Claims
- 1. An aerosol actuator defined by a housing having an inner actuator chamber, an inner actuator chamber outlet by which a composition to be dispensed may exit the inner actuator chamber, the inner actuator chamber outlet having an outlet axis, and a stem piece channel, by which the composition to be dispensed may enter the inner actuator chamber, the stem piece channel having a stem axis, both the inner actuator chamber outlet and the stem piece channel being substantially circular in cross section, the outlet axis being located substantially perpendicularly to the stem axis, an intersection of the stem axis with the outlet axis defining an actuator point, the inner actuator chamber not extending more than a radius of the stem piece channel along the outlet axis in a direction opposite the inner actuator chamber outlet from the actuator point, the inner actuator chamber not extending more than 5 times a radius of the inner actuator chamber outlet along the stem axis in a direction opposite the stem piece channel from the actuator point, an inner surface of the inner actuator chamber being mathematically continuous with an inner surface of the inner actuator chamber outlet; and wherein the inner actuator chamber is dome shaped in a direction extending along the stem piece axis opposite to the stem piece channel.
- 2. An aerosol actuator according to claim 1, wherein the inner surface of the inner actuator chamber is mathematically continuous with an inner surface of the stem piece channel.
- 3. An aerosol actuator according to claim 1 wherein the inner actuator chamber extends from 2.5 to not more than 5 times the radius of the inner actuator chamber outlet along the stem axis in a direction opposite the stem piece channel from the actuator point.
- 4. An aerosol actuator according to claim 2 wherein the dome shaped inner actuator chamber extends in the direction of the outlet axis in the direction of the inner actuator chamber outlet by at least the radius of the stem piece channel.
- 5. An aerosol actuator according to claim 4 wherein the dome shaped inner actuator chamber has an axis substantially parallel to the stem piece axis.
