Description

Organe de fixation de pompe Pump fixing device
La présente invention concerne un organe ou bague de fixation destiné(e) à monter un organe de distribution sur un col d’un réservoir. Ce genre de bague de fixation est utilisée dans les domaines de la parfumerie, de la cosmétique ou de la pharmacie pour monter de manière définitive ou amovible des organes de distribution, tels que des pompes, des valves, des bouchons, etc., sur un réservoir de produit fluide, de granulés ou de poudre. The present invention relates to a fixing member or ring for mounting a dispensing member on a neck of a reservoir. This type of fixing ring is used in the fields of perfumery, cosmetics or pharmacy to permanently or removably mount distribution members, such as pumps, valves, caps, etc., on a reservoir for fluid, granules or powder.
Dans l’art antérieur, il est connu de réaliser l’organe de fixation par moulage de manière plastique. L’organe de fixation définit généralement un axe vertical de symétrie et comprend une jupe en prise avec (dans ou autour) le col, un plateau annulaire reposant axialement sur le col, avec un joint optionnel écrasé entre eux, et une douille de réception dans laquelle la collerette de fixation de l’organe de distribution est reçue fixement. Cette douille de réception définit un logement de réception qui est formé par une broche de moulage qui est retirée en force lors du démoulage. Ce logement de réception comprend une nervure annulaire d’entrée qui fait saillie vers l’intérieur et qui réduit ainsi l’ouverture du logement de réception. La collerette de fixation du corps de l’organe de distribution est maintenue dans le logement de réception par cette nervure annulaire d’entrée. En général, la nervure annulaire d’entrée se présente sous la forme d’un bourrelet annulaire continu de section constante. In the prior art, it is known to produce the fixing member by molding in a plastic manner. The fastener generally defines a vertical axis of symmetry and comprises a skirt engaged with (in or around) the neck, an annular plate resting axially on the neck, with an optional seal squashed between them, and a receiving sleeve in which the fixing collar of the dispensing member is fixedly received. This receiving sleeve defines a receiving housing which is formed by a molding pin which is forcefully withdrawn during demolding. This receiving housing includes an annular inlet rib which protrudes inwardly and thereby narrows the opening of the receiving housing. The flange for fixing the body of the dispensing member is held in the receiving housing by this annular inlet rib. Typically, the entry annular rib is in the form of a continuous annular bead of constant section.
On comprend aisément que, lors du démoulage, le broche de moulage qui forme le logement de réception exerce une contrainte importante sur la nervure annulaire d’entrée. La broche de moulage, réalisée en métal, déforme donc la nervure. Le but est que cette déformation soit temporaire et élastique, et non pas définitive. La nervure ne doit pas être râpée, raclée, retroussée, ou encore laminée par la broche. Il faut veiller à ce que la nervure reste le plus intacte possible. Bien souvent, la nervure est légèrement abîmée. Afin de conférer une déformabilité élastique accrue à la nervure lors du démoulage, il est courant de la former au niveau d’une paroi cylindrique qui autorise une dilatation réversible. It is easily understood that, during demolding, the molding pin which forms the receiving housing exerts a significant stress on the annular inlet rib. The molding pin, made of metal, therefore deforms the rib. The aim is for this deformation to be temporary and elastic, and not permanent. The rib should not be grated, scraped, rolled up, or rolled by the pin. Care must be taken to ensure that the rib remains as intact as possible. Often the rib is slightly damaged. In order to impart increased elastic deformability to the rib during demolding, it It is common to form it at the level of a cylindrical wall which allows reversible expansion.
Cependant, dans certains cas, une tenue supérieure de la collerette dans le logement de réception est exigée. Mais l’on ne peut pas augmenter la saillie radiale de la nervure, car le débrochage n’est plus possible sans l’abimer. La paroi cylindrique où est formée la nervure a aussi des limites de déformation élastique. However, in some cases, a better hold of the flange in the receiving housing is required. However, the radial protrusion of the rib cannot be increased, because unplugging is no longer possible without damaging it. The cylindrical wall where the rib is formed also has elastic deformation limits.
