Definitions

  • the present invention relates to a push-button nozzle with multiple jets and closure, intended to equip a sprayer or a manual dispenser of fluid product.
  • Such push-pieces are used in particular for projecting a pharmaceutical product into the nose of a patient, but can also be used for other applications.
  • a technical problem which arises with all the push-pieces is to prevent the contact of the product contained in the push-piece with the outside air, in order to prevent drying of the product, its oxidation by the oxygen of the air or product pollution.
  • European patent application No. 0129643 describes a push-button comprising a cylindrical conduit provided with an outlet end comprising an outlet orifice and in which slides a piston secured to a needle directed towards the outlet orifice , the piston being elastically biased towards a position where the needle closes the outlet orifice and can be pushed back into an open position of the outlet orifice by the pressure of a fluid to be sprayed.
  • the present invention aims to solve these technical problems. It should be noted that such push-pieces are generally disposable after the product reserve of the spraying device has been used up. The technical solution adopted must therefore necessarily be inexpensive.
  • the present invention therefore relates to a push-button for a fluid dispenser comprising a chamber provided with an outlet and at least one cylindrical part having an axis of symmetry, a piston secured to a means for closing the outlet. sliding in said cylindrical part, said piston being urged by an elastic means so as to close the outlet by the closing means, and said piston being able to be pushed back by the pressure of the fluid product emitted by a distributor of so as to open said outlet, characterized in that the outlet of the push-piece is constituted by three outlet orifices, the piston is extended towards said outlet orifices by a rod having a certain flexibility, and the closure means is constituted by three valve stems integral with the stem, each having an end adapted to close an outlet orifice.
  • the rod has a certain flexibility in bending.
  • the push-piece has a cylindrical conduit extending towards the outlet orifices the cylindrical part in which the piston slides, and the valve stems are formed on radial ribs which extend from the rod and which slide with a certain play in the cylindrical conduit.
  • the push-piece end piece may further comprise a bottom wall in which the outlet orifices are formed, said bottom wall having an interior surface, or directed towards the valve stems, composed of three conical surfaces each converging towards a outlet, and of concavity turned towards said valve stems.
  • each valve stem is in the shape of a hemisphere and is applied in a sealed manner against a conical surface surrounding an outlet or else the end of each valve stem is planar and each outlet is surrounded by a flat facing a flat end of the valve stem, said flat being parallel to said flat end.
  • the push-piece has a hollow body comprising an outlet end in which the outlet orifices are formed, and an open end in which a socket is fitted, said socket having a bottom which closes the open end of the body and which is extended towards the outlet end by a solid part, then by a cylindrical wall in which the piston slides.
  • the massive part of the socket has a blind bore for receiving an actuating rod of the distributor serving for the emission of the product, the bore communicates with a lateral channel opening into an external groove of the socket which itself opens , through an opening in the cylindrical wall of the sleeve, between the piston and the outlet end of the body.
  • said massive part of the sleeve can be pierced with a vent channel which opens out between the piston and said massive part and which communicates with the atmosphere.
  • the push-piece can include a frustoconical body 1 which can be molded in plastic material, admitting an axis of revolution 2 and extending between an open end 3 and an outlet end 4, of smaller diameter at the end 3.
  • the end 3 has a cylindrical inner recess 8, advantageously provided with an inner peripheral lip 8a.
  • the recess 8 is extended towards the end of the sorb 4 by a first cylindrical conduit 9 of diameter less than the diameter of said recess 8, and said first cylindrical conduit 9 itself extends by a second cylindrical conduit 10 of diameter less than the diameter of said first cylindrical conduit 9, to a bottom wall 4a of the outlet end 4.
  • the bottom wall 4a is crossed by three outlet orifices 5 distributed at 120 degrees from each other around the axis 2 and equidistant from the axis 2.
  • the outlet orifices 5 can be inclined on the axis 2 so as to produce divergent jets when a product is emitted by the push-button.
