Definitions

  • the present invention relates to a spraying process using a manual pump sprayer for improving the distribution of the sprayed product and a manual pump sprayer for carrying out the process.
  • the dosage of the sprayed product is easily obtained, in the case of a sprayer with a manual pump, by the number of pumps carried out by the user (that is to say by the number of actuation movements of the pump) .
  • the present invention therefore relates to a method of spraying a liquid product using a sprayer with a manual pump, the product to be sprayed being contained in a container, to which the fixed part of a manual pump is fixed.
  • dispenser the movable part of which is associated with a push button, said push button making it possible to move the movable part of the pump in translation relative to the fixed part to cause dispensing, said push button carrying a spray orifice which is supplied with spray product by a distribution channel connected to the movable part of the pump, characterized in that a rotation movement is communicated to the spray orifice around the axis of the pump between two extreme positions during each translation of the push button.
  • the two extreme positions are advantageously those occupied by the orifice at the two ends of the travel of the push button and of the mobile part of the pump.
  • the orifice is located, in these two extreme positions, in axial planes making between them a predetermined angle, possibly at different levels relative to the container.
  • the angle between the two axial planes passing through the axis of the pump and enclosing the spray orifice in the two extreme positions is between 10 and 50 °; it is preferably close to 20 °.
  • the quantity of product sprayed during a pumping operation is distributed over a larger area.
  • the angle of the spray cone of the product is 20 ° and the angle of rotation of 40 °
  • the covered area for spraying is at least four times greater than when there is no rotation of the spray orifice.
  • the average density of the sprayed droplets is therefore lower; we Therefore reduces the risks of formation of accumulation zones of the sprayed product and the drawbacks which result therefrom.
  • the rotation of the spray orifice is advantageously obtained by sliding at least one lug secured to the push button associated with the movable part of the pump, in at least one groove formed in an element connected to the fixed part of the pump. , the lug sliding in the groove during the translational movement of the push button.
  • the groove can also be replaced by a ramp on which a lug comes to bear.
  • the profile of the groove or the ramp determines the displacement of the spray orifice and its total angle of rotation.
  • the projection P of the groove on a plane Q perpendicular to the axial plane passing through the mean position of the dispensing orifice can be a rectilinear segment of length 1 making with the axis of the pump an acute angle ⁇ , preferably less than 45 °.
  • the projection P of the groove can also have a bent shape and in particular, be made up of two rectilinear segments, preferably equal, making an angle between them, preferably an obtuse angle.
  • the bent profile of the groove causes, for a single operation of the pump, a double sweep of the target surface by the sprayed product.
  • the groove can also have, in projection on the plane Q, a curved shape, in particular the shape of a flattened S. Indeed, it is known that, during a spraying operation of the pump, the curve giving the quantity of sprayed product as a function of time is not a straight line; during spraying, there is generally first a phase of acceleration of the flow, then finally a phase of deceleration.
  • the profile of the flattened S-groove has the advantage of correcting this drawback and of providing a more homogeneous distribution of the sprayed product.
  • the present invention also relates to a sprayer with a manual pump for implementing the method of the invention, in which the product to be sprayed is contained in a container to which the fixed part of a manual dispensing pump is attached, the mobile part is associated with a push button, said push button making it possible to move the mobile part of the pump in translation relative to the fixed part to cause dispensing, said push button carrying a spray orifice which is supplied with product to be sprayed through a distribution channel connected to the movable part of the pump, characterized in that the push-button cooperates with a fixed element secured to the container so that a translation of the push-button causes it to rotate around its axis.
  • the push button externally carries at least one lug constituting a radial projection which cooperates with a groove formed in the fixed element integral with the container.
  • the push-button has a groove on its side wall, the fixed element of the container carrying a lug which slides in said groove.
  • the push button comprises, in known manner, a substantially planar upper face, provided with a cylindrical skirt facing the container, the dispensing orifice being formed in a pellet carried by said skirt;
  • the fixed element is a coaxial cylindrical wall connected to the fixed part of the pump, the push button moving in translation opposite said cylindrical wall so that a lug carried by one slides in a groove in the other;
  • the cylindrical wall constituting the fixed element can extend 360 ° around the axis of the pump or be only constituted by one (or more) cylindrical sector (s).
  • the dispensing orifice may open at the level of the external wall of the cylindrical skirt of the push button or be at the end of a spout extending radially from this skirt.
  • the projection P of the groove on the plane Q previously defined can, of course, have the different shapes described above: linear, angled, curved or in the form of a flattened S.
  • the upper face of the push-button can be smooth or grooved and be used as it is, in particular when the angle of rotation of the spray orifice is small, for example of the order of 15 °. In this case, the user does not generally feel the rotation of the push button under the finger.
  • the upper face of the push button can also be covered with a movable part carried by the push button and fixed so as to be free to rotate relative to said push button.
