  • Patent number: 10077150
    Abstract: A pressurized dispenser includes a base and a peripheral wall having an open end sealed by a dispensing element comprising a dip-tube, a fluid reservoir in contact with the dip-tube for reducing the compressed gas lost from the pressurized dispenser, a compressed gas and a dispensing liquid. In embodiments, a majority of the fluid reservoir may be located outside of the dip-tube, and the fluid reservoir may include a porous material, arranged in use to hold a volume of the dispensing liquid. Such porous material may be configured so that, in use, at least a portion of any compressed gas in the reservoir can be displaced by the liquid, ejecting such portion of the compressed gas into the dispenser. In embodiments, the dispensing element may be configured to dispense dispensing liquid continuously for at least 0.5 seconds, upon actuation of the dispensing element.

  • Patent number: 7926741
    Abstract: An aerosol dispenser has a canister to contain a liquid product to be dispensed together with a propellant present at least partly as a gas and valve to control the release of the liquid product from the canister. The dispenser also has a vapor phase tap for introducing a portion of the gaseous propellant into the liquid product as it is dispensed. The dispenser has a flow control device for varying the rate at which the propellant has is introduced into the liquid product through the vapor phase tape in dependence on the pressure of the contents of the canister. The flow control device can be used to reduce the amount of propellant gas bled into the liquid product, particularly when the dispenser is full and the pressure in the canister is high, as a way of conserving the propellant gas.

  • Patent number: 7757970
    Abstract: This invention relates to pump-action nozzle devices and methods of making the same. The dispenser nozzles of the invention comprises a body which defines an internal chamber having an inlet through which fluid may be drawn into said chamber and an outlet through which fluid present in the chamber may be expelled from the nozzle. The inlet comprises an inlet valve and the outlet comprises an outlet valve. Fluid is dispensed from the dispenser nozzles by pulling the trigger handle of a trigger actuator to resiliently deform or displace a portion of the body of the device that defines the chamber, thereby compressing the chamber and actuating the dispensing of fluid. In preferred embodiments, the outlet comprises an outlet passageway that extends from the chamber to an outlet orifice. One or more spray-modifying features are preferably formed within the outlet passageway.

  • Publication number: 20100127018
    Abstract: A manually actuated pump dispenser (210) has a dispenser main body (212, 214) including a first pump chamber (228) for a first fluid. An actuator (216) is mounted to the dispenser main body for movement towards and away from the dispenser main body. A flexible wall member (266) extends between the dispenser main body and the actuator to define a second pump chamber (268) between the dispenser main body and the actuator for a second fluid. The flexible wall member (266) is attached at one end to the actuator or to a part of the dispenser main body and has a distal end (266A) comprising a collar (265) which is mounted to the other of the actuator and a part of the dispenser main body to form a seal therewith. The flexible wall member may be formed integrally with the actuator or the part of the dispenser main body and the collar, for example by using bi-injection techniques. A method of manufacturing the pump dispenser is also disclosed.

  • Publication number: 20100044400
    Abstract: A pressurised dispenser valve (110) has a valve housing (111) with at least one fluid inlet (127, 128) though which a fluid present in an associated dispenser may pass to enter the valve housing. The at least one fluid inlet is formed at least partly by, or in a resiliency deformable portion (124, 125) of the valve housing. The deformable portion (124, 125) is arranged such that, in use when the valve is opened, it deforms from an initial resiliency biased configuration in which the fluid inlet (127, 128) has an initial cross sectional area to a deformed configuration in which the fluid inlet has an altered cross sectional area in response to a pressure differential between the interior of the housing and the exterior of the housing. The change in cross sectional area of the inlet can be made to vary independence on the pressure in the canister and can be used to control the rate of flow of the fluid through the inlet as the pressure in the canister falls during use.

  • Patent number: 7651013
    Abstract: A nozzle arrangement adapted to be fitted to a pressurized vessel and to permit fluid to be dispensed through it under pressure, is presented. The nozzle arrangement includes a body having an inlet, an outlet, an internal fluid flow passageway through which fluid can flow from the inlet to the outlet, and an actuator portion adapted, upon operation, to engage and open an outlet valve of the pressurized vessel. The nozzle arrangement further includes a resiliently deformable wall member that undergoes a resilient deformation from an initial resiliently-biased configuration to a distended configuration in response to the operation of the actuator portion, and to revert to the initial resiliently-biased configuration when the operation of the actuator portion has ceased and cause any fluid remaining in the passageway to be expelled.
