Abstract
A vapor directing baffle for a beverage container. The combination of a beverage container and a tight fitting lid in combination with an internal baffle forces aroma laden vapor (located between the interior of the lid and the liquid surface of the beverage in the container) outward through openings in the lid, when the beverage container is tipped from the level position to the drinking position. This vapor pumping action places the outwardly flowing aroma beneath the nose of a user, thereby allowing the user to enjoy the aroma of the beverage.
Description




TECHNICAL FIELD




The present invention relates to beverage containers, and, more particularly, to a covered beverage container that directs vapor and aroma emanating from a beverage in a predetermined direction. Such containers are especially useful for serving coffee and tea.




BACKGROUND




It is well known that the aroma of a beverage comprises a large part of the flavor of the beverage. This is because while most human taste buds sense only sweet, salt, sour, and bitter tastes, the human nose can distinguish between approximately 10,000 distinct odors.




Presently, covered beverage containers typically prevent the consumer from enjoying, to a very significant degree, the aroma of the beverage when the beverage is consumed while the lid of the container remains in place. A few covered beverage containers of which I am aware allow for aroma laden air vapor to travel through drink openings or other small openings for venting air. However, because in typical containers the opening of the container must remain covered in order to achieve the benefits of a lid (such as reduced risk of spilling and retaining the heat of hot beverages), traditional lidded beverage containers have resulted in very little of available aromas actually reaching the nostrils of the drinker.




Thus, there remains an unmet need for an improved lid for beverage containers, and for containers which can be used in combination with such lids, that include structural features that would direct available aromas to the consumer, for increased enjoyment during consumption of flavorful beverages.




SUMMARY




I have now developed a vapor directing beverage container that includes a lid and a unique internal baffle. The lid has a drink opening to allow beverage to pass through the lid while the lid remains attached to the container. At least one vent opening, and preferably two or more vent openings (in addition to the drink opening) are provided to allow vapor within the container to pass through the lid. In one embodiment, the internal baffle is sized and shaped so that when it is inserted into the container, the baffle substantially seals against the container inner side walls, and the baffle extends down into the container so that the bottom of the baffle is very near to the bottom of the container. The space between the bottom of the baffle and the bottom of the container allows liquid in the container to flow freely from one side of the baffle to the other side of the baffle. The baffle sealably attaches to, or is integrally and sealingly provided with, the lid of the container. The baffle is positioned between the drink opening and one vent opening so as to divide the space within the container into at least two chambers. When the container is tipped to allow beverage to flow out of the drink opening, vapor within one chamber is forced out of at least one opening in the lid while air from outside the container is simultaneously drawn into the container through one or more openings on the other side of the baffle. The precise location, shape, and number of vent openings through which vapor is directed can vary depending upon the size and shape of the lid and of the container in order control the direction and speed of the vapor.




More generally, a covered beverage container is provided for pumping vapor from within the container to the vicinity of the user's nose when the container is tipped from a level, upright or generally vertical position to a more generally horizontal oriented drinking position, or when the container is returned from the drinking position back to a level, upright position.




In accordance with another aspect of the present invention, the beverage container includes a lid through which beverage can be drunk with the lid still in place, thereby reducing the amount of spillage from the container and retaining the heat of a hot beverage while the container remains at rest.




The method of the present invention utilizes a baffle that, when the container is tipped, allows the rising liquid level in one half of the container to force vapor out of one or more of the vapor openings in the lid, and then towards the user's nose. This method provides a unique mechanism, beyond mere volatilization, by which the aroma of the beverage can be enjoyed by the user.




The foregoing briefly described vapor directing beverage container structure, and my method of directing aromas to the consumer of a beverage, and the various objectives, features and advantages of the invention will be more readily understood upon consideration of the following detailed description, taken in conjunction with careful examination of the accompanying drawing.

