Description

"Biberon comportant des moyens perfectionnés de fixation de la bague sur le goulot" "Bottle with improved means of fixing the ring on the neck"
La présente invention concerne un biberon .The present invention relates to a bottle.
DOMAI N E TECHN IQU E DE L'I NVENTIONTECHNICAL DOMINION OF THE I NVENTION
De façon connue, un tel biberon, par exemple d'allaitement est du type comportant un corps inférieur en forme de bouteille comportant un goulot axial supérieur de remplissage, une tétine comportant une collerette annulaire radiale inférieure appliquée sur une portée annulaire supérieure du goulot, et une bague de fixation de la tétine sur le corps qui comporte une bride annulaire radiale qui est traversée par la tétine et qui s'étend en regard de la face supérieure de la collerette de la tétine et qui comporte une jupe latérale annulaire cylindrique qui s'étend axialement vers le bas et qui est fixée de manière démontable sur le goulot par des moyens de fixation .In known manner, such a bottle, for example breastfeeding is of the type comprising a lower body in the form of a bottle having an upper axial filler neck, a teat having a lower radial annular flange applied on an upper annular bearing surface of the neck, and a nipple fixing ring on the body which comprises a radial annular flange which is traversed by the nipple and which extends opposite the upper face of the collar of the nipple and which comprises a cylindrical annular side skirt which s' extends axially downwards and which is removably attached to the neck by fixing means.
ÉTAT DE LA TECH N IQU ESTATE OF THE TECH N IQU E
Selon une première solution technique classique connue et utilisée commercialement de manière universelle, les moyens de fixation de la bague sur le col ou goulot du corps inférieur, aussi appelé flacon ou bouteille, sont constitués par un filetage formé sur la paroi latérale extérieure du goulot et par un taraudage complémentaire formé dans la paroi latérale intérieure en vis-à- vis de la jupe latérale de la bague de fixation .According to a first known conventional technical solution and used commercially in a universal manner, the fixing means of the ring on the neck or neck of the lower body, also called bottle or bottle, are constituted by a thread formed on the outer side wall of the neck and by a complementary tapping formed in the inner side wall vis-à-vis the side skirt of the fixing ring.
Ainsi, grâce à cette liaison par vissage, la collerette de la tétine, aussi appelée talon de la tétine, est immobilisée entre le bord supérieur du goulot et la portion en vis-à-vis de la face inférieure de la bride de la bague de fixation . Une telle conception des moyens de fixation dans lesquels le serrage est obtenu par vissage a pour inconvénient que la personne adulte, parent ou puéricultrice, n'est pas en mesure de maîtriser avec précision la course angulaire de serrage par vissage et cette personne n'interrompt le serrage que lorsqu'elle perçoit une difficulté à serrer davantage.Thus, thanks to this connection by screwing, the collar of the nipple, also called heel of the nipple, is immobilized between the upper edge of the neck and the portion vis-à-vis the underside of the flange of the ring. fixation . Such a design of fastening means in which the tightening is obtained by screwing has the disadvantage that the adult person, parent or nursery nurse, is not able to accurately control the angular travel tightening by screwing and this person does not interrupt the tightening only when it perceives a difficulty to tighten more.
Un serrage excessif peut provoquer une occultation , au moins partielle, des différentes entrées d'air généralement prévues sur la tétine. Dans ce cas, le biberon est «bloqué» et le liquide contenu dans le flacon , par exemple du lait d'allaitement, ne s'écoule plus à travers la tétine.Over-tightening may cause at least partial concealment of the different air intakes generally provided on the nipple. In this case, the bottle is "blocked" and the liquid in the bottle, for example breast milk, no longer flows through the pacifier.
L'utilisateur tente alors généralement de desserrer la collerette de la tétine en la dévissant, toujours sans aucune maîtrise de la précision du desserrage. Un dévissage ou desserrage excessif peut provoquer une fuite du liquide entre le bord supérieur du goulot et la face inférieure de la bride annulaire de la bague de fixation .The user then generally tries to loosen the collar of the nipple by unscrewing it, still without any control of the accuracy of loosening. Excessive unscrewing or loosening may cause liquid to leak between the upper edge of the neck and the underside of the annular flange of the retaining ring.
