Definitions

  • the invention relates to a dispenser of a product in liquid form with a more or less viscous consistency.
  • This dispenser can be used in different areas of use and serve for the distribution of cosmetic products (hairspray, deodorant, hair foam, body milk, depilatory foam, liquid foundation, sunscreen milk) or dermopharmaceuticals (insect repellant, analgesic or anti-inflammatory), household products, paint, etc. as a liquid, spray or foam.
  • the dispenser of the invention comprises, in a known manner, a container provided with a dispensing valve and which contains the product to be sprayed, the valve being equipped with a control rod; a push button comprising a pin capable of acting on the rod; a conduit passing through the pin and connecting one end of the rod to a nozzle provided in the push button; a retaining band, capable of being fixed on the container and provided for the maintenance of the push button.
  • a dispenser of this kind has been described by the applicant in document FR-A-2 661 661.
  • This dispenser makes it possible to actuate the dispensing valve by exerting a reduced force on the push button, which gives the user a feeling of smooth operation when actuated.
  • the force application area has a relatively large angular extent, which facilitates the use of this distributor.
  • the actuating device (hoop - push button) of this dispenser consists of two separate parts, which requires assembly, on a production line, relatively expensive and complex, from an industrial point of view.
  • Another drawback lies in the fact that the valve which can be used for this prior distributor is limited to the use of a valve known as with lateral deformation, which requires a specific industrial mounting tool. This results in a high cost price for the distributor.
  • the present invention therefore aims to simplify the manufacture and assembly of such a dispenser.
  • the present invention aims, above all, to provide a dispenser of the kind defined above whose manufacture and assembly are simpler than those of the device according to FR-A-2 661 661, and whose cost is as low as possible .
  • a dispenser according to the preamble of claim 1 is known from application FR-A-2697812.
  • valve which can be used to equip the dispenser according to the invention is advantageously a conventional recess valve.
  • a valve with lateral deformation called a "tilt" valve, can also be used.
  • the ball joint connecting the push button to the hoop has, preferably, the shape of a diabolo whose zone of smaller section allows a determined rotation around the longitudinal axis of this section as well as a slight pivoting of the button. pusher in a direction perpendicular to this axis and having as its center of rotation the zone of smallest cross section of this ball joint, so that a depression of the push button relative to the hoop in the direction of the bottom of the tank cannot have place by pressing an area on the upper surface of the push button located to the right of the dispensing nozzle.
  • the dispenser has several legs, movable in translation.
  • these are advantageously 2, 4, 6 or 8, arranged symmetrically between the hoop and the push button.
  • the lug (s) are movable in translation, unidirectionally, in the direction of the axis of the tank towards the bottom of the tank.
  • each tab is secured to the hoop (or of the push button), each first end being situated in a plane, perpendicular to the axis of the reservoir and containing the axis of the ball joint; each second end of the tab is therefore integral with the push button (or the hoop).
  • the attachment points of the first and second ends of each tab are located at a different level.
  • the tab or tabs are arranged in the annular space formed between the push button and the hoop in the plane perpendicular to the axis of the reservoir and containing the axis of the ball joint.
  • each tab has a non-constant section between its two ends.
  • zones of smaller section constitute folding and unwinding zones when the push button is pressed.
  • the invention also relates to a push button, intended to equip a dispenser provided with a dispensing valve, as defined above, this push button forming a single piece with its retaining band, the push button being connected to the hoop with a ball joint and at least one tab allowing sufficient travel of the push button to control the opening of the valve.
  • Figure 1 is a partial axial section of a dispenser according to the invention.
  • Figure 2 is an enlarged top view of the device of Figure 1, according to a first embodiment of the invention.
  • FIG. 3 represents an axial section along line III-III of FIG. 2.
  • FIG. 4 represents a section along line IV-IV of FIG. 2.
  • Figure 5 is an enlarged view of the magnifying glass A of Figure 2, showing a side view of the patella.
