Definitions

  • the present invention relates to a combination of an aerosol can with a pressurizing device, this box comprising a closed enclosure containing said aerosol and air, this enclosure being equipped with a spraying device arranged at its end. upper, of a base arranged to receive a filling nozzle of the pressurizing device, this base being provided with a non-return valve of the pressurized air contained in said box, the pressurizing device comprising a housing comprising a housing for receiving an aerosol can and containing an electric pump constituting an air compressor, means for switching on and off of this air compressor, and coupling means for momentarily coupling the can aerosol with said compressor.
  • a more satisfactory solution consists in reloading an aerosol can with pressurized air when the internal pressure of the can is no longer sufficient to propel the substance of the can.
  • German publication DE-A-3 800 194 describes a device for pressurizing an aerosol can by means of a compressor comprising a filling nozzle and a switch.
  • the defect of this device comes from the fact that it has neither means for coupling the compressor housing to the aerosol can, nor means for controlling the pressure inside the can.
  • the user must therefore hold the box in place manually by pressing it against the bottom to engage the filling nozzle in a non-return valve of the aerosol can, and thus keep the valve open during filling.
  • the user must also remove the aerosol can when he considers that the internal pressure of the can is adequate to allow spraying of the substance, i.e. neither too low nor too high, which could be dangerous.
  • the device described by the utility model DE-U-8 808 407 comprises a frame comprising a compressor with a compressed air tank and a filling nozzle, and an upper arm.
  • the upper arm presses the can against the bottom. This has the effect of opening a non-return valve located at the bottom of the box and engaged in the filling nozzle, which brings the compressed air tank into contact with the inside of the box. The pressure in the tank and in the box is balanced.
  • This device has several faults. It is particularly bulky and therefore impractical.
  • due to the presence and function of the upper arm it only allows the use of boxes which have a determined height. An additional defect of this device comes from the fact that the interior of the box remains in contact with the compressed air reservoir as long as the box remains in the support. Here again, the user must himself remove the box from its support when it considers that the desired internal pressure has been reached.
  • the present invention proposes to overcome all these drawbacks by making a combination of an aerosol can with a pressurizing device, efficient, economical, practical and which completely eliminates the problem of pollution due to propellant gases.
  • the combination according to the invention is characterized in that the base of the can and the pressurizing device comprise locking means for holding the aerosol can in said housing of the housing and in that these coupling means are constituted by means for switching on the compressor when the aerosol can is placed in said housing, and for triggering it when the air pressure inside the can has reached a predetermined value.
  • Said device locking means preferably comprise a lever provided with means for hooking the aerosol can.
  • said lever is housed in an inclined recess formed in said housing, also containing a thrust spring tending to bring said lever into a first high position, defined by a stop member which limits the travel of this lever.
  • the lever comprises a latching notch formed on its lateral face, this notch being arranged to cooperate with a locking pawl of this lever in a second low position in which the thrust spring is compressed.
  • Said pawl may be integral with a piston, one side of which is subjected to the pressure of a calibration spring and the other side of which is subjected to the pressure of the pressurized air contained in the aerosol can.
  • Said piston is advantageously housed in a cavity formed in the housing and divides this cavity into two chambers, one of which contains said calibration spring and the other of which communicates with the aerosol can.
  • the chamber containing the calibration spring has an axial groove arranged to allow the free escape of the gas under pressure when the stroke of the piston exceeds a predetermined value.
  • said lever may include means for cooperating with a switch for switching on and off the compressor, so that this compressor switches on when the lever is brought into its second position and it triggers when the lever is brought into its first position.
  • Said base advantageously comprises latching means arranged to cooperate with said latching means of said lever of the coupling means.
  • said base comprises an annular groove arranged to cooperate with said means for attaching said lever to the coupling means.
  • said base is crimped into a central opening of the enclosure, the part comprising the non-return valve being disposed inside the enclosure and the part comprising said annular groove being disposed at the outside of this enclosure.
  • the device 10 for pressurizing an aerosol can 11 mainly comprises a housing 12, the upper face of which is equipped with a measuring instrument 13 which indicates the pressure of the pressurized air which is injected by the device 10 into the aerosol can 11.
  • the aerosol can is a completely conventional can as a whole, but the bottom of which is equipped, as will be explained in more detail below, means allowing an injection of pressurized air which can be carried out in different ways.
  • the housing 12 contains an electric pump constituting an air compressor 14 consisting on the one hand of a cylinder 15 and a drive motor 16 and on the other hand of minus a compression piston.
  • air compressor 14 consisting on the one hand of a cylinder 15 and a drive motor 16 and on the other hand of minus a compression piston.
