Abstract
To dispose wine expectorant from a spit bucket, the interior of a portable pressurizable rigid tank is connected to a vacuum pump which draws a vacuum in the tank. The tank is disconnected from the pump and transported to the spit bucket. An inlet end of a suction conduit connected to the tank is inserted into the spit bucket. A passage from the inlet end to the tank interior is opened to cause the vacuum in the tank to draw-in the wine expectorant from the spit bucket. The tank is taken to a discharge station, and a drain of the tank is opened in order to discharge the tank contents.
Description




BACKGROUND OF THE INVENTION




The present invention relates to a wine expectorant disposal method and apparatus. In particular, the invention relates to a portable pumpless vacuum apparatus and method of use.




At a wine-tasting event, where people sample numerous wines, it is necessary for the tasters to spit-out the samples in order to be able to taste numerous wines without being overcome by the effects of alcohol. At large events of this type, there are many tables at which wine is tasted, each table having its own spit bucket. When full, the spit-buckets are carried to a disposal station and emptied. This is an unpleasant task, requiring that handlers maneuver through a crowd, while trying not to spill the contents of the bucket onto any patrons of the event.




It would be desirable to enable spit buckets to be emptied in a less unpleasant and more sanitary way.




SUMMARY OF THE INVENTION




One aspect of the present invention relates to a portable, pumpless wine expectorant vacuum device which comprises a pressurizable rigid tank having a valved vacuum access adapted to be connected to a separate suction pump for drawing a vacuum in the tank. A valve suction conduit is connected to the tank for enabling wine expectorant to be sucked into the tank by the vacuum. A valved drain is disposed on the tank for emptying the tank.




Preferably, a vacuum conduit communicates with the vacuum access and includes a one way valve exposed at a free end thereof for connection with the suction pump. Also, it is preferred that the drain be disposed at a lower portion of the tank, and that a discharge hose be connected to the drain.




Another aspect of the invention relates to a method of disposing wine expectorant from a spit bucket. The method comprises the steps of:




A) connecting an interior of a portable pressurizable rigid tank to a vacuum pump and actuating the pump for drawing a vacuum in the tank;




B) disconnecting the tank from the pump;




C) transporting the tank away from the pump and to the spit bucket;




D) inserting into the spit bucket an inlet end of a suction conduit connected to the tank and opening a passage from the inlet end to the tank interior to cause the vacuum in the tank to draw-in wine expectorant from the spit bucket; and




E) transporting the tank to a discharge station and opening a drain of the tank to discharge the contents of the tank.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION




Depicted in

FIG. 1

is an expectorant disposal system which includes a portable, pumpless vacuum device


10


and a separate vacuum pump


12


. The vacuum device


10


comprises a rigid tank


14


which is pressurizable, i.e. pressurizable to a negative pressure. The tank


14


has a T-fitting


16


disposed at it upper end, and a drain valve


18


disposed its lower end.




The fitting forms three ports


20


,


22


,


24


. A first of the ports


20


communicates with an interior of the tank


14


, and second and third ones


22


,


24


of the ports communicate with the first port


20


.




A flexible suction conduit


26


includes a suction hose


28


connected to the second port


22


, a manually actuable valve


30


at a free end of the hose


28


, and a relatively stiff wand


32


connected to the valve


30


.




A vacuum conduit


40


includes a vacuum hose


42


connected the third port


24


, and a conventional one-way valve


44


disposed at a free end of the hose


42


.




The vacuum pump


12


includes a hose


50


carrying a fitting


52


at a free end thereof. The fitting


52


comprises a conventional male element which can be connected to the one-way valve


44


to automatically open the valve


44


(which valve


44


is automatically closed when not connected to the fitting


52


).




A drain conduit


60


is connected to the drain valve


18


.




In use at a wine tasting event, the tank


14


is transported to the vacuum pump


12


. For example, the tank could be mounted on a harness


70


capable of being worn on a user's back as shown in FIG.


2


. The user connects the valve


44


to the fitting


52


of the hose


50


, whereupon the valve


44


is opened, enabling the vacuum pump to be activated to draw a vacuum in the tank (e.g. 30 inches of mercury). The valves


18


and


30


are closed at this time.




Then, the tank is disconnected from the pump


12


, whereupon the valve


44


automatically closes, and the tank is transported to a series of expectorant vessels or spit buckets


80


. The user inserts the wand


32


into a first spit bucket


80


and then opens the valve


30


, enabling the tank vacuum to draw expectorant into the tank, as shown in FIG.


2


. The tank can be sized to hold any desired amount of liquid that can be conveniently carried by the user, e.g., three gallons.




Then the tank can be transported to one or more additional spit buckets where the suction procedure is repeated. Once full of liquid, the tank is carried to a disposal station, as shown in

FIG. 4

, whereupon the drain valve


18


is opened to enable liquid to drain from the tank through the drain conduit


60


.




It will be appreciated that the invention eliminates the need to manually carry spit-buckets through a crowd at a wine-tasting event. Attention is directed to the fact that portable vacuum pump units have been proposed which include an electrically driven pump (e.g., see U.S. Pat. Nos. 3,331,090; 5,134,994; and 5,142,730) which are of increased weight due to the presence of the pump. The pumps can be connected to a remote electric source by a cord, thereby having a restricted range of use. Alternatively, the pump can be battery-operated, thereby being even heavier and more expensive. Those shortcomings are all avoided by the present invention.




It will also be appreciated that the valves that are used in the present invention can be of any suitable type. Note that while the vacuum


40


conduit provides the convenience of enabling a user to easily connect the tank to the vacuum pump while wearing the tank, the conduit


40


could be eliminated if the hose


50


were connected directly to the port


24


. Also, the drain conduit


60


could be eliminated if it is preferred to position the valve


18


directly over a drain when opening the valve. The hoses


28


,


42


need not be connected to the tank by way of a fitting


16


; instead, those hoses could be separately connected to the tank.




Although the present invention has been described in connection with preferred embodiments thereof, it will be appreciated by those skilled in the art that additions, deletions, modifications, and substitutions not specifically described may be made without departing from the spirit and scope of the invention as defined in the appended claims.
