Abstract

A sample dispenser includes a dosing unit, a cradle assembly, and tubing connecting the dosing unit and the cradle assembly. The dosing unit is configured to dispense sampling amounts of a flowable substance and includes a nozzle and a mechanical pump communicating with the nozzle. The cradle assembly includes a priming cradle configured to hold a compressible container of the flowable substance and to force the flowable substance out of the compressible container by applying a compressive force to the compressible container. The tubing allows communication of the flowable substance between the compressible container and the pump.

First claim

What is claimed is:

1 . A sample dispenser comprising:
a dosing unit configured to dispense sampling amounts of a flowable substance, the dosing unit comprising a nozzle and a mechanical pump communicating with the nozzle; a cradle assembly comprising a priming cradle configured to hold a compressible container of the flowable substance and to force the flowable substance out of the compressible container by applying a compressive force to the compressible container; and tubing connecting the dosing unit and the cradle assembly allowing communication of the flowable substance between the compressible container and the pump.

2 . The sample dispenser of claim 1 , wherein the priming cradle comprises a substantially hollow shell having hingedly-connected front and rear portions configured to hold the compressible container therebetween.

3 . The sample dispenser of claim 2 , wherein the front portion is configured to rotate relative to the rear portion between an open position in which the priming cradle receives the compressible container and a closed position in which the priming cradle applies the compressive force to the compressible container.

4 . The sample dispenser of claim 1 , wherein the priming cradle comprises a tapered interior surface that applies the compressive force to the compressible container when the priming cradle is closed around the compressible container.

5 . The sample dispenser of claim 1 , wherein the cradle assembly further comprises a dock having a receiving area and therein a floor from which projects an upwardly-oriented hollow connector configured to attach to an opening in the compressible container.

6 . The sample dispenser of claim 5 , wherein the cradle assembly further comprises an L-shaped joint having a first end attached to the upwardly-oriented hollow connector and a second end attached to the tubing.

7 . The sample dispenser of claim 5 , wherein the dock comprises a perimeter wall projecting upward from the floor and at least partially surrounding the receiving area, the perimeter wall configured to hold the compressible container in an upward orientation within the receiving area.

8 . The sample dispenser of claim 7 , wherein the dock comprises a retaining wall projecting upward from the floor and spaced from the perimeter wall;
wherein a lower edge of the priming cradle is configured to fit within a space between the perimeter wall and the retaining wall when the priming cradle is attached to the dock.

9 . The sample dispenser of claim 7 , wherein the dock comprises one or more retaining clips projecting upward from the floor and spaced from the perimeter wall;
wherein the retaining clips are configured to allow a lower edge of the priming cradle to slide over the retaining clips toward the perimeter wall and to hold the lower edge of the priming cradle between the retaining clips and the perimeter wall.

10 . The sample dispenser of claim 1 , wherein the dosing unit further comprises an L-shaped joint having a first end attached to the mechanical pump and a second end attached to the tubing.

11 . The sample dispenser of claim 1 , wherein the tubing extends substantially horizontally between the dosing unit and the cradle assembly;
the sample dispenser further comprising an elongate tray extending substantially horizontally over the tubing between the dosing unit and the cradle assembly.

12 . The sample dispenser of claim 11 , wherein the elongate tray comprises engagement features configured to releasably attach the elongate tray to at least one of the dosing unit and the cradle assembly.

13 . The sample dispenser of claim 1 , wherein the priming cradle is configured to force the flowable substance through the tubing and into the dosing assembly;
wherein the mechanical pump is configured to draw the flowable substance through the tubing once the flowable substance has reached the dosing assembly.

14 . A sample dispenser comprising:
a dosing unit configured to dispense sampling amounts of a flowable substance, the dosing unit comprising a nozzle and a mechanical pump communicating with the nozzle; and a cradle assembly comprising a priming cradle configured to hold a compressible container of the flowable substance and to force the flowable substance out of the compressible container by applying a compressive force to the compressible container; wherein the dosing unit is connected to the cradle assembly allowing communication of the flowable substance between the compressible container and the pump.

15 . The sample dispenser of claim 14 , wherein the priming cradle comprises a substantially hollow shell having hingedly-connected front and rear portions configured to hold the compressible container therebetween;
wherein the front portion is configured to rotate relative to the rear portion between an open position in which the priming cradle receives the compressible container and a closed position in which the priming cradle applies the compressive force to the compressible container.

16 . The sample dispenser of claim 14 , wherein the priming cradle comprises a tapered interior surface that applies the compressive force to the compressible container when the priming cradle is closed around the compressible container.

17 . The sample dispenser of claim 14 , wherein the cradle assembly further comprises a dock having a receiving area and therein a floor from which projects an upwardly-oriented hollow connector configured to attach to an opening in the compressible container.

18 . A method for dispensing a flowable substance from a sample dispenser, the method comprising:
providing a sample dispenser comprising a cradle assembly, a dosing unit, and tubing connecting the cradle assembly to the dosing unit; attaching a compressible container of the flowable substance to a hollow connector of the cradle assembly; applying a compressive force to the compressible container by closing the cradle assembly around the compressible container, the compressive force causing the flowable substance to flow out of the compressible container, through the tubing, and into the dosing unit; and operating a mechanical pump of the dosing unit to dispense the flowable substance from a nozzle of the dosing unit communicating with the mechanical pump.

19 . The method of claim 18 , wherein applying the compressive force to the compressible container comprises closing a priming cradle of the cradle assembly around the compressible container;
wherein the priming cradle comprises a tapered interior surface that applies the compressive force to the compressible container when the priming cradle is closed around the compressible container.

20 . The method of claim 18 , wherein attaching the compressible container to the hollow connector comprises placing the compressible container in a dock of the cradle assembly;
wherein the dock comprises a receiving area and therein a floor from which the hollow connector projects upward.
