mode de realisation de l' invention. embodiment of the invention.

Le biberon de la figure 1 comprend un corps 2, represente seulement partiellement, qui possede un col The bottle of Figure 1 comprises a body 2, shown only partially, which has a neck

superieur 4 muni d'un filetage 6.upper 4 provided with a thread 6.

Ce biberon est en outre pourvu d'une tetine 8, possedant un embout aminci lo, une robe intermediaire 12, This bottle is also provided with a nipple 8, having a thinned end, an intermediate dress 12,

ainsi qu'une collerette terminale 14. as well as a terminal flange 14.

Il est egalement prevu une bague 16, comprenant un fut taraude 18, apte a cooperer avec le filetage 6, ainsi qutun rebord superieur 20, creuse d'une ouverture centrale du There is also provided a ring 16, comprising a barrel 18, capable of cooperating with the thread 6, as well as an upper rim 20, hollow with a central opening of the

lo passage de la tetine.lo passage of the pacifier.

Il est a noter que le rebord 20 est pourvu, sur sa It should be noted that the rim 20 is provided, on its

face en regard de la tetine, dinne nervure peripherique 22. opposite the nipple, dinne peripheral rib 22.

Cette derriere prend appui contre la tetine 8, en service, This back rests against the nipple 8, in service,

au voisinage d'un epaulement 24 de cette derriere. in the vicinity of a shoulder 24 of this behind.

Le biberon comporte de plus un organe 26, qui forme clapet anti-retour et permet, de facon classique, The bottle also comprises a member 26, which forms a non-return valve and allows, in a conventional manner,

d'empecher le retour du liquide de la tetine vers le corps. prevent the return of the liquid from the pacifier to the body.

Ce clapet 26 comprend une plage principale 28, dont la face inferieure prend appui, en service, contre l'extremite superieure du col 4. Une jupe 30 fait par ailleurs saillie, This valve 26 comprises a main track 28, the lower face of which bears, in service, against the upper end of the neck 4. A skirt 30 also projects,

a partir de la plage 28, dans le volume interieur du col 4. from range 28, in the interior volume of the neck 4.

I1 est egalement prevu un organe mobile 32, qui est monte en rotation autour d'un axe A horizontal, a savoir parallele au plan principal de la plage 28. Cet organe mobile 32 est ainsi articule lateralement, de sorte qutil est a meme de liberer une ouverture suffisamment importante pour eviter tout encrassement, particulierement dans le cas I1 is also provided a movable member 32, which is rotatably mounted about a horizontal axis A, namely parallel to the main plane of the range 28. This movable member 32 is thus articulated laterally, so that it is able to release an opening large enough to avoid fouling, especially in the case

ou un liquide epais est administre au nourrisson. or a thick liquid is administered to the infant.

De facon avantageuse, l'organe mobile 32 peut etre monte, de facon amovible, sur la plage principale 28, par exemple par encliquetage elastique. Ceci garantit alors une Advantageously, the movable member 32 can be mounted, removably, on the main track 28, for example by elastic snap-fastening. This then guarantees a

facilite de nettoyage appreciable.easy cleaning appreciable.

Selon une autre caracteristique avantageuse, cet organe mobile 32 peut etre realise en un silicone alimentaire. Dans cet esprit, un tel organe est inalterable, hygienique, resiste a toute temperature utile a sa sterilisation et ne presente aucun danger pour le nourrisson. Comme le montrent plus precisement les figures 2 et 3, la peripherie exterieure de la plage 28 est chanfreinee, au niveau de sa face superieure. Ceci conduit done a la formation d'une portion conique d'extremite 34, qui According to another advantageous characteristic, this movable member 32 can be produced from a food grade silicone. In this spirit, such an organ is unalterable, hygienic, resists any temperature useful for its sterilization and presents no danger to the infant. As shown more precisely in Figures 2 and 3, the outer periphery of the track 28 is chamfered, at its upper face. This therefore leads to the formation of a conical end portion 34, which

s'amincit vers l'exterieur.thins outwards.

