Description

Die Erfindung bezieht sich auf einen Trinksauger insbesondere für Säuglinge und Kleinkinder.The invention relates to a teat especially for infants and toddlers.

Trinksauger werden zur Verabreichung von Milch und anderer flüssiger Nahrung insbesondere an Säuglinge und Kleinkinder verwendet. Trinksauger haben einen hohlen Saugernippel mit einer Durchtrittsöffnung für flüssige Nahrung. Der Saugernippel ist unten einteilig mit einer hohlen Saugertülle verbunden. Die Saugertülle weist unten einen kreisringförmigen Saugerflansch auf. Der Querschnitt des Saugernippels ist auf den Mund des Kindes abgestimmt. Im Bereich der Saugertülle erweitert sich der Querschnitt zum Saugerflansch hin bis auf den Querschnitt des Befestigungsrandes einer Trinkflasche. Mittels eines Befestigungsringes wird der Trinksauger am Befestigungsrand der Trinkflasche befestigt. Der Befestigungsring hat einen zylindrischen Mantel mit Befestigungsmitteln zum Befestigen an Befestigungsmitteln einer Trinkflasche. Die Befestigungsmittel sind vielfach Gewinde am Innenumfang des Mantels und am Außenumfang der Trinkflasche. Ferner hat der Befestigungsring einen nach innen vorstehenden, kreisringscheibenförmigen Ringflansch, der den Saugerflansch übergreift und gegen den Befestigungsrand der Trinkflasche presst. Beim Saugen entsteht ein Unterdruck in der Trinkflasche, der die Flüssigkeitsentnahme erschwert. Durch den Unterdruck kann der Trinksauger kollabieren, sodass der Saugernippel in die Trinkflasche einschlüpft. Um dies zu vermeiden, weisen Trinksauger ein Belüftungsventil auf. Das Belüftungsventil öffnet, wenn ein gewisser Unterdruck in der Trinkflasche herrscht. Hierdurch wird ein Druckausgleich mit der Umgebung erreicht.Teats are used to administer milk and other liquid foods, especially to infants and toddlers. Teats have a hollow nipple with a passage for liquid food. The nipple nipple is integrally connected at the bottom with a hollow suction nozzle. The Saugertülle has an annular Saugerflansch below. The cross-section of the nipple nipple is matched to the child's mouth. In the area of the suction grommet, the cross-section to the suction flange widens up to the cross-section of the attachment edge of a drinking bottle. By means of a fastening ring of the teat is attached to the mounting edge of the bottle. The mounting ring has a cylindrical shell with fastening means for attachment to fasteners of a bottle. The fasteners are often threaded on the inner circumference of the shell and the outer circumference of the bottle. Further, the mounting ring has an inwardly projecting annular disc-shaped annular flange which engages over the Saugerflansch and pressed against the mounting edge of the bottle. When vacuuming creates a negative pressure in the bottle, which makes it difficult to remove liquid. Due to the negative pressure, the teat can collapse, so that the nipple nipples into the bottle. To avoid this, have teat on a vent valve. The ventilation valve opens when there is a certain negative pressure in the drinking bottle. As a result, a pressure equalization with the environment is achieved.

Die DE 197 39 911 C5 beschreibt einen Trinksauger der vorbeschriebenen Art und die Befestigung des Trinksaugers mittels Schraubring an einer Trinkflasche. Bei diesem Trinksauger ist das Belüftungsventil ein Schlitzventil, das in einer Vertiefung in einer Seite der Tülle angeordnet ist.The DE 197 39 911 C5 describes a teat of the type described above and the attachment of the teat by means of screw ring on a bottle. at This teat is the vent valve is a slit valve, which is arranged in a recess in one side of the spout.

In der WO 2009/087077 A1 ist ein Trinksauger mit mehreren Trinkschlitzen beschrieben, die an den Seiten eines gedachten Vieleckes angeordnet sind. Das Belüftungsventil dieses Trinksaugers ist ein in einer Vertiefung angeordnetes Schlitzventil. Der Trinksauger ist aus weichelastischem Material hergestellt. Gemäß einer Ausgestaltung ist dieses Naturkautschuk oder Silikon oder ein thermoplastisches Elastomer (TPE). Der Trinksauger kann beispielsweise durch Tauchen eines Formkörpers in einer Latexsuspension oder durch Spritzgießen und nachfolgendes Einarbeiten der Schlitze mittels Messer hergestellt werden.In the WO 2009/087077 A1 is a teat with several drinking slits described, which are arranged on the sides of an imaginary polygon. The vent valve of this teat is a slot valve arranged in a recess. The teat is made of soft elastic material. In one embodiment, this is natural rubber or silicone or a thermoplastic elastomer (TPE). The teat can be prepared for example by dipping a shaped body in a latex suspension or by injection molding and subsequent incorporation of the slots by means of knives.

Die DE 299 06 849 U1 beschreibt einen weiteren Trinksauger mit einem Belüftungsventil in einer Vertiefung an der Seite der Tülle. Die Vertiefung weist zwar im Wesentlichen ebenflächige und einander gegenüberliegende Seitenwände auf, die im Eintiefungsgrund über einen schmalen Abschnitt in der Wandstärke miteinander verbunden sind. Nach Aufbrechen des Abschnittes mittels eines Schraubenziehers, einer Gabel oder dergleichen sind die Seitenwände von der Flüssigkeit in der Trinkflasche aneinanderdrückbar.The DE 299 06 849 U1 describes another teat with a vent valve in a recess on the side of the spout. Although the recess has substantially planar and opposing side walls, which are connected to each other in Eintiefungsgrund a narrow section in the wall thickness. After breaking the section by means of a screwdriver, a fork or the like, the side walls of the liquid in the drinking bottle are pressed against each other.

