The spring is embedded in the wall (7) of the nipple. The open end of the teat has a shaped edge (15) for attaching and sealing it to a feeding bottle, and both the body of the teat and the nipple are made in one piece from an elastomer material such as natural latex or a silicone prod. In addn., the body of the teat can be surrounded by a hemispherical cover, also of an elastomer material, which simulates a mother's breast.

Description

La présente invention concerne une tétine pour biberon, ainsi qu'un biberon équipé d'une telle tétine.The present invention relates to a nipple for a baby bottle, as well as a baby bottle equipped with such a nipple.

La forme des tétines actuelles et le matériau utilisé pour leur fabrication, généralement un élastomère, sont tels que ces tétines présentent un coefficient d'écrasement important et un coefficient d'allongement pratiquement nul.The shape of the current teats and the material used for their manufacture, generally an elastomer, are such that these teats have a significant crushing coefficient and a coefficient of elongation practically zero.

Concrètement, une fois la tétine introduite dans sa bouche, le bébé la pousse avec sa langue en direction de la voûte de son palais pour pouvoir exercer une pression qui provoque un écrasement de la tétine avec éjection d'une certaine quantité de liquide qui est déglutie par le bébé.Concretely, once the pacifier is introduced into his mouth, the baby pushes it with his tongue towards the arch of his palate to be able to exert a pressure which causes a crushing of the pacifier with ejection of a certain amount of liquid which is swallowed by the baby.

Ce mécanisme de prise de nourriture a notamment pour conséquences :

  • une absorption concomitante d'air qui conduit à des rots et à des problèmes gastro-intestinaux bien connus des pédiatres, et
  • l'absence de stimulation de la partie distale du palais mou ne permet pas que s'établisse la déglutition infantile normale pour le bébé, et conduit alors, au contraire, à un déglutition de type "adulte" considérée comme atypique à cet âge.
The consequences of this food intake mechanism are:
  • concomitant absorption of air which leads to burping and gastrointestinal problems well known to pediatricians, and
  • the absence of stimulation of the distal part of the soft palate does not allow normal infant swallowing to be established, and then leads, on the contrary, to swallowing of the "adult" type considered to be atypical at this age.

En outre, il faut noter également que l'utilisation prolongée des tétines et plus encore des "totottes", conduit à des malformations permanentes des mâchoires et des dents du bébé qui seront ensuite signalées vers l'âge de trois ou quatre ans par les orthodontistes, mais ne se traitent réellement qu'entre neuf et douze ans. Dans certains cas, des troubles phonatoires sont observés par les orthophonistes par suite d'une mauvaise position linguale associée à la tétée au biberon et à un développement disharmonieux de la musculature périorale, ce qui conduit quelquefois à des zézaiements durables. Dans les années récentes, une littérature spécialisée dans ces domaines a d'ailleurs confirmé ces conclusions.In addition, it should also be noted that prolonged use of teats and more so of "totottes", leads to permanent malformations of the baby's jaws and teeth which will then be reported around the age of three or four years by orthodontists , but only really treat each other between the ages of nine and twelve. In some cases, speech disorders are observed by speech-language pathologists as a result of a bad lingual position associated with bottle-feeding and a disharmonious development of the perioral musculature, which sometimes leads to lasting lisping. In recent years, a Literature specializing in these fields has confirmed these conclusions.

D'une manière générale, le but de l'invention est de pallier les inconvénients précités et de concevoir une tétine qui, contrairement à toutes les tétines actuelles mises sur le marché, tient compte des observations scientifiques faites en aval par des orthodontistes ou des phoniâtres, et en amont des résultats des examens dynamiques des mécanismes de prise de nourriture au sein ou au téton de la femme.In general, the object of the invention is to overcome the aforementioned drawbacks and to design a teat which, unlike all current teats placed on the market, takes account of scientific observations made downstream by orthodontists or phoniasters. , and upstream of the results of dynamic examinations of the mechanisms of food intake within or at the breast of a woman.

A cet effet, l'invention propose une tétine pour biberon, comprenant un corps de forme globalement hémisphérique et dont le sommet se prolonge axialement par une partie saillante ayant la forme d'un téton, tétine qui est caractérisée en ce que le téton est équipé de moyens potentiellement dynamiques destinés à permettre par un effet ressort son allongement ou étirement axial suivi d'une rétraction à la longueur initiale d'une part, et un renforcement de sa rigidité pour que la compression radiale soit limitée d'autre part, de manière à ce que la succion ne puisse avoir lieu que par aspiration et non par compression.To this end, the invention provides a bottle nipple, comprising a body of generally hemispherical shape and the top of which is extended axially by a protruding part having the shape of a nipple, nipple which is characterized in that the nipple is equipped potentially dynamic means intended to allow by a spring effect its elongation or axial stretching followed by a retraction to the initial length on the one hand, and a strengthening of its rigidity so that the radial compression is limited on the other hand, so that suction can only take place by suction and not by compression.

