Abstract

The shape of the end cap matches the outer shape of the body (12) of a three-part tin-plate aerosol can (10) or folded end cap (14). Matching shaped fitments (19) are identically fixed to the integrated end cap of the one-piece aluminium can. The aluminium aerosol can has the same dimensions and functional properties as the end cap. The end cap has a shoulder corresponding to the flanged rim or fold (16) of the end cap.

Description

Die Erfindung betrifft eine einteilige Aerosoldose aus Aluminium mit integral angeformter Endkappe zur Fixierung eines Ventiltellers.The invention relates to a one-piece aerosol can made of aluminum with an integrally molded end cap for fixing a valve disk.

Die bekannten dreiteiligen Aerosoldosen weisen einen aus einem rechteckigen Blech über eine Längsschweissnaht zu einem Zylinder geformten Dosenkörper auf, dessen Enden mit einem Bodenteil sowie einer Endkappe zur Fixierung eines Ventiltellers versehen sind. Die flüssigkeits- und gasdichte Verbindung zwischen dem Dosenkörper und den beiden Endteilen erfolgt üblicherweise über einen sogenannten Doppelfalz mit zwischenliegender Dichtungsmasse. Statt eingefalzt können die beiden Endteile auch am Dosenkörper aufgebördelt sein. Um den an die Druckfestigkeit gefüllter Aerosoldosen gestellten Anforderungen zu genügen, ist das Bodenteil üblicherweise gegen das Doseninnere konvex gewölbt. Die Endkappe zur Befestigung des Ventiltellers ist ebenfalls den Druckverhältnissen angepasst und zudem zur Festlegung von Zubehörteilen wie beispielsweise Schutzkappen aus Kunststoff, Einrichtungen zum Schutz des Ventils oder spezieller Dispenservorrichtungen ausgestaltet.The known three-part aerosol cans have a can body formed from a rectangular sheet metal via a longitudinal weld seam to a cylinder, the ends of which are provided with a base part and an end cap for fixing a valve plate. The liquid- and gas-tight connection between the can body and the two end parts usually takes place via a so-called double rebate with an intermediate sealing compound. Instead of being crimped, the two end parts can also be crimped onto the can body. In order to meet the requirements placed on the pressure resistance of filled aerosol cans, the base part is usually convexly curved towards the inside of the can. The end cap for fastening the valve plate is also adapted to the pressure conditions and is also designed to fix accessories such as protective caps made of plastic, devices for protecting the valve or special dispensing devices.

Einteilige Aerosoldosen aus Aluminium zeichnen sich dadurch aus, dass Dosenkörper, Bodenteil und Endkappe durch Fliesspressen und Einziehen des Halses integral geformt sind.One-piece aerosol cans made of aluminum are characterized by the fact that the can body, base part and end cap are integrally formed by extrusion and pulling in the neck.

Der unterschiedliche Aufbau ein- und dreiteiliger Aerosoldosen sowie die diesen zugrundeliegenden unterschiedlichen Herstellungsverfahren haben in der Vergangenheit zu einer Entwicklung verschiedenartig geformter Endkappen der beiden Aerosoldosentypen geführt, mit dem Ergebnis, dass die Zubehörteile zwischen einteiligen Aerosoldosen aus Aluminium und dreiteiligen Aerosoldosen aus Weissblech trotz gleichem Dosendurchmesser nicht austauschbar sind.The different construction of one- and three-part aerosol cans and the different manufacturing processes on which they are based have in the past led to the development of differently shaped end caps of the two types of aerosol cans, with the result that the accessories between one-part aerosol cans made of aluminum and three-part aerosol cans made of tinplate did not, despite the same can diameter are interchangeable.

Angesichts dieser Gegebenheiten hat sich der Erfinder die Aufgabe gestellt, eine einteilige Aerosoldose aus Aluminium der eingangs genannten Art derart auszugestalten, dass die Zubehörteile zwischen einteiligen Aerosoldosen aus Aluminium und dreiteiligen Aerosoldosen aus Weissblech austauschbar sind, d.h. insbesondere die für die dreiteiligen Aerosoldosen aus Weissblech existierenden Zubehörteile auch bei den einteiligen Aerosoldosen aus Aluminium eingesetzt werden können.In view of these circumstances, the inventor has set himself the task of designing a one-piece aerosol can made of aluminum of the type mentioned at the beginning such that the accessories are interchangeable between one-piece aerosol cans made of aluminum and three-piece aerosol cans made of tinplate, i.e. In particular, the accessories available for the three-part aerosol cans made of tinplate can also be used for the one-piece aerosol cans made of aluminum.

