摘要:
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.

A device for dispensing a pressurized material, includes a body defining a pressurizing chamber containing a gas generator, and a tank containing the material to be dispensed, the tank being defined by an end wall having an outlet orifice. The device includes a piston, to move inside the body, separating the pressurizing chamber from the tank, the gas generator to trigger the dispensing of the material to the outside of the body through the outlet orifice by causing the piston to pass from a material-storage, first position to an end-of-material-dispensing, second position in which the piston faces the end wall. The piston, when in the first position, presents a housing that is closed by a fragile portion beside the pressurizing chamber and that is open beside the tank, the housing containing a striker element that is held in the housing and that defines a channel opening out into the tank.

A device for dispensing a pressurized material, includes a body defining a pressurizing chamber containing a gas generator, a tank for containing the material that is to be delivered, and a piston, the gas generator being configured so that when it is triggered it causes the device to pass from a material-storage, first configuration to an end-of-material-dispensing, second configuration. In the first configuration, the piston is held in position in the body by an elastically deformable holder element extending axially, that is secured to the first end wall. The piston is held stationary relative to the first end wall by a holding force from the holder element. When the gas generator is triggered, it exerts a force on the piston that opposes the holding force to enable the piston to move by releasing the first end wall and thus causing the device to pass from the first to second configuration.

A device for packaging and dispensing, under pressure, a product is provided. The device can be particularly advantageous for cosmetic products and includes a container containing the product to be dispensed under pressure, a propellant in the form of a liquefied gas having a gaseous phase and a liquid phase, and at least one retaining member able to trap the liquid phase of the propellant. The retaining member includes at least one portion that is permeable to the gaseous phase of the propellant. A valve is associated with the container and includes a body that includes a first passage able, when the device is in a first position, to cause the product contained in the container to enter the valve body when the valve is actuated, and a second passage able, when the device is in the first position, to cause the propellant contained in gaseous form in the container to enter the valve body when the valve is actuated.

A valve assembly for an aerosol can comprises a valve conduit having an inlet, an outlet, a valve seat in the flow path between the inlet and the outlet, and a resilient mounting of a valve member that permits relative movement of the valve member relative to the valve conduit. The valve member further comprises a valve element that is movable to sealingly engaging the valve seat, and a stem projecting from the valve member through the outlet of the valve conduit. During the movement of the valve member relative to the valve conduit, the movable tapered sealing surface associated with the valve member is configured to engage and concentrically align with a tapered valve seat on the valve conduit to establish an effective seal against the valve seat.

An apparatus for dispensing fine particulate matter from a flexible container includes a housing with a first open end and an opposed closed end. A cover is pivotally attached to an open end for selectively opening and closing thereof. A nozzle is attached to the closed end extending into the housing. The nozzle has a passageway extending therethrough and a first end puncturing a wall of the container and enabling the first member to penetrate the container. A pump member is disposed transversely to the nozzle and includes a passageway having a venturi and a venturi throat disposed adjacent a first end. The second end receives a supply of fluid under pressure. A vent is attached to the cover and has one end puncturing and penetrating the wall of the container. Supply of fluid under pressure forms a pressure differential between opposite ends of the container and enables the fine particulate matter to enter the first passage and then the second passage for mixing with the fluid. At least one perforated partition and a passageway connecting the housing and the nozzle are provided to retain the shape of the flexible container.