Ainsi, une telle tétine a été conçue pour mettre en oeuvre un mécanisme de succion naturelle par aspiration correspondant au mécanisme de prise de nourriture au sein maternel. Dans ces conditions, le bébé peut régler lui-même la quantité de lait ingérée à chaque bolus, ainsi que le rythme de la succion, cette ingestion étant accompagnée d'une prise d'air minimum qui favorise une meilleure digestion.Thus, such a pacifier has been designed to implement a natural suction suction mechanism corresponding to the mechanism of taking food from the mother's breast. Under these conditions, the baby can regulate himself the quantity of milk ingested with each bolus, as well as the rhythm of the suction, this ingestion being accompanied by a minimum air intake which promotes better digestion.

En effet, il a été démontré que la langue du bébé s'enroule autour du téton qui est d'ailleurs peu écrasable et, avec un mouvement arrière d'aspiration, étire l'organe maternel qui double sa longueur. Le sein ainsi stimulé musculairement, éjecte son lait dans l'arrière-gorge du nouveau-né. C'est à ce niveau que se produit alors l'attouchement par la pointe du téton de la zone réflexe située au niveau du palais mou. Cette zone stimulée par la pression conjuguée de l'organe maternel et du lait, met en place un mécanisme de déglutition dit "infantile" qui s'effectue pratiquement sans prise d'air associée.Indeed, it has been shown that the baby's tongue wraps around the nipple which is also not very squeezable and, with a rear suction movement, stretches the maternal organ which doubles its length. The breast thus stimulated by muscles, ejects its milk into the back of the newborn's throat. It is at this level that then produces touching by the tip of the nipple of the reflex zone located at the level of the soft palate. This zone stimulated by the combined pressure of the mother's organ and milk, sets up a so-called "infantile" swallowing mechanism which takes place practically without any associated air intake.

D'une manière générale, au repos la forme et les dimensions du téton selon l'invention sont celles du téton d'un sein maternel.In general, at rest, the shape and dimensions of the nipple according to the invention are those of the nipple of a maternal breast.

Selon un exemple de réalisation, les moyens incorporés dans le téton pour permettre son étirement axial avec retour dans la position initiale, sont constitués par une armature semi-rigide fonctionnant comme un ressort étirable, en forme de boudin et fabriqué par exemple en caoutchouc.According to an exemplary embodiment, the means incorporated in the stud to allow its axial stretching with return to the initial position, are constituted by a semi-rigid reinforcement functioning as a stretchable spring, in the form of a rod and made for example of rubber.

D'une manière générale, le téton est défini par une enveloppe globalement tubulaire fermée à une extrémité qui marque le bout du téton, et l'armature est noyée dans cette enveloppe.Generally, the stud is defined by a generally tubular casing closed at one end which marks the tip of the stud, and the frame is embedded in this casing.

L'extrémité ouverte du corps de la tétine est équipée de moyens permettant d'assembler le corps de la tétine sur le corps d'un biberon d'une manière étanche et amovible.The open end of the teat body is equipped with means for assembling the teat body on the body of a bottle in a sealed and removable manner.

Selon un mode de réalisation de l'invention, le corps de la tétine est entourée d'une calotte simulant le sein maternel et percée d'une ouverture centrale pour le libre passage du téton, la calotte étant destinée à être assemblée au corps du biberon par vissage, par exemple.According to one embodiment of the invention, the body of the teat is surrounded by a cap simulating the maternal breast and pierced with a central opening for the free passage of the nipple, the cap being intended to be assembled to the body of the bottle. by screwing, for example.

La calotte peut être avantageusement recouverte d'une couche d'un élastomère pour simuler la sensation d'une peau humaine, la mère pouvant passer cette couche sur son propre sein pour l'imprégner de son odeur.The cap can advantageously be covered with a layer of an elastomer to simulate the sensation of human skin, the mother being able to pass this layer over her own breast to impregnate it with its odor.

Selon une variante de réalisation de l'invention, la calotte forme le corps de la tétine et peut former également la partie supérieure du corps du biberon.According to an alternative embodiment of the invention, the cap forms the body of the teat and can also form the upper part of the body of the bottle.

L'invention concerne également un biberon dont la forme est adaptée à la tétine ayant les caractéristiques précitées.The invention also relates to a bottle whose shape is adapted to the nipple having the aforementioned characteristics.

