Definitions

  • the present invention relates to a cover member (hoop) intended to be mounted on a fixing ring, the ring and the covering member together forming a fixing device for fixing a dispensing system, such as a pump or a valve , on the neck of a container.
  • the present invention also relates to a method of manufacturing such a cover member.
  • the present invention also relates to a fluid dispenser comprising a container, a dispensing system (pump or valve) and a fastening device incorporating a covering member of the invention.
  • Such fluid dispensers are frequently used in the fields of perfumery, cosmetics or even pharmacy.
  • the cover member of the ring may have several technical and / or aesthetic functions.
  • a first technical function of the cover member is to maintain or block the fixing ring on the neck of the container. Indeed, one can use the cover member to prevent the ring from deforming outwardly and thus to disengage the neck of the container.
  • Another aesthetic function of the covering member is to dress the fixing ring so as to give it an aesthetic appearance. The covering member is then produced with materials and shapes that make it attractive to the eye.
  • the cover member may be made of plastic or metal.
  • the cover member performs an aesthetic or technical function, it is important that it is fixedly held on the fixing ring. In fact, the covering organ must not be able to be torn off easily from the ring by pulling on it. It is therefore necessary that the attachment between the cover member and the ring has a high resistance or held to traction.
  • the present invention aims to overcome the aforementioned drawbacks of the prior art by defining a cover member whose tensile strength and rotation is particularly important.
  • the present invention provides a cover member for mounting on a fixing ring, the ring and the cover member together forming a fastening device for securing a dispensing system, such as a pump or a valve, on a container neck, the covering member having a generally cylindrical general configuration and comprising an outer wall, and an inner wall intended to come into tight contact around the ring, the inner wall forming at least one long groove recessed from a base area, characterized in that said groove is formed of a plurality of groove segments separated by non-grooved areas so as to form a locally interrupted groove.
  • the inner wall of the cover member is provided with groove segments arranged in one or more lines.
  • groove segments arranged in one or more lines.
  • the grooves may be arranged substantially vertically, that is to say parallel to the axis of the cylindrical covering member.
  • the grooves may be disposed substantially horizontally so as to form interrupted annular grooves. It is also possible to form the grooves obliquely. The ends of the groove segments make it possible to improve the tensile strength and / or the rotation.
  • the ends participate amply in the tensile strength.
  • the ends participate greatly in the rotational behavior.
  • the ends participate in holding both in rotation and in traction.
  • the ends participate in holding the fact that the plastic material constituting the fixing ring flows in the segments and thus makes as many locking points that prevent pulling withdrawal or rotational movement.
  • the multiplication of segments makes it possible to obtain an important holding.
  • the ends of the segments provide a holding in the direction corresponding to the orientation of the grooves.
  • the segments of a groove are elongate in the longitudinal direction of the rib, each segment forming two ends and two long edges, the adjacent ends of two segments being separated by the base zone.
  • the long edges provide a hold in a given direction and the ends provide a hold in the perpendicular direction.
  • the segments are made by displacement of material so that each segment is bordered by clumps of displaced material.
  • These clusters of displaced material themselves constitute relief or hollow profiles which participate even more in holding the cover member on the fixing ring.
  • the present invention also defines a first method of manufacturing a cover member as defined above, comprising the following successive steps: a) producing a metal stamping cover member, then b) machining the segments by removing the material for forming interrupted grooves.
  • the only drawback with the material removal machining technique is that it generates metal chips or debris that are difficult to remove completely. Therefore, the present invention provides another method of manufacture wherein the machining step is by material displacement, not by material removal.
  • the material displacement machining technique has the advantage of not generating any metal chips or debris. In this case, one can for example perform this machining step by pushing or knurling.
  • the invention also defines a fluid dispenser comprising a container, a dispensing system and a fastener incorporating a cover member as defined above.
  • An interesting principle of the invention consists in producing a network of discrete groove segments, these segments being separated by smooth or raised zones, which will also participate, together with the segments, in the holding of the covering member on the fixing ring.
