Abstract

The closure component (4) is first positioned with a ring seal (15) on the container edge area (5). Then an axial pressure force (19) is applied on the closure area, using a pressure tool until an adequate sealing compression of the ring seal is achieved. An expanding tool is then brought into contact with a radial inner side (21) of the closure edge area an expansion tool is brought into contact. The two edge areas are expanded by the expansion tool until a firm locking is achieved. In a further step, a free end area (10) of the container edge and a free end area (13) of the closure edge are radially expanded into a cavity (16) of a safety ring (17). The ratio between the container nominal diameter and the effective axial length of the expansion tool is between 15 and 25.

Description

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruchs 1.The invention relates to a method according to the preamble of the claim 1.

Bei einem bekannten Verfahren dieser Art (CH-Patentschrift 642 316 A5 der Anmelderin) ergibt sich grundsätzlich ein sehr sicherer Verschluß des Verpackungsbehälters. Es wird ein Sicherungsring verwendet. Der bekannte Verpackungsbehälter ist jedoch noch nicht zur Verwendung für den Gefahrgutbereich gemäß UN geeignet. Dies gilt insbesondere für dünnflüssige Gefahrgüter.In a known method of this type (CH patent 642 316 A5 the applicant) results in a very secure closure of the packaging container. A circlip is used. The known packaging container is not yet for use for the hazardous goods area according to the UN. This applies in particular to low-viscosity dangerous goods.

Aus der DE 36 24 769 A1 ist es an sich bekannt, einen im Querschnitt im wesentlichen rechteckigen, schalenförmigen Behälter mit einem sich nach außen erstreckenden Umfangsflansch durch einen blattförmigen, ebenen Deckelzuschnitt aus einer Metallfolie zu verschließen. Dies geschieht mit einem in mehrere bewegliche Sektionen unterteilten Bördelrahmen. Mit den Sektionen wird der Rand des Deckelzuschnitts um den Umfangsflansch gebördelt. Dabei liegt ein Werkzeugoberteil auf dem Deckel abschnitt auf. Jede Sektion ist mit einem Gelenkviereck an einem stationären Halteteil angelenkt. Eine untere, hakenartige Bördelkante jeder Sektion wird bei einer axialen Verschließbewegung des Werkzeugs im Bogen von außen nach innen geführt und vollendet dabei die Randbördelung.From DE 36 24 769 A1 it is known per se, one in cross section essentially rectangular, bowl-shaped container with a outwardly extending circumferential flange through a leaf-shaped, to seal the flat lid blank from a metal foil. this happens with a crimp frame divided into several movable sections. With the sections, the edge of the lid blank is around the Flanged peripheral flange. There is an upper tool part on the Cover section open. Each section is with a quadrilateral at one stationary holding part articulated. A lower, hook-like flange each section is in an axial closing movement of the tool guided in a curve from the outside inwards and thereby completes the edging.

Aus der CH 391 570 A ist ein Verschließwerkzeug an sich bekannt, mit dem die oberen Randbereiche einer Öffnung im Deckel einer Stahltrommel einerseits und eines Verschließorgans andererseits ohne Verwendung eines Sicherungsrings dicht miteinander verbunden werden sollen. Dazu verlaufen diese Randbereiche ineinandergehakt zunächst achsparallel (Fig. 4). Die Randbereiche werden sodann durch radial antreibbare Backensegmente oberhalb und unterhalb einer axial mittleren, nicht zu expandierenden Ringzone unter einem Winkel nach außen expandiert (Fig. 5). Wenn das Verschließorgan einmal geöffnet ist, kann die Öffnung damit nicht wieder verschlossen werden.A closing tool is known per se from CH 391 570 A. which the upper edge areas of an opening in the lid of a steel drum on the one hand and a closing member on the other hand without using a Circlips should be tightly connected. To these edge areas are initially hooked together parallel to the axis (Fig. 4). The edge areas are then driven by radially Cheek segments above and below an axially middle one, not too expanding ring zone expanded at an angle to the outside (Fig. 5). Once the closure member is open, the Do not close the opening again.

