A storage container assembly includes a container having an opening and a lid for covering the opening. The lid includes a top lid, a button, a cam, a base, a lower plate and a gasket. The top lid defines an upper surface of the lid. The button is moveable in a first axial direction with respect to the top lid between a projected position in which a top surface of the button is offset from the upper surface of the lid and a depressed position in which the top surface of the button is nearer to the upper surface of the lid as compared to the projected position. The cam is configured to cooperate with the button such that the button maintains the depressed position when moved from the projected position to the depressed position, and the button remains in the depressed position until pressed again while in the depressed position. The base is connected with the top lid. The cam is positioned between the button and the base. The lower plate is connected with the top lid. The gasket is moveable between a contracted state and an expanded state in response to alternate actuations of the button, and the gasket is interposed between the lower plate and the top lid.
A method for assembling a lid includes placing a cam on a base and placing a web on the base. The web includes a hub, a plurality of arms, a plurality of gasket pushers and a plurality of tensile connector elements. Each arm is connected with the hub and associated with a respective gasket pusher. Each tensile connector element interconnects adjacent gasket pushers. The method further includes connecting a button with the cam, placing a top lid on the base and connecting the base with the top lid. The top lid includes a button opening receiving the button. The method also includes attaching a gasket to the base and attaching a lower plate to at least one of the base and the gasket.
The button 30 is shown as generally circular in configuration, but the button could take other configurations such as square, rectangular, or other polygonal configurations. The button 30 includes an upper section 50 defining a top surface 52, which is the surface commonly pushed by an operator to move the button 30. The top surface 52 is generally planar in the illustrated embodiment and is typically horizontally oriented when the container 12 is resting on a horizontal surface in typical use. The button 30 includes a peripheral skirt 54 that extends downwardly from a periphery of the upper section 50. The peripheral skirt 54 is generally annular, or cylindrical, in configuration and is vertical in the illustrated embodiment when the container 12 is resting on a horizontal surface in typical use. Tabs 56 (four of which are shown in the illustrated embodiment) extend radially outwardly from a lower free end of the peripheral skirt 54. The tabs 56 facilitate connecting the button 30 with the top lid 32. With reference to
The top lid 32 includes a generally horizontally disposed upper section 70 that defines an upper surface 72 of the lid 14. A portion of the upper surface 72 immediately surrounding a button hole 74 is generally planar in the illustrated embodiment and is typically horizontally oriented when the container 12 is resting on a horizontal support surface, e.g. a table, and the lid 14 is covering the upper opening 22 (
The top lid 32 also includes a vertically oriented peripheral skirt 86 that depends downwardly from a periphery of the upper section 70. The peripheral skirt 86 generally matches the configuration of the side wall 16 of the container 12. An internal vertical wall 88 depends downwardly from the upper section 70 and is offset inwardly from the peripheral skirt 86. The internal vertical wall 88 is the same shape as the peripheral skirt 86, but is smaller. Ribs 90, which cooperate with the web 34, extend downwardly from the upper section 70. A channel 92 is formed between the peripheral skirt 86 and the internal vertical wall 88. At least a portion of the gasket 40 is received in this channel 92.

The hub 100 includes a central opening 114 that can receive the barb 60 on the button 30. The hub 100 includes ratchet teeth 116 (
The longer arms 102 extend outwardly from a lower end of the hub 100 and connect the hub 100 with the respective corner gasket pushers 106 located in the corners of the web 34. Each longer arm 102 includes a first (proximal) hinge section 120 connecting the longer arm 102 with the hub 100 and second (distal) hinge section 122 connecting a respective corner gasket pusher 106 with the longer arm 102. Each hinge section 120 and 122 operates as a flexure. Each hinge section 120 and 122 has a thickness that is smaller as compared to the section of each longer arm 102 between the hinge sections.
The shorter arms 104 also extend outwardly from a lower end of the hub 100. Each shorter arm 104 is associated with a respective central gasket pusher 108 located between respective corner gasket pushers 106 of the web 34. Each shorter arm 104 includes a proximal hinge section 130 connecting the shorter arm 104 with the hub 100 and a distal section 132 that is associated with and selectively contacts a respective central gasket pusher 108. The proximal hinge section 130 operates as a flexure. As the hub 100 is moved downward in the direction of arrow 44 (
Each gasket pusher 106, 108 includes a respective gasket contact surface 136, 138 that contacts the gasket 40. Each gasket contact surface 136 on the corner gasket pushers 106 is generally L-shaped and each gasket contact surface 138 on the central gasket pushers 108 is linear in plan view. Each corner gasket pusher 106 can include an opening 140 to provide a locating feature for the corner gasket pusher 106 and the web 34, and also to limit movement of the corner gasket pusher 106 (see also
The tensile connector elements 110 interconnect adjacent gasket pushers 106, 108. In the illustrated embodiment, eight gasket pushers 106, 108 are provided and interconnected by eight tensile connector elements 110, and the tensile connector elements 110 are each ring-shaped. When the gasket pushers 106, 108 are in the extended position, the tensile connector elements 110 are tension urging the gasket pushers 106, 108 back toward the retracted position. The cam 36, however, maintains the gasket pushers 106, 108 in the extended position until the button 30 is pushed again after the button 30 is in the depressed position.
