Abstract

The closure according to the invention for a drinking bottle (1) exhibits a mouthpiece (7), of which a threaded part (11) is arranged so that it can be axially moved and is closed when pushed in by means of a bung (19) fixed to the threaded part (11). A ventilation channel (21) located at the side outside the mouthpiece (7) allows air to penetrate inside the bottle and prevents low pressure arising inside the bottle. <IMAGE>

Description

Gegenstand der vorliegenden Erfindung ist ein Verschluss für eine Trinkflasche mit einer auf dem Flaschenhals feststellbaren Verschlusskappe gemäss Oberbegriff des Patentanspruches 1.
Solche Flaschen werden insbesondere von Radfahrern benützt. Damit eine Verschmutzung des Inhaltes und das Ausschütten während des Fahrens verhindert werden kann, werden solche Flaschen mit verschliessbaren Deckeln oder Kappen versehen.The present invention relates to a closure for a drinking bottle with a closure cap that can be ascertained on the bottle neck according to the preamble of patent claim 1.
Such bottles are used especially by cyclists. In order to prevent contamination of the contents and spilling out while driving, such bottles are provided with closable lids or caps.

Aus der deutschen Offenlegungsschrift 35 14 261 ist eine Flasche für Radfahrer bekannt, bei der das Mundstück axial aus der Verschlusskappe herausziehbar und dadurch eine Durchtrittsöffnung für die in der Flasche befindliche Flüssigkeit gebildet wird. Je nach Stellung des Mundstückes kann der Radfahrer entweder die Flüssigkeit in feinen Strahlen, z.B. zum Benetzen seines Gesichtes, austreten lassen oder er kann die Trinköffnung soweit freilegen, dass durch Zusammendrücken der meist aus einem weichen Kunststoff hergestellten Flasche das Trinken zu ermöglichen. Durch Zurückstossen des Mundstückes wird die Flasche anschliessend wieder dicht verschlossen.A bottle for cyclists is known from German Offenlegungsschrift 35 14 261, in which the mouthpiece can be pulled axially out of the closure cap, thereby forming a passage opening for the liquid in the bottle. Depending on the position of the mouthpiece, the cyclist can either spray the liquid in fine jets, e.g. to wet his face, let it come out or he can expose the drinking opening to the extent that it is possible to drink by squeezing the bottle, which is usually made of a soft plastic. The bottle is then sealed again by pushing back the mouthpiece.

Aus der US-Patentschrift 3,295,294 ist weiter ein Flaschenverschluss für Spenderflaschen bekannt, welcher einen in einem Schraubteil axial verschiebbaren Ausgussteil aufweist, dessen Bohrung bei eingeschobenem Ausgussteil durch einen im Innern der Verschlusskappe koaxial zur Ausgussbohrung angeordneten Zapfen sicher verschlossen wird.From US Pat. No. 3,295,294, a bottle stopper for dispenser bottles is also known, which has a pouring part that is axially displaceable in a screw part, the bore of which is securely closed when the pouring part is pushed in by a pin arranged coaxially with the pouring hole in the inside of the closure cap.

Beide bekannten Verschlüsse eignen sich für Flaschen, die bei der Flüssigkeitsabgabe zusammengedrückt werden und bei denen die Belüftung des Innenraumes nach der Entnahme erfolgen kann. Eine kontinuierliche Entnahme von Flüssigkeit oder die Verwendung einer festen, z.B. aus Metall gefertigten Flasche ist nicht möglich.Both known closures are suitable for bottles that are compressed when dispensing liquid and in which the ventilation of the Interior can take place after removal. It is not possible to draw liquid continuously or to use a solid bottle made of metal, for example.

Aus der US-Patentschrift 4,852,781 ist weiter eine Trinkflasche für Laufsportler bekannt, welche auf dem Rücken getragen und welcher durch einen Schlauch Flüssigkeit entnommen wird. Eine in der Verschlusskappe angebrachte, seitlich mündende Entlüftungsbohrung erlaubt eine kontinuierliche Entnahme von Flüssigkeit. Diese bekannte Flasche hat den Nachteil, dass weder die Hauptentnahmeöffnung noch die Entlüftungsöffnung verschliessbar sind, und der Entnahmeschlauch durch den Verschluss hindurch bis zum Boden der Flasche geführt ist, so dass eine Verwendung durch Radfahrer, die die Flasche mit Verschluss nach unten am Mund ansetzen, nicht eignet.From US Pat. No. 4,852,781, a drinking bottle for runners is also known, which is carried on the back and which liquid is removed through a tube. A vent hole at the side, which opens into the cap, allows liquid to be withdrawn continuously. This known bottle has the disadvantage that neither the main removal opening nor the ventilation opening can be closed, and the removal hose is guided through the closure to the bottom of the bottle, so that it can be used by cyclists who place the bottle with the closure down on their mouth, not suitable.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, einen Verschluss für eine Trinkflasche zu schaffen, welcher eine kontinuierliche Entnahme von Flüssigkeit erlaubt, zwischen den Flüssigkeitsentnahmen eine Bereitschaftsstellung aufweist und nach Gebrauch einen dichten Verschluss ermöglicht.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of creating a closure for a drinking bottle, which allows a continuous withdrawal of liquid, has a standby position between the liquid withdrawals and enables a tight closure after use.

