Abstract

Disclosed is a closing device comprising a container shoulder, a container head for applying the contents therein, and a closing cap, wherein said cap can be moved by using its rotational clamping function. Said closure, which is also known as a fractal closure, is provided for containers closed by a cap, irrespective of their size and embodiment, and which have a built-in container head with an opening to take out doseable media. According to the invention, threaded segments (1) are located in a narrow or optionally cylindrical base area (2) of the container head which is directly joined to the shoulder of the container (4). The application cone (3) follows onto the base area (2) of the container head which comprises the threaded area. The threaded segments (1), which are configured as a simple upward-winding thread, comprise few structural elements and are inconspicuous. Said segments can be configured as lines, dots or lugs. As a further characteristic of the invention, the cover plate (7) of the closure cap (5) has openings or windows (8) in the area of the inner cylinder (6) of the closure cap (5) and a closure lid (10) held by strips (9). Parts of a freshness seal (14) that is center-fixed on the face of the application cone (3) of the container head can be seen from the outside even when the container is closed. The windows (8, 12) on the closure can be provided in any number or shape. The advantages gained by making the freshness seal (14) visible are used to make savings in material and/or to provide a more advantageous design.

Description

Drehklemmverschluß für BehälterTwist lock for containers
Beschreibungdescription
Die Erfindung betrifft eine Verschließeinheit, bestehend aus Behälterschulter, Behälterkopf zur Applikation der Inhaltsstoffe und einer Verschlußkappe, wobei die Verschlußkappe unter Nutzung der Drehklemmfunktion bedient wird.The invention relates to a closing unit, consisting of a container shoulder, a container head for applying the ingredients and a closure cap, the closure cap being operated using the twist-lock function.
Ein solcher Verschluß, auch als Fraktalverschluß bekannt, ist vorgesehen für einen mittels einer Kappe zu verschließenden Behälter beliebiger Dimension und Ausführungsart, der einen integrierten Behälterkopf mit einer Öffnung zur Entnahme dosierbarer Medien besitzt.Such a closure, also known as a fractal closure, is provided for a container of any dimension and design to be closed by means of a cap, which has an integrated container head with an opening for the removal of meterable media.
Gattungsgemäße Verschlüsse sind aus DE 43 42 251 Cl und GB 2203 729 bekannt. Bei diesen Lösungen sind über den Umfang des Behälterhalses bzw. Behälterkopfes Gewindegangabschnitte verteilt, die mit analogen Gewindegangabschnitten der Verschlußkappe korrespondieren.Closures of the generic type are known from DE 43 42 251 Cl and GB 2203 729. In these solutions, thread sections are distributed over the circumference of the container neck or container head, which correspond to analog thread sections of the closure cap.
Dabei weist jeder Gewindegangabschnitt zusätzlich einen Steg oder andere Klemmelemente auf, über den bzw. über die nach kurzer Drehbewegung die Klemmwirkung der Verschlußkappe auf dem Behälterkopf erzielt wird.Each thread section additionally has a web or other clamping elements, via which or after a short rotational movement the clamping effect of the closure cap on the container head is achieved.
Aufgabe der Erfindung ist es, den Verschlußmechanismus zu vereinfachen und den Gewindebereich auf eine möglichst schmale, unauffällige Zone am Behälterkopf zu begrenzen. Des weiteren ist es Aufgabe der Erfindung den Erstverbraucherschutz, also das Frischesiegel so in der Verschlußeinheit anzuordnen, daß es für den Nutzer von außen sichtbar ist.The object of the invention is to simplify the locking mechanism and to limit the thread area to a narrow, unobtrusive zone on the container head. Furthermore, it is an object of the invention to arrange the first consumer protection, that is to say the freshness seal, in the closure unit in such a way that it is visible to the user from the outside.
Eine erfindungsgemäße Lösung dieser Aufgabe ist im Patentanspruch 1 angegeben. Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnetAn inventive solution to this problem is specified in claim 1. Developments of the invention are characterized in the subclaims
Nach der erfindungsgemäßen Konzeption befinden sich die Gewindesegmente in einem schmalen, ggf. zylindrischen Fußbereich des Behälterkopfes, der unmittelbar an der Behälterschulter anschließt. Auf diesen Fußbereich des Behälterkopfes, der die Gewindezone beinhaltet, folgt dann der Applizierkonus.According to the concept according to the invention, the thread segments are located in a narrow, possibly cylindrical foot area of the container head, which directly adjoins the container shoulder. The application cone then follows this foot area of the container head, which contains the thread zone.
Die als einfaches Steiggewinde ausgeführten Gewindesegmente können dabei linien-, punkt- oder zapfenförmig ausgebildet sein. Die Gewindesegmente sollen ohne Kanten und dgl., sondern nur mit Rundungen ausgeführt werden.The thread segments designed as a simple rising thread can be linear, point-shaped or peg-shaped. The thread segments should be executed without edges and the like, but only with curves.
