Description

Die Erfindung bezieht sich auf eine Saugflasche mit einer Flasche, einem Trinksauger, einem Schraubring zum Befestigen des Trinksaugers an einem Öffnungsrand einer Flaschenöffnung und einer Abdeckkappe zum Aufsetzen auf den Schraubring.The invention relates to a feeding bottle with a bottle, a teat, a screw ring for attaching the teat to an opening edge of a bottle opening and a cap for placing on the screw ring.

Saugflaschen werden zur Verabreichung von Milch und anderer flüssiger Nahrung insbesondere an Kinder verwendet. Selen zum Beispiel die Saugflasche in der US2571010A1 beschrieben. Bekannte Saugflaschen weisen eine Flasche und einen Trinksauger auf, der mittels eines Schraubringes an einem Außengewinde der Flasche fixierbar ist, welches die Öffnung der Flasche umgibt. Eine Abdeckkappe ist auf den Schraubring aufsetzbar. Zwischen den Schraubring und den Öffnungsrand der Flasche ist eine Dichtscheibe bzw. ein Rand des Trinksaugers abdichtend einklemmbar. Hierdurch wird ein unbeabsichtigtes Auslaufen von Nahrung verhindert. Eine derartige Saugflasche ist in der DE 33 37 248 A1 beschrieben.Suction bottles are used to administer milk and other liquid food, especially to children. Selenium for example the feeding bottle in the US2571010A1 described. Known feeding bottles have a bottle and a teat, which is fixable by means of a screw ring on an external thread of the bottle, which surrounds the opening of the bottle. A cap is placed on the screw ring. Between the screw ring and the opening edge of the bottle, a sealing washer or an edge of the teat is sealingly clamped. This prevents inadvertent leakage of food. Such a feeding bottle is in the DE 33 37 248 A1 described.

Die CH 261 501 A , US 5 419 445 A und US 2 579 194 A offenbaren Saugflaschen mit Trinksaugern und Abdeckkappen, die in aufgesetzter Position mit der Innenseite ihres Bodens auf dem Trinkloch im Zentrum des Saugernippels aufsitzen. Der Boden der Kappe ist an der Innenseite konkav gewölbt und an dieser konkaven Wölbung liegt der Saugernippel mit dem zentralen Trinkloch abdichtend an.The CH 261 501 A . US Pat. No. 5,419,445 and US 2 579 194 A disclose suction bottles with teat cups and caps, which sit in an attached position with the inside of their bottom on the drinking hole in the center of the nipple nipple. The bottom of the cap is concavely curved on the inside and at this concave curvature of the nipple with the central drinking hole sealingly.

Aus der WO 99/03442 A1 ist eine Abdeckkappe bekannt, die an die äußere Form des Trinksaugers angepasst ist, um jeglichen Zwischenraum zwischen Abdeckkappe und Trinksauger zu vermeiden. Oben dichtet die Innenseite der Abdeckkappe ein Trinkloch am Scheitel des Trinksaugers ab, um den Austritt von Milch zu verhindern. Für die Nahrungsentnahme ist ein Teil der Abdeckkappe von ihrem Körper durch Aufreißen eines Aufreißstreifens ablösbar. Diese Abdeckung eignet sich nur für Einmalbenutzung. Die abgenommene Abdeckkappe ist nicht wieder dichtend aufsetzbar.From the WO 99/03442 A1 a cap is known, which is adapted to the outer shape of the teat to avoid any gap between the cap and teat. At the top, the inside of the cap seals a drinking hole at the top of the teat to prevent the escape of milk. For the removal of food, a part of the cap is removable from her body by tearing a tear strip. This cover is suitable only for single use. The removed cap is not resealable.

Die EP 0 527 094 A1 offenbart eine Saugflasche mit einer Kappe, die auf eine Rille der Außenseite eines Schraubringes aufschnappbar ist. Die Kappe enthält eine flexible Membran die fest mit einer am Boden der Kappe angeordneten Muffe verbunden ist. Die Membran formt sich elastisch und dichtet das Trinkloch des Trinksaugers ab, wenn die Kappe auf den Schraubring aufgesetzt ist. Die Kappe ist aufwendig und schwer zu reinigen. Bei orthodontisch geformten Saugern, bei denen das Trinkloch in einer Seitenfläche des Kopfteils des Saugernippels angeordnet und spitzwinklig zur Saugerachse ausgerichtet ist, passt sich die Membran nach einer gewissen Auswölbung an das Trinkloch an und dichtet ab. Der Anlagedruck der Membran an den Öffnungsrand des Trinksaugers ist infolgedessen verhältnismäßig gering, so dass es zu Undichtigkeiten kommen kann.The EP 0 527 094 A1 discloses a suction bottle with a cap which can be snapped onto a groove on the outside of a screw ring. The cap includes a flexible membrane fixedly connected to a sleeve located at the bottom of the cap. The membrane forms elastically and seals the drinking hole of the teat when the cap is placed on the screw ring. The cap is complex and difficult to clean. In orthodontically shaped suckers in which the drinking hole is arranged in a side surface of the head part of the nipple and aligned at an acute angle to the nipple axis, the membrane adapts after a certain bulge to the drinking hole and seals. The plant pressure of the membrane at the opening edge of the teat is consequently relatively small, so that it can lead to leaks.

Aus der DE 92 14 438 U1 und der DE 93 18 699 U1 ist eine Babyflasche mit einer Abdeckkappe bekannt, deren Höhe niedriger als die Saugerhöhe ist. Infolgedessen drückt die Abdeckkappe mit dem Boden einer Kammer gegen Trinklöcher des Trinksaugers und dichtet sie ab. Ein orthodontisch geformter Trinksauger wird hierbei beträchtlich verformt, so dass am Ende der Verformung in eine zur Mittelachse geneigte Seite des Trinksaugersaugers angeordnetes Trinkloch mit seinem Rand abdichtend am Boden der Kappe anliegt. Die hierbei auftretenden Dichtkräfte sind verhältnismäßig gering, so dass es zu Undichtigkeiten kommen kann.From the DE 92 14 438 U1 and the DE 93 18 699 U1 is a baby bottle with a cap known whose height is lower than the suction height. As a result, the cap presses against the bottom of a chamber against drinking holes of the teat and seals them off. An orthodontically shaped teat is hereby considerably deformed, so that at the end of the deformation in a side inclined to the central axis side of the teat arranged drinking hole with its edge sealingly abuts the bottom of the cap. The sealing forces occurring in this case are relatively small, so that it can lead to leaks.

