摘要:
A high flow valve for use in conjunction with a compressed gas, an aerosol or in bag-on-valve applications, and particularly to a valve having a housing that is supported by a mounting cup for a product container or can, and communicates with a product or product containment bag inside the can. A radial opening or orifice of the valve is positioned closer to a lower seal of the valve stem, rather than an upper seal or mounting cup gasket, to facilitate an increased flow rate for dispensing the product from the container and the valve.

A apparatus for delivering a predetermined quantity of content from a pressurized container includes a dispensing assembly which sits on the container and connects with an upper portion of a valve stem of the valve assembly, wherein the dispensing assembly includes a) an actuator cap having a discharge passage, which is open or obstructed and wherein the actuator cap acts as a metering chamber in combination with b) an adaptor which fits inside the cap and also snuggly engages the valve stem. The cap fits snuggly over the adjuster to define a metering chamber which depending on its position can close off the metered chamber or open it to the dispensing conduit\nozzle. When the cap is depressed it pushes down on the adjuster which depresses the valve. The chamber fills, but nothing is released until the upstroke.

A metering valve has an elongate axially moveable stem having a discharge passage. A flexible bag for containing a formulation to be discharged surrounds the lower end of the metering valve. The valve is fillable through a fill passage having one end opening to the ambient and the other end opening into the bag. A one-way valve in the fill passage prevents liquid in the bag from escaping through the fill passage but allows the bag to be filled after the lower end of the valve and the bag are inserted into a container and the container pressurized with a propellant.
摘要:
An aerosol device for dispensing texture material for matching existing acoustical ceiling texture. The device comprises a container, a valve assembly, a dispensing nozzle, a hardenable material, and pressurized inert gas as a propelling mechanism. The hardenable material and pressurized inert gas are placed into the container. When the valve assembly is opened, the inert gas forces the hardenable material out of the container through the dispensing nozzle. The dispensing nozzle diverts at least a portion of the hardenable material exiting the container to develop a spray suitable for the application of the hardenable material onto the ceiling surface being textured. The hardenable material preferably comprises at least water, filler, binder, and polystyrene particles. The inert gas is preferably nitrogen.
摘要:
An apparatus for dispensing a metered dose of a product, and a method for using the apparatus. The dispensing device has a charging configuration in which an outlet (112; 212) is closed and a metering chamber (120; 220) is configured to expand to its expanded configuration while receiving product through an inlet (111; 211). It also has a discharging configuration in which the outlet (112; 212) is open and the metering chamber (120; 220) is configured to contract to its contracted configuration while expelling the received product through the outlet (112; 212), thereby dispensing a metered dose of product. The dispensing device further comprises a latch mechanism (140; 240), configured to retain the dispensing device in the charging configuration until the metering chamber (120; 220) attains its expanded configuration. The method comprises actuating an actuator (130; 230) of the dispensing device, to fill the metering chamber, and releasing the actuator to dispense the metered dose of product