Aus der US 4 820 100 A ist es an sich bekannt, einen kreiszylindrischen Rumpf durch eine Verschließeinheit einer Verschließmaschine (Fig. 1) mit einem Boden über einen Doppelfalz lose zu verschließen. Der Boden wird mit einer ersten Innenanrollung angeliefert und in eine Formausnehmung eines glockenförmigen Formwerkzeugs eingebracht. Sodann werden Formsegmente in der Formausnehmung radial nach außen bis in eine Betriebsendstellung gegenüber der ersten Innenanrollung bewegt (Fig. 4). Danach wird der Rumpf axial über den Boden gepreßt und durch das stationäre Formwerkzeug mit einer sich in die erste Innenanrollung des Bodens lose einrollenden zweiten Innenanrollung versehen (Fig. 5). Schließlich werden die Formsegmente radial nach innen zurückbewegt, damit die Dose aus der Maschine entnommen werden kann (Fig. 6). Der lose Doppelfalz wird erst in einer der Maschine nachgeschalteten Station (Fig.7) mit einem Rollenpaar dichtgepreßt.From US 4,820,100 A it is known per se to have a circular cylindrical shape Fuselage through a capping unit of a capping machine (Fig. 1) to loosely close with a bottom over a double fold. The floor is delivered with a first internal roll and in one Form recess of a bell-shaped mold introduced. Then are shaped segments in the mold recess radially outwards into an operating end position moves relative to the first internal roll (Fig. 4). Then the fuselage is pressed axially over the floor and through the stationary mold with one in the first internal curl of the floor with the second inner curl loosely rolling in (Fig. 5). Finally, the mold segments are moved radially inwards, so that the can can be removed from the machine (Fig. 6). The loose double fold is only connected in a machine Station (Fig. 7) tightly pressed with a pair of rollers.

Aus der GB-Patentschrift 357 558 ist es an sich bekannt, die Ränder einer Behälteröffnung und eines in die Behälteröffnung eingesetzten, tassenförmigen Deckels durch gemeinsame Expansion formschlüssig miteinander zu verbinden.

    • Fig. 1 zeigt einen Teil eines Verpackungsbehälters 1 mit einem Unterteil 2, dessen obere Öffnung 3 durch ein Verschlußelement 4 dicht verschlossen werden soll. Das Unterteil 2 und das Verschlußelement 4 bestehen aus Weißblech von z.B. 0,31 mm Dicke. Fig. 1 shows a part of a packaging container 1 with a lower part 2, whose upper opening 3 is sealed by a closure element 4 shall be. The lower part 2 and the closure element 4 are made made of tinplate from e.g. 0.31mm thickness.

    Ein erster Randbereich 5 des Unterteils 2 soll mit einem zweiten Randbereich 6 des Verschlußelements 4 dicht verbunden werden. Im Ausgangszustand besteht zwischen einer ersten Wand 7 des ersten Randbereichs 5 und einer zweiten Wand 8 des zweiten Randbereichs 6 ein Winkel 9 von z.B. 3 bis 5°. Der Winkel 9 erleichtert einerseits das Einsetzen des Verschlußelements 4 in die Öffnung 3, wie in Fig. 1 dargestellt, und ermöglicht andererseits das Ineinanderstapeln der Verschlußelemente 4 während Lagerung und Transport.A first edge area 5 of the lower part 2 should have a second edge area 6 of the closure element 4 are tightly connected. In the initial state exists between a first wall 7 of the first edge region 5 and a second wall 8 of the second edge region 6 an angle 9 of e.g. 3 to 5 °. The angle 9 facilitates the insertion of the one hand Closure element 4 in the opening 3, as shown in Fig. 1, and on the other hand enables the closure elements 4 to be stacked one inside the other during storage and transportation.

    Ein erster freier Endbereich 10 des ersten Randbereichs 5 ist als eine Außenanrollung ausgebildet. Ein freies Ende 11 der Außenanrollung liegt einem radial äußeren Abschnitt 12 der Außenanrollung gegenüber.A first free end region 10 of the first edge region 5 is as one External rolling trained. A free end 11 of the outside curl lies opposite a radially outer section 12 of the outer curl.

    An die zweite Wand 8 schließt sich oben ein zweiter freier Endbereich 13 des zweiten Randbereichs 6 an. Der zweite freie Endbereich 13 endet in einer Anrollung 14 und trägt eine Ringdichtung 15, die mit dem ersten freien Endbereich 10 abdichtend zusammenwirkt.A second free end region adjoins the second wall 8 at the top 13 of the second edge region 6. The second free end region 13 ends in a curl 14 and carries an annular seal 15 which with the first free end portion 10 cooperates sealingly.

    Das Verschlußelement 4 wird entweder von Hand oder automatisch so in der Öffnung 3 plaziert, wie dies Fig. 1 zeigt. Sodann wird mit einem ringförmigen Drückwerkzeug 18 eine axiale Druckkraft 19 bis zur ausreichenden Dichtkompression der Ringdichtung 15 auf einen oberen Rand des zweiten freien Endbereichs 13 ausgeübt. Dies hat zur Folge, daß die zweite Wand 8 noch etwas tiefer in die Öffnung 3 hineingedrückt wird, als dies in Fig. 1 zu sehen ist. Dabei drückt sich der erste freie Endbereich 10 entsprechend tiefer in die Ringdichtung 15 ein. The closure element 4 is either manually or automatically in the opening 3 placed, as shown in Fig. 1. Then with an annular Press tool 18 an axial pressure force 19 to the sufficient Sealing compression of the ring seal 15 on an upper edge of the second free end region 13. As a result, the second Wall 8 is pushed a little deeper into opening 3 than this can be seen in Fig. 1. The first free end area is pressed 10 correspondingly deeper into the ring seal 15.

