Packaging container that can be closed on all sides.

The innovation relates to a packaging container made of metal, coated or uncoated paper or plastic in the form of a pyramid, which can be closed on all sides and which is folded in one piece from a square, preferably square blank without waste and through at its seams
Gluing, soldering, sealing or welding is connected.

It is known to make cups from a rectangular or aegHien to produce a shaped blank. However, these are not suitable or only share with the help of separate locking devices Packing zv / corners.

Furthermore, it is known to provide a collapsible pyramid-shaped filling funnel from a relatively complicated blank, which has to be produced at the expense of considerable waste, with a series of pre-folded or grooved fold lines

Gluing, sealing or the like. To close. Separate flaps on the blank are used to maintain the funnel shape during casting.

For the production of packaging containers it is also already known to start from a square blank, in this one at one corner a square bottom part with fold lines to limit and one the bottom part and the rest of the

φ a diagonal folding line to be provided. This The blank is folded up along the diagonal fold line with the bottom part folded in a gusset-like manner and at all Sealed edges. In this folded state, the empty container is stacked and shipped. This leads to that to difficulties than in the area of the wrapped lap the container wall lies four times, but otherwise only twice. For filling, the tip of the container is cut off and under filling of the content "inflated". But none of them can do this

α flat side surfaces are obtained, resulting in the stacking of the filled Container difficult. In addition, this type of manufacture is limited to materials that are suitable for "inflation" during Suitable for filling.

It is the task of the innovation, a container of the aforementioned To create a kind that can be made of rigid material without waste, has flat boundary surfaces and can be stacked easily and space-saving both when empty and when full.

For this purpose, the invention provides that on a Mandrel or container folded into a three-sided pyramid by means of grooved fold lines and connected at its longitudinal edges has a bottom flap having the shape of a triangle, the edges of which can be connected to the narrow sides of the pyramid body are. Due to the triangular bottom flap, the container can be folded from the outset with flat side surfaces and the bottom flap can be easily closed before or after filling. Thanks to this training, too Material used to manufacture the container and secure stacking achieved. At the same time the container receives greater strength. When empty, the new containers can either be nested with the bottom flap open or using one to cross the bottom flap and the adjoining side surface from tip to tip Fold the fold line together in such a way that triangular elements with the same double position are obtained.

A significant simplification in the manufacture of the container can be achieved by bringing all of the seams together of the inner edge zones are formed and therefore point outwards after their completion. This will it is possible to form the individual seams only by jaws that engage from the outside and move against one another, wherein this has the advantage that internal abutting edges are avoided.

The outer surfaces of the container from the square blank can be folded on a mandrel and then connected to one another along their seam, preferably on their inside to which, if necessary, after prior approval, the container bottom is hammered in and attached with its edge zones to the G-egenflachen of the side walls.

Here, containers of different dimensions can be folded on one and the same mandrel, since on the latter only the Jacket surfaces are brought into their position relative to one another and welded together at the open longitudinal edges, during the After removing the prepared container from the mandrel and, if necessary, after filling, the bottom part is knocked in and is then attached with its free edges to the edge zones of the jacket surface.

The packaging container does not need to be filled through the bottom. Rather, it is also conceivable that on the part of the manufacturer the pack is completely closed and that the top of the pack is cut off and through by the filling machine the container is filled through this, after which this tip is welded again by two parallel jaws and can thus be closed. In this Palle one would Tear-off perforation provided by the manufacturer can already be used by the bottling plant for opening, and this with it are no longer available to the consumer, according to fire it is provided that the container from the outset

provides two perforations at the tip of the pyramid, of which the top is cut off by the bottling plant and the below is used by the consumer.

It is also possible to manufacture the pack without the aid of a mandrel. In this case all pre-folded edges delimiting the interior of the pack. You can then first connect the edges and then Fold in the bottom and fasten it too. In order to have better transport and cheaper packaging options for the To enable a pack that is not yet completely closed, a half-end of the Mayitelfläclie can be added in the blank Pre-folded diagonals can also be provided. After the edges are joined together, the pack can then be flat are placed, with the lateral surfaces come to rest on one another.

The drawing gives an embodiment of the innovation in schematic form again.

FIG. 3 shows a perspective view of a finished container which is produced from a blank according to FIG. 1 has been.

Edge zones 4 and 5, according to Pig.2, the longitudinal seam of the pyramid ". The bottom part 6 formed by a corner segment the packaging is an isosceles, right-angled triangle and is attached to the edge zones 7 and 10 with its edge zones 8 and 9 after the floor has been hammered in. for example welded. Scoring lines 11 can already be arranged on the blank in such a way that the later finished Packaging makes it easier to break off or tear off the tip to form a drainage opening.

Like the Pig. 2 and 5, the seams are formed by bringing the inner edge zones together, the container being placed on the edge zones 7 and 8 or 9 and 10 ^{according to I 1 Xg.3.} The figures also show that the height of the pyramid corresponds to the edge length or the Uaht length of the edges 4, 5 and that by this design the outer surface 2 forms the front surface which can be used for advertising purposes. The pyramid shape with flat side surfaces in connection with the outwardly pointing handle edges leads to a great rigidity of the container.

In order to facilitate the connection between the edge zones 8, 9 of the base part 6 and the edge zones 7, 10 of the lateral surfaces 1, 3, The edge zones of the bottom part can be pre-folded by suitable devices so that they are folded when the At the bottom, nestle more easily against the edge zones 7, 10 of the lateral surfaces and weld them by means of appropriately designed jaws or can be sealed.

The new type of packaging had the further advantage that the entire coating, if necessary, can be done in one operation before folding and is extremely easy to perform. Here, for example, a Coating material is used that is also suitable for forming the later connecting seams.
