Description

Die Erfindung betrifft einen Dosenverschluss, insbesondere für eine Milchdose, gemäß dem Oberbegriff des Anspruchs 1, sowie eine Dose gemäß Anspruch 12 mit einem derartigen Dosenverschluss.The invention relates to a can closure, in particular for a milk can, according to the preamble of claim 1, and a can according to claim 12 with such a can closure.

Herkömmliche Kondensmilchdosen werden üblicherweise geöffnet, indem in den Dosendeckel randnah eine Ausgießöffnung und auf der gegenüberliegenden Seite eine Belüftungsöffnung eingestochen wird.Conventional condensed milk cans are usually opened by a pouring opening into the can lid and a ventilation opening on the opposite side is pierced.

Problematisch an derartigen bekannten Kondensmilchdosen ist der neben der Ausgießöffnung am Dosenrand hervorstehende Dosenfalz, der ein sauberes Ausgießen der Kondensmilch behindert und dadurch die gewünschte Dosierung der Kondensmilch erschwert. Darüber hinaus können sich am Dosenrand Kondensmilchreste ansammeln, was unhygienisch ist und den optischen Eindruck der Kondensmilchdose beeinträchtigt. Schließlich kann sich bei den bekannten Kondensmilchdosen die Ausgießöffnung oder die Belüftungsöffnung mit Kondensmilchresten zusetzen, was eine erneute Öffnung erforderlich macht.The problem with such known Kondensmilchdosen the next to the pouring opening at the edge of the can projecting can fold, which impedes a clean pouring of the condensed milk and thereby complicates the desired dosage of the condensed milk. In addition, condensed milk residues can accumulate on the edge of the can, which is unhygienic and adversely affects the visual impression of the condensed milk can. Finally, in the known condensed milk cans, the pouring opening or the ventilation opening can become clogged with condensed milk residues, which necessitates a reopening.

Weiterhin sind beispielsweise für Bier oder koffeinhaltige Limonaden Getränkedosen bekannt, die einen Aufreiß- oder Eindrückverschluss aufweisen. Hierbei ist in dem Dosendeckel ein meist dreieckiges Wandungsteil vorgesehen, das von dem übrigem Dosendeckel durch eine Schwächungslinie abgegrenzt ist und mittels einer Lasche ausgerissen oder in die Getränkedose hineingedrückt werden kann, um eine Ausgießöffnung in dem Dosendeckel freizugeben. Derartige Eindrück- oder Aufreißverschlüsse werden jedoch bei Kondensmilchdosen nicht eingesetzt, da die entstehenden Ausgießöffnungen in der Regel zu groß wären. Darüber hinaus würde der am Dosenrand hervorstehende Dosenfalz auch bei einem derartigen Eindrück- oder Aufreißverschluss zu den eingangs beschriebenen Problemen führen.Furthermore, for example, for beer or caffeinated sodas beverage cans are known which have a tear or Eindrückverschluss. Here, a mostly triangular wall part is provided in the can lid, which is delimited from the rest of the can lid by a line of weakness and can be torn by a tab or pressed into the beverage can to release a pouring opening in the can lid. However, such Eindrück- or Aufreißverschlüsse are not used in condensed milk cans, since the resulting pouring openings would usually be too large. In addition, would lead the can rabble projecting at the edge of the can even with such a push-in or zipper to the problems described above.

Weitere Verschlüsse sind aus US 2 885 084, EP 0 577 865, US 5 495 706, EP 1 038 784, DE 100 17 467, EP 0 760 339 und DE 94 20 437.3 bekannt.Further closures are known from US Pat. No. 2,885,084, EP 0 577 865, US Pat. No. 5,495,706, EP 1 038 784, DE 100 17 467, EP 0 760 339 and DE 94 20 437.3.

