Description

Die Erfindung betrifft einen Kunststoff-Schraubdeckel nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a plastic screw cap the preamble of claim 1.

Ein solcher Schraubdeckel ist beispielsweise aus DE 43 44 588 A1 bekannt.Such a screw cap is, for example DE 43 44 588 A1 known.

Hiervon ausgehend beschäftigt sich die Erfindung mit dem Problem, die radial federnde Lagerung des Filtereinsatzes an dem Schraubdeckel zu versteifen. Dabei sollen die Schnapp­ verschlußmittel nicht fester Bestandteil des Ringfilterein­ satzes sein müssen, damit diese bei einem Austausch des Fil­ tereinsatzes an dem Schraubdeckel insgesamt verbleiben kön­ nen. Bei der zuletztgenannten Ausführung werden die bei ei­ nem Filterwechsel anfallenden Wegwerf- beziehungsweise zu entsorgenden Materialmengen verringert. Das austauschbare Ringfilterelement soll möglichst einfach und kostengünstig ausgebildet sein. Proceeding from this, the invention deals with the Problem, the radially resilient mounting of the filter insert stiffen the screw cap. The snap should sealing means not an integral part of the ring filter must be set so that when the fil The insert can remain on the screw cap as a whole nen. In the latter version, the ei disposable or too quantities of material disposed of. The interchangeable Ring filter element should be as simple and inexpensive as possible be trained.  

Eine Lösung hierzu zeigt eine Ausführung nach den kennzeich­ nenden Merkmalen des Patentanspruchs 1 auf.A solution to this is shown by an execution according to the marks nenden features of claim 1.

Aus EP 0 612 549 A2 ist bereits ein Schraubdeckel bekannt, in dem ein Filtereinsatz über ein Halteteil mittels eines Schnappverschlusses in dem Schraubdeckel gelagert ist. Das Halteteil ist dort jedoch nicht radial mit Hilfe eines Zen­ triermittels unelastisch gestützt. Aus DE 27 42 610 A1 ist ebenfalls ein in einem Schraubdeckel über einen Schnappver­ schluß gelagertes Filterelement bekannt. Auch dort erfolgt die Lagerung des Filtereinsatzes über ein in einem Schnapp­ verschluß an dem Deckel gelagertes Halteteil. Radiale Zen­ triermittel, die eine elastische radiale Verschiebung der Schnappverschlußmittel gegeneinander verhindern, sind auch dort nicht vorhanden.A screw cap is already known from EP 0 612 549 A2, in which a filter insert over a holding part by means of a Snap lock is stored in the screw cap. The However, the holding part is not radial there with the help of a Zen means of elastic support. From DE 27 42 610 A1 also one in a screw cap over a snap latch finally stored filter element known. Also done there the storage of the filter insert in a snap Closure part held on the lid. Radial zen trier means that an elastic radial displacement of the Preventing snap fasteners against each other are also not available there.

Zweckmäßige Ausgestaltungen der Erfindung nach Anspruch 1 sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention according to claim 1 are the subject of the subclaims.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.An embodiment is shown in the drawing.

Fig. 1 einen Ausschnitt aus einem Filtergehäuse mit ei­ nem aufgeschraubten Deckel im Längsschnitt, Fig. 1 shows a detail of a filter housing with egg nem screwed cap in longitudinal section;

Fig. 2 einen Schnitt durch den Deckel wie in Fig. 1 oh­ ne eingesetzte Teile, Fig. 2 shows a section through the lid shown in Fig. 1 oh ne used parts,

Fig. 3 eine Draufsicht auf den Deckel nach Fig. 2. Fig. 3 is a plan view of the cover of FIG. 2.

Auf ein Filtergehäuse 1 ist ein Schraubdeckel 2 aufge­ schraubt.On a filter housing 1 , a screw cap 2 is screwed up.