    Sodann wird mit einer radial inneren Seite 21 des zweiten Randbereichs 6 ein Expandierwerkzeug 22 (s.auch Fig. 3) in Berührung gebracht. Dies geschieht dadurch, daß über den Umfang verteilte, im einzelnen nicht gezeichnete Segmente des Expandierwerkzeugs 22 radial nach außen bewegt werden. Dadurch werden der erste 5 und der zweite Randbereich 6 gemeinsam expandiert, bis eine formschlüssige Verriegelung erreicht ist. Während dieses Expandierens wird die axiale Druckkraft 19 aufrechterhalten, so daß sich der zweite freie Endbereich 13 in der in Fig. 2 ersichtlichen Weise zunehmend um den ersten freien Endbereich 10 herumlegt und damit die Abdichtung vervollständigt. In dem Endzustand gemäß Fig. 2 hat sich eine radial äußere Seite 23 der ersten Wand 7 gegen einen als Anschlag wirkenden, radial inneren Rand 24 eines freien Endes 40 der zweiten freien Endbereichs 13 gelegt.Then with a radially inner side 21 of the second edge region 6 brought an expanding tool 22 (see also FIG. 3) into contact. this happens in that distributed over the scope, not shown in detail Segments of the expanding tool 22 moved radially outward become. As a result, the first 5 and the second edge region 6 become common expands until a positive locking is achieved. While this expansion, the axial pressure force 19 is maintained, so that the second free end region 13 can be seen in FIG. 2 Way increasingly around the first free end region 10 and thus the sealing is completed. 2 in the final state a radially outer side 23 of the first wall 7 against one as a stop acting, radially inner edge 24 of a free end 40 of the second free end region 13 laid.

    Die formschlüssige Verriegelung ist gemäß Fig. 2 dadurch zustande gekommen, daß sich während der Expansion der erste freie Endbereich 10 in vollem Umfang über das Freie Ende 40 bewegt hat. The positive locking has come about according to FIG. that the first free end region 10 has moved in full over the free end 40.

    In Fig. 1 ist auch eine wirksame axiale Länge 38 des Expandierwerkzeugs 22 eingezeichnet.1 is also an effective axial length 38 of the expanding tool 22 shown.

    In allen Zeichnungsfiguren sind gleiche Teile mit gleichen Bezugszahlen versehen.In all drawing figures there are the same parts with the same reference numbers Mistake.

    Bei dem Ausführungsbeispiel nach Fig. 1 und 2 wird der zweite freie Endbereich 13 durch einen radial außerhalb angeordneten, ringförmigen Gegenhalter 39 abgestützt. Der Gegenhalter 39 ist in diesem Fall als unterer Fortsatz des Drückwerkzeugs 18 ausgebildet und bleibt stationär, solange mit dem Expandierwerkzeug 22 expandiert wird. Während dieses Expandierens rollt sich das freie Ende 40 des zweiten freien Endbereichs 13 zunehmend ein, bis es den ersten freien Endbereich 10 zur formschlüssigen Verriegelung axial fluchtend untergriffen hat. 1 and 2, the second becomes free End region 13 by a radially arranged, annular Bracket 39 supported. The counterholder 39 is in this case as lower extension of the pressing tool 18 is formed and remains stationary, as long as the expanding tool 22 is used for expansion. While this expanding, the free end 40 of the second free roll End region 13 increasingly until it is the first free end region 10 for axially positive locking.

    Dieser Zustand ist in Fig. 2 gezeigt. Dabei ist das Einrollen des freien Endes 40 so weit getrieben, daß das freie Ende 40 einerseits unten an dem freien Endbereich 10 und andererseits an der radial äußeren Seite 23 der ersten Wand 7 anliegt.This state is shown in Fig. 2. The curling up of the Free end 40 driven so far that the free end 40 on the one hand below on the free end region 10 and on the other hand on the radially outer Page 23 of the first wall 7.

    Wenn das Verschlußelement 4 von dem Unterteil 2 wieder abgenommen werden soll, kann die aus Fig. 2 ersichtliche formschlüssige Verriegelung durch das freie Ende 40 dadurch aufgehoben werden, daß zumindest ein den ersten freien Endbereich 10 axial fluchtend untergreifender Endabschnitt 41 des zweiten freien Endbereichs 13 von dem Rest des zweiten freien Endbereichs 13 abgetrennt wird. Dazu ist in dem zweiten freien Endbereich 13 eine um den gesamten Umfang umlaufende Ritzlinie 42 vorgesehen. Außerdem ist der Endabschnitt 41 mit einer Zunge 43 versehen, die mit einer Zange oder einem Schlüssel ergriffen und zum Ausgangspunkt des Abreißens des Endabschnitts 41 gemacht werden kann.When the closure element 4 can be removed from the lower part 2 again should, the positive locking shown in Fig. 2 can be canceled by the free end 40 in that at least one the first free end region 10 axially aligned under portion 41 of the second free end portion 13 from the rest of the second free end portion 13 is separated. This is free in the second End area 13 is provided with a scoring line 42 running around the entire circumference. In addition, the end section 41 is provided with a tongue 43, the gripped with pliers or a key and to the starting point of tearing off the end portion 41 can be made.

