Description

Die Erfindung bezieht sich auf eine auslaufgeschützte Flasche für Kindernahrung.The invention relates to a leak-proof bottle for baby food.

Bei bekannten Flaschen für Kindernahrung hat der Sauger am unteren Rand einen umlaufenden Saugerflansch, der mittels eines auf zein Außengewinde der Flasche aufgeschraubten Schraubringes abdichtend am Rand einer Flaschenöffnung festgelegt ist. Um das Auslaufen der Flüssigkeit in Trinkpausen zu verhindern, wird zwischen Saugerflansch und Flaschenrand ein Deckel gelegt und mittels des Schraubringes festgeklemmt.In known bottles for infant food, the teat at the bottom of a peripheral Saugerflansch which is set by means of a screwed on zein external thread of the bottle screw ring sealingly on the edge of a bottle opening. In order to prevent the leakage of the liquid in drinking breaks, a lid is placed between the suction flange and the edge of the bottle and clamped by means of the screw ring.

Aus der DE 101 57 071 C1 ist eine anwenderfreundlichere auslaufgeschützte Flasche für Kindernahrung bekannt. Diese hat einen auf das Außengewinde der Flasche aufgeschraubten unteren Verschlußring, der eine erste Sitzfläche mit mindestens einem ersten Durchflußloch aufweist. Ein oberer Verschlußring hat eine zweite Sitzfläche mit mindestens einem zweiten Durchflußloch. Die beiden Verschlußringe sind über Verriegelungselemente relativ zueinander drehbar und lösbar miteinander verriegelt. Durch Drehen des oberen Verschlußringes sind die ersten und zweiten Durchflußlöcher in einander überdeckende und nicht überdeckende Stellungen bringbar. Ein Trinksauger ist mittels eines Schraubringes mit einem Außengewinde des oberen Verschlußringes verschraubt. Wenn die Durchflußlöcher einander überdecken, ist durch den Trinksauger Kindernahrung entnehmbar. Überdecken die Durchflußlöcher einander nicht, so ist die Entnahme von Kindernahrung durch den Trinksauger gesperrt.From the DE 101 57 071 C1 is a more user-friendly leak-proof bottle for baby food. This has a screwed onto the external thread of the bottle lower closure ring having a first seat with at least a first flow hole. An upper lock ring has a second seat with at least one second flow hole. The two locking rings are rotatable relative to each other via locking elements and releasably locked together. By turning the upper locking ring, the first and second flow holes can be brought into overlapping and non-overlapping positions. A teat is screwed by means of a threaded ring with an external thread of the upper locking ring. If the flow holes cover each other, infant formula can be removed through the teat. Cover the flow holes not each other, so the removal of infant food is blocked by the teat.

Bei dem Ausführungsbeispiel weisen die Verschlußringe konische Sitzflächen auf. Ferner sind Dichtringe an der Unterseite des unteren Verschlußringes und an der Oberseite der ersten Sitzfläche vorhanden. Der untere Verschlußring weist einen vom unteren Rand der konischen Sitzfläche nach innen vorstehenden Verriegelungsvorsprung auf und der obere Verschlußring hat vom unteren Rand der zweiten konischen Sitzfläche vorstehende Schnappzungen, welche den Verriegelungsvorsprung hintergreifen.In the embodiment, the closure rings on conical seating surfaces.

Das Dichtmaterial ist folglich in einem Arbeitsgang mit einem weniger aufwendigen Spritzgußwerkzeug herstellbar, als die separaten Dichtringe der eingangs erwähnten Auslaufsicherung. Ferner wird durch das den Rand des Durchflußloches vollständig umgebende Dichtmaterial vermieden, daß sich Verunreinigungen im Dichtungsbereich ansammeln. Auch diese Flasche ist insgesamt herstellungs- und anwendungsfreundlicher.In this bottle, the sealing material extends from the seat through the through holes over the bottle interior facing side to the sealing surface of the first middle part. The sealing material is therefore produced in one operation with a less expensive injection molding tool, as the separate sealing rings of the aforementioned leakage protection. Furthermore, it is avoided by the edge of the Durchflußloches completely surrounding sealing material that accumulate impurities in the sealing area. Also, this bottle is overall manufacturing and application friendly.

Dadurch, daß bei dieser Flasche ein Bajonettverschluß zwischen unterem Verschlußring und oberem Verschlußring vorhanden ist, ist es möglich, die Verriegelung außerhalb des Bereiches der Verschlußringe anzubringen, der in Kontakt mit Kindernahrung kommt. Hierdurch wird einer Ansammlung von Verunreinigungen entgegengewirkt und der Aufwand für die Reinigung des Auslaufschutzes verringert. Außerdem wird durch die Trennung von Ventilbereich und Verriegelungsbereich des Auslaufschutzes dem Anwender das Verständnis und damit die Bedienung der Flasche erleichtert. Ferner ist es für das Öffnen des Bajonettverschlusses nicht erforderlich, daß der Anwender von Nahrungsmittel verschmutzte Teile anfaßt. Schließlich ist der Bajonettverschluß mit geringerem Aufwand produzierbar, als die bekannte Verriegelung mit an den Sitzflächen angeformten Schnappelementen. Auch diese Lösung ist für Herstellung und Anwendung vorteilhaft.By providing a bayonet closure between the lower closure ring and the upper closure ring in this bottle, it is possible to mount the latch outside the region of the closure rings which come into contact with infant food. As a result, an accumulation of impurities is counteracted and reduces the cost of cleaning the leakage protection. In addition, the separation of the valve area and the locking area of the leakage protection makes it easier for the user to understand and thus operate the bottle. Furthermore, it is not necessary for the opening of the bayonet closure that the user of contaminated food parts handles. Finally, the bayonet lock can be produced with less effort than the known locking with molded on the seats snap elements. This solution is also advantageous for production and application.