Aus der DE 200 09 823 U1 ist eine Säuglingsflasche mit einem flexiblen Sauger bekannt, der um das Trinkloch herum einen Kompressionsabschnitt aufweist. Eine flexible Kappe hat einen an ihrer oberen Innenseite ausgebildeten Eingriffsabschnitt, dessen Form derjenigen des Kompressionsabschnitts entspricht. Der Eingriffsabschnitt kann auf den Kompressionsabschnitt gepresst werden, damit dieser um eine vorgegebene Tiefe eingesenkt wird, wenn die Kappe auf den Haltering gesetzt wird, wodurch ein Auslaufen von im Flüssigkeitsbehälter enthaltener Flüssigkeit durch das Trinkloch des Saugers wirksam verhindert wird. Diese Konstruktion ist für einen orthodontisch geformten Sauger mit einem Trinkloch in einer zur Mittelachse geneigten Seitenfläche des Saugernippels nicht geeignet.From the DE 200 09 823 U1 For example, a baby bottle with a flexible nipple is known that has a compression portion around the drinking hole. A flexible cap has an engaging portion formed on its upper inner side, whose shape corresponds to that of the compression section. The engagement portion may be pressed on the compression portion to be lowered by a predetermined depth when the cap is placed on the retaining ring, thereby effectively preventing leakage of liquid contained in the liquid container through the nipple of the nipple. This construction is not suitable for an orthodontically shaped teat with a drinking hole in a side surface of the teat nipple inclined to the central axis.

Die WO 98/15463 A1 offenbart eine Saugflasche mit einem Trinksauger und einer Abdeckkappe. Die Abdeckkappe hat am Boden einen nach unten vorstehenden Vorsprung, der in dichtenden Eingriff mit einem Trinkloch am Scheitel des Saugernippels kommt. Diese Konstruktion ist für einen orthodontischen Trinksauger mit einem Trinkloch in einer geneigten Seitenfläche des Saugernippels ungeeignet.The WO 98/15463 A1 discloses a feeding bottle with a teat and a cap. The cap has at the bottom a downwardly projecting projection which comes into sealing engagement with a drinking hole at the apex of the nipple nipple. This construction is unsuitable for an orthodontic teat with a drinking hole in an inclined side surface of the teat nipple.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Saugflasche zur Verfügung zu stellen, die einen orthodontisch geformten Trinksauger einfacher und sicherer abdichtet.Based on this, the present invention seeks to provide a feeding bottle available that seals an orthodontically shaped teat easier and safer.

Die Aufgabe wird durch eine Saugflasche mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen der Saugflasche sind in den Unteransprüchen angegeben.The object is achieved by a suction bottle with the features of claim 1. Advantageous embodiments of the feeding bottle are specified in the subclaims.

Die erfindungsgemäße Saugflasche insbesondere für Säuglinge und Kleinkinder hat

  • eine Flasche, die eine Flaschenöffnung und ein diese umgebendes Außengewinde aufweist,
  • einen Trinksauger, der einen Nippelträger mit einem Befestigungsrand und auf dem Nippelträger einen Saugernippel mit einem Trinkloch in einer Seitenfläche aufweist,
  • einen Schraubring, der ein Innengewinde zum Aufschrauben auf das Außengewinde und Mittel zum Verbinden mit dem Befestigungsrand des Trinksaugers, um den Trinksauger vor der Flaschenöffnung zu halten, aufweist, und
  • eine Abdeckkappe, die auf den Trinksauger aufsetzbar ist, wobei die Abdeckkappe in aufgesetzter Position mit der Innenseite ihrer Seitenwand abdichtend gegen die das Trinkloch aufweisende Seitenfläche des Saugernippels und mit der Innenseite ihres Bodens gegen eine gegenüberliegende Seitenfläche des spitzwinklig zur Zentralachse des Befestigungsrandes ausgerichteten Saugernippels drückt.
The inventive feeding bottle especially for infants and toddlers has
  • a bottle having a bottle opening and a surrounding external thread,
  • a teat having a nipple carrier with a fastening edge and on the nipple carrier a nipple with a drinking hole in a side surface,
  • a screw ring having an internal thread for screwing onto the external thread and means for connecting to the mounting edge of the teat to hold the teat in front of the bottle opening, and
  • a cap which can be placed on the teat, wherein the cap in sealing position with the inside of its side wall sealingly presses against the side facing the drinking hole side nipple and with the inside of its bottom against an opposite side surface of the acute-angled to the central axis of the mounting edge nipple.

