Definitions

  • the invention relates to a device for actuating a dispensing valve fitted to a container containing a liquid product to be dispensed, in particular cosmetic (lacquer) or pharmaceutical, the valve comprising a tubular control rod.
  • the device is of the type which includes a push button in the form of a cap and comprising a pin capable of acting on the rod, a conduit passing through the pin and connecting the outlet of the tubular rod to a nozzle provided in the push button.
  • a retaining ring suitable for being fixed on the container, being furthermore provided for the maintenance of the push button, the push button comprising an area of application of a force on the push button to actuate the valve d '' an angular extent of at least 180 °.
  • a device for dispensing a product as described in the preamble of Claim 1 and equipped with a device for actuating a dispensing valve is known, for example from FR-A-2 661 661.
  • the push-button comprises support means capable of cooperating, in order to actuate the valve, with stop means of a retaining ring fixed on the container.
  • the push button comprises a cylindrical sleeve extending in the concave part of the internal face of the push button and having a radial shoulder in the form of a circular ring capable of cooperating with the stop means of the ring.
  • the installation of the fixing ring - push button distributor assembly may inadvertently trigger the valve and therefore release a quantity of product. This untimely actuation of the valve during assembly is due to a lack of flexibility of the device.
  • FR-A-2 627 157 a safety control device in which it is necessary to deform a part of the retaining ring of the push button so that it can be actuated.
  • a stop lug in contact with the valve cup makes it possible to limit the deformation of the ring.
  • the object of the present invention is precisely a device for actuating a dispensing valve fitted to a container containing a product to be dispensed, making it possible in particular to remedy these drawbacks.
  • This device has, in particular, good flexibility avoiding actuation of the valve during its mounting on the container and also makes it possible to control the flow of the aerosol during use.
  • the invention therefore relates to a sensitive device for dispensing a product as defined in claim 1.
  • the Applicant has found, surprisingly, that by directly connecting the push button to the retaining ring by a flexible thin wall distributed evenly over the periphery of the push button, a device is obtained having good flexibility of actuation over the entire area of application of the actuating force of the valve.
  • This flexibility is due to the cooperation of a crushing movement of the flexible thin wall at the point of pressing on the push button and of a stretching movement of the flexible thin wall at the diametrically opposite place. where the push button is pressed. Thanks to this tilting, a sensitive push button is obtained.
  • the invention makes it possible to facilitate the manufacture and assembly of such a device.
  • the fabric has a U-shaped cross section, the concavity of which is turned towards the side opposite the container.
  • the fabric in cross section has the shape of a straight line.
  • the fabric can be continuous and extend along the entire periphery of the push button.
  • the fabric may be discontinuous and be formed by several segments distributed regularly over the periphery of the push button.
  • an abutment tab is provided under the push button, substantially in the same radial direction as the nozzle, to cooperate with an abutment zone linked to the container.
  • the abutment zone linked to the container may consist of an edge zone set with a cup used for fixing the valve.
  • the device comprises a "tilt" valve, the opening of which is controlled by the tilting of the rod relative to the axis of the valve.
  • a tilt valve reacts to a slight lateral stress, which gives the control a great feeling of softness.
  • valve the opening of which is controlled by a substantially axial depression of the control rod.
  • the push button can be arranged to ensure lateral mounting of the nozzle with a product outlet orifice having an axis oriented transversely to the axis of the valve control rod.
  • the push-button can be arranged for mounting the nozzle in the axis of the control rod, with product outlet oriented along said axis.
  • the invention also relates to a sensitive push button as defined in claim 12.
  • a stop tab can be provided under the push button, substantially in the same radial direction as a nozzle.
  • Figure 1 of these drawings is an axial vertical section in the closed position of a device, according to a first variant, for actuating a dispensing valve, according to the invention, shown mounted on the upper end of an aerosol can.
  • Figure 2 shows, similarly to Figure 1, the device in the valve actuation position.
  • Figure 3 shows, similarly to Figure 1, an alternative embodiment with axial product outlet.
  • Figure 4 shows, similarly to Figure 1, another alternative embodiment with axial product outlet.
  • Figure 5 finally, similarly shows in Figure 1, another alternative embodiment with axial product outlet.
  • the device 1 comprises a push button 4, in the form of a cap, which comprises, along the axis of its concavity, a cylindrical pin 5 secured to the upper wall of the push button 4.
  • the pin 5 is crossed by a conduit 6 axial, which is connected, in the upper part, to a transverse channel 7 leading to a nozzle 8 conventionally mounted on a centering piece 9 (generally known under the name "center post") provided in the push button 1, right angle of the axis of the duct 6.
  • the lower part of the conduit 6 has a larger diameter so as to form a housing 10 suitable for receiving with slight tightening the upper end of a control rod 11 of the valve 2.
  • the valve 2 is of the “tilt” valve type, the opening of which is controlled by a tilting of the rod 11 relative to the axis A of the valve.
