Abstract

The valve is constituted by a disc 8 provided with a lateral heel piece 7 which is hinged on the usual transverse wall 1, so that the boss 10 can close the opening 11 of the latter. The abutting of the heel piece 7 against the upper face of the wall 1 limits the opening of the valve and allows its return to the closed position under the effect of a pressure.

Description

La présente invention a trait aux dispositifs de biberons utilises pour l'allaitement des nourrissons ou du bétail. The present invention relates to baby bottle devices used for breastfeeding infants or livestock.

On connaît, notamment par le brevet français N 1.444.949 déposé au nom de Joseph GRASSET le 26 Mai 1965 pour "Perfectionnesents aux dispositifs de biberons", des biberons d'allaitement pourvus, au niveau de l'ouverture sur laquelle vient s'adapter la tetine déformable usuelle, d'une cloison transversale dans laquelle est monté un clapet anti-retour normalement maintenu en position ouverte pour permettre le passage du lait ou autre liquide, du Excipient à l'espace intérieur de la tétine, tout en entant susceptible de se refermez lorsque cette dernière est comprimée et que le liquide tend à remonter dans ledit récipient
Cette disposition s'est revolée particulièrement avantageuse par le fait que le seul serrage de la tetine entre les levres ou gencives du nourrisson suffit pour obliger le lait d > sortir, même en l'absence de toute succion.
We know, in particular by the French patent N 1,444,949 filed in the name of Joseph GRASSET on May 26, 1965 for "Perfectionnesents aux devices de biberons", breastfeeding bottles provided, at the opening on which fits the usual deformable teat, a transverse partition in which is mounted a non-return valve normally maintained in the open position to allow the passage of milk or other liquid, from the excipient to the interior space of the teat, while being likely to close when the latter is compressed and the liquid tends to rise in said container
This arrangement is particularly advantageous in that the only tightening of the pacifier between the baby's lips or gums is enough to force the milk to come out, even in the absence of any suction.

flans les constructions connues, le clapet comprend un disque plat solidaire d'une tige axiale qui est engagea a coulissement dans une perforation centrale de la cloison transversale, le coulissement étant limite par une tete épanouie prévue a l'extrémité libre de ladite tige. In known constructions, the valve comprises a flat disc secured to an axial rod which is slidably engaged in a central perforation of the transverse partition, the sliding being limited by a open head provided at the free end of said rod.

Le disque précite est agence pour venir s'appliquer contre une serie de lumières pratiquées concentrîquement a la perforation centrale de la cloison, en s opposant alors au passage du liquide.The aforementioned disc is arranged to come to bear against a series of lights practiced mainly at the central perforation of the partition, thus opposing the passage of the liquid.

l'experience a démontre que les lumières menagees dans la cloison s'obturaient fréquemment, notamment lorsque le biberon etait rempli d'une bouillie ou autre aliment liquide contenant en suspension des particules solides ou pâteuses. On a pu par ailleurs observer que le clapet coulissant genait le nettoyage de 11 ensemble formé par la cloison et ledit clapet. experience has shown that the lights in the partition were often blocked, especially when the bottle was filled with a mixture or other liquid food containing suspended solid or pasty particles. It has also been observed that the sliding valve obstructs the cleaning of the assembly formed by the partition and said valve.

C1 est à ces inconvenients qu'entend principalement remédier la présente invention, laquelle consiste essentiellement à constituer le clapet anti-retour par un disque pourvu d'un talon latéral convenablement articulé sur la cloison transversale destinée à le supporter, de façon a obturer une large ouverture pratiquée dans celle-ci.  C1 is to these disadvantages which the present invention mainly intends to remedy, which consists essentially in constituting the non-return valve by a disc provided with a lateral heel suitably articulated on the transverse partition intended to support it, so as to close off a large opening in it.

Conformément à un mode de mise en oeuvre préféré de la disposition qui précède, la face du disque articule qui est tournée en direction de l'ouverture ménagée dans la cloison transversale comporte un bossage agencé pour s'engager à l'intérieur de l'ouverture précitez, la paroi de cette dernière et la paroi latérale du bossage étant établies à un profil tronconique en vue de l'obtention d'une bonne étanchéite. A l'opposé de ce bossage, le disque ou clapet est pourvu d'une queue axiale qui facilite sa préhension et celle de la cloison qui le supporte. In accordance with a preferred embodiment of the above arrangement, the face of the articulated disc which is turned towards the opening made in the transverse partition has a boss arranged to engage inside the opening above, the wall of the latter and the side wall of the boss being established in a frustoconical profile in order to obtain a good seal. Opposite this boss, the disc or valve is provided with an axial tail which facilitates its gripping and that of the partition which supports it.

Le talon latéral présente un renflement cylindrique orienté transversalement et dont les extrémités depassantes sont engagées et retenues par encliquetage à l'intérieur de parties terminales fourchues prevues en bout de doux pattes verticales solidaires de la cloison transversale.The lateral heel has a transversely oriented cylindrical bulge, the protruding ends of which are engaged and retained by snap-fastening inside forked end portions provided at the end of soft vertical tabs integral with the transverse partition.

On observera que le talon latéral se prolonge au delà du renflement transversal ou pivot afin de venir porter par son extrmite libre contre la face supérieure de la cloison, en limitant ainsi le déplacement angulaire du clapet à l'ouverture. It will be observed that the lateral heel extends beyond the transverse or pivot bulge in order to come to bear by its free end against the upper face of the partition, thereby limiting the angular displacement of the valve at the opening.