Zur erfindungsgemässen Lösung der Aufgabe führt, dass die Endkappe der äusseren Kontur einer auf den Dosenkörper einer dreiteiligen Aerosoldose aus Weissblech aufgebördelten oder eingefalzten Endkappe derart angepasst ist, dass zur Festlegung an der Endkappe der dreiteiligen Aerosoldose aus Weissblech entsprechend gestaltete Zubehörteile identisch an den integral angeformten Endkappen der einteiligen Aerosoldose aus Aluminium festlegbar sind.In order to achieve the object according to the invention, the end cap of the outer contour of an end cap flanged or folded in on the can body of a three-part aerosol can made of tinplate is adapted in such a way that appropriately designed accessories are fixed identically to the integrally formed end caps on the end cap of the three-part aerosol can made of tinplate the one-piece aerosol can made of aluminum.

Bevorzugt weist die integral angeformte Endkappe der einteiligen Aerosoldose aus Aluminium die gleichen Dimensionen und funktionellen Eigenschaften auf wie die Endkappe der dreiteiligen Aerosoldose aus Weissblech. Insbesondere ist die integral angeformte Endkappe der einteiligen Aerosoldose aus Aluminium mit einer Schulter versehen, die dem Bördelrand oder Falz der Endkappe der dreiteiligen Aerosoldose aus Weissblech entspricht.The integrally molded end cap of the one-part aerosol can made of aluminum preferably has the same dimensions and functional properties as the end cap of the three-part aerosol can made of tinplate. In particular, the integrally molded end cap of the one-piece aerosol can made of aluminum is provided with a shoulder which corresponds to the flanged edge or fold of the end cap of the three-piece aerosol can made of tinplate.

Further advantages, features and details of the invention emerge from the following description of a preferred exemplary embodiment and with reference to the drawing; this shows schematically in
Fig. 1
a partially sectioned side view of an end cap crimped onto the can body of a three-part aerosol can made of tinplate;

Bei einer dreiteiligen Aerosoldose 10 aus Weissblech ist eine zur Aufnahme eines Ventiltellers vorgesehene Endkappe 14 über einen Doppelfalz 16 mit dem Dosenkörper 12 flüssigkeits- und gasdicht verbunden. Der Doppelfalz 16 dient beispielsweise als Halterung für eine entsprechend geformte Schutzkappe 19 aus Kunststoff.In the case of a three-part aerosol can 10 made of tinplate, an end cap 14 provided for receiving a valve plate is connected to the can body 12 in a liquid- and gas-tight manner via a double fold 16. The double fold 16 serves, for example, as a holder for a correspondingly shaped protective cap 19 made of plastic.

Fig. 2 zeigt die integral angeformte Endkappe einer einteiligen Aerosoldose aus Aluminium. Hierbei ist die äussere Kontur derjenigen der in Fig. 1 dargestellten Konstruktion nachgebildet. So entspricht beispielsweise der Doppelfalz 16 der dreiteiligen Aerosoldose aus Weissblech der bei der einteiligen Aerosoldose aus Aluminium entsprechend herausgeformten Schulter 26, die der Halterung einer zur Schutzkappe 19 identischen Schutzkappe 29 dient. Zur Aufnahme eines Ventiltellers ist am oberen Rand der integral angeformten Endkappe 20 in gleicher Weise wie bei der in Fig. 1 gezeigten Dose nach dem Stand der Technik ein Bördelrand 28 angeformt.Fig. 2 shows the integrally molded end cap of a one-piece aerosol can made of aluminum. Here, the outer contour of that of the construction shown in FIG. 1 is simulated. For example, the double fold 16 of the three-part aerosol can made of tinplate corresponds to the shoulder 26 which is correspondingly molded out in the case of the one-piece aerosol can made of aluminum and serves to hold a protective cap 29 which is identical to the protective cap 19. To accommodate a valve plate, a flanged edge 28 is formed on the upper edge of the integrally molded end cap 20 in the same way as in the prior art can shown in FIG. 1.
