Abstract
An apparatus is disclosed for operating an aerosol container equipped at one end with a dispenser valve having a valve stem urged outwardly to a normally closed position away from a depressed open position. The apparatus, which actuates the dispenser valve, comprises a housing constructed to receive at least the valved end of the container. A lever is pivotably mounted in the housing and is operatively associated with the valve stem when the housing receives the valved end of the container. The lever is pivoted to depress the valve stem and open the dispenser valve by a drive assembly that includes a drive shaft rotatably mounted in the housing, a motor for rotating the drive shaft, and a flexible band having one end attached to the lever and an opposite end attached to the drive shaft to be wound thereon.
Claims5
An apparatus for operating an aerosol container to dispense the contents thereof, the container having a dispenser valve at one end actuated through a valve stem urged outwardly therefrom to a normally closed position away from a depressed open position, said apparatus comprising:
- A. a housing formed to receive at least the valved end of the container;
- B. lever means pivotally mounted in said housing, operatively associated with the valve stem when the valved end of the container is received in said housing;
- and
- c. means for pivoting said lever means to depress the valve stem including
- 1. a shaft rotatably mounted in said housing;
- 2. drive means for rotating said shaft;
- and
- 3. a flexible member having one end attached to said lever means and a second end attached to said shaft to be wound thereon;
- whereby rotation of said shaft by said drive means winds said flexible member thereon to pivot said lever means and depress the valve stem.
An apparatus for operating an aerosol container to periodically dispense the contents thereof, the container having a dispenser valve at one end actuated through a valve stem urged outwardly therefrom to a normally closed position away from a depressed open position, said apparatus comprising:
- A. a housing formed to receive at least the valved end of the container;
- B. a fixed pivot shaft mounted in said housing;
- C. a lever pivotably mounted in said housing on said pivot shaft, operatively associated with the valve stem at a location spaced from said pivot shaft when the valved end of the container is received in said housing;
- d. means for pivoting said lever to depress the valve stem including
- 1. a drive shaft rotatably mounted in said housing;
- 2. motor means for rotatively driving said drive shaft;
- and
- 3. a flexible band member having one end attached to said lever at a location spaced from said pivot shaft and spaced from the location of lever association with the valve stem, and an opposite end attached to said shaft to be wound thereon;
- and
- E. timer means for periodically actuating said motor means to wind said band member on said drive shaft, pivot said lever about said pivot shaft, and depress the valve stem.
