Definitions
- the invention relates to a safety rotary closure for a multi-chamber bottle, in particular for a two-chamber bottle, with separate pour spouts according to the preamble of patent claim 1.
- substances are often used, which consist of separate components.
- the substances are detergents or agents for use in gardening or agriculture, which consist of at least two flowable or liquid individual components, which must be stored separately from each other and only come into contact with each other during pouring.
- multi-chamber bottles, in particular of plastic are known from the prior art, which are manufactured in one or more parts.
- multi-chambered bottles In order to prevent the individual components from coming into contact with each other too early, besides the multi-chamber bottles with a common pouring opening for the chambers, also multi-chambered bottles, usually two-chambered bottles, are known, which have a separate pouring spout for each chamber with its own pouring opening. It is known to provide the separate pouring with separate closures, such as screw caps.
- a canister-type two-chamber container which has a pour spout with two pouring openings.
- the outer wall of the common Ausgiessstutzens is provided with an external thread. After attaching separate sealing plugs for the pouring openings, a screw cap can be screwed onto the common pouring spout.
- each individual screw cap can be provided with a child safety device.
- a closure cap for a multi-chamber bottle in particular a two-chamber bottle, which can be screwed onto the common bottle neck of the multi-chamber bottle.
- the rotary closure has a sealing membrane arranged inside the closure, which is pressed against the mouth edges of the pouring openings when the closure is screwed on.
- the sealing of the pouring openings via the sealing membrane is often insufficient.
- the object of the present invention is therefore to eliminate the disadvantages of safety turning closures for multi-chamber bottles, in particular of two-arm bottles. It is to be created a security turning lock, which also after repeated opening and closing closes the pouring openings reliably.
- the handling of the safety rotary closure should still be simple and self-explanatory.
- the closure should have a simple structure and be inexpensive to manufacture. The need to produce a separate series of bottles for the application of the safety rotary closure should be omitted.
- the invention proposes a safety rotary closure for a multi-chamber bottle, in particular for a two-chamber bottle, which has a separate pour spout for each chamber with a pouring opening and has a rotary closure which can be screwed onto a common neck portion of the multi-chamber bottle.
- the safety rotary closure is equipped with a mechanically acting child safety device against unauthorized release of the closure and has substantially conical sealing parts which engage in the spouted openings in the Ausgiessstutzen and sealingly cooperate with the inner walls of the Ausgiessstutzen. All locking elements of the child safety device are arranged on the safety rotary closure.
- conical sealing parts By providing conical sealing parts, the problem of abrasive wear of sealing membranes or similar disc-like sealing elements is eliminated.
- the conical sealing parts slide axially into the pouring openings and are pressed by the closing pressure against the inner walls of the pouring spouts. Upon release of the closure, the conical seal parts slide axially out of the pouring out. The risk of abrasive wear of the sealing surfaces and the opening edges is eliminated.
- By arranging all locking elements of the child-safety device on the safety rotary closure eliminates the need for a separate production bottles with arranged on the bottle neck locking elements. Whether the bottle has to be equipped with a safety turning cap is decided on the basis of the components to be filled. The production of the type of multi-chamber bottle is largely independent of this. This leads to a reduction in the necessary molds for the bottle producers. The quantities of the affected multi-chamber bottles can be significantly increased, which has a very beneficial effect on the economics of production.
- the combination of a safety rotary closure with conical sealing parts is realized in a suitable embodiment of the invention by a two-part construction.
- the safety turning cap consists of an overcap and a sealing insert.
- the overcap has a top surface and a cylinder wall projecting therefrom, the inner surface of which is provided in regions with threaded portions.
- the sealing insert is rotatably and axially displaceably held in the cover.
- the conical sealing parts protrude from the top surface of the overcap facing away bottom of the sealing insert.
- the separate sealing insert increases the flexibility of the safety turning cap. In particular, it is possible, depending on the nature of the ingredients of the multi-chamber bottle sealing inserts made of different materials in the cover to use.
- the overcap may for example be made as a standard part, which can be screwed onto a multi-chamber bottle with a correspondingly uniform diameter of the common neck part.
- a corresponding sealing insert with two or three sealing parts projecting from the underside can be inserted into the overcap.
- the overcap can be produced in a much larger number, which also significantly increases the economy of the lid production.
- a variant of the safety turning closure provides that the securing parts of two projections on the cover and two corresponding locking cam on Seal insert are formed.
- the two projections protrude from opposite portions of the inner surface of the cylinder wall and are hook-like curved in the direction of the top surface of the cover. They are arranged at an axial distance from the top surface, which is greater than an axial height of the sealing insert.
- the two hook-like projections support the sealing insert on the one hand axially and on the other hand cooperate with the corresponding locking cam, which protrude from the underside of the sealing insert.
- the sealing insert is simply pressed into the cover. He slides behind the hook-like projections, which prevent him from falling out of the cover again.
- the sealing insert is axially and radially freely movable in the cover.
- the sealing insert When screwing in the turn-lock cap, the sealing insert is turned along until its conical sealing parts slide into the pouring openings. As a result, further co-rotation of the sealing insert is prevented.
- the cover over the sealing insert Upon further screwing the cover over the sealing insert is rotated and is also moved axially relative to this in the direction of the bottle. Finally, the top surface of the cover abuts the sealing part and presses the conical sealing parts further into the pouring openings.
- the locking cams are wedge-shaped in the circumferential direction with advantage.
- the wedge-shaped locking cams facilitate the relative rotatability of the cover and the sealing insert when the safety turning lock is screwed on.
- the cooperating locking cam and the hook-like projections lock and prevent relative rotation of the lid member relative to the sealing insert.
- the locking of the safety rotary closure against opening results from the prevention of the relative rotation of the cover part relative to the sealing insert and the blocking effect of the conical sealing parts projecting into the pouring opening.
- An advantageous embodiment of the safety turning closure provides that the projections on the inner surfaces of oppositely arranged flap portions of the cover arranged are.
- the tab portions provided in the cylinder wall of the cover are radially elastically adjustable by pressure.
