Abstract

The bottle cap and the tear-off strip associated therewith are in each case manufactured from a web (13, 24) of plastic sheet which is prestretched in the longitudinal direction. A special method ensures that, even in the case of the tear-off strip (19), the prestretching direction runs in the longitudinal direction and thus in the circumferential direction of the cap and that the tear-off strips can be produced without waste from a sheet web (24) or blank web prestretched in the longitudinal direction. <IMAGE>

Description

Die Erfindung betrifft eine Flaschenkapsel, aus einem vor­gereckten Kunststoff-Folienzuschnitt gewickelt, mit einem auf der Innenseite der Kapsel befestigten, an einer Stelle über den Kapselzuschnitt vorstehenden Aufreißband, sowie ein Verfahren zu ihrer Herstellung.The invention relates to a bottle capsule, wound from a pre-stretched plastic film blank, with a tear tape attached to the inside of the capsule and protruding from the capsule blank at one point, and a method for its production.

Aus vorgereckter Kunststoff-Folie gefertigte Flaschen­kapseln, die sich auf Flaschenköpfe durch Wärmeeinwirkung aufschrumpfen lassen, sind bekannt. Bisher ist es üblich, die Kapselzuschnitte aus einem quer zu ihrer Längsrichtung vorgereckten Kunststoff-Folienband herzustellen, dessen Breite der Wickellänge des Kapselzuschnittes entspricht. Von dem in Querrichtung vorgereckten Folienband konnten dabei die Kapselzuschnitte einfach als Abschnitte mit einer der Kapselhöhe entsprechenden Länge abgeschnitten werden. Für die Aufreißbänder konnten von gleichen Folien­band schmale Querstreifen abgetrennt und anschließend auf der Innenseite des Kapselzuschnittes befestigt werden. Der einfachen Fertigung der Flaschenkapseln aus quer zu ihrer Längsrichtung vorgereckter Kunststoff-Folie steht aber der Nachteil entgegen, daß quer zu ihrer Längsrichtung vorge­reckte Kunststoff-Folie teurer in der Herstellung ist als in der Längsrichtung vorgereckte Kunststoff-Folie.Bottle caps made from pre-stretched plastic film, which can be shrunk onto bottle heads by the action of heat, are known. So far, it has been customary to produce the capsule blanks from a plastic film strip which is stretched transversely to their longitudinal direction and whose width corresponds to the winding length of the capsule blank. The capsule blanks could simply be cut off from the film strip stretched in the transverse direction as sections with a length corresponding to the capsule height. For the tear tapes, narrow transverse strips could be separated from the same foil tape and then opened be attached to the inside of the capsule blank. The simple manufacture of the bottle caps from plastic film stretched transversely to their longitudinal direction stands in the way of the disadvantage that plastic film pre-stretched transversely to their longitudinal direction is more expensive to produce than plastic film pre-stretched in the longitudinal direction.

Der Erfindung liegt die Aufgabe zugrunde, eine Flaschen­kapsel aus einem in Längsrichtung vorgereckten, preiswer­teren Kunststoff-Folienband mit einen passenden Aufreiß­band zu schaffen und ein Verfahren für eine preisgünstige Fertigung solcher Flaschenkapseln aus dem in Längsrichtung vorgereckten Kunststoff-Folienband zu entwickeln.The invention has for its object to provide a bottle cap from a longitudinally stretched, cheaper plastic film tape with a suitable tear tape and to develop a method for inexpensive production of such bottle capsules from the longitudinally stretched plastic film tape.

Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, daß bei der Flaschenkapsel sowohl der Kunststoff-Folien­zuschnitt für die Kapsel als auch das Aufreißband aus einer in ihrer Längsrichtung vorgereckten Folienbahn ge­fertigt ist. Erfindungsgemäß lassen sich solche Flaschen­kapseln nach einem Verfahren preisgüngstig herstellen, das dadurch gekennzeichnet ist, daß ein in Längsrichtung vor­gerecktes, einseitig mit einem siegel-oder klebefähigen Medium beschichtetes Kunststoff-Folienband durch Quer­schnitte, die in Abständen geführt werden, welche min­destens der gewünschten Länge des mit dem Folienzuschnitt in Verbindung kommenden größeren Teiles des Aufreißbandes entsprechen, zunächst in einzelne Abschnitte getrennt wird, daß die einzelnen Folienbahnabschnitte entlang ihrer Bahnlängsränder mit geringfügiger Überlappung zu einem neuen Band aneinandergeklebt werden, aus welchem wiederum durch Querschnitte in ihrer Längsrichtung vorgereckte Auf­reißbänder gewonnen werden, und daß abschließend die Auf­reißbändchen auf die aus einem anderen, ebenfalls in Längsrichtung vorgereckten Kunststoff-Folienband geschnit­tenen oder gestanzten Kapselzuschnitte auf die Vorreck­richtung ausgerichtet aufgeklebt werden.The object is achieved according to the invention in that in the bottle capsule both the plastic film cut for the capsule and the tear strip are made from a film web stretched in its longitudinal direction. According to the invention, such bottle capsules can be produced inexpensively by a process which is characterized in that a plastic film strip pre-stretched in the longitudinal direction and coated on one side with a sealable or adhesive medium by cross-sections which are guided at intervals which are at least the desired length of the correspond to the film cut in connection of the larger part of the tear tape coming into contact, first being separated into individual sections, that the individual film web sections are glued together along their longitudinal edges with a slight overlap to form a new tape, from which in turn tear strips are stretched in cross-sections in their longitudinal direction, and that finally the tear tapes on the from another, also in Longitudinally pre-stretched plastic film tape cut or punched capsule blanks are glued aligned to the direction of stretching.

Das Verfahren gemäß der Erfindung läßt sich einrichtungs­mäßig sicher ausführen, wobei zweckmäßig in einer Vorrich­tung das aus sich geringfügig überlappenden Folienbahn­abschnitten gebildete Band quer zu dem ursprünglichen, in Längsrichtung vorgereckten Kunststoff-Folienband und quer auf das zur Bildung der Kapselzuschnitte dienende, in Längsrichtung vorgereckte Kunststoff-Folienband zu bewegt wird.The method according to the invention can be carried out safely in terms of equipment, the tape formed from slightly overlapping film web sections expediently in a device transversely to the original plastic film tape stretched in the longitudinal direction and transversely to the plastic film stretching in the longitudinal direction used to form the capsule blanks. Foil tape is moved too.

Mit dem Verfahren gemäß der Erfindung lassen sich Flaschenkapseln, die gemeinsam mit ihrem Aufreißband schrumpfen können, aus in Längsrichtung vorgereckten Kunststoff-Folienbändern ohne großen Bandabfall fertigen. Dabei kann das zur Bildung der Aufreißbänder dienende, in Längsrichtung vorgereckte Kunststoff-Folienband auch ein Randstreifen des längsgereckten Kunststoff-Folienbandes sein, aus welchem die Kapselzuschnitte gefertigt werden. Dieser Randstreifen wird zunächst vom handelsüblichen vor­gereckten Kunststoff-Folienband abgetrennt. Es kann auch ein beim Bedrucken der Folie angefallener Abfallstreifen sein. Dabei spielt es keine Rolle, wie breit der Rand­streifen ist, weil erfindungsgemäß die Abschnitte, in wel­che der Randstreifen zerlegt wird, entlang ihren Längs­rändern zu einem neuen Band zusammengeklebt werden, von welchem erst die Aufreißbänder abgeschnitten werden und in welchem es keine Rolle spielt, wie groß die einzelnen Abschnitte sind, aus welchen dieses Band zusammengesetzt ist.With the method according to the invention, bottle capsules, which can shrink together with their tear-open tape, can be produced from plastic film tapes that have been stretched in the longitudinal direction without large tape waste. The plastic film tape which is pre-stretched in the longitudinal direction and serves to form the tear tapes can also be an edge strip of the longitudinally stretched plastic film tape, from which the capsule blanks are produced. This edge strip is first separated from the commercially available pre-stretched plastic film tape. It can also be a waste strip that is produced when the film is printed. It does not matter how wide the edge strip is, because according to the invention the sections into which the edge strip is divided are glued together along their longitudinal edges to form a new strip, from which the tear strips are first cut off and in which does not matter how big the individual sections are, of which this volume is composed.

Nachfolgend wird der Erfindungsgegenstand anhand der bei­liegenden Zeichnung näher erläutert.The subject matter of the invention is explained in more detail below with reference to the accompanying drawing.