  • the cover member performs both technical and aesthetic functions. Indeed, the covering member is a member visible from the outside which therefore gives an aesthetic appearance. This is why the covering member will be designated in the rest of the description by a term frequently used in the fields of perfumery and cosmetics, namely wrapping band. The term dressing is particularly appropriate, since the hoop dresses the fixing ring, as will be seen below.
  • the hoop has been designated as a whole by reference numeral 1. It can be made of plastic or metal. It has a generally cylindrical general configuration with a hollow interior. More specifically, the hoop comprises a substantially cylindrical case 10 comprising a lower end 11 and an upper end which is extends inwardly in the form of a tucked flap 12. The edge of the tucked flap 12 defines an opening 13 which extends through the shank 10.
  • the shank 10 includes a visible outer wall 14 and an inner wall 15.
  • the inner wall 15 is provided with recessed grooves 16 with respect to a smooth cylindrical base area 151.
  • the grooves are formed from finished groove segments 17 which extend vertically, that is, ie, parallel to the axis X of the cylinder formed by the barrel 10.
  • the inner wall 15 of the barrel 10 is thus provided with 24 grooves 16 themselves each formed by 3 segments of grooves which extend in the direction of the groove .
  • the grooves 16 extend parallel to each other and are distributed on the wall equidistantly. Another provision is also possible.
  • the number of grooves can also vary. Referring to the figure 2 it can be seen that each groove 16 comprises 3 segments 17 which are separated by non-grooved or smooth zones. These non-grooved areas may be formed by the base area 151.
  • the segments 17 have an elongated configuration which is in the same longitudinal direction as the grooves 16. Thus, each segment forms two ends 171 and two long edges 172, as can be seen in FIG. see him on the figure 2 .
  • the segments can also be made with a less elongated configuration so that each segment has a rather punctual shape.
  • the grooves can be likened to a dashed or dashed line whose dashed lines consist of groove segments.
  • a feature of this first embodiment lies in the fact that the grooves 16 are vertical, that is to say that they extend parallel to the axis X of the cylinder formed by the barrel 10.
  • the grooves 16 do not advantageously extend not to the level of the lower end 11, but start a little higher leaving a lower area free of grooves. It is the same at the lower end of the barrel 10 which is also free of grooves.
  • the cover band 1 is intended to cooperate with a fixing ring 2 which has a configuration quite conventional for the field of perfumery and cosmetics.
  • the ring can be made of plastic.
  • the fixing ring 2 comprises a skirt 20 defining tabs 21 separated by vertical longitudinal slots 22. Each tab 21 internally forms fastening heads 23 which project inwards.
  • the tabs 21 are separated by the slots 22 so as to confer a certain deformation capacity to the tabs which will be necessary to engage the ring on the neck.
  • the skirt 20 is connected at its upper end to a plate 24 which extends inwardly forming a latching housing 25 whose function will be given below.
  • the ring 2 comprises a guide wall 26 which advantageously extends upwards in alignment with the skirt 20
  • a dispensing system 3 which is the occurrence of a pump, is engaged in the detent housing 25 of the ring 2.
  • the pump 3 comprises a body 31 defining at its lower end an inlet 32 and at its upper end a collar 33
  • the pump 3 also comprises an actuating rod 34 which is movable back and forth inside the body 3.
  • the actuating rod 34 protrudes out of the housing. body and receives an actuating head 35 which is here in the form of a pusher.
  • the actuating rod 34 is moved inside the body 31, which has the effect of dispensing a dose of fluid. This is a pump quite classic in the field of pharmacy or cosmetics.
  • the ring 2 is intended to fix the pump 3 on a container, which is here designated by the reference numeral 4.
  • This container which is only partially represented comprises a neck 40 which defines an opening communicating the interior of the container. container with the outside.
  • the collar 40 defines an annular upper end edge 41 and an outer peripheral shoulder 42.
  • the fixing ring 2 cooperates with this neck by engagement of the attachment heads 23 below the shoulder 42.
  • a neck seal 27 is compressed between the upper edge 41 and the plate 24 of the ring 2.