Bei der erfindungsgemäßen Saugflasche wird der Saugernippel des Trinksaugers an seinem freien, vom Befestigungsrand entfernten Ende im Eckbereich zwischen Seitenwand und Boden der Abdeckkappe festgehalten. Hierbei liegt die Seitenwand an der Seitenfläche des Saugernippels an, die das Trinkloch aufweist. Der Boden liegt an der gegenüberliegenden Seitenfläche des Saugernippels an. Infolgedessen wird die von der Seitenwand der Abdeckkappe in die Seitenfläche mit dem Trinkloch eingeleitete Kraft über die gegenüberliegende Seitenfläche des Saugernippels am Boden der Abdeckkappe abgestützt. Somit liegt die Seitenwand mit einer besonders hohen Andrückkraft am Randbereich des Trinkloches an, so dass es zu einer sehr guten Abdichtung zwischen diesem Randbereich und der Seitenwand kommt. Die Ausrichtung des Saugernippels auf den Eckbereich zwischen Seitenwand und Boden der Abdeckkappe kann dadurch erreicht werden, dass der Trinksauger einen bereits im unbelasteten Zustand spitzwinklig zur Zentralachse des Befestigungsrandes des Nippelträgers ausgerichteten Saugernippel hat. Bei einem Trinksauger mit in unbelastetem Zustand auf der Zentralachse angeordnetem Saugernippel kann sie dadurch erreicht werden, dass der Saugernippel durch die aufgesetzte Abdeckkappe in eine spitzwinklige Ausrichtung zum Befestigungsrand gezwungen wird. Aufgrund des schräg gestellten Saugernippels ist das freie Ende des Saugernippels bei aufgesetzter Abdeckkappe zwischen Boden und Seitenwand eingezwängt und das Trinkloch wird sicher abgedichtet.In the suction bottle according to the invention, the nipple of the teat is held at its free end remote from the fastening edge in the corner region between the side wall and the bottom of the cap. Here, the side wall abuts the side surface of the nipple, which has the drinking hole. The bottom abuts against the opposite side surface of the nipple nipple. As a result, the force introduced from the side wall of the cap into the side surface having the drinking hole is supported via the opposite side surface of the nipple at the bottom of the cap. Thus, the side wall bears with a particularly high pressure force on the edge region of the drinking hole, so that there is a very good seal between this edge region and the side wall. The orientation of the nipple nipple on the corner region between the side wall and the bottom of the cap can be achieved in that the teat already aligned in the unloaded state acute angle to the central axis of the mounting edge of the nipple carrier Saugernippel Has. In a teat with nipple arranged in the unloaded state on the central axis, it can be achieved that the nipple is forced by the patch cap in an acute-angled orientation to the mounting edge. Due to the tilted nipple nipple, the free end of the nipple is pressed with attached cap between the bottom and side wall and the drinking hole is securely sealed.

Das Trinkloch kann als kreisrundes Loch oder schlitzförmig ausgeführt sein. Bevorzugt hat der Trinksauger nur ein einziges Trinkloch. Er kann aber auch mehrere Trinklöcher aufweisen, die zugleich in der beschriebenen Weise abgedichtet werden.The drinking hole can be designed as a circular hole or slit-shaped. Preferably, the teat has only a single drinking hole. But he may also have several drinking holes, which are sealed at the same time in the manner described.

Das freie Ende des Saugernippels kann verschieden ausgestaltet sein. Gemäß einer Ausgestaltung ist der Saugernippel an der das Trinkloch aufweisenden Seitenfläche mit einem verhältnismäßig großen oder kleinen Krümmungsradius nach außen gewölbt und an der gegenüberliegenden Außenseite annähernd flach oder leicht bzw. mit großem Krümmungsradius konkav gewölbt und weist dazwischen einen verhältnismäßig kleinen Übergangsradius auf. Gemäß einer weiteren Ausgestaltung ist das Trinkloch in einer von der Zentralachse des Befestigungsrandes abgewandten Seitenfläche des Saugernippels angeordnet.The free end of the nipple nipple can be configured differently. According to one embodiment, the nipple on the side surface having the drinking hole with a relatively large or small radius of curvature arched outwards and curved concave on the opposite outside approximately flat or slightly or with a large radius of curvature and has a relatively small transition radius therebetween. According to a further embodiment, the drinking hole is arranged in a side surface of the nipple nipple facing away from the central axis of the fastening edge.

Gemäß einer weiteren Ausgestaltung, die zu einer besonders gut abdichtenden Anlage der Abdeckkappe am Trinkloch führt, weist die Abdeckkappe eine kegelförmige Außenwand und/oder einen kalottenförmigen Boden auf. Der kalottenförmige Boden ist bevorzugt nach innen gewölbt, d.h. in das Innere der Abdeckkappe ein. Bevorzugt ist der Übergang zwischen Boden und Seitenwand der Abdeckkappe ausgerundet. Die Abdichtung ist besonders effektiv, wenn diese Abdeckkappe mit einem wie vorstehend beschrieben am freien Ende ausgestalteten Saugernippel zusammenwirkt.According to a further embodiment, which leads to a particularly good sealing installation of the cap on the drinking hole, the cap on a conical outer wall and / or a dome-shaped bottom. The dome-shaped bottom is preferably curved inward, ie in the interior of the cap. Preferably, the transition between the bottom and side wall of the cap is rounded. The seal is especially effective when this Cover cooperates with a nipple designed as described above at the free end.

Die Abdeckkappe ist lösbar am Schraubring gehalten. Beispielsweise können Abdeckkappe und Schraubring aneinander angepasste Sitzflächen aufweisen, die einen Klemmsitz bzw. einen reibschlüssigen Sitz der Abdeckkappe auf dem Schraubring ermöglichen. Gemäß einer Ausgestaltung weisen Schraubring und Abdeckkappe zusammenwirkende Rastelemente zum Verrasten der Abdeckkappe an dem Schraubring auf.The cap is releasably held on the screw ring. For example, cap and screw ring may have matched seats, which allow a clamping fit or a frictional fit of the cap on the threaded ring. According to one embodiment, screw ring and cover have cooperating locking elements for locking the cap on the screw ring.

Gemäß einer weiteren Ausgestaltung, die zu einer besonders sicheren Abdichtung des Trinkloches an der Abdeckkappe führt, ist die Lochachse des Trinkloches etwa senkrecht zur Seitenwand der Abdeckkappe ausgerichtet. Infolgedessen liegt der Randbereich des Trinkloches gleichmäßig abdichtend an der Seitenwand der Abdeckkappe an.According to a further embodiment, which leads to a particularly secure sealing of the drinking hole on the cap, the hole axis of the drinking hole is aligned approximately perpendicular to the side wall of the cap. As a result, the edge region of the drinking hole is uniformly sealingly against the side wall of the cap.