I l est ainsi souvent nécessaire pour l'utilisateur d'effectuer plusieurs opérations répétées de serrage et de desserrage, c'est- à-dire de vissage et de dévissage, pour aboutir à une position correcte approximative d'utilisation dans laquelle la collerette, ou talon , de la tétine est suffisamment serrée pour qu'il n'y ait pas de fuites, et pas trop serrée pour permettre l'entrée régulière de l'air dans le biberon . Un vissage excessif peut aussi avoir pour effet de déformer, voire de détériorer, la collerette de la tétine qui adopte alors une forme écrasée et déformée qui empêche l'entrée de l'air dans les zones prévues, à cet effet, en induisant de plus une fuite de liquide. La pression axiale de la bride de la bague de fixation sur la face supérieure de la collerette de la tétine n'est alors plus répartie angulairement de manière régulière sur toute la périphérie de la tétine. I I existe donc un besoin de disposer d'une nouvelle conception d'un biberon permettant d'une part à l'utilisateur de maîtriser avec précision et régularité le serrage appliqué à la collerette de la tétine lorsqu'il fixe la bague sur le corps et, d'autre part, de garantir une circulation de l'air, de l'extérieur vers l'intérieur du biberon , en passant notamment entre la bague de fixation et le goulot du corps du biberon .It is thus often necessary for the user to carry out several repeated tightening and loosening operations, that is to say screwing and unscrewing, to arrive at an approximate correct position of use in which the collar, or heel, the pacifier is tight enough so that there are no leaks, and not too tight to allow regular entry of air into the bottle. Excessive screwing can also have the effect of deforming or even deteriorating the collar of the nipple, which then adopts a crushed and deformed shape which prevents the entry of air into the zones provided, for this purpose, by inducing moreover leaking fluid The axial pressure of the flange of the fixing ring on the upper face of the collar of the nipple is then no longer angularly distributed evenly over the entire periphery of the nipple. There is therefore a need for a new design of a bottle allowing the user to control with precision and regularity the tightening applied to the collar of the pacifier when he fixes the ring on the body and on the other hand, to guarantee a flow of air from the outside to the inside of the bottle, passing in particular between the fixing ring and the neck of the body of the bottle.
On connaît du document EP-B1 -0.843.545 une conception d'un biberon dans lequel les moyens de fixation de la bague sur la partie supérieure du corps sont du type dit à baïonnette. La conformation en rampe inclinée des gorges qui reçoivent les ergots de fixation ne permettent néanmoins pas de maîtriser avec précision , et par une manoeuvre simple et unique, le serrage axial . De plus le passage de l'air entre la jupe latérale de la bague et les parties en vis-à-vis du tronçon d'extrémité supérieure du corps du biberon n'est nullement garanti de manière fiable.It is known from EP-B1 -0.843.545 a design of a bottle in which the fastening means of the ring on the upper part of the body are of the so-called bayonet type. The inclined ramp conformation of the grooves which receive the fixing lugs nevertheless do not allow precise control, and by a single and simple maneuver, the axial clamping. In addition the passage of air between the side skirt of the ring and the parts facing the upper end portion of the body of the bottle is not guaranteed reliably.
RESU ME DE L'I NVENTIONSUMMARY OF THE INVENTION
Afin de remédier à ces inconvénients, l'invention propose un biberon du type mentionné précédemment caractérisé en ce que les moyens de fixation du type à baïonnette comportent au moins un ergot qui s'étend radialement depuis la face latérale concave interne de la jupe latérale, ou depuis la face latérale convexe externe du goulot, et au moins une gorge en "L", apte à recevoir l'ergot, qui est formée dans la face latérale convexe externe du goulot, ou dans la face latérale concave interne de la jupe latérale respectivement, en regard de la face latérale concave interne de la jupe latérale, ou en regard de la face latérale convexe externe du goulot respectivement, et qui comporte un premier tronçon d'orientation générale verticale dont l'extrémité libre supérieure est débouchante axialement vers le haut pour permettre l'introduction et/ou l'extraction axiale de l'ergot, et un second tronçon d'orientation générale horizontale qui s'étend angulairement depuis l'extrémité inférieure du premier tronçon et dans lequel est reçu l'ergot lorsque la bague est verrouillée sur le goulot, et en ce que la face latérale interne concave de la bague, ou la face latérale externe convexe du goulot, comporte une série de nervures formées en relief qui coopèrent avec des portions en vis- à-vis de la face latérale externe convexe du goulot, ou de la face latérale interne concave de la bague respectivement, pour centrer radialement la bague, avec un jeu radial, par rapport au goulot. Selon d'autres caractéristiques de l'invention :In order to overcome these disadvantages, the invention proposes a bottle of the type mentioned above, characterized in that the bayonet type fixing means comprise at least one lug which extends radially from the internal concave lateral face of the lateral skirt, or from the external convex side face of the neck, and at least one "L" groove, adapted to receive the lug, which is formed in the external convex side face of the neck, or in the internal concave side face of the side skirt respectively, opposite the lateral concave side face of the lateral skirt, or facing the external convex side face of the neck respectively, and which comprises a first section of generally vertical orientation whose upper free end is open axially towards the high to allow the introduction and / or axial extraction of the lug, and a second portion of general horizontal orientation which extends angularly from the lower end of the first section and in which the lug is received when the ring is locked on the neck, and in that the side face concave inner ring, or the convex outer lateral side of the neck, comprises a series of ribs formed in relief which cooperate with portions vis-à-vis the convex outer side face of the neck, or the inner concave side face of the ring respectively, to radially center the ring, with a radial clearance, with respect to the neck. According to other features of the invention:
- le jeu radial s'étend sensiblement sur toute la hauteur de la bague ;the radial clearance extends substantially over the entire height of the ring;

Dans la description qui va suivre, pour faciliter sa compréhension ainsi que celle des revendications, on adoptera à titre non limitatif et sans référence à la gravité terrestre, la terminologie verticale pour l'orientation générale de l'axe principal du biberon et l'orientation horizontale pour les plans orthogonaux à l'axe vertical.In the following description, to facilitate its understanding as well as that of the claims, will be adopted without limitation and without reference to earthly gravity, the vertical terminology for the general orientation of the main axis of the bottle and the orientation horizontal for planes orthogonal to the vertical axis.
