Definitions

  • the present invention relates to a fluid dispenser comprising a dispensing member such as a pump or a valve, a container forming a neck and a fastener for fixing the dispensing member on the neck of the container.
  • the fixing member comprises a skirt defining an inner wall intended to cooperate with the neck of the container.
  • Such dispensers using such a fastener are commonly used in the field of perfumery, cosmetics, or even perfumery to dispense fluid products.
  • fastener rings Such rings generally define a skirt which extends downwards, and which is intended to cooperate with a reinforced portion formed by the neck of the container. This reinforced or thickened portion often referred to as "carnette” projects outwardly and forms a lower shoulder.
  • the skirt of the ring comprises a continuous bead or snap heads intended to engage under the shoulder that forms the carnette.
  • the skirt may be continuous, or slit on its height to form tabs at the ends of which are formed the locking heads.
  • the skirt is split and forms lugs and snap heads, it is generally provided a trim band that caps and cover the skirt so as to block the snap heads under the shoulder of the carnette.
  • the cord or the detent heads cooperate with the shoulder of the carnette.
  • the skirt has no interaction with the cylindrical outer bearing surface of the carnette for attachment purposes.
  • Such a skirt, slit or not, is however easily subject to deformations because the cord or the heads must be put in place in force under the shoulder of the carnette.
  • this plastic deformation of the skirt takes place under the effect of the trim band during its assembly.
  • a continuous skirt equipped with a continuous internal snap cord it sometimes happens that the deformation of the skirt is visible from the outside.
  • the present invention aims to overcome the aforementioned drawbacks of the prior art by defining a fastener whose skirt does not externally undergo any deformation, and which can further achieve effective fixation without the use of the trim band to block it on the neck of the container.
  • said inner wall is formed with at least two longitudinal ribs extending over the height of the skirt, said ribs cooperating by plastic deformation with an external part of the neck.
  • the ribs of the present invention extend over the height of the carnette, and advantageously still below the carnette so that the contact of the skirt with the collar is carried out over a large part of the height of the skirt.
  • the ribs define an internal diameter smaller than the external diameter of the neck before mounting the fastener on the neck, so that the ribs are deformed plastically on an external bearing surface of the neck after assembly. Since the ribs extend longitudinally and are spaced apart from each other, they can be relatively easily deformed plastically on the neck carnette without damaging or deforming the outer wall of the skirt.
  • the reinforced portion or carnette is formed with at least one retention relief in which the ribs penetrate by plastic deformation.
  • said at least one relief extends over the periphery of the reinforced portion.
  • the relief may for example be in the form of one or more circular grooves formed in the substantially cylindrical external surface of the Carnette.
  • the relief may for example be in the form of one or more circular grooves formed in the substantially cylindrical external surface of the Carnette.
  • said at least one profile extends over the height of the reinforced portion, advantageously in the form of a vertical groove, said profile having a width less than the width of a rib so as to maintain the rib by deformation plastic in said profile.
  • the profile is no longer peripheral, but vertical through the collar carnette.
  • the profile has a decreasing width from the upper end of the neck. The profile is preferably wider than the rib at the upper end of the neck and necessarily less wide than the rib at its lower end. This allows on the one hand to facilitate the introduction of the rib in the groove, and on the other hand, to retain the rib in the bleeding by a harpooning effect.
  • the skirt comprises longitudinal internal recesses located radially behind the ribs and formed in the thickness of the skirt, so that the ribs can be deformed radially outwards in their respective recesses without deforming the outer wall of the skirt.
  • the internal recesses allow deformation of the internal ribs without affecting the outer wall of the skirt. This allows to premount a fret on the skirt.
  • the hoop may advantageously be in contact with the outer wall of the skirt over its entire periphery, including at the internal recesses.
  • internal recesses means recesses that do not open on the outer wall of the skirt which can therefore remain perfectly cylindrical circular.