DETAILED DESCRIPTION




Attention is directed to

FIG. 1

of the drawing, which depicts a simple embodiment of my vapor directing beverage container


30


. The vapor directing beverage container


30


includes a container


32


with a closure lid


34


sealed to the rim of the container


32


. A baffle


36


seals against the lid


34


and the side walls of the container


32


. A gap in


38


between the bottom of the container


32


and the bottom edge of the baffle


36


allows liquid in the container


32


to flow freely from one side of the baffle


36


to the other side. The lid


34


has a drink opening


40


and vent openings


42


.





FIG. 2

shows a simplified two-dimensional schematic of the vapor directing beverage container


30


, which is shown in

FIG. 1

, where the liquid in container


46


is represented by the shaded areas


52


,


54


, and


58


. In a level position the same volume of liquid in the container


46


would occupy the shaded areas


52


and


58


. As the container


46


is tipped from the level position to the drinking position, the air volume


56


decreases. The vapor previously occupying area


54


is forced out of the drink opening


60


and out of the vent opening


62


. When the container is tipped back to the level position, the vapor in area


58


is forced out of the vent opening


64


.




FIG.


3


through

FIG. 7

depict one of the alternative embodiments of the present invention. The container


66


is any conventional configuration and construction including disposable cups of the type commonly used as carry out containers for beverages such as coffee and tea. Typically, the container


66


has downwardly converging side walls


68


and a bottom


70


so that the container


66


is an inverted frusto-conical shape. The container


66


may be fabricated from any number of materials including wax or resin impregnated paper, Styrofoam, plastic sheet or paperboard. The container typically has a bead formed on the rim


72


to facilitate attachment of a lid.




The baffle of


74


depicted in

FIG. 4

is sized and shaped to slidably fit into the container


66


as depicted in FIG.


6


. The baffle


74


may be fabricated from any number of materials including wax or resin impregnated paper, Styrofoam, plastic sheet or paperboard. The baffle


74


is topped with a bead


76


so that when the baffle


74


is inserted into the container


66


, the rim


72


of the container


66


and the bead


76


of the baffle


74


form a continuous edge


108


to which the lid


80


, depicted in

FIG. 5

, can be sealably attached. When the baffle


74


is inserted into the container


66


, the baffle


74


frictionally seals against the side wall


68


so that neither air nor liquid will leak through the joint


110


. The baffle side


78


is shorter than the container side wall


68


so that a gap


112


is created between the bottom


77


of the baffle


74


and the bottom


79


of the container


66


when the baffle


74


is fully inserted into the container


66


.





FIG. 5

depicts a lid


80


, which covers the container


66


. The lid


80


includes a recessed rim


82


, which releasably attaches to the rim


72


of the container


66


. The lid


80


also includes a grove


84


, which engages the bead


76


of the baffle


74


. When the baffle


74


is inserted into the container


66


, as depicted in

FIG. 6

, and the lid


80


is attached to the baffle/container assembly


106


, as depicted in

FIG. 7

, an air and water tight seal


116


is created between the container


66


and lid


80


and an air and water tight seal


118


is created between the baffle


74


and lid


80


.




The lid


80


includes a tapering annular side wall


90


that extends upwardly from the recessed rim


82


, and a large top wall


98


having a generally circular periphery adjoining the side wall


90


and sloping down to groove


84


. The top wall


98


has an opening


104


adjacent to the periphery of the top wall


98


, which allows vapor to pass through the lid


80


. The lid


80


also includes an annular side wall


88


that extends upward from the recessed rim


82


, and a groove side wall


88


that extends upward from the groove


84


. A small top wall


96


adjoins the side wall


88


and has vent openings


102


near the edge where the small top wall


96


joins the groove side wall


88


. A drink opening top wall


92


adjoins the side wall


86


and has a drink opening


100


. The tapering annular side wall


94


depends downward from the drink opening top wall


92


, and adjoins the small top wall


96


. The side wall


86


, drink opening top wall


92


, and tapered annular side wall


94


are configured to allow the lips of the user to comfortably fit around the area of the drink opening


100


.




