DETAILED DESCRIPTION OF INVENTION

For purposes of this application, any terms that describe relative position (e.g., “upper”, “middle” “lower”, “outer”, “inner”, “above”, “below”, “bottom”, “top”, etc.) refer to an aspect of the invention as illustrated, but those terms do not limit the orientation in which the embodiments can be used.
A beverage container system 10 will now be described with reference to FIGS. 1-19 . The beverage container system 10 includes a container 20 to hold a beverage and a lid assembly 50 to selectively close the beverage container 20. The lid assembly 50 may engage with the beverage container 20 to form the beverage container system 10. The lid assembly 50 controls a flow of a drinking fluid from the beverage container 20.
The lid assembly 50 includes a lower lid 100 and a lid cover 200. The lower lid 100 includes one or more openings 110 to provide for fluid passage from the container 20. The lid cover 200 connects or engages to the lower lid 100 to seal against a drinking rim 132 or surface of the lower lid 100 to mostly prevent or reduce leakage of fluid from the beverage container system 10. The connection or engagement of the lid cover 200 to the lower lid 100 on the beverage container 20 generally seals the liquid in the beverage container 20. When the lid cover 200 is fully connected or engaged to the lower lid 100, the beverage container system 10 is generally leak resistant.
The lower lid 100 may include a number of different versions, configurations or varieties, depending on drinking style or preference of the user, which may all operate with the same lid cover 200 and the same beverage container 20. The lower lid 100 may include one or more openings 110 with different sized, shapes, etc. The lower lid 100 may optionally include a vent, a spout, a slow flow opening, a gulp size opening, and/or an opening to receive straw.
In this aspect, the openings 110 include a larger opening 110A and smaller opening 110B. The larger opening 110A is suitable for high volume drinking or gulping, while the smaller opening 110B is suitable for slower drinking, such as sipping. The larger opening 110A may be used with a cold beverage, and the smaller opening 110B may be used with a hot beverage. In this aspect, the larger opening 110A is approximately 180 degrees from the smaller opening 110B, i.e., on approximately opposite sides of the lower lid 100. The user orientates or rotates the beverage container system 10 such that they can choose which drink opening 110 they prefer to drink from. Of course, in other aspects, the one or more openings 110 may have a uniform size. In other aspects, the one or more openings 110 may have a semi-circular, ovular, elliptical, teardrop, geometric, organic, or other shape. In other aspects, the one or more openings 110 may have combinations of different shapes. In other aspects, a greatest axis of one of the openings 110 may be generally perpendicular to a greatest axis of the other opening 110. Also, in other aspects, the one or more openings 110 may be sized to accommodate a straw. Also, only a single opening 110 may be present in the lower lid 100.
As described below, the lower lid 100 and the lid cover 200 removably connect or engage with each other. In this aspect, the lower lid 100 removably connects or engages to the beverage container 20 to hold the lid assembly 50 to the beverage container 20. In order to fill the container 20 with a beverage, the lower lid 100 may be unscrewed from the beverage container 20, as shown in FIG. 3 , which may also remove the lid cover 200 from the beverage container 20. The user may also remove the lid cover 200 from the lower lid 100 and the beverage container 20 before unscrewing the lower lid 100 from the beverage container 20. In other aspects, the beverage container 20 may be filled by directing water through an opening in the lower lid 100.
The lid cover 200 will now be described. This lid cover 200 is shown in isolation in FIGS. 12-14 . With reference to FIG. 5 , in this aspect, the lid cover 200 includes an inner sidewall 230 and an outer sidewall 235 joined by an upper wall 240. A space 245 is formed between the inner sidewall 230 and the outer sidewall 235. When the lid cover 200 is engaged to the lower lid 100, the drinking rim 132 of the lower lid 100 fits into the space 245 and is covered by the space 245 and the lower side of the upper wall 240, which helps reduce dirt, contamination, germs etc. from contacting the drinking rim 132. The space 245 may act as a removable cover over the drinking rim 132.
