the lid 14 closer to the vessel 32 and/or compresses the gasket 72 against the sidewall lip 52 or peripheral edge 44 to form a generally fluid-tight seal between the gasket 72 and the sidewall lip 52 or peripheral edge 44.
  • the tab 60 being arranged in the first position 150 causes the sealing protrusion 120 to form a generally fluid-tight seal through the aperture 98.
  • the first position 150 corresponds to a releasable engagement between the lid 14 and the vessel 32, and also to a generally fluid tight-seal being formed through the aperture by the sealing protrusion 120.
  • the second position 160 corresponds to a lack of a securement between the lid 14 and the vessel 32 caused by the tab securement protrusion 68 and sidewall lip 52, and also to a lack of a generally fluid tight-seal being formed through the aperture by the sealing protrusion 120.