Der Erfindung liegt deshalb die Aufgabe zugrunde, einen Dosenverschluss zu schaffen, der bei einer Kondensmilchdose ein sauberes Ausgießen von Kondensmilch ermöglicht und eine Verschmutzung durch anhaftende Kondensmilchreste verhindert.The invention is therefore an object of the invention to provide a can closure, which allows for a condensed milk can clean pouring of condensed milk and prevents contamination by adhering Kondensmilchreste.

Die Aufgabe wird durch einen Dosenverschluss gemäß Anspruch 1 beziehungsweise eine entsprechende Dose gemäß Anspruch 12 gelöst.The object is achieved by a can closure according to claim 1 or a corresponding box according to claim 12.

Die Erfindung umfasst die allgemeine technische Lehre, einen Dosenverschluss zu schaffen, der mindestens teilweise aus Kunststoff besteht und eine Ausgießöffnung aufweist, die von einem Benutzer ohne Werkzeug manuell geöffnet werden kann, wobei die Ausgießöffnung vorzugsweise zu dem Dosendeckel beabstandet ist.The invention comprises the general technical teaching of providing a can closure which is at least partially made of plastic and has a pouring opening which can be opened manually by a user without tools, the pouring opening being preferably spaced from the can lid.

Die zu dem Dosendeckel beabstandete Anordnung der Ausgießöffnung bietet den Vorteil, dass ein sauberes Ausgießen möglich ist und eine Verschmutzung des Dosendeckels durch Reste der ausgeschütteten Flüssigkeit verhindert wird.The spaced apart from the can lid arrangement of the pouring opening has the advantage that a clean pouring is possible and contamination of the can lid is prevented by residues of the spilled liquid.

Die Fertigung des erfindungsgemäßen Dosenverschlusses aus Kunststoff bietet dagegen den Vorteil, dass dieser in einen Ausschnitt in dem Dosendeckel eingesetzt werden kann und den Ausschnitt dabei abdichtet.The production of plastic can closure according to the invention, on the other hand, offers the advantage that it can be inserted into a cutout in the can lid and thereby seals the cutout.

Bei einer Fertigung des Dosenverschlusses aus Kunststoff besteht das Dosenunterteil vorzugsweise aus zwei Komponenten, die unterschiedlich hart sind. Die weichere Komponente des Dosenunterteils dient hierbei als Dichtung und liegt im montierten Zustand am Rand des Ausschnitts in dem Dosendeckel an.In a production of the can closure made of plastic, the lower part of the can is preferably made of two components that are different hardness. The softer component of the can bottom serves as a seal and rests in the assembled state on the edge of the cutout in the can lid.

Vorzugsweise liegt die Dichtung hierbei nicht nur auf dem Rand des in dem Dosendeckel angeordneten Ausschnitts auf, sondern umschließt den Rand des Ausschnitts, wodurch der Rand des Ausschnitts vor Korrosion geschützt wird. In diesem Zusammenhang ist zu erwähnen, dass das Dosenblech vor der Verarbeitung üblicherweise mit einer Schutzlackschicht überzogen wird. Beim Ausstanzen des Ausschnitts in dem Dosendeckel wird diese Schutzlackschicht jedoch am Rand des Ausschnitts beschädigt, was dort zu Korrosion führen kann. In dieser Variante der Erfindung wird also vorteilhaft eine Korrosion am Rand des Ausschnitts im Dosendeckel verhindert, indem die Schnittkante von der Dichtung des erfindungsgemäßen Dosenverschlusses umschlossen wird.Preferably, the seal is not only on the edge of the arranged in the can lid cutout, but enclosing the edge of the cutout, whereby the edge of the cutout is protected from corrosion. In this context, it should be mentioned that the can sheet is usually coated with a protective lacquer before processing. When punching the cutout in the can lid, however, this protective lacquer layer is damaged at the edge of the cutout, which can lead to corrosion there. In this variant of the invention, therefore, a corrosion at the edge of the cutout in the can lid is advantageously prevented by the cut edge is enclosed by the seal of the can closure according to the invention.