Gemäß einer Ausgestaltung hat die das Trinkloch aufweisende Seitenfläche einen kleineren Krümmungsradius als die daran anliegende Innenseite der Seitenwand und/oder hat die gegenüberliegende Seitenfläche einen größeren Krümmungsradius als die dagegen drückende Innenseite des Bodens. Dies gilt für die Krümmungsradien in mindestens einer Schnittebene durch die Kontaktbereiche zwischen Saugernippe und Abdeckkappe. Beispielsweise gilt dies zumindest für die Krümmungsradien in einer vertikalen Schnittebene. Bevorzugt gilt dies für die Krümmungsradien in mehreren Schnittebenen, weiterhin bevorzugt für die Krümmungsradien in sämtlichen Schnittebenen. Hierdurch wird eine hohe Flächenpressung um das Trinkloch erzeugt und die Gegenkraft gezielt in die gegenüberliegende Seitenfläche des Trinksaugers eingeleitet.According to one embodiment, the side surface having the drinking hole has a smaller radius of curvature than the inner side of the side wall resting thereon and / or the opposite side surface has a greater radius of curvature than the inner side of the bottom which presses against it. This applies to the radii of curvature in at least one sectional plane through the contact areas between suction rib and cap. For example, this applies at least to the radii of curvature in a vertical sectional plane. This preferably applies to the radii of curvature in a plurality of sectional planes, furthermore preferably to the radii of curvature in all sectional planes. As a result, a high surface pressure is generated around the drinking hole and initiated the counterforce targeted in the opposite side surface of the teat.

Der Nippelträger des Trinksaugers kann unterschiedlich ausgestaltet sein. Gemäß einer Ausgestaltung ist er balgförmig ausgeführt, indem er beispielsweise angrenzend an den Befestigungsrand eine Taille und daran angrenzend eine Ausbauchung aufweist. Der Trinksauger kann auch mehrere aufeinanderfolgende Taillen und Ausbauchungen haben. Gemäß einer anderen Ausgestaltung ist der Nippelträger haubenförmig bzw. glockenförmig ausgeführt, so dass er sich ausgehend vom Nippelträger allmählich bis zu einem Scheitel verjüngt, auf dem der Saugernippel sitzt.The nipple carrier of the teat can be designed differently. According to one embodiment, it is designed bellows-shaped, for example by having adjacent to the attachment edge a waist and adjacent thereto a bulge. The teat may also have several consecutive waists and bulges. According to another embodiment, the nipple carrier is hood-shaped or bell-shaped, so that it gradually tapers from the nipple carrier to a vertex on which the nipple sits.

Gemäß einer weiteren Ausgestaltung weist der Nippelträger eine um die Zentralachse des Befestigungsrandes umlaufende Nut auf. Hier kann insbesondere einem haubenförmigen Nippelträger eine erhöhte Flexibilität verliehen werden.According to a further embodiment, the nipple carrier has a groove running around the central axis of the fastening edge. Here, in particular a hood-shaped nipple carrier increased flexibility can be imparted.

Gemäß einer weiteren Ausgestaltung weist der Trinksauger einen integrierten Sicherheitsfaden auf, der sich vom Befestigungsrand bis zum freien Ende des Saugernippels erstreckt. Hierdurch wird dem Trinksauger eine erhöhte Festigkeit verliehen. Trinksauger mit Sicherheitsfaden sind insbesondere bei Ausführung des Trinksaugers aus Silikonkautschuk vorteilhaft, da der Sicherheitsfaden ein Abreißen eines Teils des Trinksaugers verhindern kann.According to a further embodiment, the teat has an integrated security thread which extends from the attachment edge to the free end of the teat nipple. As a result, the teat is given an increased strength. Teat with safety thread are particularly advantageous in execution of the teat made of silicone rubber, since the security thread can prevent tearing of a portion of the teat.

Gemäß einer weiteren Ausgestaltung erstreckt sich der Sicherheitsfaden vom Befestigungsrand bis zum Trinkloch. Der Sicherheitsfaden kann formschlüssig und/oder kraftschlüssig und/oder stoffschlüssig mit dem Trinksauger verbunden sein. Ein formschlüssiges Verbinden ist beispielsweise durch teilweises oder vollständiges Einbetten des Sicherheitsfadens in das Material des Trinksaugers möglich. Ein vollständig eingebetteter Sicherheitsfaden ist allseitig vom Material des Trinksaugers umgeben. Eine kraftschlüssige Verbindung kann durch Einpressen des Sicherheitsfadens in eine Nut des Trinksaugers erzeugt werden. Bevorzugt ist eine stoffschlüssige Verbindung zwischen Sicherheitsfaden und Trinksauger, die durch Vernetzung beziehungsweise Verschmelzung der Kontaktbereiche von Sicherheitsfaden und Trinksauger erzielt werden kann. Eine weitere Möglichkeit der stoffschlüssigen Verbindung ist die Verklebung von Sicherheitsfaden und Trinksauger. Bevorzugt ist der Trinksauger aus einem Kunststoff, der mit dem Material des Sicherheitsfadens und/oder des Schraubringes verschmelzbar beziehungsweise vernetzbar ist. Bevorzugt ist der Trinksauger gegebenenfalls gemeinsam mit dem Sicherheitsfaden bzw. dem Schraubring im Mehrkomponenten-Spritzgießverfahren hergestellt.According to a further embodiment, the security thread extends from the attachment edge to the drinking hole. The security thread can be positively and / or non-positively and / or materially connected to the teat. A positive connection is possible, for example, by partially or completely embedding the security thread in the material of the teat. A completely embedded security thread is surrounded on all sides by the material of the teat. A non-positive connection can be generated by pressing the security thread into a groove of the teat. Is preferred a cohesive connection between security thread and teat, which can be achieved by networking or merging the contact areas of security thread and teat. Another possibility of cohesive connection is the bonding of security thread and teat. Preferably, the teat is made of a plastic, which is fusible or crosslinkable with the material of the security thread and / or the screw ring. Preferably, the teat is optionally made together with the security thread or the screw ring in multi-component injection molding.