Des composants ou parties identiques, analogues ou similaires seront désignés par les mêmes références.Identical or similar components or parts will be designated by the same references.
On a représenté schématiquement à la figure 1 un biberon 10 qui est constitué de trois composants comportant un corps ou flacon inférieur 12, une tétine souple supérieure 14 et une bague supérieure de fixation 16.FIG. 1 diagrammatically shows a bottle 10 which consists of three components comprising a lower body or bottle 12, an upper flexible nipple 14 and an upper fixing ring 16.
L'ensemble présente un axe central vertical de symétrie A-A.The assembly has a vertical central axis of symmetry A-A.
De manière connue, le corps ou flacon inférieur comporte un goulot axial supérieur 18 de remplissage dont le diamètre moyen est inférieur à celui de la partie inférieure principale du corps. Le goulot se termine axialement par un bord supérieur d'extrémité libre 20 qui s'étend de manière continue dans un plan horizontal ou radial .In known manner, the lower body or bottle has an upper axial filler neck 18 whose average diameter is smaller than that of the main lower part of the body. The neck ends axially with an upper edge free end 20 which extends continuously in a horizontal or radial plane.
Le bord supérieur 20 présente, en section par un plan axial, un profil arrondi convexe. Le corps inférieur 12 avec son goulot supérieur 18 est par exemple réalisé par moulage en matière plastique rigide ou semi- rigide.The upper edge 20 has, in section by an axial plane, a convex rounded profile. The lower body 12 with its upper neck 18 is for example made by molding rigid or semi-rigid plastic material.
Le tronçon supérieur d'extrémité libre 22 du goulot 18 constitue une zone supérieure du goulot qui présente une épaisseur radiale réduite par rapport à l'épaisseur sensiblement constante de la paroi du corps 12 et du goulot 18.The upper end of the free end 22 of the neck 18 constitutes an upper zone of the neck which has a reduced radial thickness with respect to the substantially constant thickness of the wall of the body 12 and the neck 18.
Le goulot 18 est délimité latéralement par une paroi latérale intérieure cylindrique concave 21 et par une paroi latérale extérieure cylindrique convexe 24 qui déterminent entre elles l'épaisseur axiale « e » du goulot 18 et qui délimitent entre elles un tronçon ou zone inférieure 23 du goulot 18.The neck 18 is delimited laterally by a concave cylindrical inner side wall 21 and a convex cylindrical outer side wall 24 which determine between them the axial thickness "e" of the neck 18 and which delimit between them a lower section or zone 23 of the neck 18.
Les deux zones supérieure 22 d'épaisseur axiale réduite et inférieure 23 de plus grande épaisseur axiale « e » sont reliées entre elles par un chanfrein extérieur 25. La face latérale cylindrique externe convexe du goulot 18 présente ainsi un profil étage comportant le premier tronçon supérieur 22 qui est délimité axialement par le bord supérieur d'extrémité libre 20 et le deuxième tronçon inférieur 23 consécutif dont le diamètre externe est supérieur au diamètre externe du premier tronçon 22.The two upper regions 22 of reduced axial thickness and lower 23 of greater axial thickness "e" are interconnected by an outer bevel 25. The convex outer cylindrical lateral face of the neck 18 thus has a floor profile comprising the first upper section 22 which is delimited axially by the upper free end edge 20 and the second consecutive lower section 23 whose outer diameter is greater than the outer diameter of the first section 22.
Comme représenté aux figures 2 et 6, le goulot 18 comporte, agencées symétriquement et de manière diamétralement opposée, deux gorges 26 de verrouillage à profil en « L » qui sont formés, ici venues de matière par moulage, dans la paroi latérale extérieure convexe 24 de la zone inférieure 23 du goulot 18. Chaque gorge 26 est ainsi ouverte radialement vers l'extérieur dans la face latérale 24. Chaque gorge 26 comporte un premier tronçon 28 qui est ici d'orientation axiale verticale et dont l'extrémité libre supérieure débouche axialement vers le haut. Plus précisément, compte tenu des différentes épaisseurs axiales et de la profondeur axiale des différents tronçons de la gorge 26, qui est ici constante tout le long de la gorge, chaque premier tronçon axial 28 débouche essentiellement vers le haut au niveau du chanfrein 25 de raccordement entre les deux zones supérieure 22 et inférieure 23 du goulot 18. Chaque gorge 26 comporte un second tronçon 30 qui est ici d'orientation horizontale et qui s'étend angulairement depuis l'extrémité axiale inférieure 32 du tronçon vertical 28 sur un secteur angulaire alpha déterminé.As shown in FIGS. 2 and 6, the neck 18 comprises, arranged symmetrically and diametrically opposite, two L-shaped profile locking grooves 26 which are formed here integrally by molding in the convex outer lateral wall 24. of the lower zone 23 of the neck 18. Each groove 26 is thus open radially outwards in the lateral face 24. Each groove 26 comprises a first section 28 which is here of vertical axial orientation and whose upper free end opens axially upwards. More specifically, given the different axial thicknesses and the axial depth of the different sections of the groove 26, which is constant here all along the groove, each first axial section 28 opens essentially upwards at the connecting chamfer 25 between the two upper and lower zones 22 of the neck 18. Each groove 26 has a second section 30 which is here of horizontal orientation and which extends angularly from the lower axial end 32 of the vertical section 28 on an alpha angular sector determined.
