Definitions

  • the present invention relates to a device for actuating a dispensing valve fitted to a container, containing a product to be dispensed, in particular a pressurized aerosol, the valve comprising a tubular push control rod.
  • FR-A-2 113 376 describes an actuating device for regulating the distribution of a material, from a pressurized container provided with an upper opening formed by a bowl for mounting a valve, the bowl being fixed to the container opening by a crimping bead or rolled seal.
  • This device comprises a lever in one piece provided at one end with a surface which can be engaged by an operator's finger and at the other end with a flexible clip which clips onto the bead. Between these two ends, the lever comprises a stud coming into abutment against the end of the tubular control rod of the valve.
  • the clip and the corresponding bead part constitute the fulcrum of the lever.
  • the lever pivots substantially around an axis orthogonal to the longitudinal axis defined by the tubular rod.
  • This construction has drawbacks.
  • the area of application of the force has a small angular extent and it is advisable to apply a finger to the area provided for this purpose which is of modest size.
  • the lever multiplier effect of the lever is limited by the very construction of the device, since the fulcrum of the lever is located approximately on the bead of the closure cup of the container while the other end preferably does not exceed the overall radial of the container for reasons of space and also to allow the establishment of a cover covering the entire device and coming to be fixed on the container.
  • the force to be exerted must be applied to an angularly reduced area and, moreover, it remains significant since the leverage is limited by the very construction of the device.
  • GB-A-1 359 152 describes a device in which the area of application of force by the user has an angular extent of 360 °, which allows the user to have a large bearing surface and choose without constraint the point where the actuation force will be exerted.
  • the push button is constituted by a conical surface comprising on its axis a stud, which presses on the valve stem, a cylindrical skirt being integral with said conical surface and being provided with support means capable of cooperating , either outside or inside, with a stop constituted by the crimping bead of the valve bowl.
  • a lever system is formed, the fulcrum of which is located on the crimping bead, this fulcrum being located substantially in a plane passing through the longitudinal axis and the point of application of the force.
  • the lever multiplying effect of the lever is determined by the construction of the container and, consequently, the force to be applied necessarily remains significant.
  • the present invention relates to a device in which the force to be applied by the user to depress the valve stem can be modularly reduced, without modifying the force of the valve spring.
  • the present invention consists of a device for actuating a dispensing valve fitted to a container containing a product to be dispensed, in particular a pressurized aerosol, the valve comprising a tubular control rod defining a longitudinal axis and having an end provided a dispensing orifice, the device comprising lever means for actuating the valve, these means comprising a push button, the external face of which comprises an application zone for an actuating force of the valve, the push button comprising, on the one hand, a stud abutting against the end of the rod and equipped with a dispensing nozzle and a channel connecting the dispensing orifice to said nozzle and, on the other hand, means of '' own support to cooperate with complementary abutment means linked to the container to form a fulcrum of the lever, in which said zone of application has an angular extent centered s ur said longitudinal axis of at least about 180 ° and, the support means and the abutment means have
  • the support points of the lever on the ring are preferably located closer to the valve than when said fulcrum is located on the crimping bead of the valve; therefore, the force required to operate the valve is lower.
  • the ring can be attached to any type of container: one-piece container or three-piece container.
  • the fulcrum of the lever is located on the crimping bead of the valve bowl, it is generally located at a level below the level of the top of the valve stem.
  • the ring according to the invention can easily be dimensioned so that the support points of the lever are located substantially in a plane perpendicular to the axis of the ring and passing through the end of the tubular rod.
  • said ring bears by a lower edge on the container and comprises a fixing means able to cooperate with a re-entrant part of the container included under said bead.
  • this push-button has the advantage of a large surface of use, facilitating the control.
  • said angular extent of the application area is between approximately 180 ° and 360 °, in particular, of the order of 270 °. This large area of use improves ergonomics. Indeed, it allows to put several fingers on the push button or a single finger if desired without any particular positioning effort: the placement of the finger is natural.
  • the angular extent of the support means and stop means is between approximately 180 ° and 360 ° to be in correspondence with the preferred values of the angular extent of the application area.
  • the support points formed by the support means and the complementary abutment means have, as a geometrical place, a narrow strip in an arc of a circle or circle whose angular opening is between approximately 180 ° and 360 °, and whose axis coincides with said longitudinal axis.
  • This arrangement is preferred because the distance between any fulcrum and the end of the control rod is substantially constant, which has the effect of making the actuating force to be applied to the push button substantially constant when the point d application of this actuating force remains substantially at the same distance from the longitudinal axis.
  • the lengths of the lever arms used then have practically constant values. Under these conditions, the effort to be exerted, for example by a finger, will essentially depend on the distance from its area of application to the longitudinal axis but will be independent of the angular position of the area. application on the push button.
  • the support means surrounding said stop pin comprise a cylindrical sleeve, of revolution about the longitudinal axis, having, in the vicinity of its open end towards the container, a projecting radial shoulder generally forming a circular ring whose outer contour forms a support circle capable of cooperating with the complementary stop means.
  • the complementary stop means located on the ring are constituted by a flat face substantially orthogonal to the longitudinal axis and fixed in position opposite the container, this face being delimited by a circular opening coaxial with the longitudinal axis and d 'a radius greater than the outside radius of the sleeve but less than the radius of the support circle.
  • This arrangement has the advantage of retaining the push button because the circular ring of the socket bears against the flat face in a zone close to the circular opening.
  • the above means together determine in a very simple manner a single fulcrum when the plane of the ring is slightly inclined relative to the planar face while remaining in contact with it.
  • the circular ring is divided into several segments by interstices in order to make them slightly deformable and to facilitate, during assembly, the crossing of the coaxial circular opening by said ring.
  • the circular ring is continued by a frustoconical side face converging towards the open end of the sleeve to also facilitate the positioning and the crossing by the ring of the circular opening. coaxial.
  • the ring is in contact with said face or in the immediate vicinity thereof when the tubular stem of the valve is at rest. This arrangement allows an immediate attack of the valve by an actuating force by reducing the play of the mechanism.
  • the channel opens into a frustoconical recess of the stud, this recess overlapping the end of the rod in abutment in a connection link.
  • the dispensing nozzle is formed substantially in the center of the external face of the push button and in a substantially longitudinal direction. This arrangement makes it possible to confer an angular extent of 360 ° for the area of application of the actuating force.
  • the dispensing nozzle is formed on the stud in a substantially radial direction.
  • Figures 1 to 4 show a first embodiment of the present invention in which there is a container, known per se, generally designated by the reference sign 1 and containing a pressurized aerosol.
  • This container is of the type with upper opening closed by a circular bowl 2 for mounting a distribution valve from which there is a tubular control rod 3 defining a longitudinal axis X-X.

  • the wall 18 of the push-button 10 and a part of the socket 30 are interrupted by two radial edges which define an angular sector greater than or equal to the angular sector of the jet exiting in operation from the nozzle 21
  • the radial edges of the wall 18 continue downwards by two flat walls 51 and 52 which join the stud 20 and which end in a wall 53 in a circular sector substantially orthogonal to the axis XX and in one piece with the nipple 20 in an area close to its lower end.
  • the generally circular lower end of the sleeve 30 continues in one piece with the wall 53 under the underside of the latter.
