PCT No. PCT/EP86/00503 Sec. 371 Date Jun. 29, 1987 Sec. 102(e) Date Jun. 29, 1987 PCT Filed Aug. 28, 1986 PCT Pub. No. WO87/01277 PCT Pub. Date Mar. 12, 1987.The feeding nipple contains an annular connecting part the outer face of which defines a base plane and a central longitudinal axis perpendicular thereto, as well as a hemispherical shell and a hollow nozzle portion, integrally formed onto it via a narrowed neck part, having a suction opening in its rounded tip. All components form a one-piece hollow body of an elastomeric material which is mirror-symmetrical with respect to a plane of symmetry containing the longitudinal axis. A plane of division, perpendicular to the plane of symmetry and axially dividing the hollow nozzle portion in a longitudinal direction intersects the longitudinal axis near the base plane and is spaced apart from it at the apex of the rounded tip by approximately 6 mm. The hollow nozzle portion, including the neck part is limited on the inside by ellipses parallel to the base plane, the minor axes of which are located in the plane of symmetry, and all points of the ellipses are located within a reference intersection curve at the narrowest outer cross section of the neck at a minimum distance of 0.5 mm. The hollow nozzle portion includes a thickened region, the maximum value of which is located for approximately half of its length in the plane of symmetry. The feeding nipple can be produced economically and in a shape optimized for pressure molding (injection molding).

Description

Die Erfindung betrifft einen orthodontischen Flaschensauger, bestehend aus einem einstückigen, einwandigen Hohlkörper aus gummielastischem Werkstoff, enthaltend einen zur Befestigung an einer Trinkflasche bestimmten ringförmigen Anschlussteil, der koaxial zu einer Längsachse angeordnet ist und mit seiner einen äusseren Stirnfläche in einer ersten, zu dieser Längsachse lotrechten Basisebene liegt, eine in Form eines Rotationskörpers mit der Längsachse als Achse ausgebildete näherungsweise die Gestalt einer halben Hohlkugel aufweisende, mit ihrem Rand an die andere Stirnfläche des Anschlussteiles angeformte und eine Öffnung in einem von der Basisebene abgewandten Bereich aufweisende Schale, einen an seinem freien Ende mit einer gerundeten Kuppe abgeschlossenen Hohlzapfen, der an seinem anderen Ende einen verengten Halsteil aufweist, dessen Wanddicke in einer zur Basisebene parallelen, durch die Stelle seines geringsten Aussenquerschnittes gelegten Bezugsebene über den ganzen Umfang im wesentlichen gleich groß ist und der an die Öffnung der Schale angeformt ist, wobei der gesamte Hohlkörper spiegelbildlich bezüglich einer die Längsachse und die Bohrungsachse einer die Wand des Hohlzapfens durchdringende Saugöffnung enthaltenden Symmetrieebene geformt ist, und der von der Basisebene maximal weit entfernte Scheitel der Aussenfläche des Hohlzapfens auf einer zur Symmetrieebene lotrechten, eine Versetzung zu der Längsachse aufweisende Scheitelgeraden liegt, und die durch Schnitt der Innenfläche des Hohlzapfens mit beliebigen, zur Basisebene parallelen Querebenen entstehenden Innenflächen-Schnittkurven näherungsweise die Form von Ellipsen aufweisen, deren kleine Achsen die Schnittlinien der Symmetrieebene mit den jeweils zugeordneten Querebenen bilden.The invention relates to an orthodontic bottle teat, consisting of a one-piece, single-walled hollow body made of rubber-elastic material, containing an annular connecting part intended for attachment to a drinking bottle, which is arranged coaxially to a longitudinal axis and with its outer end face in a first, perpendicular to this longitudinal axis The base plane is a shell, which is designed in the form of a rotating body with the longitudinal axis as an axis and approximately has the shape of a half hollow sphere, with its rim molded onto the other end face of the connection part and an opening in a region facing away from the base plane, one at its free end with a rounded cap closed hollow pin, which has a narrowed neck portion at its other end, the wall thickness in a parallel to the base plane, by the location of its smallest outer cross-section reference plane over the entire circumference in the we is substantially the same size and which is molded onto the opening of the shell, the entire hollow body being formed in mirror image with respect to a plane of symmetry containing the longitudinal axis and the bore axis of a suction opening penetrating the wall of the hollow pin, and the apex of the outer surface of the outer surface which is at a maximum distance from the base plane The hollow pin lies on a vertex line perpendicular to the plane of symmetry, offset from the longitudinal axis, and which have approximately the shape of ellipses due to intersection of the inner surface of the hollow pin with any transverse planes parallel to the base plane, whose small axes form the intersection lines of the plane of symmetry with the respectively assigned transverse planes.