Dans d’autres cas, la nervure doit être placée plus bas, par exemple au niveau du plateau annulaire, qui n’offre qu’une capacité de déformation élastique très limitée. Le débrochage conduit alors très souvent à l’endommagement de la nervure annulaire. In other cases, the rib must be placed lower, for example at the level of the annular plate, which offers only a very limited elastic deformation capacity. Unplugging then very often leads to damage to the annular rib.
Le but de la présente invention est de préserver au maximum l’intégrité de la nervure annulaire d’entrée lors du démoulage. En d’autres termes, la nervure doit rester dans son état de moulage initial après le retrait de la broche de moulage. Un autre but est de ne pas compliquer l’opération de moulage et de démoulage, ni d’imposer un matériau plastique particulier. The object of the present invention is to preserve as much as possible the integrity of the annular inlet rib during demolding. In other words, the rib must remain in its initial molding state after removal of the mold pin. Another aim is not to complicate the molding and demolding operation, nor to impose a particular plastic material.
Pour ce faire, la présente invention propose que la nervure annulaire d’entrée comprennent des segments de retenue destinés à venir en prise avec la collerette de fixation et des segments de démoulage destinés à venir en prise avec la broche de moulage lors du démoulage. Ainsi, seuls les segments de démoulage sont contraints par la broche de démoulage et les segments de retenue restent non sollicités par la broche et sont donc intacts. Peu importe que les segments de démoulage soient abîmés lors du démoulage, puisqu’ils ne participent pas à la tenue de la collerette. Les segments de démoulage agissent comme des organes de protection ou des boucliers pour les segments de retenue, en se plaçant en première ligne dans le chemin de débrochage de la broche. On peut aussi dire que le bourrelet saillant conventionnel a été segmenté et que seule une partie du bourrelet va remplir sa fonction de maintien de la collerette dans le logement, alors que l’autre partie du bourrelet a été dédiée au démoulage ou débrochage pour préserver la partie dédiée au maintien. Avantageusement, les segments de retenue et les segments de démoulage comprennent respectivement des faces de retenue et des faces de came qui sont tournées vers l’intérieur du logement de réception, les faces de came définissant une pente par rapport à l’axe vertical qui est plus grande que celle des faces de retenue. Ainsi, la pente plus importante des segments de démoulage assure que la broche, lors de son retrait, va attaquer les faces de came des segments de démoulage et s’éloigner des faces de retenue des segments de retenue. Bien entendu, juste après le moulage et avant le démoulage, la broche de moulage est en contact à la fois des faces de retenue et des faces de came, puisque c’est elle qui les a formées. Cependant, lors du démoulage, la broche va seulement rester en contact avec les faces de came, du fait de leur pente accrue : les faces de retenue vont être déplacées radialement vers l’extérieur sans contact avec la broche, mais par l’intermédiaire des segments de démoulage, qui sont déplacés radialement vers l’extérieur, quitte même à être détériorés par la broche au passage. To do this, the present invention proposes that the annular inlet rib comprise retaining segments intended to engage with the fixing flange and demold segments intended to engage with the molding pin during demolding. Thus, only the mold release segments are constrained by the release pin and the retaining segments remain unstressed by the pin and are therefore intact. It is irrelevant whether the demolding segments are damaged during demolding, since they do not participate in the holding of the collar. The mold release segments act as protective members or shields for the retainer segments, placing themselves first in the spindle drawout path. It can also be said that the conventional protruding bead has been segmented and that only part of the bead will fulfill its function of maintaining the collar in the housing, while the other part of the bead has been dedicated to demoulding or unplugging to preserve the part dedicated to maintenance. Advantageously, the retaining segments and the release segments respectively comprise retaining faces and cam faces which are turned towards the inside of the receiving housing, the cam faces defining a slope with respect to the vertical axis which is larger than that of the retaining faces. Thus, the greater slope of the mold release segments ensures that the pin, when withdrawn, will engage the cam faces of the release segments and move away from the retaining faces of the retaining segments. Of course, just after molding and before demolding, the molding pin is in contact with both the retaining faces and the cam faces, since it is she who formed them. However, during demolding, the spindle will only remain in contact with the cam faces, due to their increased slope: the retaining faces will be moved radially outwards without contact with the spindle, but by means of demolding segments, which are moved radially outwards, even if it means being damaged by the spindle in passing.
