Definitions
- the invention relates to a ventilation device for a drinking bottle according to the preamble of claim 1, see for example US 2004/089 626 A1 ,
- a disadvantage of the known device is that the air-guiding pressure equalization path is formed as an angled tube with a constant narrow cross section, which tends very easily to the closure when the drinking liquids tend in the bottle for bonding. In such a case, the intended ventilation function of the bottle is impaired or disabled.
- valve slot of the valve body tends to stick and thus adversely affect the ventilation function of the bottle. This also applies to many other protective applications which are not mentioned, in which the operating principle of the valve slot is used as membrane function.
- the non-simple hygienic cleaning is considered in the above-mentioned device, and the risk that assumes that the relatively small valve hollow body, as an additional part, can be swallowed in small form by infants.
- US 2006/0213859 A1 is also a device for pressure equalization of a bottle during sucking known.
- a disadvantage of this device mentioned above is also the difficult hygienic cleaning of many items and the high production cost of the device.
- the invention has the object of developing the generic device such that the mentioned disadvantages are resolved and a slight suction from the bottle while avoiding leaks during suction are possible. In addition, a simple and safe hygienic cleaning of their items should be achieved.
- a device for pressure equalization in a bottle is specified, which allows a smooth suction while avoiding leaks.
- the device is further characterized by a very small number of simply designed components, resulting in further cost savings and a simple and reliable operation.
- the device according to the invention allows hygienic maintenance and protects infants from improper use of the items. Due to the special design of the parts, a cost-saving design and a simple and safe operation of the device is achieved.
- the embodiment according to claim 6 and 8 allows hygienic maintenance and protects infants from injury and improper use of the items.
- a drinking bottle 1 according to Fig. 1 consisting of a container 2 with external thread 28 for receiving a drinking liquid 3, is screwed together with a sucker 4 and a ventilation device 5 via a threaded ring 8 with internal thread 29 to form a functional unit.
- an air-permeable free gap 30 which is required as a thread flank clearance to the screw ring 8 easily, without jamming, with the container 2 to screw.
- the ventilation device 5 see Fig. 1 , is made of two parts, a ventilation disc 6, Fig. 2 and Fig. 3 and a ventilation pipe 7 assembled into one unit. For cleaning purposes, this unit is easily dismantled into its components.
- the ventilation disc 6 lies with a first end face on the edge of the opening of the container 2 sealingly. Its first end face opposite the second end face 12 is sealingly engaged with a terminal surface 18 formed by a flange (20) of the nipple 4.
- a ventilation tube 7 is inserted under slight tension, so that it is frictionally defined therein.
- venting of the container 2 extends via the ventilation tube 7, the connecting bore 14, the ventilation channel 13 and the free gap 30 at the threaded connection 9 to the outside 27th
- the ventilation disc 6 see Fig. 1 . Fig. 2 and Fig. 3 , an opening 15, which allows an unhindered passage of the drinking liquid 3 from the container 2 into the inner vacuum chamber 16.
- FIG. 1 and Fig. 2 is formed as a triangular surface 19.
- this pointed configuration of the triangular surface 19 is achieved that when screwing the container 2 with the screw ring 8 of the closed sealing web 17 of the ventilation disc 6 penetrates without great effort in the Saugerflansch 20 and with a high degree of leakage of the drinking liquid 3 from the container 2 on the Ventilation duct 13 and the gap 30 of the threaded connection 9 prevented to the outside. This ensures suction without leaks.
- the upper end surface 21 of the ventilation pipe 7, see Fig. 1 Runs to the tube surface at an oblique angle, whereby an easier installation of the ventilation tube 7 in the bore 10a of the ventilation disc 6 and a secure equalizing air supply of the container 2 is achieved. So that no confusion occurs during assembly, the lower end surface 22 of the ventilation tube 7 is also designed with an oblique surface course.
- the working method is as follows:
- Fig. 1 shows the bottle 1 at rest. In this position, the liquid level in the container 2 and the ventilation pipe 7 is the same height. As soon as the drinking bottle is brought from the rest position into an oblique drinking position with the teat 4 directed downwards, liquid from the suction hole 23 drips outward drop by drop 27. An additional suction further supports this liquid outlet. In this position, the free space 11 moves above the drinking liquid 3 in the space region 26 to the container bottom 25, in which after leaving the first liquid drops from the suction hole 23, a negative pressure is created.