  • the valve 2 comprises a body 12 open at its two longitudinal ends and bordered, in the upper part, with a collar crimped in a cup 13 also fixed by crimping on the rolled edge 14 with a circular opening provided at the upper end of the container 3.
  • the valve body 12 is provided, in the upper part, with a sealing washer 15 crossed by the rod 11.
  • the washer 15 establishes a seal between the wall of the cup 13 and the valve body 12.
  • the rod 11 comprises , at its lower end, a sort of hollow plate 16, the periphery of which is provided with a rib 17 capable of being applied in a sealed manner against the washer 15, under the action of a spring R placed in the body 12.
  • the internal volume of the hollow plate 16 communicates with the interior of the rod 11 through an orifice 18.
  • at least one orifice 19 is provided in the upper wall of the plate 16, radially outside the rod 11 but at inside the rib 17.
  • the rib 17 moves away from the washer 15, according to a certain angular extent, which makes it possible to establish communication between the interior of the valve body and the interior r of the rod 11 through the orifices 19 and 18.
  • the valve is then opened as illustrated in FIG. 2.
  • the push button 4 has, below its wall, a stop tab 20 located substantially in the same radial direction as the nozzle 8 and suitable for coming to bear against a complementary stop means linked to the container 3 and constituted by a zone 21 of the fixing edge of the cup 13.
  • the upper wall of the push-button 4 has a support zone 22 situated substantially opposite to the radial direction of the stop 20.
  • the push button 4 forms a single piece with a retaining ring 23 in the form of a cylindrical skirt, the lower part of which comprises, towards the inside, a bead 24 capable of snapping into a peripheral groove of the container 3.
  • the push-button 4 is connected to the ring 23 by a flexible flexible wall called a canvas 25, allowing movements of the push-button 4, relative to the ring 23, sufficient to control the opening of the valve 2.
  • the fabric 25, as visible in FIGS. 1 and 2, has a U-shaped cross section whose concavity is turned on the side opposite to the container 3.
  • the fabric 25 can be continuous and extend along the entire periphery of the push button 4
  • the fabric 25 is discontinuous and is formed by several segments distributed regularly over the periphery of the push button 4.
  • the skirt 23 has, at its upper end, a fastening ring 26 of diameter slightly smaller than that of the skirt.
  • a cover 27 can snap onto the rod 26.
  • the cylindrical wall of the cover 27 is advantageously in the extension of the cylindrical wall of the skirt 23.
  • the nozzle 8 is firstly mounted on the push button 4.
  • the cover 27 is then snapped onto the bead 26.
  • This sub-assembly is then slammed onto the can 3 by engagement of the bead 24 of the skirt 23 in the groove from the can.
  • the user removes the cover 27 and presses the push button 4 in the zone 22.
  • the button 4 is pushed towards the side of this zone 22.
  • the fabric 25 is crushed at the location of support while the tab 20 is pressing against the zone 21.
  • the flexible fabric 25 is crushed while at the place diametrically opposite to the place of support on the push-button, relative to the valve stem, the flexible fabric 25 stretches. In this case, it is the fabric 25 which, when deformed, serves as a pivot axis for tilting the push button.
  • the pin 5 rocks slightly relative to the axis A of the valve 2 and drives, in this tilting, the rod 11. This causes the valve to open and the product to exit, for example in aerosol form, through nozzle 8.
  • the lever arm corresponding to the radial distance between the support area 21 of the lug 20 and the support area 22 for the user, is important and allows particularly gentle control.
  • Valve 2 of the "tilt" type reacts to a lateral and small-scale stress to ensure opening. A displacement of 0.2 mm from the lower end of the pin 5 is sufficient.
  • the actuating device could be used with a valve for pushing in the rod 11 in the direction of the axis A of the valve body. In this case, it is necessary to cause a displacement of the pin 5, along the axis A, a little more significant, for example by at least 0.6 mm. With such an axial opening valve, the fabric 25 when deformed serves as a pivot axis.
  • the push button 104 is connected by the canvas 25 to the retaining ring 23.
  • the nozzle 8 is arranged in the center of the upper wall of the button 104, along the axis A.
  • the fabric 125 has in cross section the shape of a straight line. It consists of a continuous or discontinuous crown (or ring) of flexible plastic, for example of the elastomer type, which deforms when the zone 22 of the push button is pressed. It connects the skirt 23 of the ring to the push button 104.
  • the flexible plastic crown is produced by biinjection.
  • the plastic crown 125 has a thickness measured along the axis A of the valve, less than the width of said crown, measured in the plane of the figure.
  • the plastic crown 125 has a thickness measured along the axis A of the valve, greater than the width of said crown, measured in the plane of the figure.
  • the solution of the invention consisting of a single piece formed by the push button and the mounting skirt, allows savings not only from the point of view of assembly, but also in terms of manufacturing since only one mold enough.
  • This actuating device is suitable, in particular, for devices for spraying liquid or foam.