Grundsätzlich können der Trinksauger und der Schraubring getrennt voneinander ausgeführt sein. Bei einer Ausgestaltung dieser Ausführungsart weist der Schraubring einen nach innen vorstehenden Ringflansch zum Andrücken des Befestigungsrandes an einen Öffnungsrand der Flaschenöffnung und eine zentrale Einsetzöffnung zum Einsetzen des Saugernippels und des Nippelträgers des Trinksaugers auf. Bei dieser Ausgestaltung wird der Trinksauger am Befestigungsrand zwischen Schraubring und Öffnungsrand der Flasche eingeklemmt.In principle, the teat and the screw ring can be carried out separately. In one embodiment of this embodiment, the screw ring has an inwardly projecting annular flange for pressing the fastening edge against an opening edge of the bottle opening and a central insertion opening for inserting the nipple nipple carrier and the nipple carrier of the teat. In this embodiment, the teat is clamped at the attachment edge between the screw ring and the opening edge of the bottle.

Gemäß einer anderen Ausgestaltung ist der Trinksauger am Befestigungsrand fest mit dem Schraubring verbunden. Ein einteilig mit dem Schraubring verbundener Trinksauger kann insbesondere im Mehrkomponenten-Spritzgießverfahren hergestellt werden. Der Trinksauger kann formschlüssig und/oder kraftschlüssig und/oder stoffschlüssig mit dem Schraubring verbunden sein. Eine formschlüssige Verbindung kann durch formschlüssiges Ineinandergreifen von Trinksauger und Schraubring erzielt werden. Eine kraftschlüssige Verbindung zwischen Trinksauger und Schraubring wird beispielsweise erreicht, indem Trinksauger und Schraubring aus verschiedenen Kunststoffen hergestellt werden, die nach dem Spritzgießen eine verschieden starke Schrumpfung aufweisen, wobei der stärker schrumpfende Teil den schwächer schrumpfenden Teil zumindest teilweise umschließt, so dass er den innen liegenden Teil einklemmt. Ferner können Trinksauger und Schraubring stoffschlüssig miteinander verbunden werden, indem der Kunststoff des Trinksaugers und der Kunststoff des Schraubringes so ausgewählt werden, dass sie in den Kontaktbereichen miteinander verschmelzen beziehungsweise vernetzen. Ferner ist eine stoffschlüssige Verbindung durch Verkleben möglich. Auf diese Weise kann eine sehr feste Verbindung zwischen Trinksauger und Schraubring hergestellt werden.According to another embodiment of the teat is firmly connected to the fastening edge on the mounting ring. A one-piece connected to the screw ring teat can be produced in particular in multi-component injection molding. The teat may be positively and / or non-positively and / or materially connected to the screw ring. A positive connection can be achieved by positive engagement of teat and screw ring. A frictional connection between teat and screw ring is achieved, for example, by drinking teat and screw ring are made of different plastics, which after injection molding a have different degrees of shrinkage, wherein the more shrinking part at least partially surrounds the weaker shrinking part, so that it clamps the inner part. Furthermore, teat and screw ring can be materially connected to each other by the plastic of the teat and the plastic of the screw ring are selected so that they merge together or crosslink in the contact areas. Furthermore, a cohesive connection by gluing is possible. In this way, a very strong connection between teat and screw ring can be made.

Gemäß einer weiteren vorteilhaften Ausgestaltung ist der Sicherheitsfaden fest mit dem Schraubring verbunden, so dass der Sicherheitsfaden an dem Schraubring fixiert ist. Vorteilhaft sind der Trinksauger aus einem weichen bzw. weichelastischen Material und der Schraubring und die Flasche aus einem steiferen Material hergestellt.According to a further advantageous embodiment of the security thread is firmly connected to the threaded ring, so that the security thread is fixed to the threaded ring. Advantageously, the teat from a soft or soft elastic material and the screw ring and the bottle are made of a stiffer material.

Für den Trinksauger kommen verschiedene weichelastische Materialien in Betracht. Beispielsweise kann ein Naturkautschuk oder ein synthetischer Kautschuk oder ein anderes Elastomer verwendet werden. Gemäß einer weiteren Ausgestaltung ist der weichelastische Kunststoff ein thermoplastisches Elastomer. Thermoplastische Elastomere können vorteilhaft durch Spritzgießen verarbeitet werden. Thermoplastische Elastomere können mehrphasige Kunststoffe sein, die gummielastisch formbare Molekülbereiche aufweisen, in die die Bereiche amorpher Thermoplaste eingebaut sind. Sie sind daher thermoplastisch verformbar und weisen gleichzeitig die gewünschten elastischen Eigenschaften auf.For the teat various soft elastic materials come into consideration. For example, a natural rubber or a synthetic rubber or other elastomer may be used. According to a further embodiment, the soft elastic plastic is a thermoplastic elastomer. Thermoplastic elastomers can advantageously be processed by injection molding. Thermoplastic elastomers can be multi-phase plastics having elastomeric moldable molecular domains incorporating the regions of amorphous thermoplastics. They are therefore thermoformable and at the same time have the desired elastic properties.

Der Sicherheitsfaden kann verschieden ausgeführt sein. Beispielsweise ist er ein textiler Faden aus mehreren miteinander verbunden beziehungsweise verdrehtenThe security thread can be designed differently. For example, it is a textile thread of several interconnected or twisted

Fasern oder ein Band oder ein Streifen. Bevorzugt ist das Band oder der Streifen eine Folie aus Kunststoff. Eine feste Verbindung zwischen Sicherheitsfaden und Schraubring kann formschlüssig und/oder kraftschlüssig und/oder stoffschlüssig sein. Zur formschlüssigen Verbindung kann der Sicherheitsfaden beispielsweise mit verdickten Enden im Material des Schraubringes verankert sein. Für eine kraftschlüssige Verbindung kann er mit den Enden in Aufnahmen des Schraubringes eingepresst sein. Für eine stoffschlüssige Verbindung kann er an mindestens einem Ende durch Vernetzen und/oder durch Verkleben mit dem Material des Schraubringes verbunden sein.Fibers or a ribbon or a strip. Preferably, the tape or strip is a plastic film. A firm connection between security thread and screw ring can be positive and / or non-positive and / or cohesive. For positive connection of the security thread can be anchored, for example, with thickened ends in the material of the screw ring. For a non-positive connection, it can be pressed with the ends in recordings of the screw ring. For a cohesive connection, it can be connected at least at one end by crosslinking and / or by gluing to the material of the screw ring.