A titre d’exemple non limitatif, la pente des faces de came par rapport à celle de faces de retenus est supérieure de 1 à 10 degrés, avantageusement de 2 à 6 degrés et de préférence de l’ordre de 3 à 5 degrés. By way of non-limiting example, the slope of the cam faces relative to that of the retaining faces is greater by 1 to 10 degrees, preferably 2 to 6 degrees and preferably of the order of 3 to 5 degrees.
Selon une caractéristique de l’invention, les segments de retenue et les segments de démoulage peuvent être agencés de manière alternée. Ils peuvent être jointifs ou séparés par des fentes. On peut par exemple prévoir dix segments de retenue et dix segments de démoulage intercalés. According to a characteristic of the invention, the retaining segments and the release segments can be arranged alternately. They can be contiguous or separated by slits. One can for example provide ten retaining segments and ten interposed mold release segments.
Selon un autre aspect, les segments de retenue peuvent être plus saillants radialement vers l’intérieur que les segments de démoulage. En variante ou en plus, les segments de retenue peuvent présenter une hauteur axiale plus grande que celle des segments de démoulage. Les segments de démoulage peuvent se présenter grossièrement sous la forme d’un mini segment de retenue. In another aspect, the retaining segments may protrude more radially inwardly than the release segments. As a variant or in addition, the retaining segments may have an axial height greater than that of the release segments. The release segments may be roughly in the form of a mini retainer segment.
D’autre part, les faces de démoulage peuvent être décalées axialement vers le bas par rapport aux face de retenue, de sorte que la nervure annulaire d’entrée présente une configuration supérieure crénelée. La présente invention présente un avantage tout particulier lorsque la nervure annulaire d’entrée est située à proximité axiale ou sensiblement au même niveau axial que le plateau annulaire, de sorte que la capacité de déformation élastique lors du démoulage est réduite. On the other hand, the demoulding faces can be offset axially downwards with respect to the retaining faces, so that the annular inlet rib has a crenellated upper configuration. The present invention has a very particular advantage when the annular inlet rib is located in axial proximity or substantially at the same axial level as the annular plate, so that the capacity for elastic deformation during demolding is reduced.
La présente invention définit également un distributeur de produit fluide comprenant un réservoir de produit fluide, un organe de distribution, tel qu’une pompe ou une valve, et un organe de fixation tel que défini ci-dessus, pour monter l’organe de distribution sur le réservoir de produit fluide. The present invention also defines a fluid product dispenser comprising a fluid product reservoir, a dispensing member, such as a pump or a valve, and a fixing member as defined above, for mounting the dispensing member. on the fluid reservoir.
L’esprit de l’invention repose sur le fait de protéger les zones de retenue de la nervure d’entrée du logement de réception qui vont venir en contact avec la collerette de fixation avec des zones de came qui sont en première ligne sur le chemin de débrochage et qui vont encaisser l’impact de la broche, au risque d’être abîmées. On garantit ainsi que les zones de retenue sortent intactes du débrochage et pourront pleinement remplir leur fonction de retenue. The spirit of the invention is based on the fact of protecting the retaining zones of the inlet rib of the receiving housing which will come into contact with the fixing collar with cam zones which are in the first line on the path. disconnection and which will withstand the impact of the spindle, at the risk of being damaged. This ensures that the retention zones leave the draw-out intact and can fully fulfill their retention function.
L’invention sera maintenant plus amplement décrite en référence aux dessins joints, donnant à titre d’exemple non limitatif, un mode de réalisation de l’invention. The invention will now be more fully described with reference to the accompanying drawings, giving by way of non-limiting example an embodiment of the invention.