Chaque second tronçon horizontal 30 est délimité angulairement par un fond d'extrémité borgne 34.Each second horizontal section 30 is defined angularly by a blind end base 34.
Chaque second tronçon horizontal 30 s'étend angulairement dans l'épaisseur du second tronçon inférieur 23 du goulot 18.Each second horizontal section 30 extends angularly in the thickness of the second lower section 23 of the neck 18.
Chaque gorge en « L » est ainsi constituée de deux tronçons consécutifs vertical 28 et horizontal 30. Chaque gorge 26 présente, tout le long de ses deux tronçons 28 et 30, une largeur constante de telle manière que chaque gorge 26 est, sur toute sa longueur, apte à recevoir et à être parcourue par un ergot complémentaire de verrouillage, qui sera décrit par la suite, qui coopère avec une gorge de verrouillage 26 associée pour constituer des moyens du type à baïonnette de fixation et de verrouillage de la bague 16 sur le goulot 18 du corps 12.Each "L" groove thus consists of two vertical consecutive sections 28 and 30 horizontal. Each groove 26 has, along its two sections 28 and 30, a constant width such that each groove 26 is, in all its length, adapted to receive and to be traversed by a complementary locking lug, which will be described later, which cooperates with a locking groove 26 associated to form means bayonet type fixing and locking the ring 16 on the neck 18 of the body 12.
La tétine 14 est, de manière connue, réalisée par moulage dans un matériau souple et est constituée essentiellement d'une partie supérieure d'extrémité libre 36 munie d'une série de trous ou orifices 38 permettant au bébé ou nourrisson de téter et d'absorber le liquide contenu dans le biberon , et d'une partie inférieure 40 en forme de collerette annulaire radiale qui s'étend latéralement vers l'extérieur.The teat 14 is, in known manner, made by molding in a flexible material and consists essentially of a free end upper portion 36 provided with a series of holes or holes 38 allowing the baby or infant to suck and absorb the liquid contained in the bottle, and some lower 40 in the form of a radial annular flange which extends laterally outwardly.
La collerette inférieure 40 est délimitée verticalement vers le bas par une face horizontale inférieure 42 qui est apte à venir en appui, verticalement vers le bas, et à être serrée contre le bord supérieur d'extrémité libre 20 du goulot 18 qui constitue une portée d'appui pour la collerette.The lower flange 40 is delimited vertically downwards by a lower horizontal face 42 which is able to come into abutment, vertically downwards, and to be clamped against the upper free end edge 20 of the neck 18 which constitutes a bearing surface. support for the collar.
La collerette 40 est aussi délimitée verticalement vers le haut par une face horizontale supérieure 44. Enfin, la collerette 40 est délimitée latéralement par son bord périphérique extérieur 46.The flange 40 is also delimited vertically upwards by an upper horizontal face 44. Finally, the flange 40 is delimited laterally by its outer peripheral edge 46.
De manière connue et non représentée en détails, la tétineIn known manner and not shown in detail, the pacifier
14, et par exemple la face inférieure 42 de sa collerette 40, comporte des moyens permettant la circulation et le passage de l'air, de l'extérieur vers l'intérieur, entre le bord supérieur 20 et la collerette 40.14, and for example the lower face 42 of its collar 40, comprises means for the circulation and the passage of air, from the outside towards the inside, between the upper edge 20 and the collar 40.
Comme représenté à la figure 4, la bague supérieure de fixation, et de verrouillage, 16 est une pièce moulée en matière plastique rigide ou semi-rigide et elle est constituée pour l'essentiel d'une bride supérieure annulaire radiale 50 et d'une jupe latérale 52.As shown in FIG. 4, the upper fixing and locking ring 16 is a molded piece made of rigid or semi-rigid plastic material and it consists for the most part of an annular radial upper flange 50 and a side skirt 52.
La bride supérieure 50 s'étend sensiblement dans un plan radial, de l'extérieur vers l'intérieur et elle est délimitée radialement par un bord circulaire intérieur 54 de profil arrondi qui permet le passage et qui est traversé par la partie supérieure 36 de la tétine 14. La bride supérieure 50 est délimitée verticalement vers le bas par une face radiale inférieure 56 qui est apte à coopérer avec la portion en vis-à-vis de la face supérieure 44 de la collerette 40 de la tétine 14 pour serrer la collerette 40 axialement entre la face inférieure 56 de la bride 50 et le bord supérieur d'extrémité libre 20 du goulot 18.The upper flange 50 extends substantially in a radial plane, from the outside to the inside and is delimited radially by an inner circular edge 54 of rounded profile which allows the passage and which is traversed by the upper part 36 of the The upper flange 50 is delimited vertically downwards by a lower radial face 56 which is adapted to cooperate with the portion facing the upper face 44 of the flange 40 of the nipple 14 to tighten the flange. 40 axially between the lower face 56 of the flange 50 and the upper free end edge 20 of the neck 18.