Bevorzugt besteht der Sicherheitsfaden aus Kunststoff. Der Sicherheitsfaden kann insbesondere aus demselben Kunststoff wie der Schraubring sein, was insbesondere bevorzugt ist, wenn der Sicherheitsfaden einteilig mit dem Schraubring oder stoffschlüssig mit diesem verbunden ausgeführt ist. Beispielsweise besteht der Sicherheitsfaden aus Polypropylen.The security thread preferably consists of plastic. The security thread can in particular be made of the same plastic as the screw ring, which is particularly preferred when the security thread is made in one piece with the screw ring or materially connected thereto. For example, the security thread is made of polypropylene.

Bevorzugt ist der Trinksauger zusätzlich mit einem Ventil - z.B. Schlitzventil - versehen, durch das Luft nachströmen kann, um einen Druckausgleich zu bewirken.Preferably, the teat is additionally provided with a valve - e.g. Slit valve - provided, can flow through the air to effect a pressure equalization.

Die Erfindung wird nachfolgend anhand der anliegenden Zeichnungen von Ausführungsbeispielen näher erläutert.The invention will be explained in more detail with reference to the accompanying drawings of exemplary embodiments.

Bei der nachfolgenden Erläuterung verschiedener Ausführungsbeispiele sind entsprechende Teile mit denselben Bezugsziffern versehen, wobei die Bezugsziffern weiterer Ausführungsbeispiele mit Anstrichen gekennzeichnet sind.In the following explanation of various embodiments, corresponding parts are provided with the same reference numerals, wherein the reference numerals of further embodiments are marked with paints.

Die Anordnung von Fig. 1 weist einen Trinksauger 1 mit einem balgförmigen Nippelträger 2 mit einer Taille 3, einer Ausbauchung 4 und einem kreisringschreibenförmigen Befestigungsrand 5 auf. Oben trägt der Nippelträger 2 einen Saugernippel 6, der einen Nippelkopf 7 und einen etwas eingeschnürten Hals 8 aufweist. Der Saugernippel 6 ist spitzwinklig zur Zentralachse 9 des Befestigungsrandes 5 geneigt, wobei die Neigungsachse mit 10 bezeichnet ist. Der Saugernippel 6 weist diese Neigung bezüglich der Zentralachse 9 im unbelasteten Zustand auf.The arrangement of Fig. 1 has a teat 1 with a bellows-shaped nipple carrier 2 with a waist 3, a bulge 4 and a circular ring-shaped fastening edge 5 on. At the top, the nipple carrier 2 carries a nipple 6, which has a nipple head 7 and a somewhat constricted neck 8 having. The nipple nipple 6 is inclined at an acute angle to the central axis 9 of the fastening edge 5, wherein the inclination axis is denoted by 10. The nipple 6 has this inclination with respect to the central axis 9 in the unloaded state.

Die schräg geneigte Ausrichtung des Saugernippels 6 kann bei der Verabreichung von Nahrung Vorteile aufweisen.The obliquely inclined orientation of the nipple nipple 6 may have advantages in the administration of food.

Der Saugernippel 6 ist orthodontisch geformt. Eine von der Zentralachse 9 abgewandte Seitenfläche 11 des Nippelkopfes 7 ist leicht konvex gekrümmt beziehungsweise weist einen großen Krümmungsradius auf. Eine der Zentralachse 9 zugewandte Seitenfläche 12 des Nippelkopfes 7 ist leicht konkav gekrümmt. Die Übergangsbereiche zwischen den beiden vorgenannten Seitenflächen 11, 12 sind stärker konvex gekrümmt beziehungsweise weisen einen geringeren Krümmungsradius als die abgewandte Seitenfläche 11 auf.The nipple 6 is formed orthodontically. A side surface 11 of the nipple head 7 facing away from the central axis 9 is slightly convexly curved or has a large radius of curvature. One of the central axis 9 facing side surface 12 of the nipple head 7 is slightly concave curved. The transition areas between the two aforementioned side surfaces 11, 12 are more convexly curved or have a smaller radius of curvature than the opposite side surface 11.

In der abgewandten Seitenfläche 11 ist ein Trinkloch 13 vorhanden, das einen Hohlraum 14 im Inneren des Trinksaugers 1 mit der Umgebung verbindet.In the opposite side surface 11, a drinking hole 13 is present, which connects a cavity 14 in the interior of the teat 1 with the environment.

Der Nippelträger 2 hat an einer Seite ein Ventil 15, durch das der Hohlraum 14 mit der Umgebung verbindbar ist. Das Ventil 15 öffnet, wenn im Hohlraum 14 ein Unterdruck herrscht. Es ist bevorzugt als Schlitzventil ausgeführt.The nipple carrier 2 has on one side a valve 15, through which the cavity 14 is connectable to the environment. The valve 15 opens when there is a negative pressure in the cavity 14. It is preferably designed as a slit valve.

Ferner weist die Anordnung einen Schraubring 16 mit einem leicht konischen Mantel 17 und einem Innengewinde 18 zum Aufschrauben auf ein entsprechendes Außengewinde einer Flasche (nicht gezeigt) auf. Der Schraubring 16 kann mit einem Standardgewinde versehen sein, damit er auf verbreitete Flaschen passt.Furthermore, the arrangement has a threaded ring 16 with a slightly conical jacket 17 and an internal thread 18 for screwing onto a corresponding external thread of a bottle (not shown). The screw ring 16 may be provided with a standard thread to fit common bottles.