Le dessin annexe, donné à titre d'exemples permettra de mieux comprendre l'invention, les caractéristiques qu'elle pro sente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une vue en plan illustrant l'agencement général d'un clapet anti-retour pour biberon, établi conformément a la présente invention.
The annexed drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it offers and the advantages which it is likely to provide.
Fig. 1 is a plan view illustrating the general arrangement of a non-return valve for a bottle, established in accordance with the present invention.

Fig. 2 est la coupe diamétrale correspondante. Fig. 2 is the corresponding diametral section.

Fig. 3 est une coupe de détail a échelle agrandie montrant le clapet a la position ouverte. Fig. 3 is a detail section on an enlarged scale showing the valve in the open position.

Sur ce dessin, la référence 1 de signe la cloison transversale usuellement dispose contre le bord terminal d'un biberon 2, la retenue en place de cette cloison 1 étant assure par la base de la tétine déformable 3 elle-mEme immobilises par la bague vissas 4. In this drawing, the reference 1 of sign the transverse partition usually has against the terminal edge of a bottle 2, the retention in place of this partition 1 being ensured by the base of the deformable teat 3 itself immobilized by the screw ring 4.

La face superieure de la cloison 1 est solidaire de deux pattes verticales 5 dont le sommet on forme de fourche est conforme de façon à recevoir, moyennant doformation elastique momontanés, et à retenir a pivotement les extrémités débordantes d'un renflement 6 qui barre transversalement le talon latéral 7 d'un disque circulaire 8. Ce dernier, pourvu d'une queue axiale 9 tourne vers le haut, présente sur sa face inférieure un bossage 10 a paroi extérieure tronconique, propre à venir coopérer de manière étanche avec la paroi, également tronconique, d'une large ouverture 11 ménagée au centre de la cloison 1. The upper face of the partition 1 is integral with two vertical legs 5, the top of which forms a fork conforms so as to receive, by means of elastic momontane doformation, and to pivotally retain the projecting ends of a bulge 6 which crosswise crosses the lateral heel 7 of a circular disc 8. The latter, provided with an axial tail 9 rotates upwards, has on its lower face a boss 10 with a frustoconical outer wall, suitable for coming to cooperate sealingly with the wall, also frustoconical, with a wide opening 11 formed in the center of the partition 1.

Lorsque le biberon 2 est posé verticalement sur une table, le disque articulé ou clapet 8 est à la position de fermeture illustrée en fig. 1 et 2, pour laquelle le bossage 10 engagé dans l'ouverture 11 obture cette dernière. Par contre dès que ce biberon est orienté obliquement vers le bas pour être introduit dans la bouche d'un nourrisson, le clapet précité bascule par gravité moyennant pivotement du ronflement 6 dans les pattes 5 ; comme le talon 7 se prolonge au-deld de ce renflement 6, son extrémité vient porter-contre la face supérieure de la cloison 1 à la manière illustrée on fig. 30 On conçoit que cette limitation du déplacement du clapet 8 permet a ce ce dernier de revenir à la position fermée lorsque le serrage de la tétine entre les lèvres ou gencives du nourrisson provoque l'apparition d'une surpression a l'intérieur de ladite tétine, de la même maniere que dans le dispositif de clapet suivant la brevet N 1.444.949 cité au début des présentes. When the bottle 2 is placed vertically on a table, the articulated disc or valve 8 is in the closed position illustrated in FIG. 1 and 2, for which the boss 10 engaged in the opening 11 closes the latter. By cons as soon as this bottle is oriented obliquely downward to be introduced into the mouth of an infant, the aforementioned valve switches by gravity by pivoting snoring 6 in the legs 5; as the heel 7 extends beyond this bulge 6, its end comes to bear against the upper face of the partition 1 in the manner illustrated in FIG. 30 It is understood that this limitation of the movement of the valve 8 allows the latter to return to the closed position when the tightening of the pacifier between the lips or gums of the infant causes the appearance of an overpressure inside said pacifier , in the same way as in the valve device according to patent N 1,444,949 cited at the beginning of the present document.

le relativement large diamètre de l'ouverture 11 évite radicalement tout risque d'obturation intempestive. les opérations de nettoyage sont aisées, le clapet étant susceptible d'etre facilement démonté lorsque nécessaire. On remarquera que la tige supérieure 9 permet la manipulation du clapet et de l'ensemble formé par celui- ci et la cloison, cette manipulation pouvant être effectuée soit manuellement, soit A l'aide d'une pince ou autre outil du genre de celui schématisé en 12 en fig. 2. the relatively large diameter of the opening 11 radically avoids any risk of inadvertent blockage. cleaning operations are easy, the valve being able to be easily disassembled when necessary. It will be noted that the upper rod 9 allows the manipulation of the valve and of the assembly formed by the latter and the partition, this manipulation being able to be carried out either manually, or using pliers or other tool of the kind of that schematically at 12 in fig. 2.

Il doit d'ailleurs Entre entendu que la description qui précoce n'a été donnée qu'd titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas on remplaçant les détails d'exécution décrits par tous autres équivalents.  It should moreover be understood that the description which precedes has been given only by way of example and that it in no way limits the field of the invention from which one would not depart from, replacing the execution details described by all other equivalents.