- the flap portions By compressing the flap portions, the projections are moved inwardly and the locking cams can slide through the gap between the cylinder wall and the hook-like curved projections.
- the rotation lock is released and the lid can be rotated relative to the sealing insert.
- the sealing insert rests on the projections of the overcap, it is lifted off the pouring openings when the lid is screwed on further.
- the conical sealing parts slide out of the pouring openings the sealing insert can turn again with the overcap. Further compression of the flap sections is then no longer necessary.
- the flap sections are advantageously provided on their outer surfaces at least partially with a corrugation.
- the centering pin protrudes into the recess between the spout of the bottle and facilitates positioning. During the screwing of the safety turning cap, the centering pin slides into the recess between the pouring spouts.
- the centering pin is hollow and designed to receive a projecting from the top surface of the overcap guide pin.
- the guide pin further improves the free position of the sealing insert in the cover and prevents any tilting of the sealing insert.
- Another embodiment of the safety turning closure which also consists of only two parts which are easy to assemble with each other, comprises an overcap, which has a top surface and a cylinder wall projecting therefrom, the inner surface of which is provided in regions with threaded portions, and a sealing insert which is rotatably held in the overcap, essentially a hat-shaped design. From the top surface of the overcap facing away underside of the hat-shaped sealing insert protrude the conical seal parts.
- the hat-shaped sealing insert has a brim-like edge portion on which at least one locking cam is formed, which cooperates with at least one corresponding locking member of the cover.
- Each locking cam is wedge-shaped in the closed direction of rotation. This facilitates the relative rotation of the cover and the sealing insert in the closed direction of rotation over sliding of the locking members of the cover over the locking cams. In the opposite relative direction of rotation, each locking cam on a locking surface, which forms an abutment for the locking member of the cover.
- two locking cams are provided, which are formed approximately diagonally opposite each other at the edge portion of the sealing insert and cooperate with a corresponding number of locking members on the cover.
- the corresponding locking members on the cover are formed by flap portions which are integrally formed on the cover and are radially elastically adjustable by pressure.
- the tab portions are provided on their outer side at least partially with a corrugation.
- the sealing insert in the cover is supported on one or more projections which project from the inner surface of the cylinder wall of the cover and has a smaller distance from the top surface or have as the threaded portions.
- the projection or projections are very easy to produce integrally with the cover.
- the sealing insert is simply pressed into the overcap until it slides over the projection (s) and is axially supported thereon.
- the sealing insert is held axially immovably in the overcap. This can be done for example by an axial clamping of the sealing insert between axially spaced projections in the cover.
- the sealing insert has the hat-like sealing insert to a height that corresponds to the distance of the or the projections of the top surface of the cover substantially. After its installation, the sealing insert abuts against the top surface of the cover and is therefore no longer axially displaceable.
- the axial inability to move the sealing insert allows to provide a very simple embodiment of an over-rotation.
- the over-rotation lock is formed by at least one, formed on the brim-like edge portion of the sealing insert wing portion. From the underside of the wing section, an extension projects axially such that the wing section is axially elastically displaceable when the safety rotary lock is screwed onto the multichamber bottle and forms an abutment for the blocking element, in particular the flap section, formed on the cover. As soon as the flap section abuts against the wing section which is pressed up, a further relative rotation of the cover over the sealing insert is prevented. As a result, the safety twist lock can not be over-tightened.
- the wing portion is arranged in the closing direction of rotation after the locking cam and has the locking cam on a distance which is greater than a measured width in the circumferential direction of the locking member, in particular of the tab portion on the cover.
- the flap section To open the safety twist lock, the flap section must be pressed inwards until its free end protrudes further into the interior of the cover than the locking cam. Only in this position, a relative rotation between the cover and the sealing insert and thus unscrewing the safety rotary closure is possible.
- two wing sections are also provided, which lie approximately diametrically opposite one another at the edge section of the sealing insert.
- a wing section by making a radially and circumferentially extending cut in the brim-like edge section.
- the wing portion formed thereby is hingedly connected to the edge portion.
- the inventive safety twist lock is designed for multi-chamber bottles with two or more chambers with separate pour spouts and pouring openings.
- the safety rotary closure for two-chambered bottles is formed and it has two opposing conical sealing parts.
- the size of the sealing parts is matched to the conventional dimensions of the pouring of two-chamber bottles. It eliminates the need for a separate bottle production, which is tuned to the selected safety turning cap.

At two opposite portions of the cylinder wall 14 protrude from projections 15 which are curved like a hook and extending in the direction of the top surface 13. The axial distance between the free ends of the hook-like curved projections 15 and the top surface 13 is slightly larger than the axial height of the sealing insert 12. The projections 15 are arranged on flap portions 18, each by two axial and one radial cut in the cylinder wall 14 and ., The top surface 13 of the cover 11 are created. The tab portions 18 are formed radially elastically federbar. On its outside, the tab portions 18 are at least partially provided with a corrugation.
- the sealing insert 12 is equipped on its underside 22 with conical sealing parts 20.
- the conical sealing parts 20 have by means of incisions separate sealing blades 24.
- the overcap 11 and the sealing insert 12 are preferably made in a plastic injection molding process from plastic, for example polypropylene, polyethylene, HDPE, etc. To ensure the relative rotatability and the axial mobility of the overcap 11 and the sealing insert 12 are usually made of different plastics. Alternatively, they may also be provided with a lubricious coating on the sliding areas.
- Fig. 2 shows the composite safety twist lock 1 in the screwed-on state.
- the sealing insert 12 is inserted into the overcap 11. In this case, its side wall slides over the hook-like projections 15, which prevent the sealing insert 12 from falling out again.