Als Material für den erfindungsgemäßen Dosenverschluss eignen sich besonders vorteilhaft Polyethylen (PE) und Polypropylen (PP), jedoch ist die Erfindung hinsichtlich des Materials für den Dosenverschluss nicht auf diese Kunststoffe beschränkt, sondern auch mit anderen Kunststoffen realisierbar.Polyethylene (PE) and polypropylene (PP) are particularly advantageous as material for the can closure according to the invention, but the invention is not limited to these plastics in terms of the material for the can closure but can also be realized with other plastics.

Erfindungsgemäß weist der Dosenverschluss ein Verschlussunterteil und einen Verschlussdeckel auf, wobei das Verschlussunterteil in einen Ausschnitt in dem Dosendeckel einsetzbar ist und mit dem Dosendeckel formschlüssig verbunden werden kann, während der Verschlussdeckel durch ein Gelenk mit dem Verschlussunterteil verbunden ist und von einer Transportstellung in eine Gebrauchsstellung schwenkbar ist. Hierbei ist in dem Verschlussunterteil eine Ausgießöffnung angeordnet und der Verschlussdeckel weist Mittel auf, um die Ausgießöffnung in der Gebrauchsstellung des Verschlussdeckels zu öffnen. Der Verschlussdeckel wird hierbei also zum Öffnen des Dosenverschlusses vorzugsweise auf das Verschlussunterteil geklappt, wobei die in dem Verschlussunterteil angeordnete Ausgießöffnung automatisch geöffnet wird.According to the invention, the can closure has a closure bottom part and a closure lid, wherein the closure bottom part can be inserted into a cutout in the can lid and can be positively connected to the can lid, while the closure lid is connected to the closure bottom part by a hinge and can be swiveled from a transport position into a use position is. Here, a pouring opening is arranged in the closure lower part and the closure lid has means for opening the pouring opening in the position of use of the closure lid. The closure cap is hereby preferably folded onto the closure bottom part in order to open the can closure, wherein the pouring opening arranged in the closure bottom part is automatically opened.

Vorzugsweise ist die Ausgießöffnung in dem Verschlussunterteil vor dem erstmaligen Öffnen durch eine Abdeckung verschlossen, die mindestens eine Sollbruchstelle aufweist. Der Verschlussdekkel zerbricht diese Sollbruchstelle dann beim erstmaligen Schwenken von der Transportstellung in die Gebrauchsstellung, wodurch die Ausgießöffnung in dem Verschlussunterteil freigegeben wird.Preferably, the pouring opening is closed in the closure bottom before the first opening by a cover having at least one predetermined breaking point. The Verschlussdekkel then breaks this predetermined breaking point during the first pivoting from the transport position to the use position, whereby the pouring opening is released in the closure part.

Das Zerbrechen der Sollbruchstelle in dem Verschlussunterteil erfolgt vorzugsweise mittels einer Durchstoßrippe, die an der Unterseite des Verschlussdeckels angeordnet ist und gegen die Abdeckung der in dem Verschlussunterteil angeordneten Ausgießöffnung drückt, wenn der Verschlussdeckel aus der Transportstellung in die Gebrauchsstellung geschwenkt wird.The breakage of the predetermined breaking point in the closure lower part is preferably effected by means of a piercing rib which is arranged on the underside of the closure lid and presses against the cover of the pouring opening arranged in the closure base when the closure lid is pivoted from the transport position into the use position.

Vorzugsweise weist diese Durchstoßrippe auf der dem Gelenk zugewandten Seite eine Anschrägung auf, wobei die Höhe der Durchstoßrippe entlang der Anschrägung zu dem Gelenk hin abnimmt.Preferably, this piercing rib has a bevel on the side facing the joint, whereby the height of the piercing rib decreases along the bevel towards the joint.

Zum einen wird dadurch verhindert, dass die Abdeckung der in dem Verschlussunterteil angeordneten Ausgießöffnung in der Gebrauchsstellung des Verschlussdeckels vollständig abreißt und möglicherweise in die Dose hinein fällt.On the one hand, this prevents the cover of the pouring opening arranged in the closure lower part from being completely torn off in the use position of the closure lid and possibly falling into the can.

