Abstract
A beverage container includes a body member and a lid that fits thereon in only a single orientation. One way this is accomplished is by using a lid that has an asymmetric perimeter profile such as a reniform. Another way is by using a projection on the body member that uniquely mates with a receiving area on the lid. A first orientation indicator, such as a groove, may be disposed on the body member to indicate the orientation of the container to the user's hand. A second orientation indicator may be disposed on the lid to help guide a user's lips to a drinking aperture and/or assist in preventing spillage.In a preferred embodiment, the body member includes a clear outer member and an inner member, wherein an advertising medium may be disposed between the two members for viewing.
Description




FIELD OF THE INVENTION




The present invention relates generally to beverage containers having lids, and more particularly, to a reusable beverage container.




BACKGROUND OF THE INVENTION




Drinking mugs and beverage containers have been adapted over the years to facilitate beverage consumption during travel activities, such as riding in an automobile, bus, train, or airplane. For example, commuters often fill such containers with their morning coffee, tea, juice, etc. to consume during their journey to work each day. These containers generally consist of a container member, or body member, and a lid member with a drinking aperture that fits over the container member to minimize spillage during travel. See, e.g., U.S. Pat. No. 5,249,703 to Karp, U.S. Pat. No. 5,918,761 to Wissinger, and U.S. Design Pat. No. 399,392 to Husted.




Prior art cylindrical and frusto-conical beverage containers allow the lid member to be placed on the body member so that the drinking aperture may be oriented in a different position relative to the container member each time the lid is removed and replaced on the container member. Users of such containers must therefore shift their attention away from other activities and look at the container to locate the drinking aperture prior to drinking from the container. In the case of containers having handles, users must take care to correctly orient the lid on the container so that the drinking aperture is in the appropriate position relative to the handle. Even when the lid is properly oriented relative to the handle, users will need to locate the drinking aperture so that they do not spill the beverage as they drink from the container. Since users of such containers may be driving automobiles, any distraction or shift in attention away from the driving activity could be quite dangerous. In addition, while working, reading, and/or conversing in the workplace or on public transportation, users may be inclined to reach for, and take a drink from, a beverage container without looking for the drinking aperture.




Thus, there is a need for a beverage container having a lid member wherein a user can easily locate the drinking aperture without making visual contact with the aperture. In this regard, a beverage container can be provided wherein the lid may only be placed over the body member in a single orientation and includes an indicator on the body member to indicate the orientation of the container to a user's hand. It is also desirable to provide a beverage container with a lid that guides a user's lips to the drinking aperture as the container is brought into contact with the user's lips. Such a container will allow a user to properly orient the container for drinking without the user having to shift his or her attention away from other activities to look at the container lid.




SUMMARY OF THE INVENTION




In one preferred embodiment, the present invention is a beverage container comprising a body member and a lid member, the body member having a base, a side surface, an upper end, and an interior volume formed from the base and side surface. The base has a substantially circular cross-section and the upper end has a substantially reniform cross-section. The lid member includes a drinking aperture and is configured to attach to the body member in only a single orientation. When properly attached, the lid forms a substantially fluid-tight seal with the body member.




A first orientation indicator is disposed on the side surface of the body member to indicate the orientation of the container to a user's hand. The first orientation indicator may comprise an elongated depression in the side surface of the body member extending from or near the upper end of the body member toward the base of the body member. Preferably, the elongated depression is aligned with a point on the circumference of the lid member nearest the drinking aperture when the lid is attached to the body member. In one variation of this embodiment, the elongated depression extends to the upper end of the body member thereby forming a reniform cross-section. A reniform-shaped upper end would ensure that the lid fits on the body member in only a single orientation.




In another variation, the first orientation indicator may comprise at least one tactile projection formed on the side surface of the body member. This projection may be in addition to, or in place of, the elongated depression described above.




