Abstract

1. A screw-closure container, in which the container neck possesses a helically-configured groove, into which a helically-configured keying feature can be screwed this keying feature belonging to the closure cap wherein the groove (4) runs, in the region of the opening in the container (1), into a lead-in spiral (7) which possesses a flattened area (8), while the keying feature (5) merges, in the base of the closure cap, into a web (6) which engages into the lead-in spiral (7) in a manner effecting positive mechanical locking.

Description

Gegenstand der Erfindung ist ein Behälter mit einrastendem Schraubverschluß, bei dem der Behälterhals eine wendelförmig angeordnete Nut und die Verschlußkappe eine in die Nut eindrehbare wendelformig angeordnete Feder aufweist.The invention relates to a container with a locking screw closure, in which the container neck has a helically arranged groove and the closure cap has a helically arranged spring which can be screwed into the groove.

Einrastende Schraubverschlüsse sind häufig erwünscht, wenn unbeabsichtigtes öffnen des Behälters vermieden werden soll. Es sind flache Behälter mit einrastendem Schraubverschluß bekannt, bei denen Behälter und Verschlußkappe sich zu einer Kontur ergänzen. Darüber hinaus ist der Behälter mit einer Schulter versehen, die im verschlossenen Zustand durch die Verschlußklappe verdeckt wird. Beim öffnen des Behälters muß daher diese Schulter erst durch den Rand der Verschlufkappe überwunden werden. Hierbei deformiert sich die Verschlußkappe. Nachteilig ist, daß die Rastung der Verschlußkappe stets eine im Querschnitt rechteckig ausgeführte Schulter am Behälter erforderlich macht. Darüber hinaus muß sich die Wandung der Verschlußkappe elastisch verformen lassenSnap-in screw caps are often desirable if the container is to be opened unintentionally. Flat containers with a locking screw closure are known, in which the container and the closure cap complement each other to form a contour. In addition, the container is provided with a shoulder, which is covered by the closure flap when closed. When opening the container, this shoulder must therefore first be overcome by the edge of the sealing cap. Here, the cap deforms. A disadvantage is that the locking of the closure cap always requires a shoulder with a rectangular cross section on the container. In addition, the wall of the cap must be able to be elastically deformed

Es stelltesich daher die Aufgabe, einen einrastenden SchraubverschluB zu schaffen, der universell, d.h. unabhängig von der äußeren Form des Behälters wirksam ist.It is therefore the task of creating a snap-in screw cap that is universal, i.e. is effective regardless of the external shape of the container.

Die Aufgabe wird durch einen Behälter mit Schraubverschluß gelöst, bei dem der ßehältechals eine wendelförmig angeordnete Nut und die. verschlußkappe eine in die Nut eindrehbare wendelförmig angeordnete Feder aufweist, der dadurch gekennzeichnet ist, daß die Nut im Bereich der Öffnung des Behälters in eine Einlaufspirale mit Abflachung einmündet und die Feder im Verschlußkappengrund in einen in die Einlaufspirale formschlüssig eingreifenden Steg übergeht.The object is achieved by a container with a screw cap, in which the ßehältechals a helically arranged groove and the. Closure cap has a helically arranged spring which can be screwed into the groove and is characterized in that the groove in the region of the opening of the container into an inlet spiral opens out with a flattened portion and the spring in the base of the cap changes into a web that engages in a form-fitting manner in the inlet spiral.

