Abstract

Die Erfindung betrifft eine Kunststoffschraubkappe (1) zum Verschliessen von Behältern. Die Schraubkappe (1) be­ sitzt am offenen Ende eine Sicherung zum Anzeigen einer erfolgten unbefugten Öffnung. Die Sicherung greift im ver­ schlossenen Zustand mit einer nach innen vorspringenden, unterhalb des Kappengewindes (6) befindlichen Nase (9) hinter einen Wulst (16) am Behälterhals (14). Nach der Erfindung soll die Sicherung mit ihren Sollbruchstellen in die Schraubkappe (1) integriert sein, um sicherzustellen, dass nach dem erstmali­ gen Öffnen des Behalters (12) kein Teil der Schraubkappe (1) am Behälter verbleibt, der Behälter dennoch mit der Schraub­ kappe (1) erneut verschlossen werden kann. The invention relates to a plastic screw cap (1) for closing containers. The screw cap (1) there is a fuse at the open end for displaying one unauthorized opening. The fuse intervenes in ver closed state with an inwardly projecting, below the cap thread (6) located nose (9) behind a bead (16) on the container neck (14). According to the invention the fuse with its predetermined breaking points in the screw cap (1) be integrated to ensure that after the first time opening the container (12) no part of the screw cap (1) remains on the container, the container still with the screw cap (1) can be closed again.

Anschliessend an den Gewindeabschnitt (7) der Schraub­ kappe (1) weist deren Wand (8) als Sicherung mindestens einen bis zum unteren Kappenrand (22) reichenden Schlitz oder eine solche Schwächungszone (10) auf, die unterhalb der Nase (9) eine Sollbruch- oder Dehnstelle aufweist bzw. der Schlitz eine als Sollbruch- oder Dehnstelle dienende Überbrückung besitzt. Following the threaded section (7) the screw cap (1) has at least its wall (8) as a fuse a slot extending to the lower edge of the cap (22) or such a weakening zone (10), which is below the nose (9) has a predetermined breaking or expansion point or the slot a bridging serving as a predetermined breaking or stretching point owns.

Das Verschlusswerkzeug (18) ist als Glocke ausgebildet und besitzt eine nach innen vorspringende Abstützung (20, 20′) für den unteren Bereich der Schraubkappe (1). The closing tool (18) is designed as a bell and has an inwardly projecting support (20, 20 ') for the lower area of the screw cap (1).
