It will also be understood that different embodiments may include various combinations of these parts, components, features and aspects depending, for example, upon the intended use of the lids and containers.
(23) As shown in
(24) A lid 12 may be attached to the container 10. The lid may include an upper surface 14 and an outer wall or skirt 16. In some embodiments, the lid 12 may be selectively attached to the container 10. For example, the lid 12 may be connected to the container 10 by a threaded connection. In particular, the skirt 16 of the lid 12 may include one or more internal threads and an upper portion 18 of the container may include one or more external threads 20, as illustrated in
(25) The container 10 may include a body 22 with a base or lower portion 24 and a central portion 26. It will be appreciated by one of ordinary skill in the art, after reviewing this disclosure, that the container 10 may have different shapes, sizes, configurations, arrangements, features and aspects. Exemplary embodiments of containers, and various shapes, sizes, configurations, arrangements, features and aspects, that may be used with the container 10 are shown in U.S. Pat. Nos. D510,235; D677,121; D697,798; D727,097; 8,695,830; and 8,833,586; and U.S. Patent Publication Nos. 2014-0091086 and 2014-0360908; each of which is incorporated by reference in its entirety.
(26) As shown in
(27) The lid may also include a fluid pathway 34 that facilitates fluid flow. The fluid pathway 34 may be a structure with a passageway, such as an interior passageway, and fluid may flow through the passageway. The fluid pathway 34 may be an elongated structure with a generally tubular or cylinder-shaped configuration. At least a portion of the fluid pathway 34 may be disposed in the fluid-flow member 28 and movement of the fluid-flow member may move at least a portion of the fluid pathway. A first end of the fluid pathway 34 may form at least a portion of a mouthpiece to facilitate drinking from the container 10 and a second end of the fluid pathway may be connected to or in fluid communication with an opening in the lid 12. The second end of the fluid pathway 34 may also be connected to or in fluid communication with a straw, as discussed in more detail below.
(28) When the fluid-flow member 28, the connecting member 30, and the activator 32 are in the closed position, the container 10 may be in a closed position, as shown in
(29) The activator 32 may include an extension 36 that extends generally upwardly and/or outwardly from an upper surface of the activator. The extension 36 may form at least a portion of a handle or carrying member, and the carrying member may have a loop-shaped configuration as shown in
(30) The activator 32 may be pivotally connected to the connecting member 30. For example, as shown in
(31) The activator 32 may also be pivotally connected to the lid 12. For example, the activator 32 may include an end 44, shown in
(32) The fluid-flow member 28 may be pivotally connected to the connecting member 30. For example, the fluid-flow member 28 may be pivotally connected to the side walls 38 of the connecting member 30. In particular, as shown in
(33) The fluid-flow member 28 may be pivotally connected to the lid 12. For example, the fluid-flow member 28 may include one or more protrusions 56, shown in
(34) The fluid-flow member 28, the connecting member 30, and the activator 32 may be interconnected, and the movement of the activator may move the connecting member and the fluid-flow member. For example, movement of the activator 32 from the closed position to the open position may cause the connecting member 30 and the fluid-flow member 28 to move from the closed positions to the open positions. Similarly, movement of the activator 32 from the open position to the closed position may move the connecting member 30 and the fluid-flow member 28 from the open positions to the closed positions.
(35) In greater detail, the protrusions 40 of the connecting member 30 and the receiving portions 42 of the activator 32 may form a pivotal connection. The protrusions 48 of the activator 32 and the receiving portions 50 of the lid 12 may form another pivotal connection. Thus, the activator 32 may be pivotally connected to both the lid 12 and the connecting member 30.
(36) The protrusions 52 of the connecting member 30 and the receiving portions 54 of the fluid-flow member 28 may form still another pivotal connection. The protrusions 56 of the fluid-flow member 28 and the receiving portions 58 of the lid 12 may form a further pivotal connection. Therefore, the fluid-flow member 28 may be pivotally connected to both the lid 12 and the connecting member 30. In this exemplary embodiment, the activator 32 may be pivotally connected to the lid 12 by a first pivotal connection; the activator may be pivotally connected to the connecting member 30 by a second pivotal connection; the fluid-flow member 28 may be pivotally connected to the lid by a third pivotal connection; and the fluid-flow member may be pivotally connected to the connecting member. Accordingly, the lid 12, the activator 32, the connecting member 30, and the fluid-flow member 28 may be connected at four pivot points. When the activator 32, the connecting member 30, and the fluid-flow member 28 are in the closed position, the positioning or geometry of the four pivot points may provide an over-center latch, linkage or mechanism that creates a pressure or a force between the activator and the fluid-flow member that helps keep or maintain the lid 12 in the closed position. In this exemplary configuration, the activator 32 must be acted upon to move to the open position. An exemplary over-center latching assembly is shown in U.S. Pat. No. 8,844,746, which is included by reference in its entirety.
