The present invention relates to a lid for a container, and more specifically to a lid which finds usefulness in dispensing a liquid from a container and which further can be easily and reliably assembled in a manner not possible, heretofore.
The inventor and the assignee of the present application have endeavored to develop a wide variety of drinking containers for use in sports and other recreational pursuits. As of late, many individuals have adopted the practice of carrying a drinking container with them to sports, and other activities, so that they may conveniently consume beverages of their choice at any time which is convenient to them. Containers for holding liquids have taken on various designs depending upon whether the fluid to be consumed is a hot beverage, cold beverage or a beverage, for example, that may have a high sugar content. In the cases of hot and cold beverages, various thermally insulated containers have been commercially introduced. Further, dispensing lids used with such beverage containers have had various designs. Some of these designs have operated with various degrees of success. In some cases, the dispensing containers and more specifically, the dispensing lids thereof have had rather complex mechanical arrangements. These complex designs have created perceived difficulties inasmuch as the use of these drinking containers with, for example, sugary beverages has often made it difficult for a consumer to effectively clean the lid so as to remove sugary residue left by the beverage product. This sugary residue, if left unattended, would tend to encourage the growth of bacteria, and often, over time, impede the operation of the dispensing lid by causing the component part of the dispensing lid to stick together, or otherwise jam thereby preventing the correct operation of the dispensing lid.
Additionally, many of the earlier developed dispensing lids for fluid containing vessels of various sorts have not operated effectively to seal the fluid container from leakage when the container has been inverted, such as might occur in a backpack or when the container has been subjected to vibrations associated with it being carried at a sporting event, or during exercise such as when it is used on a bicycle or the like. While some dispensing lid designs have been proposed which address these shortcomings, these same lids, as a general matter, are quite complex in their overall design and are therefore costly to manufacture.
Therefore, a lid for a container which avoids the detriments associated with the prior art designs, and which further provides a means for readily sealing a container and thereafter allowing the effective dispensing of a liquid or other fluid enclosed from the container, and which is easy to manufacture and operate is the subject matter of the present application.
A first aspect of the present invention relates to a lid for a container which includes a base member which releasably sealably couples to a container which encloses a liquid to be dispensed, and wherein the base member has a first end which releasably sealably couples with the container, and an opposite distal end, and wherein an aperture is formed in the base member and is located adjacent to the second end thereof, and wherein the base member further has a diminishing outside diametral dimension as measured from the first end thereof, and extending in the direction of the second end; and a selectively rotatable cover member engageable with the base member, and which is screwthreadably rotatable relative thereto so as to facilitate the release of fluid from the container, and wherein the rotatable cover member matingly engages the base member by telescopingly receiving a portion of the base member, and then engages the base member in a snap-fit manner by moving along a linear path of travel and in the direction of the base member, and wherein the rotatable cover member thereafter rotates along a given course of travel relative to the base member.
Still another aspect of the present invention relates to a lid for a container which includes a base member which releasably sealably couples to a container, and wherein the base member has a main body defined by a longitudinal axis, and which further has a first portion which is defined by a circumscribing, outside facing sidewall, and an inside facing sidewall which releasably sealably mates with the container, and wherein the outside facing sidewall has a predetermined outside diametral dimension, and which is further symmetrically oriented about the longitudinal axis, and wherein the base member includes a second portion, which is made integral with the first portion, and which further has a circumscribing and outside facing sidewall which has a predetermined outside diametral dimension which is less than the outside diametral dimension of the first portion, and wherein the base member includes a third portion, which is made integral with the second portion, and which has a circumscribing outside facing sidewall, and an opposite inside facing surface which defines a fluid passageway which terminates at a dispensing aperture which is located near a distal end of the third portion, and wherein a thread channel, and an access passageway is formed in the outside facing sidewall of the second portion; a selectively rotatable cover member, having a main body with an outside facing, and an opposite, inside facing surface, and wherein the inside facing surface defines a cavity which telescopingly receives the second and third portions of the base member therein, and wherein a pair of posts are mounted on the inside facing surface of the cover member and extend inwardly thereof, and are first, matingly received in, and then pass through the access passageway, and are then received within the thread channel which is defined by the second portion, and wherein rotation of the cover member in a given direction relative to the base member either moves the cover member toward, or away from the base member, and wherein the cover member defines an aperture which is substantially coaxially aligned with the dispensing aperture which is formed in the third portion of the base member; and a seal mounted on the third portion of the base member, and which is located between the dispensing aperture and the second portion, and wherein the seal engages the inside facing sidewall of the cover member which defines the fluid passageway, and wherein the cover member, when rotated relative to the base member, moves either towards, or away from, the base member, and wherein the cover member when rotated in a first direction moves away from the base member, and a source of fluid contained in the drinking container may then pass through both the dispensing aperture formed in the third portion, and the aperture formed in the cover member, and wherein rotation of the cover member in a second direction causes the cover member to advance toward the base member and substantially prohibits the source of fluid from passing through the aperture formed in the cover member.