Comme illustré aux figures 3 à 5, la jupe latérale 52 est d'épaisseur sensiblement constante, et sensiblement égale à l'épaisseur de la bride supérieure 50. La jupe 52 présente un profil étage, c'est-à-dire qu'elle comporte un premier tronçon supérieur 58 de plus petit diamètre extérieur qui est délimité radialement par une face latérale intérieure cylindrique concave 60, et comporte un deuxième tronçon inférieur 62 de plus grand diamètre extérieur qui est délimité radialement par une face latérale intérieure concave 64 légèrement tronconique.As illustrated in FIGS. 3 to 5, the lateral skirt 52 is of substantially constant thickness, and substantially equal to the thickness of the upper flange 50. The skirt 52 has a floor profile, that is to say it comprises a first upper section 58 of smaller outer diameter which is delimited radially by a concave cylindrical inner side face 60 , and comprises a second lower section 62 of larger outer diameter which is delimited radially by a concave inner side 64 slightly frustoconical.
Enfin , la jupe latérale 52 est délimitée verticalement vers le bas par un bord inférieur d'extrémité libre 66. La bague 16 comporte ici, de manière complémentaire aux deux gorges en « L » 26, deux ergots de verrouillage diamétralement opposés 68. Le nombre d'ergots, et de gorges, est de préférence compris entre 2 et 4, et ils sont de préférence répartis angulairement de manière uniforme. Chaque ergot de verrouillage 68 est un ergot de forme générale cylindrique et d'orientation radiale et son diamètre externe est légèrement inférieur à la largeur de la gorge complémentaire 26 de façon qu'il puisse y être introduit et y circuler. Afin de lui conférer une certaine élasticité radiale, chaque ergot de verrouillage cylindrique 68 comporte un évidement intérieur débouchant 70.Finally, the lateral skirt 52 is delimited vertically downwards by a lower free end edge 66. The ring 16 here comprises, complementary to the two "L" grooves 26, two diametrically opposite locking lugs 68. The number pins, and grooves, is preferably between 2 and 4, and they are preferably angularly distributed uniformly. Each locking pin 68 is a generally cylindrical pin and radially oriented and its outer diameter is slightly less than the width of the complementary groove 26 so that it can be introduced and circulate there. In order to give it a certain radial elasticity, each cylindrical locking pin 68 has an opening inner recess 70.
Chaque ergot de verrouillage 68 s'étend radialement vers l'intérieur depuis la face latérale concave 64 et il est agencé au droit bord inférieur 66. Sur toute sa hauteur axiale, la face latérale intérieure concave 64 du tronçon inférieur 62 de la jupe latérale 52 de la bague 16 comporte une série de nervures de centrage 72, qui sont ici au nombre de six réparties angulairement de manière régulière. Chaque nervure de centrage 72 est ici un « godron » qui est réalisé venue de matière par moulage et qui est formé en relief, radialement vers l'intérieur, dans la face concave 64. Chaque nervure de centrage 72 se présente sous la forme d'une barrette verticale de profil arrondi convexe.Each locking lug 68 extends radially inwardly from the concave side face 64 and is arranged at the lower right edge 66. Throughout its axial height, the concave inner side face 64 of the lower section 62 of the lateral skirt 52 the ring 16 comprises a series of centering ribs 72, which are here six in number distributed angularly in a regular manner. Each centering rib 72 is here a "godron" which is produced integrally by molding and which is formed in relief, radially inwards, in the concave face 64. Each centering rib 72 is in the form of a vertical bar of convex rounded profile.
Comme on peut le voir à la figure 2, le diamètre intérieur D1 commun aux six nervures de centrage radial 72 est sensiblement égal au diamètre extérieur D2 de la zone inférieur 23 de plus grand diamètre extérieur du goulot 18.As can be seen in FIG. 2, the inside diameter D1 common to the six radial centering ribs 72 is substantially equal to the outside diameter D2 of the lower zone 23 of greater outside diameter of the neck 18.
Ainsi, en position montée et verrouillée de la bague 16 sur le goulot 18, il existe un jeu radial sensiblement constant « J » entre la face latérale intérieure concave 64 de diamètre intérieur D3 du tronçon inférieur 62 de la jupe latérale 52 de la bague 16, et la face latérale extérieure convexe 24 de la zone inférieure 23 du goulot 18 de diamètre extérieur D2.Thus, in the mounted and locked position of the ring 16 on the neck 18, there is a substantially constant radial clearance "J" between the concave inner side face 64 of inner diameter D3 of the lower section 62 of the lateral skirt 52 of the ring 16. and the convex outer side face 24 of the lower zone 23 of the neck 18 of outside diameter D2.
