Definitions

  • the present invention relates to a device for dispensing a fluid product, that is to say in the form of a liquid or a more or less viscous paste or cream.
  • the fluid product can be dispensed in spray form, that is to say in the form of fine droplets, spray or aerosol or in the form of foam.
  • Many devices are known for dispensing a fluid product in spray form or foam. They generally comprise a container containing the fluid product to be dispensed, this container possibly being pressurized or not, and being provided with a device for dispensing the product (valve or pump).
  • This distribution member conventionally contains a part movable in translation which is actuated by pressing.
  • the movable part of the dispensing member generally consists of a dispensing head comprising a channel, a product dispensing nozzle and a pusher on which is pressed to push in the movable part of the dispensing member.
  • the user can act directly manually on the dispensing head but, to reduce the effort necessary to actuate the dispensing member, it is known to use a lever.
  • the dispensing head and the container are generally capped with a cover on which the lever is articulated, the articulation being able to be constituted by a film hinge, the lever then being molded in one piece with the cover, or be constituted by another system, the lever and the cover forming two separate parts.
  • Said lever is provided with a support element on the plunger of the dispensing head.
  • the pusher preferably has a flat upper surface, which is generally perpendicular to the axis of translation of the moving part. This pusher may include guide elements for the support element so as to prevent any lateral movement of said support element.
  • Said support element is located between the articulation of the lever on the cover and the free end of the lever on which the user presses.
  • An opening is, of course, made in the cover, vis-à-vis the spray nozzle of the dispensing head.
  • Distribution devices of this type are, for example, described in EP-A 0 402 636, FR-A 2 319 540; FR-A 2 675 403 describes a device as presented in the preamble of claim 1.
  • the support elements were constituted either by a needle, or by a cam having in section, in the plane of rotation, the shape of a segment of a circle, or by a sphere or a sphere cap.
  • This type of support element has the following drawback: the result of the forces applied by the user on the lever, and of the friction forces of the elements of the dispensing member on the sprayer itself, results in a deformation of the movable part of the dispensing member, which under the effect of this force no longer slides in a plane corresponding to the axis of the sprayer itself.
  • the force fulcrum slides on the plunger of the dispensing head and there is a modification of the support conditions.
  • FIG. 1 a device is shown comprising a movable part 1 moving in translation along the axis XX in a tubular element 2 coaxial.
  • a lever 3 is provided with a support element 4 constituted by a cam having in section the shape of a segment of a circle.
  • the support element 4 presses on the surface perpendicular to the axis XX of translation of the movable part 1 forming a pusher.
  • the theoretical force exerted Ft is perpendicular to the straight line joining the fulcrum to the articulation point, and it therefore forms an angle ⁇ with the axis XX.
  • the object of the invention is, in particular, to remedy these drawbacks.
  • cam support element a cam having in section, in a mean plane of rotation of the lever, a shape such as the force exerted. by the user is transmitted to the surface of the dispensing head at a constant point, located on the axis of translation of the movable part of the dispensing member or on a parallel to said axis of translation.
  • the present invention therefore relates to a device for dispensing a fluid product
  • a container provided with a dispensing member comprising a dispensing head movable in translation and provided with a pusher, and a cover covering the container.
  • the dispensing head, cover on which a lever is articulated the lever carrying a support element capable of pressing on the pusher of the dispensing head to depress the dispensing head of the dispensing member characterized by the fact that the bearing element is a cam whose cross section in the plane of rotation of the lever is limited by an involute of a circle centered on the axis of articulation of the lever, this axis of articulation being situated above of the plane on which the pressing force is exerted on the pusher.
  • the point of application of the force is preferably located in the center of the plunger of the dispensing head, on the axis of translation of the movable head of the dispensing member. Under these conditions, the point of application of the force is located on the axis of translation of the movable part of the dispensing member. The deformations are thus reduced.
  • the axis of the articulation between the lever and the cover is formed by a film hinge.
  • the lever and the cover are molded in one piece. It is also possible to conform the lever and the cover into two separate parts, the articulation being formed by any conventional arrangement, for example by engagement of two pins made on the lever in corresponding recesses of the cover.
  • Figure 2 shows in partial section an assembly 101 according to the invention comprising a container 102 (partially shown) on which is fixed a pump 103 whose movable part consists of a dispensing head 104 provided with a spray nozzle 105
  • the container 102 and the dispensing head 104 are capped by a cover 106 provided with a lever 107 fixed to the cover 106 by a film hinge 108.
  • the film hinge 108 is linear and is located in the vicinity of the connection point. between the peripheral skirt 111 of the cover fixed by snap-fastening on the container 102 and the upper surface of the cover.
  • the lever 107 is formed by a cut in the upper surface of the cover.
  • the lever 107 carries a support element 109, which is constituted by a cam whose lateral surfaces are parallel to the median plane of the lever and are slightly spaced from one another.
  • the bearing surface 109 a of the element 109 is cylindrical, of generatrices parallel to the articulation axis formed by the film hinge 108. In other words, the direction of the generatrices is perpendicular to the plane of FIG. 2.
  • the section of the surface 109 a by the median plane of the lever 107, orthogonal to the generatrices, is an involute of the circle C, centered on the film hinge 108 and tangent to the axis XX of the head 104.
  • the upper surface 104 a of the head 104 is planar, orthogonal to the axis XX and is limited by a circular contour centered on the said axis XX.
  • the head 104 is cylindrical of revolution.
  • the upper surface 104 is a pusher.
  • the involute 109a of the circle C is selected so as to be tangent to the center of the pusher 104, at a point P, on the axis XX when the assembly is at rest.
  • the axis of rotation of the lever 107 is located above the plane of the plunger 104, that is to say the side of said pusher 104 has opposite to the container 102.
  • Lateral guide means can be provided between the cam 109 and the head 104. It can be, for example, a groove or a shoulder (not shown), provided on the pusher 104 a , with which cooperates the cam 109 for holding in a direction perpendicular to the plane of FIG. 2.
  • the cover 106 is provided with an opening 110 arranged opposite the nozzle 105 so as to allow the jet of sprayed fluid product to pass.
  • FIG. 3 makes it possible to understand the operation of the assembly and the mode of action of the cam 109 in the involute of a circle.
  • the profile 109 a is the involute of the circle C, centered on the axis of articulation 108 and tangent to the axis XX of the pusher. At rest, the involute 109 a is tangent to the face 104 a , at its center P.
  • the friction between the parts is reduced and the sliding conditions of the head 104 are improved.