The lid is frusto-conical shape (i.e., all angles are less than 90 degrees), which allows it to be constructed of a single piece of vacuum formed plastic and also allows multiple lids to be stacked for storage and shipment.




FIG.


8


through

FIG. 11

depict other alternative embodiments of the present invention. The cup


120


can be any conventional configuration including the common ceramic mug with a handle which is often used for drinking coffee and tea.

FIG. 9

depicts a cup insert


122


, which may be constructed from a single piece of injection molded plastic or from other relatively inexpensive materials such as ceramic, metal, wood, or paper. The cup insert


122


comprises a slopped circular top wall


124


and a vertical baffle member


126


that adjoins the top wall


124


at or near the top wall


124


diameter and extends perpendicularly downward. The outer circular rim


138


and the edges


140


of the baffle


126


frictionally engage the inner side wall of the cup


40


when the cup insert


122


is inserted into the cup


40


to create the cup/insert assembly


136


, as depicted in FIG.


11


. The outer rim


138


of the top wall


124


and edge


140


of the baffle


126


include a gasket or flap


127


which is preferably but not necessarily made out of the same material as the rest of the cup insert


122


but is thinner so as to be more flexible in order to assist in obtaining an air and water tight seal and to allow a single sized cup insert


122


to fit slightly different diameter cups. The sloping circular top wall


124


has a drink notch


130


at the lowest point when the cup insert


122


is inserted into the cup


120


. The top wall


124


also includes vent openings


132


on the same side of the baffle member


126


as the drink notch


130


that are near to where the baffle member


126


joins the top wall


124


. The top wall also includes a vent opening


134


that is on the opposite side of the baffle member


126


from the drink notch


130


. The precise size, shape, location and number of vent openings


132


and


134


may vary depending upon the size and shape of the cup


120


. However, there must always be at least one vent opening


134


, which allows air pressure within the cup


120


to equalize when he cup


120


is tipped to the drinking position and back to the level position. Vent openings should also be located so that the beverage will not spill out of the vent openings when the cup is tipped to the drinking position. The cup insert


122


also includes a tapered side wall


128


which extends upward from the top wall


124


from that portion of the top wall rim that is on the opposite side of the baffle


126


from the drink notch


130


. The rim


142


of the side wall


128


contains a bead or lip which prevents the cup insert


122


from being pushed too far into the cup


120


. As depicted in

FIG. 11

, the rim


142


allows the insert to easily be inserted into and removed from the cup


120


and insures that the cup insert


122


is properly positioned in the cup


120


when the insert


122


is pushed into the cup


120


until the rim


142


rests against the lip of the cup, as shown in FIG.


11


.




The cup insert embodiment


144


depicted in

FIG. 10

is identical to the embodiment


122


depicted in

FIG. 9

except that the vertical portion


146


of the baffle


126


′ is shorter and the baffle


126


′ has a horizontal portion


148


extending in a half circle from the bottom


149


of the vertical portion


146


of baffle


126


′. The edge


150


of the horizontal portion


148


of the baffle frictionally engages the inner side wall


141


of the cup


120


in the same manner as the edges


140


of the vertical portion


146


of the baffle


126


frictionally engage the inner side wall


126


′ of the cup


120


. The horizontal portion


148


of the baffle


126


′ has a notch


152


, which allows air and liquid to pass between the horizontal portion


148


of the baffle


126


′ and the inner side wall


141


of the cup


120


.




FIG.


12


through

FIG. 16

depict yet another important embodiment of the present invention. The container


156


, depicted in

FIG. 12

, is a reusable beverage cup, typically constructed of plastic, or aluminum, or stainless steel. The container


156


has an annular flanged neck


162


which may also include threading or similar features which allow the lid


170


, depicted in

FIG. 14

to be removably attached to the container


156


, in the manner depicted in FIG.