Bien entendu, la longueur radiale des ergots de verrouillage 68 et la profondeur radiale des gorges de verrouillage 26 sont telles qu'elles n'interfèrent pas avec la fonction de centrage radial assuré par la coopération des nervures 72 avec la face latérale convexe 24 de manière à garantir l'existence, sensiblement sur toute la périphérie, du jeu radial J qui permet la libre circulation de l'air entre le goulot 18 et la jupe latérale 52 de la bague de verrouillage 16.Of course, the radial length of the locking lugs 68 and the radial depth of the locking grooves 26 are such that they do not interfere with the radial centering function provided by the cooperation of the ribs 72 with the convex side face 24 to guarantee the existence, substantially over the entire periphery, of the radial clearance J which allows the free flow of air between the neck 18 and the lateral skirt 52 of the locking ring 16.
La mise en place et le verrouillage de la bague 16 sur le goulot 18 s'effectue, après avoir mis en place la tétine 14 (soit en appui sur le bord supérieur d'extrémité libre 20 du goulot 18, soit à l'intérieur de la bague 16) en introduisant axialement de haut en bas simultanément les deux ergots de verrouillage 68 dans les tronçons verticaux 28 des gorges en vis-à-vis 26.The establishment and locking of the ring 16 on the neck 18 is performed, after having put in place the nipple 14 (either resting on the upper free end edge 20 of the neck 18, or inside of the ring 16) by introducing axially from top to bottom simultaneously the two locking lugs 68 in the vertical sections 28 of the grooves vis-à-vis 26.
L'utilisateur poursuit le mouvement relatif de haut en bas de la bague 16 par rapport au goulot 18 jusqu'à ce que les ergots de verrouillage 68 viennent en butée contre les extrémités inférieures 32 des tronçons verticaux d'introduction 28.The user continues the relative movement from top to bottom of the ring 16 with respect to the neck 18 until the locking lugs 68 abut against the lower ends 32 of the vertical insertion sections 28.
L'utilisateur, qui a perçu cette mise en butée axiale, provoque alors une rotation de la bague 16 par rapport au goulot 18 de manière que les ergots 68 parcourent simultanément les tronçons horizontaux 30 jusqu'à venir en butée angulaire contre les fonds ou extrémités borgnes 34.The user, who has perceived this axial abutment, then causes rotation of the ring 16 with respect to the neck 18 so that the lugs 68 simultaneously traverse the horizontal sections 30 to come into angular abutment against the funds or blind ends 34.
La conformation en « L » des gorges de verrouillage 26 permet ainsi de maîtriser automatiquement le serrage axial de la collerette radial 40 de la tétine 14 entre le bord supérieur 20 et la face inférieure 56 de la bride 50 de la bague de verrouillage 16. Cette conformation permet aussi de limiter la course angulaire de verrouillage de la bague 16 sur le goulot 18, en évitant ainsi tout phénomène de frottement excessif entre les surfaces en contact de la collerette 40, du goulot 18 et de la bague 16.The "L" conformation of the locking grooves 26 thus makes it possible to automatically control the axial clamping of the radial flange 40 of the nipple 14 between the upper edge 20 and the lower face 56 of the flange 50 of the locking ring 16. conformation also makes it possible to limit the angular stroke of locking of the ring 16 on the neck 18, thus avoiding any phenomenon of excessive friction between the surfaces in contact with the flange 40, the neck 18 and the ring 16.
La présence des nervures de centrage assure, lors de l'introduction axiale de la bague 16 sur le goulot 18, un centrage radial automatique mutuel de ces deux composants et donc la présence du jeu radial « J » . La mise en place de la bague 16 axialement sur le goulot 18 est notamment facilitée par la présence du chanfrein 25 qui procure un effet d'auto centrage des nervures 72 dès que leurs bords d'extrémité inférieure 73 viennent au contact du chanfrein 25.The presence of the centering ribs ensures, during the axial insertion of the ring 16 on the neck 18, a mutual automatic radial centering of these two components and therefore the presence of the radial clearance "J". The establishment of the ring 16 axially on the neck 18 is facilitated in particular by the presence of the chamfer 25 which provides a self centering effect of the ribs 72 as soon as their lower end edges 73 come into contact with the chamfer 25.
Afin de faciliter la mise en regard initiale des ergots de verrouillage 68 avec les tronçons supérieurs 30 des gorges de verrouillage 26, il est possible de prévoir des moyens visuels non représentés de repérage de la position angulaire initiale de la bague 16 par rapport au goulot 18 et/ou par rapport au corps inférieur 12. Selon le détail de réalisation illustré à la figure 6, on voit que l'extrémité angulaire borgne 34 de chaque tronçon horizontal 30 présente un profil particulier arrondi circulaire globalement complémentaire du profil extérieur cylindrique convexe du doigt de verrouillage 68. Le diamètre interne de cette extrémité borgne arrondie 34 est légèrement décalé axialement vers le haut par rapport au bord supérieur 31 sensiblement horizontal du tronçon 30 de manière que, sous l'effet de l'élasticité résultant de la compression axiale de la collerette radiale 42 la tétine 14, le doigt de verrouillage correspondant 68 vienne, en fin de course angulaire, s'y loger de manière à procurer à l'utilisateur une sensation tactile de fin de course et à procurer un effet de blocage supplémentaire évitant le déverrouillage accidentel. Le profil arrondi procure de plus un effet de rampe qui facilite le déverrouillage angulaire et le démontage de la bague.In order to facilitate the initial facing of the locking lugs 68 with the upper portions 30 of the locking grooves 26, it is possible to provide unrepresented visual means for marking the initial angular position of the ring 16 with respect to the neck 18. and / or with respect to the lower body 12. According to the embodiment detail illustrated in FIG. 6, it can be seen that the blind angular end 34 of each horizontal section 30 has a particular circular rounded profile which is generally complementary to the convex cylindrical outer profile of the finger The internal diameter of this rounded blind end 34 is slightly offset axially upwards with respect to the substantially horizontal upper edge 31 of the section 30 so that, under the effect of the elasticity resulting from the axial compression. the teat 14, the corresponding locking finger 68 comes, at the end of the angular stroke, to be housed therein so as to provide the user with a tactile sensation of end of stroke and to provide an additional blocking effect. avoiding accidental unlocking. The rounded profile also provides a ramp effect that facilitates the angular unlocking and disassembly of the ring.