Zum anderen wird die Abdeckung der in dem Verschlussunterteil angeordneten Ausgießöffnung durch die Anschrägung der Durchstoßrippe in einer verschwenkten Lage gehalten, in der die Ausgießöffnung in dem Verschlussunterteil stets geöffnet bleibt.On the other hand, the cover of the pouring opening arranged in the closure lower part is held in a pivoted position by the chamfer of the piercing rib, in which the pouring opening in the closure lower part always remains open.

Darüber hinaus dient die in dem Verschlussdeckel angebrachte Durchstoßrippe vorzugsweise als Handhabe, um den Verschlussdekkel von der Transportstellung in die Gebrauchsstellung zu schwenken.In addition, the push-in rib provided in the closure lid preferably serves as a handle for pivoting the closure lid from the transport position to the use position.

Das Verschlussunterteil kann zur Befestigung an dem Dosendeckel eine umlaufende, vorzugsweise nutförmige Vertiefung aufweisen, in die der Mündungsrand eines in dem Dosendeckel angeordneten Ausschnittes formschlüssig eingreift.The closure lower part may have a circumferential, preferably groove-shaped recess for attachment to the can lid, in which the mouth edge of a cutout arranged in the can lid engages in a form-fitting manner.

Es ist jedoch fertigungstechnisch günstiger, das Verschlussunterteil mittels eines Kunststoffspritzvorgangs mit dem Dosendekkel zu verbinden.However, it is manufacturing technology cheaper to connect the closure bottom by means of a plastic injection process with the Dosendekkel.

Darüber hinaus besteht auch die Möglichkeit, dass das Verschlussunterteil mit dem Dosendeckel durch eine Ultraschallverschweissung verbunden ist.In addition, there is also the possibility that the closure base is connected to the can lid by an ultrasonic welding.

Vorzugsweise weist der erfindungsgemäße Dosenverschluss an seiner Unterseite oder an der Unterseite des Verschlussunterteils eine Oberflächenkonturierung auf, um bei einem Kunststoffspritzvorgang eine formschlüssige, innige Verbindung mit einer entsprechenden Oberflächenkonturierung an dem Dosendeckel zu bilden. Eine derartige Oberflächenkonturierung kann beispielsweise aus kleinen Erhebungen, Vertiefungen oder Bohrungen bestehen, die in dem Dosendeckel am Rand des Ausschnitts für das Verschlussunterteil angeordnet sind.The can closure according to the invention preferably has a surface contouring on its underside or on the underside of the closure bottom part, in order to form a form-fitting, intimate connection with a corresponding surface contouring on the can lid during a plastic injection process. Such a surface contouring can for example consist of small elevations, depressions or holes, which are arranged in the can lid at the edge of the cutout for the closure bottom.

Weiterhin bleibt der Verschlussdeckel bei dem erfindungsgemäßen Dosenverschluss nach dem Schwenken von der Transportstellung in die Gebrauchsstellung vorzugsweise selbständig in der Gebrauchsstellung. Dies kann beispielsweise dadurch erreicht werden, dass der Verschlussdeckel mit dem Verschlussunterteil eine Presspassung bildet. Es ist jedoch alternativ auch möglich, dass das Verschlussunterteil und der Verschlussdeckel Rastelemente aufweisen, um in der Gebrauchsstellung des Verschlussdeckels eine Rastverbindung zwischen dem Verschlussunterteil und dem Verschlussdeckel zu bilden, damit der Verschlussdeckel selbständig in der Gebrauchsstellung bleibt.Furthermore, in the case of the can closure according to the invention, the closure lid preferably remains independently in the position of use after pivoting from the transport position into the use position. This can be achieved, for example, in that the closure lid forms a press fit with the closure bottom part. However, it is alternatively also possible for the closure bottom part and the closure lid to have latching elements in order to form a latching connection between the closure bottom part and the closure lid in the position of use of the closure lid so that the closure lid remains in the use position independently.

