Abstract

A dispenser includes a dock configured to be fixed in place at a use device and a solid product holder configured to be removably secured to the dock. The dock has a first portion including a fixation element that is configured to fix the dock in place at the use device and a second portion including a receiving structure. The solid product holder includes a retaining structure, a base, and a support structure. The retaining structure is configured to removably secure the solid product holder to the receiving structure at the second portion of the dock. The base defines a plurality of apertures that form an open area at which the liquid is received at the solid product holder. The support structure extends from the base and defines an internal volume for holding the solid product at the solid product holder.

First claim

What is claimed is:

1. A dispenser for creating a solution by dissolving a solid product with a liquid, the dispenser comprising:
a dock configured to be fixed in place at a use device that comprises a warewashing machine, the dock having a first portion and a second portion, the first portion including a fixation element that is configured to fix the dock in place at the use device, the second portion including a receiving structure;
a solid product holder configured to be removably secured to the dock, the solid product holder comprising:
a retaining structure configured to removably secure the solid product holder to the receiving structure at the second portion of the dock;
a base defining a plurality of apertures that form an open area at which the liquid is received at the solid product holder, wherein the base comprises a first plate and a second plate, wherein the first plate defines a first set of the plurality of apertures and the second plate defines a second set of the plurality of apertures, and wherein the second plate is movable at the solid product holder relative to the first plate; and
a support structure extending from the base and defining an internal volume for holding the solid product at the solid product holder;

an open area adjustment device that includes a power source, a motor connected to the power source, and a drive member driven by the motor and interfacing with the second plate, wherein the drive member, when driven, is configured to move the second plate relative to the first plate so as to adjust the open area at which the liquid is received at the solid product holder; and
a sensor in communication with the open area adjustment device, the sensor configured to detect a use device condition comprising termination of one operational cycle and initiation of another operational cycle at the warewashing machine, wherein based on the use device condition the sensor is configured to output a signal to cause the open area adjustment device to actuate the motor so that the drive member is driven to adjust the open area at which the liquid is received at the solid product holder.

2. The dispenser of claim 1 , wherein the plurality of apertures are defined across a first cross-sectional area of the base and the internal volume is defined across a second cross-sectional area of the support structure, and wherein the first cross-sectional area approximates the second cross-sectional area.

3. The dispenser of claim 1 , wherein the base is configured to adjust the open area at which the liquid is received at the solid product holder by movement of the second plate relative to the first plate.

4. The dispenser of claim 1 , further comprising:
a timer in communication with the open area adjustment device, wherein the timer is configured to output a signal that causes the open area adjustment device to actuate the motor so that the drive member is driven to adjust the open area at which the liquid is received at the solid product holder.

5. The dispenser of claim 1 , wherein at least one of the dock and the solid product holder comprises a transparent surface.

6. The dispenser of claim 1 , wherein the internal volume is further defined by the base such that the solid product holder is configured to communicate the liquid through the plurality of apertures into the internal volume, and wherein the solid product holder is configured to output the solution at the plurality of apertures.

7. The dispenser of claim 1 , wherein the receiving structure comprises a flange that extends out from the second portion, and wherein the flange forms a track surface at a location on the flange that is spaced from the second portion.

8. The dispenser of claim 7 , wherein the flange forms an opened flange end and a closed flange end, wherein the track surface extends from a first track surface end to a second track surface end, and wherein the first track surface end and the second track surface end are at the opened flange end.

9. The dispenser of claim 8 , wherein the retaining structure of the solid product holder comprises a catch that is configured to sit on the track surface.

10. The dispenser of claim 8 , wherein the receiving structure comprises a locking mechanism at a location along the track surface between the opened flange end and the closed flange end.

11. The dispenser of claim 10 , wherein the locking mechanism is configured to secure the solid product holder to the dock when the retaining structure of the solid product holder is moved along the track surface and past the locking mechanism, and wherein the locking mechanism is configured to unsecure the solid product holder from the dock upon the retaining structure of the solid product holder being brought into contact with the locking mechanism.

12. The dispenser of claim 1 , wherein the receiving structure comprises a protruded lip having a first lip end and a second lip end, wherein the protruded lip extends out from the second portion at the first lip end and forms a receiving surface at the second lip end.

13. The dispenser of claim 12 , wherein the retaining structure of the solid product holder comprises a cam having a first cam end with a retaining surface and a second cam end opposite the first cam end, and wherein the retaining surface at the first cam end is configured to attach to the receiving surface at the second lip end to secure the solid product holder to the dock.

14. The dispenser of claim 13 , wherein the protruded lip includes a frustoconical shape so as to taper in a direction from the second lip end toward the first lip end.

15. The dispenser of claim 14 , wherein the cam has a secured position at which the retaining surface at the first cam end is attached to the receiving surface at the second lip end and a released position at which the retaining surface at the first cam end is off of the receiving surface at the second lip end, wherein the cam is biased to the secured position, and wherein the bias of the cam to the secured position is overcome when the retaining surface at the first cam end is at a location along the frustoconical shape.

16. The dispenser of claim 12 , wherein the support structure comprises a first vertical support rib and a second vertical support rib that is spaced about the base from the first vertical support rib, and wherein the dock comprises a continuous surface that shields that the internal volume for holding the solid product when the solid product holder is secured to the dock.