Comme on peut le voir à la même figure, l'extrémité supérieure débouchante 29 du tronçon vertical 28 présente un profil évasé en « V » pour faciliter l'introduction axiale de haut en bas d'un ergot de verrouillage correspondant 68.As can be seen in the same figure, the upper outlet end 29 of the vertical section 28 has a flared profile "V" to facilitate the axial introduction from top to bottom of a corresponding locking pin 68.
Bien entendu l'invention n'est pas limitée au mode de réalisation préféré qui vient d'être décrit et de nombreuses variantes des moyens de verrouillage à baïonnette et des moyens de centrage sont possibles sans sortir du cadre de l'invention.Naturally, the invention is not limited to the preferred embodiment which has just been described and many variants of the bayonet locking means and centering means are possible without departing from the scope of the invention.
Selon une inversion mécanique simple entrant dans le cadre de la présente invention, il est par exemple possible de former les doigts de verrouillage en saillie radialement vers l'extérieur sur le goulot 18 et de former de manière complémentaire des gorges de verrouillage dans la paroi latérale intérieure concave de la jupe latérale de la bague de verrouillage.According to a simple mechanical inversion within the scope of the present invention, it is for example possible to form the locking fingers projecting radially outwards on the neck 18 and to form complementary locking grooves in the side wall. Concave interior of the side skirt of the locking ring.
Selon une autre inversion mécanique simple entrant dans le cadre de la présente invention, il est possible de former les nervures de centrage en relief vers l'extérieur sur la paroi latérale extérieure convexe du goulot 18 de manière qu'ils coopèrent avec une portion en vis-à-vis de la paroi latérale intérieure concave de la jupe latérale de la bague de verrouillage.According to another simple mechanical inversion within the scope of the present invention, it is possible to form the raised centering ribs outwardly on the convex outer lateral wall of the neck 18 so that they cooperate with a screwed portion. vis-à-vis the concave inner side wall of the side skirt of the locking ring.
L'invention n'est pas non plus limitée aux nombres d'ergots de verrouillage, de gorges de verrouillage et de nervures de centrage qui viennent d'être décrits.The invention is also not limited to the numbers of locking lugs, locking grooves and centering ribs which have just been described.
Le corps et la bague de verrouillage peuvent être réalisés, notamment par moulage, dans tout matériau convenable et par exemple dans des matières plastiques thermoplastiques et/ou thermodurcissables.The body and the locking ring may be made, in particular by molding, in any suitable material and by example in thermoplastic and / or thermosetting plastics.
Lorsque le corps, la bague, voire le capuchon de protection de la tétine qui s'adapte sur la bague, présentent une section qui n'est pas de révolution autour de l'axe du biberon , par exemple triangulaire, l'invention est particulièrement adaptée et simple d'utilisation car les formes extérieures triangulaires facilitent le repérage de la position angulaire de la bague par rapport au corps. On décrira maintenant une bague de fixation 16 de profil triangulaire qui est illustrée à la figure 8 et qui comporte trois ergots de verrouillage répartis angulairement de manière régulière.When the body, the ring, or even the protective cap of the pacifier that fits on the ring, have a section that is not revolution about the axis of the bottle, for example triangular, the invention is particularly adapted and easy to use because the triangular outer shapes facilitate the identification of the angular position of the ring relative to the body. We will now describe a fastener ring 16 of triangular profile which is illustrated in Figure 8 and which has three locking pins angularly distributed in a regular manner.
Comme illustré à cette figure 8, la jupe latérale 52 est divisée en trois tronçons angulaires régulièrement espacés et qui sont entourés par une paroi latérale continue 80 de profil triangulaire et de préhension de la bague 16.As illustrated in this FIG. 8, the lateral skirt 52 is divided into three regularly spaced angular portions which are surrounded by a continuous lateral wall 80 of triangular profile and of gripping of the ring 16.