Bekannte Flaschensauger dieser Art werden im Tauchverfahren hergestellt, das einerseits produktionstechnisch aufwendig ist und andererseits es nur erlaubt, alle Wandungen mit einer im wesentlichen gleichen Wanddicke auszubilden. Soweit es im medizinischen Interesse geboten wäre, Bereiche des Flaschensaugers mit einer vergrösserten Wanddicke auszustatten, müssen daher Einschränkungen ringenommen werden.Known bottle nipples of this type are produced by the immersion process, which on the one hand is complex in terms of production technology and on the other hand only allows all walls to be formed with an essentially the same wall thickness. To the extent that it would be of medical interest to equip areas of the bottle teat with an increased wall thickness, restrictions must therefore be accepted.

Im Vergleich zu der Ausbildung nach einer normalen Entwicklung befindet sich bei der Geburt eines Kindes der Unterkiefer in einer zurückgezogenen Lage und es weist der Gaumen eine verhältnismässig zusammengedrückte Form auf.Compared to training after normal development, the lower jaw is in a retracted position when a child is born and the palate has a relatively compressed shape.

Bei der natürlichen Ernährung durch die Mutter drückt das Kind die Brustwarze mit der Zunge gegen seinen Gaumen und stimuliert die Milchabgabe durch pulsierenden Druck cer Zunge auf die Brustwarze, welche diese Druckstösse aufgrund ihrer Form und Gewebestruktur an den Gaumen weitergibt. Dieser reagiert darauf, indem er wächst. Die Druckstösse wirken auch auf den Unterkiefer und zwingen ihn fortwährend nach vorne. Der Unterkiefer reagiert darauf, indem er seine Lage allmählich nach vorne verlegt. Die erläuterten Zungenbewegungen werden vom Kind grundsätzlich immer durchgeführt, wenn es wach ist; sie sind jedcch besonders stark während der Ernährung ausgeprägt, die damit für die gute Ausformung der oben genannten Körperteile eine besondere Bedeutung erhält. Mit bekannten Fla- schensaugern der eingangs genannten Art wurde bereits angestrebt, der Brusternährung vergleichbare Effekte bei der Entwicklung des Kindes zu erreichen, ohne allerdings diesem Ziel in wünschenswerter Weise nahe zu kommen.In the natural feeding by the mother, the child presses the nipple against the roof of the mouth with the tongue and stimulates the delivery of milk by pulsating pressure on the nipple, which transmits these pressure surges to the roof of the mouth due to their shape and tissue structure. This reacts to this by growing. The pressure surges also affect the lower jaw and continuously force it forward. The lower jaw reacts to this by gradually moving its position forward. The tongue movements described are always carried out by the child when he is awake; However, they are particularly pronounced during the diet, which is responsible for the good shaping of the above Body parts takes on a special meaning. With known F la- rule teats of the type mentioned has already sought the B rust nutritionally comparable effects in the development of the child to achieve, but without that goal to get close desirably.

Aufgabe der Erfindung ist es, einen Flaschensauger der eingangs genannten Art hinsichtlich seiner Formgebung so weiterzubilden, dass er sowohl wirtschaftlicher herstellbar ist, als auch durch seinen Gebrauch eine optimale Entwicklung des Gaumens und Unterkiefers, sowie des Saugvermögens sichert.The object of the invention is to develop a bottle teat of the type mentioned in terms of its shape so that it is both more economical to manufacture and ensures optimal development of the palate and lower jaw as well as the absorbency through its use.

