Abstract

The bottle consists of the bottle itself (1), which is basically rigid and has an open end (10) and a threaded neck (11). There is a deformable teat (2) with a collar (21) which is fastened to the neck of the bottle by a screw cap (3) comprising a threaded skirt and ring. At least one of the four facing surfaces of the bottle neck, teat collar and ring is positioned obliquely relative to the locking direction produced by the threaded surfaces of the bottle neck and cap, so that the locking effort applied to the collar is different in different sectors. In addition, the surface of the teat collar in contact with the bottle neck has a series of oblique channels to allow air passing through the teat into the bottle.

Description

La présente invention a trait aux biberons pour l'allaitement des nourrissons, du genre comprenant un récipient rigide pourvu d'un col fileté, une tétine souple présentant une collerette annulaire propre à venir au contact du bord terminal du col du récipient, et une bague de serrage apte à se visser sur ce col pour appliquer la collerette de la tétine sur celui-ci.The present invention relates to bottles for breastfeeding infants, of the type comprising a rigid container provided with a threaded neck, a flexible teat having a clean annular flange coming into contact with the terminal edge of the neck of the container, and a ring. clamp suitable for screwing on this collar to apply the nipple collar on it.

Les tétines des biberons de ce type sont ordinairement percées d'une ouverture à profil allongé de façon à ce que compte tenu de la pression exercée par les lèvres ou mâchoires du nourrisson sur la téterelle de la tétine, il suffise de modifier l'orientation de celle-ci dans la bouche de l'enfant pour régler le débit de liquide admis dans cette dernière.The nipples of bottles of this type are usually pierced with an elongated profile opening so that, given the pressure exerted by the lips or jaws of the infant on the nipple nipple, it suffices to modify the orientation of the latter in the child's mouth to regulate the flow of liquid admitted into the latter.

Cet agencement ne peut convenir dans tous les cas, notamment dans celui des récipients à profil coudé où il ne peut être question de modifier l'orientation de la tétine dans la bouche de l'enfant. En pareil cas, on a recours à des systèmes de réglage qui agissent non plus par une modification de la section libre de l'ouverture de la tétine, mais par celle du débit d'air admis dans le récipient en remplacement du liquide ingurgité par le nourrisson.This arrangement is not suitable in all cases, especially in that of bent profile containers where there can be no question of changing the orientation of the teat in the mouth of the child. In such cases, recourse is had to adjustment systems which act no longer by a modification of the free section of the opening of the teat, but by that of the air flow admitted into the container in replacement of the liquid ingested by the infant.

C'est ainsi qu'on a proposé de faire comporter à la face de la collerette qui est appliquée contre le bord terminal du récipient, des canaux de mise à l'air libre qui sont plus ou moins obturés en fonction du degré de serrage de la bague filetée. On conçoit effectivement que l'effort de serrage exercé sur la bague tend à écraser la collerette de la tétine en modifiant la section des canaux précités.Thus it has been proposed to make the face of the flange which is applied against the terminal edge of the container have ventilation channels which are more or less closed depending on the degree of tightness of the threaded ring. It is effectively understood that the tightening force exerted on the ring tends to crush the collar of the teat by modifying the section of the aforementioned channels.

L'expérience démontre toutefois que la plage de réglage dont dispose l'utilisatrice est extrêmement réduite, au point que sur le plan pratique le réglage du débit est très pointu et en conséquence malaisé.Experience has shown, however, that the adjustment range available to the user is extremely small, to the point that, in practical terms, the adjustment of the flow rate is very precise and consequently difficult.

C'est à cet inconvénient qu'entend plus spécialement remédier la présente invention, laquelle a pour objet le biberon d'allaitement qui est défini à la revendication 1.It is to this drawback that the present invention more specifically intends to remedy, which relates to the nursing bottle which is defined in claim 1.

