Definitions
- the present invention relates to a fluid dispenser comprising a fluid reservoir provided with a neck internally defining an opening upwards and communicating with the interior of the reservoir and externally at least one external hooking shoulder facing downwards.
- the dispenser also comprises a dispensing head mounted on the neck of the reservoir and comprising a dispensing member, such as a pump or a valve, and a fastening member engaged both with the neck of the reservoir and the valve member.
- the fastener comprises a skirt forming at least one internal hooking projection capable of axially engaging hooking below the hooking shoulder of the neck.
- Such dispensers are frequently used in the fields of perfumery, cosmetics or even pharmacy.
- document FR2948344 which describes a fixing system for removably fixing a dispensing member (pump or valve) on a reservoir neck.
- This system includes:
- a fixing ring comprising flexible axial tabs capable of hooking around the tank neck, the tabs being separated by axial slots,
- the sleeve forms several locking sectors intended to come into engagement with the tabs in order to block them around the neck and several unlocking sectors out of contact with the ring.
- the sleeve is movable in rotation around the ring between a mounting position in which the locking sectors are in engagement with the tabs, and a dismantling position in which the locking sectors are located at the slots to allow the tabs to engage. deform to free themselves from their grip with the collar.
- the sleeve must be able to turn around the ring, which means that the ring must be locked in rotation on the neck,
- the gestures are not intuitive, because they first involve turning the sleeve to a precise angle, then pulling on the sleeve to forcefully disengage the flexible tabs of the fixing ring from below the collar . Without written instructions for use, it is not possible to remove a dispensing head from the neck with this fastening system.
- WO2009 / 150351 describes a dispenser comprising a reservoir with a threaded neck and a fixing member comprising a deformable and malleable skirt intended to come into engagement with the threaded neck, and a rigid hoop. engaged around the skirt to radially push the skirt against the threaded neck so as to deform the skirt against the thread of the neck to create a thread imprint in the skirt.
- the skirt of the fastener is therefore brought into engagement with the threaded neck by a radial inward movement, and not an axial displacement by rotation, as is the case with conventional threaded skirts.
- the skirt Before the skirt is fitted for the first time on a threaded neck, the skirt has no net imprint: it is only during the radial thrust carried out using the hoop that the net imprint is created by plastic deformation. of the deformable and malleable skirt.
- the material constituting the deformable and malleable skirt plastically flows around the threads of the neck of the reservoir to reach a final state with a satisfactory thread impression.
- This dispenser of the prior art thus makes it possible to mount the skirt around the neck without rotation and then makes it possible to remove the skirt from the neck by unscrewing.
- This dispenser therefore meets a recycling requirement by allowing the separation of these constituent elements.
- the object of the present invention is to provide another type of removable attachment, the assembly of which also takes place by pure axial thrust, but which implements a snap-fit or spear without deformation / creep of material and without the aid of a band. or a locking sleeve.
- the release of the ring (j u P e ) is carried out simply by a natural and intuitive movement of rotation of the ring (skirt) around the neck, but without the aid of a thread.
- the present invention provides a fluid dispenser comprising:
- a fluid reservoir provided with a neck internally defining an axial opening facing upwards and communicating with the interior of the reservoir, the neck (1) externally defining at least one horizontal hooking shoulder facing downwards,
- a dispensing head mounted axially on the neck of the reservoir, the head comprising a dispensing member, such as a pump or a valve and a fixing ring engaged both with the neck of the reservoir and the dispensing member , the fixing ring comprising a skirt comprising at least one internal hooking projection which is received below said at least one horizontal hooking shoulder, characterized in that said at least one horizontal hooking shoulder is formed at level of an oval base of the neck which forms an oval outer wall having a horizontal cross section of generally oval shape, except at the level of said at least one horizontal hooking shoulder.
- the internal hooking projection is formed at the level of a skirt of the neck which has a horizontal cross section of generally oval shape, so that the skirt substantially surrounds without play the oval base of the neck with the internal hooking projection (s) engaged under the respective horizontal hooking shoulder (s).