Selon un avantage important de l'invention, le téton de la tétine permet de stimuler le mécanisme de succion naturelle du bébé, c'est-à-dire permet l'enroulement de sa langue autour de la tétine et favoriser l'attouchement du palais mou situé à l'arrière et dans le prolongement du palais dur du bébé, par ses possibilités d'étirement.According to an important advantage of the invention, the nipple of the nipple makes it possible to stimulate the baby's natural suction mechanism, that is to say allows the tongue to wrap around the nipple and promote touching of the palate soft located at the back and in the extension of the hard palate of the baby, by its possibilities of stretching.

D'autres avantages, caractéristiques et détails de l'invention ressortiront de la description explicative qui va suivre, faite en référence aux dessins annexés, donnés uniquement à titre d'exemple, et dans lesquels :

  • la figure 1 est une vue en coupe axiale agrandie d'une tétine conforme à l'invention,
  • la figure 2 est une vue en perspective éclatée et partielle d'une tétine et d'un biberon pour illustrer un mode d'assemblage de la tétine sur le corps du biberon, et
  • la figure 3 est une vue en coupe axiale d'une variante de réalisation de la tétine selon l'invention.
Other advantages, characteristics and details of the invention will emerge from the explanatory description which follows, given with reference to the appended drawings, given solely by way of example, and in which:
  • FIG. 1 is an enlarged axial section view of a teat according to the invention,
  • FIG. 2 is an exploded and partial perspective view of a pacifier and a bottle to illustrate a method of assembling the pacifier on the body of the bottle, and
  • Figure 3 is an axial sectional view of an alternative embodiment of the teat according to the invention.

La tétine 1 selon l'invention et telle qu'illustrée à la figure 1 est constituée d'un corps 3 de forme hémisphérique dont le sommet se prolonge axialement par une partie saillante ayant la forme d'un téton 5. La forme et les dimensions données à ce téton 5 sont définies de manière à correspondre globalement à celles du téton du sein maternel pour stimuler le mécanisme de succion naturelle du bébé analogue à celui de la tétée au sein.The nipple 1 according to the invention and as illustrated in FIG. 1 consists of a body 3 of hemispherical shape, the apex of which is extended axially by a projecting part having the shape of a nipple 5. The shape and the dimensions given to this nipple 5 are defined so as to correspond overall to those of the nipple of the maternal breast to stimulate the natural sucking mechanism of the baby analogous to that of breast feeding.

A titre d'exemple, ce téton 5 peut avoir une longueur axiale de 10 à 15 mm environ et un diamètre de l'ordre de 10 à 12 mm, et peut subir un étirement axial d'au moins un facteur 2.By way of example, this stud 5 can have an axial length of approximately 10 to 15 mm and a diameter of the order of 10 to 12 mm, and can undergo an axial stretching of at least a factor of 2.

Le téton 5 est défini par une enveloppe 7 globalement tubulaire dont une extrémité fermée forme le bout du téton et dont l'autre extrémité ouverte est dans le prolongement du sommet du corps 3 de la tétine 1.The nipple 5 is defined by a generally tubular casing 7, one closed end of which forms the tip of the nipple and the other open end of which extends from the top of the body 3 of the nipple 1.

Selon l'invention, le téton 5 de la tétine 1 comprend des moyens 10 qui ont pour fonction de permettre un allongement ou un étirement axial et une rétraction du téton 5 suivant la flèche F1 d'une part, et de rigidifier son enveloppe 7 pour limiter sa compression radiale suivant les flèches F2 d'autre part.According to the invention, the nipple 5 of the nipple 1 comprises means 10 which have the function of allowing an axial elongation or stretching and a retraction of the nipple 5 along the arrow F1 on the one hand, and of stiffening its envelope 7 for limit its radial compression according to arrows F2 on the other hand.

Ces moyens 10 sont constitués par une armature 12 semi-rigide qui est noyée dans l'enveloppe 7 du téton 5. Cette armature 12 est conçue de manière à fonctionner comme un ressort qui donne au téton 5 la possibilité de pouvoir s'étirer sur environ le double de sa longueur avec une force de succion de l'ordre de quelques grammes seulement, et de revenir à sa position initiale.These means 10 are constituted by a semi-rigid frame 12 which is embedded in the casing 7 of the stud 5. This frame 12 is designed so as to function as a spring which gives the stud 5 the possibility of being able to stretch over approximately double its length with a suction force of the order of only a few grams, and return to its original position.

A titre d'exemple, cette armature 12 est constituée par un ressort en forme de boudin, dont le diamètre correspond au diamètre moyen de l'enveloppe 7 du téton 5. Cette armature 12 peut être réalisée en caoutchouc vulcanisé par exemple, en plastique ou en métal.By way of example, this frame 12 is constituted by a coil-shaped spring, the diameter of which corresponds to the average diameter of the casing 7 of the stud 5. This frame 12 can be made of vulcanized rubber for example, plastic or made of metal.