Der Behälterkopf hat im Bereich der Applizierzone eine kegelstumpfförmige Gestalt, wobei im unteren Bereich an der Behälterschulter die Gewindesegmente so angeordnet sind, daß sie beim Aufschrauben der Verschlußkappe in das im inneren Endbereich des Innenzylinders der Verschlußkappe vorhandene Gewinde eingreifen. Bei geringem Öffnungs- und Schließwinkel gewährleistet die in geschlossener Position auf der Behälterschulter aufsitzende Verschlußkappe gute Klemmeigenschaften zur zuverlässigen Fixierung des Verschlusses.The container head has a frustoconical shape in the area of the application zone, the threaded segments being arranged in the lower region on the container shoulder in such a way that, when the closure cap is screwed on, they engage in the thread present in the inner end region of the inner cylinder of the closure cap. With a small opening and closing angle, the closure cap that sits on the container shoulder in the closed position ensures good clamping properties for reliably fixing the closure.
Als weiteres Merkmal der Erfindung weist die Deckplatte der Verschlußkappe im Bereich des Innenzylinders der Verschlußkappe Durchbrüche bzw. Fenster und einen über Stege gehaltenen Verschlußdeckel auf. Dieser Verschlußdeckel ist als Verschließ- und Dichtfläche konzentrisch innerhalb der Deckplatte angeordnet und sein Durchmesser entspricht mindestens dem Durchmesser der Behälteröffnung, so daß der Verschlußdeckel im aufgeschraubten Zustand der Verschlußkappe die Applizieröffnung zuverlässig abdichtet. Durch die beschriebenen Fenster in der Deckplatte sind Teile des zentriert auf der Stirnseite des Applizierkonus des Behälterkopfes befestigten Frischesiegels auch im verschlossenen Zustand des Behälters von außen sichtbar. Der Durchmesser des Frischesiegels entspricht dabei etwa dem Durchmesser der Grundfläche des Applizierkonus.As a further feature of the invention, the cover plate of the closure cap has openings or windows in the region of the inner cylinder of the closure cap and a closure cover held over webs. This cap is arranged as a sealing and sealing surface concentrically within the cover plate and its diameter corresponds at least to the diameter of the container opening, so that the cap reliably seals the application opening when the cap is screwed on. Through the windows described in the cover plate, parts of the freshness seal, which is centered on the end face of the application cone of the container head, are visible from the outside even when the container is closed. The diameter of the fresh seal corresponds approximately to the diameter of the base of the application cone.
Durch die erfindungsgemäße Anordnung des Frischesiegels in Verbindung mit der beschriebenen Ausführung der Deckplatte der Verschlußkappe kann sich der Kunde bereits vor dem Erstgebrauch vom Vorhandensein des Frischesiegels und damit der Unversehrtheit der Produktverpackung überzeugen.The inventive arrangement of the fresh seal in conjunction with the described design of the cover plate of the closure cap enables the customer to convince himself of the presence of the fresh seal and thus the integrity of the product packaging even before first use.
Auf der der Applizieröffnung des Behälterkopfes zugewandten Innenseite des Verschlußdeckels kann zur Verbesserung der Verschlußeigenschaften der Verschließeinheit eine Ringwulst oder dgl. vorgesehen werden, deren Außendurchmesser etwa dem Innendurchmesser der Behälteröffnung entspricht.On the inside of the closure lid facing the application opening of the container head, an annular bead or the like can be provided to improve the closure properties of the closure unit, the outer diameter of which corresponds approximately to the inner diameter of the container opening.
Form und Zahl der Fenster im Verschluß können beliebig sein. Was an Aussparungen über die Sichtbarmachung des Frischesiegels hinausgeht, dient der Materialeinsparung und/oder einem vorteilhafteren Design.The shape and number of windows in the lock can be any. Any recesses that go beyond making the freshness seal visible serve to save material and / or a more advantageous design.
Zum Erstgebrauch wird der Verschluß durch maximal 90°-Drehung und das Frischesiegel durch Abziehen entfernt. Der zuverlässige Festsitz des Verschlusses ist durch die Steigung, die Materialstärke des Gewindesegments und die Klemmung auf der Behälterschulter gewährleistet. Das Losreißmoment beim Öffnungsvorgang ist gering.For first use, the closure is removed by a maximum of 90 ° rotation and the fresh seal by pulling it off. Reliable tightness of the closure is guaranteed by the pitch, the material thickness of the thread segment and the clamping on the container shoulder. The breakaway torque during the opening process is low.
Als weitere Vorteile der Erfindung können genannt werden. Der Behälterkopf mit dem ausgeprägten Applizierkonus und dem kantenlos strukturierten Gewinde ist leichter zu reinigen; durch die möglichst flach gehaltene Behälterschulter ist für nicht dimensionsstabile Behälter eine gute Restentleerbarkeit gegeben. Hervorzuhebende Eigenschaften des Verschlusses sind weiterhin die große Standfläche, der minimierte Materialeinsatz, der dimensionsstabile Innenzylinder mit Gewindesegmentgegenstück und die Ringwulst, auch zur Verpressung und Dichtung des Frischesiegels, zu nennen; des weiteren gibt es keine Materialhmterschneidungen, wodurch eine einfache Fertigung gewährleistet ist.Further advantages of the invention can be mentioned. The container head with the pronounced application cone and the edgeless structured thread is easier to clean; due to the container shoulder being kept as flat as possible, good residual emptying is ensured for non-dimensionally stable containers. The properties of the fastener to be emphasized are still the great ones Footprint, the minimized use of materials, the dimensionally stable inner cylinder with threaded segment counterpart and the ring bead, also for pressing and sealing the freshness seal; furthermore, there are no material hammer cuts, which ensures simple manufacture.