  • Figure 6 is an enlarged view of the magnifying glass B of Figure 2, showing a side view of the tab.
  • Figure 7 is a top view of a dispenser according to a second alternative embodiment of the invention.
  • a spraying device designated as a whole by the reference 1, comprising a dispensing valve 2 fitted to a reservoir 3, generally cylindrical, under pressure using a gas propellant, and having an X axis of symmetry.
  • the reservoir 3 contains, for example, a cosmetic or dermo-pharmaceutical liquid product, to be distributed in the form of an aerosol. It is also possible to use a reservoir equipped with a pocket or a piston on which a propellant acts indirectly, for the distribution of a cream or other product of more or less viscous consistency.
  • the device 1 comprises a push button 4, in the form of a cap, having a peripheral edge 4c, which comprises, along the axis of its concavity, and therefore of the axis X, a cylindrical pin 5 secured to the upper wall 4a of the push button 4.
  • the pin 5 is traversed by an axial duct 6, which is connected, to a transverse channel 7 leading to a nozzle 8 mounted, conventionally on a centering piece provided in the push button in an area depression 4b.
  • the free end of the conduit 6 has a larger diameter bore than the conduit 7, so as to form a housing 10, capable of receiving, with a slight tightening, the free end of a control rod 11 of the valve 2.
  • This valve is of the conventional "push-in” type, the opening of which is controlled by pushing in the rod 11 in the direction of the axis X towards the bottom of the tank.
  • the valve 2 comprises a body 12 which is crimped in the upper part, from the side of the control rod, in a cup 13, fixed by crimping or by swaging on the rolled edge 14 of a circular opening at the upper end of the reservoir 3.
  • the body 12 On the lower part of the valve, on the side opposite to the control rod, the body 12 can be provided with a connection zone 15 of reduced diameter, extended by a dip tube 16 extending to the bottom of the reservoir 3.
  • the place where the user exerts this pressure is not critical: the device operates by pressing anywhere on the bearing surface 4d.
  • the push button 4 with its peripheral edge 4c is connected to a first annular edge 23a of a fixing hoop 23, of generally cylindrical shape, by a ball joint 30 which has approximately the shape of a diabolo, and by one or more tabs 40 authorizing a determined mobility of the push button 4 in the axial direction of the reservoir, relative to the hoop 23, sufficient to control the opening of the valve 4.
  • the diabolo shape is not compulsory: as a variant, the ball joint 30 can be achieved by a simple bridging piece whose length / diameter ratio is, for example, between 1 and 3.
  • the push button 4, the hoop 23, the ball joint 30 and the tabs 40 form a single piece which can be made, for example, of polypropylene.
  • the second annular edge 23b of the hoop 23 internally comprises a snap-fitting bead 24, capable of snapping into an annular groove 3c provided in the junction zone between the cylindrical part 3b of the reservoir 3 and the dome 3a covering this reservoir and ending with the rolled edge 14.
  • the ball 30 comprises two attachment elements 31, 32 of conical shape, one of which 31 is integral with the inner wall of the edge 23a of the hoop 23 and the second of which 32 is integral with the peripheral edge 4c of the push button; the two elements 31, 32 are connected by the tip of the two cones in an area 33 of smaller section constituting a bending and / or pivoting area.
  • the ball 30 is located on a plane P (plane of FIG. 3) passing through the center of the nozzle 8 and the axis X of the reservoir 3.
  • This arrangement of the ball joint 30 does not allow vertical movement of the push button 4, that is to say a depression, but constitutes a fixed and effective fulcrum for the latter, while allowing a slight rotation of the button- pusher around its longitudinal axis X by torsion, when it is actuated by pressing on the support zone 4d. At the same time, this arrangement allows a slight rotation along the longitudinal axis Z of the diabolo, having as its center of rotation the center of the diabolo itself.
  • the ball 30 is located under and in front of the depression zone 4b, and in a centered manner with respect to this depression.
