Description

The subject of patent application E 15142 VII / 54 f is an essentially flat-lying container for liquids, pastes and powdery bulk material made of cardboard, preferably corrugated cardboard, with a Hermetically sealable insert made of paper, preferably protruding beyond the jacket edges coated paper, foil öd. Like., the one triangular in cross-section, through retractable and with Bottom and lid inserts that can be connected to the jacket edges, closable filling space and an insert has, the top and bottom parts in the ready-to-use state unfolded in plan view approximately form a rhombus. In order to assemble this container ready-made, which is preferably done on site the use happens, the container blank is expediently by simple pressure on the through the Center of a container wall extending fold line and this opposite fold line brought into use form, whereupon the lid for the bottom and after filling the container and closing the head part of the insert, expediently by sealing, the lid can be used for the head.

It has now been found that the container is advantageously improved for particularly high loads can be, if on the cardboard blank itself for bottom and lid formation on two side walls triangular and triangular or trapezoidal approaches are provided on the third side wall. To Transfer of the flat, transported and stored container blank to the ready-to-use State, these approaches to the formation of the bottom or cover only need to be turned over, where they are expediently connected to one another, for example by stapling or gluing. In general you will get the floor ready for use immediately after bringing the container form, the lid of course only after filling the container. It was found, surprisingly, that the container according to the main application E 15142 VII / 54 f by the present invention a considerable Experience increases in its strength and transport security. A ^ requests proved that the execution of the container according to the present invention withstands much higher stresses. In particular it was found completely unexpected that when the filled container was subjected to heavy loads Throwing and falling of the bag insert in the case of the container design according to the invention, any stresses withstands as long as the container wall remains intact, while in the previous version the bag insert burst under heavy use or tore, while the container wall no Showed damage. The strength of the earlier version was therefore in a filled and container for liquids

closed state depending on the strength of the inner bag, while according to the present Invention depends only on the strength of the container wall itself, so accordingly considerably is bigger. The present invention therefore utilizes the maximum strength of the outer container. There is also the advantage that with less high stresses for production lighter paper can be used in the inner bag. In addition, according to the present invention the entire container including base and lid parts are made from a single blank. Finally, closing the The container jacket is made easier and the filling and sealing of the inner bag is also considerably simplified. because now with the container erected, the upper folding edges of the bag are at the same height as the Edges of the outer container.

The container according to the invention can be embodied in various ways. Preferably are on the bottom and on the lid side of the container blank each hinged three tabs, of which the have a trapezoidal shape on the foldable long side of the container and preferably to form the bottom or Cover must be tucked in first, while the other two, opposite tabs are triangular Show the shape and fold it onto the first flap. You can be with her, preferably by gluing. The lashing tabs on the foldable long side of the container Instead of a trapezoidal shape, they can also have a triangular shape and cover the entire opening. Due to the preferential

However, if the trapezoidal shape is chosen wisely, material is saved.

In the drawing is an example embodiment of the container according to the invention. ■■■ '■.'