- the oval base can also form at least one release ramp, the hooking projection, initially in hooking engagement below its respective horizontal hooking shoulder, being forced radially towards the outside on the release ramp by rotating the skirt around the oval base of the neck, thus freeing the hooking projection from its hooking socket from below the hooking shoulder.
- the release ramp connects two neck zones which are radially offset and located axially at the same level, namely a bottom zone located axially below a horizontal attachment shoulder and the oval outer wall.
- the rotation of the skirt makes it possible to disengage the hooking projection (s) from below the respective hooking shoulder by urging it (or them) radially towards the exterior by means of ramps, which are distinct from the hooking shoulders.
- the attachment of the projection under the shoulder is provided entirely by the skirt, without the aid of a locking band or sleeve.
- the ramp (s) can be qualified as "vertical” because its greatest slope is horizontal.
- the oval base can form at least one attachment recess (and preferably two) which extends recessed from the oval outer wall, this attachment recess forming the shoulder. horizontal attachment, the bottom zone and advantageously at least one release ramp.
- the hooking recess may be partially or entirely surrounded by the oval outer wall and constitute only the only one defect in "ovality" of the oval outer wall.
- the oval outer wall can therefore be perfectly cylindrical, except at the location of the attachment recess (s).
- the oval base defines two parts of high curvature and two parts of low curvature
- the skirt defines two sectors of high curvature and two sectors of low curvature, said at least one hooking shoulder.
- horizontal being located at the level of at least a portion of low curvature
- said at least one internal hooking projection being located at the level of at least one sector of low curvature.
- the oval base forms at least one radial expansion ramp axially above the horizontal attachment shoulder to elastically deform the skirt so that the internal attachment projection can engage by elastic relaxation below. of its respective horizontal hooking shoulder.
- This expansion ramp may be in the form of a simple ridge, slope or cam facing outward and upward and over which the internal hooking projection can slide with friction.
- the neck can comprise a circular cylindrical chimney which extends axially upwards from the oval base, this circular cylindrical chimney being provided with two buttresses arranged diametrically opposed, each buttress forming an angular indexing ramp which extends radially outwards and upwards, connecting the circular cylindrical chimney to the oval outer wall.
- the outer diameter of the chimney is less than the smallest dimension of the oval base, so that an annular rim is formed by the oval base all around the chimney.
- the fixing ring can comprise an annular flange from which the skirt extends downwards, the skirt defining two sectors of high curvature and two sectors of low curvature, the two sectors of low curvature being separated. of the annular flange by horizontal slots to give a capacity for radial deformation to the two sectors of low curvature. Instead of these two horizontal slits, we can also provide four vertical slots which separate the sectors from each other.
- the retaining ring may include a circular cylindrical mounting sleeve which extends upwardly from the annular flange, this mounting sleeve overhanging the oval skirt with a trim band being frictionally engaged. around the mounting sleeve, this covering hoop surrounding the oval skirt at a radial distance and advantageously coming into contact with an annular plate of the neck.
- the oval outer wall can define two horizontal bars arranged diametrically opposed at the level of parts of small curvature, each horizontal bar comprising axially below it a hooking recess and axially above it a ramp. radial expansion, a horizontal hooking shoulder being defined at the junction of the hooking recess and the horizontal bar.
- the skirt can define two low curvature sectors arranged diametrically opposed and each forming an internal hooking projection, a horizontal slot being formed axially above each low curvature sector.
- the neck of the reservoir has, in horizontal cross section, an oval configuration at which the skirt of the fixing member is hooked.
- This oval configuration is used to free the fixing ring from its attachment by mutual rotation. Release by rotation is permitted or facilitated by the presence of release ramps which will induce local radial expansion of the skirt.

- Figure 2 is an exploded perspective view of a fixing ring and a neck according to the invention, with an interposed neck seal,
- Figure 3 is a perspective view in the assembled state of the fixing ring and the neck of Figure 2,
- Figure 4 is a perspective view from the back of the fixing ring of the invention.
- Figure 5a is a vertical sectional view of the dispenser of Figure 1
- Figure 5b is a horizontal sectional view along line c-c of the dispenser of Figure 5a.