  • This arrangement is particularly advantageous when the angle of rotation is greater than about 15 °; indeed, the rotary movement of the push button would then be sensitive under the user's finger.
  • the moving part which is interposed between the finger and the push button, remains fixed relative to the finger and the push button, during its translation, pivots relative to said part. The moving part prevents the user from feeling the rotation of the push button under his finger.
  • Figures 1 and 2 show in the rest position a vaporizer according to the invention designated as a whole by the reference 1. It comprises a pump, the movable part of which comprises a push button 2 fixed on a rod 3 movable in translation along the axis X - X of symmetry of the dispensing head and in rotation about this axis X - X.
  • the fixed part of the pump comprises a cylindrical-conical skirt 4 secured to the neck (not shown) of the container; the edge of the conical part of the smallest diameter is extended by a partial skirt 5, constituted by a cylinder sector.
  • the push button 2 is constituted by a planar circular upper face 21 on the edge of which is arranged a cylindrical skirt 22 facing the container.
  • the distribution channel (not shown) of the sprayed product opens out through the orifice 7 formed in a pellet carried by the skirt 22 in the vicinity of the upper face 21 of the push button 2.
  • the device operates as follows.
  • the user wishes to spray product, he presses the upper face 21 of the push button 2, gives it a translational movement along the axis X - X and actuates the pump; it thus causes the spraying of the product to be distributed through the orifice 7.
  • the lug 8 fixed on the skirt 22 slides in the groove 6 and causes the rotation of the push button 2 and of the rod 3 around the axis X - X until the lug 8 comes into abutment at the lower part of the groove 6.
  • Figures 3 and 4 show the dispensing head at the end of pumping and therefore spraying.
  • Figures 5 to 7 show different shapes of the groove in projection on a plane perpendicular to the axial plane passing through the average position of the dispensing orifice.
  • the groove 106 has a straight profile.
  • the groove 206 has a bent profile; it consists of two rectilinear segments 261 making between them an obtuse angle of approximately 110 °. A double scan of the target surface is thus obtained by the jet of substance sprayed during the same pumping action.
  • the groove 306 has the shape of a flattened S.
  • the groove 306 consists of three linear segments; two shorter parallel segments 361 are attached to each end of a longer central segment 362. The segments 361 make, with the segment 362, an obtuse angle of 100 to 110 °.
  • FIG. 8 shows the distribution of the droplets of sprayed product at each pumping action on a target surface determined when the groove 106, of rectilinear profile, is used. We see that the central area is lightly loaded and that the extreme areas are even less.
  • FIG. 9 shows the distribution of the droplets of sprayed product at each pumping action when the flattened S-shaped groove 306 is used. It can be seen that the density of the sprayed droplets is practically the same over the entire target surface. The distribution is therefore more homogeneous.
  • Figures 10 and 11 show a push button on the upper face of which is mounted a movable part in rotation relative to said face 421.
  • the upper face 421 of the push button 402 is covered by a movable part 409 carrying a cylindrical skirt 491 fixed so as to be movable in rotation, by snapping, using a bead 492 in a groove 423 of the cylindrical skirt 422 of the push button 402.
  • the skirt 422 carries two diametrically opposite lugs 408. These two pins cooperate with two identical grooves (not shown).
  • the moving part 409 When the user presses on the moving part 409 and gives the push button a translational movement 402, the moving part 409 remains stationary under the user's finger and the push button 402 is animated by a rotational movement. The user therefore does not feel the rotation of the push button under his finger.
  • the upper face 521 of the push-button 502 is covered with a movable part 509 which is fixed by an axial projection 591 in the shape of a bulb which cooperates with a corresponding axial cavity 523 formed in the upper part 521 of the push button 502.
  • the part 509 remains stationary under the finger of the user when he presses the push button 502, while the push button 502 is animated by a rotation movement.
  • FIG. 12 illustrates an embodiment of the hand pump sprayer according to the invention in which the user depresses the push button 602 using a lever 609.
  • This lever is articulated by at least one tab 691 on a support 610 secured to a cover 611 fixed to the container of the vaporizer and surrounding the push-button 602 as well as the skirt 605 comprising the groove cooperating with the lug (not shown).
  • the support 610 protrudes parallel to the axis, relative to the surface of the cover 611.
  • the lever 609 is provided, vis-à-vis the upper surface 621 of the push button, with a support element 692 having a shape such that the push button 602 can rotate without excessive friction relative to the lever 609 It is equipped at the end opposite the legs 691 with a surface forming a support 693 for the user's finger (s).
  • the user presses on the surface 693, the support element 692 presses on the upper face 621 of the push button 602 and presses said push button.
  • the push button 602 by the combined action of a lug and a groove (not shown), is driven in a rotational movement.
