  • Patent number: 6971557
    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.

  • Publication number: 20040149781
    Abstract: A pressure resistant plastic bottle for containing and dispensing an aerosol composition. The plastic bottle is comprised of a hollow elongate body having a longitudinal axis and an outer wall. The outer wall defines a central portion, a top portion and an opposite bottom portion with the central portion having a circular cross-sectional configuration taken through a plane perpendicular to the longitudinal axis and having an inwardly concave configuration extending along its longitudinal direction. The bottom portion of the elongate body is integral with the central portion and defines an outwardly projecting convexly shaped configuration. The top portion of the bottle is integral with the central portion and has an outwardly convex configuration extending along its longitudinal direction and defines a neck having an opening for receiving and dispensing the aerosol composition. A closure covers the opening and is sealingly attached to the neck to contain the aerosol within the plastic bottle.

  • Patent number: 6415957
    Abstract: Apparatus for dispensing a heated gel includes a housing having a recess therein, a coupling assembly disposed in the housing and adapted to retain a pressurized gel container in the recess and a heater assembly disposed in the housing. The heater assembly includes a heater selectively operable to develop heat and a heat exchanger in heat transfer relationship with the heater and having a chamber for receiving a quantity of gel. The heater assembly further includes a first valve in fluid communication with a first portion of the chamber and operable to expose the chamber to pressurized gel and a second valve in fluid communication with a second portion of the chamber and operable to allow dispensing of gel without substantial foaming.