La jupe latérale 52 est d'épaisseur sensiblement constante, et sensiblement égale à l'épaisseur de la bride supérieure 50. La jupe 52 présente ici un profil constant sur toute sa hauteur axiale, c'est-à-dire qu'elle ne comporte que le "deuxième" tronçon inférieur 62 qui est délimité radialement par une face latérale intérieure concave 64, et verticalement vers le bas par un bord inférieur d'extrémité libre 66. La bague 16 comporte ici trois ergots de verrouillage 68 régulièrement répartis angulairement à 120 degrés, chacun au centre d'un tronçon associé de la jupe 52.The lateral skirt 52 is of substantially constant thickness, and substantially equal to the thickness of the upper flange 50. The skirt 52 here has a constant profile over its entire axial height, that is to say that it does not comprise that the "second" lower section 62 which is delimited radially by a concave inner side face 64, and vertically downwards by a lower free end edge 66. The ring 16 here comprises three locking lugs 68 regularly angularly distributed at 120 degrees, each in the center of an associated section of the skirt 52.
De manière complémentaire, le goulot complémentaireIn a complementary way, the complementary bottleneck
(non représenté) du corps du biberon comporte trois gorges en « L » .(not shown) the body of the bottle has three "L" grooves.
Chaque ergot de verrouillage 68 est un ergot de forme générale polyédrique et d'orientation radiale et ses dimensions externes sont légèrement inférieures à la largeur de la gorge complémentaire 26 de façon qu'il puisse y être introduit et y circuler. Chaque ergot 68 est chanfreiné vers le bas.Each locking pin 68 is a pin of generally polyhedral shape and radially oriented and its external dimensions are slightly smaller than the width of the throat complementary 26 so that it can be introduced and circulate there. Each lug 68 is chamfered downwards.
Chaque ergot de verrouillage 68 s'étend radialement vers l'intérieur depuis la face latérale concave 64 et il est agencé axialement légèrement au-dessus du bord inférieur 66.Each locking pin 68 extends radially inwardly from the concave side face 64 and is arranged axially slightly above the lower edge 66.
Sur la plus grande partie de sa hauteur axiale, la face latérale intérieure concave 64 du tronçon inférieur 62 de la jupe latérale 52 de la bague 16 comporte une série de nervures de centrage 72, qui sont ici au nombre de six réparties angulairement de manière régulière.Over most of its axial height, the concave inner side face 64 of the lower section 62 of the lateral skirt 52 of the ring 16 comprises a series of centering ribs 72, which are here six in number distributed angularly in a regular manner. .
Chaque nervure de centrage 72 est ici un « godron » qui est réalisé venue de matière par moulage et qui est formé en relief, radialement vers l'intérieur, dans la face concave 64.Each centering rib 72 is here a "godron" which is produced integrally by molding and which is formed in relief, radially inwards, in the concave face 64.
Chaque nervure de centrage 72 se présente sous la forme d'une barrette verticale de profil arrondi convexe.Each centering rib 72 is in the form of a vertical bar of convex rounded profile.
Chaque tronçon de la jupe latérale 52 comporte, de part et d'autre de l'ergot 68, une nervure 72, soit une paire de nervures 72 associée à chaque ergot 68.Each section of the lateral skirt 52 comprises, on either side of the lug 68, a rib 72, or a pair of ribs 72 associated with each lug 68.
La face inférieure 56 de la bride 50 comporte ici, adjacente au bord du trou central 54, une nervure circulaire 76 de section en demi-cercle qui est interrompue en trois tronçons angulaires.The lower face 56 of the flange 50 here comprises, adjacent to the edge of the central hole 54, a circular rib 76 of semicircular section which is interrupted in three angular portions.
Cette nervure 76 en relief participe à l'étanchéité du biberon et, en combinaison avec d'autres moyens prévus sur la tétine 14 (tels que des entrées d'air), participe à la régulation de l'entrée de l'air dans le biberon pour compenser la dépression due à la succion par le bébé.This rib 76 in relief contributes to the tightness of the bottle and, in combination with other means provided on the nipple 14 (such as air inlets), participates in the regulation of the entry of air into the bottle to compensate for depression due to suction by the baby.
Cette conception permet d'utiliser une tétine dont la collerette annulaire radiale inférieure 40, aussi appelée plateau de la tétine, est plate. Lors du serrage, la nervure 76 exerce la pression sur la face supérieure 44 de la collerette 40 en autorisant un mouvement de celle-ci du haut vers le bas. De ce fait, la lèvre située sur la face 44 va se "rapprocher" de l'intérieur du goulot. La face intérieure 56 de la bride 50, comporte encore, radialement vers l'extérieur par rapport à la nervure 76, une autre nervure circulaire 78 qui contribue à la résistance à l'arrachement de la tétine qui est bloquée entre la bride 50 de la bague 52 et le bord supérieur d'extrémité libre 20 du goulot 18. This design makes it possible to use a pacifier whose lower radial annular flange 40, also called the pacifier plate, is flat. When tightening, the rib 76 exerts pressure on the upper face 44 of the collar 40 allowing movement thereof from top to bottom. As a result, the lip on the face 44 will "get closer" to the inside of the neck. The inner face 56 of the flange 50, further comprises, radially outwardly with respect to the rib 76, another circular rib 78 which contributes to the tear resistance of the nipple which is clamped between the flange 50 of the ring 52 and the upper free end edge 20 of the neck 18.
