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.
