- an aerosol can adapted to this pressurizing device comprising a closed enclosure containing said aerosol and air, this enclosure being equipped with a spraying device arranged at its upper end, with a base arranged to receive said filling nozzle of the pressurizing device, this base being provided with a non-return valve of the pressurized air contained in said box
- 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 ' 8.08 407 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 providing a device for pressurizing aerosol cans and cans adapted to this device, which are effective, economical, practical and which completely eliminate the problem of pollution due to gases. propellants.
- the device according to the invention is characterized in that the coupling means are arranged to cooperate with said means for switching on and off the compressor and switching on the compressor when the box is put in place. aerosol in said housing, and to trigger it when the air pressure inside the box has reached a predetermined value.
- said coupling means comprise a locking device for holding the aerosol can in said housing housing until the predetermined pressure value is reached.
- Said locking device preferably comprises 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 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 through said filling nozzle.
- 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 an engagement switch and triggering of the compressor, so that this compressor is engaged when the lever is brought into its second position and that it is triggered when the lever is brought into its first position.
- the aerosol can is characterized in that said erbase comprises hooking means arranged to cooperate with said hooking means of said pivoting lever of the coupling means.
- said base has an annular groove arranged to cooperate with said attachment means of said pivoting lever of 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 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, with 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 exist commercially 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. can be connected to a cigarette lighter of 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 allows compressed air to be obtained 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.
- Figures 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.
- this platform 20 In the center of this platform 20 is 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.