Zum Montieren und Demontieren des Schraubdeckels 1 besitzt dieser ein Ansatzstück 3 zum Ansetzen eines Werkzeuges. Das Ansatzstück 3 besteht dabei aus einem an den Boden des Schraubdeckels 2 angeformten Rohrstutzen 4 mit einem Sechs­ kantaußenprofil. Direkt im Zentrum des Schraubdeckels 2 ist an dessen Boden axial nach außen ein Ansatz 5 angeformt. In den Innenraum des Rohrstutzens 4 ist radial innen und außen formschlüssig ein Stopfen 6 eingeschoben. Dieser Stopfen 6 hat die Form eines Pilzes, wobei der Pilzkopf sich in einge­ schobenem Zustand des Stopfens auf dem Rohrstutzen 4 nach außen radial formschlüssig abschließend abstützt. Der Stop­ fen 6 ist derart in den Rohrstutzen 4 eingeschoben, daß kei­ ne Materialverspannungen in dem Rohrstutzen 4 auftreten. An­ dererseits ist der Sitz derart, daß der Stopfen 6 dauerhaft Halt in dem Rohrstutzen 4 besitzt. Hierfür kann beispiels­ weise eine Rastverbindung gewählt werden von der ein Rast­ element 11 im Inneren des Rohrstutzens 4 in Fig. 2 gezeigt ist. Der Stopfen 6 ist bevorzugt wie der Schraubdeckel 2 ebenfalls aus Kunststoff.To assemble and disassemble the screw cap 1 , this has an extension piece 3 for attaching a tool. The extension 3 consists of a molded on the bottom of the screw cap 2 pipe socket 4 with a six edge profile. Directly in the center of the screw cap 2 an extension 5 is formed axially on the bottom thereof. In the interior of the pipe socket 4 , a plug 6 is inserted radially inside and outside. This plug 6 has the shape of a mushroom, with the mushroom head is supported radially in schobenem inserted state of the plug on the pipe stub 4 to the outside form-fitting exhaustive. The stop fen 6 is inserted into the pipe socket 4 in such a way that no material stresses occur in the pipe socket 4 . On the other hand, the seat is such that the plug 6 has a permanent hold in the pipe socket 4 . For this purpose, for example, a locking connection can be selected from which a locking element 11 is shown in the interior of the pipe socket 4 in Fig. 2. The stopper 6 , like the screw cap 2, is preferably also made of plastic.

Zentral im Inneren des Schraubdeckels 2 ist ein Rundbolzen 7 angeformt, der zur Aufnahme und radial unelastischen Lage­ rung einer Verschlußkappe 8 an der Stirnseite eines Ringfil­ tereinsatzes 9 dient. Die Verschlußkappe 8 ist etwa spiel­ frei drehbar an dem Rundbolzen 7 gelagert. Axial fixiert ist die Verschlußkappe 8 über auf ihrem Außenumfang auf einen umlaufenden Ringsteg aufgeschnappte von dem Schraubdeckel 2 ausgehende Haltebügel 10 aus radial verformbarem Material. Innerhalb dieser Schnappverbindung ist die Verschlußkappe 8 gegenüber dem Schraubdeckel 2 drehbar. Auf einen zylindri­ schen Bereich der Verschlußkappe 8 ist radial gedichtet der Ringfiltereinsatz 9 aufschiebbar.A round bolt 7 is integrally formed in the center of the screw cap 2 , which serves to accommodate and radially inelastic position of a closure cap 8 on the end face of a ring insert 9 . The closure cap 8 is mounted on the round bolt 7 such that it can rotate freely. The closure cap 8 is axially fixed by means of retaining brackets 10 made of radially deformable material and snapped onto a circumferential ring web on its outer circumference and extending from the screw cap 2 . Within this snap connection, the closure cap 8 can be rotated with respect to the screw cap 2 . On a cylindri's area of the cap 8 , the ring filter insert 9 is radially sealed.

Durch den Stopfen 6 innerhalb des Rohrstutzens 4 werden Kräfte eines Montagewerkzeuges über einen größeren Bereich verteilt, so daß die Wanddicke des Rohrstutzens 4 insgesamt und insbesondere im Übergangsbereich zu dem Boden des Schraubdeckels äußerst gering sein kann.Forces of an assembly tool are distributed over a larger area by the plug 6 within the pipe socket 4 , so that the wall thickness of the pipe socket 4 as a whole and in particular in the transition region to the bottom of the screw cap can be extremely small.