Le biberon d'allaitement à débit réglable suivant l'invention, du genre comprenant à la façon en soi connue :

  • un récipient substantiellement rigide pourvu d'un col à périphérie cylindrique filetée ;
  • une tétine déformable dont la téterelle comporte une collerette annulaire orientée de manière substantiellement radiale par rapport à l'axe du filetage du col, les deux faces en regard de ce col et de la collerette définissant entre elles des canaux pour la mise à l'air libre du volume intérieur du récipient ;
  • et une bague rigide de serrage qui présente une jupe latérale filetée pour coopérer avec le col et un fond annulaire en contact avec la collerette de la tétine,
est caractérisé en ce que l'une au moins des quatre faces en regard du col du récipient, de la collerette de la tétine et du fond annulaire de la bague est orientée obliquement par rapport à la direction de serrage définie par les filetages du col et de la bague, afin que l'effort de serrage exercé sur la collerette soit différent dans différents secteurs de cette collerette.The feeding bottle with adjustable flow rate according to the invention, of the type comprising in the known manner:
  • a substantially rigid container with a neck with a threaded cylindrical periphery;
  • a deformable teat, the teat of which comprises an annular flange oriented substantially radially with respect to the axis of the thread of the neck, the two opposite faces of this neck and the flange defining between them channels for the venting free from the interior volume of the container;
  • and a rigid clamping ring which has a threaded side skirt to cooperate with the neck and an annular bottom in contact with the collar of the teat,
is characterized in that at least one of the four faces opposite the neck of the container, the collar of the teat and the annular bottom of the ring is oriented obliquely with respect to the tightening direction defined by the threads of the neck and of the ring, so that the clamping force exerted on the collar is different in different sectors of this collar.

On comprend qu'on obtient ainsi une très large plage angulaire de réglage, qui facilite considérablement les opérations de réglage de débit.It is understood that a very wide angular adjustment range is thus obtained, which considerably facilitates the flow adjustment operations.

On conçoit que ce résultat favorable est obtenu quelle que soit la pièce (col du récipient, collerette de la tétine ou fond de la bague) qui comporte l'obliquité, et quelle que soit celle des deux faces en regard (bord terminal du col ou face inférieure de la collerette) qui est creusée pour définir les canaux de mise à l'air libre. Toutefois, conformément à celui des modes de mise en oeuvre de l'invention qui lors des essais s'est révélé le plus avantageux, c'est la collerette de la tétine qui est conformée par moulage pour présenter l'obliquité désirée et les canaux de mise à l'air libre.It is understood that this favorable result is obtained whatever the part (neck of the container, collar of the teat or bottom of the ring) which has the obliquity, and whatever that of the two opposite faces (end edge of the neck or underside of the collar) which is hollowed out to define the venting channels. However, in accordance with that of the embodiments of the invention which during the tests has proved to be the most advantageous, it is the collar of the teat which is shaped by molding to present the desired obliquity and the channels of venting.

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 :

  • Fig. 1 est une coupe axiale schématique montrant la partie supérieure d'un biberon suivant l'invention, représenté avant serrage de la bague.
  • Fig. 2 est une vue en perspective par dessous montrant à l'état séparé la tétine qui équipe le biberon suivant fig. 1.
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 is a schematic axial section showing the part upper of a bottle according to the invention, shown before tightening of the ring.
  • Fig. 2 is a perspective view from below showing in a separate state the nipple which equips the bottle according to fig. 1.

Le biberon représenté comprend un récipient 1 réalisé en une matière rigide telle que le verre. Ce récipient 1 présente à sa partie supérieure ouverte un col 10 dont la paroi extérieure est pourvue d'un filetage 11.The bottle shown comprises a container 1 made of a rigid material such as glass. This container 1 has at its open upper part a neck 10, the outer wall of which is provided with a thread 11.

La face terminale du col 10 est destinée à former appui pour la base d'une tétine 2 qui est réalisée en une matière souple et déformable telle que le caoutchouc naturel ou synthétique et dont la téterelle 20 est percée d'une ouverture pour le passage du liquide ou bouillie contenu dans le récipient 1. la base de cette tétine 2 est en fait constituée par une collerette 21 orientée perpendiculairement à l'axe de ladite tétine. Comme on peut le voir en fig. 2, la face de cette collerette 21 qui est tournée à l'opposé de la téterelle 20 est creusée d'une série de dépressions ou canaux 22 dont les extrémités débouchent au niveau des deux bords concentriques de la collerette 21. On notera que cette dernière est surmontée d'une nervure 23 (fig. 1).The end face of the neck 10 is intended to form a support for the base of a nipple 2 which is made of a flexible and deformable material such as natural or synthetic rubber and whose nipple 20 is pierced with an opening for the passage of the liquid or boiled contained in the container 1. the base of this teat 2 is in fact constituted by a collar 21 oriented perpendicular to the axis of said teat. As can be seen in fig. 2, the face of this flange 21 which is turned away from the nipple 20 is hollowed out with a series of depressions or channels 22, the ends of which open out at the two concentric edges of the flange 21. It will be noted that the latter is surmounted by a rib 23 (fig. 1).