Der erfindungsgemässe Verschluss erlaubt ein verschüttungsfreies Trinken, weil der Trinkende das Mundstück erst nach dem Ansetzen der Flasche am Mund mit den Zähnen vollständig herauszieht und damit die Flüssigkeitsabgabe freigibt. Durch die teilweise geöffnete Entlüftungsbohrung in der Zwischenstellung kann ein dauernder Druckausgleich erfolgen, so dass beim Herausziehen des Zapfens keine Flüssigkeit unter Druck austritt. Nach Beendigung des Trinkvorganges schiebt der Trinkende mit der Zunge, den Lippen oder den Zähnen das Mundstück wieder zurück in den Verschluss, so dass beim Zurückführen der Flasche vom Mund zum Aufbewahrungsort am Vorderrohr des Fahrrades keine Flüssigkeit ausfliessen kann und die Flasche dennoch jederzeit trinkbereit bleibt. Mit dem am Mundstück befestigten oder angespritzten Flansch kann gleichzeitig mit dem Einschieben des Mundstückes die Entlüftungsöffnung ganz oder teilweise verschlossen werden. Durch die statische Höhendifferenz zwischen den Entlüftungslöchern und die Ausflussöffnung kann während des Trinkens und bei Trinkunterbrüchen zum Atmen keine Flüssigkeit durch die Entlüftungsbohrung und damit neben dem Mundstück austreten. Bei längeren Trinkunterbrüchen mit gestürzter Flasche können allenfalls einige Tropfen austreten.The closure according to the invention permits spill-free drinking because the drinker only completely pulls out the mouthpiece with his teeth after the bottle has been placed on the mouth and thus releases the liquid. Due to the partially opened vent hole in the intermediate position, a constant pressure equalization can take place, so that no liquid escapes under pressure when the pin is pulled out. At the end of the drinking process, the drinker pushes the mouthpiece back into the cap with his tongue, lips or teeth, so that when the bottle is returned from the mouth to the storage location on the front tube of the bicycle, no liquid can flow out and the bottle remains ready to drink at any time. With the flange attached or molded onto the mouthpiece, the vent opening can be completely or partially closed at the same time as the mouthpiece is inserted. Due to the static height difference between the ventilation holes and the outflow opening, no liquid can flow through the ventilation hole during drinking and during breaks in breathing and thus exit next to the mouthpiece. In the event of longer interruptions in drinking with a bottle that has fallen, a few drops may escape.

Anhand eines illustrierten Ausführungsbeispieles wird die Erfindung näher erläutert.
Es zeigen:

  • Figur 1 eine Ansicht einer Trinkflasche mit einer aufgesetzten Verschlusskappe,
  • Figur 2 die Verschlusskappe mit eingeschobenem Mundstück und
  • Figur 3 die Verschlusskappe mit vollständig herausgezogenem Mundstück (Trinkstellung) und
  • Figur 4 eine Ansicht des Dorns von unten.
The invention is explained in more detail with the aid of an illustrated embodiment.
Show it:
  • FIG. 1 shows a view of a drinking bottle with an attached cap,
  • Figure 2 shows the cap with the mouthpiece inserted and
  • Figure 3 shows the cap with the mouthpiece completely pulled out (drinking position) and
  • Figure 4 is a view of the mandrel from below.

In Figur 1 ist schematisch eine Trinkflasche 1 mit einer auf dem Flaschenhals 3 aufgeschraubten Verschlusskappe 5 dargestellt. Auf der Verschlusskappe 5 ist ein axial in dieser verschiebbar geführtes Mundstück 7 sichtbar. Die Flasche 1 ist derart ausgebildet, dass sie in eine an Fahrrädern von Rennfahrern vorhandene Halterung am Vorderrohr einlegbar ist.FIG. 1 shows schematically a drinking bottle 1 with a cap 5 screwed onto the bottle neck 3. An axially displaceably guided mouthpiece 7 is visible on the closure cap 5. The bottle 1 is designed in such a way that it can be inserted into a holder on the front tube which is present on bicycles of racing drivers.