Die bekannten Trinksauger-Schlitzventile sind in der Herstellung aufwendig, da sie in einem zusätzlichen Herstellungsschritt mit dem Schlitz versehen werden müssen. Nachteilig ist zudem, dass die durch den Schlitz begrenzten Dichtlippen mit nur geringer Pressung aneinanderliegen, sodass das Lippenventil bereits beim Anlegen des Unterdruckes öffnet, der geringer sein kann, als der Unterdruck, den das Kind beim Stillen aufbringt.The known teat slit valves are expensive to manufacture, since they must be provided with the slot in an additional manufacturing step. Another disadvantage is that the limited by the slot sealing lips abut each other with little pressure, so that the lip valve already opens when applying the negative pressure, which may be less than the negative pressure applied by the child when breastfeeding.

Ferner bekannt sind Trinksauger mit einem Belüftungsventil zwischen Saugerflansch und Schraubring. Die DE 10 2005 006 768 A1 offenbart einen derartigen Trinksauger, der im Saugerflansch eine Ventilöffnung aufweist, die sich in Richtung zum Ringflansch des Schraubringes verjüngt. Der Saugerflansch trägt an der Oberseite eine ringförmige Erhebung, die in eine Nut in einer umlaufenden unteren Bodenfläche des Schraubringes eingreift. Die Saugertülle weist in der Außenseite eine Vertiefung auf, die bis zum Saugerflansch reicht und einen Entlüftungskanal bildet. Der äußere Randbereich des Saugerflansches ist zwischen Befestigungsrand und Ringflansch eingeklemmt. Sofern in der Trinkflasche ein Unterdruck herrscht, kann sich der innere Teil des Saugerflansches nach unten bewegen, sodass sich die Erhebung von der Basis der Nut entfernt. Infolgedessen kann durch den Entlüftungskanal, den Spalt zwischen Ringflansch und Saugerflansch und die Ventilöffnung ein Druckausgleich erfolgen.Also known are teat with a vent valve between Saugerflansch and screw ring. The DE 10 2005 006 768 A1 discloses such a teat, which has a valve opening in the suction flange, which tapers in the direction of the annular flange of the screw ring. The Saugerflansch carries at the top of an annular projection which engages in a groove in a circumferential lower bottom surface of the screw ring. The suction grommet has a recess in the outside, which extends to the Saugerflansch and forms a vent channel. The outer edge region of the Saugerflansches is clamped between the mounting edge and annular flange. If there is a negative pressure in the drinking bottle, the inner part of the nipple flange can move downwards, so that the elevation moves away from the base of the groove. As a result, can be done by the vent channel, the gap between the annular flange and Saugerflansch and the valve opening, a pressure equalization.

Diese Konstruktion ist in der Herstellung aufwendig und schwer zu reinigen. Außerdem kann eine auf den Trinksauger wirkende Axialkraft das Belüftungsventil öffnen, wodurch der Aufbau eines Unterdruckes in der Trinkflasche verhindert wird.This construction is expensive to manufacture and difficult to clean. In addition, acting on the teat axial force can open the vent valve, whereby the build-up of a negative pressure in the bottle is prevented.

Eine ähnliche Konstruktion ist aus der US 2007/0102388 bekannt.A similar construction is from the US 2007/0102388 known.

Trinksauger mit Lippenventilen an der Unterseite eines Saugerflansches sind aus der US 2005/0252875 A1 , WO 2006/103379 A1 , DE 202 04 357 U1 und US 2003/0106872 A1 bekannt. Diese Trinksauger werden im Spritzgießverfahren hergestellt. Herstellungsbedingt liegen die Dichtlippen ohne Vorspannung aneinander an, sodass sie durch einen Unterdruck leicht geöffnet werden können. Der Druckausgleich erfolgt bei geöffnetem Lippenventil durch einen Spalt zwischen der Oberseite des Saugerflansches und der Unterseite des Ringflansches. Wenn Flüssigkeit an den Seitenflächen des Belüftungsventils anliegt, werden diese zusammengedrückt und der Flüssigkeitsaustritt verhindert. Die beiden letztgenannten Druckschriften beschreiben Trinksauger, bei denen das Lippenventil in die Wand des Saugerflansches integriert ist.Teats with lip valves on the bottom of a Saugerflansches are from the US 2005/0252875 A1 . WO 2006/103379 A1 . DE 202 04 357 U1 and US 2003/0106872 A1 known. These teat cups are manufactured by injection molding. Due to the manufacturing process, the sealing lips lie against each other without prestressing, so that they can be easily opened by a negative pressure. The pressure equalization takes place with the lip valve open through a gap between the upper side of the suction flange and the underside of the annular flange. If fluid is applied to the side surfaces of the vent valve, they will be compressed and the liquid leakage prevented. The latter two publications describe teat, in which the lip valve is integrated into the wall of Saugerflansches.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, einen Trinksauger zu schaffen, der leicht herstellbar ist und es ermöglicht, den Öffnungsdruck des Belüftungsventils vorzugeben.Based on this, the present invention seeks to provide a teat, which is easy to manufacture and makes it possible to specify the opening pressure of the ventilation valve.

Die Aufgabe wird durch einen Trinksauger mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen des Trinksaugers sind in Unteransprüchen angegeben.The object is achieved by a teat with the features of claim 1. Advantageous embodiments of the teat are given in subclaims.

