Definitions

  • the present invention relates to a fluid dispenser head according to the preamble of claim 1, intended to be associated with or mounted on a fluid reservoir.
  • dispenser head here means the complete assembly intended to be mounted on a reservoir to constitute a fluid dispenser. By actuation of this head, fluid is removed from the reservoir and dispensed through a dispensing orifice.
  • Such dispensing heads are frequently used in the fields of perfumery, cosmetics or even pharmacy.
  • the dispensing head comprises a fluid dispenser member, such as a pump or a valve.
  • the dispensing member generally comprises a body fixedly mounted relative to the reservoir and a valve stem movable axially back and forth relative to the body.
  • the dispensing head also comprises an axially displaceable pusher reciprocating by driving the valve stem.
  • the dispensing head also comprises a dispensing orifice connected to the valve stem.
  • the only possible movement of the pusher is a reciprocating axial displacement printed by the user who presses with the aid of one or more finger (s) on a thrust surface. formed by the pusher.
  • the pusher being directly coupled to the valve stem, its displacement directly causes the displacement of the valve stem. In other words, the pusher and the valve stem move together at the same time.
  • dispensing heads are already known which are provided with pushers displaceable in rotation with respect to their axis of displacement in order to perform a function of locking the pusher.
  • the pusher can be rotated between a locked position in which it can not be moved axially and an unlocked actuating position, in which the user can press the pusher and move it axially back and forth to dispense fluid.
  • the pusher still remains coupled directly to the valve stem so that they are forced to move axially together at the same time.
  • distributors comprising a case in which are housed the dispensing head and the reservoir.
  • the case is provided with actuating means for moving the dispensing head and the reservoir inside the case to push the pusher out of the case for its actuation.
  • the pusher is directly connected or coupled to the valve stem and thus moves together at the same time.
  • WO 01/53157 discloses a dispensing head having the features of the preamble of claim 1.
  • the present invention aims to define another type of dispensing head in which the pusher is temporarily or selectively decoupled from the valve stem.
  • the present invention provides a fluid dispenser head according to claim 1.
  • the dispensing head comprises means camming device to transform the rotation of the pusher into an axial displacement of the pusher with respect to the valve stem.
  • the actuating means rotate without axial displacement relative to the body, the cam means being provided between the pusher and a fixedly mounted member relative to the body.
  • the pusher performs a combined movement in rotation and in axial translation with respect to the valve stem.
  • This combined movement is of the helical type.
  • the user acts on the actuating means by rotating them on themselves without axial displacement, which has the effect of driving the pusher both in rotation and in axial translation.
  • the dispensing head comprises fixing means for fixing the dispensing member on the reservoir, these fixing means comprising a ring engaged with both the dispensing member and the reservoir, and a locking ring for locking the ring on the tank, the actuating means being rotatably mounted on the hoop, the cam means being formed between the pusher and the hoop.
  • the pusher is housed inside the actuating means, the pusher and the actuating means having a section of polygonal shape, preferably square. Thanks to the polygonal shape, the pusher is directly driven by the actuating means without the need to provide a particular arrangement, as would be the case with a pusher and circular cylindrical actuating means. However, this latter circular cylindrical shape is not excluded in the context of the present invention.
  • the dispensing orifice is mounted on the pusher and is connected to the valve stem by a flexible conduit.
  • This flexible conduit allows the pusher to move both in rotation and in translation relative to the valve stem. Therefore, this flexible duct is deformed only during the displacement of the pusher relative to the actuating rod, but remains static on the contrary during the fluid dispensing phase, since the pusher is then directly coupled to the valve stem.
  • the dispensing orifice is masked by the actuating means in the low axial position.
  • the actuating means can thus serve as protective sheath for the pusher in the low axial position.
  • the valve stem is provided with a force transmitting member, the pusher engaging with said member in the high axial position and being disengaged from this member in the low axial position.
  • the pusher comprises two thrust flanges which are positioned on the member in the upper axial position on either side of the valve stem. Therefore, the pusher is completely decoupled from the valve stem in the low axial position. Actuation of the pusher in this low axial position would have no effect, since the pusher does not drive the valve stem. Conversely, in the high axial position, the pusher is coupled to the valve stem via the force transmission member.
