Description

DEUTSCHESGERMAN

Lose einsetzbare oder auswechselbare Innenauskleidungen für Verpackungsgefäße werden bisher in Beutel- oder Sackform vorgearbeitet und danach in die Gefäße eingeführt. Die vornehmlich aus verschweißbaren Kunststoffen bestehenden Innenauskleidungen werden derart zu beuteiförmigen Behältnissen geformt, indem die flach aufeinander!legenden Wandungen geradlinig verbunden werden, so daß die Bodennaht quer verläuft. Beim Einfuhren des Füllgutes muß sich der Beutel bei runden oder eckigen Gefäßen jeweils in der Bodennähe so ausdehnen, daß ein Anliegen im Übergang vom Boden zum Gefäßmantel zustande kommt. Dabei sind Rißbildungen, also die Zerstörung der Innenauskleidung, oft nicht zu vermeiden. Durch die starke Dehnungsbeanspruchung des Auskleidungsmaterials wird es vorzeitig abgenutzt und eine öftere Verwendung in Frage gestellt. In den meisten Fällen kann aber nicht erreicht werden, daß die zwischen Gefäßmantel und Innenauskleidung befindliche Luft beim Füllen völlig entweicht. Die bestehenden Luftpuffer bewirken unter anderem eine Bewegung der Innenauskleidung samt Füllung während des Transportes und verursachen ein Scheuern an der Gefäßwand, wodurch ebenfalls eine Zerstörung der Auskleidung hervorgerufen wird.Loose insertable or exchangeable inner linings for packaging vessels are so far in Bag or sack shape prepared and then inserted into the vessels. The primarily made of weldable Interior linings made of plastics are thus turned into bag-shaped containers formed by the walls lying flat on top of one another be connected in a straight line so that the bottom seam runs transversely. When importing the contents In the case of round or square vessels, the bag must expand near the bottom in such a way that a concern comes about in the transition from the bottom to the vessel jacket. There are cracks, so the destruction of the inner lining, often unavoidable. Due to the strong stretching stress of the lining material, it will wear out prematurely and more frequent use will be considered posed. In most cases, however, it cannot be achieved that between the vessel jacket and The air in the inner lining escapes completely when it is filled. The existing air buffers cause under among other things, a movement of the inner lining including the filling during transport and cause rubbing against the vessel wall, which also causes destruction of the lining.

Es sind auch Verfahren zum Auskleiden von Behältern bekannt, bei denen die dünne Kunststoffolie in die Falzverbindung zwischen Behältermantel und Boden einbezogen wird. Hierbei treten oft Zerstörungen bei der Auskleidung auf, die eine solche mechanische Beanspruchung nicht aushält. Dazu fehlt die Kontrolle über die absolut dichte Wirkung.There are also known methods for lining containers in which the thin plastic film in the seam connection between the container shell and the bottom is included. Destruction often occurs here in the lining, which cannot withstand such mechanical stress. This is missing control over the absolutely tight effect.

Durch die Erfindung sind die bezeichneten Nachteile beseitigt. Die Erfindung behandelt ein Verfahren zur Herstellung einer Innenauskleidung aus schweißbarem Kunststoff, die sich schließend gegen die Innenwandung des Gefäßes anlegt und wobei die Mantel- und Bodenfolien durch Schweißrundnähte in einfachster Weise angebracht werden. Damit ist die Alöglichkeit gegeben, die Innenauskleidung in genauer Dimensionierung herzustellen, die den Innenmaßen des jeweiligen Behältnisses entspricht. Die völlig geschlossene Ausführung der Auskleidung gewährleistet eine absolute Dichtigkeit und einen völligen Schutz für das Füllgut.The above-mentioned disadvantages are eliminated by the invention. The invention deals with a method for the production of an inner lining made of weldable plastic, which closes against the The inner wall of the vessel is applied and the casing and base foils are welded through circular seams can be attached in the simplest possible way. This gives the option of converting the inner lining in to produce more precise dimensions that correspond to the internal dimensions of the respective container. the completely closed execution of the lining ensures an absolute tightness and a complete Protection for the contents.

Das Verfahren gemäß der Erfindung besteht darin, daß zunächst ein den Innenmaßen des Behältermantels entsprechender vorgeformter Mantelteil der Auskleidung in den Behälter eingesetzt wird und dann der Einsteckboden, dessen den Behälterraum abschließender flacher Teil und umgebördelter Randteil vorher mit Auskleidungsfolie belegt worden ist, eingesetzt und nun die gegeneinanderliegenden Auskleidungsteile des Behältermantels und des um-The method according to the invention consists in that first the internal dimensions of the container jacket corresponding preformed shell part of the liner is inserted into the container and then the plug-in base, the flat part of which closes the container space and the flanged edge part has previously been covered with lining foil, inserted and now the lining parts lying opposite one another the container jacket and the surrounding

gebördelten Randes des Bodens miteinander verschweißt werden, woraufhin — nach erfolgtem Einbringen des Füllgutes — mit dem Deckel in gleicher Weise verfahren wird wie mit dem Boden. Die überstehenden Ränder werden durch Abschmelzen verbunden. Das Abschmelzen geschieht in der Form, daß die Verbindungsnaht bündig mit den Kopfenden des Gefäßes abschließt. Dieses Verfahren der Herstellung von Innenauskleidung«! aus schweißbaren Kunststoffen läßt sich bei Gefäßen aus beliebigem Werkstoff anwenden, insbesondere auch bei solchen aus Pappe.beaded edge of the floor are welded together, whereupon - after it has been brought in of the product - the lid is handled in the same way as the bottom. The protruding Edges are joined by melting. The melting takes place in the form that the connection seam is flush with the head ends of the vessel. This method of manufacture of inner lining «! made of weldable plastics can be used with vessels made of any material, in particular with those made from Cardboard.

Eine andere Art der Ausübung des Verfahrens gemaß der Erfindung besteht darin, daß die mit Innenauskleidung versehenen Behältermäntel und -boden zusammengesetzt werden, ohne daß die Innenauskleidung die Kopfenden überragt. Darauf erfolgt das Verschweißen im Bereich des Bordrandes der Böden durch beispielsweise das Elektroimpulsverfahren. Es können hierbei nach Bedarf eine, zwei oder mehrere Rundnähte nebeneinandergelegt werden, so daß in jedem Fall eine sichere Verbindung zwischen Boden und Mantelauskleidung erreicht wird.Another way of performing the procedure according to of the invention consists in the fact that the container jackets and bottoms provided with an inner lining be assembled without the inner lining protruding over the head ends. Then that happens Welding in the area of the shelf edge using, for example, the electric pulse method. It one, two or more round seams can be placed next to each other as required, so that in a secure connection between the floor and the jacket lining is achieved in each case.

Während bei der Anwendung des Abschmelzverfahreni zur Herstellung der Rundnähte nach Abziehen der Böden die Innenauskleidung herausgenommen werden kann, ist dies beispielsweise bei \^erwendung von Pappe als Werkstoff für die Gefäße bei der Anwendung des Elektroimpulsverfahrens nicht möglich, weil sich durch die Erwärmung im Bereich des Bordrandes der Böden der schweißbare Kunststoff gleichzeitig mit der Pappe verbindet und somit die Verbindung zwischen Behältermantel und Boden herst» 729 257While using the melting process to produce the round seams after peeling off the inner lining can be removed from the floors, this is for example in use of cardboard as a material for the vessels when using the electro-pulse method possible because the heat in the area of the board edge of the floors causes the weldable plastic at the same time connects to the cardboard and thus establishes the connection between the container shell and the bottom » 729 257