In this aspect, as shown in FIG. 4 , the lid cover 200 removably engages to the lower lid 100. In this aspect, the lid cover 200 forms a stopper portion 210 that fits into a central region 115 of the lower lid 100 and covers the one or more openings 110 in the lower lid 100. The central region 115 may include a cup-like or generally open shape to receive the stopper portion 210. The stopper portion 210 nests into the central region 115 of the lower lid 100. The stopper portion 210 may be configured to help insulate the contents of the container 20, for example by including a compartment filled with air, foam, vacuum space, an insulation block, or other insulating configuration.
In this aspect, the lid cover 200 includes a handle 220 extending from the upper wall 240 of the lid cover 200. In other aspects, the handle 220 may be omitted. An exterior surface of the outer sidewall 235 may include a textured surface to provide a frictional gripping structure for the user to rotate the lid cover 200.
In this aspect, the inner sidewall 230 of the lid cover 200 includes exterior threads 232. When the lid cover 200 is engaged to the lower lid 100, the exterior threads 232 threadably engage with interior threads 133 of the lower lid 100.
In this aspect, as shown in FIGS. 5 and 6 , the lid cover 200 includes an inner rim 205 between the inner sidewall 230 and the outer sidewall 235. With respect to FIG. 11 , the inner rim 205 positions a gasket 208 against a generally circular inner diameter 131 of the drinking rim 132 to provide a seal to prevent or reduce leakage. As the lid cover 200 is fully tightened or fully engaged to lower to the lower lid 100, the gasket 208 is compressed against an upper portion of the generally circular inner diameter 131 of the drinking rim 132. In other aspects, the lid cover 200 may seal against an upper or an outer portion of the drinking rim 132 or the lower lid 100. In other aspects, the lid cover 200 connects or engages to the lower lid 100 to seal against a top edge, mouth, or other drinking surface of the lower lid 100. The gasket 208 may include a seal, compressible member, or other elastomeric member that mostly prevents or reduces leakage. The gasket 208 may be shaped to include a gasket main body and a gasket flange, in which the gasket flange is flexible and seals against the lower lid 100 or some portion thereof In other aspects, the gasket 208 may include one or more fins that normally extend outward, i.e., generally perpendicular to a central vertical axis of the beverage container 20. When the lid cover 200 is tightened to the lower lid 100, such fins may bend and/or flex to making a sealing contact against the generally circular inner diameter 131.
One benefit of certain aspects of this invention is that the sealing connection between the lid cover 200 and the lower lid 100 does not occur right at the drink openings, which allows for flexibility in size and shape of the drink openings. Accordingly, the same lid cover 200 could also be used on lower lids 100 having various shapes and drink opening configurations.
Another benefit of certain aspects of this invention is that the sealing connection of the lid cover 200 does not occur at the top of the drinking rim 132, which does not limit or restrict the size and shape of the drinking rim 132.
The lower lid 100 will now be described. The lower lid 100 is shown in insolation in FIGS. 15-17 . The lower lid 100 includes the one or more openings 110 to provide for fluid passage. The lid cover 200 removably engages or connects to the lower lid 100 over the one or more openings 110. The lower lid 100 may include any number of openings 110 or other fluid passages.
In this aspect, the lower lid 100 includes an inner sidewall 130 and an outer sidewall 140. In this aspect, the inner sidewall 130 forms the generally circular inner diameter 131 having interior threads 133 that threadably engage with the exterior threads 232 of the lid cover 200. The interior threads 133 and the exterior threads 232 may include a linear interlocking arrangement as shown, a helical arrangement, or other insert and rotate locking or twist to lock arrangements.