These and other aspects of the present invention will be described in greater detail hereinafter.
Preferred embodiments of the invention are described below with reference to the following accompanying drawings.
This disclosure of the invention is submitted in furtherance of the constitutional purposes of the U.S. Patent Laws “to promote the progress of science and useful arts” (Article 1, Section 8).

The pair of thread channels 55 include first and second thread channels 81 and 82, respectively. The first and second thread channels are formed in substantially opposite positions on the outside facing surface 42 of the second portion 32, and further each have opposite first and second ends 83 and 84, respectively. The first and second thread channels are operable to matingly threadably cooperate with the rotatable cover member which will be described in greater detail, hereinafter. Further, the respective thread channels each have a substantially uniform depth dimension when measured between the first and second ends 83, 84 thereof. In relative comparison to the first and second access passageways 61 and 62, the depth dimension of the first and second thread channels 81 and 82 is greater than the depth dimension as measured at the second end 64 of the respective first and second access passageways 61 and 62. As seen in the drawings, the first end 83 of the respective first and second thread channels 81 and 82 is located adjacent to the flange region 45; and the second end 84 is located adjacent to the flange region 53. As further seen in the drawings, the first and second access passageway 61 and 62 intersect with the first and second thread channels 81 and 82 at a point 85 which is located at approximately midway, or intermediate, the first and second ends 83, 84 thereof. As noted earlier, the respective thread channels 81 and 82 have a substantially uniform depth dimension as measured along the length of the respective thread channels 55, and the depth dimension of the respective access channels 61 and 62 decreases as the depth dimension is measured from the third portion 33, and in the direction of the first portion 31 thereof.

More specifically, when the pair of posts 125 are located at the first end 83 of the first and second thread channels 81, 82, the selectively rotatable cover member 110 is operationally positioned so as to prohibit the release of liquid 15 from the cavity 14 because the distal end 92 of the third portion 33 sealingly occludes the aperture 113 which is formed in the second end 112 thereof. As rotatable force is applied to the cover member 110 to cause rotation in a counterclockwise direction, the rotatable cover member 110 moves longitudinally outwardly, and away from the first portion 31 of the base member 30. As the rotatable cover member 110 moves away from the first portion 31 of the base member 30, and the pair of posts 125 move along the respective first and second thread channels 81 and 82, the second end 92 moves from its occluding position relative to the aperture 113 into a nonoccluding position. When the respective posts 125 are positioned at the second end 84 of the respective first and second thread channels 81, 82, the selectively rotatable cover member 110 is spaced away from the first portion 31 of the base member 30, and liquid 15, from the cavity 14, can be dispensed from the container 11. When this event happens, liquid 15 moves through the fluid passageway 105 which is defined by the base member 30, and then pass through the second fluid passageway 123 as defined by the selectively rotatable cover member 110. The fluid or liquid, of course, escapes through the plurality of dispensing apertures 95 which are formed in the third portion 33. To close or seal the lid 10, rotational force is applied in a clockwise direction, and the pair of posts 125 move from the second end 84 of the respective first and second thread channels 81 and 82, to the first end 83 thereof. As this clockwise rotation occurs, the rotatable cover member 110 advances or moves longitudinally towards the first portion of the base member 30 until the respective posts 125 reach the first end 83 thereof. At that point, again, the second end 92 of the third portion 33 is positioned in a substantially occluding, and fluid impeding relationship relative to the aperture 113 which is formed in the selectively rotatable cover member 110. This prevents fluid 15 from being dispensed from the container 11. Further, a resilient fluid seal cooperates with the rotatable cover member 110 so as to prohibit fluid 15 from escaping through the cover member 110 by passing between the cover member 110 and the second portion 32 of the base member 30.
The operation of the described embodiment of the present invention 10 is believed to be readily apparent and is briefly summarized at this point.