Abstract
Description
Die Erfindung betrifft einen Sicherheitsdrehverschluss für eine Mehrkammerflasche, insbesondere für eine Zweikammerflasche, mit separaten Ausgiessstutzen gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a safety rotary closure for a multi-chamber bottle, in particular for a two-chamber bottle, with separate pour spouts according to the preamble of
Im Haushalt und in der gewerblich-industriellen Anwendung kommen vielfach Substanzen zur Anwendung, die aus separaten Komponenten bestehen. Beispielsweise handelt es sich bei den Substanzen um Reinigungsmittel oder um Mittel für den Einsatz in der Gartenpflege oder auch in der Landwirtschaft, die aus wenigstens zwei fliessfähigen bzw. flüssigen Einzelkomponenten bestehen, welche getrennt voneinander aufbewahrt werden müssen und erst beim Ausgiessen miteinander in Berührung kommen. Dabei besteht der Bedarf, die Einzelkomponenten in einem einheitlichen Behälter unterzubringen, der mehrere Kammern aufweist. Zu diesem Zweck sind aus dem Stand der Technik Mehrkammerflaschen, insbesondere aus Kunststoff, bekannt, die ein- oder mehrteilig hergestellt sind.In the household and in the industrial-industrial application substances are often used, which consist of separate components. For example, the substances are detergents or agents for use in gardening or agriculture, which consist of at least two flowable or liquid individual components, which must be stored separately from each other and only come into contact with each other during pouring. There is a need to accommodate the individual components in a single container having a plurality of chambers. For this purpose, multi-chamber bottles, in particular of plastic, are known from the prior art, which are manufactured in one or more parts.
Um zu verhindern, dass die einzelnen Komponenten zu früh miteinander in Kontakt kommen, sind neben den Mehrkammerflaschen mit einer gemeinsamen Ausgiessöffnung für die Kammern auch Mehrkammerflaschen, üblicherweise Zweikammerflaschen, bekannt, die für jede Kammer einen separaten Ausgiessstutzen mit einer eigenen Ausgiessöffnung aufweisen. Es ist bekannt, die separaten Ausgiessöffnungen mit separaten Verschlüssen, beispielsweise Drehverschlüssen, zu versehen.In order to prevent the individual components from coming into contact with each other too early, besides the multi-chamber bottles with a common pouring opening for the chambers, also multi-chambered bottles, usually two-chambered bottles, are known, which have a separate pouring spout for each chamber with its own pouring opening. It is known to provide the separate pouring with separate closures, such as screw caps.

Wegen des oft basischen oder sauren Inhalts der Mehrkammerflaschen oder im Fall anderer problematischer Inhalte besteht vielfach der Wunsch, derartige Flaschen kindersicher zu verschliessen. Prinzipiell kann daher jeder einzelne Drehverschluss mit einer Kindersicherung versehen sein. Allerdings ist eine derartige Lösung im Gebrauch wenig benutzerfreundlich. Aus dem Stand der Technik ist daher auch bereits eine Verschlusskappe für eine Mehrkammerflasche, insbesondere eine Zweikammerflasche, bekannt, die auf den gemeinsamen Flaschenhals der Mehrkammerflasche aufschraubbar ist. Der Drehverschluss weist eine innerhalb des Verschlusses angeordnete Dichtmembran auf, die beim Aufschrauben des Verschlusses gegen die Mündungsränder der Ausgiessöffnungen gepresst wird. Die Abdichtung der Ausgiessöffnungen über die Dichtmembran ist leider oft nur ungenügend. Beim Zu- und Abschrauben des Drehverschlusses reiben die Öffnungsränder gegen die Dichtfläche der Dichtmembran. Dadurch kann es zu einer Abnutzung der Dichtmembran kommen, welche dann nicht mehr richtig schliesst. Die Kindersicherung dieses bekannten Drehverschlusses besteht in einer formschlüssigen Verriegelung von am Verschluss angeordneten Verriegelungselementen mit entsprechend ausgebildeten Gegenstücken am Flaschenhals. Dies bedingt, das Flaschen, die mit einem kindersicheren Verschluss ausgestattet werden sollen, separat hergestellt werden müssen. Aus produktionstechnischen Gründen und um die Kosten niedrig zu halten, wäre es jedoch wünschenswert, wenn die gleiche Mehrkammerflasche einerseits für die Abfüllung problemloser Inhalte und andererseits auch für solche Inhaltsstoffe, die einen kindersicheren Verschluss bedingen, einsetzbar wäre.Because of the often basic or acidic content of the multi-chamber bottles, or in the case of other problematic contents, there is often the desire to close such bottles childproof. In principle, therefore, each individual screw cap can be provided with a child safety device. However, such a solution is not very user-friendly in use. The prior art therefore already discloses a closure cap for a multi-chamber bottle, in particular a two-chamber bottle, which can be screwed onto the common bottle neck of the multi-chamber bottle. The rotary closure has a sealing membrane arranged inside the closure, which is pressed against the mouth edges of the pouring openings when the closure is screwed on. Unfortunately, the sealing of the pouring openings via the sealing membrane is often insufficient. When screwing in and unscrewing the screw cap, the opening edges rub against the sealing surface of the sealing membrane. This can lead to wear of the sealing membrane, which then no longer closes properly. The child safety of this known rotary closure consists in a positive locking of locking elements arranged on the closure with correspondingly formed counterparts on the bottle neck. This requires that bottles that are to be equipped with a child-resistant closure, must be made separately. For reasons of production technology and to keep the costs down, it would be desirable if the same multi-chamber bottle could be used on the one hand for filling problem-free contents and on the other hand also for those ingredients which require a child-resistant closure.
Aufgabe der vorliegenden Erfindung ist es daher, die Nachteile von Sicherheitsdrehverschlüssen für Mehrkammerflaschen, insbesondere von Zweikarmmerflaschen, zu beseitigen. Es soll ein Sicherheitsdrehverschluss geschaffen werden, der auch nach mehrmaligem Öffnen und Schliessen die Ausgiessöffnungen zuverlässig verschliesst. Die Handhabung des Sicherheitsdrehverschlusses soll trotzdem einfach und selbsterklärend sein. Dabei soll der Verschluss einen einfachen Aufbau aufweisen und kostengünstig in der Herstellung sein. Die Notwendigkeit, für die Anwendung des Sicherheitsdrehverschlusses eine gesonderte Flaschenserie herzustellen, soll entfallen.The object of the present invention is therefore to eliminate the disadvantages of safety turning closures for multi-chamber bottles, in particular of two-arm bottles. It is to be created a security turning lock, which also after repeated opening and closing closes the pouring openings reliably. The handling of the safety rotary closure should still be simple and self-explanatory. The closure should have a simple structure and be inexpensive to manufacture. The need to produce a separate series of bottles for the application of the safety rotary closure should be omitted.