Der erfindungsgemäße Trinksauger insbesondere für Säuglinge und Kleinkinder hat

  • einen hohlen Saugernippel mit mindestens einer Durchtrittsöffnung für flüssige Nahrung, die unten mit einer hohlen Saugertülle verbunden ist, die unten mit einem im Wesentlichen kreisringscheibenförmigen Saugerflansch verbunden ist, der zum Befestigen am Befestigungsrand einer Trinkflasche dient, wobei die Trinkflasche mittels eines Befestigungsringes mit der Saugertülle verbindbar ist, der mit einem zylindrischen Mantel mit Befestigungsmitteln zum Befestigen an weiteren Befestigungsmitteln der Trinkflasche und einem den Saugerflansch übergreifenden, kreisringscheibenförmigen Ringflansch versehen ist,
  • einen vom Saugerflansch nach unten oder oben oder von der Saugertülle oberhalb des Saugerflansches nach außen in den Raum für die Platzierung des Ringflansches vorstehenden Kontaktbereich,
dadurch gekennzeichnet, dass
  • ein Lippenventil, das geöffnet ist, wenn der Saugerflansch nicht mittels eines Befestigungsringes an einer Trinkflasche befestigt ist, in einem Verformungsbereich neben dem Kontaktbereich angeordnet ist, sodass bei Befestigung des Saugerflansches mittels des Befestigungsringes an einer Trinkflasche die durch Andrücken des Befestigungsringes an den Kontaktbereich bewirkte Verformung von Saugerflansch und/ oder Saugertülle das Lippenventil schließt.
The teat according to the invention especially for infants and toddlers has
  • a hollow nipple with at least one passage for liquid food, which is connected at the bottom with a hollow suction nozzle, which is connected at the bottom with a substantially annular disc-shaped Saugerflansch, which serves for attachment to the mounting edge of a drinking bottle, the bottle by means of a fastening ring with the Saugertülle connectable is, which is provided with a cylindrical jacket with fastening means for fastening to further fastening means of the drinking bottle and a Saugerflansch cross-annular disc-shaped annular flange,
  • a contact area projecting from the suction flange downwards or upwards or from the suction nozzle above the suction flange outwards into the space for the placement of the annular flange,
characterized in that
  • a lip valve, which is open when the Saugerflansch is not attached by means of a mounting ring on a drinking bottle, is arranged in a deformation region next to the contact area, so when fastening the Saugerflansches by means of the mounting ring on a drinking bottle caused by pressing the mounting ring to the contact area deformation Suction cup and / or suction grommet closes the lip valve.

Der erfindungsgemäße Trinksauger weist ein Lippenventil auf, das im Saugerflansch oder in der Saugertülle angeordnet ist. Der Trinksauger wird so hergestellt, dass das Lippenventil geöffnet ist. Das Lippenventil ist in einem Verformungsbereich neben einem Kontaktbereich des Trinksaugers angeordnet. Der Kontaktbereich steht vom Saugerflansch nach unten oder oben oder oberhalb des Saugerflansches von der Saugertülle nach außen vor. Infolgedessen wird er bei Befestigung des Trinksaugers an einer Trinkflasche vom Befestigungsring in besonderem Maße verformt. Die Verformung des Kontaktbereiches wirkt sich auf den angrenzenden Verformungsbereich des Trinksaugers aus, in dem das Lippenventil angeordnet ist. Durch die Verformung des Verformungsbereichs wird das Lippenventil geschlossen. Die Höhe der Pressung zwischen den Dichtlippen kann durch die Gestaltung des Verformungsbereiches und des Lippenventils gesteuert werden. Infolgedessen ist es möglich, einen bestimmten Öffnungsdruck zu erreichen. Der Trinksauger kann so gestaltet werden, dass der Öffnungsdruck unabhängig von einer axial auf den Trinksauger wirkenden Kraft ist. Der Trinksauger mit dem geöffneten Lippenventil ist leicht durch Spritzgießen herstellbar. Ein nachträgliches Einarbeiten eines Trinkschlitzes ist nicht erforderlich. Das geöffnete Lippenventil erleichtert ein vollständiges Reinigen des Trinksaugers nach der Benutzung.The teat according to the invention has a lip valve which is arranged in the suction flange or in the suction nozzle. The teat is made so that the lip valve is open. The lip valve is arranged in a deformation area next to a contact area of the teat. The contact area projects from the suction flange downwards or upwards or above the suction flange from the suction nozzle to the outside. As a result, it is deformed when attaching the teat to a bottle from the mounting ring in particular extent. The deformation of the contact region has an effect on the adjacent deformation region of the teat in which the lip valve is arranged. The deformation of the deformation area closes the lip valve. The amount of pressure between the sealing lips can be controlled by the design of the deformation area and the lip valve. As a result, it is possible to achieve a certain opening pressure. The teat can be designed so that the opening pressure is independent of an axially acting on the teat force. The teat with the open lip valve can be easily produced by injection molding. A subsequent incorporation of a drinking slit is not required. The opened lip valve facilitates full cleaning of the teat after use.

Gemäß einer Ausgestaltung ist das Lippenventil im Saugerflansch in einem Abstand vom äußeren Rand des Saugerflansches angeordnet. Der Saugerflansch ist am äußeren Rand zwischen dem Befestigungsrand und dem Ringflansch festlegbar. Das Lippenventil ist der Öffnung der Trinkflasche zugewandt. Durch einen Spalt zwischen Befestigungsring und Trinksauger kann die Umgebungsluft für einen Druckausgleich nachströmen.According to one embodiment, the lip valve is arranged in Saugerflansch at a distance from the outer edge of the Saugerflansches. The Saugerflansch is fixed to the outer edge between the mounting edge and the annular flange. The lip valve faces the opening of the drinking bottle. Through a gap between the mounting ring and teat, the ambient air can flow for a pressure equalization.

Gemäß einer weiteren Ausgestaltung steht das Lippenventil von der Unterseite des Saugerflansches vor. Das Lippenventil kann in die Öffnung der Trinkflasche eingreifen.According to a further embodiment, the lip valve projects from the underside of the suction flange. The lip valve can engage in the opening of the bottle.