The cam 36 includes a cylindrical body 144 having vertical channels 146 and ratchet teeth 148. The cam 36 connects with the button 30 through the barb 60 by being inserted through the central opening 114 in the hub 100 and through an opening 152 in the cam 36. The cam 36 rotates with respect to the button 30 on the barb 60. The gasket 40 acts against the web 34 to bias the button 30 toward the projected position (
The base 38 is formed of a plate 160 having an upper surface 162 facing toward the top lid 32 and a lower surface 164 (
The base 38 further includes a central annular boss 174 having inwardly extending upper projections 176 that do not extend vertically all the way to the upper surface 162. The cam 36 is received in the central annular boss 174 and the vertical channels 146 cooperate with the projections 176 so that the button 30 is stable in an projected position in which the top surface 52 of the button is offset from the upper surface 72 of the lid 14 (shown in

The gasket 40 includes a gasket base 190, which is substantially planar in the illustrated embodiment. A lower side wall 192 extends upwardly from a periphery of the gasket base 190. The lower side wall 192 transitions into an upper side wall 194 through a shoulder 196; the upper side wall 194 being a larger rectangle than the lower side wall 192. The upper side wall 194 terminates at an upper free edge 198, which is received in the channel 92 formed between the peripheral skirt 86 and the internal vertical wall 88 on the top lid 32 when the lid 14 is finally assembled. Indentations 202 are provided at the corners of the upper free edge 198 to facilitate removal of the gasket 40 from the top lid 32. The gasket 40 also includes a sealing lip 204 that extends outwardly from the lower side wall 192 and towards the upper side wall 194. The sealing lip 204 is pressed against the inner surface 24 of the container 12 when the gasket 40 is in the expanded state.
The gasket 40 also includes a cylindrical wall 206 that depends downwardly from the gasket base 190. A lower circular wall 208 extends from a lower end of the cylindrical wall 206 to define a boss recess 212 that receives the boss 182 to attach the gasket 40 with the base 38. The gasket 40 covers an entirety of the lower surface 164 of the base 38 in the illustrated embodiment. The gasket 40 also includes an internal wall 216 that extends upwardly from the gasket base 190. A top wall 218 extends from an upper end of the internal wall 216 to define a grip recess 220 together with the internal wall 216. A gripping member 222 is positioned in the grip recess 220. A user can grip the gripping member 222 to remove the gasket 40 from the base 38 and the top lid 32.
The lower plate 42 includes a base wall 230 and a peripheral wall 232 extending upwardly from a periphery of the base wall 230. The lower plate 42 also includes a lower plate cylindrical wall 234 that depends downwardly from the base wall 230. The lower plate cylindrical wall 234 has a diameter slightly larger than a diameter of the lower circular wall 208. A lower plate circular wall 236 extends from a lower end of the lower plate cylindrical wall 234 to define a boss cavity 238 that receives the boss 182 and a portion of the gasket 40 surrounding the boss 182. The lower plate 42 can provide a cosmetic function and cover an entirety of the gasket base 190. The lower plate 42 is made from a smooth rigid plastic material and the gasket 40 is made from a resilient material such as silicone. The lower plate 42 can cover the gasket 40 to preclude items stored in the container 12 from sticking to the gasket 40. The lower plate 42 connects with the top lid 32 through the gasket 40 and the base 38 in a manner such that the lower plate 42 does not move with respect to the top lid 32 when the button 30 is pressed or moved with respect to the top lid 32. Instead, only the gasket 40 moves outwardly with respect to the top lid 32 and the lower plate 42. The lower plate cylindrical wall 234 can also be appropriately shaped to allow for the connection of utensils (e.g., spoons, scoopers) and other tools that can be stored in the container 12 along with other contents of the container 12.
The button 30 is moveable in a first axial direction (parallel with arrow 44 in
The lid 14 can be assembled in an easy manner. A method for assembling the lid 14 includes placing the cam 36 on the base 38, and placing the web 34 on the base 38. The method further includes connecting the button 30 with the cam 36, placing the top lid 32 on the base 38, and connecting the base 38 with the top lid 32. The method further includes attaching the gasket 40 to the base 38 and attaching the lower plate 42 to at least one of the base 38 and the gasket 40. The boss 182 on the base 38 can be inserted into the boss cavity 238 in the lower plate 42 with the gasket 40 attached to the base 38. The boss 182 on the base 38 can be inserted into the boss recess 212 in the gasket 40 prior to inserting the boss 182 into the boss cavity 238.
The method for assembling the lid 14 can allow for the easy stacking of components on top of one another, which facilitates the assembly process. The order of the steps described above need not be performed in the exact order described.