Darüber hinaus ist der erfindungsgemäße Dosenverschluss nach dem erstmaligen Öffnen vorzugsweise wieder verschließbar. Hierzu kann eine Verschlussklappe vorgesehen sein, die an dem Verschlussdeckel angeordnet ist und beispielsweise durch ein Gelenk, wie ein Filmscharnier, relativ zu dem Verschlussdeckel verschwenkt werden kann.In addition, the can closure according to the invention is preferably resealable after the first opening. For this purpose, a closure flap may be provided, which is arranged on the closure lid and, for example, can be pivoted relative to the closure lid by a hinge, such as a film hinge.

Schließlich umfasst die Erfindung auch eine Dose mit einem erfindungsgemäßen Dosenverschluss.Finally, the invention also includes a can with a can closure according to the invention.

Die Figuren 1 bis 5 zeigen einen aus Kunststoff hergestellten Dosenverschluss 1, der im wesentlichen aus einem Verschlussunterteil 2 und einem Verschlussdeckel 3 besteht.FIGS. 1 to 5 show a can closure 1 made of plastic, which consists essentially of a closure bottom 2 and a closure lid 3.

Das Verschlußunterteil 2 ist über ein Gelenk 4 mit dem Verschlußdeckel 3 verbunden, wobei das Gelenk 4 aus einem Filmscharnier besteht.The closure lower part 2 is connected via a hinge 4 with the closure lid 3, wherein the hinge 4 consists of a film hinge.

Bei der Montage wird das Verschlussunterteil 2 - wie später erläutert wird - in einem seiner Form angepassten Ausschnitt 5 innerhalb eines Dosendeckels 6 einer Dose 7 befestigt.During assembly, the closure bottom 2 - as will be explained later - attached in a shape adapted cutout 5 within a can lid 6 a can 7.

Das Verschlussunterteil 2 weist eine Ausgießöffnung 8 auf, die im Transportzustand der Dose 7 (siehe Fig. 2) mittels einer Abdeckung 9 in Form einer Durchstoßfläche versehen ist. Diese Abdeckung 9 ist in ihren die Ausgießöffnung 8 begrenzenden Bereichen über dünnwandige Sollbruchstellen 10 mit dem Verschlussunterteil 2 verbunden, während ein der Ausgießöffnung 8 gegenüberliegender Bereich der Abdeckung 9 als Filmscharnier 11 gestaltet ist und nach dem Durchstoßen als Gelenk wirkt.The closure bottom part 2 has a pouring opening 8, which is provided in the transport state of the can 7 (see FIG. 2) by means of a cover 9 in the form of a puncture area. This cover 9 is connected in its the pouring 8 limiting areas on thin-walled predetermined breaking points 10 with the closure part 2, while a pouring opening 8 opposite region of the cover 9 is designed as a film hinge 11 and acts as a joint after piercing.

Der Verschlussdeckel 3 ist ebenfalls mit einer Ausschüttöffnung 12 versehen, die im Gebrauchszustand der Dose 7 mittels einer angelenkten Verschlussklappe 13 wieder verschließbar ist. Im Mittelbereich der Ausschüttöffnung 12 in dem Verschlussdeckel 3 ist eine die Ausschüttöffnung 12 senkrecht übergreifende Durchstoßrippe 14 angeordnet, auf deren Funktion später eingegangen wird.The closure lid 3 is also provided with a discharge opening 12, which in the use state of the can 7 by means of a hinged flap 13 is closed again. In the middle region of the discharge opening 12 in the closure lid 3, a pouring rib 14 which extends vertically over the pouring opening 12 is arranged, whose function will be discussed later.