Gemäß einer weiteren Ausgestaltung ist der Kontaktbereich eine Wölbung des unverformten Saugerflansches, in der das Lippenventil angeordnet ist, die zwischen Befestigungsrand und Ringflansch flachgedrückt ist, wenn der Saugerflansch mittels eines Befestigungsringes an der Trinkflasche montiert ist. Der Trinksauger wird mit geöffnetem Lippenventil im Bereich der Wölbung hergestellt. Wenn die Wölbung flachgedrückt ist, legen sich die Lippen des Lippenventils dichtend aneinander. Der Öffnungsdruck ist durch die Gestaltung der Wölbung und des Lippenventils steuerbar.According to a further embodiment, the contact area is a curvature of the undeformed Saugerflansches in which the lip valve is arranged, which is flattened between mounting edge and annular flange when the Saugerflansch is mounted by means of a mounting ring on the bottle. The teat is made with the lip valve open in the area of the curvature. When the arch is flattened, the lips of the lip valve seal against each other. The opening pressure is controllable by the design of the curvature and the lip valve.

Gemäß einer weiteren Ausgestaltung weist die Saugertülle oberhalb des Lippenventils eine radial zum Saugerflansch gerichtete Einbuchtung auf. Die Einbuchtung begünstigt die Herstellung des Trinksaugers mit dem Lippenventil in dem Saugerflansch mittels eines einfachen Spritzgießwerkzeuges, dessen Teile senkrecht zu einer einzigen Teilungsebene auseinanderziehbar sind. Außerdem kann die Einbuchtung für die Zufuhr von Umgebungsluft zum Lippenventil dienen.According to a further embodiment, the suction nozzle above the lip valve on a radially directed to the suction flange indentation. The indentation favors the production of the teat with the lip valve in the Saugerflansch means of a simple injection mold, the parts of which are pulled apart perpendicular to a single dividing plane. In addition, the indentation may be for the supply of ambient air to the lip valve.

Gemäß einer anderen Ausgestaltung ist das Lippenventil in der Saugertülle angeordnet und ist der Kontaktbereich eine Wölbung des unverformten Saugerflansches unterhalb des Lippenventils, die zwischen Befestigungsrand und Ringflansch flachgedrückt ist, wenn der Saugerflansch mittels eines Befestigungsringes an einer Trinkflasche montiert ist. Dieser Trinksauger wird ebenfalls mit einer Wölbung im unverformten Saugerflansch hergestellt und einem geöffneten Lippenventil. Das Lippenventil ist jedoch nicht im Saugerflansch, sondern oberhalb des Saugerflansches in der Saugertülle angeordnet. Wenn der Saugerflansch zwischen Befestigungsrand und Ringflansch eingeklemmt ist, wird die Wölbung flachgedrückt und durch diese Verformung schließt sich das Lippenventil. Die Pressung zwischen den Lippen des Lippenventils hängt von der Gestaltung der Wölbung und des Lippenventils ab und ist damit steuerbar. Für den Druckausgleich kann die Umgebungsluft direkt von der Seite der Saugertülle aus in das Lippenventil einströmen.According to another embodiment, the lip valve is arranged in the suction nozzle and the contact area is a curvature of the undeformed Saugerflansches below the lip valve, which is flattened between mounting edge and annular flange when the Saugerflansch is mounted by means of a mounting ring on a bottle. This teat is also made with a buckle in undeformed Saugerflansch and an open lip valve. However, the lip valve is not located in Saugerflansch, but above the Saugerflansches in the Saugertülle. If the suction flange is clamped between the fastening edge and the annular flange, the curvature is flattened and this deformation closes the lip valve. The pressure between the lips of the lip valve depends on the design of the curvature and the lip valve and is thus controllable. For pressure equalization, the ambient air can flow directly into the lip valve from the side of the suction nozzle.

Gemäß einer weiteren Ausgestaltung ist die Wölbung des unverformten Saugerflansches nach unten gerichtet. Wenn das Lippenventil von der Unterseite der Wölbung mit radial zum Saugerflansch gerichteten Lippen vorsteht, werden durch das Flachdrücken der Wölbung die Lippen geschlossen. Wenn das Lippenventil in der Saugertülle mit zu den dem Saugerflansch parallelen Lippen angeordnet ist, werden die Lippen ebenfalls durch Flachdrücken der Wölbung geschlossen.According to a further embodiment, the curvature of the undeformed Saugerflansches is directed downward. When the lip valve protrudes from the underside of the arch with lips directed radially to the nipple flange, the flattening of the camber closes the lips. When the lip valve in the suction grommet is arranged with the lips parallel to the suction flange, the lips are also closed by flattening the curvature.

Gemäß einer anderen Ausgestaltung ist das Lippenventil in der Saugertülle angeordnet und der Kontaktbereich ein neben dem Lippenventil nach außen vorstehender Wulst der Saugertülle, der in dem Raum angeordnet ist, den der Ringflansch des Schraubringes einnimmt, wenn der Schraubring den Saugerflansch an einer Trinkflasche fixiert. Dieser Trinksauger wird ebenfalls mit geöffnetem Lippenventil hergestellt. Wenn der Trinksauger mittels des Befestigungsringes an der Trinkflasche fixiert ist, drückt der Befestigungsring gegen den nach außen vorstehenden Wulst. Hierdurch wird das Schließen der Dichtlippen des Lippenventils bewirkt. Bei einem gegebenen Befestigungsring ist es durch Gestaltung des Wulstes möglich, die Pressung zwischen den Dichtlippen und den Öffnungsdruck zu steuern.According to another embodiment, the lip valve is arranged in the Saugertülle and the contact area adjacent to the lip valve outwardly projecting bead of the Saugertülle, which is arranged in the space occupied by the annular flange of the screw ring when the screw ring fixes the Saugerflansch on a drinking bottle. This teat is also made with the lip valve open. When the teat is fixed by means of the fastening ring on the drinking bottle, the fastening ring presses against the outwardly projecting bead. As a result, the closing of the sealing lips of the lip valve is effected. For a given mounting ring, by forming the bead, it is possible to control the pressure between the sealing lips and the opening pressure.