- connection hole 14a If the air cushion degraded so far that the liquid 24 reaches the connection hole 14a, 14 in the ventilation tube 7 in the drinking position with a closed suction hole 23, so can not through the tight connection bore 14 on the congestion effect of the viscous liquid 24 in the conical portion 14a Ventilation duct 13 and the free gap 30 to the outside 27 occur.
- Another variant of use with negative pressure compensation is a drinking bottle 1, in which only the ventilation disc 6, without the vent tube 7, is used.
- the air balancing bubbles pass through the drinking liquid 3.
- FIG. 6 A further embodiment without ventilation pipe 7 is in Fig. 6 shown, which is characterized by a cost-effective production and easy handling.
- FIG. 7 illustrated second embodiment of the first portion of the pressure equalization path forming ventilation duct 13 is the same as in the in the FIGS. 1 to 6 illustrated embodiments in the ventilation disc 6a formed such that it has the shape of a second end face 35 toward open channel, which is closed by the second end face 35 tightly adjacent end face of the Saugerflansches 20a.
- a projecting annular bead 33 is formed, whose cross-section increases toward the free edge of the annular bead 33 out.
- This annular bead 33 is latched due to the elastic deformability of the nipple 4a in a complementary to the annular bead 33 annular groove 34 of the ventilation disc 6a.
- the sucker 4b and the ventilation disc are formed as an integral part of the Saugerflansches 20b.
- the actual vacuum cleaner 4a can be molded directly onto the ventilation disc.
- the latter can for example consist of a hard plastic, whereas the sucker 4a made of a softer material, such as silicone.
- the ventilation disc and the nipple could be glued together. In all these cases they then form the in Fig. 8 represented unified Saugerflansch 20b, in the interior of which the first portion 13a and the adjoining second portion 14, 14a of the pressure equalization path are formed.

In einem solchen Fall ist die vorgesehene Belüftungsfunktion der Trinkflasche beeinträchtigt oder außer Kraft gesetzt.A disadvantage of the known device is that the air-guiding pressure equalization path is formed as an angled tube with a constant narrow cross section, which tends very easily to the closure when the drinking liquids tend in the bottle for bonding. In such a case, the intended ventilation function of the bottle is impaired or disabled.
Als weiterer Nachteil dieser Ausführung wird die schwierige Reinigung und hygienische Wartung des abgewinkelten Röhrchens in der Lüftungsscheibe und deren kostenaufwendige Fertigung angesehen.Another disadvantage of this design, the difficult cleaning and hygienic maintenance of the angled tube in the ventilation disc and their costly production is considered.
Aus
Nachteilig bei dieser Vorrichtung ist, dass der Ventilschlitz des Ventilhohlkörpers zum Verkleben neigt und so die Belüftungsfunktion der Trinkflasche beeinträchtigt. Dies trifft auch für viele andere nicht genannte Schutzanmeldungen zu, bei denen das Wirkprinzip des Ventilschlitzes als Membranfunktion zur Anwendung kommt.A disadvantage of this device is that the valve slot of the valve body tends to stick and thus adversely affect the ventilation function of the bottle. This also applies to many other protective applications which are not mentioned, in which the operating principle of the valve slot is used as membrane function.
Als weiterer Nachteil wird bei der oben genannten Vorrichtung die nicht einfache hygienische Reinigung angesehen, und die Gefahr, die davon ausgeht, dass der relativ kleine Ventilhohlkörper, als zusätzliches Teil, in loser Form von Kleinkindern verschluckt werden kann.As a further disadvantage, the non-simple hygienic cleaning is considered in the above-mentioned device, and the risk that assumes that the relatively small valve hollow body, as an additional part, can be swallowed in small form by infants.
