Fig. 3 is a view of a portion of an apparatus for manufacturing the package with fittings for forming an intermediate web,

Fig. 4 shows a further section of the device with a star wheel for fixing the intermediate web and

Fig. 5 shows a portion of the device in which clamping fingers are provided.

1 in Fig. 1 is a flat cardboard blank, which is provided for producing a package for four cup-shaped containers arranged in two rows. The cardboard blank 1 has a top surface 2 , on each of which a side wall 5 or 6 is articulated via folding lines 3 and 4 . Within the fold lines 3 and 4 there are cut lines 7 into which the cup-shaped containers with their edge flanges are able to engage. In the middle of the top surface 2 there are two parallel rows of further incisions 8 , in which the edge flanges of the cup-shaped containers are also able to engage. On each of the two side walls 5 and 6 , a bottom wall section 11 or 12 is articulated via a further folding line 9 or 10 , which are folded over one another when the packaging is erected and closed, the section 11 being on the outside and the section 12 on the inside is coming.

The inner bottom section 12 has four sections one behind the other, divided by section lines 13 and 14 , from each of which an intermediate web 15 is formed. These intermediate webs 15 are each articulated to the bottom section 12 via fold line sections 16 and 17 and divided into two side sections 20 and an upper section 21 by further fold lines 18 and 19 . The two side sections 20 contain recesses 22 into which the cup-shaped containers can engage with their lower section. The upper section 21 of the intermediate web 15 has an elongated hole-shaped recess 23 , into which a driver engages when the packaging is erected.

Between each two adjacent intermediate webs 15 - separated by the cutting lines 13 and 14 - a tab 24 is arranged, which is somewhat shorter than the flat intermediate web 15 and is therefore formed on only one side on the bottom section 12 . The two cutting lines 13 and 14 are interrupted by punctiform bridges 26 and 27 , which ensure that the tabs only emerge from the plane of the bottom section 12 when these bridges are severed. When the intermediate webs 15 are erected, the two side sections 20 are folded upward and the free end of the tabs 24 is glued to the opposite edge of the base section 12 , so that the intermediate webs are fixed.

In Fig. 2, a fully erected, equipped with cup-shaped containers 25 and sealed package is shown.

Using the other figures, the method for Erecting this packaging will be explained.

In Fig. 3, two guide rails 30 are shown on which the cardboard blank 1 is transported via not shown carriers. Above these rails 30 , a plurality of shaped pieces 32 are attached to a transport chain 31 , the outer shape of which corresponds to the inner shape of the intermediate webs 15 to be formed. These fittings are moved down against the two rails 30 and press the sections 20 and 21 of the intermediate web down, whereby this intermediate web is formed. On the underside of the shaped pieces 32 there is a mandrel 33 which engages in the cutout 23 in the blank and also pulls the blank 1 along so that it cannot warp during the deformation. The tab 24 is at the same time slightly pushed out of the plane of the bottom section 12 , so that its free end and the opposite section of the bottom section can slide over one another. Before sliding over one another, an adhesive is applied in this area and then the two superimposed material sections are pressed together by means of a star wheel 40 shown in FIG. 4.

The cup-shaped container 25 are now moved from both sides against the underside of the blank 1 , which is still lying flat. At the same time, the web 42 lying between the incisions 8 in the top surface 2 is pressed downward by knife-shaped pressure pieces fastened to a circumferential chain, not shown, so that the edge flanges of the containers can engage in the incisions and then with a section on the top of the rest respective web 42 . When the two side walls 5 and 6 are subsequently folded down by folding rails (not shown), opposite sections of the edge flanges engage in the cutting lines 7, as a result of which the edge flanges are already very well anchored to the top surface 2 . Thereupon, the two rows of containers are slightly tilted apart by rails engaging on the projecting edge flange sections, further rails holding the central section of the top surface 2 and the containers in this central region and preventing their rising. As a result, the gap between the containers is somewhat enlarged, so that the intermediate web 15 formed on the base section 12 can easily penetrate between the containers; a folding ruler, not shown, is again provided for this. To tension the two bottom sections 11 and 12 and thus to achieve a firm fit of the packaging on the containers 25 , clamping fingers 50 are provided, which are fastened to two circumferential chains 51 and engage in openings 53 and 54 , respectively, which then adjoin the two folding lines 9 and 10 are provided in the two bottom sections 11 and 12 . During this tensioning process, the two bottom sections 11 and 12 are then glued together.