- the fluid product dispenser shown in FIG. 1 to illustrate the present invention comprises two distinct parts or sub-assemblies, namely a fluid product reservoir R and a dispensing head T intended to be mounted on the reservoir to together constitute the dispenser. .
- the fluid reservoir R is only partially shown in the figures. Only the neck 1 and part of the tray R1 of the reservoir R has been shown in the figures.
- the neck 1 projects axially upwards from the plate S which already forms part of the body of the reservoir.
- the neck 1 internally defines an opening 10 which is oriented upwards and which communicates the interior of the reservoir with the exterior.
- the opening 10 is delimited by an annular upper edge 131 of the neck 1.
- the neck 1 comprises or forms an oval base 11 which extends upwards from the plate R1.
- This oval base 11 forms an oval cylindrical outer wall 110 having a horizontal cross section of generally oval shape.
- the oval cylindrical outer wall 110 thus has two parts of high curvature 11 a and two parts of low curvature 11 b.
- the oval cylindricity of the oval cylindrical outer wall 110 is interrupted by two hooking recesses 12 which extend horizontally recessed. These hooking recesses 12 are formed at the level of the two low curvature parts 11b and are therefore arranged diametrically opposed.
- Each hooking recess 12 forms the bottom zone 120, a horizontal hooking shoulder 121 and at least a release ramp 122.
- the horizontal hooking shoulder 121 is formed by the upper edge of the recess 12 which forms a sharp edge promoting hooking.
- the release ramp 122 is formed by a side edge of the recess 12, which smoothly joins the oval cylindrical outer wall 110. There may be one or two recess release ramp (s) 12. The lower edge of the recess 12 may be located at or near the plate R1.
- the oval outer wall 110 defines two horizontal bars 112, which are also arranged diametrically opposed at low curvature portions 11b of the oval base 11. Above each horizontal bar 112 is formed a radial expansion ramp 113.
- the neck 1 also includes a circular cylindrical chimney 13 which extends axially upwards from the oval base 11.
- a circular cylindrical chimney 13 which extends axially upwards from the oval base 11.
- two flat areas 114 in the shape of a crescent moon form the junction between the oval base 11 and the circular cylindrical chimney 13.
- These flat areas 114 have a maximum width at the level of the parts of strong curvature 11a and end at the point. level of the two small curvature parts 11 b.
- the outer diameter of the circular cylindrical chimney 13 is less than the smallest dimension of the oval base 11, separating the two low curvature parts 11b.
- the two radial expansion ramps 113 are arranged between the two flat areas 114 and thus connect the chimney 13 in an inclined manner to the horizontal bars of the base 11.
- This circular cylindrical chimney 13 is provided with two buttresses 14, which are arranged in diametrically opposed at the level two parts of strong curvature 11a.
- Each buttress 14 forms an angular indexing ramp 141 which extends radially outwardly connecting the circular cylindrical chimney 13 to the oval outer wall 11.
- the buttresses 14 interrupt the flat areas 114.
- the reservoir R with a neck 1 thus profiled, is preferably made of a rigid plastic material.
- the dispensing head T essentially comprises two constituent members, namely a dispensing member P, which may be a pump or a valve, and a fixing ring F engaged both with the profiled neck 1 of the reservoir and the member. distribution P.
- a pusher B can be mounted on the distribution member P to actuate it. It is also possible to imagine a dispensing member without a pusher, for example in the form of an applicator, a stopper or a pot lid.
- the distribution member P comprises a body P1 defining at one of its ends an inlet for the fluid from the reservoir.
- the body P1 forms a fixing flange P2 which projects radially outwards.
- the distribution member P also comprises an actuating rod P3 which projects upwards from the body P1 and which is axially movable back and forth relative to the body.
- a return spring urges the actuating rod P3 in its most extended position outside the body.
- the actuating rod P3 internally defines a delivery channel for the fluid pressurized inside the body P1. This is a completely classic design for a pump or a valve in the fields of perfumery, cosmetics or even pharmacy. Since the internal structure of the distribution member P is not critical to the present invention, it will not be further described.
- the pusher B is mounted on the free end of the actuating rod P3 of the distribution member P.
- the fluid from the actuating rod P3 is conducted through an internal channel to a distribution orifice O formed by the pusher.