Die Lösung dieser Aufgaben besteht in einem Sicherheitsdrehverschluss für eine Mehrkammerflasche, insbesondere für eine Zweikammerflasche mit separaten Ausgiessstutzen, welche die im kennzeichnenden Abschnitt des Patentanspruchs 1 aufgelisteten Merkmale aufweist. Weiterbildungen und/oder vorteilhafte Ausführungsvarianten der Erfindung sind Gegenstand der abhängigen Patentansprüche.The solution to these problems consists in a safety rotary closure for a multi-chamber bottle, in particular for a two-chamber bottle with separate Ausgiessstutzen which has the features listed in the characterizing portion of
Durch die Erfindung wird ein Sicherheitsdrehverschluss für eine Mehrkammerflasche, insbesondere für eine Zweikammerflasche, vorgeschlagen, die für jede Kammer einen separaten Ausgiessstutzen mit einer Ausgiessöffnung besitzt und einen Drehverschluss aufweist, der auf ein gemeinsames Halsteil der Mehrkammerflasche aufschraubbar ist. Der Sicherheitsdrehverschluss ist mit einer mechanisch wirkenden Kindersicherungseinrichtung gegen ein unbefugtes Lösen des Verschlusses ausgestattet und weist im wesentlichen konische Dichtungsteile auf, die im aufgeschraubten Zustand in die Ausgiessöffnungen der Ausgiessstutzen eingreifen und mit den Innenwandungen der Ausgiessstutzen dichtend zusammenwirken. Sämtliche Verriegelungselemente der Kindersicherungseinrichtung sind am Sicherheitsdrehverschluss angeordnet.The invention proposes a safety rotary closure for a multi-chamber bottle, in particular for a two-chamber bottle, which has a separate pour spout for each chamber with a pouring opening and has a rotary closure which can be screwed onto a common neck portion of the multi-chamber bottle. The safety rotary closure is equipped with a mechanically acting child safety device against unauthorized release of the closure and has substantially conical sealing parts which engage in the spouted openings in the Ausgiessstutzen and sealingly cooperate with the inner walls of the Ausgiessstutzen. All locking elements of the child safety device are arranged on the safety rotary closure.
Durch das Vorsehen von konischen Dichtungsteilen ist das Problem einer abrasiven Abnutzung von Dichtmembranen oder dergleichen scheibenartigen Dichtungselementen beseitigt. Die konischen Dichtungsteile gleiten axial in die Ausgiessöffnungen und werden durch den Schliessdruck gegen die Innenwandungen der Ausgiessstutzen gepresst. Beim Lösen des Verschlusses gleiten die konischen Dichtungsteile wieder axial aus den Ausgiessöffnungen heraus. Die Gefahr einer abrasiven Abnutzung der Dichtflächen and den Öffnungsrändern ist beseitigt. Indem sämtliche Verriegelungselemente der Kindersicherungseinrichtung am Sicherheitsdrehverschluss angeordnet sind, entfällt die Notwendigkeit einer gesonderten Flaschenproduktion mit am Flaschenhals angeordneten Verriegelungselementen. Ob die Flasche mit einem Sicherheitsdrehverschluss ausgestattet werden muss, entscheidet sich erst anhand der abzufüllenden Komponenten. Die Produktion des Typs der Mehrkammerflasche ist davon weitgehend unabhängig. Dies führt bei den Flaschenproduzenten zu einer Verringerung der erforderlichen Formwerkzeuge. Die Stückzahlen der betroffenen Mehrkammerflaschen können deutlich erhöht werden, was sich sehr vorteilhaft auf die Wirtschaftlichkeit der Produktion auswirkt.By providing conical sealing parts, the problem of abrasive wear of sealing membranes or similar disc-like sealing elements is eliminated. The conical sealing parts slide axially into the pouring openings and are pressed by the closing pressure against the inner walls of the pouring spouts. Upon release of the closure, the conical seal parts slide axially out of the pouring out. The risk of abrasive wear of the sealing surfaces and the opening edges is eliminated. By arranging all locking elements of the child-safety device on the safety rotary closure, eliminates the need for a separate production bottles with arranged on the bottle neck locking elements. Whether the bottle has to be equipped with a safety turning cap is decided on the basis of the components to be filled. The production of the type of multi-chamber bottle is largely independent of this. This leads to a reduction in the necessary molds for the bottle producers. The quantities of the affected multi-chamber bottles can be significantly increased, which has a very beneficial effect on the economics of production.