Le distributeur de la figure 1 comprend un réservoir de produit fluide R, un organe de distribution P et un organe de fixation 1 qui fait l’objet de la présente invention. Optionnellement, le distributeur peut encore comprendre une frette d’habillage F qui est engagée autour de l’organe de distribution 1. The dispenser of Figure 1 comprises a reservoir of fluid R, a dispensing member P and a fixing member 1 which is the subject of the present invention. Optionally, the dispenser can also include a covering band F which is engaged around the dispensing member 1.
Le réservoir de produit fluide R n’est pas critique pour la présente invention, de sorte qu’il peut être réalisé en n’importe quel matériau approprié et présenter une forme quelconque. Le réservoir R comprend un col R1 qui fait saillie vers le haut et définit une ouverture R0 qui permet d’accéder à l’intérieur du réservoir. Le col R1 comprend un renfort annulaire R2 qui fait saillie vers l’extérieur. Ainsi, ce renfort R2 définit un épaulement annulaire orienté vers le bas. Le col R1 définit également un bord annulaire supérieur R3. The fluid reservoir R is not critical to the present invention, so it can be made of any suitable material and have any shape. The R reservoir includes an R1 neck that protrudes upward and defines an R0 opening that provides access to the interior of the reservoir. The R1 collar includes an R2 annular reinforcement that protrudes outward. Thus, this reinforcement R2 defines an annular shoulder oriented downwards. The neck R1 also defines an upper annular edge R3.
L’organe de distribution P peut être une pompe ou une valve. Il comprend un corps P1 définissant une collerette de fixation P2 et équipée d’un tube plongeur P3. L’organe de distribution P comprend également une tige d’actionnement P4 qui est coiffé par un poussoir P5. Ainsi, par appui sur le poussoir P5, la tige d’actionnement P4 est enfoncée à l’intérieur du corps P1 , mettant ainsi une dose de produit fluide sous pression dans le cas d’une pompe ou ouvrant un clapet de sortie dans le cas d’une valve. Là encore, le type d’organe de distribution P n’est pas critique pour la présente invention. Il suffit que le corps P1 comprenne une collerette saillante de fixation P2. The distribution member P can be a pump or a valve. It comprises a body P1 defining a fixing flange P2 and equipped with a plunger tube P3. The distribution member P also includes an actuating rod P4 which is capped by a pusher P5. Thus, by pressing on the pusher P5, the actuating rod P4 is pressed inside the body P1, thus putting a dose of fluid under pressure in the case of a pump or opening an outlet valve in the case of a pump. of a valve. Again, the type of distribution member P is not critical to the present invention. It suffices for the body P1 to include a protruding fixing collar P2.
L’organe de fixation 1 de l’invention présente une symétrie axiale selon un axe vertical X et comprend une jupe 11 qui vient en prise avec le col R1. Dans le mode de réalisation utilisé pour illustrer la présente invention, la jupe 11 comprend des dents de fixation 12 qui viennent en prise en dessous du renfort annulaire R2. La jupe 11 peut être continue, comme c’est le cas ici, ou encore fendue de manière à former des pattes souples séparées par des fentes. L’organe de fixation 1 comprend également un plateau annulaire 13 qui s’étend radialement vers l’intérieur à partir de l’extrémité supérieure de la jupe 11. Ce plateau annulaire 13 peut servir à écraser un joint de col G sur le bord annulaire supérieur R3 du col R1. Du fait de sa configuration annulaire, le plateau 13 présente une capacité de déformation radiale très réduite. L’organe de fixation 1 comprend aussi une douille de réception 14 qui s’étend vers le haut à partir de la périphérie interne du plateau 13. Cette douille de réception 14 comprend une partie cylindrique 141 qui s’étend vers le haut à partir de la périphérie interne du plateau 13 et une bride annulaire 142 qui s’étend radialement vers l’intérieur à partir de l’extrémité supérieure de la partie cylindrique 141. En son centre, la bride annulaire 142 forme une ouverture centrale 143 à travers laquelle s’étend la tige d’actionnement P4 de l’organe de distribution P. La paroi interne de la partie cylindrique 141 forme une nervure annulaire d’entrée 15 qui fait saillie radialement vers l’intérieur. Ainsi, la douille de réception 14 définit un logement de réception L dont l’entrée est réduite par la saillie de la nervure annulaire d’entrée 15. On peut voir