Diese Aufgabe wird erfindungsgemäss dadurch glöst, dass die Innenfläche des Hohlzapfens einschliesslich seiner Kuppe und eines bis zur Bezugsebene reichenden Abschnittes seines Halsteils, so gestaltet ist, dass jeder Punkt jeder der Innenflächen-Schnittkurven bei seiner parallel zur Längsachse erfolgenden Projektion auf die Bezugsebene innerhalb der durch den Schnitt der Aussenfläche des Hohlzapfens mit der Bezugsebene gebildeten Bezugs-Schnittkurve liegt und zu dieser einen Abstand von mindestens 0,5 mm einhält, dass eine in der Bezugsebene liegende, zur Symmetrieebene lotrechte; die Bezugs-Schnittkurve mittig teilende Bezugsgerade zur Längsachse eine Versetzung von 2,3 bis 3,3 mm in der gleichen Richtung wie die Versetzung der Scheitelgeraden aufweist, dass der erste Wandungsteil des Hohlzapfens, der sich auf der den Schnittpunkt der Bezugsebene mit der Längsachse enthaltenden einen Seite einer durch die Scheitelgeraden und die Bezugsgeraden gelegten Teilungsebene befindet, eine im wesentlichen gleichförmige Wanddicke entsprechend der Wanddicke in der Bezugsebene aufweist und dass der auf der anderen Seite der Teilungebene gelegene zweite Wandungsteil eine mit zunehmender Annäherung an eine zentral gelegene Stelle kontinuierlich einem Grösstwert zustrebende Wanddicke aufweist, wobei dieser Grösstwert gleich dem 1,5 bis 3-fachen der Wanddicke in der Bezugsebene ist.This object is achieved according to the invention in that the inner surface of the hollow pin, including its tip and a section of its neck part reaching to the reference plane, is designed in such a way that each point of each of the inner surface intersection curves is parallel to the longitudinal axis when it is projected onto the reference plane within the through the intersection of the outer surface of the hollow pin with the reference plane formed reference reference curve and maintains a distance of at least 0.5 mm from this that a lying in the reference plane, perpendicular to the plane of symmetry; the reference intersection curve dividing the reference straight line in the middle to the longitudinal axis has an offset of 2.3 to 3.3 mm in the same direction as the offset of the apex straight line, that the first wall part of the hollow pin, which is located on the point of intersection of the reference plane with the longitudinal axis one side of a division through the apex line and the reference line plane, has a substantially uniform wall thickness corresponding to the wall thickness in the reference plane and that the second wall part located on the other side of the division plane has a wall thickness which continuously approaches a maximum value as it approaches a central location, this maximum value being equal to 1, 5 to 3 times the wall thickness in the reference plane.

Durch diese Ausbildung wird erreicht, dass der Flaschensauger durch Pressen (Spritzen) in einer einfach gebauten, einen ungeteilten Kern aufweisenden Form herstellbar ist. Hierdurch lassen sich im Vergleich zu üblicherweise zur Herstellung angewandten TauchverfahrEn produktionstechnische Vorteile erzielen und es kennen gezielt unterschiedliche Wendstärken an vorbestimmten Stellen des Flaschensaugers ausgebildet werden, so dass neben der Gestaltung der Aussenfläche die Voraussetzungen für eine zusätzliche Optimierung des Flaschensaugers gegeben sind.This configuration ensures that the bottle teat can be manufactured by pressing (spraying) in a simply constructed form with an undivided core. In this way, compared to the immersion methods usually used for manufacturing, production-technical advantages can be achieved and different turning strengths can be specifically formed at predetermined locations on the bottle teat, so that in addition to the design of the outer surface, the requirements for an additional optimization of the bottle teat are given.