Es kann von Vorteil sein, zwei gegenüberliegend angebrachte Nuten am Hals bzw. Federn in der Verschlußkappe in entsprechende Einlaufspiralen münden bzw. Stege übergehen zu lassen. Die Nuten und Federn können so angeordnet sein, daß der Behälter durch eine Relativdrehung der Verschlußkappe um 90° verschlossen bzw. geöffnet werden kann. Das hat den Vorteil, daß bei Behältern und Verschlußkappen mit rechteckigem Querschnitt die Verschlußkappe beim Verschließen stets in die richtige Position zum Behälter kommt. Selbstverständlich können die Nuten auch in der Verschlußkappe und die Federn am Hals des Behälters angeordnet sein.It can be advantageous to have two opposing grooves on the neck or springs in the cap open into corresponding inlet spirals or to allow webs to pass over. The grooves and tongues can be arranged so that the container can be closed or opened by a relative rotation of the closure cap by 90 °. This has the advantage that, in the case of containers and caps with a rectangular cross section, the cap always comes into the correct position with respect to the container when it is closed. Of course, the grooves can also be arranged in the closure cap and the springs on the neck of the container.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellenden Zeichnungen näher erläutert. Es zeigt

  • . Figur 1 einen im Verhältnis Breite : Dicke flachen Behälter in Seitenansicht und zwar im Bereich des Schraubverschlusses und
  • Figur 2 den gleichen Behälter wie in Figur 1 jedoch 90° um die Behälterachse gedreht.
The invention is explained in more detail below with the aid of drawings which illustrate only one embodiment. It shows
  • . Figure 1 shows a ratio of width: thick flat container in side view, in the area of the screw cap and
  • Figure 2 shows the same container as in Figure 1 but rotated 90 ° around the container axis.

Beim Behälter 1 ist der Behälterhals 3 mit zwei Nuten 4 versehen. In der Verschlußkappe 2 sind zwei Federn 5 angeordnet, die im Verschlußkappengrund in Stege 6 übergehen. Im verschlossenen Zustand greifen die Stege 6 in Einlaufspiralen 7 mit Abflachungen 8 formschlüssig ein. Es entsteht eine Hemmung bzw. Rastung, durch die unbeabsichtigtes öffnen der-Verscfilußhappe 2 verhindert wird. Die Hemmung ist unabhängig von der Gestaltung der Schulter des Behälters wirksam. Die Nuten 4 münden in diese Einlaufspiralen. 9 ist ein Pfropfen, der in den Hals 3 des Behälters ragt und den Behälter dicht verschließt. Nuten 4 und Federn 5 sind so angeordnet, daß die in etwa rechteckigen Querschnitt aufweisende Verschlußkappe 2 beim Verschließen des Behälters 90° verdreht gegenüber der Breitseite des Behälters angesetzt wird und der Verschließvorgang nach einer Vierteldrehung der Verschlußkappe gegenüber dem Behälter beendet ist. Die Breitseite der Verschlußkappe fluchtet dann mit der Breitseite des Behälters. Bei Behältern, bei denen solche Anforderungen nicht gestellt werden müssen, können die Nuten und Federn beliebig auf dem Umfang des Halses und im Innenumfang der Kappe angeordnet sein, sofern sichergestellt ist, daß Nuten und Federn zusammen wirken. Auch an die Steilheit des Gewindes sind keine besonderen Anforderungen zu stellen.In the case of the container 1, the container neck 3 is provided with two grooves 4. In the cap 2, two springs 5 are arranged, which merge into webs 6 in the base of the cap. In the closed state, the webs 6 positively engage in inlet spirals 7 with flats 8. There is an inhibition or detent by which unintentional opening of the Verscfilußhappen 2 is prevented. The inhibition is effective regardless of the design of the shoulder of the container. The grooves 4 open into these inlet spirals. 9 is a stopper which projects into the neck 3 of the container and seals the container tightly. Grooves 4 and springs 5 are arranged so that the approximately rectangular cross-section cap 2 is rotated 90 ° when closing the container against the broad side of the container and the closing process is completed after a quarter turn of the cap relative to the container. The broad side of the closure cap is then flush with the broad side of the container. For containers in which such requirements do not have to be made, the grooves and tongues can be arranged anywhere on the circumference of the neck and in the inner circumference of the cap, provided that it is ensured that the grooves and tongues act together. There are also no special requirements for the steepness of the thread.