Figur 2 zeigt den in den Dosendeckel 6 der Dose 7 integrierten Dosenverschluss 1, wobei die Abdeckung 9 noch mit dem Verschlussunterteil 2 verbunden ist. Wie ferner aus dieser Figur zu ersehen ist, befindet sich in dem Dosendeckel 6 der Ausschnitt 5, in den das Verschlussunterteil 2 mittels eines Spritzvorgangs eingebracht und somit formschlüssig in dem Dosendeckel 6 gehaltert ist. Hierbei besteht die Möglichkeit, an den Innenkonturen des Ausschnittes 5 kleinere Erhebungen bzw. Vertiefungen oder kleine Bohrungen vorzusehen, um eine innige Verbindung zwischen dem Verschlussunterteil 2 und dem Dosendeckel 6 herzustellen.FIG. 2 shows the can closure 1 integrated in the can lid 6 of the can 7, the cover 9 still being connected to the closure bottom part 2. As can also be seen from this figure, located in the can lid 6 of the neck 5, in which the closure part 2 is introduced by means of an injection process and thus positively held in the can lid 6. In this case, it is possible to provide on the inner contours of the cutout 5 smaller elevations or depressions or small bores in order to produce an intimate connection between the closure bottom part 2 and the can lid 6.

Der Dosendeckel 6 besitzt ferner eine den Konturen des Verschlussdeckels 3 angepasste Vertiefung 15, in die der Verschlussdeckel 3 im Transportzustand der Dose 7 eingebracht wird. Dadurch ist es möglich, mehrere Dosen 7 zu Transportzwecken übereinander zu stapeln, ohne dass sich der Verschluss 1 störend auf die Stapelhöhe auswirkt. Die Vertiefung 15 ist deshalb so tief, dass der Verschlussdeckel 3 in der Transportstellung nicht über den Rand der Dose 7 nach oben hinausragt.The can lid 6 also has a contour of the closure lid 3 adapted recess 15, in which the closure lid 3 is introduced in the transport state of the can 7. This makes it possible to stack a plurality of cans 7 for transport purposes one above the other, without the closure 1 interfering with the stack height. The depression 15 is therefore so deep that the closure lid 3 does not project beyond the edge of the can 7 in the transport position.

In der in den Figuren 4 und 5 gezeigten Gebrauchsstellung der Dose 7 ist der Verschlussdeckel 3 durch Ziehen an der Durchstoßrippe 14 aus der Vertiefung 15 des Dosendeckels 6 entfernt und in Richtung auf das Verschlussunterteil 2 verschwenkt worden. Bei diesem Vorgang wird mittels der Durchstoßrippe 14, die im Bereich des Gelenks 4 eine Anschrägung 16 (siehe Figur 3) aufweist, die Abdeckung 9 aufgrund ihrer Sollbruchstellen 10 soweit in Richtung Doseninneres gedrückt, bis die Abdeckung 9 an der Anschrägung 16 des Verschlussdeckels 3 zur Anlage gelangt. Die Abdeckung 9 verschwenkt dabei um den Bereich 8 zwischen dem Verschlussunterteil 2 und der Abdeckung 9. In diesem Zustand verrastet der Verschlussdeckel 3 mit dem Verschlussunterteil 2.In the position of use of the can 7 shown in FIGS. 4 and 5, the closure lid 3 has been removed from the depression 15 of the can lid 6 by pulling on the piercing rib 14 and has been pivoted in the direction of the closure bottom 2. In this process, by means of the piercing rib 14, which has a chamfer 16 in the region of the joint 4 (see FIG. 3), the cover 9 is pressed in the direction of the can interior due to its predetermined breaking points 10 until the cover 9 against the chamfer 16 of the closure cap 3 Plant arrives. In this case, the cover 9 pivots about the region 8 between the closure bottom part 2 and the cover 9. In this state, the closure lid 3 locks with the closure bottom part 2.

Aus Figur 5 kann ferner ein an dem Verschlussunterteil 2 angeordneter, umlaufender Rastrand 17 ersehen werden, der mit einer an dem Verschlussdeckel 3 angeordneten, ebenfalls umlaufenden Rastaufnahme 18 zusammenwirkt.From Figure 5, a arranged on the closure part 2, circumferential locking edge 17 can also be seen, which cooperates with a arranged on the closure lid 3, also circumferential locking receptacle 18.