Die Verschlusskappe 5 besteht aus einem aus Kunststoff oder aus Metall hergestellten, den Flaschenhals 3 sowohl innen als auch aussen umfassenden, einen Gewindeabschitt 9 aufweisenden Schraubteil 11 mit einer zentralen Bohrung 13, in welche das Mundstück 7 einschiebbar ist. Die Bohrung 13 weist im oberen Teil einen zylindrischen Abschnitt 15 auf. Im unteren Abschnitt der Bohrung 13 sind eine seitliche Erweiterung 17 oder Stege in den Schraubteil 11 eingelassen, welche zur Unterseite 18 der Verschlusskappe 5 hin offen sind. Am unteren Ende der Verschlusskappe 5 ist ein Steg 14 angeordnet. Auf dem Steg 14 sitzt zentrisch zur Bohrung 13 ein vorzugsweise leicht konisch geformter Zapfen 19, dessen Durchmesser d gleich oder etwas kleiner ist als der Durchmesser D der Bohrung 13.The closure cap 5 consists of a screw part 11 made of plastic or metal and having the bottle neck 3 both inside and outside and having a threaded section 9 and having a central bore 13 into which the mouthpiece 7 can be inserted. The bore 13 has a cylindrical section 15 in the upper part. In the lower section of the bore 13, a lateral extension 17 or webs are let into the screw part 11, which are open towards the underside 18 of the closure cap 5. At the lower end of the cap 5, a web 14 is arranged. A preferably conical pin 19, whose diameter d is equal to or slightly smaller than the diameter D of the bore 13, sits on the web 14 centrally to the bore 13.

Versetzt zur Achse A und ausserhalb der Bohrung 13 und der Erweiterung 17 der Verschlusskappe 5 ist ein zylindrischer oder konischer Belüftungskanal 21 angebracht, welcher am flaschenseitigen Ende einen geringeren Durchmesser (Bohrung 22 bei zylindrischer Gestalt) aufweist als auf der Seite des Mundstückes 7.Offset from the axis A and outside the bore 13 and the extension 17 of the closure cap 5 is a cylindrical or conical ventilation channel 21 which has a smaller one at the bottle-side end Diameter (bore 22 with a cylindrical shape) has than on the side of the mouthpiece 7.

Auf der Oberseite des Schraubteiles 11 ist eine kreisförmige, zur Achse A konzentrisch liegende Ausnehmung 23 vorgesehen, in welche ein am Mundstück 7 angebrachter Flansch 25 eingreifen und in formschlüssige Anlage gelangen kann. Oberhalb des Flansches 25 ist am Mundstück 7 vorzugsweise ein umlaufender, abgerundete Kanten aufweisender Absatz 27 vorgesehen. Das Mundstück 7 weist eine zentrale durchgehende Saugbohrung 29 auf, deren Durchmesser am flaschenseitigen Ende des Mundstückes 7 geringfügig kleiner sein kann.On the upper side of the screw part 11 there is a circular recess 23 which is concentric to the axis A and into which a flange 25 attached to the mouthpiece 7 can engage and engage in a form-fitting manner. Above the flange 25, a circumferential, rounded-off shoulder 27 is preferably provided on the mouthpiece 7. The mouthpiece 7 has a central, continuous suction bore 29, the diameter of which can be slightly smaller at the bottle-side end of the mouthpiece 7.

Unterhalb des Flansches 25 weist das Mundstück 7 einen im wesentlichen zylindrisch ausgebildeten Abschnitt 31 auf, welcher in der Bohrung 13 des Schraubteiles längsgeführt ist. Auf dem Mantel des zylindrischen Abschnittes 31 können radial umlaufende Rippen 33 angebracht sein, welche in entsprechend angeordnete umlaufende Nuten 34 in der Bohrung 13 eingreifen und das Mundstück 7 in der eingeschobenen, einer mittleren und in der ausgezogenen Stellung festhalten.Below the flange 25, the mouthpiece 7 has a substantially cylindrical section 31 which is guided longitudinally in the bore 13 of the screw part. Radially circumferential ribs 33 can be attached to the jacket of the cylindrical section 31, which engage in correspondingly arranged circumferential grooves 34 in the bore 13 and hold the mouthpiece 7 in the inserted, a middle and in the extended position.