Der Schraubring 16 weist oben am Mantel 17 einen nach innen vorstehenden kreisringscheibenformigen Ringflansch 19 auf. Der Ringflansch 19 begrenzt eine Einsetzöffnung 20. In die Einsetzöffnung 20 ist der Trinksauger 1 mit dem Saugernippel 6 und dem Nippelträger 2 eingesetzt, wobei die Taille 3 genau innerhalb der Einsetzöffnung 20 angeordnet. Dabei befindet sich der Befestigungsrand 5 unterhalb des Ringflansches 19, so dass er von dem Ringflansch 19 gegen einen Öffnungsrand einer Flaschenöffnung einer Flasche gedrückt wird, wenn der Schraubring 16 auf das Außengewinde der Flasche aufgeschraubt wird.The screw ring 16 has on top of the jacket 17 on an inwardly projecting annular flange annular flange 19. The annular flange 19 defines an insertion opening 20. Into the insertion opening 20 of the teat 1 with the nipple nipple 6 and the nipple carrier 2 is inserted, wherein the waist 3 is arranged exactly within the insertion opening 20. In this case, the fastening edge 5 is below the annular flange 19, so that it is pressed by the annular flange 19 against an opening edge of a bottle opening of a bottle when the screw ring 16 is screwed onto the external thread of the bottle.

Der Schraubring 16 ist am Außenumfang mit einer umlaufenden Rastnut 21 versehen. Ferner umfasst die Anordnung eine Abdeckkappe 22, die eine leicht konische Seitenwand 23 aufweist, die am unteren Rand einen nach innen vorstehenden Rastwulst 24 hat, der in die Rastnut 21 des Schraubringes 16 einschnappbar ist.The screw ring 16 is provided on the outer circumference with a circumferential latching groove 21. Further, the arrangement comprises a cap 22, which has a slightly conical side wall 23 which has an inwardly projecting latching bead 24 at the lower edge, which can be snapped into the latching groove 21 of the screw ring 16.

Die Abdeckkappe 22 hat einen nach innen gewölbten, kalottenförmigen Boden 25. Der Übergangsbereich des kalottenförmigen Bodens 25 zur konischen Seitenwand 23 ist ausgerundet. Der kalottenförmige Boden ist symmetrisch bezüglich der Zentralachse 9. Die Ausrundung läuft um die Zentralachse 9 um.The cap 22 has an inwardly curved, dome-shaped bottom 25. The transition region of the dome-shaped bottom 25 to the conical side wall 23 is rounded. The dome-shaped bottom is symmetrical with respect to the central axis 9. The fillet runs around the central axis 9.

Wenn die Abdeckkappe 22 auf den Schraubring 16 geschnappt ist, drückt der kalottenförmige Boden 25 gegen die der Zentralachse 9 zugewandte Seitenfläche 12 des Nippelkopfes 7 und die Seitenwand 23 gegen die abgewandte Seitenfläche 11. Der Nippelkopf 7 wird somit zwischen dem Boden 25 und der Seitenwand 23 eingezwängt. Dabei ist der Nippelkopf 7 im Scheitelbereich in der Ausrundung zwischen kalottenförmigem Boden 25 und konischer Seitenwand 23 der Abdeckkappe 22 gehalten. Gemäß Fig. 1 stimmen die Innenkontur der Ausrundung der Abdeckkappe 22 und die Außenkontur des Scheitelbereiches des Nippelkopfes 7 etwa überein, so dass diese Bereiche aneinander anliegen. Das Trinkloch 13 ist so im Nippelkopf 7 angeordnet, dass es etwa senkrecht auf die Seitenwand 23 ausgerichtet ist und ein Randbereich um das Trinkloch 13 abdichtend gegen die Seitenwand 23 gepresst wird.When the cap 22 is snapped onto the screw ring 16, the dome-shaped bottom 25 presses against the central axis 9 facing side surface 12 of the nipple head 7 and the side wall 23 against the opposite side surface 11. The nipple head 7 is thus between the bottom 25 and the side wall 23rd constrained. In this case, the nipple head 7 is held in the apex region in the fillet between calotte-shaped bottom 25 and conical side wall 23 of the cap 22. According to Fig. 1 the inner contour of the rounding of the cap 22 and the outer contour of the apex area of the nipple head 7 approximately coincide, so that these areas abut each other. The drinking hole 13 is arranged in the nipple head 7, that it is aligned approximately perpendicular to the side wall 23 and an edge region around the drinking hole 13 is sealingly pressed against the side wall 23.

Gemäß Fig. 2 hat in der vertikalen Schnittebene die Seitenfläche 11 am Trinkloch 13 einen kleineren Krümmungsradius als die Seitenwand 23, um eine definierte Pressfläche um das Trinkloch 13 zu erzeugen. Ferner hat die Seitenfläche 12 im Bereich des Kontaktes mit dem Boden 25 einen größeren Krümmungsradius als der Boden 25, um einen definierten Druck auf die Seitenfläche 12 gegenüber dem Trinkloch 13 zu gewährleisten.According to Fig. 2 In the vertical sectional plane, the side surface 11 at the drinking hole 13 has a smaller radius of curvature than the side wall 23 to produce a defined pressing surface around the drinking hole 13. Further, the side surface 12 in the region of contact with the bottom 25 has a greater radius of curvature than the bottom 25 in order to ensure a defined pressure on the side surface 12 opposite the drinking hole 13.

