Description

Schraubkappe Zusatz zum Patent 1045 S34 Das Hauptpatent betrifft eine zum Verschließen von Flaschen und ähnlichen Behältern dienende Schraubkappe, deren längs einer Schwächungslinie abtrennbarer unterer Rand einen Behälterhalswulst sichernd untergreift, wobei diese Schwächungslinie unmittelbar in eine ausgeschnittene Griffzunge übergeht, unterhalb der sich ein schmaler Streifen befindet. Das Besondere liegt dabei darin, daß dieser schmale Streifen von dem unteren Schenkel der die Griffzunge bildenden Schnittlinie und einer daran anschließenden kurzen Schwächungslinie begrenzt ist, von deren Ende ein Einschnitt senkrecht zur unteren Kante des Kappenrandes führt. Screw cap addition to patent 1045 S34 The main patent relates to a screw cap used to close bottles and similar containers, whose lower edge, separable along a line of weakness, has a container neck bead securely engages below, with this line of weakness directly in a cut out Handle tongue goes over, below which there is a narrow strip. The special lies in the fact that this narrow strip of the lower leg of the Cut line forming the grip tongue and an adjoining short line of weakness is limited, from the end of which an incision perpendicular to the lower edge of the cap rim leads.

Es ist bereits eine Aufreißkappe bekannt, die eine sich direkt an die ausgeschnittene Griffzunge anschließende schräge Schnittlinie enthält, die bis an den unteren Kappenrand reicht. Die Festigkeit und Stabilität der Kappe wird also durch eine sehr lange Schnittlinie unterteilt, wodurch Störungen beim Verschließen und bei der Zuführung in die Verpackungsmaschinen auftreten können. Außerdem ist ein unbefugtes Öffnen durch einfaches Aufbiegen des unteren Randes möglich. A tear-open cap is already known that attaches itself directly to it the cut-out grip tongue contains subsequent oblique cutting line that extends up to reaches to the lower edge of the cap. So the strength and stability of the cap will be divided by a very long cutting line, which causes disruptions when closing and can occur when feeding into the packaging machines. Also is Unauthorized opening is possible by simply bending the lower edge.

Erfindungsgemäß schließt die kurze Schwächungslinie mit dem unteren Schenkel der die Griffzunge bildenden Schnittlinie einen Winkel ein, der mindestens 900 beträgt. Es hat sich nämlich gezeigt, daß beim Ziehen an der Griffzunge das Aufreißen des Werkstoffes der kurzen Schwächungslinie so lange leicht erfolgt, als diese etwa auf der Mantelfläche des Behälterwulstes verläuft. Dagegen muß der etwa senkrecht verlaufende Einschnitt, auf dessen Kombination mit der Schwächungslinie es ankommt, auf jeden Fall spätestens am unteren Ende des Wulstmantels erreicht sein, da an dieser Stelle der Widerstand des Werkstoffes gegen das Weiterreißen überraschend hoch ist. Aus diesem Grunde muß in jedem Falle der etwa senkrecht verlaufende Einschnitt von unten her wenigstens bis an die Mantelfläche des Behälterwulstes heranreichen. According to the invention, the short line of weakness closes with the lower one Leg of the cutting line forming the handle tongue an angle that is at least 900 is. It has been shown that when you pull the handle tongue the The material of the short line of weakness is easily torn as long as this runs approximately on the outer surface of the container bead. On the other hand, he has to perpendicular incision, on its combination with the weakening line it matters, in any case reached at the latest at the lower end of the bead jacket because at this point the resistance of the material against tearing further is surprisingly high. For this reason, the approximately vertical one must in each case Incision from below at least to the outer surface of the container bead reach out.

Diese Ausführungsform des Verschlusses ist vor allem dann günstiger als die in dem Hauptpatent erläuterte, wenn es sich um Flaschenverschlüsse sehr kleinen Durchmessers, aber ausreichender Höhe handelt, bei denen aus Platzmangel ein waagerechter Verlauf der Schwächungslinie fertigungsmäßig ungünstig ist.This embodiment of the closure is above all cheaper than that explained in the main patent when it comes to bottle caps small diameter, but sufficient height, where there is a lack of space a horizontal course of the weakening line is unfavorable in terms of production.

In der Zeichnung sind zwei Ausführungsformen des Schraubenkappenverschlusses nach der Er- findung in Seitenansicht dargestellt, wobei 1 den oberen Gewindeteil der Kappe, 2 die Griffzunge und 3 die oberhalb der Griffzunge ringsum verlaufende Schwächungslinie bezeichnet. Der senkrechte Einschnitt4 reicht bis zum Beginn des Ringwulstes des Behälters, z. B. einer Flasche, nach oben, und 5 ist die zwischen dem senkrecht verlaufenden Einschnitt 4 und dem unteren Ende der Schnittlinie der Griffzunge 2 liegende Schwächungslinie. Diese Schwächungslinie 5 verläuft in Fig. 1 senkrecht und in Fig. 2 schräg in der Reißrichtung, d. h., sie schließt mit dem unteren Schenkel 6 der die Griffzunge 2 bildenden Schnittlinie einen Winkel a ein, der mindestens 900 beträgt. In the drawing are two embodiments of the screw cap closure after the Finding shown in side view, where 1 is the upper threaded part the cap, 2 the handle tongue and 3 the one above the handle tongue all around Called the weakening line. The vertical incision4 extends to the beginning of the Annular bead of the container, e.g. B. a bottle, up, and 5 is the one between the perpendicular incision 4 and the lower end of the line of intersection of Grip tongue 2 lying line of weakness. This line of weakness 5 runs in Fig. 1 perpendicular and, in FIG. 2, obliquely in the direction of tear, i. i.e., it ends with the lower leg 6 of the cutting line forming the handle tongue 2 an angle a, which is at least 900.

Der Einschnitt 4 kann auch etwas schräg angeordnet sein und dann in der Reißrichtung verlaufen. The incision 4 can also be arranged somewhat obliquely and then run in the direction of tear.