  • the member is guided axially by the hoop. This implies that the force transmission member is not rotated by the pusher, but remains perfectly fixed in rotation, since the hoop is fixed relative to the body and the reservoir.
  • the pusher is axially displaceable by driving the valve stem only in the high axial position. In the low axial position, the pusher is decoupled from the valve stem. After each distribution of fluid product, the user can act on the actuating means to return the pusher in the low axial position, which can thus define a rest position, transport or storage.
  • One principle of the invention lies in the fact that the pusher is axially movable independently of the valve stem during a handling phase which is not the fluid dispensing phase. This manipulation phase is before or after the distribution phase.
  • This translational displacement of the pusher here is advantageously combined with a simultaneous rotation of the pusher which is advantageously allowed by the use a flexible conduit connecting the valve stem to the dispensing orifice formed on the pusher.
  • the dispensing head is intended to be associated with a fluid reservoir 1 which defines a body 10 and a neck 11.
  • the body 10 delimits a useful volume which is that of the tank.
  • the neck 11 defines an opening 12 which communicates the interior of the body 10 with the outside.
  • the neck 11 forms a protruding outer peripheral rim which defines a shoulder 13 facing downwards. This shoulder 13 will serve to hook the dispensing head on the reservoir.
  • the reservoir defines a polygonal section, advantageously square, at the level of the body 10.
  • the dispensing head in this particular embodiment, comprises six distinct constituent elements, namely a dispensing member 2, a hoop 3, actuating means 4, a pusher core 5, a fluidic connection system and thrust transmission 6 and a pusher cap 7. All these constituent elements can be made by injection / molding of suitable plastic material. Certain constituent elements may also be made of metal, such as, for example, the actuating means 4 and the push cap 7.
  • the dispensing member 2 may be a pump or a valve comprising a body 20 defining a low inlet optionally provided with a dip tube.
  • the pump or valve also includes a valve stem 21 which is axially displaceable back and forth within the body 20.
  • the valve stem 21 defines an internal fluid delivery pipe which is selective communication via an outlet valve with the interior of the body 20.
  • the pump or valve may also be equipped with a fixing ring 22 provided with attachment tabs 23 intended to engage below the shoulder 13 of the neck 12.
  • the fixing ring 22 is here presented as a constituent element of the dispensing member. However, the fixing ring may also be in the form of a separate element of the dispensing member which is attached to the dispensing member.
  • the fixing ring is an integral part of the dispenser member. This is a quite classic design for a pump or a valve in the fields of perfumery, cosmetics or even pharmacy.
  • the outlet valve By pressing on the valve stem 21, the outlet valve (not shown) is open and the fluid stored in the body 20 can flow out through the rod 21.
  • the fret 3 performs several functions. Its first function is to block or lock the fixing ring 22 on the neck 11 of the tank.
  • the band 3 defines a locking sleeve 32 whose inner wall comes into tight contact around the ring 22, as can be seen on the Figures 4, 5 and 8, 9 .
  • the hoop 3 thus prevents the lugs 23 of the ring 22 from disengaging from below the shoulder 13.
  • the locking bushing 32 also fulfills other functions.
  • the sleeve 32 is slotted so as to define two substantially semi-cylindrical parts separated by two axial slots 34.
  • the slots 34 do not extend over the entire height of the locking sleeve 32.
  • the locking sleeve 32 externally defines cam means in the form of two cam paths 33 which form grooves in the outer wall of the sleeve 32.
  • Each cam path 33 comprises a helical portion 331 and a vertical axial portion 332.
  • the axial portion 332 connects the helical portion 331 at its highest level.
  • Each cam path 33 extends substantially 90 °.
  • the helical portion 331 extends substantially 90 °, while the vertical axial portion 332 has substantially no angular extent.