Die Kombination eines Sicherheitsdrehverschlusses mit konischen Dichtungsteilen ist in einer zweckmässigen Ausführungsvariante der Erfindung durch einen zweiteiligen Aufbau realisiert. Dabei setzt sich der Sicherheitsdrehverschluss aus einem Überdeckel und einem Dichteinsatz zusammen. Der Überdeckel weist eine Deckfläche und eine davon abragende Zylinderwandung aufweist, deren Innenfläche bereichsweise mit Gewindeabschnitten versehen ist. Der Dichteinsatz ist drehbar und axial verschiebbar im Überdeckel gehalten. Die konischen Dichtungsteile ragen von der Deckfläche des Überdeckels abgewandten Unterseite des Dichteinsatzes ab. Der separate Dichteinsatz erhöht die Flexibilität des Sicherheitsdrehverschlusses. Insbesondere besteht die Möglichkeit je nach Art der Inhaltsstoffe der Mehrkammerflasche Dichteinsätze aus unterschiedlichen Materialien in den Überdeckel einzusetzen. Auch können je nach Grösse der Austrittsöffnung Dichteinsätze mit unterschiedlich dimensionierten Dichtungsteilen in den Überdeckel eingesetzt werden. Der Überdeckel kann beispielsweise als ein Normteil gefertigt sein, das auf eine Mehrkammerflasche mit entsprechend vereinheitlichtem Durchmesser des gemeinsamen Halsteils aufschraubbar ist. Je nachdem, ob es sich bei der Mehrkammerflasche dann um eine Zwei- oder beispielsweise eine Dreikammerflasche handelt, kann ein entsprechender Dichteinsatz mit zwei oder drei von der Unterseite abragenden Dichtungsteilen in den Überdeckel eingesetzt werden. Dadurch können die Überdeckel in einer viel grösseren Stückzahl hergestellt werden, was auch die Wirtschaftlichkeit der Deckelproduktion deutlich erhöht.The combination of a safety rotary closure with conical sealing parts is realized in a suitable embodiment of the invention by a two-part construction. The safety turning cap consists of an overcap and a sealing insert. The overcap has a top surface and a cylinder wall projecting therefrom, the inner surface of which is provided in regions with threaded portions. The sealing insert is rotatably and axially displaceably held in the cover. The conical sealing parts protrude from the top surface of the overcap facing away bottom of the sealing insert. The separate sealing insert increases the flexibility of the safety turning cap. In particular, it is possible, depending on the nature of the ingredients of the multi-chamber bottle sealing inserts made of different materials in the cover to use. Also, depending on the size of the outlet opening sealing inserts can be used with differently sized sealing parts in the cover. The overcap may for example be made as a standard part, which can be screwed onto a multi-chamber bottle with a correspondingly uniform diameter of the common neck part. Depending on whether the multi-chamber bottle is then a two- or, for example, a three-chamber bottle, a corresponding sealing insert with two or three sealing parts projecting from the underside can be inserted into the overcap. As a result, the overcap can be produced in a much larger number, which also significantly increases the economy of the lid production.
Eine Variante des Sicherheitsdrehverschlusses sieht vor, dass die Sicherungsteile von zwei Vorsprüngen am Überdeckel und zwei korrespondierenden Sperrnocken am Dichteinsatz gebildet sind. Die zwei Vorsprünge ragen von einander gegenüberliegenden Abschnitten der Innenfläche der Zylinderwandung ab und sind hakenartig in Richtung der Deckfläche des Überdeckels gekrümmt. Sie sind in einem axialen Abstand von der Deckfläche angeordnet, der grösser ist als eine axiale Höhe des Dichteinsatzes. Die zwei hakenartigen Vorsprünge stützen den Dichteinsatz einerseits axial ab und wirken andererseits mit den korrespondierenden Sperrnocken zusammen, die von der Unterseite des Dichteinsatzes abragen. Bei der Montage wird der Dichteinsatz einfach in den Überdeckel eingedrückt. Dabei gleitet er hinter die hakenartigen Vorsprünge, welche verhindern, dass er wieder aus dem Überdeckel fällt. Der Dichteinsatz liegt axial und radial frei beweglich im Überdeckel. Beim Zuschrauben des Sicherungsdrehverschlusses wird der Dichteinsatz mitgedreht, bis seine konischen Dichtungsteile in die Ausgiessöffnungen gleiten. Dadurch ist ein weiteres Mitdrehen des Dichteinsatzes verhindert. Beim weiteren Zuschrauben verdreht sich der Überdeckel gegenüber dem Dichteinsatz und wird auch axial gegenüber diesem in Richtung Flasche bewegt. Schliesslich liegt die Deckfläche des Überdeckels am Dichtteil an und presst die konischen Dichtungsteile weiter in die Ausgiessöffnungen hinein.A variant of the safety turning closure provides that the securing parts of two projections on the cover and two corresponding locking cam on Seal insert are formed. The two projections protrude from opposite portions of the inner surface of the cylinder wall and are hook-like curved in the direction of the top surface of the cover. They are arranged at an axial distance from the top surface, which is greater than an axial height of the sealing insert. The two hook-like projections support the sealing insert on the one hand axially and on the other hand cooperate with the corresponding locking cam, which protrude from the underside of the sealing insert. During assembly, the sealing insert is simply pressed into the cover. He slides behind the hook-like projections, which prevent him from falling out of the cover again. The sealing insert is axially and radially freely movable in the cover. When screwing in the turn-lock cap, the sealing insert is turned along until its conical sealing parts slide into the pouring openings. As a result, further co-rotation of the sealing insert is prevented. Upon further screwing the cover over the sealing insert is rotated and is also moved axially relative to this in the direction of the bottle. Finally, the top surface of the cover abuts the sealing part and presses the conical sealing parts further into the pouring openings.
Die Sperrnocken sind in Umfangsrichtung mit Vorteil keilförmig ausgebildet. Die keilförmigen Sperrnocken erleichtern beim Zuschrauben des Sicherheitsdrehverschlusses die relative Verdrehbarkeit des Überdeckels und des Dichteinsatzes. In Öffnungsrichtung sperren die zusammenwirkenden Sperrnocken und die hakenartigen Vorsprünge und verhindern eine relative Verdrehung des Deckelteils gegenüber dem Dichteinsatz. Die Verriegelung des Sicherheitsdrehverschlusses gegen ein Öffnen ergibt sich aus der Verhinderung der relativen Verdrehung des Deckelteils gegenüber dem Dichteinsatz und der sperrenden Wirkung der in die Ausgiessöffnung ragenden konischen Dichtungsteile.The locking cams are wedge-shaped in the circumferential direction with advantage. The wedge-shaped locking cams facilitate the relative rotatability of the cover and the sealing insert when the safety turning lock is screwed on. In the opening direction, the cooperating locking cam and the hook-like projections lock and prevent relative rotation of the lid member relative to the sealing insert. The locking of the safety rotary closure against opening results from the prevention of the relative rotation of the cover part relative to the sealing insert and the blocking effect of the conical sealing parts projecting into the pouring opening.