  • the bottom wall 4a further comprises an interior surface divided into three conical surfaces 11 with axes parallel to the axis 2 each converging towards an outlet orifice 5, and of concavity turned towards the end 3 of the body 1.
  • the open end 3 of the push-piece can have a support ring 7 extending radially outwards, allowing a user to actuate the push-piece with two fingers.
  • the open end 3 of the push-piece can have a skirt 6 extending axially in the direction opposite to the end 4, so as to surround a pump or a spray valve on which the push-button.
  • a socket 20 which can be molded in plastic material, extending between a bottom 21 and an open end 22, and of outside diameter equal to the diameter of the first cylindrical conduit 9, is fitted tightly into said cylindrical conduit 9 and occupies the entire length of said conduit 9.
  • the bottom 21 of the sleeve 20 is extended externally by a crown 23, of complementary shape to the cylindrical recess 8 of the body 1, fitted into said cylindrical recess 8.
  • the crown 23 has a peripheral groove 23a, of shape complementary to the lip 8a, in which said lip 8a is snapped when the crown 23 is fitted into the cylindrical recess 8.
  • the sleeve 20 comprises a cylindrical cavity 24, centered on the axis 2, which extends over part of the length of said sleeve, between a solid part 25 and the open end 22.
  • This cylindrical cavity is delimited by a wall lateral cylindrical 24a having an internal diameter equal to the internal diameter of the cylindrical duct 10.
  • the massive part 25 of the sleeve 20 has a blind central bore 26 which opens onto the bottom 21 of the sleeve 20.
  • the bore 26 comprises a first cylindrical part 26a then a second cylindrical part of reduced diameter 26b, delimited by a shoulder 26c.
  • the portion 26b of the bore 26 communicates with a lateral lateral channel 27, which opens into an external groove 28 of the sleeve 20, parallel to the axis 2.
  • the groove 28 extends from the lateral channel 27 to the the open end 22 of the sleeve 20, where the cylindrical side wall 24a of said sleeve has an opening 29 which communicates said groove 28 with the cylindrical cavity 24 of the sleeve.
  • the massive part 25 of the sleeve has a non-central vent channel 30 which passes through said massive part parallel to the axis 2, and which communicates the cylindrical cavity 24 with the atmosphere.
  • the push-button according to the invention also comprises a piston 31 sliding in the cylindrical cavity 24 of the sleeve and extended towards the outlet end 4 of the push-button by an axial rod 32 having a certain flexibility in bending .
  • the rod 32 extends from the piston 31 to an end 33 close to the outlet end 4, said end 33 comprising three radial ribs 34 distributed at 120 degrees from each other around the axis 2, which slide with a certain clearance in the second cylindrical duct 10 of the push-piece (see FIG. 2).
  • Each rib 34 comprises a valve stem 35 of small diameter, disposed at the same distance from the axis 2 as the outlet orifices 5 of the push-piece, and which extends parallel to the axis 2 in the direction of the outlet end 4 of the push-piece until an end 36 adapted to close an outlet orifice 5.
  • the three valve stems 35 are of identical length and form with the three ribs 34 a rigid assembly.
  • the piston 31, the stem 32, the ribs 34 and the valve stems 35 can be molded from plastic.
  • a helical spring 37, or any other elastic means formed for example with the solid part 25, is disposed between the solid part 25 of the sleeve 20 and the piston 31, so as to elastically stress the assembly formed by the piston 31, the stem 32, the ribs 35 and the valve stems 35 towards the outlet end 4.
  • valve stems 35 are pushed against the bottom wall 4a and are guided towards the outlet openings 5 by the three cones 11 which constitute the inner surface of said bottom wall: if, during assembly of the push-piece, the relative angular arrangement of the body 1 and of the piston 31 is such that the three valve stems 35 do not are not opposite the three outlet orifices 5, the elastic stress of the valve stems 35 against the cones 11 in fact causes a rotational movement of the assembly formed by the piston 31, the rod 32, the ribs 34 and the rods valve 35 , at the same time as this assembly is pushed towards the outlet end 4, until the ends 36 of the three valve stems 35 respectively close the three outlet orifices 5.