Die Ausschüttöffnung 12 in dem Verschlussdeckel 3 wird mittels der einen Wiederverschluss gestattenden Verschlussklappe 13 abgedeckt. In der in den Figuren 4 und 5 gezeigten Gebrauchslage der Dose 7 kann über die Ausgießöffnung 8 und die Ausschüttöffnung 12 die in der Dose 7 vorhandene Flüssigkeit entnommen werden, wobei durch die Durchstoßrippe 9 die Dosierung der Flüssigkeit beeinflusst werden kann. Nach Beendigung des Ausschüttvorgangs wird die Ausschüttöffnung 12 des Verschlussdeckels 3 mittels der Verschlussklappe 13 abgedeckt. Auch diese Verschlussklappe 13 kann mit dem Verschlussdeckel 3 über ein Filmscharnier 19 schwenkbar verbunden sein und verrastet mit dem Verschlussdeckel 3 im aufgedrückten Zustand.The discharge opening 12 in the closure lid 3 is covered by means of the closure flap 13 which permits re-closure. In the position of use of the can 7 shown in FIGS. 4 and 5, the liquid present in the can 7 can be withdrawn via the pouring opening 8 and the pouring opening 12, whereby the metering of the liquid can be influenced by the piercing rib 9. After completion of the dispensing operation, the discharge opening 12 of the closure lid 3 is covered by means of the closure flap 13. This closure flap 13 can also be pivotably connected to the closure lid 3 via a film hinge 19 and latched to the closure lid 3 in the pressed-on state.

Zur angenehmeren Handhabung weist der Verschlussdeckel 3 ferner einen griffartigen Ansatz 20 auf, mit dem der Verschlussdeckel 3 wieder von dem Verschlussunterteil 2 entfernt werden kann.For more pleasant handling, the closure lid 3 also has a handle-like projection 20, with which the closure lid 3 can be removed again from the closure base 2.

Das in den Figuren 6 bis 13 dargestellte Ausführungsbeispiel eines erfindungsgemäßen Dosenverschlusses 1' stimmt weitgehend mit dem vorstehend beschriebenen und in den Figuren 1 bis 5 dargestellten Ausführungsbeispiel überein, so dass im Folgenden zur Vermeidung von Wiederholungen weitgehend auf die vorstehende Beschreibung verwiesen wird und für entsprechende Bauteile dieselben Bezugszeichen verwendet werden, die zur Unterscheidung lediglich durch ein Apostroph gekennzeichnet sind.The exemplary embodiment of a can closure 1 'according to the invention illustrated in FIGS. 6 to 13 is largely identical to the exemplary embodiment described above and illustrated in FIGS. 1 to 5, so that reference is made to the above description to avoid repetition and to corresponding components the same reference numerals are used, which are marked for distinction only by an apostrophe.

Eine Besonderheit dieses Ausführungsbeispiels besteht darin, das in dem Verschlussunterteil 2' eine schlitzförmige Vertiefung 21' angeordnet ist, die vor der erstmaligen Öffnung an ihrer Unterseite durch eine Abdeckung 22' abgedeckt ist, wobei die Abdekkung 22' durch Soll-Bruchstellen mit dem Verschlussunterteil 2' verbunden ist. Beim Schwenken des Verschlussdeckels 3' von der in den Figuren 6, 8, 9, 10 dargestellten Transportstellung in die in Figur 7 dargestellte Gebrauchsstellung wird die Durchstoßrippe 14' in die schlitzförmige Vertiefung eingeführt und zerbricht dabei die Sollbruchstellen zwischen der Abdeckung 22' an der Unterseite der schlitzförmigen Vertiefung 21' und dem Verschlussunterteil 2', wodurch eine Ausgießöffnung freigegeben wird.A special feature of this embodiment is that in the closure part 2 'a slot-shaped recess 21' is arranged, which is covered before the initial opening on its underside by a cover 22 ', wherein the Abdekkung 22 'is connected by predetermined breaking points with the closure lower part 2'. When pivoting the closure lid 3 'of the transport position shown in Figures 6, 8, 9, 10 in the position of use shown in Figure 7, the piercing rib 14' is inserted into the slot-shaped depression and thereby breaks the predetermined breaking points between the cover 22 'at the bottom the slot-shaped recess 21 'and the closure lower part 2', whereby a pouring opening is released.