- the pusher includes a bearing surface on which the user can press with one or more fingers to move the pusher B axially back and forth. In this way, the fluid product, in metered form or not, is distributed through the dispensing orifice O. Again, this is a completely conventional design for a fluid dispenser.
- the fixing ring F is advantageously made of a plastic material that is not very deformable, making it possible to create relatively deformable, while other areas are more rigid.
- the ring F is preferably made in one piece.
- the ring F comprises a skirt 2 which engages around the neck 1 of the reservoir, and more precisely around the oval base 11.
- the skirt 1 therefore surrounds the circular cylindrical chimney 13.
- the skirt 2 is oval in horizontal section. It is generally cylindrical.
- the skirt 2 thus has two sectors of high curvature 2a and two sectors of low curvature 2b.
- the skirt 2 forms two internal attachment projections 21 which are housed in the attachment recesses 12, just below the horizontal attachment shoulders 121.
- the internal hooking projections 21 are formed at the level of the two low curvature sectors 2b.
- the protrusions 21 partially or completely fill the recesses 12.
- the protrusions 21 can be in the form of horizontal elongated ribs, the ends of which are preferably rounded or soft, as can be seen in FIGS. 4 and 5b. Thus, they can cooperate smoothly with the release ramps 122 of the recesses 12.
- the fixing ring F also forms a receiving housing Fp for the fixing flange P2 and an annular flange Fg which serves to crush a neck gasket G on the upper edge 14 of the neck 1. It can be seen in the figures that the two sectors of low curvature 2b, where the projections 21 are formed, are separated from the annular flange Fg by horizontal slots 22 to give increased radial deformation capacity to the two sectors of low curvature 2b.
- the fixing ring F also comprises or forms a circular cylindrical mounting sleeve Ff which extends upwards from the annular flange Fg, this mounting sleeve Ff overhanging the oval skirt 2. It is conceivable that the outer wall of the skirt 2 is flush with the outer wall of the sleeve Ff at the level of its two sectors of strong curvature 2a, as can be seen in FIG. 4.
- a covering band 3 can be engaged in friction around the mounting sleeve Ff , so that this band 3 surrounds the oval skirt 2 at a radial distance and advantageously comes into contact with an annular plate R1.
- the purpose of hoop 3 is purely aesthetic in relation to the F ring.
- the dispensing head T is brought onto the neck 1 with or without prior angular orientation: it can quite simply be deposited by gravity on the neck 1. Without angular orientation, it is unlikely that the high curvature sectors 2a and the low curvature sectors 2b of the oval skirt 2 are respectively in agreement with the high curvature portions 11a and the low curvature portions 11b of the base. oval 11. It does not matter, since the two angular indexing ramps 141 will automatically rotate the oval skirt 2 until the axes of the ovals are aligned. The skirt 2 will thus be able to reach an intermediate mounting position without exerting any constraint on the distribution head: only gravity has acted, in cooperation with the two ramps 141.
- An axial thrust on the distribution head T makes it possible to force the hooking projections 21 on the radial expansion ramps 113, which has the effect of elastically deforming the skirt 2 radially outwards, until it passes over the bars 112, beyond which it can elastically relax under the hooking shoulders 121 in the recesses 12. The final mounting position is then reached. The axial tensile strength is only ensured by the latching of the hooking projections 21 under the hooking shoulders 121.
- the hoop 3 can be engaged around the skirt 2 before mounting the head T on the neck, given that the hooking tabs 21 can be deformed radially outwards, since they are positioned offset inwardly, thus leaving a radial clearance space between the hooking tabs 21 and the hoop 3.
- the dispensing head T can easily be reassembled on the neck 1, after dismantling, by a user without any difficulty, because the reassembly operation is identical to that of assembly.
- the oval shape of the base 11 and of the skirt makes it possible to impose a relative angular orientation, which ensures the engagement of the projections 21 in the recesses 12. It also makes it possible to elastically deform the skirt. 2 to release the projections 21 from below the shoulders 121.
- the three functions of hooking, elastic deformation and release are essential, while the angular orientation function provided by the ramps 141 is optional.