  • the recesses are open or open at the lower end of the skirt and are therefore in the form of blind holes extending axially in the thickness of the wall of the skirt from its lower end. And to allow good elastic deformation of the ribs, it is advantageous that the recesses are wider than the ribs.
  • the fixing member comprises a covering band which at least partially covers the skirt. Since the ribs are deformable without deforming the outer wall of the skirt, the trim band can be shown on the fastener before mounting on the neck of the container. Thus, the fastener and the hoop can be mounted as a unitary assembly on the neck of the container.
  • the fixing member comprises a ring 2, for example made of molded plastic material, which forms a receiving housing 2I intended to receive by snapping into force a dispensing member (not shown) such as a valve or a pump.
  • a dispensing member such as a valve or a pump.
  • the valve or the pump forms on its body a reinforced collar adapted to snap into the housing 21.
  • the actuating rod of the valve or the pump passes through an opening 24 formed in the ring.
  • the receiving housing 21 is connected on its outer periphery to a plate 22 intended to come into bearing contact on a seal 4 interposed between the plate 22 and the upper end of the neck of the container.
  • the plate 22 is connected on its outer periphery to a skirt 20 which has a substantially cylindrical outer shape.
  • the skirt 20 extends downwardly from the plate 22 but may also extend upward as shown in FIG. figure 1b .
  • the carnette extends to the upper end of the neck 10 which is formed a sealing ring 14 on which the flexible seal 4 is deformed. The carnette extends downward for a distance and then forms a shoulder to connect the cylindrical portion of reduced diameter of the neck.
  • the skirt 20 has an inner wall formed with a plurality of ribs 23 which extend vertically over part or all of the height of the skirt 20.
  • these ribs 23 are eight regularly distributed on the inner periphery of the inner wall of the skirt 20.
  • the ribs 23 advantageously extend over a height greater than that of the carnette 11.
  • the ribs 23 define a dummy cylinder passing through the ends of the ribs: this dummy cylinder has a diameter smaller than the external diameter of the carnette 11 so that the ribs 23, once the skirt 20 mounted on the neck 10 of the container 1, are plastically deformed against the substantially cylindrical outer surface of the carnette 11.
  • this dummy cylinder has a diameter smaller than the external diameter of the carnette 11 so that the ribs 23, once the skirt 20 mounted on the neck 10 of the container 1, are plastically deformed against the substantially cylindrical outer surface of the carnette 11.
  • they can advantageously extend to below the shoulder of the carnette of way to marry this shoulder, which contributes to the hanging of the skirt on the collar. It is also possible to form the outer bearing of the carnette 11 with a profile to improve the attachment of the ribs.
  • the outer surface of the carnette 11 is formed with a profile that is in the form of an annular groove 12 which extends over all or part of the periphery of the carnette. It is also possible to provide several profiles of this type. Thus, the ribs can penetrate plastic creep inside these profiles and thus improve the attachment of the skirt 20 on the neck 10. When the carnette 11 is provided with such profiles or grooves, the ribs do not need to extend below the shoulder of the carnette. In other words, a hooking of the ring on the neck can be achieved without the skirt cooperating with the shoulder of the carnette, unlike the aforementioned prior art.
  • a profiled outer surface of the carnette is sufficient to achieve effective maintenance of the ribs of the skirt on the collar. Since the ribs are arranged separately and are only point reinforcements in the direction of the introduction of the ring on the neck, they can deform without deforming the skirt 20 on its outer wall.
  • the attachment of the skirt 20 to the collar is achieved without the need for a trim band 3, as shown in FIG. figure 1b and which serves in the fasteners of the prior art to block the detent heads under the shoulder of the carnette.
  • the trim band 3 has only an aesthetic function and can be pre-assembled on the ring 2 before it is mounted on the neck of the container. This is indeed possible because the plastic deformation of the ribs does not cause deformation of the skirt 20 at its outer wall. It is therefore possible in some applications to dispense with the trim band 3.