    Das Ausführungsbeispiel gemäß den Fig. 3 und 4 ähnelt dem der Fig. 1 und 2. In den Fig. 3 und 4 ist das freie Ende 40 mit einem umlaufenden unteren Fortsatz 44 versehen. Der untere Fortsatz 44 wird beim Expandieren durch einen längsgeteilten ringförmigen Gegenhalter 45 so abgestützt und geformt, daß er am Ende der Expansion bandagenartig an der radial äußeren Seite 23 der ersten Wand 7 anliegt. Dieser Endzustand ist in Fig. 4 dargestellt.The exemplary embodiment according to FIGS. 3 and 4 is similar to that of FIG. 1 and 2. In FIGS. 3 and 4, the free end 40 has a circumferential provided lower extension 44. The lower extension 44 will expand supported by a longitudinally divided annular counter-holder 45 and shaped so that at the end of the expansion it is bandaged on the radially outer side 23 of the first wall 7 abuts. This final state is shown in Fig. 4.

    Der längsgeteilte ringförmige Gegenhalter 45 schließt sich vorzugsweise gemäß Fig. 3 unten an den Gegenhalter 39 an und ist in den Richtungen eines Doppelpfeils 46 quer zu der Längsachse des Verpackungsbehälters 1 bewegbar.The longitudinally divided annular counter-holder 45 preferably closes 3 at the bottom of the counter-holder 39 and is in the directions a double arrow 46 movable transversely to the longitudinal axis of the packaging container 1.

    Die Ausführungsform nach Fig. 5 und 6 entspricht derjenigen nach Fig. 1 und 2. Allerdings ist während der Expansion gemäß Fig.6 an ein axial äußeres Ende 26 der zweiten Wand 8 eine sich über das äußere Ende 26 hinaus radial nach innen erstreckende Sicke 27 angeformt worden. Die Sicke 27 versteift den zweiten Randbereich 6 und gestattet dem zweiten freien Endbereich 13 eine optimale Formgestaltung innerhalb des durch das Drückwerkzeug 18 und den Gegenhalter 39 definierten Ringraums.5 and 6 corresponds to that 1 and 2. However during the expansion according to FIG. 6 to an axially outer end 26 the second wall 8 a radially beyond the outer end 26 inwardly extending bead 27 has been formed. The bead 27 stiffened the second edge area 6 and allows the second free end area 13 an optimal design within the by the pressing tool 18 and the counter holder 39 defined annulus.

    Fig. 7 verdeutlicht, wie die einzelnen Segmente des Expandierwerkzeugs 22 mit einer radiaTen Nut 28 auf einem radialen Führungsring 29 des Drückwerkzeugs 18 geführt sind. So können sich die Segmente des Expandierwerkzeugs 22 in den Richtungen eines Doppelpfeils 30 in radialer Richtung zum Expandieren und wieder zurück in ihre Ruhestellung bewegen. Diese Bewegung erfolgt durch einen mittigen Konus 31, dessen Außenfläche mit einer komplementären Schrägfläche 32 jedes Segments des Expandierwerkzeugs 22 zusammenwirkt. Der Konus 31 wird parallel zur Längsachse des Verackungsbehälters 1 in den Richtungen eines Doppelpfeils 34 in im einzelnen nicht dargestellter Weise angetrieben. Die Werkzeuge 18 und 22 sowie der Konus 31 können parallel zur Längsachse des Verpackungsbehälters 1 in den Richtungen eines Doppelpfeils 35 als Einheit bewegt werden.Fig. 7 illustrates how the individual segments of the expanding tool 22 with a radial groove 28 on a radial guide ring 29 of the Pressing tool 18 are guided. So the segments of the expanding tool 22 in the directions of a double arrow 30 in the radial Direction to expand and move back to its rest position. This movement takes place through a central cone 31, the outer surface of which with a complementary sloping surface 32 of each segment of the Expanding tool 22 cooperates. The cone 31 is parallel to Longitudinal axis of the packaging container 1 in the directions a double arrow 34 driven in a manner not shown in detail. The tools 18 and 22 and the cone 31 can be parallel to the longitudinal axis of the packaging container 1 in the directions of a double arrow 35 as a unit be moved.
