Abstract
The present invention is a spill-resistant beverage server ideally suited for pouring beverages aboard airliners in flight. The server utilizes a plurality of small pour openings and a closed top which prevents accidental spillage in the event of rough flying conditions. A thumb actuator lever opens the pour openings when in use and a closing device closes the pour openings when the thumb actuator is released. The server is shaped to provide a low center of gravity, even when the container is full, thereby providing a stable server resistant to tipping. A rubber coating over the handle gives the operator a positive grip and prevents accidental dropping. The server also incorporates an indicator device used to display the type of beverage contained therein.
Description




BACKGROUND OF THE INVENTION




This invention relates generally to a beverage server ideally suited for airline service. More particularly, the present invention relates to a beverage server with a plurality of small pour openings designed to provide a steady, controlled flow when poured and to resist sudden surges of liquid if the container is bumped or jerked. The server has a thumb actuator which can be moved to uncover the pour openings and allow a liquid to be poured. The thumb actuator is biased to return to a closed position when released. The container is shaped to retain a low center of gravity regardless of the quantity of liquid contained therein.




Pouring beverages during a flight presents unique problems. Aircraft often encounter areas of varying air pressure which act on the plane to produce abrupt elevation changes. These pressure differences or turbulence result in a bumpy ride for the passengers of the airplane and makes it difficult to pour beverages such as coffee and tea which are not typically packaged in individual containers. Furthermore, turbulence can act to tip over containers that are simply resting on a service cart.




BRIEF SUMMARY OF THE INVENTION




It is a primary object of this invention to provide a beverage server with a controlled flow rate.




It is another object to provide a beverage server that remains closed when not in use.




It is a further object to provide a beverage server that is stable and resistant to tipping or spilling.




It is another object to provide a beverage server that provides an indicator which indicates the type of beverage contained therein.




The instant invention comprises a beverage server with a plurality of small pour openings which provide a substantially constant flow regardless of whether the container is bumped or jerked while the liquid is being poured. A moveable closing device keeps the pour openings closed when the server is not in use.




As a further beneficial feature, the server is relatively squat to resist tipping and preferably has a rubber coating over the handle to provide the operator with a positive grip.




The closing device may preferably comprise a rotatable ring with a thumb actuator and a plurality of closing elements which are substantially diametrically opposed to the thumb actuator in cooperative juxtaposition to the pour openings. A biasing mechanism, preferably clip springs, ensure that the closing elements cover the pour openings when the beverage server is not being used and the thumb actuator is in its rest or closed position. When the thumb actuator is rotated slightly in either direction, the closing elements are angularly displaced, uncovering the pour openings.




The closing device is advantageously mounted on the top wall of a container in which liquid is held. The aforesaid pour openings are defined by the top wall which also defines a large fill opening.




The container further comprises a handle opposite the pour openings which has a flange extending upwardly therefrom. The thumb actuator extends over the flange and has a hollow bottom side with a downwardly extending skirt which limits the angular distance that the actuator may be rotated by making contact with the flange.




In the disclosed embodiment, an annular cover attaches to the top of the container and covers the ring closing device. Projections extending upwardly from the container and downwardly from the cover act together to provide a guide path within which the ring may rotate. The cover also defines a fill opening within which a lid may be removably received to form a watertight seal. Vent holes penetrate the top of the cover and provide a path for air to travel to replace the liquid being dispensed from the container and ensure a smooth pour. The cover and the container both have forwardly extending, vertically aligned lips which together form a pour spout adjacent the pour openings.

20


and is attached thereto. The cover


60


has a cylindrical wall


74


which defines a circular fill hole


70


located directly above and substantially concentric with the fill opening


34


of the container


20


. The cylindrical wall


74


preferably has thread elements


68


projecting inwardly therefrom. The cover


60


also has an upper lip


62


which projects outwardly proximate the front


26


of the container


20


and conforms to the lower lip


38


thereof The lower lip


38


abuts with the upper lip


62


to form a pour spout


12


. The cover


60


further has downwardly extending cover projections


72


which align vertically with the container projections


46


to form a recessed guide path


76


in which the actuator ring


50


rests and rotates as most clearly shown in

FIGS. 2 and 3

. Preferably, curved posts


64


extend downwardly from inside the cover


60


to provide surfaces against which the clip springs


56


of the ring


50


act to return the ring


50


to the normal position such that the valve elements


52


cover the pour openings


36


. An opening


65


is formed through the rear side of annular cover


60


for the extension of actuating arm


54


therethrough. Finally, the cover may have air vents


66


which provide a path for air to flow from outside the server


10


, through the air vents


66


, through the air holes


40


, into the container


20


.




A lid


80


is used to close the fill hole


70


of the cover


60


. The lid


80


is circular and forms a watertight seal with the cylindrical wall


74


of the cover


60


when placed therein. For that purpose, lid


80


is formed to include a peripheral top lip


88


which seats as shown in

FIG. 3

on the shoulder


63


formed at the top of cylindrical wall


74


. In a preferred embodiment, the lid


80


has threads


82


that mate with the threads


68


of the cover


60


. The lid


80


may have a grip


86


extending upwardly therefrom to provide a place for an operator to grasp when removing or replacing the lid


80


. When the lid is screwed into place as shown in

FIG. 3

, its top lip


88


is drawn down tight against shoulder


63


, and its lower rim


90


abuts against shoulder


35


of container top wall


30


. It is envisioned that an indicator flag


84


is slidably attached to the grip


86


such that the flag


84


has a plurality of positions, each signaling the type of beverage which is contained within the server


10


.




In operation of the preferred embodiment, the operator grasps the handle


42


such that the operator's thumb rests on one of the thumb rest areas


55




a


or


55




b,


depending on which hand is used to lift the server


10


. The operator then rotates the thumb actuator


54


in either a clockwise or counterclockwise direction, as indicated by the directional arrows in

FIG. 2

, until the actuator


54


is stopped by the skirt


58


abutting against the flange


44


of the handle


42


. This action rotates the ring


50


the proper amount to optimally move the valve elements


52


, uncovering the pour openings


36


, and also compresses the clip springs


56


against the posts


64


. The operator then tips the server


10


forward, allowing the liquid in the container


20


to flow through the pour openings


36


, around the valve elements


52


, and out the pour spout


12


. As the liquid flows out of the container


20


, air is sucked in through the air vents


66


, then through the air holes


40


, and into the container


20


.




When the operator is finished, the thumb actuator


54


is released. The clip springs


56


expand against the posts


64


and cause the ring


50


to rotate back to its normal position such that the valve elements


52


cover the pour openings


36


and reestablish a watertight seal therebetween.




In order to ensure a stable server


10


. The server


10


has dimensions which maintain a low center of gravity regardless of the quantity of liquid stored in the container


20


. It is envisioned that the server be of any size. However, it is preferred that the height


14


be no more than fifty percent greater than the lesser dimension of width


16


and length


18


.