Aus

Die Entlüftung des Behälters 2 verläuft über das Lüftungsrohr 7, die Verbindungsbohrung 14, den Lüftungskanal 13 und den freien Spalt 30 an der Gewindeverbindung 9 nach Außen 27.The venting of the
Der eng ausgeführte Entlüftungsquerschnitt des Lüftungskanals 13 mit der Verbindungsbohrung 14 steigt durch die konische Fortsetzung 14a bis zum Lüftungsrohr 7 stetig an. Dadurch kann die Ausgleichsluft von Außen 27 über den Spalt 30 der Gewindeverbindung 9, den Lüftungskanal 13, die Verbindungsbohrung 14 mit der konischen Fortsetzung 14a und das Lüftungsrohr 7, mit stetig steigenden freien Querschnitten ungehindert und ohne Druckstau in den Behälter 2 einströmen und den darin entstandenen Unterdruck ausgleichen, was zu einem leichten Saugen führt.The closely executed ventilation cross-section of the
Dagegen kann die gegenüber der Ausgleichsluft zähere Trinkflüssigkeit 3 über das Lüftungsrohr 7, wegen der starken Drosselung an der als Staudüse ausgeführten Verbindungsbohrung 14 über den Lüftungskanal 13 und den freien Spalt 30 der Gewindeverbindung 9 nicht nach Außen 27 gelangen, so dass Leckverluste von Trinkflüssigkeit 3 über diesen Weg vermieden werden.In contrast, the toughened compared to the compensating
Im weiteren Verlauf weist die Lüftungsscheibe 6, siehe
Mit dieser Ausgestaltung sind alle Flächen der Lüftungsscheibe für eine sehr leichte und sichere hygienische Reinigung zugänglich.With this configuration, all surfaces of the ventilation disc for a very easy and safe sanitary cleaning accessible.
Eine weiteres vorteilhaftes Ausgestaltungsmerkmal der Lüftungsscheibe 6 ist der umlaufende geschlossene Dichtungssteg 17, der von der zweiten Stirnseite 12 hin zur unteren Saugerflanschfläche 18 spitz zuläuft und in der Schnittdarstellung,
Die obere Endfläche 21 des Lüftungsrohrs 7, siehe
Sobald das Lüftungsrohr 7 frei von Trinkflüssigkeit 3 ist, wird der Unterdruck im Raumbereich 2.6 unter dem Behälterboden 25 ausgeglichen. Der Tropfenstrom aus dem Saugloch 23 reißt dadurch nicht ab, da jeder momentane Unterdruck, hervorgerufen durch das austretende Tropfenvolumen, sofort durch die nachströmende Ausgleichsluft kompensiert wird. Mit geringer Saugunterstützung wird ein sehr leichtgängiges Saugen erreicht. Da das Lüftungsrohr 7 sich bis in die Nähe des Behälterbodens 25 erstreckt, wird mit der Belüftungsvorrichtung 5 erreicht, dass während des Saugens Luftausgleichsblasen durch die Trinkflüssigkeit 3 hindurchwandern.As soon as the
Wird die Trinkflasche aus der Trinklage wieder in die Ruhelage zurück gebracht, dann dringt langsam die Trinkflüssigkeit 3 wieder in das Lüftungsrohr 7 ein und verdrängt das darin eingeschlossene Luftpolster über die Verbindungsbohrung 14, den Lüftungskanal 13 und den Spalt 30 der Gewindeverbindung 9 nach Außen 27.If the bottle is brought back from the drinking position to the rest position, then the liquid 3 slowly penetrates into the
Dieser Luftpolsterabbau erfolgt, wegen der Umkehrrichtung der Luftströmung mit den sich verjüngenden Entlüftungsquerschnitten und der damit einhergehenden starken Drosselung des verdrängten Luftpolsters, relativ langsam, so dass das noch nicht abgebaute Luftpolster das Lüftungsrohr 7 blockiert und die Trinkflüssigkeit 24 im Lüftungsrohr 7 über diesen Weg, selbst wenn die Trinkflasche 1 geschüttelt wird, nicht nach Außen 27 dringen kann.This air cushion degradation takes place, because of the reverse direction of the air flow with the tapered vent cross sections and the associated strong throttling of the displaced air cushion, relatively slowly, so that the not yet degraded air cushion blocks the
Ist das Luftpolster so weit abgebaut, dass die Trinkflüssigkeit 24 im Lüftungsrohr 7 in der Trinklage bei verschlossenem Saugloch 23 die Verbindungsbohrung 14a, 14 erreicht, so kann wegen der Stauwirkung der zäheren Trinkflüssigkeit 24 im konischen Teil 14a diese nicht durch die enge Verbindungsbohrung 14 über den Lüftungskanal 13 und den freien Spalt 30 nach Außen 27 treten.If the air cushion degraded so far that the liquid 24 reaches the
Eine weitere Gebrauchsvariante mit Unterdruckausgleich stellt eine Trinkflasche 1 dar, bei der nur die Lüftungsscheibe 6, ohne das Lüftungsrohr 7, zum Einsatz kommt.