sur la figure 1 que la collerette annulaire de fixation P2 de l’organe de distribution P est logée à l’intérieur de ce logement de réception L, entouré par la partie cylindrique 141 et pris en sandwich entre la nervure annulaire d’entrée 15 et la bride annulaire 142. L’organe de distribution P est ainsi maintenu de manière parfaitement stable, voire même étanche, à l’intérieur de la douille de réception 14. Il s’agit là d’une configuration tout à fait classique pour un organe de fixation dans le domaine de la parfumerie, de la cosmétique ou encore de la pharmacie. The fixing member 1 of the invention has axial symmetry along a vertical axis X and comprises a skirt 11 which engages with the neck R1. In the embodiment used to illustrate the present invention, the skirt 11 comprises fixing teeth 12 which engage below the annular reinforcement R2. The skirt 11 may be continuous, as is the case here, or else slit so as to form flexible tabs separated by slits. The fixing member 1 also comprises an annular plate 13 which extends radially inwardly from the upper end of the skirt 11. This annular plate 13 can be used to crush a neck gasket G on the annular edge. upper R3 of neck R1. Due to its annular configuration, the plate 13 has a very low radial deformation capacity. The fixing member 1 also comprises a receiving sleeve 14 which extends upwards from the internal periphery of the plate 13. This receiving sleeve receiving 14 comprises a cylindrical portion 141 which extends upwardly from the inner periphery of the plate 13 and an annular flange 142 which extends radially inwardly from the upper end of the cylindrical portion 141. At its center, the annular flange 142 forms a central opening 143 through which extends the actuating rod P4 of the distribution member P. The internal wall of the cylindrical part 141 forms an annular inlet rib 15 which protrudes radially inward. Thus, the receiving sleeve 14 defines a receiving housing L, the entry of which is reduced by the projection of the annular inlet rib 15. It can be seen in FIG. 1 that the annular fixing flange P2 of the distribution P is housed inside this receiving housing L, surrounded by the cylindrical part 141 and sandwiched between the annular inlet rib 15 and the annular flange 142. The distribution member P is thus held in such a manner. perfectly stable, or even waterproof, inside the receiving sleeve 14. This is a completely conventional configuration for a fixing member in the field of perfumery, cosmetics or even clothing. pharmacy.
La présente invention se situe au niveau de la nervure annulaire d’entrée 15 qui sera maintenant décrite en détail en référence aux figures 2, 3, 4a et 4b. The present invention is located at the level of the annular inlet rib 15 which will now be described in detail with reference to Figures 2, 3, 4a and 4b.
On peut tout de suite remarquer sur la figure 2 que la nervure annulaire d’entrée 15 n’est pas constante ou régulière sur sa périphérie. Au contraire, cette nervure annulaire 15 définit une alternance de segments de retenue 16 et de segments de démoulage 17 présentant des configurations différentes. Chaque segment de retenue 16 est bordé par deux segments de démoulage adjacents 17, et inversement. Les segments 16 et 17 peuvent être jointifs, ou au contraire séparés par des fentes. On peut également remarquer que les segments de retenue 16 présentent une hauteur ou étendue axiale supérieure à celle des segments de démoulage 17. Sur la figure 3, on peut également remarquer que les segments de retenue 16 présentent une épaisseur radiale supérieure à celle des segments de démoulage 17. En somme, les segments de retenue 16 sont plus hauts et/ou plus saillants que les segments de démoulage 17. It can immediately be seen in FIG. 2 that the annular inlet rib 15 is not constant or regular on its periphery. On the contrary, this annular rib 15 defines an alternation of retaining segments 16 and of release segments 17 having different configurations. Each retaining segment 16 is bordered by two adjacent mold release segments 17, and vice versa. The segments 16 and 17 can be contiguous, or on the contrary separated by slots. It can also be noted that the retaining segments 16 have a height or axial extent greater than that of the release segments 17. In FIG. 3, it can also be noted that the retaining segments 16 have a radial thickness greater than that of the segments of the mold. release 17. In short, the segments retainer 16 are higher and / or more protruding than the release segments 17.
