## Title
Docking station for a liquid container

## Abstract

A docking station for use with a liquid container which supports the container in a convenient fixed location. The docking station is designed to accept a liquid container having a predetermined height and diameter. The docking station includes a cam operated actuator which is movable between an upper “open” position to a lower “closed” position. When the actuator is moved to its lower closed position, the actuator opens a valve in the liquid container to permit liquid to be drawn from the container. When the actuator is in its upper position, the valve in the container is closed.

## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a docking station for a liquid container and more particularly to a docking station for a liquid container which is adapted to receive a liquid container such as a bottle or the like containing liquids with the docking station being adapted to accept only bottles of a particular height and diameter to ensure that the proper liquid will be dispensed to a mixing machine, spray nozzle, etc.
2. Description of the Related Art
Corrosive liquid chemicals are typically contained in a container such as a bottle or the like and are frequently dispensed therefrom to a mixing machine, spray nozzle, etc. Normally, a cap is placed on the bottle with a dip tube extending therefrom downwardly into the interior of the bottle for drawing the liquid upwardly thereinto. Normally, a dispensing tube extends from the cap to a mixing machine or to some other piece of equipment which creates suction in the dispensing tube to draw the liquid from the interior of the bottle.
Applicant has previously provided several liquid dispensing systems wherein a throat plug assembly including a valve is positioned in the throat of the bottle with the valve normally being closed but which is opened upon the attachment of a dispensing cap mounted on the upper end of the bottle. Normally, a dispensing tube extends from the dispensing cap to the spray nozzle or to an on-off valve to enable the contents from the bottle to be introduced into a spray bottle or the like. Heretofore, there has not been a convenient means for supporting the bottle during the use thereof. Further, in some cases, the wrong bottle was connected to the spray nozzle or on-off valve which resulted in the wrong chemicals being supplied thereto.
SUMMARY OF THE INVENTION
A docking station is provided for a liquid container which normally has corrosive liquids therein which may be used for cleaning purposes or the like. The liquid container has upper and lower ends and has a hollow throat extending upwardly therefrom which has interior and exterior surfaces. A throat plug assembly, having upper and lower ends, is positioned in the throat of the container to selectively close the hollow throat. The throat plug assembly includes a movable valve, having inlet and discharge sides, which is movable between an upper closed position to a lower open position. The valve, when in its lower open position, permits the flow of liquid therethrough. The valve, when its upper closed position, prevents the flow of liquid therethrough. A dip tube extends downwardly from the inlet side of the valve into the liquid container. The liquid container is placed in the docking station of this invention with the docking station adapted to receive a bottle of a particular height and diameter to ensure that only the proper bottle is received thereby. The docking station has a manually movable actuator mounted at the upper end thereof which is movable between an upper position to a lower position. The actuator has a lower liquid inlet end and an upper liquid discharge end. The upper liquid discharge end has a discharge tube extending therefrom. The lower liquid inlet end of the actuator is in physical engagement with the discharge side of the valve and is in fluid communication therewith, when the actuator is in its lower open position to open the valve so that liquid in the container may pass upwardly through the dip tube, through the valve, through the actuator and outwardly through the discharge tube. The valve is closed when the actuator is in its upper position. The actuator is moved between its upper and lower positions by means of a cam assembly.
It is therefore a principal object of the invention to provide a docking station for a liquid container.
A further object of the invention is to provide a docking station for a liquid container which is adapted to receive a liquid container of a predetermined height and diameter.
A further object of the invention is to provide a docking station for a liquid container which is convenient and safe to use.
Yet another object of the invention is to provide a docking station for a liquid container which may be secured to a vertically disposed support surface.
These and other objects will be obvious to those skilled in the art.