In its broadest aspect, the present invention relates to a lid 10 for a drinking container 11 which includes, among other things, a base member 30 which releasably sealably couples to a container 11 which encloses a liquid 15 to be dispensed. Further, the invention 10 includes a base member 30 which has a first end 34 which releasably sealably couples with the container 11, and an opposite, distal end 35. A dispensing aperture 95 is formed in the base member 30, and is located adjacent to the second end 35 thereof. The base member 30 further has a diminishing outside diametral dimension as measured from the first end 34 thereof, and extending in the direction of the second end 35. The invention in its broadest aspects includes a selectively rotatable cover member 110 which is engageable with the base member 30, and which is screwthreadably rotatable relative thereto so as to facilitate the release of the liquid 15 from the container 11. The rotatable cover member 110 matingly engages the base member 30 by telescopingly receiving a portion of the base member 30, and then engages the base member 30 in the manner of a snap-fit by moving along a linear path of travel as defined by the access passageways 61, 62, and in the direction of the base member 30 when being assembled. The rotatable cover member 110 thereafter rotates along a given course of travel 131 relative to the base member.
Another aspect of the present invention relates to a lid 10 for a container 11, and which includes a base member 30 which releasably sealably couples to a container 11, and which encloses a liquid 15. The base member 30 has a main body which is defined by a longitudinal axis 36, and which further has a first portion 31, which is defined by a circumscribing, outside facing sidewall 41, and an opposite inside facing sidewall 101 which releasably sealably mates with the container 11. The outside facing sidewall 41 has a predetermined outside diametral dimension, and which is further symmetrically oriented about the longitudinal axis 36. The base member 30 also includes a second portion 32 which is made integral with the first portion 31, and which further has a circumscribing and outside facing sidewall 42 which has a predetermined outside diametral dimension which is less than the outside diametral dimension of the first portion 31. The base member 30 also includes a third portion 33 which is made integral with the second portion 32, and which further has a circumscribing outside facing sidewall 43, and an opposite inside facing surface 103 which defines a fluid passageway 105 which terminates at a dispensing aperture 95. The aperture 95 is located near a distal end of the third portion 33. A plurality of thread channels 81, 82, and access passageways 61, 62 are formed in the outside facing sidewall of the second portion 32. In the present invention 10, a selectively rotatable cover member 110 is provided, and which has a main body with an outside facing, and an opposite, inside facing surface 121, 122, respectively. The inside facing surface 122 defines a cavity 120 which telescopingly receives the second and third portions 32 and 33 of the base member 30, therein. A pair of posts 125 are mounted on the inside facing surface 122 of the cover member 110, and extend radially, inwardly relative thereto, and are first, matingly received in, and then pass through the respective access passageways 61, 62, and are then received within the respective thread channels 81, 82 which are defined by the second portion 32. As earlier discussed, the rotation of the cover member 110 in a given direction relative to the base member 30 either moves the cover member 110 towards, or away from the first portion 31 of the base member 30. The cover member 110 defines a fluid passageway 123, and an aperture 113 communicates with the fluid passageway 123, and is further substantially coaxially aligned with the dispensing apertures 95 which are formed in the third portion 33 of the base member 30.
The invention 10 further includes a seal 94 which is mounted on the third portion 33 of the base member 30, and which is further located between the dispensing apertures 95, and the distal end of the third portion 33. The seal 94 engages the inside facing sidewall 122 of the cover member 110 which defines the fluid passageway 123. The cover member 110, when rotated relative to the first portion 31 of the base member 30, moves either towards, or away from, the first portion 31 of the base member 30. The cover member 110, when rotated in a first direction, moves away from the first portion 31 of the base member 30, and liquid 15 contained in the container 11 may then pass through both the dispensing aperture 95 formed in the third portion, and the aperture 113 formed in the cover member 110. Further, the rotation of the cover member 110 in an opposite second direction causes the cover member 110 to advance or move towards the first portion 31 of the base member 30, and substantially prohibits the liquid 15 from passing through the aperture 113 formed in the rotational cover member 110. The seal 94 smoothly and sealingly moves along the fluid passageway 123 as the cover member 110 moves both towards, and then away from the base member 30 as it is rotated in a clockwise, or counterclockwise direction.
Therefore, it will be seen that the present invention 10 provides a convenient arrangement for dispensing fluids 15 from a container 11 which has not been possible, heretofore. The present invention 10 can be easily, and reliably assembled, provides a sure means by which a container 11 can be sealed against leakage, and further provides a means which are readily operable by a user, and whereby a fluid 15 can be dispensed from a container 11 in a manner not possible heretofore in an overall construction which is simple, cost effective, easy to manufacture, and readily avoids many of the shortcomings attendant with the prior art practices.