(37) As mentioned above, the fluid-flow member 28, the connecting member 30, and the activator 32 may be moved between the open and closed positions by applying a force to the activator. In particular, a user may apply a force to the extension 36 of the activator 32 to move the fluid-flow member 28, the connecting member 30, and the activator 32 between the open and closed positions. In further detail, the user may apply an opening force to a first portion of the extension 36 to move the activator 32 from the closed position to the open position. The user may also apply a closing force to a second portion of the extension 36 to move the activator 32 from the open position to the closed position.
(38) Significantly, the user may only touch the extension 36 of the activator 32 to open and close the lid 12 and/or control fluid flow to allow a user to drink fluid from the container 10. Because the user may only touch the extension 36 to open and close the lid 12, that may facilitate use of the lid when a user's hands may be unclean or unwashed, the user is wearing gloves, the user's hands are sweaty or perspiring, and the like. Importantly, this may facilitate use of the lid 12 in environments such as exercising, bodybuilding, climbing, gardening, construction, repairing, cleaning, wearing gloves, and the like where it may be desirable not to touch any surfaces that may touch the user's mouth.
(39) When the activator 32 is in the closed position, the extension 36 may be disposed in a generally upward direction. When the activator 32 is in the open position, the extension 36 may be disposed in a generally downward direction and/or may contact a portion of the lid 12 such as the upper surface 14 of the lid and/or an outer edge of the skirt 16 of the lid 12.
(40) As shown in
(41) When the fluid-flow member 28 is in the closed position, a portion of the fluid pathway 34 may be disposed generally parallel to the body 62 of the connecting member 30. In greater detail, an end or upper portion 64 of the fluid pathway 34, such as a mouthpiece, may be disposed generally parallel to the upper surface 14 of the lid 12 and at least a portion of the mouthpiece may be disposed beneath a portion of the activator 32 when the lid is closed. This may help protect the mouthpiece 64 from damage and/or from becoming dirty or contaminated.
(42) As shown in
(43) The lower end 70 of the fluid pathway 34 may be coupled, connected, aligned and/or in fluid communication with an aperture 72 in the body 74 of the lid 12, shown in
(44) In some embodiments, a straw 76 may be at least partially disposed in the container 10 and the straw may be coupled to the lower end 70 of the fluid pathway 34 and/or the aperture 72 in the lid 12 in any suitable manner such as a friction fit, interference fit, snap fit, fasteners, clips, and the like. For example, a diameter of the straw 76 may be larger or smaller than a diameter of the lower end 70 of the fluid pathway 34 and/or the aperture 72 in the lid, and that may allow the straw to be connected to the fluid pathway or aperture by a friction or interference fit. The straw 76 and the fluid pathway 34 may provide a fluid passageway that may allow fluid to flow from the container 10, through the fluid pathway, and to the mouthpiece 64.
(45) When the fluid-flow member 28 is in the open position, the aperture 60 in the fluid-flow member may be generally aligned with the aperture 72 in the lid 12 and the flexible portion 68 of the fluid pathway 34 may be disposed in a generally straight or linear configuration. This configuration may allow fluid to flow from the container 10 through the fluid pathway 34. On the other hand, when the fluid-flow member 28 is in the closed position, the aperture 60 in the fluid-flow member may be not aligned with the aperture 72 in the lid 12 and the flexible portion 68 of the fluid pathway 34 may be disposed in an angled position of at least 60, 70, 80, 90 or more. In this configuration, the flexible portion 68 of the fluid pathway 34 may be angled or bent to pinch or close the fluid passageway, which may prevent fluid flow through the fluid passageway.
(46) In greater detail, when the connecting member 30 and the activator 32 move between the open and closed positions, the flexible portion 68 of the fluid pathway 34 may be configured to bend and/or straighten. For instance, when the fluid-flow member 28, the connecting member 30, and the activator 32 move from the open position to the closed position, the flexible portion 68 of the fluid pathway 34 may be at an angle, such as, for example, approximately 60, 70, 80, 90, or more. Alternatively, when the fluid-flow member 28, the connect member 30, and the activator 32 move from the closed position to the open position, the flexible portion 68 of the fluid pathway 34 may be at least substantially straightened so that the flexible portion is bent at no more than an angle of about 30, 20, 10, or less.
