摘要:
A container with pressure control device for maintaining a substantially constant, pre-set pressure in the container, which is arranged for dispensing a fluid. The pressure control device comprises a first chamber for containing a pressure fluid, in particular a pressure gas, a second chamber in which, at least during use, a control pressure prevails, and a third chamber which is formed by or is in communication with, at any rate is at least partly included in an inner space of the container. Between the first chamber and the third chamber a passage opening is provided in which a closing member is included for closing the passage opening during normal use when the pressure in the third chamber is higher than the control pressure. A control means is movable by a displaceable or deformable part of the wall of the second chamber and is arranged for at least partly displacing the closing member when the pressure in the third chamber is lower than the control pressure, such that the pressure fluid can flow under pressure from the first chamber to the third chamber. Prior to use the control means have been brought into a position in which they are at least functionally uncoupled from the closing member, and the pressure control device is arranged for functionally coupling the control means to the closing member through an activation step prior to use.
摘要:
A pressure control device (1) for maintaining a constant predetermined pressure in a container which is arranged for dispensing a fluid contained in the container from the container at said pressure, the pressure control device comprising a first (4) chamber and a second chamber (6), as well as at least one closing member (8) movable relative to the second chamber for releasing and closing a fluid connection between the first chamber and the container depending on the position of the closing member relative to the second chamber. The first chamber is filled with a gas which, in use, has a higher pressure than the pressure in the container. The second chamber is located outside the first chamber.
摘要:
An aerosol product comprising a double-chamber container separated by a movable partition capable of dividing contents therewith, one spatial portion thereof being loaded with contents to be discharged and the other spatial portion being loaded with compressed gas for pressurizing. The compressed gas is a mixed compressed gas of at least two types of mixed gas, at least a part of the partition presents permeability of the compressed gas, and the mixed compressed gas selectively permeates the partition to be dissolved in the contents to be ready for discharge.

Disclosed is a pressure generation system for a container which includes a pressure pouch (100) having a plurality of compartments (110, 114) containing reactive components (130, 132) of an at least two component gas generation system. The compartments (110, 114) are separated by frangible wall portions (186, 188) which fail or tear in response to increasing volume of an adjacent compartment. The frangible wall portions (186, 188) may each comprise a continuous, integral section of frangible material (150). The frangible wall portions (186, 188) may all be formed from a single sheet of frangible material (150) or, they may alternatively be formed from a plurality of individual sheets (382, 384, 386).
摘要:
A novel foam dispenser is described, which comprises a dispensing container, a valve with a downstream foaming chamber and a pressure control device for maintaining a constant pressure in the container, such that uniform and compact foam will be created.
摘要:
A canister for a metered dose inhaler has high and low pressure chambers for a propellant and for an inhalable drug and vaporised propellant. The low pressure chamber has an opening for a metering valve. A pressure regulating valve is between the high and low pressure chambers and provides a flow path from them. A metering valve dispenses a metered dose. The valve includes a metering valve body having a propellant metering chamber with a propellant inlet and a product metering chamber with a product inlet, and a metering valve stem with a dispensing nozzle, a propellant inlet plug and a product inlet plug. The metering valve stem moves to a dispensing position. In the dispensing position, the propellant and product metering chambers are in fluid communication with atmosphere via the dispensing nozzle of the metering valve stem such that a metered dose of product and propellant can be dispensed.
摘要:
A pressure control system provided for maintaining a constant predetermined excess pressure in a fluid dispensing container comprises a high-pressure plastic vessel having an inner chamber, and a pressure control device having a valve and mounted on the open end of the high-pressure vessel, whereas a passageway is provided from the inner chamber to the outside, which is controlled by the valve. A piston with a protruding stem is provided in a guide member, whereas between the guide member and the piston a chamber with a gas with a reference pressure smaller than the high pressure is enclosed, and the high pressure vessel is closed by a closure with a central bore of smaller diameter than the diameter of the stem, and the piston end remote from the protruding stem is pressurized by the fluid in the fluid dispensing container.
