DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to FIGS. 1A and 1B, a stopper 10 is shown in connection with a beverage container 12 having a fill opening 14 that is closed by the stopper 10. The stopper 10 includes a rigid lanyard loop 16, with the lanyard loop 16 being shown in a stowed or undeployed position in FIG. 1A and in an unstowed or deployed position in FIG. 1B. While one preferred form of beverage container 12 is shown, it should be understood that the invention can be employed with any suitable beverage container having a fill opening that can be closed by a stopper to prevent or restrict leakage of the beverage from the container. This includes insulated and uninsulated beverage containers made from any of a variety of suitable materials, including metallic materials and plastic or composite materials. Because the details of the beverage container 12 are not critical to the invention, they will not be described further herein.
Turning now in more detail to the construction of the stopper 10, as best seen in FIGS. 2-6, the stopper includes a main body 18, a lid 22, and the rigid lanyard loop 16. The main body 18 is configured for releasable engagement with the opening of the beverage container 12 and includes a drinking port 24 (best seen in FIGS. 5C and 6) to allow a beverage to flow from the beverage container to the mouth of a user. The lid 22 is hinge mounted to the main body 18 for movement between a closed position (shown in FIGS. 1A, 1B, 2A, 2B, 3A, 3B, 4A, 4B, 5A and 5B) wherein the drinking port 24 is covered and an open position (shown in FIGS. 2C, 3C, 4C and 5C wherein the drinking port 24 is exposed for access by a user. The lanyard loop 16 is hinge mounted for movement relative to the lid 22 between the stowed position (shown in FIGS. 1A, 2A, 2C, 3A, 3C, 4A, 4C, 5A and 5C) wherein the lanyard loop 16 extends adjacent an upper surface 26 of the lid 22 and the deployed position (shown in FIGS. 1B, 2B, 3B, 4B and 5B) wherein the lanyard loop 16 extends away from the upper surface 28 with the lid 22 in the closed position. In this regard, preferably the upper surface 26 of the lid 22 is interrupted by a recess 28 (best seen in FIGS. 5A and 5B) that receives the lanyard loop 16 in the stowed position, with an upper surface 30 of the lanyard loop 16 being flush with the upper surface 26 of the lid 22.
With respect to the hinge mounting of the lid 22 and the lanyard loop 16, the main body 18 includes a pair of hinge knuckles 32 that carry a hinge pin 34 that defines a transversely extending hinge axis 36. The lanyard loop 16 includes a hinge knuckle 38 receiving the hinge pin 34 and located between the hinge knuckles 32 of the main body 18. The lid 22 includes a pair of hinge knuckles 40 receiving the hinge pin 34 and spaced on opposite sides of the hinge knuckles 32 that face away from the lanyard loop knuckle 38. Preferably, a pair of resilient members 42 are sandwiched between the hinge knuckles 40 of the lid 22 and the hinge knuckles 32 of the main body 18. In this regard, a resilient O-ring 44 is looped around the hinge pin 34 at two locations to define the resilient members 42, with two parallel lengths 50 and 52 of the O-ring 44 extending between the main body 18 and the lid 22, as best seen in FIG. 2C.
The lanyard loop 16 includes a ring 54 that is preferably sized to receive a finger of a user and/or an attachment clip or carabiner, and a shank or leg 56 that connects the ring 54 to the hinge knuckle 38.
The lid 22 preferably carries a resilient member 58 for sealing engagement with the drinking port 24, with the lid 22 in the closed position. The resilient member 58 preferably has a cross-sectional shape that conforms to, but is slightly larger than the cross-sectional shape of the drinking port 24. The resilient member 58 is compressed between the lid 22 and the main body 18 to provide an opening force that urges the lid 22 from the closed position. In this regard, a spring loaded latch 60 is mounted on the main body 18 for transverse translational motion so as to be selectively engageable and disengageable with a catch 62 provided on the lid 22, with engagement of the latch 60 and the catch serving to retain the lid 22 in the closed position and actuation of the latch 60 by a user serving to disengage the catch 62 and allow the lid 22 to be moved to the open position. It should be appreciated that while a preferred form of the latch 60 is shown, in some applications other forms of latches can be used, many of which are known.
Preferably, the main body 18 includes a longitudinally extending skirt 64 that is sized and configured for engagement with the opening 14 of the beverage container 12. In the illustrated embodiment, the skirt 64 is sized to fit within the opening 14 and includes male threads 66 for engagement with female threads formed in the opening 14 of the beverage container 12. A resilient O-ring seal 70 is also carried on an O-ring gland provided on the skirt in the illustrated embodiment for sealing engagement with the opening 14. It should be appreciated that in some applications, depending upon the construction of the beverage container, the skirt 64 may be engageable with an exterior side of the opening 14 of the beverage container 12 and may include other types of releasable fasteners, such as a snap fastener. Furthermore, it should be appreciated that in some embodiments, a seal or gasket may be carried on the beverage container 12, in which case there would be no need for a resilient O-ring seal or gasket on the skirt 18. Preferably, as best seen in FIG. 5C, the main body 18 also includes a drinking lip 72 that surrounds a recess 74 in which the drinking port 24 is located. It should be appreciated that depending upon the application, the drinking lip 72 and the recess 74 can take on many different forms, including having one or both eliminated.
Any suitable rigid structural materials, including plastic and metal, can be used to form the components 16, 18, 22, and 34, with one preferred construction for the components 16, 18 and 22 being injection molded plastic or composite. Any suitable resilient materials, such a silicon rubber, can be used to form the components 42, 44, 58, and 70.
While a preferred embodiment of the lid 10 has been shown, it should be appreciated that modifications to general geometric shapes, relative locations, and such are possible within the scope of the invention. For example, although the lid 22 and ring 54 are shown to have generally circular configurations, other geometric shapes are possible depending upon the desires of each application. As another example, while the drinking port 24 is shown as having a somewhat oval shape, other geometric shapes are possible. As yet another example, while it is preferred for the upper surface 26 to include the recess 28 for flush mounting of the lanyard loop 16, in some applications, the recess 28 may not be desired and the lanyard loop 16 may lay on top of the surface 26. As yet another example, while the lanyard loop 16 is shown as being hinge mounted to the main body 18; in some applications it may be desirable to hinge mount the lanyard loop onto the lid 22. As yet a further example, while a certain number of hinge knuckles have been shown on each of the different components 16, 18, and 22, other numbers and combinations of hinge knuckles may be desired depending upon the particular application. As yet a further example, while the resilient members 42 and 58 are preferred, in some applications one or both may not be desirable.
It should be appreciated that the provision of the rigid lanyard loop 16 on the stopper 18 for movement between stowed and deployed positions allows for the stopper 18 to provide the convenience of a lanyard loop 16, without the inconvenience of having the lanyard loop 16 always extend upwardly and away from the stopper 18.