Gemäß einer Ausgestaltung des Trinksaugers, der ein Lippenventil in der Saugertülle aufweist, ist das Lippenventil radial bezüglich des Saugerflansches in die Saugertülle hineingerichtet. Bei dieser Ausgestaltung ist das Lippenventil im Sauger angeordnet und stört daher nicht bei der Benutzung.According to one embodiment of the teat, which has a lip valve in the suction nozzle, the lip valve is directed radially with respect to the Saugerflansches in the suction nozzle. In this embodiment, the lip valve is arranged in the teat and therefore does not interfere with use.

Gemäß einer weiteren Ausgestaltung weist die Saugertülle oberhalb des Saugerflansches eine Einschnürung auf. Die Einschnürung ermöglicht eine unverlierbare Vormontage des Befestigungsrings am Trinksauger und erleichtert damit die Handhabung. Außerdem deckt die Saugertülle den Befestigungsring zumindest teilweise ab, wodurch ein großer weicher Anlagebereich für Mund und Kinn des Kindes geschaffen wird.According to a further embodiment, the Saugertülle above the Saugerflansches a constriction. The constriction allows captive pre-assembly of the mounting ring on the teat and thus facilitates handling. In addition, the suction grommet at least partially covers the mounting ring, creating a large soft contact area for the child's mouth and chin.

Gemäß einer weiteren Ausgestaltung ist das Lippenventil in einem oberhalb der Einschnürung angeordneten Bereich der Saugertülle mit größerem Durchmesser angeordnet. In dieser Position stört das Lippenventil nicht die Montage des Trinksaugers mittels des Befestigungsrings an der Trinkflasche. Außerdem ist das Lippenventil von dem Bereich der Anlage von Mund und Kinn des Kindes entfernt, sodass der Druckausgleich nicht behindert wird.In accordance with a further embodiment, the lip valve is arranged in a region of the suction nozzle with a larger diameter arranged above the constriction. In this position, the lip valve does not interfere with the mounting of the teat by means of the mounting ring on the bottle. In addition, the lip valve is away from the area of the mouth and chin of the child so that pressure equalization is not hindered.

Gemäß einer bevorzugten Ausgestaltung ist das Lippenventil im Bereich der Saugertülle mit dem maximalen Durchmesser angeordnet.According to a preferred embodiment, the lip valve is arranged in the region of the suction nozzle with the maximum diameter.

Gemäß einer Ausgestaltung weist der Trinksauger einen aus der Durchtrittsöffnung für flüssige Nahrung bzw. dem Trinkloch hervorstehenden Verschlusszapfen auf. Der Verschlusszapfen ist bevorzugt einteilig mit dem Saugernippel ausgebildet. Bevorzugt besteht der Verschlusszapfen aus demselben Material wie der Saugernippel. Weiterhin bevorzugt ist der Verschlusszapfen integral mit dem gesamten Trinksauger gefertigt. Bevorzugt besteht der Trinksauger einschließlich des Verschlusszapfens aus Silikon oder aus einem thermoplastischen Elastomer oder aus einem spritzgießfähigen Kunststoff. Das Trinkloch ist durch den Verschlusszapfen bis zur Erstbenutzung sicher geschlossen. Der Verschlusszapfen bildet einen Originalitätsverschluss, den der Benutzer unmittelbar vor der Anwendung abtrennen kann, damit das Trinkloch freikommt. Zudem wird die Herstellung durch Spritzgießen vereinfacht, da ein Spritzgießwerkzeug keine Nadel für die Begrenzung eines Trinkloches aufweisen muss, sodass insbesondere der davon verursachte Aufwand für die Werkzeugwartung vermieden wird.According to one embodiment, the teat has a protruding from the passage for liquid food or the drinking hole closure pin. The closure pin is preferably formed integrally with the nipple. Preferably, the closure pin consists of the same material as the nipple. Further preferably, the plug is made integral with the entire teat. The teat, including the closure pin, preferably consists of silicone or of a thermoplastic elastomer or of an injection-moldable plastic. The drinking hole is securely closed by the plug until it is used for the first time. The plug forms a tamper-evident seal that the user can disconnect immediately prior to use to free the drinking hole. In addition, the production is simplified by injection molding, as an injection mold does not need to have a needle for the limitation of a drinking hole, so that in particular the cost of tool maintenance caused by it is avoided.

Gemäß einer Ausgestaltung weist der Verschlusszapfen einen kleinen Handgriff auf. Der Handgriff erleichtert das Lösen des Verschlusszapfens vom Saugernippel, insbesondere durch Abdrehen des Verschlusszapfens vom Saugernippel.According to one embodiment, the closure pin has a small handle. The handle facilitates the release of the closure pin from the nipple, in particular by twisting the plug from the nipple.

Gemäß einer weiteren Ausgestaltung weist der Verschlusszapfen eine Materialschwächung auf. Entlang der Materialschwächung kann der Verschlusszapfen gezielt abgetrennt werden. Weiterhin bevorzugt ist die Materialschwächung im Inneren des Trinkloches angeordnet. Dies ermöglicht es, den Verschlusszapfen unterhalb der Außenoberfläche des Trinksaugers von diesem abzutrennen. Bruchkanten der Trennstelle kommen somit nicht mit dem Säugling in Berührung. Hierfür kann der Verschlusszapfen an den Innenumfang des Trinkloches angebunden sein.According to a further embodiment, the closure pin has a material weakening. Along the material weakening, the locking pin can be selectively separated. Further preferably, the material weakening is arranged in the interior of the drinking hole. This makes it possible to separate the closure pin below the outer surface of the teat from this. Fracture edges of the separation point thus do not come into contact with the infant. For this purpose, the closure pin can be connected to the inner circumference of the drinking hole.