Darüber hinaus ist aus Figur 8 ersichtlich, das an der Unterseite des Verschlussunterteils 2' kleine Erhebungen 23' angeformt sind, die im montierten Zustand in entsprechende Vertiefungen 24' eingreifen, die in dem Verschlussdeckel 3' im Rand des Ausschnitts 5' für das Verschlussunterteil 2' angebracht sind, wie insbesondere aus den Figuren 13 und 14 ersichtlich ist. Die Erhebungen 23' an dem Verschlussunterteil 2' führen in Verbindung mit den Bohrungen 24' in dem Verschlussdeckel 3' zu einer formschlüssigen Verbindung.In addition, it can be seen from FIG. 8 that small elevations 23 'are formed on the lower side of the closure lower part 2', which engage in corresponding recesses 24 'in the assembled state, which in the closure lid 3' in the edge of the cutout 5 'for the closure lower part 2 'are attached, as can be seen in particular from Figures 13 and 14. The elevations 23 'on the closure lower part 2' lead in conjunction with the bores 24 'in the closure lid 3' to a positive connection.

Das in den Figuren 14 und 15 dargestellte Ausführungsbeispiel eines erfindungsgemäßen Dosenverschlusses 1" stimmt weitgehend mit den vorstehend beschriebenen Ausführungsbeispielen überein, so dass zur Vermeidung von Wiederholungen auf die vorstehende Beschreibung verwiesen wird und im folgenden für entsprechende Bauteile dieselben Bezugszeichen verwendet werden, die lediglich zur Unterscheidung durch zwei Apostrophe gekennzeichnet sind.The exemplary embodiment of a can closure 1 "according to the invention shown in FIGS. 14 and 15 largely corresponds to the exemplary embodiments described above, so that reference is made to the above description to avoid repetition, and the same reference numerals are used below for corresponding components which are merely for the purpose of distinction are indicated by two apostrophes.

Eine Besonderheit dieses Ausführungsbeispiels besteht darin, dass das Verschlussunterteil 2" aus zwei Kunststoffkomponenten besteht, die eine unterschiedliche Härte aufweist. Die härtere Kunststoffkomponente bildet hierbei eine Dichtung 25", die im montierten Zustand am Rand des Ausschnitts in dem Dosendeckel aufliegt und den Ausschnitt dadurch abdichtet.A special feature of this exemplary embodiment is that the closure bottom part 2 "consists of two plastic components that have a different hardness.The harder plastic component forms a seal 25", which rests in the can lid in the mounted state at the edge of the cutout and thereby seals the cutout ,

Darüber hinaus verhindert die Dichtung 25" auch eine Korrosion am Rand des Ausschnitts des Dosendeckels, indem die Dichtung 25" den Ausschnittrand umschließt. Dies ist vorteilhaft, da das Ausstanzen des Ausschnitts die Schutzlackschicht auf dem Dosenblech beschädigt und damit korrosionsanfällig macht.In addition, the seal 25 "also prevents corrosion at the edge of the cut-out of the can lid by the seal 25" enclosing the cut-out edge. This is advantageous since the punching out of the cutout damages the protective lacquer layer on the tin sheet and thus makes it susceptible to corrosion.

Die Erfindung ist nicht auf die vorstehend beschriebene bevorzugten Ausführungsbeispiele beschränkt. Vielmehr ist eine Vielzahl von Varianten und Abwandlungen möglich, die ebenfalls von dem erfindungsgemäßen Gedanken Gebrauch machen.The invention is not limited to the preferred embodiments described above. Rather, a variety of variants and modifications is possible, which also make use of the inventive concept.