DETAILED DESCRIPTION OF THE INVENTION
In the drawings, the numeral 10 refers to a liquid container having a hollow throat 12 extending upwardly therefrom which has an externally threaded surface 14 and an interior surface 16. A throat plug assembly 18 is press-fitted into throat 12 and is closely similar to the throat plug assembly disclosed in U.S. Pat. No. 5,988,456 which issued Nov. 23, 1999. Assembly 18 includes a tapered cup-shaped plug 20 which is inserted into the throat 12. Assembly 18 also includes a valve stem 22 having a normally closed valve 24 vertically movably mounted therein. Valve 24 is normally maintained in its upper closed position of FIG. 3 by a spring (not shown). When valve 24 is moved to its lower open position, liquid may pass upwardly therethrough in the manner disclosed in U.S. Pat. No. 5,988,456. Dip tube 26 extends downwardly from plug 20 into container 10 to supply liquid to the inlet side of valve 24 as in the '456 patent.
The numeral 28 refers to the docking station of this invention which is adapted to receive a liquid container having a predetermined height and outside diameter. Docking station 28 includes a bracket or support 30 having a lower end 32, upper end 34, back side 36 and an open front side 38 defined by side walls 40 and 42. Bracket 30 may be secured to a wall or the like by extending screws or the like through the openings 44 formed in back side 36.
An actuator assembly 46 is positioned at the upper end of support 30 and is partially enclosed in a hollow hood 48. The front wall 50 of hood 48 is provided with a cam surface 52 including a horizontally disposed portion 54 at the upper end thereof, an inclined portion 56 extending downwardly from portion 54, and a horizontally disposed portion 58. The word “OPEN” is provided on front wall 50 of hood 48 as is the word “CLOSED”.
Actuator assembly 46 includes a cam block 60 positioned on top of upper end 34 of support 30. Cam block 60 is provided with a semi-circular wall member 62 having a cam surface 64 at its upper end which has an upper end 66 and a lower end 68. An upstanding stop 70 is positioned at the lower end 68 of cam surface 64. A rotatable actuator support 72 is mounted within hood 48, as seen in the drawings. Actuator support 72 includes an outer cylindrical wall 74 having a cut-out portion 76 formed therein at the lower end thereof which extends approximately half way around the support 72. The interior of support 72 has a cam surface 78 formed therein which rides upon the cam surface 64. Actuator lever 80 extends outwardly from actuator support 72 and includes a horizontal portion 82 which engages the underside of cam surface 52.
Actuator 84 has its upper end rotatably received by the central opening 86 in actuator support 72 and is maintained therein by a hollow connector 88 having a nipple 90 extending upwardly therefrom. Actuator 84 includes a hollow tubular member 92 positioned therein, the lower end of which is adapted to engage the upper end of valve 24, as will be described hereinafter. The upper end of tubular member 92 is in fluid communication with the interior of connector 88 and nipple 90. Support 94 is secured to the upper end of hood 48 at the inside thereof to aid in attaching hood 48 to actuator support 72 which is attached to cam block 60 which is secured to bracket 30 by screws or the like. The upper end of hood 48 is provided with an opening 96 through which extends a discharge hose or tube 98 which is mounted on nipple 90. Preferably, a disc-shaped support 100 is positioned on the interior lower end 32 of bracket 30 to support the container 10 thereon.
The distance between the upper end of support 100 and the lower end of the actuator 84 is predetermined so that only a bottle or container having a predetermined height may be positioned therebetween to ensure that a bottle or container having the proper liquid therein may be utilized in the docking station. Further, the distance between the edges of side walls 40 and 42 is such that a bottle or container having a predetermined diameter will be received therebetween. Additionally, it is preferred that a conventional cabinet lock (not shown) be positioned in hood 48 so that the cam mechanism may be selectively locked in its upper open position.
The normal method of using the docking station 28 will now be described. The station 28 is secured to a vertical supporting surface such as a wall by screws, as previously described. Actuator lever 80 is moved to its open position (FIG. 5) so that horizontal portion 82 engages the portion 54 of cam surface 52 so that lever 80 yieldably remains in the open position. With the lever 80 in its open position, the actuator 84 is in its upper position (FIG. 5).
A bottle 10 of predetermined height and diameter is placed in the docking station with the valve 24 being in its closed position. When it is desired to dispense liquid from the bottle 10, the lever 80 is moved from its “open” position of FIG. 5 to its “closed” position of FIG. 6. As lever 80 is moved as described, the interaction of cam surfaces 64 and 78 causes tubular member 92 of actuator 84 to be moved downwardly into engagement with valve 24 to move valve 24 downwardly to its open position. The liquid in the bottle 10 may then be drawn upwardly through the dip tube 26, through valve 24, through tubular member 92, through nipple 90, and outwardly through tube 98 to a mixing machine, spray nozzle, on-off valve or the like.
When it is desired to close the valve 24, the lever 80 is moved from its “closed” position of FIG. 6 to its “open” position of FIG. 5 thereby causing tubular member 92 to move upwardly so that valve 24 closes. Thus it can be seen that a unique docking station has been provided to provide a convenient means for supporting a liquid container therein.
Thus it can be seen that the invention accomplishes at least all of its stated objectives.
