Abstract: An actuator for dispensing the liquid contents of a container in the form of a spray includes an actuator cap, an axial spray channel with an orifice for spraying the contents of the container, and an axial feed channel for connection a container outlet to the spray channel. A breakup wedge is provided in the feed channel such that it splits the feed channel into two sub channels, each connected via a side inlet opening with an inlet portion of the spray channel. Thus, in use, a flow of content is split into two sub flows by the breakup wedge, which sub flows subsequently collide in the inlet portion of the spray channel causing a turbulent flow of the liquid product in the inlet portion of the spray channel, which turbulent flow is guided by the spray channel towards and out of the dispensing opening.

Abstract: A device for dispensing a liquid product as an atomized spray includes a container, a depressible dispensing head for initiating emission of the spray from the device and for terminating emission of the spray from the device, and a sequential delivery valve attached to the dispensing head. The dispensing device is configured to initiate flow of gas only into the dispensing head first when the dispensing head is depressed from a first axial position to a second axial position.

Abstract: A sequential delivery valve provides sequential delivery of gas propellant and liquid product from a container to a dispensing head for ejecting an atomized spray from the dispensing head. When the dispensing head is depressed, a pusher in the valve passes from a closed position wherein no liquid and no gas is allowed to travel through the valve to a partially open position where only gas is allowed to travel through the valve and eventually to a fully open position wherein both gas and liquid are allowed to travel through the valve into the dispensing head. When the dispensing head is released, the pusher passes from the fully open position back to a partially open position allowing only gas to travel through the valve and eventually to the closed position wherein no gas and no liquid are allowed to travel through the valve into the dispensing head.

Abstract: In the present invention we replace a standard dip tube in a fluid dispenser with a hollow fiber membrane that passes liquid in preference to gas. Under the influence of a pressure differential, any liquid in contact with any portion of the hollow fiber membrane passes through the wall of the membrane and travels internally along the length of the membrane to a dispenser head. The fluid dispenser is thereby capable of operating in substantially any orientation and is effective to dispense substantially its entire contents.

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.

Abstract: The handheld spray receptor provides an apparatus which, when used with a supply of a liquid under pressure, dispenses a liquid material in a pattern that is controlled by an inexpensive and disposable actuator. Such actuators are employed as an industry standard part that would be found on any aerosol spray can, and feature small cylindrical actuators that may be easily interchanged, so as to provide varied spray patterns. A purging model provides for a quick and convenient method of purging liquid from the actuator, so as to prevent hardening of liquid material exposed to the atmosphere, and a subsequent clogging of the receptor. When used with a supply of liquid under pressure and access to a propellant, the handheld spray receptor significantly reduces the amount of hazardous waste, in the form of partially consumed aerosol cans, that would otherwise enter landfills or hazardous waste recycling facilities.

Abstract: A valve assembly can automatically dispense aerosol content from an aerosol container at predetermined intervals without the use of electric power. A diaphragm at least partially defines an accumulation chamber that receives gas propellant from a portion of the can during an accumulation phase. Once the internal pressure of the accumulation chamber reaches a predetermined threshold, the diaphragm moves, carrying with it a seal so as to unseal an outlet channel, and thereby initiate a spray burst of the main active chemical. The diaphragm assumes its original position when the pressure within the accumulation chamber falls below a threshold pressure.
