A pressure control device for pressure packaging based on a disc with fluid connection and a collecting basin, with associated closing means. The closing mechanism in the pressure control device is no longer based on a cylinder with a central opening in the separation wall and closing-off of the opening by means of a piston with stem. The proposal is extremely simple, compact and easy to assemble. The use of O-rings is superfluous. A method for manufacturing a pressure control system and a kit of parts for the assembly thereof.

A needle for accessing a container having a closure, such as a cork of a wine bottle. The needle includes one or more lumens which may have a screen to resist passage of materials over a threshold size from a distal end of the lumen to a proximal end. The screen may help allow a cork to reseal after the needle is withdrawn from the cork, help resist blockage of an opening to the lumen (whether with cork or other material) and/or help prevent foreign matter from interfering with operation of one or more portions of the dispenser (such as cork particles preventing valve from opening or closing).

An aerosol canister for dispensing a product and propellant, and a product metering valve for use with the aerosol canister. The canister includes a high pressure chamber for containing a liquefied or compressed gas propellant, a low pressure chamber for containing a gas propellant, and a product reservoir for containing a gas propellant. A pressure regulating valve is interposed between the high pressure chamber and the low pressure chamber, the pressure regulating valve adapted to provide a fluid flow path from the high pressure chamber to the low pressure chamber when the pressure in the low pressure chamber drops below a predetermined pressure. The canister further includes a partition wall interposed between the low pressure chamber and the product reservoir.

A container whose content can be removed easily by a consumer. The container should be inexpensive to produce while being extremely easy to operate by the consumer, should provide a high degree of flexibility with respect to the choice of the propellant gas (pressure and type of gas) and should achieve a long storage life for the contents, even after the container has been tapped. The container comprises a fill chamber (40), a pressure chamber (6) and a pressure valve (10). The fill chamber (40) is formed by a container base (2), a container wall (7) and a container upper face (8), and a first pressure (p.sub.B) prevails in the fill chamber (40). The pressure chamber (6) is formed by the container base (2) and a pressure chamber base (5) and a second pressure (p.sub.D) prevails in the pressure chamber (6). The pressure valve (10) is connected to the container base (2) and the pressure chamber base (5). The pressure valve (10), when open, establishes fluid communication between the fill chamber (40) and the pressure chamber (6), and the pressure valve (10), is when closed, separates the fill chamber (40) and the pressure chamber (6) in a fluid-tight manner from one another.

Provided is an aerosol product which has a simple configuration and enables spraying in the form of a mist at the time of use even when a stock liquid is stored in a high-viscosity state in an aerosol container. An aerosol product (100) has a plurality of partitioned housing spaces and a valve unit (120) provided with an inflow port (122) corresponding to the housing space, wherein at least one among the plurality of housing spaces is a main stock liquid housing section (142) that houses a main stock liquid (M), at least one other of the plurality of housing spaces is a viscosity lowering agent housing section (143) that houses a viscosity lowering agent (S), and the main stock liquid (M) discharged from the inflow port (122) and the viscosity lowering agent (S) discharged from the inflow port (122A) are mixed in an actuator (130).

A two-component pressurized can having a body, a dome, a valve arranged in the dome, an inwardly curved bottom and an opening device which is arranged in the bottom and can be actuated through the bottom from the outside, in which the can body has a peripheral necking to which there is secured a separating disk which divides the can into a lower chamber and an upper chamber, wherein the separating disk has a central opening which is closed by a closure element, and wherein the opening device can be moved against the closure element via the triggering member in order to detach the closure element from the separating disk.

A two-component aerosol can for dispensing sealing and assembly foams based on isocyanates, having an outer pressure container which holds a prepolymer component and a propellant gas, the outer pressure container being in communication with a first valve device and with a first channel; an inner container which holds a curing component and a propellant gas, the inner container being in communication with a second valve device and with a second channel; and a spray head which comprises a device for simultaneously actuating the first and second valve devices; and a spray tube into which the first and second channels jointly open
