Abstract

A beverage quantity indicator is provided for use with beverage containers of a type which do not include a visual or other type of indication of the quantity of beverage remaining in the container. The indicator is incorporated into a beverage stand and includes a weight scale for weighing beverage containers on the stand, thus providing an indication of the quantity of beverage within the container. A preferred form of beverage stand is also disclosed. The weight scale on the stand includes a hinge-mounted plate on which a beverage container rests. The hinge-mounted plate is movable generally vertically along an arcuate path. A spring on the beverage stand urges the hinge-mounted plate generally upwardly and the amount of flexure of the spring indicates the quantity of beverage in the container on the plate. A downward-movement inhibitor is included to prevent excessive downward movement of the scale when downward pressure is exerted on the container, such as when dispensing beverages from an airpot-type dispenser which includes a beverage dispensing pump.

Claims

1. A beverage quantity indicator for use with a beverage stand for supporting a pump-type beverage container which dispenses a beverage contained therein in response to downward pressure on a portion of the container, the beverage quantity indicator comprising:

a weight scale on the stand having a frame for supporting a beverage container thereon, the frame being movable downwardly along an arcuate path when a weight is resting thereon, whereby a beverage container supported on the weight scale will move along an arcuate path together with the frame,

a weight indicator on the stand operatively connected to the scale for indicating the amount of downward movement of the frame, thereby indicating the relative quantity of beverage in a beverage container supported on the weight scale, and

a container-engaging surface supported on the stand above the frame, the container-engaging surface being positioned to contact a portion of a beverage container supported on the frame as it moves downwardly along an arcuate path, which limits the downward arcuate movement of the frame and beverage container when downward pressure is exerted on the beverage container during the dispensing of a beverage therefrom, whereby excessive downward movement of the frame and beverage container is prevented.

2. A beverage quantity indicator as in claim 1 including means on the stand for securing one or more pump-type beverage containers to the stand to prevent unauthorized removal of containers from the stand.

3. A beverage quantity indicator as in claim 2 in which said means for securing includes a positioner on said beverage stand supported above said frame which partially surrounds and positions beverage containers on said beverage stand, and wherein said container-engaging surface is located on said positioner.

4. A beverage quantity indicator as in claim 3 in which said positioner includes a contoured edge which is generally configured to partially surround a beverage container on said beverage stand, said contoured edge including said container-engaging surface thereon.

5. A beverage quantity indicator as in claim 1 in which said movable frame is attached to the beverage stand by means of a hinge which includes a generally horizontal pivot axis, wherein the movement of said frame, and of the beverage container supported thereon, is generally arcuate.

6. A beverage quantity indicator as in claim 5 in which said scale includes a spring functionally interposed between said frame and said beverage stand.

7. A beverage quantity indicator for use with a beverage stand on which a beverage container is supported, the beverage quantity indicator comprising:

a weight scale, including a movable frame for supporting a beverage container thereon and a spring functionally interposed between said frame and said beverage stand, said spring being an elongate resilient member having first and second ends which is attached to the beverage stand adjacent said first end, said second end being movable by flexure of said resilient member, and

a hinge for attaching said movable frame to the beverage stand, the hinge including a generally horizontal pivot axis, wherein the movement of said frame, and of a beverage container supported thereon, is generally arcuate.

8. A beverage quantity indicator as in claim 7 including a beverage stand having said resilient member attached thereto adjacent said first end of said resilient member and having a viewing aperture adjacent said second end of said resilient member for observing the amount of flexure of said resilient member, whereby the observed position of said second end of said resilient member indicates the quantity of beverage in a beverage container supported on said scale.

9. A beverage quantity indicator for use with a beverage stand on which a beverage container is supported, the beverage quantity indicator comprising:

a generally horizontal platform,

a weight scale including a frame movably supported above said platform having top and bottom surfaces and side edges for supporting a beverage container thereon, said frame being attached to said beverage stand by means of a hinge having a generally horizontal pivot axis, said hinge being attached to said frame adjacent a first side edge thereof, whereby the operative movement of said frame generally toward and away from said platform is generally arcuate, and

a spring functionally interposed between said frame and said beverage stand, the weight scale serving to weigh a beverage container on said frame, thereby indicating the relative quantity of beverage in the beverage container.

10. A beverage quantity indicator as in claim 9 in which said spring is in the form of a resilient arm having first and second ends, said spring being attached to said beverage stand below said platform at a location adjacent said first end of said arm, and including a rigid linkage extending downwardly from said frame and contacting said arm at a location spaced apart from the point of attachment of said arm to said beverage stand such that said frame is urged upwardly by said arm and said member.

11. A beverage stand for pump-type beverage containers, the stand being of the type which secures one or more beverage containers to the stand to prevent unauthorized removal thereof, the beverage stand comprising:

a base,

a scale on said base for weighing a beverage container secured thereon,

said scale including a movable frame for supporting a beverage container thereon, the frame being movable downwardly along an arcuate path when a weight is resting thereon, whereby a beverage container supported on the weight scale will move along an arcuate path together with the frame,

a weight indicator, whereby the relative weight of a beverage container on said frame indicates the relative quantity of beverage in the container, and

a container-engaging surface supported on the stand above the frame, the container-engaging surface being positioned to contact a portion of a beverage container supported on the frame as it moves downwardly along an arcuate path, which limits the downward arcuate movement of the frame and beverage container when downward pressure is exerted on the beverage container during the dispensing of a beverage therefrom, whereby excessive downward movement of the pump-type beverage container on said scale is prevented.

14. A beverage stand as in claim 11 in which the position of said movable frame relative to said base changes in response to changes in the weight on said movable frame, and said weight indicator includes a position-responsive display device on the beverage stand responsive to the position of said movable frame, whereby said display device indicates the relative weight on said movable frame of said scale.

15. A beverage stand as in claim 11 in which said container-engaging surface is mounted on a positioner supported on said base above said frame, and said positioner is a member which partially surrounds and engages a beverage container supported on the stand.

16. A beverage stand as in claim 15 in which said positioner includes a contoured edge which is generally configured to partially surround a beverage container on said base, said contoured edge including said container-engaging surface thereon.

12. A beverage stand for indicating the quantity of beverage in a beverage container supported on the stand, comprising:

a base,

a scale on said base for weighing a beverage container thereon,

said scale including a generally horizontal movable frame having a top surface on which a beverage container rests, and side edges along the periphery of said frame,

a hinge for attaching said frame to said base, said hinge being attached to said frame adjacent a side edge thereof, said hinge including a generally horizontal pivot axis, whereby said frame moves generally vertically relative to said beverage stand along an arcuate path,

said scale further including a spring functionally interposed between said frame and said base for urging said frame upwardly, and

a weight indicator for indicating the weight measured by said scale, whereby the relative weight of a beverage container on said scale indicates the relative quantity of beverage in the container.