Le bout du téton 5 comporte plusieurs trous 14 qui sont percés au moyen d'un rayon laser par exemple, le nombre et la taille de ces trous 14 pouvant varier en fonction de l'âge du bébé et de sa force de succion.The tip of the stud 5 has several holes 14 which are drilled by means of a laser beam for example, the number and size of these holes 14 may vary depending on the age of the baby and its suction force.

Des moyens de raccordement 15 sont prévus à la partie inférieure du corps 3 de la tétine 1 pour assembler cette dernière de manière étanche et amovible au corps du biberon.Connection means 15 are provided at the lower part of the body 3 of the teat 1 to assemble the latter in a sealed and removable manner to the body of the bottle.

A cet effet, la partie inférieure du corps 3 de la tétine 1 comporte un rebord 17 radialement externe, dont la surface périphérique comporte un filetage 19 destiné à coopérer avec un filetage complémentaire prévu autour d'un orifice du biberon, comme cela sera explicité plus loin.To this end, the lower part of the body 3 of the nipple 1 has a radially outer rim 17, the peripheral surface of which has a thread 19 intended to cooperate with a complementary thread provided around a hole in the bottle, as will be explained more far.

D'une manière générale, le téton 5 et le corps 3 de la tétine 1 forment une seule pièce fabriquée en un matériau élastomère, comme du latex naturel, ou un élastomère de synthèse tel un silicone, par exemple.Generally, the nipple 5 and the body 3 of the nipple 1 form a single piece made of an elastomeric material, such as natural latex, or a synthetic elastomer such as a silicone, for example.

Un biberon 20 adapté à recevoir la tétine 1 précédemment décrite est schématiquement illustré à la figure 2. Ce biberon 20 comporte un corps 22 dont seule la partie supérieure a été partiellement représentée. Ce corps 22 peut être constitué en deux parties supérieure et inférieure qui sont assemblées l'une à l'autre par des moyens appropriés non représentés.A bottle 20 adapted to receive the nipple 1 described above is schematically illustrated in FIG. 2. This bottle 20 comprises a body 22 of which only the upper part has been partially shown. This body 22 can be made up of two upper and lower parts which are assembled to one another by suitable means, not shown.

Le sommet du corps 22 comporte une ouverture centrale 25 dont le pourtour comporte un filetage 27 de forme complémentaire à celle du filetage 19 pour y visser le corps 3 de la tétine 1.The top of the body 22 has a central opening 25, the periphery of which comprises a thread 27 of a shape complementary to that of the thread 19 for screwing the body 3 of the teat 1 into it.

On prévoit également la possibilité de rapporter une calotte 30 autour de la tétine 1 pour simuler le sein maternel. Cette calotte 30 est élargie, de forme hémisphérique et fabriquée par exemple en un matériau élastomère. Sur cette calotte 30, on peut avantageusement déposer une couche satinée 32 telle que de la mousse de silicone par exemple, pour donner au bébé une sensation tactile du type de celle que donne le sein maternel.The possibility is also provided of bringing a cap 30 around the nipple 1 to simulate the maternal breast. This cap 30 is enlarged, hemispherical in shape and manufactured for example from an elastomeric material. On this cap 30, it is advantageous to deposit a satin layer 32 such as silicone foam for example, to give the baby a tactile sensation of the type that that gives the maternal breast.

Le sommet de la calotte 30 est percé d'une ouverture centrale 34 aux dimensions de celles du téton 5 pour permettre le libre passage de ce dernier. La calotte 30 peut ainsi recouvrir le corps 3 de la tétine 1, et son maintien sur le corps 22 du biberon 20 peut être assuré par vissage. A cet effet, la partie supérieure du corps 22 comporte un bossage annulaire 36 dont la périphérie externe possède un filetage 38 destiné à coopérer avec un filetage complémentaire (non représenté) prévu sur la paroi interne de la calotte 30 et à la partie inférieure de celle-ci.The top of the cap 30 is pierced with a central opening 34 to the dimensions of those of the stud 5 to allow the free passage of the latter. The cap 30 can thus cover the body 3 of the nipple 1, and its retention on the body 22 of the bottle 20 can be ensured by screwing. To this end, the part upper body 22 has an annular boss 36 whose outer periphery has a thread 38 intended to cooperate with a complementary thread (not shown) provided on the inner wall of the cap 30 and at the lower part thereof.

Selon une variante de réalisation illustrée à la figure 3, la calotte 30 précitée forme le corps 3 de la tétine 1 et son ouverture centrale 34 se prolonge alors par un téton 5 semblable à celui illustré à la figure 1.According to an alternative embodiment illustrated in FIG. 3, the aforementioned cap 30 forms the body 3 of the nipple 1 and its central opening 34 is then extended by a nipple 5 similar to that illustrated in FIG. 1.