Fig. 1 zeigt eine Flaschenkapsel 10, deren Kapselkörper 11 aus einem in Fig. 2 bezeichneten Kapselzuschnitt 12 ge­wickelt ist, der auf einem in seiner Längsrichtung vorge­reckten Kunststoff-Folienband 13 so ausgerichtet ist, daß die Vorreckrichtung in Umfangsrichtung des Kapselkörpers 11 verläuft, der Kapselkörper 11 also in seiner Umfangs­richtung schrumpft. Der Kapselkörper 11 ist auf seiner Oberseite 14 in bekannter Weise durch Einfalten eines in Fig. 2 bezeichneten Randabschnittes 15 des Kapselzuschnit­tels 12 geschlossen. Ansonsten erhält der Kopfteil 17 der Kapsel durch eine Prägung nach dem Wickeln des Kapselzu­ schnittes 12 ein einem Flaschenkopf angepaßtes Aussehen, insbesondere durch das Anbringen einer Umfangssicke 16 und einer oberen Abschlußschulter 18. Im Kopfbereich ist die Flaschenkapsel 10 mit einem in Umfangsrichtung verlaufen­den Aufreißband 19 versehen, das ebenfalls aus einer vorgereckten Kunststoff-Folie gefertigt ist, wobei die Vorreckrichtung in der Längsrichtung des Aufreißbandes verlaufen muß, damit das Aufreißband 19 zusammen mit der Flaschenkapsel 11 in der gleichen Richtung schrumpfen kann. Das Aufreißband 19 wird auf den Kapselzuschnitt 12 so aufgeklebt, daß es mit einem Griffende 20 über einen der beiden Seitenränder 21 des Kapselzuschnittes 12 hinausragt und dadurch auf der fertiggewickelten Flaschen­kapsel 10 freiliegt.Fig. 1 shows a bottle cap 10, the capsule body 11 is wound from a capsule blank 12 designated in Fig. 2, which is aligned on a stretched in its longitudinal direction plastic film tape 13 so that the stretching direction extends in the circumferential direction of the capsule body 11, the capsule body 11 thus shrinks in its circumferential direction. The capsule body 11 is closed on its upper side 14 in a known manner by folding in an edge section 15 of the capsule blank 12 which is designated in FIG. 2. Otherwise, the head portion 17 of the capsule is embossed after the capsule is wrapped Cut 12 a look adapted to a bottle head, in particular by attaching a peripheral bead 16 and an upper end shoulder 18. In the head region, the bottle cap 10 is provided with a tear tape 19 running in the circumferential direction, which is also made of a pre-stretched plastic film, the stretching direction must run in the longitudinal direction of the tear tape so that the tear tape 19 can shrink together with the bottle cap 11 in the same direction. The tear tape 19 is glued to the capsule blank 12 in such a way that it projects with one end of the handle 20 over one of the two side edges 21 of the capsule blank 12 and is thereby exposed on the finished wound bottle capsule 10.

Wie Fig. 2 zeigt, werden die Kapselzuschnitte 12 aus dem in seiner Längsrichtung vorgereckten Kunststoff-Folienband 13 so ausgestanzt, daß die die Umfangsränder der fertigen Flaschenkapsel 10 bildenden Längsränder 22 und 23 des Kapselzuschnittes 12 ebenfalls in der Längsrichtung des Folienbandes 13 verlaufen. Die Aufreißbänder 19 werden auf die Folienzuschnitte 12 erst nach ihrem Ausstanzen aus dem Folienband 13 aufgeklebt, das auf der betreffenden Seite, die später die Innenseite der Flaschenkapsel 10 bildet, im allgemeinen auf ihrer ganzen Fläche mit einer erst durch eine nachträgliche Wärmeeinwirkung aktivierbaren Kleb­stoffschicht versehen ist. Das in Fig. 2 dargestellte Folienband 13 stellt ein auf die Höhe der Kapselzu­schnitte 12 angepaßtes handelsübliches vorgerecktes Folienband dar, wobei die Anpassung durch das Antrennen eines Randstreifens 24 erfolgt ist. Der Randstreifen 24 stellt aber keinen Abfall dar. Aus ihm können die Aufreiß­bänder nach einem Verfahren gefertigt werden, das nachfol­ gend in Verbindung mit der in Fig. 3 schematisch darge­stellten Einrichtung erläutert wird.As shown in FIG. 2, the capsule blanks 12 are punched out of the plastic film strip 13 stretched in its longitudinal direction so that the longitudinal edges 22 and 23 of the capsule blank 12 forming the peripheral edges of the finished bottle capsule 10 also run in the longitudinal direction of the film strip 13. The tear tapes 19 are glued to the film blanks 12 only after they have been punched out of the film strip 13, which on the relevant side, which later forms the inside of the bottle capsule 10, is generally provided over its entire surface with an adhesive layer which can only be activated by subsequent heat . The film strip 13 shown in FIG. 2 represents a commercially available pre-stretched film strip adapted to the height of the capsule blanks 12, the adaptation being carried out by severing an edge strip 24. The edge strip 24, however, does not represent waste. The tear tapes can be produced from it by a method that follows will be explained in connection with the device shown schematically in Fig. 3.