16


. The container


156


includes first


166




1


and second


166




2


grooves


166


on opposing sides of the interior side wall


167


of the container


156


, to create a baffle space of a preselected width and shape. As illustrated, a constant width baffle space W


s


is created such that the baffle


168


of width W


B


fits sealingly between first


166




1


and second


166




2


grooves when inserted into the container


156


, to create a container/baffle assembly


186


, as depicted in FIG.


15


. Thus, the baffle


168


is sized and shaped so that, when the baffle


168


is inserted into the container


156


, an air and water tight seal


188


is created between the side edges


170


of the baffle


168


and the interior side walls


167


of the cup


156


. However, a gap


190


remains between the bottom edge


189


of the baffle


168


and the base


191


of the cup


156


such that liquid my flow freely beneath the baffle


168


. The container


156


also includes a tube


160


attached to the inner side wall of the container


156


, tube


160


extending vertically down the side wall of container


156


. The bottom


161


of tube


160


opens near the base


191


of container


156


and the top


163


of tube


160


opens at the rim of the container


156


.





FIG. 14

depicts a lid


170


that includes a circular top wall


172


and also extends upward from the top wall


172


to create a drinking lip


176


. The top wall


172


contains a drink opening


178


near the periphery of the top wall


172


. The top wall


172


also includes vent openings


180


that are located near the periphery of the top wall


172


approximately 90 degrees from the drink opening


178


and adjacent to where the baffle


168


seals against the bottom of the top wall


172


, when the lid


170


is attached to the baffle/container assembly


186


. The vent openings


180


are on the same side of the baffle


168


as the drink opening


178


. The lid


172


also includes a vent opening


182


which is near the periphery of the top wall


172


approximately 180 degrees from the drink opening


178


. By locating the vent openings


180


and


182


as described above, beverage within the container


156


will not spill out the vent openings when the container


156


is tipped to the drinking position. A curved pipe


184


is attached to the vent opening


182


and extends horizontally on top of the top wall


172


toward the drink opening


178


. This allows vapor to be forced out of the vent opening


182


and to be directed towards the user's nose, when the container


156


is tipped from the drinking position back to the level or vertical position. The vent openings


180


may also be ducted (not shown) to direct vapor as desired.




When the lid


170


is attached to the baffle/container assembly


186


, as depicted in

FIG. 16

, the drink opening


178


aligns with the top


163


of the tube


160


such that, when the lid


170


and container


156


and assembled into a vapor directing beverage container


192


, which contains liquid and is tipped to the drinking position, only the vapor within the tube


160


is forced out the drink opening


178


, thus allowing more vapor to be directed out the vent openings


180


.




FIG.


17


through

FIG. 20

depict yet another embodiment of the present invention. The container


198


depicted in

FIG. 17

is the same as the container


156


depicted in

FIG. 12

, except that container


198


does not have grooves


166


and does not have a tube


160


. The lid


200


is the same as the lid


170


(ducting


184


of the lid is not shown). However, in this alternative embodiment, the vertical baffle


168


is replaced with a baffle chamber


202


, as depicted in FIG.


18


. The baffle chamber


202


includes a curved side wall


204


and a rectangular side wall


206


, both side walls extending upward from a baffle base


208


. The baffle base


208


has an opening


210


which is directly beneath the drink opening


214


when the baffle chamber


202


is sealably attached along reference line location


216


to the lid


200


, as depicted in FIG.


19


.

FIG. 20

depicts the lid/baffle chamber assembly


212


removably attached to the container


198


. When the vapor directing beverage container


218


contains liquid and is tipped to the drinking position, vapor within the baffle chamber


202


is forced out the vent openings


180


and drink opening


214


as liquid flows into the baffle chamber


202


through the baffle base


208


opening


210


.




Attention is now directed to

FIGS. 21-23

, where yet another embodiment of my vapor directing beverage container assembly


300


is depicted. The vapor directing beverage container assembly


300


comprises a container


302


having an opening


304


and a bowl portion


306


for receiving and containing a liquid


308


therein (see FIG.


