Definitions

  • the present invention relates to a container for dispensing a product of liquid, or even gelled consistency, pressurized using a propellant gas, this dispenser comprising a safety device.
  • the dispensing container according to the present invention also called dispenser, can be used in different fields of use and serve for the dispensing of cosmetic or pharmaceutical products, household products, paint, etc., in the form of a liquid jet or fine droplets.
  • the invention relates to a dispenser which can be refilled, as the case may be with spray liquid and propellant gas, comprising a reservoir and a valve for dispensing the liquid contained in the reservoir, this dispenser comprising a discharge system in gas, aimed at avoiding accidental overpressure inside the container.
  • a dispenser of the kind defined above must be equipped with a product reservoir which can be opened in order to introduce a new product refill, after the product initially contained in this reservoir has been used up. .
  • a gas source such as a bottle containing a compressible gas or liquefiable, or else on a compressor producing compressed air.
  • the internal pressure prevailing in the reservoir is difficult to control. This pressure must not exceed a predetermined value, otherwise the tank will burst or explode, and therefore cause injury to the user.
  • an overpressure occurs inside, also risking bursting the tank.
  • Document FR-A-2 684 647 discloses a pressurized, non-refillable dispensing container containing a fluid product to be dispensed and a compressed propellant gas.
  • the container is provided with a gas discharge device constituted by a plug of deformable material pressed into an orifice in the wall of the container; the plug has an area of least resistance due to a recess in the plug. This area of least resistance, allows to establish a final communication between the interior of the container and the atmosphere, when it deforms under the effect of an overpressure.
  • This dispenser of the prior art has drawbacks during an overpressure inside the tank. In fact, this overpressure can cause the plug and therefore all of the propellant to be expelled, and the product can no longer be dispensed. Furthermore, when the dispenser is in a position where the product is in contact with the stopper, the overpressure prevailing in the reservoir can also cause the stopper to leave, and simultaneously the product. This is detrimental, especially if the distributor is, at the time of the overpressure, in a suitcase, the entire contents of the suitcase then risking being soiled by the dropped product.
  • a pressurized liquid distributor comprising a safety device, comprising a spring relief valve, capable of closing automatically, after having allowed excess gas to escape. propellant.
  • This dispenser is not designed to be refillable.
  • the object of the present invention is to remedy the drawbacks mentioned above and, in particular, to provide a dispensing container comprising a safety device, and more particularly a gas discharge device intended to avoid internal overpressures.
  • This dispensing container is, in particular, refillable with propellant and product.
  • This product is, in particular, a hair spray or an alcoholic body lotion.
  • the container of the invention when refillable, has the advantage that only part of its constituent parts must be discarded after the product has been used up, the other part of its parts being able to be reused with a new refill. This solution is particularly economical.
  • the refillable dispensing container according to the invention can be manufactured at a lower cost price than those of the prior art.
  • the present invention therefore relates to a dispensing container for dispensing a product comprising: a closed tank; a cylindrical neck; a dispensing head mounted on the neck and a safety device to prevent accidental overpressure inside the container.
  • the safety device comprises annular elastic retaining means surrounding the neck of the reservoir, capable of tightening the dispensing head, in a sealed manner on the neck of the reservoir when the internal pressure of the reservoir is below a predetermined value and to separate the dispensing head from the neck, when the internal pressure exceeds this predetermined value so as to create a communication between the interior of the container and the external atmosphere.
  • this safety device returns to the initial sealed position, when the internal pressure of the container drops below the predetermined value.
  • the dispensing head is advantageously equipped with a dispensing valve having a control rod connected to a push button provided with a dispensing nozzle.
  • This valve can be connected, on the opposite side to the control rod, to a deformable pocket, containing the product to be dispensed or to a dip tube.
  • a deformable pocket When a deformable pocket is used, the product is subjected to the pressure of the propellant gas, via this pocket.
  • the dispensing head provided with the bag and the valve, can constitute an interchangeable refill.
  • the dispensing nozzle is a simple dispensing orifice or a spray nozzle.
  • the dispensing container of the invention is in the form of a sprayer producing a cloud of fine droplets or else a threadlike jet.
  • the product to be dispensed is, in particular, a liquid product, more or less viscous, or else a gelled product.
  • the dispensing nozzle is a spray nozzle.
  • the security device preferably comprises a hoop secured to a retaining element mounted to slide in translation on the neck, which neck has an annular projection extending radially outwards, the elastically compressible annular means being placed between the neck and the projection and pressing against the retaining element.
  • the retaining element is a ring provided with securing means cooperating with complementary securing means carried by the hoop, making it possible to fix the dispensing head on the ring.
  • the annular, elastically compressible retaining means may be formed, for example, by a helical spring made of metal or plastic, or else by a cylindrical sleeve made of elastomeric material.
  • the dispensing head comprises a retaining flange, sandwiched between the annular projection of the neck and an internal surface, of the hoop, ensuring the seal with respect to the propellant.
  • the bottom of the container can be fitted with an intake valve or propellant filling valve.
  • an intake valve or propellant filling valve To fill the container with propellant gas, the bottom of the container can be fitted with an intake valve or propellant filling valve.
  • the propellant gas is advantageously chosen from conventional propellants, such as hydrocarbons and liquefiable chloro- or fluoro-hydrocarbons and compressible gases, such as compressed air, nitrogen, carbon dioxide, etc.
  • the push button is pivotally mounted with a covering cover, of which the hoop is a part.
  • a covering cover of which the hoop is a part.
  • Figure 1 is a schematic axial section of a dispensing container according to the invention, the product to be dispensed being under pressure and can be dispensed using a valve.
  • FIG. 2 represents an enlarged axial section of the magnifying glass B of FIG. 1, the internal pressure of the container being normal.
  • FIG. 3 represents an enlarged axial section of the magnifying glass B of FIG. 1, the container being under overpressure.
  • Figure 4 shows a section similar to that of Figure 2, of an alternative embodiment.
  • a liquid dispensing container according to the invention can be seen, generally designated by the reference 1.
  • This dispensing container comprises a tank 2 of cylindrical shape having an axis of revolution A and provided with a concave bottom 3 comprising a valve 9 unidirectional propellant gas intake.
  • the tank 2 is made of one-piece aluminum.
  • this valve is shaped so that it can be connected to the outlet of an air compressor.
  • the tank 2 On the side opposite the bottom, the tank 2 has a top 5, in the form of a warhead, forming part of a dispensing head.
  • the top 5 is extended by a cylindrical skirt 51, the free end 51a of which is shaped as an annular bead. On this bead is fixed, by crimping, a cup 15 carrying a distribution valve 10.
  • the body of the valve 10 passes through the top 5, so that one of its ends 10a is located inside the tank 2.