In Fig. 3 ist die in ihrer Längsrichtung vorgereckte und bereits auf die Höhe der Flaschenzuschnitte 12 zugeschnit­tene Folienbahn 13 dargestellt, die in Richtung des einge­tragenen Pfeiles 25 unter einer nur schematisch darge­stellten Bearbeitungsstation 26 hindurchgeführt wird, in welcher die Flaschenzuschnitte 12 aus dem Folienband 13 ausgestanzt und gleichzeitig mit den Aufreißbändern 19 versehen werden. Der abgetrennte Randstreifen 24 der längsgereckten Folienbahn ist auf eine Vorratsrolle 27 ge­wickelt und wird von dieser mittels einer Vorschubwalze 28 schrittweise abgezogen und einem Querschneidmesser 29 zu­geführt, mit welchem von dem Folienband 24 gleiche Ab­schnitte abgetrennt werden, deren Länge mindestens der ge­wünschten Länge des Aufreißbandes 19 entspricht, mit wel­cher das Aufreißband 19 in Verbindung mit dem Flaschenzu­schnitt 12 gebracht werden soll. Die abgetrennten Folien­abschnitte 30 werden anschließend in Richtung des einge­tragenen Pfeiles 31 und damit quer zur Vorschubrichtung des Folienbandes 24 bewegt, dessen Vorschubrichtung durch einen Pfeil 32 gekennzeichnet ist. Die einzelnen Abschnit­te 30 werden mit geringfügiger Überlappung 33 mittels einer Klebvorrichtung 34 zu einem neuen Band 35 zusammen­gehängt, in welchem die Vorreckrichtung quer zur Längs­richtung dieses neuen Bandes 35 verläuft. Gleichzeitig wird von einer Vorratsrolle 36 ein schmales Aluminiumband 37 für Griffenden der Aufreißbänder 19 über eine Umlenk­vorrichtung 38 dem neuen Band 35 zugeführt und entlang seines einen Randes mit ihm verbunden. Das neue Band 35 wird mittels einer Vorschubwalze 39 der Vorrichtung 26 zu­geführt, in welchem von dem neuen Band 35 durch ein nicht dargestelltes Querschneidmesser die einzelnen Aufreiß­bänder 19 abgetrennt und anschließend sofort auf die Kapselzuschnitte 12 aufgebracht werden.3 shows the film web 13 which has been stretched in its longitudinal direction and already cut to the height of the bottle blanks 12 and which is guided in the direction of the arrow 25 below a processing station 26 which is shown only schematically and in which the bottle blanks 12 are punched out of the film strip 13 and at the same time be provided with the tear tapes 19. The severed edge strip 24 of the longitudinally stretched film web is wound onto a supply roll 27 and is gradually pulled off from it by means of a feed roller 28 and fed to a cross-cutting knife 29 with which the same sections are separated from the film band 24, the length of which corresponds at least to the desired length of the tear-off band 19 , with which the tear tape 19 is to be brought into connection with the bottle blank 12. The separated film sections 30 are then moved in the direction of the arrow 31 and thus transversely to the direction of advance of the film strip 24, the direction of which is indicated by an arrow 32. The individual sections 30 are connected with a slight overlap 33 by means of an adhesive device 34 to form a new band 35, in which the direction of stretching extends transversely to the longitudinal direction of this new band 35. At the same time, a narrow aluminum band 37 for the grip ends of the tear strips 19 is fed from a supply roll 36 to the new band 35 via a deflection device 38 and connected to it along its one edge. The new belt 35 is fed to the device 26 by means of a feed roller 39, in which the new belt 35 does not pass through a device Cross cutting knife shown, the individual tear strips 19 separated and then immediately applied to the capsule blanks 12.
