Abstract

The screw closure is for a bag (1), the open end of which, lightly held together, is pushed through the aperture of the clamping ring (2), folded and pushed down over a thread (4). The screw cap (5) is then screwed onto the clamping ring so that the annular cross-section between the screw cap cone and the sealing edge (3) of the clamping ring is free for suction. The mouthpiece (7) is pressed on the outer sealing surface (8) of the screw cap, and air is sucked out via apertures (6,9). When sufficient air has been extracted, the bag aperture is closed by twisting the mouthpiece along with the screw cap until the sealing cone is closed on the sealing edge.

Description

Gegenstand der Neuerung ist ein wiederverwendbarer Schraub­ verschluß für Folienbeutel, wie diese vorzugsweise im Haus­ halt zur Aufnahme von Lebensmitteln, z. B. für Gefrier-oder Kochzwecke Verwendung finden.The subject of the innovation is a reusable screw Closure for foil bags, such as these preferably in the house stop for food, e.g. B. for freezer or Find cooking uses.

Zum Verschließen und Evakuieren von solchen Beuteln sind bekannt: Folienschweißgeräte, Quetscheinrichtungen, stopfen­ ähnliche Verschlüsse mit Rückschlagventil, Drahtschlingen, etc.For closing and evacuating such bags Known: Foil sealers, squeeze devices, stuff Similar closures with check valve, wire loops, Etc.

Nachteile dieser bekannten Beutelverschlüsse sind beispiels­ weise: unsichere Funktion, umständliche Handhabung, zu teuer in der Herstellung.Disadvantages of these known bag closures are, for example wise: unsafe function, cumbersome handling, too expensive in the production.

Erfindungsgemäß wird daher die Aufgabe der Neuerung wie folgt gelöst:According to the invention, the task of innovation is therefore like solved as follows:

Fig. 1 zeigt die zusammengefügten Einzelteile in 2 Halbschnit­ ten. "A" zeigt den Verschluß in Absaugposition, "B" in Abdicht­ position. Fig. 1 shows the assembled parts in two half-sections. "A" shows the closure in the suction position, "B" in the sealing position.

Das offene, leicht zusammengehaltene obere Ende eines zu ver­ schließenden Beutels (1) wird durch die Öffnung des Klemm­ ringes (2) gesteckt, aufgefaltet und über das Gewinde (4) nach unten umgeschlagen. Danach wird die Schraubkappe (5) nur so weit auf den Klemmring geschraubt, daß der ringförmige Quer­ schnitt zwischen dem Konus der Schraubkappe und der Dicht­ kante (3) des Klemmringes zum Absaugen frei bleibt. The open, slightly held together upper end of a bag to be closed ( 1 ) is inserted through the opening of the clamping ring ( 2 ), unfolded and folded down over the thread ( 4 ). Then the screw cap ( 5 ) is screwed onto the clamping ring only to such an extent that the annular cross section between the cone of the screw cap and the sealing edge ( 3 ) of the clamping ring remains free for suction.

Zum Absaugen der Luft aus dem Beutel wird nun das Mundstück (7) auf die äußere Dichtfläche (8) der Schraubkappe (5) an­ gedrückt und die Luft über die Öffnungen (6) und (9) durch Lungenkraft oder eine adaptierbare Vakuumpumpe abgesaugt. Ist genügend Luft abgesaugt, wird die Beutelöffnung durch Drehen der des Mundstückes, unter Mitnahme der Schraubkappe bis zum Aufsitzen des Dichtkonus auf der Dichtkante (3) ge­ schlossen.To suck the air out of the bag, the mouthpiece ( 7 ) is now pressed onto the outer sealing surface ( 8 ) of the screw cap ( 5 ) and the air is sucked out through the openings ( 6 ) and ( 9 ) by lung force or an adaptable vacuum pump. If sufficient air is extracted, the bag opening is closed by turning the mouthpiece, taking the screw cap with it, until the sealing cone is seated on the sealing edge ( 3 ).

Vorteile dieser vorgeschlagenen Neuerung sind:
Einfache, sichere Funktion (die Dichtung erfordert geringe Anpreßkraft).The advantages of this proposed innovation are:
Simple, safe function (the seal requires low contact pressure).

Der Beutel kann ohne Zerstörung geöffnet und wieder ge­ schlossen werden.The bag can be opened and destroyed without being destroyed be closed.

Alle Teile sind preiswert, mit geringem Materialeinsatz herzustellen.All parts are inexpensive and use little material to manufacture.
