appropriate shape. In detail are to this The following work steps are required, which are usually carried out manually:

a) Erecting the folding box

b) Closing the folding box bottom

c) Erecting the block bottom bag

d) filling and sealing the bag

e) Closing the folding box.

This is where the innovation comes in. The objective was to reduce the number of work steps and thus the Reduce costs in the assembly plant. The task The innovation is therefore to be seen in the development of a folding box based on the collapsed The pack can be set up quickly and easily and made available for filling.

This object is achieved according to the invention in that the folding box has no bottom and the block bottom bag is only glued to the broad sides of the folding box.

The block bottom bag is advantageously additionally reinforced in the bottom area (bottom reinforcement).

According to a preferred embodiment of the innovation, the block bottom bag is also in the manner with creases provided that it folds inward on the bottom and on the narrow sides when the folding box is folded up.

The advantages achieved with the innovation are primarily a reduction in packaging costs, because the relatively cumbersome operation of the bottom seal is omitted. So far, for this purpose - the bottom flaps of the folding box are folded down and locked with a tuck-in flap. The new foldable box needs, based on the folded flat pack, only by applying pressure from the side.

to be judged and is then ready for bottling. This also creates the prerequisites for a fully automatic assembly fulfilled. The still The remaining work steps can be integrated into a packaging line without major mechanical engineering effort will.

The innovation is explained in more detail below with reference to drawings. Show it

Fig. 1 shows the complete erected folding box

Fig. 2 shows the bottom area of the erected folding box and

3 shows the bottom area of the folding box in the semi-erected state.

The folding box according to FIG. 1 consists of a cuboid Box 1 and the standard block bottom bag 2 glued on the inside made of plastic or metal or Plastic-laminated paper. The inner bag 2 is practically everywhere on the walls of the folding box and is glued to the walls of the folding box on the broad sides 3 and 4. The side walls 5 and 6 are longitudinal their center line provided with creases 7. The folding box is completely open at the bottom; i.e. they are missing otherwise usual bottom flaps. The folding box thus forms a cardboard envelope for the inner bag 2, which is open at the bottom is. The inner bag 2 is therefore directly on the ground

Ii touch on which the package stands. In the floor area If the inner bag 2 is reinforced by a glued-on sheet 8 made of paper or cardboard. At the top, the Packing In the usual catfish by sealing the inner bag 2 and by folding over the incised wall parts 9, 10, 11, 12 of the folding box 1 are closed.

From Flg. 3 It can be seen that Im amalgamated or semi-erect state the rare walls 5 and 6 of the box are folded outwards (creases 7). On the other hand, the inner bag is folded inwards at the bottom and at the narrow edges (Krilck folds 13 and 17). This folding ensures that the inner bag 2 does not form arbitrary folds and wrinkles.

To erect the folding box, all that is needed is pressure t5 in the opposite direction on the two folds 7 can be exercised. When erecting, the inner bag attaches itself to the walls of the folding box (see Figs. 1 and 2).

It has surprisingly been found that the innovation (elimination of the box bottom) the The stability of the pack and the mechanical stability with regard to storage are not inadmissible Way to be affected.
