Abstract

A dispensing system includes a conduit having a volumetric capacity between an internal discharge orifice for receipt of a flow of pressurized fluid from a valving assembly and an external discharge orifice. The dispensing system further includes a volume of pressurized fluid and a sensor. The fluid has a volumetric flow rate of about 0.05 ml/ms to about 15 ml/ms when released into the conduit from the internal discharge orifice. The sensor detects a sound at the external discharge orifice.

Claims

1. A dispensing system, comprising:

a conduit including a valve stem of an aerosol container and a volumetric capacity between an internal discharge orifice for receipt of a flow of pressurized fluid from the valve stem and an external discharge orifice;

a volume of pressurized fluid; and

a sensor,

wherein the fluid has a volumetric flow rate of about 0.05 ml/ms to about 15 ml/ms when released into the volumetric capacity from the internal discharge orifice,

wherein the sensor detects a sound at the external discharge orifice,

wherein the sensor detects a level of the sound that corresponds to different flow rates, and

wherein a ratio of a threshold level of sound to the detected level of sound during an actuation state is less than one at a first stage and substantially unity at a second stage.

2. The dispensing system of claim 1, wherein the first stage corresponds to a positive level of product in a container and the second stage corresponds to an empty or low amount of product in the container.

3. The dispensing system of claim 2, wherein a user perceivable cue is provided to indicate the second stage.

4. A dispensing system comprising:

a conduit including a valve stem of an aerosol container and a volumetric capacity between an internal discharge orifice for receipt of a flow of pressurized fluid from the valve stem and an external discharge orifice;

a volume of pressurized fluid; and

a sensor,

wherein the fluid has a volumetric flow rate of about 0.05 ml/ms to about 15 ml/ms when released into the volumetric capacity from the internal discharge orifice,

wherein the sensor detects a sound at the external discharge orifice,

wherein the sensor detects a frequency characteristic of the sound that is generated by at least one of a shape of the conduit and a product formulation, and

wherein a controller initiates or prohibits at least one of an initial or subsequent actuation of the dispensing system based on the detected frequency characteristic.

5. The dispensing system of claim 4, wherein the controller implements an operational parameter associated with the detected frequency characteristic during actuation of the dispensing system.

6. The dispensing system of claim 5, wherein the controller implements an operation associated with the detected frequency characteristic.

7. A dispensing system, comprising:

a conduit including a valve stem of an aerosol container and a volumetric capacity between an internal discharge orifice for receipt of a flow of pressurized fluid from the valve stem and an external discharge orifice;

a volume of pressurized fluid; and

a sensor,

wherein the fluid has a volumetric flow rate of about 0.05 ml/ms to about 15 ml/ms when released into the volumetric capacity from the internal discharge orifice,

wherein the sensor detects a sound at the external discharge orifice, and

wherein a ratio of the level of volumetric flow rate during an actuation state to a threshold level of volumetric flow rate is less than one at a first status and substantially unity at a second status.

8. A dispensing system, comprising:

a sensor for detecting a sound emitted from a reservoir of fluid having a conduit; and

a controller having a plurality of preprogrammed operational parameters associated with a plurality of preprogrammed frequency characteristics, wherein the controller compares a frequency characteristic of the sound to the plurality of preprogrammed frequency characteristics, and wherein the sensor further detects a sound from an environment to activate the dispensing system.

9. The dispensing system of claim 8, wherein the controller determines a match between the detected frequency characteristic and at least one of the plurality of preprogrammed frequency characteristics.

10. The dispensing system of claim 9, wherein the controller implements the preprogrammed operation parameter associated with the matched preprogrammed frequency characteristic.