Cette extremite 34 coopere par ailleurs avec une extremite evasee 36 de la tetine 8. Les extremites precitees 34 et 36 presentent ainsi, en coupe transversale, This end 34 also cooperates with a flared end 36 of the nipple 8. The aforementioned ends 34 and 36 thus have, in cross section,

des profile mutuels conjugues.mutual mutual profiles.

L'extremite superieure du col 6 est creusee d'une echancrure radiale, ou canal 38, qui presente une section relativement faible, par exemple de l'ordre de 1 mm. Les parois de ce canal 38 delimitent, avec la face en regard du clapet 26, une ouverture mettant en communication, avec The upper end of the neck 6 is hollowed out with a radial notch, or channel 38, which has a relatively small section, for example of the order of 1 mm. The walls of this channel 38 delimit, with the opposite face of the valve 26, an opening bringing into communication, with

l'air ambient, le volume interieur V du corps 2. ambient air, the interior volume V of the body 2.

Dans un souci de clarte, la reference 38 sera egalement affectee a cette ouverture. I1 convient de noter que cette derriere forme un moyen de passage d'air en direction du volume interieur V. Dans la position de la figure 2, la bague 16 exerce seulement une pression moderee sur la tetine 8, de sorte que cette derriere n'est sensiblement pas deformee, par rapport a sa position de repos. La tetine 8 libere ainsi, For the sake of clarity, reference 38 will also be assigned to this opening. It should be noted that the latter forms an air passage means in the direction of the interior volume V. In the position in FIG. 2, the ring 16 exerts only moderate pressure on the nipple 8, so that the latter does not is not appreciably deformed, compared to its rest position. The pacifier 8 thus releases,

de maniere pratiquement totale, l'ouverture precitee 38. practically total, the aforementioned opening 38.

Ceci autorise alors un passage d'air important en direction du volume interieur V. De la sorte, le debit administre au nourrisson, materialise par la fleche F. est This then allows a significant passage of air towards the interior volume V. In this way, the flow rate administered to the infant, materialized by the arrow F. is

relativement eleve.relatively high.

Il convient de noter que, sur cette figure 2, le clapet 26 assume sa fonction classique, puisqu'il empeche le retour du liquide, admis dans la tetine 8, en direction du volume interieur V. Si l'on desire diminuer le debit de liquide administre au nourrisson, il s'agit de visser la bague 16. La tetine 8 se trouve alors comprimee entre la nervure 22 de la bague It should be noted that, in this FIG. 2, the valve 26 assumes its conventional function, since it prevents the return of the liquid, admitted into the nipple 8, in the direction of the interior volume V. If it is desired to reduce the flow rate of liquid administered to the infant, it is to screw the ring 16. The nipple 8 is then compressed between the rib 22 of the ring

16 et liextremite conique 34 du clapet 26. 16 and conical end 34 of the valve 26.

Ceci induit done une deformation de la tetine, par fluage. Comme le montre la figure 3, une fois la bague 16 vissee, la tetine possede desormais un bourrelet This therefore induces a deformation of the teat, by creep. As shown in Figure 3, once the ring 16 screwed, the nipple now has a bead

peripherique 40, prolongeant son extremite evasee 36. peripheral 40, extending its flared end 36.

Un tel bourrelet 40 recouvre ainsi, de facon partielle, l'ouverture 38. On concoit que le debit d' air susceptible de s'ecouler vers le volume interieur V materialise par la fleche f, est sensiblement inferieur a celui de la figure 2. Cette diminution du debit du passage d' air s'accompagne, par consequent, d'une diminution correspondante du debit de liquide administre au nourrisson. Par ailleurs, si lton visse davantage la bague 16, cette derriere contribue a deformer la tetine 8, jusqu'a ce Such a bead 40 thus partially covers the opening 38. It can be seen that the air flow rate likely to flow towards the interior volume V materialized by the arrow f, is substantially lower than that of FIG. 2. This decrease in air flow rate is therefore accompanied by a corresponding decrease in the liquid flow rate administered to the infant. Furthermore, if lton further screws the ring 16, the latter contributes to deforming the nipple 8, until

que cette derriere obture entierement l'ouverture 38. that this behind completely closes the opening 38.

