Abstract

An aerosol foam dip tube dispenser with an axis of symmetry with a pressurizable outer container for storing a propellant and a composition under pressure and an actuator. The aerosol dispenser is ergonomic and promotes upright dispensing in order to avoid degassing.

First claim

What is claimed is:

1. An aerosol dispenser with an axis of symmetry comprising:
a. a pressurizable outer container for storing a propellant and a composition under pressure;
b. an actuator having an outer surface where the actuator is attached to a top of the outer container comprising:
i. a valve being movable to an open position to release a mixture of the aerosol and the composition;
ii. a trigger located above the valve for actuating the valve;
iii. a longitudinally extending nozzle having a top surface, a bottom surface, a nozzle surface comprising one or more shaping orifices with a nozzle direction from less than or equal to 85° from the axis of symmetry of the dispenser;
wherein said orifices are in fluid communication with the valve;
wherein the bottom surface and the outer surface of the actuator create an overhang adapted for receiving the at least a portion of a little finger on a user's receiving hand;
wherein the overhang is shaped to accommodate a semi-cylinder with a radius from about 10 mm to about 30 mm.

2. The aerosol dispenser of claim 1 wherein the actuator body has substantially no tilt during actuation.

3. The aerosol dispenser of claim 1 wherein the nozzle remains in fixed position relative to the to the actuator during actuation of the trigger.

4. The aerosol dispenser of claim 1 wherein the nozzle surface is substantially flat and comprises a surface area from about 100 mm 2 to 1250 mm 2 .

5. The aerosol dispenser of claim 1 wherein the nozzle surface is substantially flat and comprises a surface area from about 300 mm 2 to 500 mm 2 .

6. The aerosol dispenser of claim 1 wherein the nozzle direction is from about 55° to 85°.

7. The aerosol dispenser of claim 1 wherein the actuator further comprises a shroud attached to the top of the outer container and rigidly attached to an actuator body.

8. The aerosol dispenser of claim 7 wherein the shroud forms a twist lock mechanism.

9. The aerosol dispenser of claim 1 wherein the outer container is contoured.

10. The aerosol dispenser of claim 1 wherein the outer container is injection stretch blow molded.

11. The aerosol dispenser of claim 1 wherein the outer container is pressurized to an internal gage pressure of 100-1150 kPa.

12. The aerosol dispenser of claim 1 wherein the outer container is transparent or substantially transparent.

13. An aerosol dispenser with an axis of symmetry comprising:
a. a pressurizable outer container for storing a propellant and a composition under pressure;
b. an actuator having an outer surface where the actuator is attached to a top of the outer container comprising:
i. a valve being movable to an open position to release a mixture of the aerosol and the composition;
ii. a trigger located above the valve for actuating the valve where the trigger has a direction of actuation from about −10° to about 60° from the axis of symmetry of the dispenser at the beginning of a stroke;
iii. a longitudinally extending nozzle having a top surface, a bottom surface, a nozzle surface comprising one or more shaping orifices, wherein said orifices are in fluid communication with the valve;
wherein the bottom surface and the outer surface of the actuator create an overhang adapted for receiving the at least a portion of a little finger on a user's receiving hand;
wherein the overhang is shaped to accommodate a semi-cylinder with a radius from about 10 mm to about 30 mm;

c. a dip tube where an end of the dip tube is connected to the valve.

14. The aerosol dispenser of claim 13 wherein the actuator body has substantially no tilt during actuation.

15. A method of dispensing a foam from an aerosol container comprising:
providing the aerosol foam dispenser of claim 13 ;
b. actuating the trigger;
c. dispensing a foam composition;
wherein during actuation, the aerosol dispenser comprises a 98% ile tilt angle of about 0° to about 90° relative to an axis perpendicular to the ground.

16. The method of claim 15 wherein during actuation wherein during actuation, the aerosol dispenser comprises a 98% ile tilt angle of about 0° to about 76° relative to an axis perpendicular to the ground.

17. The method of claim 16 wherein during actuation wherein during actuation, the aerosol dispenser comprises a 98% ile tilt angle of about 0° to about 67.5° relative to an axis perpendicular to the ground.

18. The method of claim 15 wherein before actuating the outside of the receiving hand or the side of the little finger is brought adjacent to the overhang.

19. The method of claim 15 wherein the peak force to actuate to from about 5N to about 35 N.

20. The method of claim 15 wherein the peak force to actuate to from about 5N to about 20 N.