The beverage container may further comprise a second orientation indicator which is disposed on the lid member and is configured to assist in guiding a user's lips to the drinking aperture without the user having to look at the container. The second orientation indicator may be a depression in the lid substantially aligned with the elongated depression of the first orientation indicator, if used. This results in the lid having a substantially reniform shape. The lid may further comprise a vertical ridge along at least a portion of the perimeter of the lid rising above the surface where the drinking aperture is located. The second orientation indicator may also include, in place of or in addition to the first depression in the lid, a vertical depression in the vertical ridge that may assist the user in locating the drinking aperture and aid in preventing spillage during drinking.




In a second embodiment, the base of the body member has a substantially circular cross-section, while the upper end of the body member has a substantially elliptical cross-section. To ensure that the lid fits on the body in only a single orientation, the upper end of the body member may include an alignment projection that mates with a receiving area located on the lid member when the lid is attached to the body member.




In another preferred embodiment, the body member includes an inner container member and an outer member, wherein the inner member fits within and is attached to the outer member. A perimeter flange on the inner container member engages and is sealed to a perimeter notch on the outer member. The inner container member is attached to the outer member along the flange-notch interface. Preferably, the outer member is made of a transparent material so that an advertisement medium, such as printed paper or cardboard, may be disposed between the inner container member and the clear outer member for viewing.




The outer member includes a base and a side surface. The inner member has an upper end for attachment to the lid. The base has a substantially circular cross-section and the upper end of the inner member has a substantially reniform cross-section. A reniform-shaped lid member having a drinking aperture is configured to attach to the upper end of the inner member in only a single orientation. The lid member of this embodiment is otherwise similar to the lid member of the embodiments previously discussed. A first orientation indicator, as previously described, may be disposed on the side surface of the outer member, and a second orientation indicator, as previously described, may be disposed on the lid member.




In another embodiment utilizing an outer and inner member, the upper end of the inner member has a substantially elliptical perimeter profile, rather than the reniform profile. The inner member preferably includes an alignment projection that mates with a receiving area located on the lid member to ensure that the lid member can be attached to the inner container member in only a single orientation. Features of other embodiments as described previously, including the first and second orientation indicators, may be utilized.




The beverage container may be formed of plastic (i.e., styrene acrylonitrile, polystyrene, polyethylene, polyvinyl chloride, etc.) or any other suitable material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Reference is now made to

FIGS. 1-8

, which are views of a first embodiment of the present invention. These figures show beverage container


10


comprising a body member


12


and a lid member


14


. The body member


12


has a side surface


16


, a base


18


, an upper end


20


, and an interior volume


22


. Preferably, the base


18


is substantially circular to facilitate placing the beverage container in beverage holders commonly found in automobiles. The lid member


14


includes a drinking aperture


24


and a vent hole


26


. The lid member


14


fits over and preferably forms a fluid-tight seal with a perimeter lip


21


at or near the upper end


20


of body member


12


. Vent hole


26


facilitates fluid flow by allowing ambient air to replace withdrawn fluid. An oval or “egg-shaped” concave depression


29


is provided for aesthetic purposes only. Lid


14


and body member


12


are configured so that the lid


14


may only be fitted over the open end


20


of the body member in a single orientation (a “single-orientation fit”).




By way of example, the single-orientation fit may be accomplished by forming both the lid


14


and the upper end


20


of the body member in a reniform (i.e., kidney-shaped) configuration. The reniform shape of the lid member is best illustrated in FIG.


2


. Since the drinking aperture


24


is fixed relative to the lid, and since the lid only fits on the body member in a single orientation, the drinking aperture is guaranteed to be in the same position each and every time the lid is placed on the body. It should be understood that the shape of the upper end


20


and lid


14


is not limited to a reniform. Rather, any shape can be selected so long as the lid attaches to the body member


12


in only a single orientation. The body member


12


may have any shape that allows for the necessary connection with the lid.




In order for the user to determine whether the beverage container is being held in the proper orientation without having to look at the container, it is preferred that the body member


12


include a first orientation indicator. The first orientation indicator can be on any portion of the body member that enables a user to confirm that the container is being held in the proper orientation.

