Abstract

The piercing comprises a central slot (2-2'), there being formed at least at one end of the slot a blind cavity (3) which has a substantially cylindrical profile and whose base, formed at a very slight depth, is cut radially so as to delimit deformable flaps, thereby permitting a functioning in the manner of a valve capable of permitting the intake of air into the feeding bottle while at the same time counteracting the inadvertent passage thereof during the manipulations carried out when the teat is outside the baby's mouth. <IMAGE>

Description

La présente invention a trait aux tétines destinées à être adaptées sur l'ouverture des biberons d'allaitement.The present invention relates to nipples intended to be adapted on the opening of nursing bottles.

On sait que dans leur forme classique, les tétines, réalisées en caoutchouc naturel ou synthétique, comportent, à l'opposé de leur partie ouverte agencée pour se fixer sur le col du biberon, un perçage formé par un ou plusieurs trous aptes à permettre l'écoulement de la bouillie dans la bouche de l'enfant. Il convient toutefois de souligner que bien évidemment ce perçage autorise également la fuite du liquide à l'extérieur du biberon lorsque ce dernier est manipulé alors que la tétine ne se trouve pas encore ou ne se trouve plus dans la bouche du nourrisson.We know that in their classic form, teats, made of natural or synthetic rubber, have, opposite their open part arranged to be fixed on the neck of the bottle, a hole formed by one or more holes suitable for allowing flow of porridge into the child's mouth. It should however be emphasized that obviously this piercing also allows the leakage of the liquid outside the bottle when the latter is handled while the teat is not yet or is no longer in the mouth of the infant.

On observera par ailleurs que l'entrée de l'air à l'intérieur du biberon, entrée qui accompagne évidemment la sortie du liquide hors de celui-ci, perturbe fréquemment le fonctionnement, au point qu'il arrive souvent que la tétine se mette en dépression alors qu'elle est introduite dans la bouche de l'enfant, l'air ne parvenant pas à pénétrer à l'intérieur du biberon.It will also be observed that the entry of air inside the bottle, entry which obviously accompanies the exit of the liquid out of it, frequently disturbs the operation, to the point that it often happens that the teat starts in depression as it is introduced into the mouth of the child, the air not being able to penetrate inside the bottle.

C'est à l'ensemble de ces inconvénients qu'entend remédier la présente invention, laquelle a pour objet une tétine qui tout étant susceptible d'être réalisée en une matière quelconque, naturelle ou synthétique, et tout particulièrement en silicone, est propre à donner entière satisfaction à la mère ou nourrice en évitant toute expulsion inoppinée de liquide et en maîtrisant les déplacements de sens contraires de la bouillie et de l'air.It is to all of these drawbacks that the present invention intends to remedy, which relates to a teat which, all being capable of being made of any material, natural or synthetic, and very particularly of silicone, is suitable for give complete satisfaction to the mother or nurse by avoiding any unexpected expulsion of liquid and by controlling the movements of opposite directions of the porridge and the air.

La tétine suivant l'invention est définie à la revendication.The teat according to the invention is defined in claim.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:

Fig. 1 est une coupe verticale montrant, à une échelle très agrandie, l'agencement du perçage d'une tétine établie conformément à l'invention.Fig. 1 is a vertical section showing, on a very enlarged scale, the arrangement of the bore of a teat established in accordance with the invention.

Fig. 2 est la vue en plan de la face terminale de la tétine qui est tournée vers l'intérieur du biberon.Fig. 2 is the plan view of the end face of the teat which faces towards the inside of the bottle.

Fig. 3 est une coupe de détail, réalisée transversalement par rapport à la fente centrale du perçage.Fig. 3 is a detail section, made transversely to the central slot of the bore.

Fig. 4 est une section suivant le plan indiqué en IV-IV en fig. 1.Fig. 4 is a section along the plane indicated in IV-IV in fig. 1.

Fig. 5 est une coupe suivant le plan indique en V-V en fig. 1.Fig. 5 is a section along the plane indicated in V-V in FIG. 1.

