Actuator for a pressurized material dispenser
First Claim
1. An actuator for use with a pressurized material dispenser containing a material to be dispensed and having a valve, the actuator comprising:
- a skirt suitable for being secured to the dispenser; and
a trigger linked to the skirt via a web in a manner permitting relative movement between the trigger and skirt, the trigger comprising;
a flow conduit terminating at one end in a means for mating with the valve in material-transmitting relation and for activating the valve when the trigger is moved toward the dispenser to thereby dispense contents of the dispenser via the flow conduit, the flow conduit terminating at an opposite end from said one end at a hollow flow diverter;
wherein said flow diverter has a side wall and an axial opening facing said conduit at one end of the flow diverter, a wall at an end of diverter opposite said one end of the flow diverter, and at least 4 radially opening slots in the side wall and in communication with the diverter axial opening;
the trigger also comprising a discharge chamber radially outward from said radially opening slots, the chamber being in communication with said slots and having an outer side wall with a plurality of recesses separated by deflection regions, at least one of the deflection regions having a portion that is circumferentially aligned with respect to one of the radially opening slots of the flow diverter; and
wherein the actuator is configured such that when linked to said pressurized material dispenser it is suitable to deliver the material to be dispensed in an axial direction.

Abstract
An actuator orifice and an actuator for enhancing or creating a foam from a pressurized material dispenser. The actuator includes a skirt attached to the dispenser and a trigger movably mounted to the skirt. The trigger includes a flow conduit with a socket for receiving a valve stem. The socket exerts pressure on the stem to release contents of the dispenser. The trigger includes a hollow flow diverter located within the chamber. The flow diverter has a side wall and an end wall extending inwardly from the flow diverter side wall. The flow diverter side wall in turn has slots that provide fluid paths between the flow conduit and a surrounding chamber. The chamber side wall has recesses. Each slot laterally directs contents of the dispenser into at least one of the recesses in the chamber side wall when the valve is activated by the trigger.

10. A pressure container dispenser comprising:
-
a pressure container containing a pressurized material to be dispensed, the pressure container having a valve stem projecting outward from the pressure container; and an actuator positioned on the pressure container, the actuator comprising; a skirt suitable for being secured to the pressure container; and a trigger linked to the skirt via a web in a manner permitting relative movement between the trigger and skirt, the trigger comprising; (i) a flow conduit terminating at one end in a stem socket dimensioned and positioned for receiving the valve stem, the stem socket being suitable to exert pressure against the valve stem when the trigger is moved toward the pressure container to thereby dispense contents of the pressure container, and terminating at an opposite end from said one end in a hollow flow diverter;
wherein said flow diverter has a side wall and an axial opening facing said conduit at one end of the flow diverter, a wall at an end of diverter opposite the one end of the flow diverter, and at least 4 radially opening slots in the side wall and in communication with the diverter axial opening; and(ii) a discharge chamber radially outward of said radially opening slots, the chamber having a side wall with a plurality of recesses separated by deflection regions; and wherein the actuator is suitable to deliver the material to be dispensed in an axial direction. - View Dependent Claims (11)

12. An actuator orifice for use with a pressurized, foamable product comprising:
-
a hollow flow diverter having a side wall and having at one end an axial opening to receive foamable product delivered thereto under pressure, a wall at an end of the diverter opposite the one end of the flow diverter, and at least 4 radially opening slots in the side wall and in communication with the diverter axial opening; and a discharge chamber radially outward of said radially opening slots, the chamber having a side wall with a plurality of recesses separated by deflection regions, at least one of the deflection regions having a portion that is circumferentially aligned with respect to one of the radially opening slots of the flow diverter, the discharge chamber also including an opening from which foamed product can be discharged into the hand of a user; wherein more than one of the plurality of recesses has a curved inner surface. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