Zum Öffnen des Sicherheitsdrehverschlusses muss die Drehverriegelung der zusammenwirkenden Vorsprünge und Sperrnocken aufgehoben werden. Dies kann auf unterschiedliche Weise erfolgen. Eine vorteilhafte Ausführungsvariante des Sicherheitsdrehverschlusses sieht dazu vor, dass die Vorsprünge an den Innenflächen von einander gegenüberliegend angeordneten Lappenabschnitten des Überdeckels angeordnet sind. Die in der Zylinderwandung des Überdeckels vorgesehenen Lappenabschnitte sind durch Druck radial elastisch verstellbar. Durch das Zusammenpressen der Lappenabschnitte werden die Vorsprünge nach innen bewegt und die Sperrnocken können durch den Zwischenraum zwischen der Zylinderwandung und den hakenartig gekrümmten Vorsprüngen gleiten. Dadurch ist die Drehverriegelung aufgehoben und der Überdeckel kann relativ zum Dichteinsatz verdreht werden. Sobald der Dichteinsatz auf den Vorsprüngen des Überdeckels aufliegt wird er beim weiteren Aufschrauben des Deckels von den Ausgiessöffnungen abgehoben. Sobald die konischen Dichtungsteile aus den Ausgiessöffnungen herausgleiten kann der Dichteinsatz wieder mit dem Überdeckel mitdrehen. Ein weiteres Zusammenpressen der Lappenabschnitte ist dann nicht mehr erforderlich.To open the safety twist lock, the twist lock of the co-operating projections and locking cams must be removed. This can be done in different ways. An advantageous embodiment of the safety turning closure provides that the projections on the inner surfaces of oppositely arranged flap portions of the cover arranged are. The tab portions provided in the cylinder wall of the cover are radially elastically adjustable by pressure. By compressing the flap portions, the projections are moved inwardly and the locking cams can slide through the gap between the cylinder wall and the hook-like curved projections. As a result, the rotation lock is released and the lid can be rotated relative to the sealing insert. As soon as the sealing insert rests on the projections of the overcap, it is lifted off the pouring openings when the lid is screwed on further. As soon as the conical sealing parts slide out of the pouring openings, the sealing insert can turn again with the overcap. Further compression of the flap sections is then no longer necessary.
Um dem erwachsenen Anwender die Funktion des Sicherheitsdrehverschlusses noch besser zu verdeutlichen und um einen besseren Angriff der Finger am Überdeckel zu gewährleisten, sind die Lappenabschnitte mit Vorteil an ihren Aussenflächen wenigstens bereichsweise mit einer Riffelung versehen.In order to better illustrate the function of the safety rotary closure for the adult user and to ensure a better attack of the fingers on the overcap, the flap sections are advantageously provided on their outer surfaces at least partially with a corrugation.
Um das Aufsetzen des Sicherheitsdrehverschlusses auf die Mehrkammerflasche zu erleichtern, ragt in einer zweckmässigen Ausführungsvariante des Sicherheitsdrehverschluss von der Unterseite des Dichteinsatzes ein mittig angeordneter Zentrierzapfen ab. Bei angesetztem Deckel ragt der Zentrierzapfen in die Aussparung zwischen den Ausgiessstutzen der Flasche und erleichtert die Positionierung. Während des Zuschraubens des Sicherheitsdrehverschlusses gleitet der Zentrierzapfen in die Aussparung zwischen den Ausgiessstutzen.In order to facilitate the placement of the safety rotary closure on the multi-chamber bottle, protrudes in a convenient embodiment of the safety rotary closure from the bottom of the sealing insert from a centrally located centering pin. With the lid attached, the centering pin protrudes into the recess between the spout of the bottle and facilitates positioning. During the screwing of the safety turning cap, the centering pin slides into the recess between the pouring spouts.
In einer weiteren zweckmässigen Ausführungsvariante ist der Zentrierzapfen hohl und zur Aufnahme eines von der Deckfläche des Überdeckels abragenden Führungsstiftes ausgebildet. Der Führungsstift verbessert die freie Lage des Dichteinsatzes im Überdeckel noch weiter und verhindert ein allfälliges Kippen des Dichteinsatzes.In a further expedient embodiment, the centering pin is hollow and designed to receive a projecting from the top surface of the overcap guide pin. The guide pin further improves the free position of the sealing insert in the cover and prevents any tilting of the sealing insert.
Ein weiteres Ausführungsbeispiel des Sicherheitsdrehverschlusses, das ebenfalls aus nur zwei Teilen besteht, die einfach miteinander montierbar sind, umfasst einen Überdeckel, der eine Deckfläche und eine davon abragende Zylinderwandung aufweist, deren Innenfläche bereichsweise mit Gewindeabschnitten versehen ist, und einen drehbar im Überdeckel gehaltenen, im wesentlichen hutartig ausgebildeten Dichteinsatz. Von der Deckfläche des Überdeckels abgewandten Unterseite des hutartigen Dichteinsatzes ragen die konischen Dichtungsteile ab. Der hutartige Dichteinsatz weist einen krempenartigen Randabschnitt auf, an dem wenigstens eine Sperrnocke ausgebildet ist, die mit wenigstens einem korrespondierenden Sperrorgan des Überdeckels zusammenwirkt.Another embodiment of the safety turning closure, which also consists of only two parts which are easy to assemble with each other, comprises an overcap, which has a top surface and a cylinder wall projecting therefrom, the inner surface of which is provided in regions with threaded portions, and a sealing insert which is rotatably held in the overcap, essentially a hat-shaped design. From the top surface of the overcap facing away underside of the hat-shaped sealing insert protrude the conical seal parts. The hat-shaped sealing insert has a brim-like edge portion on which at least one locking cam is formed, which cooperates with at least one corresponding locking member of the cover.
