摘要:
A container for storing and dispensing a liquid product includes a pump operated by a reciprocable control member and associated with a pneumatic servo system. The actuation is achieved by supply of gas pressure, for example, from a reservoir of gas at a pressure of the order of 5 bars, and this is used to actuate the control member of the pump, for example a stepped piston incorporating a pressure multiplying effect. Much higher operating forces on the reciprocable control member can be achieved with this system than were possible by purely manual operation of the valve control member.

A combination aerosol container carrier and deceleration chamber carries an aerosol container interiorly of the deceleration chamber and by pulling out and, pivoting the aerosol container in its case, is changed to a dispensing configuration in such a manner that essential parts are not apt to be dropped and incorrect assembly is avoided even when the user is under stress or adverse environmental conditions. The dispenser provides for unitary doses of inhalable medicament, with uniform doses and very convenient administration.

A dip tube whose tip portion can reach the nooks at the bottom of an aerosol container, so that the aerosol content therein can be assuredly sprayed with substantially no aerosol content being left unused. A weight fixed around the dip tube is arranged so that it does not hit the inner surface of the aerosol container. The dip tube is provided in an aerosol container and an end portion thereof is connected to a valve mechanism. The opposite end of the dip tube is left free. The dip tube conveys the aerosol content from the container to the valve mechanism where it is emitted as an aerosol spray. The dip tube includes a pliable tube main body and a tubular weight fixed on the tube main body adjacent to the free end. An end portion of the tube main body is therefore left exposed by the tubular weight. The length of the exposed end portion is selected so that the end portion is assuredly interposed between the weight and the interior surface of the container.

Device for mixing at least two products (11, 21) each contained in a container (10, 20), one of the containers (10), or first container, having a volume suitable to receive the product (21) contained in the other container (20), or second container, in order to obtain the mixture (41) of the two products (11, 21), the first container (10) comprising, in its upper part, a push-button (15) equipped with a nozzle (16) and the actuation of which allows the mixture (41) to leave the first container (10) via the nozzle (16); the two containers (10, 20) are carried by a common casing (30) into which they are fitted so as to slide between two positions, a position called far-apart position for which the two containers (10, 20) are not in communication, and a position called close-together position for which the two containers (10, 20) are in communication, the casing (30) preventing, in the far-apart position, any action on the push-button (15) of the first container (10) and allowing action on the said push-button (15) in the close-together position, communication means (17, 18, 22) which can be closed off being provided between the two containers (10, 20).
摘要:
A trigger (18), containing one component (28) of a two component gas generating system and having a headspace (37), is closed by a pressure rupturable membrane (36) and located in an expandable pouch (10), in a reservoir of the other component (19) of the gas generating system, with the membrane (36) facing down. The pouch (10) is inserted into a dispensing container (44) for flowable product, and the container is sealed. Thereafter, the trigger (18) is activated by externally pressurizing the container by back flow of fluid through a dispensing valve (46), either by adding a gas or by adding flowable product, causing the membrane (36) to rupture and the trigger (18) to discharge its contents into the reservoir of the other gas generating chemical (19).
摘要:
To avoid the use of propellants which are harmful to the environment, a spraying apparatus employs a supply chamber which contains a material to be sprayed and includes a pressure chamber of variable volume. This pressure chamber of variable volume is connected to actuating structure which is provided for increasing the volume of the pressure chamber and thus for sucking material from the supply chamber into the pressure chamber. Since the material within the pressure chamber is kept under pressure by pressurizing structure, a nonreturn valve is disposed in the suction conduit leading to the supply chamber. Material can be sprayed with the aid of the spraying apparatus without any harmful effects on the environment, the use of conventional spraying heads being here possible.
摘要:
An aeorsol dispensing apparatus for dispensing a liquid under pressure as an aerosol without the use of a pre-dosed propellant, comprising a container for storing the liquid to be sprayed, spray mechanism, and a mechanism for manually introducing atmospheric air into the apparatus to generate a positive pressure therein, the spray mechanism having a nozzle by which the fluid may be dispensed and a feeder pipe to supply the nozzle with fluid to be sprayed, characterized in that the apparatus additionally comprises an intermediate spacer collar which supports the spray mechanism, and to which the container may be attached.

The invention concerns a process for the production and packaging of a bag-type dispenser comprising a casing surmounted by a dome, a sealed flexible bag fixed in said casing and dispensing means sealingly connected to said dome and to said bag characterized in that, prior to any other assembly and packaging operation, a dome of plastics material is produced by moulding, the dome comprising an internal tubular portion permitting sealing fixing thereon on to the upper end of a skirt forming the blank for the bag, and then said fixing is produced, thus providing a preassembled component, dome+skirt, the dome further comprising portions for fixing thereof respectively on to the upper end of the casing and to the dispensing means. The invention also concerns the resulting sub-assemblies and bag-type dispensers. The invention is used in the pharmaceutical, cosmetological, hygiene and foodstuff fields.
摘要:
A valve to be installed on containers for fluid materials is formed by two coaxial chambers (3) and (4) one of which is internal (3), contains the fluid material and is equipped with a movable piston (10) and a discharging valve (7) including at least one "bypass" hole (8) which connects the two coaxial chambers (3) and (4) in the area between the maximum level of the fluid (18) and the discharging valve (7). An elastic sheath or rubber ring (5) is provided to close and wrap tightly the hole (or holes) (8).