  • the mounting of the push-button does not therefore does not require precise angular positioning of the assembly formed by the piston 31, the rod 32, the ribs 34 and the valve rods 35 relative to the body 1: this assembly is therefore simple and requires only conventional tools.
  • the ends 36 of the valve stems 35 may have a rounded hemispherical shape, which collaborates with the cones 11 to close the outlet orifices 5 in a sealed manner.
  • the ends 36 ′ can be flat and perpendicular to the axis 2, and the bottom wall 4a of the push-piece can have flats 38 surrounding each outlet orifice 5, in with regard to said ends 36 ′ of the valve stems 35, said flats 37 having a width identical to that of the ends 36.
  • the ends of the valve stems 35 may nevertheless have any other shape, without departing from the scope of the invention.
  • valve stems 35 may have slightly different lengths or the inner surface of the bottom wall 4a have cones 11 which are not all at exactly the same height along the axis 2.
  • the three ends 36 of the valve stems 35 are in all cases in sealed contact with the bottom wall 4a, each closing an outlet orifice 5: in fact, under the action of the spring 37, the rigid set formed by the three ribs 34 and the three valve stems 35 can be oriented by bending deformation of the stem 32, so that each end of the valve stem closes an orifice 5. This orientation, which places the ribs slightly oblique in the cylindrical conduit 10, is only possible thanks to the play between the ribs 34 and the cylindrical conduit 10.
  • the manufacturing tolerances to be made up by the orientation of the rigid assembly formed by the three ribs 34 and the three valve stems 35 are generally small, so that the angular deviation of the ribs 34 is small: it therefore suffices to have a low clearance between said ribs 34 and the cylindrical conduit 10 to allow the desired orientation of the ribs 34.
  • valve stems 35 cease to be perfectly parallel to the axis 2.
  • ends 36 of the valve stems are hemispheres (FIG. 1) which bear against the cones 11, this does not interfere with the sealing of the contact between each end 36 in a hemisphere and each cone 11.
  • ends 36 ′ are flat (FIG.
  • the push-button according to the invention can be used on a manual spraying or dispensing pump, or on an aerosol valve, comprising a hollow actuating rod (not shown) which is used for the emission of a fluid product .
  • the actuating rod is fitted into the first cylindrical part 26a of the blind bore 26, in abutment against the shoulder 26c.
  • the shoulder 26c presses on the actuating rod of the pump or of the spray valve, so that fluid is emitted by said actuating rod in the second cylindrical part 26b of the blind bore 26, at a relatively high pressure.
  • the product passes through the lateral channel 27, the groove 28, the opening 29, and enters the cylindrical chamber 39.
  • the piston 31 Due to the pressure of the product, the piston 31 is pushed back towards the solid part 25 of the sleeve 20 by driving with it the valve stems 35, which open the outlet orifices 5 (cf.: FIG. 3). The product is then emitted through the three outlet orifices 5.
  • the piston 31 When the piston 31 is pushed back towards the solid part 25 of the sleeve, part of the air comprised between said piston 31 and said solid part 25 is expelled through the channel d '' vent 30.
  • the product When the user stops pressing on the crown 7, the product ceases to be emitted by the actuating rod of the pump or of the valve, so that the pressure in the cylindrical chamber 39 drops.
  • the spring 37 then pushes the piston towards the outlet end 4, until the three valve stems 35 close the three outlet orifices 5, as explained above.
  • the product contained in the push-piece is then isolated from the atmosphere, and therefore protected from drying, oxidation or pollution. It should be noted that the spring 37, generally metallic, is not in contact with the product: there is therefore no risk of polluting the product either.
  • the push-button according to the invention could also be mounted not coaxially with the actuating rod of the pump or of the valve as in the example presented, but with the axis 2 perpendicular to the actuating rod.