Gemäß einer weiteren Ausgestaltung ist der Trinksauger aus Silikon oder einem thermoplastischen Elastomer oder aus einem anderen spritzgießfähigem Kunststoff hergestellt. Gemäß einer bevorzugten Ausgestaltung ist der Trinksauger spritzgegossen.According to a further embodiment, the teat is made of silicone or a thermoplastic elastomer or of another injection-moldable plastic produced. According to a preferred embodiment of the teat is injection-molded.

Grundsätzlich ist es aber auch möglich, den Trinksauger aus Latex im Tauchverfahren herzustellen. Das Lippenventil kann ggfs. nachträglich geschlitzt werden. Durch die Erfindung ist der Öffnungsdruck des Lippenventils steuerbar.In principle, it is also possible to produce the teat from latex by dipping. The lip valve can optionally be subsequently slotted. By the invention, the opening pressure of the lip valve is controllable.

Ferner betrifft die Erfindung eine Saugflasche mit einem erfindungsgemäßen Trinksauger, der mittels eines Befestigungsringes an einer Trinkflasche montiert ist, wobei der Befestigungsring an einem zylindrischen Mantel Befestigungsmittel aufweist, die mit weiteren Befestigungsmitteln der Trinkflasche zusammenwirken, um den Befestigungsring an der Trinkflasche lösbar zu befestigen, ein Ringflansch des Befestigungsringes einen Raum um die Saugertülle oberhalb des Saugerflansches einnimmt und der Saugerflansch zwischen dem Befestigungsrand der Trinkflasche und dem Ringflansch des Befestigungsringes eingeklemmt ist.Furthermore, the invention relates to a feeding bottle with a teat according to the invention, which is mounted on a drinking bottle by means of a fastening ring, wherein the fastening ring has fastening means on a cylindrical jacket, which cooperate with further fastening means of the drinking bottle to releasably secure the fastening ring to the drinking bottle Ring flange of the mounting ring occupies a space around the Saugertülle above the Saugerflansches and the Saugerflansch is clamped between the mounting edge of the bottle and the annular flange of the mounting ring.

Die Angaben "oben" und "unten" beziehen sich in dieser Anmeldung auf eine Anordnung des Trinksaugers oben auf dem Befestigungsrand einer vertikal ausgerichteten Trinkflasche, wobei der Saugernippel oben und der Boden der Trinkflasche unten angeordnet ist.The terms "top" and "bottom" refer in this application to an arrangement of the teat on top of the mounting edge of a vertically oriented bottle, the nipple top and the bottom of the bottle is arranged below.

In der nachfolgenden Erläuterung verschiedener Ausführungsbeispiele sind übereinstimmende oder im Wesentlichen übereinstimmende Elemente mit denselben Bezugsziffern versehen.In the following explanation of various embodiments, matching or substantially matching elements are given the same reference numerals.

Gemäß Figur 1 hat ein Trinksauger 1 eine balgartige Saugertülle 2, die sich ausgehend von einem größten Durchmesser 3 nach oben verjüngt. Oben trägt die Saugtülle 2 einen Saugernippel 4, der einen Nippelhals 5 und einen Nippelkopf 6 aufweist. Der Nippelkopf 7 ist an einer Seite mit einer schräg zur Mittelachse 8 des Trinksaugers 1.1 geneigten Ablüftung 9 versehen. An der gegenüberliegenden Seite weist er mindestens ein Trinkloch 10 auf.According to FIG. 1 has a teat 1 a bellows-like Saugertülle 2, which tapers from a largest diameter 3 upwards. At the top, the suction nozzle 2 carries a nipple 4, which has a nipple neck 5 and a nipple head 6. The nipple head 7 is on one side with an oblique to the central axis 8 of the Teat vacuum 1.1 inclined vent 9 provided. On the opposite side, it has at least one drinking hole 10.

Unten weist die Saugertülle 2 eine Einschnürung 11 auf. Am unteren Ende der Einschnürung 11 ist die Saugertülle 2 mit einem radial nach außen vorstehenden Saugerflansch 12.1 verbunden, der konzentrisch in die Mittelachse 8 umläuft. Der Saugerflansch 12.1 ist im Wesentlichen eben, hat jedoch in einem Teilbereich seines Umfanges eine nach unten vorstehende Wölbung 13.1. Ferner hat der Saugerflansch 12 am äußeren Rand einen umlaufenden, vertikal hochstehenden Randwulst 14. Am Tiefpunkt seiner Wölbung 13 hat der Saugerflansch 12.1 ein nach unten vorstehendes Lippenventil 15.Below the suction nozzle 2 has a constriction 11. At the lower end of the constriction 11, the Saugertülle 2 is connected to a radially outwardly projecting Saugerflansch 12.1, which concentrically rotates in the central axis 8. The Saugerflansch 12.1 is substantially flat, but has in a portion of its circumference a downwardly protruding buckle 13.1. Furthermore, the Saugerflansch 12 at the outer edge has a circumferential, vertically upstanding edge bead 14. At the bottom of its curvature 13 of Saugerflansch 12.1 has a downwardly projecting lip valve 15th

Gemäß Fig. 1b ist der Saugerflansch 12.1 im Bereich des Lippenventils 15 nach innen verbreitert.According to Fig. 1b the Saugerflansch 12.1 widened in the area of the lip valve 15 inward.