En se référant aux figures 4a et 4b, on peut remarquer que les segments de retenue 16 comprennent chacun une face de retenue 161 qui est inclinée vers le haut et vers l’intérieur du logement de réception L. On peut dire que cette face de retenue 161 forme le premier contrefort du segment de retenue 16 à l’intérieur du logement de réception L. On comprend que cette face de retenue 161 va venir en prise avec le bord inférieur de la collerette annulaire P2 de l’organe de distribution P, si l’on se réfère à nouveau à la figure 1 . Referring to Figures 4a and 4b, it can be seen that the retaining segments 16 each include a retaining face 161 which is inclined upward and inwardly of the receiving housing L. It can be said that this retaining face 161 forms the first buttress of the retaining segment 16 inside the receiving housing L. It is understood that this retaining face 161 will engage with the lower edge of the annular flange P2 of the distribution member P, if we refer again to Figure 1.
On peut également remarquer que les segments de démoulage 16 forment chacun une face de came 171 qui est également orientée vers le haut et vers l’intérieur du logement de réception L. Les faces de came 171 ne sont pas situées au même niveau axial que les faces de retenue 161 : en effet, on peut voir que les faces de came 171 sont disposées légèrement plus bas que les faces de retenue 161 , de manière à conférer une forme crénelée à la nervure annulaire 15. It can also be noted that the demolding segments 16 each form a cam face 171 which is also oriented upwards and towards the interior of the receiving housing L. The cam faces 171 are not located at the same axial level as the retaining faces 161: in fact, it can be seen that the cam faces 171 are arranged slightly lower than the retaining faces 161, so as to impart a crenellated shape to the annular rib 15.
La figure 4a est une vue en coupe à travers une nervure de retenue 16. Sa face de retenue 161 s’étend avec une pente qui fait un angle a par rapport à la verticale Y. La figure 4b est une vue en coupe à travers une nervure de démoulage 17. Sa face de came 171 présente une pente faisant un angle b par rapport à la verticale Y. Selon l’invention, l’angle b est plus grand que l’angle a. A titre d’exemple, l’angle a peut être de 38,5°, alors que l’angle b peut être de 42°. Ces valeurs sont données à titre purement indicatif. En effet, la différence entre les angles a et b, toujours en faveur de l’angle b, peut varier de 1 à 10°, avantageusement de 2 à 6°, de préférence entre 3 et 5°. Figure 4a is a sectional view through a retaining rib 16. Its retaining face 161 extends with a slope which makes an angle a with respect to the vertical Y. Figure 4b is a sectional view through a release rib 17. Its cam face 171 has a slope forming an angle b with respect to the vertical Y. According to the invention, the angle b is greater than the angle a. For example, angle a can be 38.5 °, while angle b can be 42 °. These values are given for information only. Indeed, the difference between the angles a and b, always in favor of the angle b, can vary from 1 to 10 °, advantageously from 2 to 6 °, preferably between 3 and 5 °.