  • the heads 23 To reach below the shoulder 42, the heads 23 must first pass beyond the shoulder 42. This is possible because the tabs 21 can deform radially outwardly to pass the shoulder 42. Once the shoulder has passed, the heads 23 can at least partially be housed below the shoulder 42.
  • the trim band 1 is mounted on the fixing ring 2 so as to block the tabs 21 around the neck 40.
  • the inner wall 15 of the trim band comes into tight contact with the outer wall of the ring, which is here formed by the skirt 20 and the guide wall 26.
  • the inner diameter of the base area is preferably slightly smaller than the diameter of the fixing ring.
  • the plastic material constituting the ring 2 will flow in the groove segments 17.
  • figure 3 we see the trim band 1 engaged partially on the ring 2, namely only at the guide wall 26.
  • the figure 4 which shows in an enlarged way the detail of the figure 3 it can be seen that the segments 17 are filled with the constituent material of the ring 2.
  • the band 1 completely surrounds the ring 2 with the lower end 11 of the band located below the lower end of the ring and the flap returning bearing on the upper end of the guide wall 26.
  • the grooves 16 formed by the segments 17, are filled by the skirt 20 and the guide wall 26
  • the diameter of the hoop at the bottoms of the groove segments is advantageously substantially equal to the external diameter of the ring at the level of the skirt.
  • the vertical disposition of the grooves prevents any rotation of the hoop around the ring.
  • This rotational behavior is mainly provided by the edges 172 of the segments.
  • the ends of the segments also participate in the holding of the hoop on the ring, mainly with respect to the tensile strength to prevent the withdrawal of the hoop from the ring by pulling on the hoop .
  • the creep qualities of the plastic material have been well known for a long time. These creep characteristics allow the constituent plastic material of the ring to flow inside the segments.
  • the substantially perpendicular orientation of the ends relative to the edges thus ensures good resistance both in traction and in rotation. This is not the case with continuous grooves as in the aforementioned prior art documents.
  • Such locally interrupted grooves can be made in a variety of ways.
  • the grooves can be produced in one and the same manufacturing step, for example by molding plastics material. It suffices to provide a mold imprint capable of producing the separated segments. It is also possible to make such a metal band in a single stage of manufacture, such as by molding, although this is very practical.
  • the hoop of the invention is made in two successive steps, namely a first step of making a hoop by metal stamping so as to form the smooth inner wall, and then machining the segments by removal of material or displacement of material to form discontinuous grooves.
  • the material displacement machining technique is preferred since it does not generate chips or metal debris.
  • each segment 17 comprises two opposite ends 171 connected by two edges 172.
  • Each projection extends hollow with respect to the base zone 151 defined by the internal wall 15.
  • the segment 17 thus projects into hollow forming two flanks 174 converging towards a groove bottom 173.
  • the segment 17 thus has a substantially triangular section. This shape allows better penetration of the constituent material of the fixing ring. Since the segment was here obtained by displacement of material, for example by embossing or knurling, the segment is bordered by clusters of displaced material.
  • the trim band 1 'here comprises oblique grooves 16' which extend parallel to each other.
  • the angle of the oblique grooves 16 'with respect to the longitudinal axis of the hoop is approximately 45 °.
  • the grooves 16 ' are formed from segments 17 separated by the smooth zone 151. These segments 17 may be made with any technique such as for example the molding, removal or displacement of material. Due to the inclined orientation of the segments 17, they are arranged in the diamond manner with respect to the longitudinal axis of the hoop. This diamond arrangement ensures good resistance both in rotation and traction.
  • FIG 7 another embodiment of a hoop 1 "according to the invention is seen, in which the grooves 16" extend horizontally so as to form annular grooves locally. interrupted, which can also be performed by any technique.
  • the grooves 16 "ensure a very good tensile strength.
  • a principle of the invention can be seen in the fact of forming localized, point or discrete segments at the inner wall of a trim band, or more generally of a cover member, intended to be engaged around a pump or valve mounting ring.
