Abstract

A volatile material dispenser includes a housing adapted to receive a container, wherein the container includes a tilt-activated valve stem with a discharge end. The discharge end of the valve stem is adapted to be in fluid communication with a discharge orifice of the housing. A drive unit is disposed within the housing, wherein the drive unit includes a bi-metallic actuator, a piezo-linear motor, an electro-responsive wire, or a solenoid, which is adapted to impart transverse motion to a body of the container.

Claims

1. A volatile material dispenser, comprising:

a housing adapted to retain a container in a suspended operable position by a portion of the container not including a valve stem, wherein the container includes a tilt-activated valve stem with a discharge end, and wherein the discharge end of the valve stem is adapted to be in fluid communication with a discharge orifice of the housing; and

a drive unit disposed within the housing, wherein the drive unit includes a bi-metallic actuator, a piezo-linear motor, an electro-responsive wire, or a solenoid, which imparts transverse motion to a body of the container.

2. The volatile material dispenser of claim 1, further comprising a container that is received in the housing.

3. The volatile material dispenser of claim 1, further comprising a container that is removably retained inside the housing at an upper portion of the container.

4. The volatile material dispenser of claim 1, wherein a longitudinal axis of the drive unit is disposed parallel to a longitudinal axis of a container in a pre-actuation position.

5. The volatile material dispenser of claim 1, wherein the transverse motion is imparted in response to the receipt of an electronic signal.

6. The volatile material dispenser of claim 5, wherein the electronic signal is generated by a sensor.

7. The volatile material dispenser of claim 5, wherein the electronic signal is generated by a timing circuit.

8. The volatile material dispenser of claim 5, wherein the electronic signal is generated by the depression of a manual pushbutton.

9. A volatile material dispenser, comprising:

a housing adapted to receive a container having a tilt-activated valve stem, wherein the housing includes a discharge orifice and a resilient retaining structure adapted to retain the container in an operable position by a portion of the container not including the valve stem;

a dispensing member adapted to be disposed on a portion of the valve stem, wherein the dispensing member substantially immovably secures the valve stem and places same in fluid communication with the discharge orifice; and

a drive unit disposed within the housing, wherein the drive unit includes a bi-metallic actuator, a piezo-linear motor, an electro-responsive wire, or a solenoid, which imparts a transverse motion to a body of the container; and

said retaining structure is adapted to bend resiliently when said motion is imparted to the body of the container.

10. The volatile material dispenser of claim 9, further comprising a container that is received in the housing.

11. The volatile material dispenser of claim 9, wherein the drive unit includes an armature adapted to move along a path substantially parallel to a longitudinal axis of the housing.

12. The volatile material dispenser of claim 9, wherein the transverse motion is imparted in response to the receipt of an electronic signal.

13. The volatile material dispenser of claim 12, wherein the electronic signal is generated by at least one of a sensor, a timing circuit, and the actuation of a manual pushbutton.

14. The volatile material dispenser of claim 9, further comprising a control circuit for automatically generating an activation signal to send to the drive unit.

15. A volatile material dispenser, comprising;

a housing adapted to receive a container having a tilt-activated valve stem, wherein the housing includes a discharge orifice and a resilient retaining structure, and wherein the discharge orifice is adapted to receive the valve stem and the resilient retaining structure is adapted to retain an upper portion of the container not including the valve stem; and

an electric drive unit disposed within the housing, wherein the drive unit engages a lower portion of the container to actuate the valve stem; and

said retaining structure is adapted to bend resiliently when the drive unit engages a lower portion of the container.

16. The volatile material dispenser of claim 15, further comprising a container that is received in the housing.

17. The volatile material dispenser of claim 15, further comprising a dispensing member that secures the valve stem in a position substantially parallel with a longitudinal axis of the housing and aligns the valve stem with the discharge orifice.

18. The volatile material dispenser of claim 15, wherein the drive unit engages the body of the container proximate a bottom of the container.

19. The volatile material dispenser of claim 15, further comprising a selectable switch for setting an automatic actuation of the drive unit.

20. The volatile material dispenser of claim 15, further comprising a pushbutton for manually actuating the drive unit.