FIGS. 1 and 5

show the first orientation indicator as an elongated depression


28


disposed on the side surface


16


of the body member


12


. The depression


28


extends from or near the upper end


20


of the body member toward the base


18


. The depression


28


is shown deepest (most pronounced) at the upper end


20


and gradually tapers, becoming more shallow toward the base


18


. The depression


28


may taper completely away before reaching the base


18


, which preferably has a circular cross-section. The depression


28


is integral with the upper end


20


of the body member thereby forming the reniform perimeter profile at the upper end of the body member


12


. Thus, the depression


28


serves two purposes—it ensures that the lid can only fit on the body in a single orientation, and it forms a part of the first orientation indicator as discussed above.




Reference is now made to

FIG. 9

, which illustrates an additional first orientation indicator. In

FIG. 9

, the first orientation indicator includes a series of tactile projections


40


on the side surface of the body member


12


. These tactile projections


40


are shown as a series of horizontal ribs or ridges, but may take the form of any type of raised surface, such as a raised dot, letter, etc. Moreover, a single tactile projection may also be used rather than a series of projections. Tactile projections


40


may supplement or replace depression


28


in performing the function of indicating the orientation of the container


10


to a user's hand. Preferably, tactile projections


40


are placed in a position on the side surface


16


so that when a user grasps the container, the user's thumb will engage the projections


40


if the container is properly oriented for drinking. If the user's thumb does not engage the projections, the user would know that the container must be re-oriented in the hand for drinking without spillage.




In one variation (not shown), the tactile projection(s)


40


may be formed on the side surface opposite the drinking aperture (i.e., 180 degrees from the location described above and shown in FIG.


9


), so that a user's finger(s) engage the projections, rather than the user's thumb. If the user's fingers do not engage the projections, the user knows that the container must be re-oriented so that the user's fingers engage the projections before taking a drink. It should be understood that the projections, as well as any other first orientation indicator, can be located anywhere on the side surface of the body member.




In other variations, the first orientation indicator may comprise a recess, groove, channel, series of dots, or any other suitable indicating structure, such as a handle. U.S. Pat. No. 4,762,229 to Wickre, which discloses a variety of tactile sensing means in the context of a disposable container is hereby incorporated by reference.




Preferably, the beverage container also includes a second orientation indicator. The second orientation indicator may assist in guiding the user's lips to the drinking aperture without the need to look at the beverage container. One embodiment of the second orientation indicator is shown in

FIGS. 1

,


2


and


6


as a lid depression


30


disposed on lid


14


. The second orientation indicator shown in

FIG. 1

coincides with the narrowest portion of the reniform profile of the lid


14


and is below the drinking aperture


24


so that it effectively receives a user's lips. When the lid member


14


is placed on the body member


12


, the lid depression


30


is preferably aligned with and substantially complements the first depression


28


, if used, thereby forming a continuous depression from or near the top of the lid member toward the base


18


of the body member, as shown in FIG.


1


. When a user raises the container to his mouth, the lips can sense the lid depression


30


, which, at its deepest point, coincides with the center line of the drinking aperture


24


. Thus, the user is able to determine that his lips will meet the drinking aperture without the need to look at the lid member.




The second orientation indicator need not utilize the lid depression


30


described above. The lid member


14


preferably includes a vertically extending ridge


32


around at least a portion of the perimeter of the lid and forms an uppermost surface along the perimeter of the lid. Below the vertical ridge


32


, the lid includes an aperture surface


34


that includes the drinking aperture


24


. In lieu of, or in addition to the lid depression


30


, the second orientation indicator may comprise a vertical depression


36


in the vertical ridge


32


that can help a user locate the drinking aperture and/or prevent spillage. This is best shown in FIG.


4


. The lowest point of the vertical depression


36


(labeled “D” in

FIG. 4

) preferably coincides with the centerline of the drinking aperture


24


.





FIG. 7

is a cross-sectional view through container


10


, illustrating how lid member


14


attaches to body member


12


. As shown in the detailed view of

FIG. 7

, a groove


23


on the underside of the lid


14


is aligned with a lip


21


of body member


12


forming an interference or friction fit. The lid includes a biasing surface


25


, which urges the lip


21


into the groove


23


. The friction fit between lip


21


and groove


23


preferably provides a substantially fluid tight seal to minimize beverage leakage. Preferably, a pull-tab


27


(shown in

FIGS. 2 and 6

) facilitates removal of the lid


14


from body member


12


.