  • cam paths 33 are intended to cooperate with two cam lugs formed by another constituent element of the head which will be described below. It is easily understood that the displacement of the lugs in the helical portions 331 will have the effect of axially displacing the constituent element to be described. This axial displacement will of course be combined with a rotational movement because the helical portion 331 extends about 90 °. In contrast, at the vertical axial portion 332, the cam lug can move axially vertically without rotating component.
  • the band 3 further defines a base 31 which is intended to come around the thickened base of the neck 11. The outer wall of this base 31 forms two elongate grooves 311 which extend substantially 90 °. Each groove is intended to cooperate with a lug which is free to move within its respective groove.
  • the actuating means 4 which will cooperate with the base 31 of the hoop 3.
  • the actuating means 4 define an inner cylindrical ring 43 which surrounds the base 31 of the hoop 3.
  • cylindrical crown is not visible on the figure 1 but we can see it on Figures 4 and 5 .
  • the ring 43 defines on its inner wall two rotational lugs 431 which engage in the rotation grooves 311 formed by the base 31 of the hoop 3, as can be seen in FIG. figure 5 .
  • the lugs 431 can thus move in their respective grooves 311 by rotation of the ring 43 around the base 31.
  • the rotary displacement of the ring relative to the base is limited by the abutment of the lugs 431 against the ends of the grooves 311.
  • the rotary displacement of the ring relative to the base can for example be limited to 90 °. Due to the perfectly horizontal orientation of the grooves 311, the ring 43 moves in rotation about the base 31 without axial or vertical component.
  • the actuating means 4 define an outer shroud 40 which is here of polygonal cross section, preferably square.
  • the fairing 40 is integrally connected to the ring by an annular flange 41, so that the fairing surrounds the ring.
  • the dimensions of the fairing are substantially identical to the dimensions of the body 10 of the tank so that the fairing 40 can be placed in the continuity of the body 10 of the tank, as can be seen on the figures 2 and 6 .
  • the lower edge of the fairing 40 is located near or in contact with the reservoir.
  • the fairing 40 constitutes gripping means for actuating the inner cylindrical ring 43.
  • the figures 2 and 6 represent the dispensing head with the shroud 40 in its two extreme positions of rotation aligned with the tank.
  • the fairing 40 is here of square cylindrical shape: it could however achieve the fairing 40 with another shape, such as hexagonal, octagonal, or even cylindrical.
  • the shape of the fairing 40 can be determined by the shape of the body 10 of the tank. However, it will be seen that it is advantageous to make the shroud 40 with a polygonal shape rather than with a circular cylindrical shape.
  • the pusher core 5 comprises an outer casing 51 of generally polygonal shape, advantageously square with the rounded corners.
  • the core 5 defines a central opening 52 which extends through the core.
  • This central opening 52 is defined by an internal sleeve 53 which is intended to engage around the sleeve 32 of the band 3.
  • This sleeve 53 defines on its inner wall two cam lugs 531 which are housed in the two paths of cam 33 formed by the sleeve 32 of the hoop 3.
  • the core 5 is movable relative to the hoop 3 by moving these two cam lugs 531 in the two sinuous cam paths 33.
  • the core 5 performs a combined helical displacement in rotation and in translation, while at the vertical axial section 332, the core 5 moves only axially without rotation component. Engagement of the core 5 on the bushing 32 is facilitated by the presence of the guide slots 34 which impart a certain elastic deformation characteristic to the bushing 32.
  • the inner sleeve 53 also defines a force transmission flange 56 which is more visible on the figure 7 . Its function will be given below with reference to the constituent element with which it interacts.
  • the core 5 also defines a housing 55 for receiving a nozzle which forms the dispensing orifice, as will be seen below.
  • the core 5 is at least partially engaged within the fairing 40 of the actuating means 4. Due to its cooperation with the cam paths 33 of the band 3, the core 5 is movable axially inside the fairing 40 so as to protrude upwards beyond the fairing.
  • the pusher core 5 is shown in the abutment axial low position and the abutment axial high position, respectively. It can be seen that the core 5 has moved axially with respect to the hoop 3 and to the tank 1 while following the cam paths 33.