Dans ce cas, l'air ne peut plus stecouler en direction du volume interieur V, de sorte que le liquide ne peut plus stechapper du biberon. Ce dernier se trouve alors aisement In this case, the air can no longer flow in the direction of the interior volume V, so that the liquid can no longer escape from the bottle. The latter is then easily

transportable, sans risque de salissures. transportable, without risk of soiling.

En revanche, si l'on desire a nouveau augmenter le debit de liquide administre au nourrisson, il s'agit de devisser la bague 16. De la sorte, la tetine 8 revient, par elasticite, dans sa position initiale de la figure 2, On the other hand, if it is again desired to increase the flow rate of liquid administered to the infant, it is a question of unscrewing the ring 16. In this way, the nipple 8 returns, by elasticity, to its initial position in FIG. 2,

autorisant un debit plus eleve.authorizing a higher debit.

I1 convient de remarquer que la forme conique de l'extremite 34 du clapet 26 est avantageuse. En effet, elle constitue une amorce en vue de la deformation de la tetine, It should be noted that the conical shape of the end 34 of the valve 26 is advantageous. Indeed, it constitutes a primer for the deformation of the teat,

par fluage.by creep.

Comme cela ressort de la precedente description, As is clear from the previous description,

l'utilisatrice est a meme de faire varier le debit de liquide administre au nourrisson, de facon simple et progressive. En effet, un tel debit est directement lie au degre du vissage de la bague 16. La figure 4 illustre une variante de realisation du biberon d'allaitement conforme a ['invention. Sur cette figure, les elements mecaniques analogues a ceux des figures 1 a 3 y vent affectes des memes numeros de the user is able to vary the flow rate of liquid administered to the infant, in a simple and progressive manner. Indeed, such a flow rate is directly linked to the degree of screwing of the ring 16. FIG. 4 illustrates an alternative embodiment of the nursing bottle according to the invention. In this figure, the mechanical elements similar to those of FIGS. 1 to 3 are assigned the same numbers of

reference, augmentes de 100.reference, increased by 100.

Le clapet 126, illustre sur cette figure 4, comprend, outre la plage 128 et la jupe 130, une saillie centrale 131, sur laquelle est monte l'organe mobile 132. Une telle saillie 131 est apte a etre fixce, par emboltement, The valve 126, illustrated in this FIG. 4, comprises, in addition to the pad 128 and the skirt 130, a central projection 131, on which is mounted the movable member 132. Such a projection 131 is suitable for being fixed, by embolism,

contre la paroi interieure de la robe 112 de la tetine 108. against the interior wall of the dress 112 of the pacifier 108.

Cette fixation amovible du clapet 126 et de la tetine 108 est avantageuse, en termes de facilite d'emploi. En effet, l'utilisatrice est a meme d' assuettir tout d' abord mutuellement ces deux elements, avant de monter ltensemble This removable attachment of the valve 126 and the nipple 108 is advantageous in terms of ease of use. Indeed, the user is able to first mutually subdue these two elements, before mounting the assembly

ainsi forme sur le corps du biberon. thus forms on the body of the bottle.

L' invention n'est pas limitee aux exemples decrits et representes. En effet, les moyens de passage d' air en direction du volume interieur du biberon peuvent etre differents de ceux The invention is not limited to the examples described and shown. Indeed, the means of air passage towards the interior volume of the bottle can be different from those

illustres.illustrious.