Das vollständig eingeschobene Mundstück 7 liegt, wie Figur 2 zeigt, mit der Unterseite des Flansches 25 auf dem Boden 26 der Ausnehmung 23 an, und das untere Ende des zylindrischen Abschnittes 31 ist über den Zapfen 19 geführt. Die Saugbohrung 29 ist in dieser Stellung durch den Zapfen 19 dicht verschlossen und ein Austritt von Flüssigkeit aus der Flasche 1 wird in jeder Lage verhindert.The fully inserted mouthpiece 7, as shown in FIG. 2, rests with the underside of the flange 25 on the bottom 26 of the recess 23, and the lower end of the cylindrical section 31 is guided over the pin 19. The suction bore 29 is sealed in this position by the pin 19 and leakage of liquid from the bottle 1 is prevented in any position.

Der Belüftungskanal 21 wird bei eingeschobenem Mundstück 7 durch einen vorzugsweise konischen Dorn 30 vollständig verschlossen. Bei teilweise ausgefahrenem Mundstück 7 (in der Zwischenstellung) kann durch seitlich am Dom 30 angebrachte gerade oder schraubenlinienförmig verlaufende Nuten 32 gerade so viel Luft durchtreten, dass ein Druckausgleich zwischen dem Flascheninnern und der Atmosphäre erfolgt und dennoch bei umgefallener oder gestürzter Flasche 1 die Flüssigkeit höchstens tropfenweise austreten kann.The ventilation channel 21 is completely closed by a preferably conical mandrel 30 when the mouthpiece 7 is inserted. When the mouthpiece 7 is partially extended (in the intermediate position), just as much air can pass through the straight or helical grooves 32 on the side of the dome 30 that there is pressure equalization between the inside of the bottle and the atmosphere, and the liquid at most if the bottle 1 has fallen or fallen over can drop out.

Beabsichtigt der Radfahrer, aus der Flasche 1 zu trinken, so zieht er entweder von Hand oder nach dem Ansetzen des Mundstückes 7 am Mund mit seinen Zähnen das Mundstück 7 axial aus dem Schraubteil 11 heraus. Vorzugsweise bringt er das Mundstück 7 bereits vor Beginn seiner Fahrt in die Zwischenstellung, damit durch die Erwärmung des Flascheninhaltes durch Sonnenbestrahlung kein Überdruck in der Flasche 1 entstehen kann. Beim vollständigen Herausziehen des Mundstückes 7 wird das untere Ende des zylindrischen Abschnittes 31 des Mundstückes 7 aus dem Zapfen 19 herausgezogen und eine Verbindung zwischen dem Flascheninnern über die unten offene Erweiterung 17 zur Saugbohrung 29 geschaffen und ein Austritt von Flüssigkeit aus der Flasche 1 ermöglicht.If the cyclist intends to drink from the bottle 1, he pulls the mouthpiece 7 axially out of the screw part 11 either by hand or after attaching the mouthpiece 7 to the mouth with his teeth. Preferably, he brings the mouthpiece 7 into the intermediate position before the start of his journey, so that the bottle 1 cannot be overpressurized by heating the contents of the bottle due to solar radiation. When the mouthpiece 7 is completely pulled out, the lower end the cylindrical section 31 of the mouthpiece 7 is pulled out of the pin 19 and a connection between the inside of the bottle is created via the extension 17, which is open at the bottom, to the suction bore 29 and allows liquid to escape from the bottle 1.

Damit in der Flasche 1 auch bei der Entnahme von Flüssigkeit kein Unterdruck entsteht, kann Luft aus der Atmosphäre durch den nun erweiterten offenen Querschnitt im Belüftungskanal 21 in die Flasche 1 eintreten. Der Belüftungskanal 21, welcher sich innerhalb der Ausnehmung 23 befindet, wird durch das Herausziehen des Mundstückes 7 und des Domes 30 aus dem Schraubteil 11 weiter freigelegt und erlaubt dadurch den Zutritt von Luft in genügender Menge.So that there is no negative pressure in the bottle 1 even when liquid is removed, air can enter the bottle 1 from the atmosphere through the now widened open cross section in the ventilation channel 21. The ventilation channel 21, which is located within the recess 23, is further exposed by pulling the mouthpiece 7 and the dome 30 out of the screw part 11 and thereby allows air to be admitted in sufficient quantity.

Nach dem Gebrauch kann das Mundstück 7 wieder, noch im Mund des Radfahrers, in den Schraubteil 11 eingeschoben werden und damit auch ein Auslaufen von Flüssigkeit beim Absetzen der Flasche 1 vom Mund sicher verhindert werden.After use, the mouthpiece 7 can again be inserted into the screw part 11, still in the cyclist's mouth, and thus leakage of liquid when the bottle 1 is removed from the mouth can be reliably prevented.
