1. A pressurized pack for dispensing viscous material, semi-solid material, and the like comprising a body for containing a product and a propellant;
- an outlet valve member slidably movable in the body between closed and open positions; and
an actuator having one end fixed with respect to the body, another end forming a handle, and an intermediate portion engaged with the valve member;
the actuator engaging with the valve member via a lock member which is axially movable on the valve member between locked and unlocked positions which respectively prevent and permit movement of the valve member in the body;
the actuator being generally L-shaped with the handle lying adjacent a side wall of the body when the lock member is in said locked position but being angled to said side wall when the lock member is in said unlocked position, the lock member being positionable selectively at any position between said locked and unlocked positions to set the maximum opening of the valve member and thus to select the flow rate of the product, the valve member and the lock member being formed with cooperating screw threads, and a stop provided to limit the maximum travel of the lock member and thus the maximum valve opening travel, said stop comprising one or more shoulders on the lock member cooperating with a tab upstanding from a clip positioned under the lock member.

The valve of an aerosol can is actuated by a lever having a handle portion and an intermediate portion bearing on a lock member. The lever is pivotably mounted in a clip. The lock member is in screw-threaded engagement with the valve for movement the realong between closed and open positions. The lock member can be placed in any intermediate position to set a desired flow rate through the valve when the lever is depressed by the user.