  • These compressors are commercially available and are commonly used for various applications such as, for example, inflators for automobile wheels, swimming buoys, air mattresses, inflatable boats, etc., which are currently supplied with electrical energy through a special outlet which can be connected to a cigarette lighter in a motor vehicle. It is understood that any other miniaturized compressor can be used to constitute a source of pressurized air, provided that this compressor makes it possible to obtain compressed air at a pressure at least equal to 8 bars.
  • the housing 12 comprises a housing 17 intended to receive the rear end of the aerosol can.
  • the pressurizing device 10 is equipped with a filling nozzle 18.
  • Coupling means in the form of a lever 19 are provided for coupling the pressurizing device and the aerosol can positioned in the housing 17.
  • FIGS 3 and 4 show a first embodiment of the coupling means associated with the filling nozzle and the aerosol can.
  • the housing 17 defines a platform 20 of circular shape whose diameter is slightly greater than the diameter of the bottom 21 of the aerosol can 11.
  • the filling nozzle 18 which is in the form of a substantially cylindrical part traversed by an axial channel 22, and the peripheral surface of which is fitted with a seal 23 housed in an annular groove 24.
  • the channel 22 has the function of conveying air under pressure generated by the compressor towards the distal end 25 of the nozzle 18, and finally to an enclosure defined inside the aerosol can 11.
  • the bottom of the aerosol can is equipped with a base 26 provided with a ball valve 27 or any other form of suitable non-return valve, and having a cavity 28 whose shape and dimensions correspond to those of the end piece 18 so that the end piece can be engaged in a sealed manner inside this cavity 28.
  • This base of generally cylindrical shape, is engaged in an appropriate central opening formed in the bottom 21 of the aerosol can, and is fixed to this bottom by means of a crimping ring 29.
  • An annular part 30 comprising an annular groove 31 is fixed to the external part of the base 26 and makes it possible to ensure , with a lever 32 integral with the housing of the pressurizing device, the coupling between this device and the corresponding aerosol can.
  • This lever 32 has at its upper end a spout 33 intended to engage in the annular groove 31 and to constitute with the latter means for hooking the lever 32 and the annular part 30, in other words ensuring the coupling between the aerosol can and the pressurizing device of the latter.
  • the lever 32 is housed in an inclined recess 34 formed in the housing 12 and containing a thrust spring 35 which tends to bring this lever into its high position represented by FIG. 3.
  • a stop member constituted by a pin 36 allows, in conjunction with a longitudinal recess 37 to limit the stroke of this lever between two positions, a first high position represented by FIG. 3 and a second low position represented by FIG. 4.
  • This lever also comprises a snap-in notch 38 formed on its lateral face, this notch being arranged to cooperate with a locking pawl 39 secured to a piston 40 housed in a cavity.
  • This piston 40 delimits a chamber 41 in which a calibration spring 42 is arranged and a second chamber 43 which communicates by a duct 44 with the supply duct 22 of the pressurized air formed in the nozzle 18.
  • the lever 32 When the aerosol can 11 is brought into position on the nozzle 18, the lever 32 is pushed towards its low position. The spout 33 of this lever engages in the annular groove 31. When the low position is reached, the pawl 39 engages in the latching notch 38, which has the effect of preventing the lever 32 from rising under the effect of the thrust exerted by the spring 35. In this low position, a compressor start switch is automatically engaged, which has the effect of starting the production of compressed air which is injected through the end piece 18, base 26 and ball valve 27 inside the enclosure formed in the aerosol can 11.
  • the calibration spring 42 is adjusted to a predetermined tension, so that the piston 40 is subjected to two balanced forces when the pressure of the compressed air reaches approximately 8 bars.
  • the compressed air injected into the enclosure of the aerosol can is also at this pressure.
  • the piston 40 is pushed back in the opposite direction to that in which the calibration spring 42 tends to push it back.
  • the pawl 39 emerges from the notch latching 38, which releases the lever 32.
  • this lever is raised to return to its high position by pushing the aerosol can at the same time and by triggering the start-up switch compressor.
  • the ball valve 27 closes, which has the effect of trapping the air contained inside this can. .
  • a safety device is provided to prevent dangerous overpressure in the can.
  • an axial groove 45 is provided in the chamber 41 to ensure the free escape of air if the piston 40 moves back beyond a certain predetermined stroke. This safety is also effective if, for any reason, the compressor does not start when the maximum pressure is reached.
  • the piston 40 is made integral with a plate 46 by means of a screw 47.
  • This plate 46 has a notch 48 located in look of an access recess 49 formed in the base of the housing.
  • the user can then manually push the plate 46, using a suitable tool such as a screwdriver, to bring the piston and the pawl into their withdrawn position which allows the release. lever 32 and release of the aerosol can.
  • This embodiment has the advantage of allowing the use of compressed air as a propellant for the substances to be sprayed in the form of an aerosol. As a result, the ecological and economic problems mentioned above are resolved in a simple and effective manner.