Gemäß Fig. 1c ist das Lippenventil 15.1 im Wesentlichen trichterförmig mit zwei flachen Seitenwänden 16, 17. Die Seitenwände 16,17 bilden mit ihrem unteren Rand Lippen 18, 19 des Lippenventils 15. Der Trinksauger 1.1 ist so gefertigt, dass das Lippenventil im unverformtem Zustand geöffnet ist. Zwischen den Lippen 18, 19 ist eine linsenförmige Ventilöffnung 20 vorhanden. Die Lippen 18, 19 sind radial zum Saugerflansch 12 ausgerichtet. So ist der Trinksauger 1.1 in Fig. 1d gezeigt.According to Fig. 1c the lip valve 15.1 is substantially funnel-shaped with two flat side walls 16, 17. The side walls 16,17 form with their lower edge lips 18, 19 of the lip valve 15. The teat 1.1 is made so that the lip valve is open in the undeformed state. Between the lips 18, 19, a lenticular valve opening 20 is present. The lips 18, 19 are aligned radially to the suction flange 12. So is the teat 1.1 in Fig. 1d shown.

Oberhalb des Lippenventils 15.1 weist die Saugertülle 2 eine radial nach innen gerichtete Einbuchtung 21 auf.Above the lip valve 15.1, the suction nozzle 2 has a radially inwardly directed recess 21.

Wenn die Wölbung 13 des Saugerflansches 12.1 abgeflacht wird, wirkt sich dies auf das Lippenventil 15.1 so aus, dass sich die Lippen 18, 19 aneinander anliegen und die Ventilöffnung 20 schießen. Dies ist in Fig. 1e gezeigt.If the arch 13 of the Saugerflansches 12.1 is flattened, this affects the lip valve 15.1 so that the lips 18, 19 abut each other and shoot the valve opening 20. This is in Fig. 1e shown.

Gemäß Fig. 2 wird der Trinksauger 1.1 an einer Trinkflasche 22 mittels eines Befestigungsrings 23 fixiert. Der Befestigungsring 23 hat am Innenumfang seines annähernd zylindrischen Mantels 24 ein Innengewinde 25 und die Trinkflasche 22 weist am Außenumfang ihres Halses 26 ein Außengewinde 27 auf, sodass der Befestigungsring 23 mit der Trinkflasche 22 verschraubbar ist. Vom oberen Rand des Befestigungsringes 23 steht nach innen ein Ringflansch vor, der im Wesentlichen kreisringscheibenförmig ist.According to Fig. 2 the teat 1.1 is fixed to a bottle 22 by means of a mounting ring 23. The mounting ring 23 has on the inner circumference of its approximately cylindrical shell 24, an internal thread 25 and the bottle 22 has on the outer circumference of its neck 26 an external thread 27, so that the mounting ring 23 is screwed to the bottle 22. From the upper edge of the mounting ring 23 projects inwardly an annular flange, which is substantially annular disc-shaped.

Der Trinksauger 1.1 ist mit der Trinkhülle 2 durch eine zentrale Öffnung 28 des Befestigungsringes 23 hindurchgesteckt, sodass der Ringflansch direkt oberhalb der Oberseite des Saugerflansches 12.1 platziert ist. Beim Festschrauben des Trinksaugers 1.1 mittels des Befestigungsringes 23 wird der Saugerflansch 12.1 mit der Unterseite gegen den Befestigungsrand 29 der Trinkflasche 22 gepresst, der um die Öffnung 30 der Trinkflasche 22 umläuft. Hierbei wird die Wölbung 13 flachgedrückt und das in die Öffnung 28 eingreifende Lippenventil 15.1 schließt sich.The teat 1.1 is inserted with the drinking sheath 2 through a central opening 28 of the fastening ring 23, so that the annular flange is placed directly above the top of the Saugerflansches 12.1. When tightening the teat 1.1 by means of the fastening ring 23, the Saugerflansch 12.1 is pressed with the bottom against the mounting edge 29 of the bottle 22, which rotates about the opening 30 of the bottle 22. Here, the buckle 13 is flattened and engaging in the opening 28 lip valve 15.1 closes.

Wenn am Trinksauger 1.1 gesaugt wird, bildet sich in der Trinkflasche 22 ein Unterdruck aus. Wenn der Unterdruck den Öffnungsdruck des Lippenventils 15 übersteigt, strömt durch einen Spalt zwischen dem Befestigungsring 23 und der Oberseite des Saugerflansches 12.1 Luft nach. Hierdurch wird ein Einfallen des Trinksaugers 1.1 verhindert und vermieden, dass das Kind übermäßige Saugarbeit aufwenden muss.When sucked on the teat 1.1, a negative pressure forms in the bottle 22. When the negative pressure exceeds the opening pressure of the lip valve 15, air flows through a gap between the fastening ring 23 and the top of the suction flange 12.1. As a result, a collapse of the teat 1.1 is prevented and avoided that the child has to spend excessive Saugarbeit.

