Disclosed is an inverted constant-volume injection mechanism using an actuator which comprises a valve member (5), a movable member (6), a pressing-on operation member (7), and a pressing operation lever (8). On the basis of an operation by a user to bold a container main body and press the pressing-on operation member (7) onto the scalp (13) or a pressing operation by the pressing operation lever (8), first, output valves (5a, 7d) of the actuator art closed and a flow-in valve (4b) of a stem (4) is opened so that the content in the container main body flows into a constant amount chamber (A) defined between the flow-in valve (4b) to the output valves (5a, 7d). On the basis of a releasing operation performed thereafter, the stem (4) returns to a static mode position and the flow-in valve (4b) is closed, so that the content in the constant amount chamber (A) passes through the output valves (5a, 7d) which are opened by the effect of the liquefied gas, and is injected to the external space through a hole (7c) of the pressing-on operation member (7).

Improvements in an aerosol can liquid dispenser to provide a method to dispense a limited amount of fluid from within an aerosol can and to hold the fluid in a reservoir so it can be intermittently used. An operator may only dispense a few drops of liquid and use only a fraction of the dispensed quantity. The collection reservoir is located in a semi protected enclosure to minimize air flow over the fluid thereby reducing evaporation. A secures mechanism allows the dispenser to be quickly and easily mounted and removed from the top of an aerosol can. A removable cap closure to reduce evaporation of any dispensed fluid held in a reservoir. An overflow reservoir collects any excess fluid where it is held in a separate chamber and can be reclaimed.

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.

A metering valve adapted to be mounted on a container for delivering a liquid under pressure contained in the container, of the type comprising a metering head with an elastic membrane, an end-sleeve, a valve body and a piston sliding in the valve body and formed with a blind central bore and a radial throughgoing hole opening into the central bore. The valve body is made of two portions, a lower portion positioned to be located inside the container when the valve is mounted on the container and an upper portion applied on the lower portion positioned to be inside the container, but extending outside the container on a major portion thereof when the valve is so mounted. The upper portion of the valve body is formed with a bore in which slides a piston limited upwardly by a shoulder forming an abutment for the piston. The piston is formed with an outer annular groove in its central portion surrounded by two O-rings. The radial throughgoing hole of the piston opens into the annular groove.

The present device dispenses product from a pressurized container. The device has a metered valve that dispenses a predetermined fixed quantity of product upon actuation. The metered valve can be configured by the customer with a spacer to affect the amount of product continually metered.
摘要:
An 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.