Ainsi, ces moyens de passage peuvent etre delimites par le col et par la tetine, le clapet anti-retour etant alors absent. Dans cet esprit, la tetine obture progressivement, par deformation du fait de son fluage, un canal menage sur ce col, analogue a celui 28 des figures 1 a 3. On peut egalement prevoir de pratiquer, a la peripherie exterieure du clapet, une lumiere mettant en communication le volume interieur du biberon avec l' air ambient. Dans cette optique, la tetine est a meme de recouvrir partiellement une telle lumiere, par deformation Thus, these passage means can be delimited by the neck and by the nipple, the non-return valve then being absent. In this spirit, the nipple gradually closes, by deformation due to its creep, a channel formed on this neck, similar to that 28 of Figures 1 to 3. It can also be planned to practice, at the outer periphery of the valve, a light connecting the interior volume of the bottle to the ambient air. In this context, the nipple is able to partially cover such a light, by deformation

sous lteffet de son fluage.under the effect of its creep.

De plus, il est envisageable de prevoir, sur le biberon, des reperes permettant de visualiser les In addition, it is possible to provide markers on the bottle for viewing the

differents debits qui vent permis par le biberon. different flow rates which are allowed by the bottle.

L'invention permet de realiser les objectifs The invention makes it possible to achieve the objectives

precedemment mentionnes.previously mentioned.

En effet, grace au biberon de ['invention, l'utilisatrice maltrise, de facon simple et precise, le Indeed, thanks to the bottle of the invention, the user controls, in a simple and precise way, the

debit de liquide effectivement administre au nourrisson. liquid flow actually administered to the infant.

A cet egard, il est possible d' obliger le nourrisson a effectuer la tetee du biberon dans un temps donne. De la sorte, l' invention assure une education du nourrisson en ce qui concerne son alimentation, puisque ce dernier sera incite a pratiquer un temps de tetee similaire a celui In this regard, it is possible to force the infant to breastfeed the bottle within a given time. In this way, the invention provides an education for the infant with regard to his feeding, since the latter will be encouraged to practice a feeding time similar to that

observe lors d'une tetee << ideale >>, au sein maternel. observed during an "ideal" breastfeeding, in the womb.

Ceci induit de nombreuses consequences, aussi bien This has many consequences, as well

psychiques ou physiques.psychic or physical.

Le nourrisson est satisfait de sa tetee, queue que The infant is satisfied with his suckling, tail that

soit sa nature, goulu, normal ou paresseux. either his nature, greedy, normal or lazy.

I1 ne regurgite plus et manifeste des r8ts similaires It no longer regurgitates and manifests similar r8ts

a ceux observes lors d'une alimentation au sein maternel. to those observed during breastfeeding.

Le nourrisson ne pleure pas, du fait d'un eventuel enervement provoque par la remontee du liquide dans le corps du biberon, grace a la presence du clapet anti retour. De plus, le nourrisson n'est pas sujet a un enervement qui serait relatif a un comportement defectueux du biberon, tels que des regurgitations par etouffement, loreque le The infant does not cry, due to a possible nervousness caused by the ascent of the liquid in the body of the bottle, thanks to the presence of the non-return valve. In addition, the infant is not subject to nervousness which is related to defective behavior of the bottle, such as regurgitation by choking, when

liquide est absorbe d'une maniere intempestive. liquid is absorbed in an untimely manner.

Enfin, grace a ['invention, le probleme du percage de lextremite amincie de la tetine, faisant ['objet de nombreuses recherches, est rendu secondaire. En effet, il est desormais possible de pratiquer une simple fente jointive, ce qui avantageux dans la mesure ou tout Finally, thanks to the invention, the problem of piercing the thinned end of the nipple, the subject of much research, is made secondary. Indeed, it is now possible to practice a simple contiguous slit, which is advantageous insofar as any

ecoulement intempestif hors du biberon est evite. accidental spillage out of the bottle is avoided.