L’organe de fixation 1 est réalisé de manière classique par injection/moulage de matière plastique. Une broche de moulage (non représentée) définit une empreinte extérieure correspondant aux parois intérieures de l’organe de fixation 1 . La broche de moulage comprend donc une tête de moulage qui vient former l’intérieur du logement de réception L. La tête de la broche de moulage comprend donc des profils en relief et en creux qui correspondent en négatif aux segments de retenue 16 et aux segments de démoulage 17. Après injection de la matière plastique autour de la broche de moulage, il faut retirer cette broche de moulage de l’intérieur de l’organe de fixation 1. Cependant, la nervure annulaire d’entrée 15 s’étend radialement vers l’intérieur, de sorte qu’il faut retirer la broche de moulage en force en déformant la douille de réception 14, et plus particulièrement sa paroi cylindrique 141 . Ceci est tout à fait classique dans le moulage des organes de fixation dans le domaine de la parfumerie, de la cosmétique ou encore de la pharmacie. The fixing member 1 is produced in a conventional manner by injection / molding of plastic material. A molding pin (not shown) defines an outer cavity corresponding to the inner walls of the fastener 1. The molding pin therefore comprises a molding head which forms the interior of the receiving housing L. The head of the molding pin therefore comprises raised and recessed profiles which correspond negatively to the retaining segments 16 and to the segments. of release 17. After injection of the plastic material around the molding pin, this molding pin must be removed from the inside of the fixing member 1. However, the annular inlet rib 15 extends radially towards the end. 'interior, so that it is necessary to remove the molding pin by deforming the receiving sleeve 14, and more particularly its cylindrical wall 141. This is quite conventional in the molding of fasteners in the field of perfumery, cosmetics or even pharmacy.
Selon l’invention, la tête de la broche de moulage va d’abord venir en prise avec les segments de démoulage 17 et laisser les segments de retenue sans contrainte. Ainsi, les segments de démoulage 17 seront éventuellement ou probablement abimés ou détériorés par la broche de moulage, mais les segments de retenue 17 resteront intacts et pourront remplir leur fonction de retenue de la collerette annulaire P2. En effet, étant donné que la face de came 171 des segments de démoulage 17 présente une pente plus forte ou plus grande que celle des faces de retenue 161 , la broche de démoulage va venir en prise appuyée contre les faces de came 171 et s’éloigner des faces de retenue 161 , les laissant ainsi intactes. According to the invention, the head of the molding pin will first engage the release segments 17 and leave the retainer segments unconstrained. Thus, the release segments 17 will possibly or probably be damaged or deteriorated by the molding pin, but the retaining segments 17 will remain intact and will be able to fulfill their function of retaining the annular flange P2. In fact, given that the cam face 171 of the demoulding segments 17 has a steeper or greater slope than that of the retaining faces 161, the demoulding pin will come into engagement pressed against the cam faces 171 and s'. moving away from the retaining faces 161, thus leaving them intact.
Les segments de démoulage 17 de l’invention permettent de réaliser des organes de fixation avec une tenue plus importante ou une nervure annulaire disposée à proximité du plateau annulaire 13, qui réduit la déformation radiale. En effet, il importe peu que les segments de démoulage 17 soient abimés, dans la mesure où les segments de retenue 16 restent intacts ou pratiquement intacts. Afin de garantir l’intégrité des segments de retenue 16, il est préférable que les segments de démoulage soient situés à proximité directe des segments de retenue, et soient en nombre suffisant. Dans l’exemple utilisé pour illustrer la présente invention, il y a dix segments de retenue et dix segments de démoulage. Les segments de retenue et de démoulage peuvent s’étendre angulairement sur des étendues identiques ou similaires. The mold release segments 17 of the invention make it possible to produce fasteners with greater hold or an annular rib disposed near the annular plate 13, which reduces radial deformation. Indeed, it does not matter whether the release segments 17 are damaged, insofar as the retaining segments 16 remain intact or practically intact. In order to ensure the integrity of the retainer segments 16, it is preferable that the release segments are located in close proximity to the retainer segments, and are in sufficient number. In the example used to illustrate the present invention, there are ten retainer segments and ten release segments. The retainer and release segments may extend angularly over the same or similar extents.
Grâce à l’invention, on dispose d’un organe de fixation dont la nervure annulaire 15 du logement de réception L remplit pleinement sa fonction, étant donné que les segments de retenue 16 sont préservés par les segments de démoulage 17. Thanks to the invention, there is a fixing member whose annular rib 15 of the receiving housing L fully fulfills its function, being since the retaining segments 16 are preserved by the mold release segments 17.