The inner sidewall 130 further transitions into the drinking rim 132. The inner sidewall 130 of the lower lid 100 defines the central region 115. The central region 115 is configured to removably receive the stopper portion 210 of the lid cover 200. The lower lid 100 forms a central wall 120 that extends from the inner sidewall 130. The central wall 120 includes the one or more openings 110. The central wall 120 may extend from one side of the inner sidewall 130 to the other side of the inner sidewall 130.
In this aspect, the lower lid 100 includes the inner sidewall 130 and the outer sidewall 140. A space 145 is formed between the inner sidewall 130 and the outer sidewall 140. The space 145 receives an upper portion or neck region 24 of the beverage container 20 when the lower lid 100 is engaged or connected to the beverage container 20.
The stopper portion 210 of the lid cover 200 includes a lower surface 250, which covers the one or more openings 110 when the lid cover 200 is engaged to the lower lid 100. The lower surface 250 may include a generally flat surface that covers a generally flat upper surface 122 of the central wall 120 of the lower lid 100. In alternative aspects, the lower surface 250 and central wall 120 may have other configurations, such as diagonal to each other or such configuration where the surfaces may not be parallel. One benefit of this aspect is that since the lower surface 250 and central wall 120 do not have to touch, the orientation of the surfaces are not required to be parallel. The beverage container system 10 generally includes an open configuration for drinking and a storage configuration. In the open configuration, the lid cover 200 is usually disengaged from the lower lid 100. In the storage configuration, the lid cover 200 is engaged to the lower lid 100 and the gasket 208 is compressed against the generally circular inner diameter 131 of the drinking rim 132.
The inner sidewall 130 of the lower lid include exterior threads 135 that are positioned on a generally circular outer diameter 137 of the lower lid 100. The exterior threads 135 threadably engage with interior threads 30 of the beverage container 20.
In this aspect, the lower lid 100 threadably engages to the beverage container 20. With reference to FIG. 2 , the walls 22 of the upper portion or neck region 24 of the beverage container 20 include an inner surface 25 having the interior threads 30. The interior threads 30 of the beverage container 20 receive the exterior threads 135 of the lower lid 100 to engage the lower lid 100 to the beverage container 20. The beverage container 20 includes walls 22 defining an interior volume 35 to hold a beverage. The walls 22 of an upper portion or neck region 24 of the beverage container 20 include the inner surface 25 having the interior threads 30.
A gasket 180 is engaged to a bottom outer diameter 185 of the lower lid 100. In this aspect, an outer groove 190 proximate to the bottom outer diameter 185 holds the gasket 180. The gasket 180 seals against the beverage container 20 when the lower lid 100 is threaded to the beverage container 20.
In other aspects, the lower lid 100 may engage to the beverage container 20 in other manners than a threaded engagement, including a snap-fit engagement, frictional engagement, bayonet engagement, or other engagements configured to selectively attach the lower lid 100 to the beverage container 20.
In other aspects, the lid cover 200 may engage to the lower lid 100 in other manners than a threaded engagement, including a snap-fit engagement, frictional engagement, bayonet engagement, or other engagements configured to selectively attach the lid cover 200 to the lower lid 100.
In other aspects, the relative positions of the interior threads 133 and the exterior threads 135 of the lower lid 100 and the exterior threads 232 of the lid cover 200 may be reversed such that the lid cover 200 utilizes interior threads to threadably engage with exterior threads of the lower lid 100.
In this aspect, the container 20 has a thermally insulated, double wall construction. In other aspects, the container 20 includes a non-insulated single-layer or multilayer construction or other insulated constructions. The container 20 may be formed from moldable food-grade plastics, thermoplastics, stainless steel, other metals and metal alloys, other plastics, or any combination thereof
With respect to FIG. 18 , a second lower lid 101 is shown, which includes four drink openings 111 equally spaced around a diameter of the central wall 120, such that the user may drink from any side of the beverage container 20.
With respect to FIG. 19 , a third lower lid 102 is shown for use with a hot beverage, which includes a drink opening 112 and a vent 113 to promote flow and reduce a vacuum from forming within the beverage container 20.
