Description

Die Erfindung betrifft einen Behälter für Flüssigkeiten oder flüssigkeitsähnliche Massen, insbesondere Farbeimer, mit einer auf die Behälterwandung aufgebrachten Schutzschicht, die von der Wandung ablösbar ist.The invention relates to a container for liquids or liquid-like masses, in particular paint buckets, with a protective layer applied to the container wall, which can be detached from the wall.

Solche zumeist in Eimer- oder Kanisterform ausgeführten Behälter dienen als Verkaufsverpackungen für Farben, Lösungsmittel u.dgl. Gemäß der Verpackungsverordnung ist ein Käufer dazu befugt, die Verkaufsverpackung nach Gebrauch des jeweiligen Inhalts an die Verkaufsstelle zur Wiederverwendung, Wiederverwertung oder Entsorgung zurückzugeben.Such containers, usually in the form of buckets or canisters, serve as sales packaging for paints, solvents and the like. According to the packaging ordinance, a buyer is authorized to return the sales packaging to the point of sale after use of the respective content for reuse, recycling or disposal.

Die Behälter sind jedoch bei der Rückgabe i.a. durch Restmengen des vormaligen Inhalts verschmutzt, so daß die Behälter vor einer Wiederverwendung gereinigt werden müssen oder eine Wiederverwendung des Behälters unter Umständen gar nicht möglich ist. Es ist daher ein Behälter der eingangs genannten Art bekannt (DE 40 23 908 A1), bei dem eine durch den bestimmungsgemäßen Inhalt nicht lösbare, aber mit einem wässrigen Waschmittel lösbare Kunststoffschicht als Überzug vorgesehen ist. Solche mit wässrigen Waschmitteln lösbare Kunststoffe eignen sich für gewisse Getränke, jedoch nicht für die Aufbewahrung von Farben oder Lösungsmitteln. Die nach Gebrauch abgewaschene Kunststoffschicht muß vor einer Wiederverwendung des Behälters auch stets erneuert werden, was aufwendig ist.However, when the containers are returned they are generally contaminated by residual amounts of the previous contents, so that the containers have to be cleaned before reuse or the container may not be reusable under certain circumstances. A container of the type mentioned at the outset is therefore known (DE 40 23 908 A1), in which a plastic layer is provided as a coating which cannot be removed due to the intended content but can be removed with an aqueous detergent. Such plastics that are soluble with aqueous detergents are suitable for certain beverages, but not for storage of paints or solvents. The plastic layer washed off after use must always be renewed before reusing the container, which is expensive.

Bekannt ist es auch, Behälter mit auswechselbaren Foliensäcken o.dgl. zu versehen (DE 34 39 442 A1 oder DE 40 33 236 A1). Solche Lösungen sind aber für Behälter zur Aufnahme von Farben oder Lösungsmitteln ungeeignet.It is also known to have containers with interchangeable film bags or the like. to be provided (DE 34 39 442 A1 or DE 40 33 236 A1). However, such solutions are unsuitable for containers for holding paints or solvents.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Behälter der eingangs genannten Art zu schaffen, bei dem eine Erneuerung einer Schutzschicht bei Wiedergebrauch überflüssig wird. Die Aufgabe wird gelöst durch einen Behälter der eingangs genannten Art mit mindestens einer weiteren, insbesondere aber mit mehreren, unter Zwischenfügung jeweils einer Trennschicht auf die Behälterwandung aufgebrachten Schutzschichten, die ausgehend von mindestens einer Ablösestelle von der Wandung ablösbar sind.The invention is therefore based on the object of providing a container of the type mentioned at the outset in which a renewal of a protective layer becomes unnecessary when it is used again. The object is achieved by a container of the type mentioned at the outset with at least one further, but in particular with a plurality of protective layers applied to the container wall with the interposition of a separating layer in each case and which can be detached from the wall starting from at least one detachment point.

Bei der Rückgabe zur Verkaufsstelle bzw. zum Abfüller können die im Behälter befindlichen Reste und Verschmutzungen durch einfaches Abziehen der mit dem Behälterinhalt in Berührung gewesenen Schutzschicht von der Ablösestelle her zusammen mit der Schutzschicht entfernt werden, womit der Behälter "gereinigt" ist und wiederverwendet werden kann. Der Behälter kann mehrere Male wiederverwendet werden. Bei nichtbeschädigtem Behälter kann nach Verbrauch sämtlicher Schutzschichten ein erneutes Aufbringen von mehreren Schutzschichten erfolgen. Der Behälter ist dann so lange wiederverwendbar, bis Verschleißerscheinungen seinen weiteren Einsatz nicht mehr erlauben.When returning to the point of sale or to the bottler, the residues and soiling in the container can be removed by simply pulling off the protective layer that has come into contact with the contents of the container, together with the protective layer, which means that the container is "cleaned" and can be reused . The container can be reused several times. If the container is not damaged, all protective layers can be applied again after several protective layers have been used. The container can then be reused until signs of wear no longer permit its further use.

Vorteilhafterweise verläuft die mindestens eine Ablösestelle für die Schutzschicht rund um den Rand einer Öffnung des Behälters. Durch das Anordnen der Ablösestelle am Rand der Behälteröffnung ist diese bei verschlossenem Behälter von dessen Verschluß mit abgedeckt und geschützt. Auch bei geöffnetem Behälter ist die Ablösestelle am Öffnungsrand nicht direkt zugänglich und somit vor nichtbeabsichtigtem Ablösen gesichert.The at least one detachment point for the protective layer advantageously runs around the edge of an opening in the container. By arranging the detachment point on the edge of the container opening, this is covered and protected by the closure when the container is closed. Even when the container is open the detachment point at the edge of the opening is not directly accessible and thus secured against unintentional detachment.

