Abstract

A beverage container washing system may be used for rapid washing and/or sanitizing of beverage containers, e.g., for use in a retail environment to wash and/or sanitize customer-provided beverage containers prior to filling the beverage containers with purchased beverages, among other applications. The beverage container washing system may include multiple concentric housing members supported on a base, with each having one or more openings that may be selectively aligned through driven movement of at least one of the concentric housing members to provide access to a wash chamber.

First claim

What is claimed is:

1. An apparatus for washing a beverage container, comprising:
a stationary base;
inner and outer concentric housing members supported on the stationary base, the inner concentric housing member being disposed inwardly from the outer concentric housing member and forming at least a portion of a wash chamber with the stationary base, each of the inner and outer concentric housing members including an opening;
a holder disposed within the wash chamber and configured to hold the beverage container during a washing operation; and
a drive assembly coupled to the inner concentric housing member and configured to rotate the inner concentric housing member about an axis of rotation between first and second relative positions, wherein when in the first relative position, the respective openings of the inner and outer concentric housing members are aligned to permit external access to the holder in the wash chamber and when in the second relative position, the respective openings of the inner and outer concentric housing members are unaligned to restrict external access to the holder in the wash chamber during the washing operation;
wherein the holder is positioned to hold the beverage container substantially along the axis of rotation during the washing operation, wherein the drive assembly includes an electric motor and a first gear, and wherein the inner concentric housing member includes a second gear circumscribing a perimeter of the inner concentric housing member and engaging the first gear.

2. The apparatus of claim 1 , wherein each of the inner and outer concentric housing members fully circumscribe the axis of rotation.

3. The apparatus of claim 1 , wherein when in the first relative position, the respective openings of the inner and outer concentric housing members permit external access to the holder in the wash chamber from a first location, wherein one of the inner and outer concentric housing members includes a second opening, and wherein the drive assembly is further configured to rotate the inner concentric housing member to a third relative position that provides external access to the holder in the wash chamber through the second opening and from a second location that is different from the first location.

4. The apparatus of claim 3 , wherein the first and second locations are on opposite sides of the apparatus such that the beverage container may be placed within the wash chamber from the first location and removed from the wash chamber from the second location.

5. The apparatus of claim 1 , wherein the drive assembly is configured to rotate the inner concentric housing member by rotating only the inner concentric housing member while the outer concentric housing member remains stationary.

6. The apparatus of claim 1 , wherein the inner concentric housing member comprises an inner concentric dome and the outer concentric housing member comprises an outer concentric dome.

7. The apparatus of claim 6 , wherein the opening of the outer concentric dome is an entrance opening, wherein the outer concentric dome includes an exit opening disposed on an opposite side of the outer concentric dome from the entrance opening, and wherein the drive assembly is configured to rotate the inner concentric dome to the first relative position prior to the washing operation to align the opening of the inner concentric dome with the entrance opening to permit insertion of the beverage container into the holder in the wash chamber, to rotate the inner concentric dome to the second relative position proximate a start of the washing operation to inhibit wash fluid sprayed during the washing operation from exiting through the entrance and exit openings of the outer concentric dome, and to rotate the inner concentric dome to a third relative position proximate an end of the washing operation to align the opening of the inner concentric dome with the exit opening to permit removal of the beverage container from the holder in the wash chamber.

8. The apparatus of claim 6 , wherein the opening of the outer concentric dome is an entrance opening, wherein the outer concentric dome includes an exit opening disposed on an opposite side of the outer concentric dome from the entrance opening, wherein the opening in the inner concentric dome is a first opening and the inner concentric dome includes a second opening disposed on an opposite side of the inner concentric dome from the first opening, and wherein the drive assembly is configured to rotate the inner concentric dome to the first relative position prior to the washing operation to align one of the first and second openings of the inner concentric dome with the entrance opening to permit insertion of the beverage container into the holder in the wash chamber, to rotate the inner concentric dome to the second relative position proximate a start of the washing operation to inhibit wash fluid sprayed during the washing operation from exiting through the entrance and exit openings of the outer concentric dome, and to rotate the inner concentric dome to a third relative position proximate an end of the washing operation to align one of the first and second openings of the inner concentric dome with the exit opening to permit removal of the beverage container from the holder in the wash chamber.

9. The apparatus of claim 6 , wherein the holder is disposed in a fixed location within the wash chamber and the stationary base includes a fixed collector configured to collect the wash fluid sprayed during the washing operation.

10. The apparatus of claim 9 , further comprising a spray assembly including at least one sprayer disposed within the wash chamber and configured to spray the wash fluid onto the beverage container while the beverage container is held by the holder, wherein the at least one sprayer is supported by the stationary base.

11. The apparatus of claim 6 , further comprising an ultraviolet sanitizing assembly including at least one ultraviolet light disposed within the wash chamber and configured to emit ultraviolet light toward the beverage container while the beverage container is held by the holder.

12. The apparatus of claim 11 , wherein the at least one ultraviolet light is supported by and rotatable with the inner concentric dome.

13. The apparatus of claim 11 , wherein the at least one ultraviolet light is stationary and supported by the outer concentric dome.

14. The apparatus of claim 6 , further comprising a dryer assembly including at least one air outlet disposed in the inner concentric dome and configured to blow air onto the beverage container while the beverage container is held by the holder.

15. The apparatus of claim 1 , further comprising:
a position detector configured to detect one or more relative positions between the inner and outer concentric housing members about the axis of rotation; and
a controller coupled to the drive assembly and the position detector and configured to control the drive assembly to rotate the at least one of the inner and outer concentric housing members between the first and second relative positions based at least in part on an output of the position detector.

16. An apparatus for washing a beverage container, comprising:
a base;
inner and outer concentric housing members supported on the base, the inner concentric housing member being disposed inwardly from the outer concentric housing member and forming at least a portion of a wash chamber, each of the inner and outer concentric housing members including an opening;
a holder disposed within the wash chamber and configured to hold the beverage containe