In a second embodiment (shown in FIGS.


10


-


17


), the body member


12


has a circular base


18


and an upper end


20


having a perimeter shaped in a substantially elliptical configuration. Preferably, an alignment projection


61


(shown in

FIGS. 16 and 17

) on the body member


12


mates with a receiving area


63


formed on the lid member so that the lid only fits on the body member in a single orientation. The alignment projection


61


may take any shape that allows for the proper alignment. Also, the projection-receiving area arrangement


61


-


63


may assist in providing a fluid tight seal by ensuring proper alignment and fit of the lid to the body member.




As shown in

FIGS. 10 and 14

, elongated depression


28


is recessed into the side surface of the body member


12


, similar to the first embodiment but does not extend to the top of the body member


12


, nor does it extend into the lid member


14


. The elongated depression


28


preferably extends from an area below the lid when the lid is attached to the body member towards the base


18


, tapering away before it reaches the base


18


so that the base


18


has a substantially circular perimeter. If this is the case, the upper end


20


of the body member


12


is preferably elliptical as shown in FIG.


14


. In either of the first two embodiments, elongated depression


28


is preferably aligned with a point on the circumference of the lid member


14


nearest the drinking aperture


24


. A user's thumb would then engage the elongated depression


28


when raising the container to the mouth for drinking. If the user's thumb does not contact the depression


28


, the user is aware that he must re-orient the container


10


in the hand prior to taking a drink to avoid spillage. In alternative embodiments not shown, the depression


28


may be on the side surface opposite the drinking aperture, so that a user's finger(s) engage the depression, rather than the user's thumb. Similarly, if the user's fingers do not engage the depression, the user knows that he must re-orient the container so that his fingers do engage the depression before taking a drink. The location and shape of the depression is not limited to the above embodiments. It should be understood that the depression, or other first orientation indicator can be located anywhere on the side surface and may include any of the variations previously discussed with the first embodiment.




The lid member of the second embodiment is substantially similar to that for the first embodiment, with two exceptions. First, as previously described, the lid includes a receiving area


63


for the alignment projection


61


so that the lid fits on the body member only in a single orientation. Other methods for ensuring that the lid only fits on the body member will be understood by those skilled in the art. Second, the shape of the lid is substantially elliptical rather than kidney-shaped as in the first embodiment. Otherwise, the lid members of the first and second embodiments are similar with respect to the various alternatives for the second orientation indicator.




Reference is now made to

FIG. 18

, which shows the components of a third embodiment of the invention. In this embodiment, the container includes an inner member


42


having an upper end


44


and an interior volume


46


. The inner member is configured to fit within and be attached to an outer member


48


. The outer member


48


is preferably made from a transparent material. Outer member


48


has a base


50


and a side surface


52


. The container includes a lid


14


which is configured to fit over the upper end


44


of inner member


42


in a manner similar to that described for the first embodiment, preferably forming a fluid-tight seal between the lid


14


and inner member


42


. A first orientation indicator in the form of an elongated depression


54


may be disposed on the side surface


52


of the outer member


48


in a manner similar to the first embodiment. For example, depression


54


may extend from the top of the outer member toward the base


50


. The elongated depression


54


is shown deepest at the top of outer member


48


and gradually tapers, becoming more shallow toward the base


50


. In the embodiment shown, the depression


54


tapers completely away before reaching the base


50


, which has a substantially circular perimeter profile. The depression


54


results in the upper portion of the outer member having a reniform perimeter profile.




The elongated depression


54


is preferably in substantial alignment with the drinking aperture


24


, as in the first embodiment. In this configuration, a user's thumb would engage the depression


54


when raising the container to the mouth for drinking. If the user's thumb does not contact the depression, the user is aware that he must re-orient the container in his hand prior to taking a drink. In alternative embodiments not shown, the depression may be on the side surface opposite the drinking aperture (i.e., 180 degrees from the location described above) so that a user's finger(s) engage the depression, rather than the user's thumb. Similarly, if the user's finger(s) do not engage the depression, the user knows that he must re-orient the container so that his fingers engage the depression before taking a drink. In another alternative configuration (not shown), a series of projections, similar to those shown in

FIG. 9

may replace or supplement depression


54


. Any of the first orientation indicators described for the first embodiment can be used on the outer member of this embodiment.




An advertising medium


70


, such as printed paper or cardboard, may be disposed between the inner member


42


and the outer member


48


prior to attaching the two members together. One advantage of this shape is that it allows for an increased surface area for the advertising medium to display graphic material as compared to a container with a cylindrical shape. After insertion of the advertising medium


70


, the inner member


42


is placed within and attached to outer member


48


. One method of doing this is as follows. A perimeter flange


47


on inner member


42


mates with a perimeter notch


51


of the outer member


48


. The inner and outer members


42


and


48


are then attached, preferably by radio-frequency, heat, or electronic sealing along the interface between flange


47


and notch


51


. Reference is also made to

FIG. 20

showing in more detail the relationship between the inner and outer members when connected. It should be understood that the inner member


42


and outer member


48


can be attached in any manner that holds the two members in a fixed position relative to each other and that preferably allows for the display of the advertising medium if used.




While

FIG. 18

shows an embodiment of the present invention where the lid


14


and upper end of inner container member


42


have a reniform perimeter profile, one of ordinary skill in the art will recognize that this embodiment may be modified so that the lid and upper end may have an elliptical perimeter profile similar to that shown in

FIGS. 10-17

for the second embodiment. This modification merely requires that the depression


54


, if used, not extend as far as the very top of the inner member.

FIG. 19

shows such an embodiment. The perimeter profile of this embodiment allows for an increased surface area to display graphics on the advertising medium.




In the embodiment shown in

FIG. 19

, the elongated depression


54


is used as the first orientation indicator. The lid member


14


is configured to attach to the upper end of the inner member in only a single orientation preferably by using an alignment projection and mating receiving area similar to that previously discussed for the second embodiment. The lid attaches to the inner container member the same way as in the previous embodiments utilizing a perimeter lip and groove as in

FIGS. 5

,


7


and


8


. Unlike the embodiment shown in

FIG. 18

, the second orientation indicator is not a depression in the lid substantially aligned with the elongated depression. Instead, the second orientation indicator is a vertical depression in the vertically extending ridge on the lid, similar to that shown in

FIG. 13

for the second embodiment. The embodiment of

FIG. 19

may be modified to utilize any of the first orientation indicators previously discussed. In other ways, this embodiment is similar to the third embodiment. For example, as shown in

FIG. 20

, the inner member


42


is attached to the outer member, preferably by radio frequency, heat, or electronic sealing along the interface between the flange


47


and notch


51


.




The body member


12


and lid member


14


are preferably made of a thermoplastic (e.g., styrene acrylonitrile, polystyrene, polyethylene, polyvinyl chloride, etc.), or any other suitable material, and may be manufactured by an injection molding process.




While the present invention has been described with reference to the preferred embodiments, those skilled in the art will recognize that numerous variations and modifications may be made without departing from the scope of the present invention. This is especially true with regard to the specific shape and configuration of the lid, body member, and first and second orientation indicators. For example, it should be understood that the lid member


14


and body member


12


may be configured to threadably engage each other. The lid may screw on the inside of the open end of the body member or on the outside. If the lid is threadably connected to the body member, the connection should include a mechanical stop within the threads to insure that once the lid is screwed fully onto or within the body member, the drinking aperture will be consistently in the same location relative to the body member. The lid


14


may also fit within the open end


20


of the body member


12


in a cork-like manner, rather than snapping around the outside of the upper end of the body member. In this regard, the portion of the lid that would fit within the body member should form a resistance fit with the inside of the body member


12


so that it remains attached. In addition, the beverage container may be formed with a handle attached to the body member. Accordingly, it should be clearly understood that the embodiments of the invention described above are not intended as limitations on the scope of the invention, which is defined only by the following claims.
