Abstract

A multi-station liquid mixing and dispensing apparatus. The apparatus includes a housing that defines a first pocket for supporting a first container, a second pocket for supporting a second container, and a third pocket disposed vertically above at least one of the first pocket and the second pocket. The apparatus also includes a first door pivotably coupled to the housing and enclosing the first pocket, and a second door pivotably coupled to the housing and enclosing the second pocket. The apparatus also includes a valve coupled to the housing to control flow of chemical concentrate to at least one of the first container and the second container.

Claims

1. A multi-station liquid mixing and dispensing apparatus comprising:

a housing at least partially defining a first pocket configured to support a first container, a second pocket configured to support a second container, and a third pocket disposed vertically above at least one of the first pocket and the second pocket;

a first door pivotably coupled to the housing and movable between an opened position in which the first container can be inserted within the first pocket, and a closed position in which the first pocket is substantially closed;

a second door pivotably coupled to the housing and movable from an opened position in which the second container can be inserted within the second pocket, and a closed position in which the second pocket is substantially closed; and

a valve coupled to the housing, the valve operable by a user to select which of the first and second containers from which to dispense chemical concentrate.

2. The multi-station liquid mixing and dispensing apparatus of claim 1, wherein the housing further includes a central support section located between the first door and the second door, and a latch to secure the first door in the closed position of the first door.

3. The multi-station liquid mixing and dispensing apparatus of claim 1, further comprising:

an additional pocket at least partially defined by the housing and configured to receive a third container; and

a fluid line extending to the additional pocket for fluid dispense into the third container, the fluid line receiving fluid including chemical concentrate from at least one of the first and second containers.

4. The multi-station liquid mixing and dispensing apparatus of claim 1, further comprising:

an eductor providing a flow rate of fluid drawing chemical concentrate from at least one of the first container and the second container, and

a hinged panel providing access to the eductor.

5. The multi-station liquid mixing and dispensing apparatus of claim 1, wherein the valve is operable by a user-manipulatable control having an indicator, the indicator movable by movement of the user-manipulatable control to different positions each pointing generally toward the container from which chemical concentrate is dispensed in the corresponding position of the valve.

6. The multi-station liquid mixing and dispensing apparatus of claim 1, wherein the housing has a bottom panel at least partially defined by an outwardly curved profile, and wherein each of the first door and the second door is curved to substantially match the outwardly curved profile of the bottom panel.

7. The multi-station liquid mixing and dispensing apparatus of claim 6, wherein each of the first window and the second window is positioned and dimensioned to permit user identification of:

i) the presence or absence of the first and second containers in the first and second pockets, respectively; and

ii) the level of liquid in the first and second containers in those containers enabling identification of the same.

8. The multi-station liquid mixing and dispensing apparatus of claim 1, wherein:

the housing has a bottom panel at least partially defined by an outwardly curved profile; and

each of the first door and the second door is curved to substantially match the outwardly curved profile of the bottom panel.

9. A multi-station liquid mixing and dispensing apparatus comprising:

a housing defining a first pocket configured to support a first container, a second pocket configured to support a second container, and a third pocket located vertically above one or both of the first pocket and the second pocket;

a door pivotably coupled to the housing and movable from an opened position and a closed position to selectively enclose at least one of the first pocket and the second pocket; and

a valve coupled to the housing, the valve operable by a user to select which of the first and second containers from which to dispense chemical concentrate.

10. The multi-station liquid mixing and dispensing apparatus of claim 9, wherein the housing further includes a central support section located between the first door and the second door, and a latch to secure the first door in the closed position of the first door.

11. The multi-station liquid mixing and dispensing apparatus of claim 9, further comprising:

an eductor providing a flow rate of fluid drawing chemical concentrate from at least one of the first container and the second container, and

a hinged panel providing access to the eductor.

12. The multi-station liquid mixing and dispensing apparatus of claim 11, wherein the hinged panel is located between and partially covered by the first door and the second door.

13. The multi-station liquid mixing and dispensing apparatus of claim 9, wherein the valve is operable by a user-manipulatable control having an indicator, the indicator movable by movement of the user-manipulatable control to different positions each pointing generally toward the container from which chemical concentrate is dispensed in the corresponding position of the valve.

14. The multi-station liquid mixing and dispensing apparatus of claim 9, wherein the first door includes a first window through which the first container can be identified, and wherein the second door includes a second window through which the second container can be identified.

15. The multi-station liquid mixing and dispensing apparatus of claim 14, wherein each of the first window and the second window is positioned and dimensioned to permit user identification of:

i) the presence or absence of the first and second containers in the first and second pockets, respectively; and

ii) the level of liquid in the first and second containers in those containers enabling identification of the same.

16. The multi-station liquid mixing and dispensing apparatus of claim 9, further comprising:

an additional pocket at least partially defined by the housing and configured to receive a third container; and

a fluid line extending to the additional pocket for fluid dispense into the third container, the fluid line receiving fluid including chemical concentrate from at least one of the first and second containers.

17. A multi-station liquid mixing and dispensing apparatus comprising:

a housing at least partially defining a first pocket configured to support a first container, a second pocket configured to support a second container, and a third pocket configured to support a third container, the third pocket and one of the first pocket and the second pocket intersected by a vertical plane;

a first door pivotably coupled to the housing and movable from an opened position in which the first container can be inserted within the first pocket, and a closed position in which the first pocket is substantially closed;

a second door pivotably coupled to the housing and movable from an opened position in which the second container can be inserted within the second pocket, and a closed position in which the second pocket is substantially closed; and

a valve coupled to the housing, the valve operable by a user to select which of the first and second containers from which to dispense chemical concentrate.

18. The multi-station liquid mixing and dispensing apparatus of claim 17, wherein the first door includes a first window through which the first container can be identified, and wherein the second door includes a second window through which the second container can be identified.

19. The multi-station liquid mixing and dispensing apparatus of claim 18, wherein each of the first window and the second window is positioned and dimensioned to permit user identification of:

i) the presence or absence of the first and second containers in the first and second pockets, respectively; and

ii) the level of liquid in the first and second containers in those containers enabling identification of the same.

20. The multi-station liquid mixing and dispensing apparatus of claim 17, wherein:
