Description

Die Erfindung betrifft eine Kappe für Behältnisse, insbesondere im Blasverfahren aus Kunststoff hergestellte und in der Form gefüllte sowie verschlossene Flaschen, welche die Merkmale des Oberbegriffes des Anspruches 1 aufweist.The invention relates to a cap for containers, in particular in the blow molding process made of plastic and filled and closed in the mold, which has the features of the preamble of claim 1.

Für Flaschen aus Kunststoff, deren mit einem Außengewinde versehener Hals an seinem freien Ende durch ein einstückig mit dem Hals ausgebildetes Verschlußteil verschlossen ist, ist es bekannt, eine auf den Hals aufgeschraubte Kappe innen mit einem zentral angeordneten Dorn zu versehen, mit dem das Verschlußteil durchstoßen werden kann. Wird nach dem Durchstoßen des Verschlußteils die Kappe abgenommen, dann kann durch die im Verschlußteil gebildete Öffnung die sich in der Flasche befindende Flüssigkeit abgegeben werden. Abgesehen davon, daß es bei einem nicht optimal ausgeformten Gewinde des Flaschenhalses und/oder der Kappe oder auch einem nicht optimal ausgeformten Dorn dazu kommen kann, daß die mit dem Dorn eingestochene Öffnung schräg bezüglich der Längsachse verläuft, oder daß nach einer Entnahme einer Teilmenge und einem anschließenden Aufschrauben der Kappe eine zweite Öffnung eingestochen wird, was zur Folge hat, daß die Flüssigkeit in einer von der Längsachse abweichenden Richtung gegebenenfalls an mehreren Stellen austritt, was störend ist, hängt es von dem auf die Flüssigkeit ausgeübten Druck ab, ob die Flüssigkeit in mehr oder weniger großen Tropfen oder in Form eines Strahles abgegeben wird. Ferner kann sich die Größe der Öffnung im Laufe der Zeit verändern, wenn nach Entnahme einer Teilmenge des Flascheninhaltes der Hals mit der Kappe wieder verschlossen und dabei der Dorn wieder in die Öffnung eingeführt wird. Es ist deshalb schwierig, die zu entnehmende Menge richtig zu dosieren.For plastic bottles, the neck of which is provided with an external thread and is closed at its free end by a closure part formed in one piece with the neck, it is known to provide a cap screwed onto the neck with a centrally arranged mandrel with which the closure part penetrates can be. If the cap is removed after the cap has been pierced, the liquid in the bottle can be dispensed through the opening formed in the cap. Apart from the fact that if the thread of the bottle neck and / or the cap is not optimally shaped, or even if the mandrel is not optimally shaped, the thread pierced with the mandrel can occur Opening runs obliquely with respect to the longitudinal axis, or that after removal of a partial quantity and subsequent screwing on of the cap, a second opening is pierced, with the result that the liquid may escape at several points in a direction deviating from the longitudinal axis, which is annoying , it depends on the pressure exerted on the liquid whether the liquid is released in more or less large drops or in the form of a jet. Furthermore, the size of the opening can change in the course of time if, after a portion of the bottle content has been removed, the neck is closed again with the cap and the mandrel is then reinserted into the opening. It is therefore difficult to dose the correct amount correctly.

Eine bekannte Kappe der eingangs genannten Art (DE-C-38 18 629) deckt einen Tropfereinsatz ab, der mit einem ringförmigen, hohlzylindrischen Kragen in den Hals der Flasche eingreift. Für eine Flasche, deren Hals bis zur erstmaligen Entnahme mit einem zu entfernenden oder zu durchstoßenden Verschlußteil verschlossen ist, kommt ein solcher Tropfereinsatz nicht in Frage, dessen Durchlaßkanal aus einem sich in der Ausfließrichtung konisch verjüngenden ersten Abschnitt, einem sich an diesen anschließenden, zylindrischen zweiten Abschnitt, dessen Durchmesser etwa gleich seiner axialen Länge und wesentlich kleiner ist als derjenige des ersten Abschnittes, einem sich in der Ausfließrichtung konisch erweiternden dritten Abschnitt und einem sich an letzteren anschließenden, zylindrischen vierten Abschnitt besteht.A known cap of the type mentioned (DE-C-38 18 629) covers a dropper insert which engages with an annular, hollow cylindrical collar in the neck of the bottle. For a bottle whose neck is closed with a closure part to be removed or pierced until it is first removed, such a dropper insert is out of the question, the passage channel of which consists of a tapering conically in the outflow direction, a cylindrical second adjoining it Section, the diameter of which is approximately equal to its axial length and substantially smaller than that of the first section, a third section which widens conically in the outflow direction and a cylindrical fourth section adjoining the latter.

Bei einer anderen bekannten Kappe (WO 82/00348) für eine Flasche schließt sich einstückig an den den Hals aufnehmenden Abschnitt ein eine Stirnfläche bildender Übergangsabschnitt an, mit dem einstückig eine Spritzdüse ausgebildet ist. Diese Kappe legt eine in die Flasche eingesetzte Dosiervorrichtung mit einem Kugelventil fest, das es ermöglicht, den Inhalt der Flasche in Form eines dosierten Strahles abzugeben.In another known cap (WO 82/00348) for a bottle, a transition section forming an end face adjoins the section receiving the neck, with which a spray nozzle is formed in one piece. This cap defines a dosing device inserted into the bottle with a ball valve, which makes it possible to dispense the contents of the bottle in the form of a dosed jet.

Der Erfindung liegt die Aufgabe zugrunde, eine problemlose Entnahme des flüssigen Inhalts von Flaschen in Form von einzelnen Tropfen definierter Größe zu ermöglichen. Diese Aufgabe löst eine Kappe mit den Merkmalen des Anspruches 1.The invention has for its object to enable easy removal of the liquid content of bottles in the form of individual drops of a defined size. This object is achieved by a cap having the features of claim 1.

Dank des als Tropfer ausgebildeten Abschnittes der erfindungsgemäßen Kappe erfolgt die Dosierung bei der Abgabe des flüssigen Inhalts der Flasche nicht mittels einer vom Flaschenhals gebildeten Öffnung, sondern mittels des Tropfers der Kappe. Dieser Tropfer kann problemlos so ausgebildet werden, daß er unabhängig von dem herrschenden Druck Tropfen reproduzierbarer Größe bildet und dann zuverlässig die Abgabe in Form eines Strahles ausschließt.Thanks to the portion of the cap according to the invention designed as a dropper, the dispensing of the liquid content of the bottle is not carried out by means of an opening formed by the bottle neck, but by means of the dropper of the cap. This dropper can easily be designed so that it forms drops of reproducible size regardless of the prevailing pressure and then reliably excludes the discharge in the form of a jet.

Damit die erfindungsgemäße Kappe für Flaschen, beispielsweise Ampullen, verwendbar ist, welche ein zunächst mit einer Durchlaßöffnung zu versehendes Verschlußteil haben, ist am Übergang der Kappe von dem den Hals aufnehmenden Abschnitt zu dem als Tropfer ausgebildeten Abschnitt eine Stirnfläche vorgesehen, an die ein gegen die Flasche hin vorspringender Dorn angeformt ist, in dem der Durchlaßkanal des Tropfers beginnt. Das Verschlußteil kann dann wie bei den bekannten Kappen mit Dorn mittels des Dorns durchstoßen werden. Da die Dosierung der Tropfer ausführt, ist es in diesem Falle ohne Bedeutung, ob die Öffnung im Verschlußteil genau zentrisch und koaxial gebildet wird und ob ihre Größe vom Sollwert abweicht.So that the cap according to the invention can be used for bottles, for example ampoules, which have a closure part which is initially to be provided with a passage opening, an end face is provided at the transition of the cap from the portion receiving the neck to the portion designed as a dropper, against which a Bottle protruding mandrel is formed, in which the passage channel of the dropper begins. The closure part can then be pierced by means of the mandrel as in the known caps with mandrel. Since the dropper is dosed, it is irrelevant in this case whether the opening in the closure part is formed exactly in the center and coaxially and whether its size deviates from the nominal value.

Damit der Dorn eine scharfe Spitze haben kann, weist der Durchlaßkanal des Tropfers wenigstens zwei in der Mantelfläche des Dornes mündende Endabschnitte auf, die innerhalb des Flaschenhalses zu liegen kommen, wenn die Kappe vollständig auf den Hals aufgesetzt ist.In order that the mandrel can have a sharp tip, the passage channel of the dropper has at least two end sections opening into the lateral surface of the mandrel, which end portions lie within the bottle neck when the cap is completely placed on the neck.

Eine sehr gute Reproduzierbarkeit der Tropfengröße und eine zuverlässige Verhinderung einer strahlförmigen Abgabe des Flascheninhaltes erreicht man mit einem Durchlaßkanal des Tropfers, der im Anschluß an einen zylindrischen Abschnitt einen sich in der Ausfließrichtung konisch erweiterten Abschnitt aufweist. Vorzugsweise werden diese Abschnitte bei der Herstellung mittels eines Kalibrierdornes kalibriert.A very good reproducibility of the droplet size and a reliable prevention of a jet-like delivery of the bottle contents can be achieved with a passage channel of the dropper which, following a cylindrical section, has a section which widens conically in the outflow direction. These sections are preferably calibrated during manufacture by means of a calibration mandrel.

Es ist zwar auch möglich, die Kappe so ausbilden, daß sie unter Bildung eines Schiebesitzes auf dem Hals angeordnet werden kann. In der Regel wird man jedoch den den Hals aufnehmenden Abschnitt der Kappe mit einem Innengewinde versehen, das korrespondierend zu einem Außengewinde des Halses ausgebildet ist.It is also possible to design the cap so that it can be arranged on the neck with the formation of a sliding seat. As a rule, however, the portion of the cap receiving the neck will be provided with an internal thread which is designed to correspond to an external thread of the neck.

Bei einer bevorzugten Ausführungsform ist ein auf den als Tropfer ausgebildeten Abschnitt abnehmbar aufgesetztes Verschlußteil vorgesehen, damit der Durchlaßkanal des Tropfers geschützt ist. Vorzugsweise ist dieses Verschlußteil als eine topfförmige Haube mit einem Innengewinde ausgebildet, das mit einem Außengewinde des als Tropfer ausgebildeten Abschnittes korrespondiert. An die Innenfläche des Bodens dieser Haube kann zentrisch ein Zapfen angeformt sein, der dichtend in den Durchlaßkanal des Tropfers einführbar ist.In a preferred embodiment, a closure part is provided so that it can be removed from the section designed as a dropper, so that the passage channel of the dropper is protected. This closure part is preferably designed as a cup-shaped hood with an internal thread which corresponds to an external thread of the section designed as a dropper. A spigot can be formed centrally on the inner surface of the bottom of this hood, which can be inserted in a sealing manner into the passage channel of the dropper.

Im folgenden ist die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels im einzelnen erläutert.The invention is based on one in the drawing illustrated embodiment explained in detail.

Die einzige Ausführungsform zeigt im vergrößerten Maßstab und teilweise im Längsschnitt das Ausführungsbeispiel in dem auf den Hals einer Flasche aufgesetzten Zustand vor dem Durchstoßen des Verschlußteiles des Halses.The only embodiment shows, on an enlarged scale and partly in longitudinal section, the embodiment in the state placed on the neck of a bottle before the closure part of the neck is pierced.

Eine als Ganzes mit 1 bezeichnete Kappe aus Kunststoff weist, wie die Figur zeigt, einen ersten, hohlzylindrischen Abschnitt 2 auf, welcher der Aufnahme des Halses 3 einer Flasche dient, die im Ausführungsbeispiel aus Kunststoff im Blasformverfahren hergestellt und in der Blasform gefüllt sowie verschlossen worden ist, wobei das den Hals 3 verschließende, plattenförmige Verschlußteil 4 einstückig mit dem Hals 3 ausgebildet ist. Der Hals 3 der Flasche, bei der es sich um eine Ampulle handeln kann, ist mit einem Außengewinde 5 versehen. Zwischen dem Flaschenkörper 3' und dem diesem näherliegenden Ende des Außengewindes 5 weist der Hals 3 einen zylindrischen Abschnitt 6 auf, dessen Außendurchmesser gleich demjenigen des Außengewindes 5 gewählt ist. An das dem Flaschenkörper 3' zugewandte Ende des zylindrischen Abschnittes 6 schließt sich ein geringfügig über diesen Abschnitt radial nach außen überstehender Ringwulst 7 an. Der Durchmesser dieses Ringwulstes 7 ist geringfügig größer als der Innendurchmesser der das freie Ende des Abschnittes 2 bildenden Zone.A plastic cap designated as a whole as 1 has, as the figure shows, a first, hollow cylindrical section 2, which serves to accommodate the neck 3 of a bottle which, in the exemplary embodiment, was made from plastic in the blow molding process and was filled and closed in the blow mold is, the plate-shaped closure part 4 closing the neck 3 being formed in one piece with the neck 3. The neck 3 of the bottle, which can be an ampoule, is provided with an external thread 5. Between the bottle body 3 'and the end of the external thread 5 closer to it, the neck 3 has a cylindrical section 6, the external diameter of which is selected to be equal to that of the external thread 5. At the end of the cylindrical section 6 facing the bottle body 3 ', there is an annular bead 7 projecting slightly beyond this section. The diameter of this annular bead 7 is slightly larger than the inner diameter of the zone forming the free end of section 2.

Der Abschnitt 2 ist mit einem Innengewinde versehen, das mit dem Außengewinde 5 des Halses 3 korrespondiert, sich aber nicht in die den freien Endabschnitt bildende Zone hinein erstreckt. An den Abschnitt 2 schließt sich auf der dem Flaschenkörper 3' abgewandten Seite gleichachsig und einstückig ein als Tropfer 8 ausgebildeter Abschnitt an, der mit einem Außengewinde 9 versehen ist und dessen freies Ende halbkugelförmig abgerundet ist. An die am Übergang vom Abschnitt 2 zum Tropfer 8 vorhandene, innenliegende Stirnfläche 8' des Tropfers 8 ist in deren Zentrum ein kegelförmger Dorn 10 angeformt, dessen Spitze in das Innere des Abschnittes 2 weist. In der Mantelfläche dieses Dornes 10 münden Endabschnitte 11 des im übrigen gleichachsig zum Dorn 10 den Tropfer 8 durchdringenden Durchlaßkanales, der im Anschluß an die Endabschnitte 11 einen zylindrischen Mittelabschnitt 12 und im Anschluß an diesen einen sich zum halbkugelförmigen Ende des Tropfers 8 erweiternden, konischen Abschnitt 13 aufweist. Sowohl der Mittelabschnitt 12 als auch der konische Abschnitt 13 werden bei der Herstellung mittels eines Kalibrierdornes kalibriert. Wie die Figur zeigt, ist der Durchmesser des Mittelabschnittes 12 wesentlich kleiner als seine axiale Länge, was auch für den konischen Abschnitt 13 gilt, der einen relativ kleinen Konuswinkel hat. Im Ausführungsbeispiel beträgt er etwa 8°. Die Ausgestaltung des Durchlaßkanales und insbesondere seiner beider Abschnitte 12 und 13 kann auch anders gewählt werden müssen, da sie von den Eigenschaften der Flüssigkeit, beispielsweise deren Viskosität und Oberflächenspannung, sowie von der Tropfengröße und davon abhängt, ob eine Abgabe in Tropfenform oder in Form eines Strahles gewünscht wird.The section 2 is provided with an internal thread which corresponds to the external thread 5 of the neck 3, but does not extend into the zone forming the free end section. The section 2 is adjoined on the side facing away from the bottle body 3 ', coaxially and in one piece, by a section designed as a dropper 8, which is provided with an external thread 9 and whose free end is rounded off in a hemispherical manner. A conical mandrel 10 is formed in the center of the inner end face 8 ′ of the dropper 8 present at the transition from the section 2 to the dropper 8, the tip of which points into the interior of the section 2. In the outer surface of this Mandrel 10 open end portions 11 of the passage channel which penetrates the dropper 8 coaxially with the mandrel 10 and which has a cylindrical central portion 12 following the end portions 11 and a conical portion 13 which widens towards the hemispherical end of the dropper 8. Both the central section 12 and the conical section 13 are calibrated during manufacture by means of a calibration mandrel. As the figure shows, the diameter of the central section 12 is significantly smaller than its axial length, which also applies to the conical section 13, which has a relatively small cone angle. In the exemplary embodiment, it is approximately 8 °. The design of the passage channel and in particular its two sections 12 and 13 can also be chosen differently, since it depends on the properties of the liquid, for example its viscosity and surface tension, as well as on the drop size and whether it is delivered in drop form or in the form of a Beam is desired.

