Definitions

  • the present invention relates to a manually controlled spray-metering device of the type comprising a mechanical piston and plunger pump ensuring the suction of a liquid to be sprayed which is delivered to a spray nozzle.
  • a manually controlled spray-metering device of the type comprising a mechanical piston and plunger pump ensuring the suction of a liquid to be sprayed which is delivered to a spray nozzle. Examples of embodiment of such devices are described in particular in EP-A-0025224 and FR-A-2374536.
  • such spray-dosing devices are intended in particular for the distribution of liquid or viscous products, in low doses, for example samples of perfumes or cosmetics or pharmaceutical products.
  • the BAUMANN patent DE-A-85608 describes a metering system for liquid products essentially comprising a pump of the mechanical type positioned at the neck of the container containing the product to be dispensed and in which the body of said pump is force-fitted into an intermediate piece which cooperates by means of an elastic sleeve with the neck of said container which encloses it, said body, extended by a lower part in the product to be dispensed, called a dip tube, the assembly being further provided at the level of the body of said pump with a vent hole for venting.
  • European patent EP-A-0 339 125 is also known, the latter describing a spray metering device for liquid or viscous products in which the mechanical type pump is positioned, with the help of an elastic member, in a container containing the product to be dispensed, the pump body having a shaped fitting zone allowing the pump body to be fixed in the neck of the container.
  • the upper part of the pump body ends in a flange which abuts on the neck of the container. It is also provided with a jacket force-fitted into the upper part of the pump body, this jacket ending in its upper part by a collar coming into abutment against the collar of the pump body.
  • the ring or clipping currently considered essential by a person skilled in the art to constitute the spray-metering unit, can be produced in various embodiments such as in particular screw-on rings, crimp rings, snap-on sleeves and other types of rings of known types.
  • the present invention therefore proposes to provide a metering device which does not have the drawbacks mentioned above of solutions according to the prior art and in which the mounting is carried out with tightening of the pump body in the neck of the container, without malfunction of the pump, by sealing the container and the pump without an intermediate seal, so as to precisely distribute very low doses, for example between 35 and 45 "l.
  • the vent hole is placed under a shoulder of the body which is provided between the upper cylindrical part of the latter, force fitted into the neck of the container and its lower part of reduced diameter.
  • the means for ensuring the escape of air during the fitting consist of a groove formed in the external cylindrical surface of the pump body on which the vent hole opens.
  • the spray-metering system comprises a jacket force fitted into the upper part of the body, this shirt ending at its upper part by a collar coming into abutment against the collar provided on said body.
  • the lower part of the pump piston is provided with a skirt which has an annular lip which, when at rest, is held under radial stress, said lip being wedged between a flange, provided at the lower end of the piston, and the inside of the body of pump, the vent hole is provided under the lip of said skirt, when the latter is at rest.
  • the spray-metering device comprises, in this non-limiting exemplary embodiment, a piston pump mechanism designated as a whole by the reference 14 which is positioned on the container 2, generally made of glass or plastic, containing the product to be vaporized, this container being surmounted by an internally smooth and cylindrical neck 7.
  • the piston pump 14 is provided with a dispensing plunger 1.
  • the body 3 of the pump mechanism is fitted inside the neck 7 of the container, as can be clearly seen in the drawing.
  • This body 3 is extended here in one piece, in its lower part, by a sampling tube 6 which is flush, as known, with the bottom of the container 2.
  • the upper part of the body 3 ends in a flange 12 which comes in abutment on the neck 7 of the container 2.
  • the external part of this body is cylindrical and smooth and it comes to tighten at the inside of the neck 7, as can be seen in the figures. Sealing is therefore achieved by fitting at this level, the pump body perfectly matching the inside diameter of the neck of the container.
  • the pump body 3 may preferably be made of injected thermoplastic material and of suitable quality in order to guarantee an intimate connection, therefore tight, by marrying, under elastic stress, the shape of the inside of the neck of the container.
  • the cylindrical part 15 of the body on which the tightening takes place is extended by a part 16, of cylindrical shape, the outside diameter of which is substantially smaller than that of the part upper body 15 and, in any case, smaller than the inner diameter of the neck.
  • a shoulder 10 is provided between the upper 15 and lower 16 parts of the pump body.
  • a lateral vent hole 9 opens onto the outside, this vent hole being located under the shoulder 10. The presence of this vent hole makes it possible to vent the pressure of the air which is generated inside the container 2 when the fitting of the pump body is carried out on the neck of the container.
  • this venting can be obtained by providing an external groove which is formed in the cylindrical surface of the pump body and on which said vent hole opens.
  • the pump operating mechanism tends to return, under the effect of an internal return spring 17, the rod 8 at the end of which the piston 18 of the pump is mounted, this rod being surmounted by the dispensing pusher 1.
  • a jacket 4 is provided which is force-fitted to the inside of the body 3 and which is surmounted by a collar 13 which abuts on the collar 12 of the body 3.
  • the holding of the shirt 4 in the body 3 can be reinforced by providing hooking means such as 5 , for example in the form of hooks and grooves engaged in each other and provided respectively on the opposite faces of the body 3 and of the jacket 4, as can be clearly seen in FIG. 1.
  • the inner surface of the body 3 and the outer surface of the jacket 4 are smooth and cylindrical in shape and they are tight.
  • the lower part of the jacket 4 constitutes the upper stop of the pump mechanism and this stop positions the high point of the stroke of the pump during operation. Consequently, the height of the jacket 4 constitutes a determining factor in the dose of products which can be vaporized by the device according to the invention.
  • the dimensions as well as the configuration of the shirt 4 can be chosen so that these constitute the covering of the neck of the container.
  • the rod 8 which, under the action of the push button 1, actuates the pump mechanism, slides freely inside the jacket 4 with sufficient play, as seen in FIG. 1.
  • the fitting action of the pump body inside the neck of the container can be carried out by applying a pressing force on the upper part of the dispensing plunger 1.
  • the dispensing plunger 1 can be of a diameter greater than that of the collar 13 of the jacket 4 or of the body 3 of the pump mechanism.
  • the height of the fitting is practically equal to the interior height of the neck 7 of the container 2.
  • the pump can operate without a seal system.
  • the lower part 22 of the piston 18 of the pump is produced so as to ensure a double function: the centering of the spring 17 and the end-of-travel stop on the ball 23 provided, conventionally, in the sampling tube 6 at the top of the latter.
  • the base of the piston coming into abutment on the ball, blocks the latter thus preventing any rise of the liquid during the slight overpressure due to the fitting.
  • this pump is similar to that of the piston pumps of the vaporizer-metering devices according to the prior art mentioned above and will not be described again. It will however be noted that the passage of the liquid in the channel 23 of the pump body, and through the transverse channel 24 can be carried out either by deformation or by lifting of the skirt 19.
  • the device according to the present invention is preferably applied to small capacity containers intended in particular for the market for the sampling of perfumes and cosmetics.
  • the pump body can have a diameter of 5 mm compatible with a tight fitting of this body inside the necks of drawn glass containers made for this use, but whose closure is the present time provided by a simple plug making it impractical to use such sample tubes.
  • the device according to the invention can therefore be substituted for the current stopper of these sample tubes making it possible to provide a sprayed restitution of the perfume sample or a restitution in "nuts" for products with a viscous consistency, in particular cosmetic products such as gels, oils, creams or milks.
  • the invention can be applied to containers of larger capacity and to necks of larger diameter.