Der Trinksauger 1.2 von Fig. 3 unterscheidet sich von dem Trinksauger 1.1 dadurch, dass das Lippenventil 15.2 in der Saugertülle 2 oberhalb der Wölbung 13 angeordnet ist. Das Lippenventil 15.2 ist im Bereich des maximalen Durchmessers der Saugertülle 2 angeordnet. Bei dieser Ausführung ist die untere Lippe 18 durch einen Steg 31 stabilisiert, der radial bezüglich des Saugerflansches 12.1 an der Innenseite der Saugertülle 2 angeordnet ist. Der Steg 31 ist mit der Innenseite der unteren Seitenwand 16 und des daran angrenzenden Bereiches der Saugertülle 2 verbunden. Er ist vertikal bezüglich des Saugerflansches 12.1 ausgerichtet. Die Lippen 18, 19 sind horizontal bzw. parallel zum Saugerflansch 12.1 ausgerichtet.The teat 1.2 of Fig. 3 differs from the teat 1.1 in that the lip valve 15.2 is arranged in the Saugertülle 2 above the curvature 13. The lip valve 15.2 is arranged in the region of the maximum diameter of the suction nozzle 2. In this embodiment, the lower lip 18 is through a web 31 stabilized, which is arranged radially with respect to the Saugerflansches 12.1 on the inside of the suction grommet 2. The web 31 is connected to the inside of the lower side wall 16 and the adjacent thereto portion of the suction nozzle 2. It is vertically aligned with respect to the Saugerflansches 12.1. The lips 18, 19 are aligned horizontally or parallel to the suction flange 12.1.

Das Lippenventil 15.2 bildet eine trichterförmige Vertiefung im Bereich des maximalen Außendurchmessers der Saugertülle 2.The lip valve 15.2 forms a funnel-shaped depression in the region of the maximum outside diameter of the suction nozzle 2.

Im unverformten Zustand des Trinksaugers 1.2 sind die Lippen 18, 19 geöffnet. Dies ist in Fig. 3c gezeigt. Wenn der Trinksauger 1.2 wie der Trinksauger 1.1 in Fig. 2 mittels eines Befestigungsringes 23 an einer Trinkflasche 22 fixiert ist, wird die Wölbung 13 flachgepresst. Diese Verformung des Trinksaugers 1.2 wirkt sich auf das Lippenventil 15.2 so aus, dass die Lippen 18, 19 mit einer definierten Flächenpressung zusammengepresst werden. Infolgedessen erfolgt ein Druckausgleich mit der Umgebung, wenn ein bestimmter Unterdruck in der Trinkflasche 12 überschritten wird.In the undeformed state of the teat 1.2, the lips 18, 19 are opened. This is in Fig. 3c shown. When the teat 1.2 as the teat 1.1 in Fig. 2 is fixed by a mounting ring 23 to a bottle 22, the buckle 13 is pressed flat. This deformation of the teat 1.2 affects the lip valve 15.2 so that the lips 18, 19 are pressed together with a defined surface pressure. As a result, a pressure equalization with the environment occurs when a certain negative pressure in the bottle 12 is exceeded.

Der Trinksauger 1.3 von Fig. 4 unterscheidet sich von dem Trinksauger 1.2 insbesondere dadurch, dass der Saugerflansch 12.2 im unverformten Zustand keine Wölbung aufweist. Am unteren Rand der trichterförmigen Öffnung des Lippenventils 15.2 steht ein Wulst 32 vor. Im Beispiel ist der Wulst 32 sichelförmig ausgebildet. Außerdem ist der Saugernippel 4.2 zapfenförmig mit kuppelförmigem Ende.The teat 1.3 of Fig. 4 differs from the teat 1.2 especially in that the Saugerflansch 12.2 has no buckling in the undeformed state. At the bottom of the funnel-shaped opening of the lip valve 15.2 is a bead 32 before. In the example, the bead 32 is sickle-shaped. In addition, the nipple nipple 4.2 peg-shaped with dome-shaped end.

Bei dem Trinksauger 1.3 ist im unverformten Zustand das Lippenventil 15.2 geöffnet. Wenn der Trinksauger 1.3 mittels eines Befestigungsringes 23 an einer Trinkflasche 22 montiert ist, drückt der Ringflansch des Befestigungsringes 23 gegen den Wulst 32. Hierdurch wird das Lippenventil 15.2 dergestalt verformt, dass die Lippen 18, 19 mit einer definierten Flächenpressung aneinander anlegen und die Öffnung 20 geschlossen wird.In the teat 1.3, the lip valve 15.2 is open in the undeformed state. When the teat is 1.3 mounted by means of a mounting ring 23 to a bottle 22, the annular flange of the mounting ring 23 presses against the bead 32. As a result, the lip valve 15.2 is deformed such that the lips 18, 19 create a defined surface pressure against each other and the opening 20 is closed.

Wenn ein bestimmtes Vakuum in der Trinkflasche 1.3 überschritten wird, öffnet das Lippenventil 15.2 und ein Druckausgleich wird erreicht.When a certain vacuum in the bottle 1.3 is exceeded, the lip valve 15.2 opens and pressure equalization is achieved.

Der Trinksauger 1.4 von Fig. 5 unterscheidet sich von dem Trinksauger von Fig. 1 zunächst dadurch, dass das Lippenventil 15 um 90° auf dem Saugerflansch 12.1 versetzt ist.The teat 1.4 of Fig. 5 is different from the teat of Fig. 1 initially by the fact that the lip valve 15 is offset by 90 ° on the Saugerflansch 12.1.

Ferner ist das Trinkloch 10 durch einen einteilig und aus demselben Material wie der Saugernippel 5 gebildeten Verschlusszapfen 33 verschlossen. Der Verschlusszapfen 33 ist integral mit dem gesamten Trinksauger 1.4 ausgebildet. Der Verschlusszapfen 33 ist am Rand des Trinkloches 10 mit der Wand des Saugernippels verbunden. Er weist einen Handgriff 34 auf. Der Handgriff 34 erleichtert das Abdrehen des Verschlusszapfens 33 zum Öffnen des Trinkloches 10.Furthermore, the drinking hole 10 is closed by a one-piece and from the same material as the nipple 5 formed closure pin 33. The plug 33 is integrally formed with the entire teat 1.4. The closure pin 33 is connected at the edge of the drinking hole 10 with the wall of the nipple nipple. He has a handle 34. The handle 34 facilitates the twisting of the locking pin 33 for opening the drinking hole 10th