  • Figure 6 shows a side view of a tab 40 in the rest position.
  • the legs 40 are arranged symmetrically with respect to the plane P passing through the axis X, the center of the nozzle 8 and the ball joint 30, between the edge 4c of the push button and the inner edge 23b of the hoop 23.
  • a single leg 40 can be provided on the plane P on the side opposite to the ball joint 30.
  • the legs 40 connecting the push button to the hoop 23 are regularly distributed in an angular zone of approximately 40 ° to 140 °, as shown in FIG. 2.
  • Each tab 40 is a strap 43 of decreasing thickness from its point of attachment 41 to the edge 23a of the hoop 23, at the point of attachment 42 to the edge 4c of the push button.
  • the strap 43 has an angular orientation relative to the X axis, so that the attachment points 41 and 42 are at two different levels.
  • the attachment point 42 is located in the plane R (plane of FIGS. 2 and 5) perpendicular to the axis X and containing the axis Z, and the attachment point 41 is at a lower level relative to to this plan R. This provision prohibits an elevation of the push button.
  • the junction zones of the strap 43 at the attachment points 41 and 42 respectively constitute flexion zones which facilitate the folding of each tab 40, when the user exerts pressure on the support zone 4d, thus authorizing the lowering of the push button 4.
  • the width of the legs 40 can be modulated as a function of their number and position relative to the ball joint 30. As the fulcrum on the zone 4d moves away from the nozzle, the more the feeling of smooth operation of the distributor increases.
  • the legs 40 and the ball joint 30 are located in the annular space defined between the hoop 23 and the push button 4.
  • the dispenser 1 can be capped by a protective cover (not shown) fitting on the edge 23a of the hoop 23, which the user removes before use.
  • the user presses any zone on the surface 4d of the push-button (in the direction of the arrow F in FIGS. 3 and 4) causing it to tilt around the ball joint 30
  • the legs 40 as a function of their distance from the ball joint, will undergo a movement in the direction of the valve, and cause the opening of the latter; the liquid, under the thrust of the propellant, will then go up, via the dip tube 16, into the body 12 of the valve, from where it will be conveyed, through the rod 11, the conduit 6 and the channel 7, towards the spray nozzle 8.
  • the purpose of the depression 4b practiced at the right of the nozzle 8 of the push button is to prevent the spray cone leaving the nozzle 8 from dirtying the push button. Furthermore, if the user inadvertently presses on this vacuum zone 4b, thanks to the presence of the ball joint 30 in the vicinity of this zone 4b, the spraying cannot be triggered.
  • Figure 7 is a view similar to that of Figure 2 and is an alternative embodiment. Compared to Figure 2, the references of identical parts or playing a similar role have been increased by 100 and their description will not be repeated. Thus, the push button 104, the hoop 123 and the ball joint 130 have a structure identical to the corresponding parts of FIG. 2. Only the lugs 40 of FIG. 2 have been replaced by lugs 140 of different shape, arranged in the annular space between the lower edge 104c of the push button 104 and the upper edge 123a of the hoop 123.
  • Each tab 140 has a first end 141 which forms a point of attachment to the edge 104c of the push button and a second end 142 forming a point of attachment to the edge 123a of the hoop 123.
  • the ends 141 and 142 respectively of two tabs 140 consecutive are arranged in the vicinal position.
  • the legs 140 are arranged in the plane R perpendicular to the axis X of the reservoir and which contains the axis Z passing through the ball joint 130.
  • each lug 140 can be arranged so that one end 141 of a first lug 140 is opposite the end 142 of a 140 consecutive paw.
  • the user will appreciate the smooth operating comfort of the dispenser according to the invention.
  • it will exert a lower supporting force than that necessary for the distribution of a conditioned liquid in a conventional dispenser of this kind.
  • the solution of the invention consisting of a push button and a mounting hoop formed in a single piece, allows savings not only from the mounting point of view, but also during manufacture, since only one mold is necessary. .
