Abstract
Abstract A liquid dispenser, for dispensing discreet amounts of a liquid, such as a mouthwash, comprised of a container for a supply of a liquid and a base member which may be attached to the container in a horizontal position to provide for a free standing condition of the assembly, or, in a vertical position for suspension from a pair of screws preset in a wall. A double acting valve, provided with a laterally extending release bar, is disposed at the bottom of the container, said valve being normally spring urged into a closing relation with a discharge port in the bottom of a dose cup, fixed relative to the bottom end of the container. When the top edge of a receptacle such as a drinking glass or paper cup is pressed upwardly against the release bar, the valve is moved from the discharge port of the dose cup permitting the liquid therein to flow into the drinking glass or other receptacle, and the valve is moved into a closing relation with a discharge port opening from the container into the dose cup. When the glass or other receptacle is removed from the release bar, the dose cup port is again closed and the container port is reopened to replenish the dose cup with a discreet amount of liquid from the container.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
355 words
A liquid dispenser comprising a container including an inner chamber for the reception of a quantity of a liquid to be dispensed and having an open upper end with a removable lid, a base for supporting said container, a support post connecting between said base and container with a bottom end of said container positioned a predetermined distance above said base, a dose cup positioned beneath said bottom end, means to removably fix said dose cup relative to said bottom end, a double acting valve means, spring loaded to a normal first position and including means to move said valve means to a second position, a first discharge port in a bottom portion of said dose cup normally closed by said valve means in said first position, a second discharge port, spaced above said first discharge port, in a bottom end of said container and positioned a predetermined distance downwardly within a chamber defined in said dose cup said second port normally being open to permit a charge of liquid from said container to flow into said dose cup to a depth determined by a spaced position of said second discharge port above said dose cup bottom portion, said means to move being operable by a top edge of a receptacle, such as one of a glass and paper cup when said receptacle is positioned beneath said first discharge port and is pressed upwardly opening said valve means relative to said first discharge port to cause the charge of liquid in said dose cup to flow into said receptacle and to simultaneously close said second discharge port until the receptacle is removed whereupon said valve means returns to a normal closed relation with said first discharge port and to an open relation with said second discharge port to recharge said dose cup from said container, said double acting valve comprising a release bar including a drop center portion spanning said dose cup chamber, and lower and upper valve members fixed to said drop center portion in axial alignment respectively with said first and second ports for alternate movement into and out of closing engagement therewith.
Claim 2
Dependent Claim
355 words
A liquid dispenser comprising a container including an inner chamber for the reception of a quantity of a liquid to be dispensed and having an open upper end with a removable lid, a base for supporting said container, a support post connecting between said base and container with a bottom end of said container positioned a predetermined distance above said base, a dose cup positioned beneath said bottom end, means to removably fix said dose cup relative to said bottom end, a double acting valve means, spring loaded to a normal first position and including means to move said valve means to a second position, a first discharge port in a bottom portion of said dose cup normally closed by said valve means in said first position, a second discharge port, spaced above said first discharge port, in a bottom end of said container and positioned a predetermined distance downwardly within a chamber defined in said dose cup said second port normally being open to permit a charge of liquid from said container to flow into said dose cup to a depth determined by a spaced position of said second discharge port above said dose cup bottom portion, said means to move being operable by a top edge of a receptacle, such as one of a glass and paper cup when said receptacle is positioned beneath said first discharge port and is pressed upwardly opening said valve means relative to said first discharge port to cause the charge of liquid in said dose cup to flow into said receptacle and to simultaneously close said second discharge port until the receptacle is removed whereupon said valve means returns to a normal closed relation with said first discharge port and to an open relation with said second discharge port to recharge said dose cup from said container, said double acting valve comprising a release bar including a drop center portion spanning said dose cup chamber, and lower and upper valve members fixed to said drop center portion in axial alignment respectively with said first and second ports for alternate movement into and out of closing engagement therewith.
Claim 3
Dependent Claim
42 words
The liquid dispenser defined in claim 1 wherein said means to move comprises a pair of opposed wing entensions from said release bar, extending outwardly of said dose cup through respective slots in an upper peripheral edge portion of said dose cup.
Claim 4
Dependent Claim
56 words
The liquid dispenser as defined in claim 1 and including wherein said spring loading of the double acting valve comprises a compression spring disposed between closed outer ends of each pair of at least two pairs of telescopic tube members, extending respectively upwardly and downwardly from said release bar and a bottom portion of said container.
Claim 5
Dependent Claim
87 words
The liquid dispenser as defined in claim 1 wherein the base for supporting the container is configurated to provide a hole through the rear side edge of the base for reception of the support post connecting between the container and the base for reception of said post lower end, and including at least two apertures formed through a bottom face thereof, configurated to engage over the head portions of a pair of screws, preset in a vertical wall to support said base in a generally vertical position.