In vorteilhafter Ausgestaltung nach dem Unteranspruch 3 erstreckt sich die Schutzschicht sowohl über die Innenwand als auch die Außenwand des Behälters. Dadurch wird sichergestellt, daß beim Ablösen der Schutzschicht nicht nur im Inneren des Behälters verbliebene Reste entfernt werden, sondern auch Verschmutzungen an der Außenseite des Behälters.In an advantageous embodiment according to subclaim 3, the protective layer extends both over the inner wall and the outer wall of the container. This ensures that when the protective layer is removed, not only residues remaining inside the container are removed, but also dirt on the outside of the container.

Die einzelnen Schutzschichten des Behälters bestehen vorteilhafter Weise aus Kunststoff, wobei die jeweilige Trennschicht ein Trennmittel, insbesondere Talkum, Silikon oder Mineralöl, beinhaltet. Es können auch Schutzschichten aus Wachs vorgesehen werden, die thermisch oder auch mechanisch gelöst werden können.The individual protective layers of the container are advantageously made of plastic, the respective separating layer containing a separating agent, in particular talc, silicone or mineral oil. Protective layers made of wax can also be provided, which can be released thermally or mechanically.

Die Schutzschichten können nach Aufbringen einer Trennschicht auf die Behälterwandung bzw. auf eine schon aufgebrachte Schutzschicht durch einfaches Aufsprühen, durch Tauchen oder durch Tiefziehen aufgebracht werden.After applying a separating layer to the container wall or to an already applied protective layer, the protective layers can be applied by simple spraying, by dipping or by deep drawing.

Fig. 1 zeigt in schematischer Schnittdarstellung einen erfindungsgemäßen Behälter (10) in Eimerform mit einer Behälterwandung (1), welche rund um eine nach oben gebende Öffnung des Behälters als Deckelwulst (2) ausgebildet ist. Der Behälter (10) verfügt über mehrere sowohl auf der Innenseite als auch der Außenseite der Behälterwandung (1) auf diese mehrlagig angebrachte Schutzschichen (5).Fig. 1 shows a schematic sectional view of a container (10) according to the invention in the form of a bucket with a container wall (1) which is designed as a cover bead (2) around an upward opening of the container. The container (10) has a plurality of protective layers (5), which are attached to this on both the inside and the outside of the container wall (1).

Zur Verdeutlichung der Anordnung der Schutzschichten (5) auf der Behälterwandung (1) zeigt Fig. 2 in vergrößerter Darstellung einen in der Fig. 1 eingezeichneten und mit (II) bezeichneten Abschnitt aus dem Bodenrandbereich des eimerförmigen Behälters (10). Unter Zwischenfügung einer Trennschicht (4a) ist auf die Behälterwandung (1) sowohl auf der Innenseite als auch der Außenseite des Behälters eng anliegend eine erste Schutzschicht (5a) aufgebracht. Diese erste Schutzschicht (5a) wiederum ist durch eine Trennschicht (4b) von einer weiteren Schutzschicht (5b) getrennt. Diese Schichtung wiederholt sich mit einer weiteren Trennschicht (4c) und weiteren Schutzschicht (5c) noch einmal, so daß die Behälterwandung (1) nach beiden Seiten über eine dreifach alternierende Folge aus Trennschichten (4) und Schutz schichten (5) verfügt. Die einzelnen Schutzschichten (5a, 5b, 5c) sind bei Bedarf zum Entfernen von Verschmutzungen des Behälters durch Abziehen vom Behälter (10) an einem Stück ablösbar.To clarify the arrangement of the protective layers (5) on the container wall (1), FIG. 2 shows, in an enlarged representation, a section from the bottom edge region of the bucket-shaped container (10), which is shown in FIG. 1 and is labeled (II). With the interposition of a separating layer (4a), a first protective layer (5a) is applied tightly to the container wall (1) both on the inside and the outside of the container. This first protective layer (5a) is in turn separated from a further protective layer (5b) by a separating layer (4b). This stratification is repeated with a further separating layer (4c) and a further protective layer (5c) so that the container wall (1) has a triple alternating sequence of separating layers (4) and protective layers (5) on both sides. If necessary, the individual protective layers (5a, 5b, 5c) can be removed in one piece by removing them from the container (10) by removing them from the container.

Dazu dient eine Ablösestelle (6) am unteren Rand der Deckelwulst (2), die in Fig. 3 als Vergrößerung des Ausschnittes (III) der Fig. 1 dargestellt ist. Durch Ablösen der entsprechend äußersten Schutzschicht an der Ablösestelle (6) kann die Schutzschicht gegriffen und durch Abziehen vom Behälter entfernt werden. Die Ablösestelle (6) ist am unteren Rand der Deckelwulst (2) so angeordnet, daß ein unbeabsichtigtes Ablösen der Schutzschichten (5) nicht möglich ist, die Ablösestelle (6) jedoch im Bedarfsfall gut zugänglich ist. Die Ablösestellen (6) stellen dabei eine Verbindung zwischen den Schutzschichten der Innenseite und den Schutzschichten der Außenseite des Behälters dar.A detachment point (6) on the lower edge of the cover bead (2) serves this purpose, which is shown in FIG. 3 as an enlargement of the detail (III) of FIG. 1. The protective layer can be gripped by removing the corresponding outermost protective layer at the detachment point (6) and removed from the container by pulling it off will. The detachment point (6) is arranged on the lower edge of the cover bead (2) so that unintentional detachment of the protective layers (5) is not possible, but the detachment point (6) is easily accessible if necessary. The detachment points (6) represent a connection between the protective layers on the inside and the protective layers on the outside of the container.