Le biberon est complété par une bague de serrage 3 réalisée en une matière plastique rigide. Cette bague 3 comporte une jupe cylindrique dont la paroi intérieure présente un filetage 30 apte à coopérer avec celui 11 du col 10. Cette jupe se raccorde à un fond supérieur 31, établi sous forme annulaire afin de permettre le passage de la partie inférieure de la tétine 2 qui est retenue en place par la nervure 23 une fois la collerette 21 introduite à l'intérieur de la bague moyennant déformation élastique momentanée.The bottle is completed by a clamping ring 3 made of a rigid plastic material. This ring 3 comprises a cylindrical skirt whose inner wall has a thread 30 capable of cooperating with that 11 of the neck 10. This skirt is connected to an upper bottom 31, established in annular form in order to allow the passage of the lower part of the nipple 2 which is retained in place by the rib 23 once the flange 21 is inserted inside the ring by means of momentary elastic deformation.

Conformément à l'invention, la collerette 21 de la tétine 2 présente un profil orienté obliquement par rapport à l'axe X-X du récipient 1. En d'autres termes, l'épaisseur de la collerette 21 va en croisant diamétralement d'un bord à l'autre, en définissant ainsi une face supérieure oblique.According to the invention, the collar 21 of the teat 2 has a profile oriented obliquely with respect to the axis XX of the container 1. In other words, the thickness of the collar 21 is crossed diametrically from one edge to the other, thereby defining an oblique upper face.

Par suite de cette obliquité, lors du vissage de la bague 3 sur le col 10, la face inférieure du fond 31 vient en premier lieu porter contre la partie ou secteur de la collerette 21 qui présente la plus forte épaisseur (à gauche en fig. 1 et 2), si bien que ce secteur subit un écrasement avant les autres secteurs de la face inférieure de ladite collerette. La déformation qui fait suite à cet écrasement localisé assure l'obturation du ou des canaux 22 qui sont placés au niveau du secteur envisagé, cette obturation survenant progressivement au cours du serrage de la bague 3 et intéressant de manière séquentielle les différents canaux.As a result of this obliquity, when the ring 3 is screwed onto the neck 10, the underside of the bottom 31 comes first to bear against the part or sector of the flange 21 which has the greatest thickness (on the left in FIGS. 1 and 2), so that this sector is crushed before the others sectors of the underside of said collar. The deformation which follows this localized crushing ensures the obturation of the channel or channels 22 which are placed at the level of the envisaged sector, this obturation occurring gradually during the tightening of the ring 3 and sequentially affecting the different channels.

On conçoit qu'on dispose de la sorte d'une large plage angulaire pour le réglage parfaitement précis du débit d'air qui pénètre dans le récipient 1 à travers les canaux 22 et qui correspond évidemment au débit de liquide finalement admis dans la bouche du nourrisson. L'opération de réglage est en conséquence aisée.It is understood that there is thus a wide angular range for the perfectly precise adjustment of the air flow rate which enters the container 1 through the channels 22 and which obviously corresponds to the flow rate of liquid finally admitted into the mouth of the infant. The adjustment operation is therefore easy.

Bien évidemment, le système de réglage suivant l'invention est particulièrement avantageux dans le cas des biberons à récipient coudé, ou de ceux dans lesquels c'est la tétine 2 elle-même qui présente un profil coudé, comme on l'a supposé au dessin.Obviously, the adjustment system according to the invention is particularly advantageous in the case of bottles with an angled container, or of those in which it is the teat 2 itself which has an angled profile, as has been supposed in drawing.