Jeder Sperrnocken ist in Schliessdrehrichtung keilförmig ausgebildet. Dies Erleichtert bei der relativen Verdrehung des Überdeckels und des Dichteinsatzes in Schliessdrehrichtung ein Übergleiten der Sperrorgane des Überdeckels über die Sperrnocken. In die entgegengesetzte relative Drehrichtung weist jeder Sperrnocken eine Sperrfläche auf, die ein Widerlager für das Sperrorgan des Überdeckels bildet.Each locking cam is wedge-shaped in the closed direction of rotation. This facilitates the relative rotation of the cover and the sealing insert in the closed direction of rotation over sliding of the locking members of the cover over the locking cams. In the opposite relative direction of rotation, each locking cam on a locking surface, which forms an abutment for the locking member of the cover.
Zur Erhöhung der Sicherheitsfunktion des Sicherheitsdrehverschlusses und zur Verbesserung der Handhabung erweist es sich von Vorteil, wenn zwei Sperrnocken vorgesehen sind, die einander etwa diagonal gegenüberliegend am Randabschnitt des Dichteinsatzes ausgebildet sind und mit einer entsprechenden Anzahl von Sperrorganen am Überdeckel zusammenwirken. Die korrespondierenden Sperrorgane am Überdeckel sind dabei von Lappenabschnitten gebildet, die einstückig am Überdeckel ausgebildet sind und durch Druck radial elastisch verstellbar sind.To increase the safety function of the safety rotary closure and to improve handling, it proves advantageous if two locking cams are provided, which are formed approximately diagonally opposite each other at the edge portion of the sealing insert and cooperate with a corresponding number of locking members on the cover. The corresponding locking members on the cover are formed by flap portions which are integrally formed on the cover and are radially elastically adjustable by pressure.
Zur Erleichterung der Handhabbarkeit sind die Lappenabschnitte an ihrer Aussenseite wenigstens bereichsweise mit einer Riffelung versehen.To facilitate handling, the tab portions are provided on their outer side at least partially with a corrugation.
Als einfache Sicherung gegen ein Herausfallen des Dichteinsatzes aus dem Überdeckel stützt sich der Dichteinsatz im Überdeckel an einem oder mehreren Vorsprüngen ab, die aus der Innenfläche der Zylinderwandung des Überdeckels vorspringen und einen geringeren Abstand von der Deckfläche aufweist bzw. aufweisen als die Gewindeabschnitte. Der bzw. die Vorsprünge sind sehr einfach integral mit dem Überdeckel herstellbar. Bei der Montage wird der Dichteinsatz einfach in den Überdeckel hineingedrückt, bis er über den bzw. die Vorsprünge gleitet und sich axial daran abstützt.As a simple safeguard against falling out of the sealing insert from the cover, the sealing insert in the cover is supported on one or more projections which project from the inner surface of the cylinder wall of the cover and has a smaller distance from the top surface or have as the threaded portions. The projection or projections are very easy to produce integrally with the cover. During assembly, the sealing insert is simply pressed into the overcap until it slides over the projection (s) and is axially supported thereon.
In einer weiteren zweckmässigen Variante der Erfindung, die im Nachstehenden noch zu erläuternde Weiterbildungen ermöglicht, ist der Dichteinsatz axial unverschiebbar im Überdeckel gehalten. Dies kann beispielsweise durch ein axiales Einspannen des Dichteinsatzes zwischen axial beabstandeten Vorsprüngen im Überdeckel erfolgen. Vorzugsweise weist dazu jedoch der hutartig ausgebildete Dichteinsatz eine Höhe auf, die im wesentlichen dem Abstand des bzw. der Vorsprünge von der Deckfläche des Überdeckels entspricht. Nach seiner Montage stösst der Dichteinsatz gegen die Deckfläche des Überdeckels und ist dadurch axial nicht mehr verschiebbar.In a further expedient variant of the invention, which allows further developments to be explained below, the sealing insert is held axially immovably in the overcap. This can be done for example by an axial clamping of the sealing insert between axially spaced projections in the cover. Preferably, however, has the hat-like sealing insert to a height that corresponds to the distance of the or the projections of the top surface of the cover substantially. After its installation, the sealing insert abuts against the top surface of the cover and is therefore no longer axially displaceable.
Die axiale Unverschiebbarkeit des Dichteinsatzes erlaubt es, eine sehr einfache Ausführungsvariante einer Überdrehsicherung vorzusehen. Die Überdrehsicherung ist dabei von wenigstens einem, am krempenartigen Randabschnitt des Dichteinsatzes ausgebildeten Flügelabschnitt gebildet. Von der Unterseite des Flügelabschnitts ragt ein Fortsatz derart axial ab, dass der Flügelabschnitt beim Aufschrauben des Sicherheitsdrehverschlusses auf die Mehrkammerflasche axial elastisch verschiebbar ist und ein Widerlager für das am Überdeckel ausgebildete Sperrorgan, insbesondere den Lappenabschnitt bildet. Sobald der Lappenabschnitt gegen den in die Höhe gedrückten Flügelabschnitt stösst, ist eine weiter relative Verdrehung des Überdeckels gegenüber dem Dichteinsatz verhindert. Dadurch kann der Sicherheitsdrehverschluss nicht mehr überdreht werden.The axial inability to move the sealing insert allows to provide a very simple embodiment of an over-rotation. The over-rotation lock is formed by at least one, formed on the brim-like edge portion of the sealing insert wing portion. From the underside of the wing section, an extension projects axially such that the wing section is axially elastically displaceable when the safety rotary lock is screwed onto the multichamber bottle and forms an abutment for the blocking element, in particular the flap section, formed on the cover. As soon as the flap section abuts against the wing section which is pressed up, a further relative rotation of the cover over the sealing insert is prevented. As a result, the safety twist lock can not be over-tightened.