Fig. 6 reproduit fig. 3 lorsque le biberon est orienté avec la tétine tournée vers le bas.Fig. 6 reproduced fig. 3 when the bottle is oriented with the teat facing down.

Sur ce dessin, la référence 1 désigne la paroi qui forme l'extrémité (parfois désignée sous le nom de "téterelle") de la tétine et qui comporte le perçage destiné à permettre le passage de la bouillie liquide, lequel perçage est, à la façon usuelle, disposé à l'intérieur d'une zone délimitée par deux saillies 1a à profil en arc de cercle, opposées l'une à l'autre au niveau de la face extérieure de la paroi 1.In this drawing, the reference 1 designates the wall which forms the end (sometimes referred to as the "nipple") of the nipple and which comprises the bore intended to allow the passage of the liquid slurry, which piercing is, at the usual manner, disposed within an area bounded by two projections 1a to profile in circular arc opposed to each other at the outer face of the wall 1.

Conformément à l'invention, le perçage de la tétine comporte une fente 2 (qui a été supposée à profil rectiligne afin de simplifier la représentation, mais qui est avantageusement établie à un profil brisé afin de faciliter l'écoulement des bouillies relativement épaisses), à chacune des extrémités de laquelle est aménagée une cavité cylindrique borgne 3 qui s'ouvre à l'intérieur de la tétine et dont le fond, à épaisseur très réduite, est découpé par des fentes radiales 4, au nombre de trois dans l'exemple de réalisation envisagé.In accordance with the invention, the piercing of the teat has a slot 2 (which has been assumed to have a straight profile in order to simplify the representation, but which is advantageously established with a broken profile in order to facilitate the flow of relatively thick slurries), at each end of which is fitted a blind cylindrical cavity 3 which opens inside the teat and the bottom of which, with very reduced thickness, is cut by radial slots 4, three in number in the example of envisaged realization.

La fente centrale 2 présente une partie inférieure à profil triangulaire, qui se prolonge vers le haut par une découpe 2' . On observera par ailleurs que le fond supérieur de chaque cavité 3 se trouve disposé à une très faible distance de la face extérieure de la téterelle, de sorte que les membranes ou volets délimités par les fentes radiales 4 comportent une épaisseur très réduite.The central slot 2 has a lower part with a triangular profile, which is extended upwards by a cut 2 '. It will also be observed that the upper bottom of each cavity 3 is located at a very small distance from the external face of the nipple, so that the membranes or flaps delimited by the radial slots 4 have a very reduced thickness.

On comprend ainsi qu'on réalise, de part et d'autre de la fente 2-2' destinée au passage normal de la bouillie de l'intérieur du biberon en direction de la bouche de l'enfant, deux ensembles aptes à se comporter à la manière de clapets, lesquels :

  • s'opposent efficacement à toute expulsion intempestive du liquide lorsque le biberon est manipulé plus ou moins rudement avec la tétine tournée substantiellement vers le haut,
  • autorisent, moyennant la déformation des volets illustrée en fig. 6, la pénétration de l'air dans le biberon au fur et à mesure de la vidange de celui-ci, quand ledit biberon est utilisé avec la tétine tournée plus ou moins obliquement vers le bas et introduite dans la bouche de l'enfant.
It is thus understood that one realizes, on either side of the slot 2-2 'intended for the normal passage of the porridge from the inside of the bottle in the direction of the child's mouth, two sets able to behave like valves, which:
  • effectively oppose any untimely expulsion of the liquid when the bottle is handled more or less roughly with the nipple turned substantially upwards,
  • allow, by means of the deformation of the flaps illustrated in FIG. 6, the penetration of air into the bottle as the latter is emptied, when said bottle is used with the teat turned more or less obliquely downward and introduced into the mouth of the child.

On remarquera que les cavités cylindriques 3 tiennent avantageusement lieu des trous à section circulaire ménagés aux extrémités de la fente centrale des tétines connues réalisées en silicone, ce trous ayant pour but de s'opposer à la déchirure de ladite fente centrale.It will be noted that the cylindrical cavities 3 advantageously take the place of the circular section holes formed at the ends of the central slot of the known teats made of silicone, this hole having the purpose of opposing the tearing of said central slot.
