Definitions

  • the present invention relates to a new valve, as well as a container, in particular of the disposable type after use, equipped with such a valve.
  • the first uses containers of the perforable type, generally constituted in the manner of a can, by means of a cylindrical body closed at one end by a convex wall, filled with liquefied butane , then closed at the other end by a concave bottom crimped onto said body.
  • valve cartridge uses containers of the type used for aerosol dispensers. These cartridges generally comprise a box constituted by a cylindrical body with crimped concave bottom, possibly a dome mounted on the body, and a valve crimped in a sealed manner, for example after filling, on the box.
  • This valve is of the "female” type, that is to say has no means allowing the user to open it directly, for example a rod emerging from the valve.
  • the devices with a perforable cartridge are distinct in terms of the use of devices with a valve cartridge, and that in particular a perforable cartridge, without valve, cannot be used on a device with a valve cartridge. .
  • valve cartridges that can be used with a perforable cartridge device. These were cartridges fitted with traditional aerosol valves, of the "female" type as described above.
  • This sealing supposes a coaxial support of the annular seal of the tubular valve, with the central boss of the valve cup.
  • this boss does not compensate for any dispersion of coaxiality, due to the manufacturing tolerances of the cup and / or the gas intake head of the device.
  • This sealing also supposes to keep the valve in the operational state, in its closed position, since the user is in the habit of removing the cartridge, not necessarily empty, from his device, after use of the latter.
  • using a device with a perforable cartridge with a valve cartridge amounts to using the perforating tip as a tubular plunger.
  • said point then behaves like a machining tool , and can permanently damage the axial boss and / or the valve flap, and therefore the sealing of the latter, in particular as a function of the concentricity deviations.
  • the present invention relates to a new valve allowing the safe use of a cartridge fitted with such a valve with a device with a perforable cartridge.
  • a valve according to the present invention differs from a traditional aerosol valve, by a particular shape of the axial boss of the cup, adapted to a particular dimensioning of the central opening of said boss, and of the other functional elements. of the valve linked to this opening.
  • first of all the central opening of the axial boss of the valve is relatively wide, having regard to that of traditional aerosol valves, and is at least equal to 4 mm in diameter.
  • the diameter of the central bore of the transverse joint, and on the other hand the internal diameter of the peripheral lip of the valve are beyond those encountered for a traditional aerosol valve; and it is the same for the overall diameter of the axial boss.
  • the top of the axial boss has on the outside a concave face, of radial extension from the central opening, and on the other apart the transverse joint follows the concave shape of the aforementioned vertex.
  • the largest diameter of the central opening and of the functional elements of the valve which are linked to it, allows penetration of the perforating point, without destruction, within the limits of the coaxiality deviations of the point.
  • the seal between the valve lip and the transverse joint would normally be deteriorated, since it would be carried out flat, according to an annular crown of larger diameter. Thanks to the concave shape according to the invention, and from the top of the axial boss and the transverse joint, the same seal is effected in a circle, corresponding to the line of contact between the edge of the valve lip and the joint. transverse; a good specific seal is thus obtained, compensating for the increase in diameter, and this for a comparable bearing force of the spring.
  • this concave shape of the axial boss allows self-centering of the tubular sealing plunger, particularly favorable to the overall sealing of the cartridge / device connection.
  • valve described above has dimensional and functional characteristics, differentiating it from traditional valves for aerosol containers.
  • the diameter of the circle inscribed in the central opening (1e) is at least equal to 4 mm, and is for example of the order of 5.2 mm.
  • the peripheral lip (4b) of the valve (4) has an internal diameter at least equal to 4.5 mm and is for example of the order of 5.2 to 5.7 mm. Still in correspondence, the overall outside diameter of the boss (1c) is at least equal to 10 mm, and is for example equal to 11.5 mm.
  • the central hole (3a) of the transverse joint (3) has a diameter (that of the inscribed circle), less than that of the central opening (1e), so that its edge emerges from that the aforementioned opening; this diameter is for example of the order of 4.4 mm.
  • the seal (3) can act as a guide for the perforating tip of a valve cartridge apparatus, when the latter enters the central opening (1e).
  • the concave face (1d) of the boss (1c), cup-shaped is perfectly uniform and smooth, from the flat edge of the central opening (1e) to the peripheral rim of the same boss (1c ), rounded towards the bottom of the cup; this is unlike traditional valves, the central opening of which has an upwardly turned rim, having an axial section in the form of a hook.
  • This characteristic makes it possible to avoid any alteration or deterioration of the annular seal of a device with a perforable cartridge, when the latter comes into contact with the top (1d) of the boss (1c), as described below.
  • the thickness of the central part (4a) of the valve (4) is at least equal to 2 mm, which allows the latter to withstand any "machining", under the effect of the movement in translation and in rotation of the tip perforator of a perforable cartridge device.
  • the spring (5) determines a stroke of the valve at least equal to 3 mm. This stroke makes it possible to accommodate the movement of the valve (4) in the most unfavorable case corresponding to maximum penetration of the perforating tip into the opening (1e), under the effect of dimensional dimensions overlapping along the axis of the valve.
  • FIG. 2 represents a container of the disposable cartridge type with valve, comprising a body (6) or box in the opening of which is fixed, by crimping, in a leaktight manner using the seal (7), a valve according to the present invention, and previously described with reference to Figure 1.
  • This container contains a charge of liquefied butane (8).
  • the instructions for use are absolutely identical to that described above, with the difference that a valve cartridge according to the invention can be removed at will from an apparatus, without it is necessary to pay attention to whether the cartridge is empty or not.
  • the perforating tip (14b) is capable of machining, during its descent in rotation, the central part (4a) of the valve, without this being able to lead to deterioration of the valve.