Der Flügelabschnitt ist in Schliessdrehrichtung nach dem Sperrnocken angeordnet und weist vom Sperrnocken einen Abstand auf, der grösser ist als eine in Umfangsrichtung gemessene Breite des Sperrorgans, insbesondere des Lappenabschnitts am Überdeckel. Beim Überfahren des Sperrnockens klappt der Lappenabschnitt elastisch in seine Ausgangsstellung zurück und gelangt in den Raum zwischen dem Sprerrnocken und dem hochgedrückten Flügelabschnitt. Dadurch ist eine weitere Relativverdrehung des Überdeckels zum Dichteinsatz in die Schliessdrehrichtung ebenso behindert wie in die entgegengesetzte Öffnungsdrehrichtung. Der Endpunkt des Aufdrehens des Sicherheitsdrehverschlusses ist durch die Anordnung des hochstellbaren Flügelabschnitts vorgegeben. Dadurch kann der Sicherheitsdrehverschluss nicht mehr überdreht werden. Zum Öffnen des Sicherheitsdrehverschlusses muss der Lappenabschnitt nach innen gepresst werden, bis sein freies Ende weiter ins Innere des Überdeckels ragt als der Sperrnocken. Erst in dieser Stellung ist eine Relativdrehung zwischen dem Überdeckel und dem Dichteinsatz und damit ein Abschrauben des Sicherheitsdrehverschlusses ermöglicht.The wing portion is arranged in the closing direction of rotation after the locking cam and has the locking cam on a distance which is greater than a measured width in the circumferential direction of the locking member, in particular of the tab portion on the cover. When driving over the locking cam of the flap portion elastically folds back into its original position and enters the space between the Sprerrnocken and the high-pressed wing section. As a result, a further relative rotation of the cover to the sealing insert in the closed direction of rotation is hindered as well as in the opposite direction of open rotation. The end point of unscrewing the safety turn-lock is predetermined by the arrangement of the liftable wing section. As a result, the safety twist lock can not be over-tightened. To open the safety twist lock, the flap section must be pressed inwards until its free end protrudes further into the interior of the cover than the locking cam. Only in this position, a relative rotation between the cover and the sealing insert and thus unscrewing the safety rotary closure is possible.
Vorzugsweise sind in Entsprechung zu der Anordnung von zwei Lappenabschnitten und Sperrnocken auch zwei Flügelabschnitte vorgesehen, die einander am Randabschnitt des Dichteinsatzes etwa diametral gegenüberliegen. Dadurch ist die Überdrehsicherheit weiter verbessert, und die Handhabung des Sicherheitsdrehverschlusses ist aus Symmetriegründen erleichtert.Preferably, in correspondence with the arrangement of two flap sections and locking cams, two wing sections are also provided, which lie approximately diametrically opposite one another at the edge section of the sealing insert. As a result, the over-rotation safety is further improved, and the handling of the safety rotary closure is facilitated for reasons of symmetry.
Besonders einfach herstellbar ist ein Flügelabschnitt indem in den krempenartigen Randabschnitt ein radial und ein in Umfangsrichtung verlaufender Einschnitt gemacht wird. Der dadurch gebildete Flügelabschnitt ist gelenkig mit dem Randabschnitt verbunden.It is particularly easy to produce a wing section by making a radially and circumferentially extending cut in the brim-like edge section. The wing portion formed thereby is hingedly connected to the edge portion.
Der erfindungsgemässe Sicherheitsdrehverschluss ist für Mehrkammerflaschen mit zwei oder mehreren Kammern mit separaten Ausgiessstutzen und Ausgiessöffnungen ausgebildet. In seiner am häufigsten benötigten Variante ist der Sicherheitsdrehverschluss für Zweikammerflaschen ausgebildet und weist er zwei einander gegenüberliegende konische Dichtungsteile auf. Bei den üblichen Deckelgrössen, die noch bequem greifbar und betätigbar sind, finden zwei konische Dichtungsteile ausreichenden Platz. Die Grösse der Dichtungsteile ist dabei auf die herkömmlichen Dimensionierungen der Ausgiessöffnungen von Zweikammerflaschen abgestimmt. Es entfällt die Notwendigkeit einer separaten Flaschenproduktion, die auf den gewählten Sicherheitsdrehverschluss abgestimmt ist. Für eine kostengünstige, massentechnische Herstellung des Sicherheitsdrehverschlusses sind der Überdeckel und der Dichteinsatz in einem Kunststoffspritzverfahren hergestellt.The inventive safety twist lock is designed for multi-chamber bottles with two or more chambers with separate pour spouts and pouring openings. In its most commonly required variant of the safety rotary closure for two-chambered bottles is formed and it has two opposing conical sealing parts. In the usual lid sizes, which are still easy to reach and operate, find two conical sealing parts sufficient space. The size of the sealing parts is matched to the conventional dimensions of the pouring of two-chamber bottles. It eliminates the need for a separate bottle production, which is tuned to the selected safety turning cap. For a cost-effective, mass-technical production of the safety turning closure, the overcap and the sealing insert are produced in a plastic injection molding process.

Der Sicherheitsdrehverschluss 1 weist einen Überdeckel 11 und einen Dichteinsatz 12 auf. Von einer Deckfläche 13 des Überdeckels 11 ragt eine Zylinderwandung 14 ab, die in ihrem axialen Endbereich mit einem Innengewinde 16 versehen ist. Das Innengewinde 16 des Überdeckels 11 und das Aussengewinde 6 am gemeinsamen Flaschenhals 5 sind aufeinander abgestimmt. An zwei einander gegenüberliegenden Abschnitten der Zylinderwandung 14 ragen Vorsprünge 15 ab, die hakenartig gekrümmt sind und sich in Richtung der Deckfläche 13 erstrecken. Der axiale Abstand zwischen den freien Enden der hakenartig gekrümmten Vorsprünge 15 und der Deckfläche 13 ist etwas grösser als die axiale Höhe des Dichteinsatzes 12. Die Vorsprünge 15 sind an Lappenabschnitten 18 angeordnet, die jeweils durch zwei axiale und einen radialen Einschnitt in der Zylinderwandung 14 bzw. der Deckfläche 13 des Überdeckels 11 geschaffen sind. Die Lappenabschnitte 18 sind radial elastisch federbar ausgebildet. An ihrer Aussenseite sind die Lappenabschnitte 18 wenigstens bereichsweise mit einer Riffelung versehen.The