Somit fängt die Abdeckkappe 22 die Geometrie des Nippelkopfes 7 ein und presst sie zum Abdichten in die obere Ecke der Abdeckkappe 22.Thus, the cap 22 captures the geometry of the nipple head 7 and presses it to seal in the upper corner of the cap 22nd

Die Ausführung von Fig. 3 unterscheidet sich von der vorgenannten insbesondere darin, dass an den Schraubring 16' der Trinksauger 1' angespritzt ist. Der Befestigungsrand 5' des Trinksaugers 1 ist mit dem oberen Rand 26' des Schraubringes 16' verbunden. Der Schraubring 16' besteht beispielsweise aus Polypropylen und der Trinksauger 1' aus einem thermoplastischen Elastomer (z.B. auf Polypropylenbasis), das mit dem Material des Schraubringes 16' vernetzt ist.The execution of Fig. 3 differs from the aforementioned in particular in that the teat 1 'is molded onto the threaded ring 16'. The fastening edge 5 'of the teat 1 is connected to the upper edge 26' of the threaded ring 16 '. The screw ring 16 'consists for example of polypropylene and the teat 1' made of a thermoplastic elastomer (eg polypropylene-based), which is crosslinked with the material of the threaded ring 16 '.

Ferner hat der Nippelträger 2' des einteilig mit dem Schraubring 16' ausgebildeten Trinksaugers 1' eine haubenartige Form.Further, the nipple carrier 2 'of the one-piece with the screw ring 16' formed teat 1 'has a hood-like shape.

Der Saugernippel 6' und das Trinkloch 13' sowie die Abdeckkappe 22' sind so ausgeführt wie bei dem vorangegangenen Ausführungsbeispiel. Insbesondere ist der Saugernippel 6' im unbelasteten Zustand des Trinksaugers 1' zur Zentralachse 9' geneigt.The nipple 6 'and the drinking hole 13' and the cap 22 'are designed as in the previous embodiment. In particular, the Nipple nipple 6 'in the unloaded state of the teat 1' to the central axis 9 'inclined.

Auch bei dieser Anordnung wird durch Aufschnappen der Abdeckkappe 22' auf den Nippelkopf 7' an der Ecke zwischen Boden 25 und Seitenwand 23 eingepresst und das Trinkloch 13 abgedichtet.Also in this arrangement is pressed by snapping the cap 22 'on the nipple head 7' at the corner between the bottom 25 and side wall 23 and the drinking hole 13 is sealed.

Das Ausführungsbeispiel von Fig. 4 bis 6 unterscheidet sich von dem Ausführungsbeispiel von Fig. 2 insbesondere dadurch, dass der an den Schraubring 16" angespritzte Trinksauger 1" aus weichelastischem Material im unverformten Zustand mit dem Saugernippel 6" auf der Zentralachse 9" des Befestigungsrandes 5" ausgerichtet ist. Der Trinksauger 1" weist somit im unverformten Zustand die übliche, gerade gestreckte Ausrichtung auf, an die viele Benutzer gewöhnt sind.The embodiment of 4 to 6 differs from the embodiment of Fig. 2 in particular in that the teat 1 "of soft-elastic material molded onto the screw ring 16 is aligned with the teat nipple 6" on the central axis 9 "of the fastening edge 5" in the undeformed state. The teat 1 "thus has the usual, straight shape in the undeformed state stretched orientation, which many users are used to.

Der Nippelträger 2" weist eine umlaufende Nut 29" bzw. Entlastungsrille auf.The nipple carrier 2 "has a circumferential groove 29" or relief groove.

Ferner ist in den Trinksauger 1" ein Sicherheitsfaden 27" eingebettet, der auf der einen Seite des Trinksaugers 1" vom oberen Rand 26" des Schraubringes 16" aus durch den Nippelträger 2" und den Saugernippel 6" bis zum Trinkloch 13" und vom Trinkloch 13" aus auf der gegenüberliegenden Seite des Trinksaugers 1" durch den Saugernippel 6" und den Nippelträger 2" bis zum Schraubring 16" verläuft. Der Sicherheitsfaden 27" ist an den beiden Enden fest mit dem Schraubring 16" verbunden. Der Sicherheitsfaden 16" besteht aus einem flexiblen Material, so dass er Verformungen des Trinksaugers 1" mitmacht.Further, in the teat 1 "a security thread 27" embedded on one side of the teat 1 "from the upper edge 26" of the ring nut 16 "from the nipple carrier 2" and the nipple 6 "to the drinking hole 13" and the drinking hole 13 "extends from the opposite side of the teat 1" through the teat nipple 6 "and the nipple carrier 2" to the threaded ring 16. "The security thread 27" is firmly connected at the two ends to the threaded ring 16 " made of a flexible material so that it participates in deformations of the teat 1 ".

Im Bereich des Trinkloches 13" hat der Sicherheitsfaden 27" eine Aufweitung 28", um die erforderliche Festigkeit auch dort zur Verfügung zu stellen.In the area of the drinking hole 13 ", the security thread 27" has a widening 28 "in order to provide the required strength there as well.

Bevorzugt sind Trinksauger 1", Schraubring 16" und Sicherheitsfaden 27" aus Materialien, die in den Kontaktbereichen miteinander verschmelzen beziehungsweise vernetzen. Gemäß Fig. 6 ist der Sicherheitsfaden 27" an der Außenseite mit der Innenseite des Trinksaugers 1" vernetzt.Preferred are teat 1 ", screw ring 16" and security thread 27 "of materials that merge together or crosslink in the contact areas Fig. 6 is the security thread 27 "on the outside with the inside of the teat 1" networked.

Beim Aufsetzen einer Abdeckkappe 22" gleitet der Nippelkopf 7" dieser Ausführung an dem innen gewölbten Boden 25" in den Randbereich, so dass sich die Seitenfläche 11 " mit dem Trinkloch 13" abdichtend an die Seitenwand 23" der Abdeckkappe 22" anlegt. Das Schwenken des Saugernippels 6" bezüglich der Zentralachse 9" wird durch die Nut 29" erleichtert.When placing a cap 22 "of the nipple head 7" slides this embodiment of the inner curved bottom 25 "in the edge region, so that the side surface 11" with the drinking hole 13 "sealingly against the side wall 23" of the cap 22 "rests the nipple nipple 6 "with respect to the central axis 9" is facilitated by the groove 29 ".