  • the core has been shown static, and it is the fret 3 and the tank 1 which have been turned a quarter of a turn.
  • the actuating means have been omitted here for reasons of clarity in order to be able to observe the displacement of the core 5 with respect to the hoop 3.
  • the fluidic connection and thrust transmission system 6 is a complex system comprising a nozzle 61 defining a dispensing orifice 60, a flexible conduit 62, a connecting piece 63 and a force transmission member 64.
  • the nozzle 61 is intended to to be housed in the housing 55 formed by the core 5, as can be seen very clearly on the figures 3 and 7 .
  • the connecting piece 63 is intended to be fitted on the free end of the actuating rod 21 of the dispensing member 2. This is visible on the Figures 4, 5 , 8 and 9 .
  • the flexible conduit 62 thus makes it possible to connect the valve stem 21 to the dispensing orifice 60 while allowing a relative displacement between this nozzle 61 and this rod 21.
  • the flexible conduit 62 must be able to be deformed when the core 5 moves from the low axial position ( figure 3 ) to the high axial position ( figure 7 ).
  • the nozzle 61 moves not only axially with respect to the rod 21 but also in rotation around the rod 21. This leads to a complex deformation of the flexible conduit 62 between a visible position on the figure 1 and another visible position on the figure 8 .
  • the flexible conduit 62 makes a bend and a loop to reach the nozzle 61.
  • the flexible conduit forms only an elbow located in a single plane.
  • the flexible conduit is a particularly interesting element of the present invention because it allows a fluid connection between the valve stem 21 and the nozzle 61, while the pusher core 5 moves both in rotation and in translation.
  • the thrust transmission member 64 is here advantageously made integrally with the connection piece 63. It is even possible to make the flexible duct 62 integrally with the connection piece 63.
  • the transmission member of FIG. push consists of two arms 64 which extend diametrically opposite to the connecting end 63. The two arms 64 are respectively engaged in the two slots 34 formed by the sleeve 32 of the hoop 3, as can be see it very clearly on the figure 7 . Thus, the two arms 64 can move axially in translation but can not rotate due to the perfectly axial orientation of the slots 34. The two arms 64 have the function of transmitting the thrust force exerted by the core 5 on the 21.
  • the core 5 is positioned with its two thrust flanges 56 just above the ends of the arms 64 which project out of the slots 34, as can be seen on the figure 7 .
  • a force exerted downwards on the core 5 will cause the two thrust transmission arms 64 to move axially in their respective slots 34.
  • the thrust flanges 56 do not come into contact with the arm 64 in the upper axial position of the core 5, as shown in FIG. figure 7 .
  • the core 5 In the low axial position represented on the figure 3 the core 5 does not engage the arms 64, so that there is no coupling between the core 5 and the valve stem 21.
  • the core 5 can not be axially displaced in translation in the low axial position due to the configuration of the cam tracks 33.
  • the push cap 7 comes to cap the core 5 by wrapping it at least partially.
  • E core 5 and the cap 7 together form the pusher of the head.
  • the cap 7 comprises a thrust surface 71 on which the user can exert pressure with the aid of one or more fingers.
  • the cap 7 comprises a peripheral skirt 72 which is here in the form of a polygonal cylindrical section, preferably square.
  • the skirt 72 engages around the casing 51 of the core 5 by means of a latching system 74, 54.
  • the skirt 72 is dimensioned so that it fits slidably within the fairing 4 of the actuating means 40. This is visible on the figures 2 and 6 .

  • the hoop 3 is mounted perfectly static with respect to the dispensing member and the reservoir 1.
  • the displacement of the core 5 and the cap 7 is limited firstly by the extent of the grooves 311 and secondly by the extent of the cam tracks 33.
  • the cam tracks 33 alone could define the axial high and low abutment positions.
  • the grooves 311 could extend over the entire periphery of the base 31 and serve only as hooking means for the ring of the actuating means.
  • One principle of the invention lies in the fact of using a dressing element of the head, such as the fairing 40, as actuating means for moving the pusher, here constituted by the core 5 and the cap 7, with respect to the valve stem 21.