Zur Abdeckung des Tropfers 8 ist eine topfförmige Schutzhaube 14 vorgesehen, die wie die Kappe 1 aus Kunststoff besteht. Die Schutzhaube 14 ist mit einem mit dem Außengewinde des Tropfers 8 korrespondierende Innengewinde versehen und erstreckt sich nahezu bis an die am Übergang vom Abschnitt 2 zum Tropfer 8 gebildete Außenschulter der Kappe 1. Wie die Figur zeigt, ist im Zentrum des Bodens der Schutzhaube 14 an dessen Innenseite ein Zapfen 15 einstückig angeformt, welcher in den konischen Abschnitt 13 eingreift und diesen dicht verschließt, wenn die Schutzhaube 14 vollständig auf den Tropfer 8 aufgeschraubt ist.To cover the dropper 8, a cup-shaped protective hood 14 is provided which, like the cap 1, is made of plastic. The protective hood 14 is provided with an internal thread corresponding to the external thread of the dropper 8 and extends almost up to the outer shoulder of the cap 1 formed at the transition from the section 2 to the dropper 8. As the figure shows, the protective hood 14 is in the center of the bottom the inside of which a pin 15 is integrally formed, which engages in the conical section 13 and closes it tightly when the protective hood 14 is screwed completely onto the dropper 8.

Sofern die Flasche mit der Kappe 1 auf den Markt kommt, ist die Kappe 1 so weit auf den Hals 3 aufgeschraubt, daß sich das freie Ende des Abschnittes 2 bis zu dem Ringwulst 7 des Halses 3 erstreckt, wie dies die Figur zeigt. Diese Position ist daran leicht zu erkennen, daß dann, wenn die Kappe 1 noch weiter auf den Hals 3 aufgeschraubt wird, der Abschnitt 2 in Anlage an den Ringwulst 7 kommt und damit ein erhöhtes Drehmoment aufgebracht werden muß. Der Dorn 10 befindet sich, wenn die Kappe 1 bis zum Ringwulst 7 auf den Hals 3 aufgeschraubt ist, in Anlage oder nahezu in Anlage am Verschlußteil 4. Wenn nunmehr der Inhalt der Flasche entnommen werden soll, wird die Kappe 1 vollständig auf den Hals 3 aufgeschraubt. Da hierbei der Dorn 10 das Verschlußteil 4 durchstößt und außerdem der Ringwulst 7 überwunden werden muß, muß ein deutlich spürbar erhöhtes Drehmoment aufgebracht werden, was jedoch dank der Längsriffelung der Außenmantelfläche des Abschnittes 2 keine Schwierigkeiten bereitet. Wenn der Dorn 10 vollständig den Verschlußteil 4 durchstoßen hat, liegt dessen äußere Stirnfläche an der den Dorn 10 tragenden Stirnfläche 8' des Tropfers 8 an. Außerdem münden die Endabschnitte 11 des Durchlaßkanales des Tropfers in dem Innenraum des Halses 3. Nunmehr braucht nur noch die Schutzhaube 14 abgeschraubt zu werden, um den Inhalt der Flasche in Form von einzelnen Tropfen definierter, reproduzierbarer Größe oder, falls der Durchlaßkanal für eine Flüssigkeitsabgabe in Form eines Strahles definierter Größe ausgebildet ist, in Form eines Strahles entnehmen zu können.If the bottle with the cap 1 comes onto the market, the cap 1 is screwed onto the neck 3 so far that the free end of the section 2 extends up to the annular bead 7 of the neck 3, as the figure shows. This position can be easily recognized from the fact that when the cap 1 is screwed even further onto the neck 3, the section 2 comes into contact with the annular bead 7 and thus an increased torque is applied must become. When the cap 1 is screwed onto the neck 3 up to the annular bead 7, the mandrel 10 is in contact or almost in contact with the closure part 4. When the contents of the bottle are now to be removed, the cap 1 is completely on the neck 3 screwed on. Since in this case the mandrel 10 pierces the closure part 4 and the annular bead 7 also has to be overcome, a clearly noticeably increased torque must be applied, but this does not cause any difficulties thanks to the longitudinal corrugation of the outer surface area of the section 2. When the mandrel 10 has completely penetrated the closure part 4, its outer end face rests on the end face 8 ′ of the dropper 8 that supports the mandrel 10. In addition, the end portions 11 of the through-channel of the dropper open into the interior of the neck 3. Now only the protective hood 14 needs to be unscrewed in order to remove the contents of the bottle in the form of individual drops of a defined, reproducible size or, if the through-channel for dispensing liquid in Shape of a beam of a defined size is formed, can be removed in the form of a beam.
