Abstract

Um Leckagen bei einer aus einem Außenbehälter (1) und einem Innenbehälter (2) gebildeten Zweikammerdruckpackung (27) mit konisch sich verjüngendem Mundstück (28) und gemeinsam umbördelten Innen- und Außenbehälter (1, 2) zu vermeiden, werden ein Verfahren zum Herstellen einer Zweikammerdruckpackung (27), eine damit herstellbare Zweikammerdruckpackung sowie darin verwendbare Vorrichtungen vorgeschlagen, bei bzw. mit denen der bereits in den Außenbehälter (1) eingebrachte Innenbehälter (2) mit Sollverformungszonen (25) versehen wird, die für ein gezielt ablaufendes Verknautschen des Innenbehälters (2) die Ausbildung von scharfen Kanten oder Falten reduzieren. Das Einbringen der Sollverformungszonen (25) erfolgt vorzugsweise über Einführen eines Werkzeugdorns (11) in den Innenbehälter (2) und Beaufschlagung des Innenbehälters (2) mit einer Druckdifferenz zwischen dessen Innenraum (7) und dem Treibmittelraum (8), so daß der bleibend deformierbare Innenbehälter (2) die Kontur des Werkzeugdoms (11) annehmend an letzteren gepreßt oder gesogen wird.

Figure 00000001
In order to avoid leaks in a two-chamber pressure pack (27) formed from an outer container (1) and an inner container (2) with a conically tapering mouthpiece (28) and jointly flanged inner and outer containers (1, 2), a method for producing a Two-chamber pressure pack (27), a two-chamber pressure pack that can be produced with it, and devices that can be used therein, are proposed, in or with which the inner container (2) that has already been introduced into the outer container (1) is provided with predetermined deformation zones (25), which are used for a deliberately running crumpling of the inner container ( 2) Reduce the formation of sharp edges or folds. The target deformation zones (25) are preferably introduced by inserting a tool mandrel (11) into the inner container (2) and applying a pressure difference between the interior space (7) and the propellant space (8) to the inner container (2), so that the permanently deformable one Inner container (2) assuming the contour of the tool dome (11) is pressed or sucked onto the latter.