Die Versetzung der Bezugsgeraden bedeutet, dass der Hohlzapfen nicht nur, wie bei blosser Versetzung seiner Scheitelgeraden, geneigt zur Schale vorsteht, sondern dass auch seine Ansatzstelle an der Schale aus der Mitte versetzt ist. Damit wird in Zusammenhang mit der von den Lippen des Kindes umfassten Schale erreicht, dass die unter dem Hohlzapfen liegende Zunge genügend Freiraum erhält. Der (zungenseitige bzw. dem Unterkiefer zugewandte) dünne erste Wandungsteil des Hohlzapfens bietet keinen unerwünscht grossen Widerstand gegen die Druck- bzw. Saugimpulse der Zunge, wodurch die Entnahme der Flüssigkeit mittels des Flaschensaugers gewährleistet ist und das Kind dazu angeregt wird, die notwendigen Zun- - genbewegurgen fortzuführen. Der gaumenseitige dickere zweite Wandungsteil des Hohlzapfens sorgt dafür, dass die richtige Lage im Mund, d.h. gegen den Gaumen und tief in den Mund hineinragend, auch tatsächlich erreicht wird. Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen.The offset of the reference straight line means that the hollow spigot not only protrudes to the shell at an angle, as in the case of a straight offset of its apex straight line, but also that its attachment point on the shell is offset from the center. In connection with the shell encompassed by the child's lips, this ensures that the tongue lying under the hollow pin is given sufficient space. The thin first wall part of the hollow pin (on the tongue side or facing the lower jaw) does not offer an undesirably high resistance to the pressure or suction impulses of the tongue, as a result of which The bottle teat ensures that the liquid is withdrawn and the child is encouraged to continue the necessary tongue movements. The thicker second wall part of the hollow pin on the palate ensures that the correct position in the mouth, that is to say, protruding against the palate and deep into the mouth, is actually achieved. Further features and advantages of the invention emerge from the subclaims.

Der Flaschensauger ist von einem einstückig aus einem gummielastischen Werkstoff, beispielsweise Gummi oder Silikon, durch Pressen hergestellter, in seiner Gesamtheit mit 1 bezeichneten Hohlkörper gebildet. Dieser Hohlkörper setzt sich im wesentlichen zusammen aus einem Anschlussteil 2, einer Schale 3 und einem Hohlzapfen 4 mit seinem Halsteil 4a.The bottle teat is formed by a hollow body which is produced in one piece from a rubber-elastic material, for example rubber or silicone, by pressing and is designated in its entirety by 1. This hollow body is composed essentially of a connecting part 2, a shell 3 and a hollow pin 4 with its neck part 4a.

Der Anschlussteil 2 ist zur Befestigung an einer Trinkflasche bestimmt und hat im wesentlichen die Form einer Ringscheibe, deren äussere zylindrische Umfangsfläche 2a und innere zylindrische Umfangsfläche (Bohrung) 2b koaxial zu einer Längsachse A angeordnet sind.

The outer end face 2c, which faces away from the remaining parts of the bottle teat, forms a contact surface which, when the bottle teat is in use, lies against the front edge of the drinking bottle mouth and is located in a base plane B 0 perpendicular to the longitudinal axis A. Adjacent to the outer circumferential surface 2a, an annular bead 2e with a triangular cross section projects from the other inner end surface 2d. Radially within this annular bead 2e, several ventilation bores 2f penetrate the connecting part.

Gegenüber seiner Basis weist die Schale 3 eine Öffnung auf, die in einer die Längsachse A enthaltenden Symmetrieebene (welche der Zeichnungsebene der Fig. 1 entspricht) bezüglich dieser Längsachse A versetzt angeordnet ist.The shell 3 has approximately the shape of a half hollow sphere, the wall thickness C 1 of which decreases from a maximum dimension in the region of its base with increasing approach to the longitudinal axis A. The shell 3 is arranged coaxially to the longitudinal axis A and connected to the connection part 2 via a collar 6, the diameter of the inner peripheral surfaces of these three components being the same are large, and the outer peripheral surface 6a of the collar 6 has a smaller diameter than the shell 3 at their - has base, so that a radially outwardly open annular groove 6b ensteht after.
