  • the method of packaging and dispensing according to the invention is essentially characterized by the fact that it utilizes a container comprising a dispensing valve having two fluid passageways and positioned at the top of a closed outer jacket.
  • One of the passageways in the valve leads to the outlet of an inner container having rigid lateral walls, the bottom of which is formed by part of a first movable piston member.
  • One of the fluids to be dispensed is introduced into this inner container.
  • a second movable piston is positioned at the bottom of the outer jacket and slidable therein. This second piston is mechanically connected to the first piston.
  • the second fluid, which is to be dispensed simultaneously with the first fluid is introduced into the outer jacket above the piston at the bottom of said jacket. Pressure is exerted against at least one of these pistons to an extent sufficient to displace it in the direction of the dispensing valve and the mixture is dispensed through said valve in response to the pressure applied to the fluid by the two pistons.
  • the container according to the invention comprises a cylindrical outer jacket carrying at its upper end a dispensing valve having two fluid passageways therein. At its lower end is a base provided with means permitting the introduction of a pressurizing gas into the jacket.
  • the device also comprises a cylindrical tube the outlet of which is attached to one of the passageways in said valve. The base of this tube is open.
  • the device comprises a double piston having a central portion which is slidable inside the tube and an annular portion which is slidable inside the outer jacket and outside the tube.
  • This type of device may advantageously comprise a valve having an axial passageway and a lateral or peripheral passageway.
  • the height of the two pistons is preferably the same, and is substantially equal to the height of the tube.
  • the two piston bodies are fastened together by a base plate.
  • a chamber containing a pressurizing gas may be provided between the base plate and the bottom of the outer jacket, which bottom is provided with a pin adapted to perforate the wall of the chamber.
  • the two piston members are connected together near their bottoms by blades extending across the annular space which separates them.
  • the height of the two piston bodies is preferably the same, but is not the same as that of the tube.
  • At least one of the two piston members may advantageously carry, in the annular space which receives the lower part of the outer wall of the tube, annular sealing members adapted to maintain a fluidtight seal between the upper and lower faces of the piston.
  • the rigid lateral wall of the tube is so thin that it can be cut by the blades connecting the two parts of the piston together when the pressure exerted by conventional pressurizing gases is applied to the lower surface of the two piston members.
  • Another embodiment of the invention comprises an outer jacket equipped at its upper end with a dispensing valve having two fluid passageways and, at its lower end with a base which carries means permitting the introduction of a pressurizing gas into the jacket.
  • This embodiment also comprises a tube having an outlet connected to one of the passageways in the valve and a piston positioned between the lower end of the tube and the base of the outer jacket, which piston is slidable in sealing contact with the outer jacket and comprises a central portion having a seat which constitutes the bottom of the tube.
  • This second type of device may advantageously comprise a valve having an axial passageway and a lateral or peripheral passageway.
  • the tube may be cylindrical and bottomless and fastened to the axial passageway in the dispensing valve.
  • This tube may be made of a thin aluminum sheet material which may be accordion pleated by the piston.
  • the tube may be made of a sheet of plastic material which is already accordion pleated.
  • a chamber holding a liquefied pressurizing gas is positioned between the lower surface of the piston and the base of the outer jacket.
  • the container is equipped with a pin adapted to perforate the wall of the chamber and which may be actuated from outside the jacket by the user.
  • An overall bending of the tube, which would result in the isolation of part of the product contained therein, may be avoided by providing, inside the outer jacket, in the annular space between the jacket and tube, at least one supporting ring made, for example, of a synthetic resin foam.
  • This supporting ring may advantageously slide inside the outer jacket.
  • the pressurizing gas for collapsing the tube inside the outer jacket is initially included in a chamber at the lower end of the outer jacket. It is obvious that any suitable known means for providing this pressurizing gas may be used.
  • the pressurizing gas may not be initially enclosed inside the outer jacket, but may be introduced from an independent cartridge through a valve placed in the bottom of the outer jacket.
  • the pressurizing gas may also be contained in a cartridge mounted on the lower surface of the piston or pistons in the container according to the invention.
  • the base of the outer jacket will then be equipped with a pin long enough to permit its point to perforate the wall of the cartridge holding the pressurizing gas when the user desires to open the container.
  • Suitable pressurizing gases are butane, trichlorofloromethane, dichlorodifluoromethane, and dichlorotetrafluoroethane. It will be appreciated that one of the essential advantages of containers and of the method of storage according to the invention is to provide simple means making it possible to store two fluids which are to be dispensed separately, and to dispense these two fluids simultaneously in proportions which depend on the diameters of the passages in the valve, which proportions remain constant if the precaution has been taken to completely fill the tube and outer jacket with fluid above their respective pistons.
  • the device also insures the progressive dispensing of the entire volume of fluids stored in the container, which progressive dispensing is rendered possible by the fact that the simultaneous distribution of the two fluids is carried out while the fluids still within the container are still separated from each other.
  • This last advantage is particularly important since it makes it possible to package together two fluids which must react with each other when said fluids are dispensed even when the distribution thereof must be carried out at spaced successive intervals of time.