26


). As shown in

FIG. 26

, the container


302


preferably includes a double walled insulating chamber comprising an outer wall


310


having an inner portion


312


, an inner wall


314


having an outer portion


316


, to provide a chamber


320


between the inner portion


312


of outer wall


310


and the outer portion


316


of the inner wall


314


. The container


302


opening


304


is configured for receiving in suspended relationship within the bowl portion


306


and in a spaced relationship to the inner portion


322


of inner wall


314


an at least partially tubular baffle assembly


330


. The tubular portion


332


of the baffle assembly


330


extends downwardly from the inner surface


334


of lid


336


for a preselected distance X to a lower end portion


337


having a bottom end


338


, so that a relatively small gap G is provided between the bottom end


338


of the baffle assembly


330


and the bottom portion


340


of the inner portion


322


of inner wall


314


of container


302


. For example, in a typical container


302


having an overall exterior height of a little more than about 6 inches, the downwardly extending length X of baffle assembly


330


is about 0.25 inches less than than that of the interior height, or slightly less than about 6 inches, leaving a clearance gap G of about 0.25 inches. In the downwardly extending tubular portion


332


of the baffle assembly


330


, I also prefer that the central wall portion


344


be provided oriented in a plane perpendicular to a reference diameter line


348


of the lid


336


, when the reference diameter line


348


is depicted through the center


352


of liquid outlet


354


(defined by edgewall


356


) in the lid


350


.




I have also developed and disclose herein a baffle structure in which the volume of vapor pumped is controlled by the shape of the baffle outlet, so that a relatively smooth vapor volume curve is provided for various liquid volumes in a container


302


. This is achieved by evaluating the volume pumped at various liquid levels in the container, and by then providing a sliced outlet shape


360


that becomes sealingly effective only at a preselected tilt angle theta (ø) for a preselected liquid level. This is illustrated in

FIG. 27

, where at liquid level L


3


, the container must be tilted an angle theta(ø)


4


before the tubular portion


332


of tubular baffle assembly


330


becomes effective. Then, before liquid becomes available at the liquid outlet


354


, the container


302


must be additionally tilted by a further angle, theta (ø)


3


−theta (ø)


4


, at which time the user can sip liquid L from the outlet


354


. This is important because without the angularly sliced tubular baffle outlet


360


, when liquid levels are low in the container, high vapor volumes would be pumped through the at least one vapor passageways


364


which allow vapor


366


to escape from tubular portion


332


of the tubular baffle assembly


330


.




This design feature is more rigorously evaluated from the selected geometry for a tubular baffle assembly. For a simple case of a tubular baffle assembly of semi-circular cross section having an interior radius R (see FIG.


26


), the volume of vapor pumped when the container


302


is titled is equal to 2/3 R


3


tan Ø, where theta (ø) is the angle between the liquid L surface at rest and the liquid surface L at the point the container


302


reaches an angle wherein liquid L is available at the drink opening outlet


354


. As shown in

FIG. 27

, at liquid level L


1


(i.e, the container is nearly full), the pumped volume in a container having a semi-circular tubular baffle assembly having a one inch radius R, where theta (ø) is 58 degrees, (where pumped volume is the amount of vapor attempting to exit through vapor passageway


364


) is 1.067 cubic inches. Then, at liquid level L


2


, and where theta (ø) is 66 degrees, the pumped vapor volume is 1.497 cubic inches. At L


3


, where theta (ø) is 72 degrees, the vapor volume displaced is 1.493 cubic inches, due to the sliced outlet


360


shape as defined by the end edge portions thereof. In the absence of the sliced outlet shape, the volume displaced would be 2.052 cubic inches. Thus, my sliced tubular portion of the tubular baffle, as defined by an inlet edge portion


37


, allows a more uniform pumping volume to be achieved, when compared to tubular baffle structures wherein all sidewalls of the tubular portion of the baffle extend downward for the same preselected distance.




However, these dimensions are provided by way of example and should not be construed in any way to be a limitation, as many other configurations for the baffle assembly


330


may be utilized to achieve the vapor pumping method taught herein.