  • the ring 20 is also formed with ribs 23 which extend vertically over a portion of the height of the skirt. As in the previous embodiment, these ribs 23 cooperate with the carnette 11 of the neck 10 of the container. According to the invention, several vertical grooves can be made in the carnette 11. These profiles or bleeds can extend from the top to the bottom of the carnette, so that the carnette is interrupted at this location, but the bleeding can also s' extend only on a part of the height of the carnette from its upper end leaving the lower end of the carnette intact. In the embodiment used to illustrate the present invention, the kerf 15 extends right through the carnette.
  • carnette 11 is formed with two such bleeds.
  • more than two grooves of this type may be provided, for example regularly distributed on the periphery of the neck.
  • the ribs 23 formed on the skirt 20, which are also two in number are adapted to be inserted inside the grooves 15 of the carnette.
  • the grooves or profiles 15 of the carnette have a width less than the width of the ribs 23 so that the ribs 23 are deformed plastically against the edges of the grooves 15.
  • the width of the grooves 15 is decreasing from of the upper end of the neck, so that at the upper end of the neck, the width of the grooves is greater than the width of the ribs, and that at the lower end of the grooves, the width is less than the width of the ribs 23.
  • the ribs 23 can be inserted into force in the grooves 15.
  • the oblique edges of the grooves 15 form a harpooning profile 16, for example located at the lower end of the grooves 15. It is also possible to design bleeding shapes with one or more harpooning profiles formed on the edges of the grooves other than at their lower end.
  • trim band 3 can also be pre-assembled before mounting the ring on the neck, since the deformation of the ribs does not cause any deformation of the outer wall of the skirt 20.
  • the third embodiment shown on the figures 4 and 5 is a variant of the first embodiment of Figures la and 1b.
  • the skirt 20 is here formed with longitudinal internal recesses 26 which extend over the height of the skirt. These recesses 26 are internal since they do not open on the inner wall 202 or on the outer wall 201. They extend from the lower end 203 of the skirt 20 upwards and are therefore under the blind hole shape opening on the lower end 203 of the skirt and extending upward axially in the thickness of the wall of the skirt without interfering with the inner wall and the outer wall of the skirt. These recesses may for example be made using a pin which enters the mold from the lower end of the skirt.
  • the recesses 26 are separated from the outer wall 201 by wall segments 28 and the inner wall 202 by other wall segments 27 on which the longitudinal internal ribs 23 are formed. Therefore, a recess 26 is always associated to a rib 23, and the rib is located radially in front of the recess. In other words, the recesses 26 are located just behind the ribs 23 if one starts from the center of the fastener, so that the ribs can deform radially outwards in the recesses, especially when their mounting on the neck of the container. During this deformation of the ribs 23, only the wall segments 27 are deformed while the wall segments 28 undergo no deformation.
  • the outer wall 201 of the skirt 20 does not deform during assembly of the ring on a container neck. It is thus possible to mount a ring 3 on the ring before mounting the ring on the container neck.
  • the hoop 3, which has a substantially cylindrical body 30 with an outer wall 32 and an inner wall 33 can come into contact with the outer wall 201 of the skirt over its entire periphery as can be seen on the figure 5 .
  • the fastener can be mounted on a neck with the hoop 3 mounted on the ring 2 as shown in FIG. figure 4 .
  • the recesses are wider than the ribs.
  • the ribs 23 may, for example, be deformed radially inwards in the recesses 26 at the wall 13 of the neck 10 while conforming to the profile of the lower shoulder of the thickening 11. It should be noted that with these longitudinal ribs 23 which advantageously extend over the entire height of the skirt, it is possible to achieve a fastening on a neck whose thickened portion 11 may vary in height. This was not the case with the devices of the prior art using teeth or snap cords intended to be housed under this shoulder.
  • longitudinal or vertical ribs formed on the inner wall of the skirt are used: these ribs are plastically deformable, for example by creep, on the substantially cylindrical outer wall of the neck which is advantageously provided with profiles of hanging.
  • the collar is not necessarily provided with a carnette.
  • the deformation of the ribs may be radial or tangential.