  • the jacket 1 carries at its upper end a valve 2 of a conventional type provided with an axial passageway and a lateral passageway.
  • Reference numeral 4 indicates the base of the jacket 1. This base carries a central valve 5 through which a liquefied pressurizing gas 6 contained in an independent cartridge 7 may be injected into the jacket 1.
  • the axial passageway in the valve 2 is connected to neck 3 of a container 8.

  • a slidable piston 10 Inside the tube 8 is a slidable piston 10 which is in sealing contact with the tube.
  • the pistons 9 and 10 are separated by an annular space 11 and connected at their lower ends by a base plate 12.
  • Annular seals 13 are provided on opposite sides of the wall of the tube 8 in the annular space 11.
  • the tube 8 is completely filled with a liquid product 14.
  • the jacket 1 is completely filled above the piston 9 with a liquid product 15.
  • the liquids 14 and 15 are thus placed under pressure inside the jacket by the pistons 9 and 10.
  • the push button controlling the valve 2 When the user then presses the push button controlling the valve 2, the passageways in the valve connected to the products 14 and 15 are opened and the two products are simultaneously dispensed while the pistons 9 and 10, connected by the base plate 12, move upwardly in the direction of the valve 2.
  • the user may stop the distribution at any time but the products 14 and 15 nevertheless remain separate inside the container according to the invention.
  • FIG. 2 illustrates the second embodiment of the container according to the invention
  • this embodiment likewise has an outer jacket 1 and a dispensing valve 2 at the top of this jacket.
  • the valve 2 has the same characteristics as the valve described in the case of the first embodiment.
  • the outer jacket 1 has a base 4 surmounted by an inner wall 16 fixed to the base and the envelope by crimping.
  • the wall 16 and the base 4 define therebetween a chamber holding a pressurizing gas 6.
  • the base 4 is provided with a pin 17 which is movable from outside the container, the end of which pin is adapted to perforate the wall 16.
  • the axial passageway in the valve 2 is connected to the neck 3 of a container 8 consisting of a tube similar to the one described in connection with the first embodiment of the invention.

  • the diameter of the tube is 25 mm.
  • the tube is about 150 mm long.
  • the cylindrical part of the jacket 1 is about 180 mm long.
  • annular piston 19 which is adapted to slide in sealing contact with the inside of the outer jacket 1.
  • a piston which is slidable in sealing contact with the inner surface of said tube.
  • the pistons 19 and 20 are connected at their lower ends, that is to say the ends nearest the wall 16, by blades 21 extending across the annular space 22 which separates the pistons 19 and 20.
  • the pistons 19 and 20 carry two annular sealing members 23 and 24 on opposite sides of each other inside the annular space 22, which sealing members grip the wall of the bottomless tube 8 therebetween.
  • the tube 8 is completely filled with a liquid 14 and above the piston 19 the outer jacket 1 is completely filled with a liquid 15.
  • the advantages of this embodiment are the same as those in the embodiment of FIG. 1.
