Definitions

  • the invention relates to a valve for an aerosol canister, a valve of the kind which allows the spraying of a product contained under gas pressure in the canister and which comprises a body fixed on the canister and projecting inwards from it. container, and an actuating rod, accessible from outside the container, and capable of being moved, by the action of a user, to control the opening of the valve according to the preamble of claim 1.
  • the object of the invention is, above all, to provide a valve which makes it possible to solve this problem by automatically preventing any spraying when the pressure inside the can becomes lower than a predetermined pressure, considered as minimum to ensure a suitable spraying.
  • a predetermined pressure considered as minimum to ensure a suitable spraying.
  • the object of the invention is to provide such a valve which is of a simple and economical embodiment and which can be produced easily from conventional valves which does not make it possible to automatically prevent spraying from a certain minimum pressure.
  • a valve for aerosol can of the kind defined above is characterized in that the combination of the valve and the valve is such that, the valve body having an inlet and the valve comprising a tubular casing covering said inlet, the movable member of the valve is arranged in such a way that the passage of the product constituted by the inlet and the 'envelope can be closed, the valve opening only for a pressure, inside the tank, at least equal to the above predetermined limit.
  • the movable member for closing the valve consists of a ball; alternatively, this movable member can be constituted by a needle or any equivalent means.
  • the tubular casing is fixed to the valve body and has an orifice for communication with the interior of the container, this orifice comprising a seat for the movable closure member, the calibrated spring tending to apply this closure against this seat.
  • the valve according to the invention comprises a conventional standard valve, and the envelope of the valve is attached and fixed to the body of this conventional valve.
  • the cover of the valve is provided with a connection tip coaxial with the communication orifice for the connection of a dip tube.
  • An additional gas outlet opening transversely, may be provided in said valve casing, beyond the seat of the ball, on the side of the interior of the container.
  • valve casing When the valve is made from a standard valve whose body has an extension for connection to a dip tube, the valve casing also covers this extension and the calibrated spring is arranged around this extension, coaxially, so as to lean against the end of the standard valve body.
  • the determined pressure, from which the valve opens is of the order of 2.105 Pa (2 bars).
  • the invention also relates to an aerosol can equipped with a valve as defined above.
  • Figure 1 of these drawings is an axial section, with external parts, of a valve according to the invention, the actuating rod being in the closed position.
  • Figure 2 shows, similarly to Figure 1, the valve while the rod is in the open position, the pressure in the container being greater than the predetermined limit.
  • FIG 3 finally, shows the valve, similarly to Figure 2, while the pressure in the container is below the predetermined limit.
  • valve 1 for an aerosol can (not shown) containing a liquid product under gas pressure.
  • the valve 1 comprises a body 3 fixed to the container by a crimp 4 suitable for trapping in a cup 2 provided on the container, a portion 5, of larger diameter, provided at the upper end of the body 3.
  • This part 5 is in abutment against a sealing washer 6 which is itself in abutment against a flange 7, of the dish 2, the mean plane of which is orthogonal to the axis of the container.
  • the cylindrical body 3 projects towards the inside of the container and includes a conventional valve mechanism, not shown.
  • a valve actuation rod 8 is slidably mounted in the body 3, in the axial direction A.
  • the rod 8 comprises a longitudinal blind hole 9 opening upwards, and into which opens, in the vicinity of the bottom, a radial channel 10 communicating with the external surface of the rod 8.
  • the rod 8 is recalled, in the rest position shown in Figure 1, by elastic means (not shown). In this position, the channel 10 is located substantially mid-thickness of the washer 6 and is closed by the internal cylindrical wall of this washer.
  • the body 3 is that of a standard valve and has an extension 11, of smaller diameter, provided with an inlet channel 12.
  • the extension 11 is provided for connection to a dip tube (not shown) extending towards the bottom of the can.
  • the control of the insertion of the rod 8 into the body 3 is ensured by action on a push button (not shown), so that the channel 10, as shown in FIG. 2, opens into a volume located at below the sealing washer 6.
  • a valve 13 with a movable closure member constituted by a ball 14 is provided inside the container and is combined with the standard valve. It is clear that the movable member for closing the valve could be constituted by a needle, or other equivalent means.
  • the valve 13 comprises an envelope 15 fixed to the body 3 so as to cover the extension 11 and to cover the inlet 12.
  • the casing 15 comprises an orifice 16 for communication with the interior of the container, this orifice 16 comprising a frustoconical seat 17 for the ball 14.
  • This ball is subjected to the action of a calibrated spring 18.
  • the spring 18 is a helical spring arranged around the extension 11, coaxially, so as to bear against the end 19 of the valve body 3. The spring 18 tends to apply the ball 14 against the seat 17 and thus closing the orifice 16.
  • calibrated spring must be understood in a broad sense and includes any tared elastic means, acting like a spring, in particular a leaf spring type tinsel.
  • the envelope 15 of the valve is provided with a nozzle 20, coaxial with the orifice 16, for the connection of a not shown dip tube.
  • the end piece 20 comprises a channel 21 into which an additional gas outlet 22 opens through a radial passage provided on the side of the orifice 16 opposite the ball 14, the additional gas outlet 22 communicating the channel 21 and the volume inside the container.
  • the spring 18 is calibrated so as to hold the valve 14 against the seat 17 as long as the pressure difference between the interior of the container and the interior chamber of the envelope 15 is less than a value of the order of 2 bars.
  • the interior of the envelope 15 is placed in communication with the atmosphere by the channel 10 and the pressure, in this envelope 15, becomes lower than the gas pressure prevailing in the container.
  • this gas pressure is sufficient, it exerts on the ball 14 a force greater than that of the spring 18 and therefore separates the ball 14 from its seat 17 as illustrated in FIG. 2.
  • the product to be sprayed can then pass through the channels 21, the orifice 16, the inlet 12, the channel 10 and the hole 9 to exit, through the nozzle of a dispensing head not shown, in the form of sprayed droplets in the air.
  • the valve according to the invention thus makes it possible to guarantee correct distribution of the product.
  • the distribution can resume only after the pressure has risen to a value high enough to cause the ball 14 to come off.
  • This pressure rise can be obtained, in the case of refillable cans, by a propellant gas refill operation.
  • This valve is simple and economical to produce and can be obtained by rapid modification of a standard standard valve.