(47) When the fluid-flow member 28, the connecting member 30, and the activator 32 are in the closed position, the connecting member may be configured to pinch or otherwise close a portion of the flexible portion 68 to prevent the fluid from flowing through the flexible portion of the fluid pathway 34. When the fluid-flow member 28, the connecting member 30, and the activator 32 are in the open position, the connecting member may not pinch or close the flexible portion 68 and this may allow fluid to flow through the fluid pathway 34.
(48) In some embodiments, the bending of the flexible portion 68 of the fluid pathway 34 may prevent fluid flow through the fluid pathway. In other embodiments, the connecting member 30 may pinch or close a portion of the fluid pathway 34 to prevent fluid flow through the fluid pathway. If desired, the bending of the flexible portion 68 of the fluid pathway 34 and/or the movement of the connecting member 30 may independently and/or in combination close a portion of the fluid pathway 34 to prevent fluid flow through the fluid pathway.
(49) In some embodiments, the lid 12 may include an opening 80, as shown in
(50) As shown in
(51) In some embodiments, the container 10 may include a gasket 84, which may help create a fluid-tight seal between the lid 12 and the body 22 of the container 10. An exemplary gasket 84 is shown in
(52) In some embodiments, a locking mechanism may be used to lock at least a portion of the lid 12 in the closed position. For example, the locking mechanism may including a locking member 86 and the locking member 86 may lock the activator 32, the connecting member 30 and/or the fluid-flow member 28 in the closed position. The locking member 86 may have to be released or unlocked before the activator 32, the connecting member 30 and/or the fluid-flow member 28 can be moved from the closed to the open position.
(53) In greater detail, as shown in
(54) When it is desired to open the lid 12, a force may be applied to the extension 36. In particular, a generally downward and/or rearward force may be applied to a first portion of the extension 36 and that may cause the activator 32 to move from a closed position to an open position. The movement of the activator 32 may cause the connecting member 30 and/or the fluid-flow member 28 to move from closed to open positions. Advantageously, a user may drink from the container 10 when the lid 12 is in the open position. When it is desired to close the lid 12, a generally upward and/or forward force on a second portion of the extension 36 may cause the activator 32 to move from the open position to the closed position. The movement of the activator 32 from the open to the closed position may cause the connecting member 30 and/or the fluid-flow member 28 to move from open to closed positions. When the fluid-flow member 28 is in the closed position, the activator 32 may cover at least a portion of the flow-flow member such as a mouthpiece. Thus, the activator 32 may help protect the mouthpiece from damage, dirt, and the like when the flow-flow member 28 and activator 32 are in the closed position.
(55) In an embodiment with a locking mechanism, the locking member 86 may be used to maintain and/or secure the lid 12 in the closed position. In this exemplary embodiment, when it is desired to open the lid 12, a force may be applied to the locking member 86 and the locking member may move from the locked to the unlocked position. When the locking member 86 is unlocked, the activator 32 may be moved from the closed to the open position and this movement may cause the connecting member 30 and/or the fluid-flow member 28 to move from the closed to open positions. If desired, the locking member 86 may be used to maintain and/or secure the lid 12 in the open position. When the activator 32 is moved into the closed position, the locking member 86 preferably automatically locks the activator in the closed position. The locking member 86 may be automatically and/or manually locked and/or unlocked depending, for example, upon the intended use of the container 10 and/or lid 12.
(56) After reviewing this disclosure, one of ordinary skill in the art will understand that the fluid-flow member 28, the connecting member 30, the activator 32, and the fluid pathway 34 may have other suitable shapes, shapes, configurations and arrangements depending, for example, upon the size and shape of the container 10 and/or the lid 12.
(57) The container 10 and the lid 12 may be constructed from durable, long-lasting materials. The container 10 and the lid 12 may also be constructed from materials that may be reused and/or recycled. The container 10 and the lid 12 may, for example, be constructed from a relatively rigid, durable, and high-strength materials such as plastic, polymers, and composites. In particular, the container 10 and the lid 12 may be constructed from materials such as polyethylene, copolyester, or other materials with similar properties and/or characteristics. In view of this disclosure, one of ordinary skill in the art will appreciate that the container 10 and the lid 12 may be constructed from various materials with desired properties such as different types of plastics, glass, metal, composites, and the like. Additionally, the container 10 and the lid 12 may be constructed from at least partially transparent or translucent materials, which may allow the user to see the type and/or amount of fluids in the container.
(58) Advantageously, the lid 12 may be simple to use and operate. In addition, the lid 12 may be quickly and easily assembled, cleaned, and disassembled. Further, the lid 12 may be efficiently manufactured, easily repaired, and/or conveniently replaced.
(59) The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects as only illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims, rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
