^ / jerpaokungseinheit

The hiring relates to a packaging container consisting of a stiff carrier sheet, dessin Bodenbereioh for the support of a Verpaokungegumento is intended and one for at least partial covering of the packaging object certain film, which around two opposing first edges of the bottom area of the carrier sheet led around and on the remote from the contact side of the Yerpaokung object Side of the floor area is sealed with the carrier sheet.

Such a Verpaokungseinheit is for example from the DT-OS 2,017,630 known.

The hiring is based on the task of such a packaging? to design unit in such a way that the item to be packaged is largely shock-proof and contact-protected.

To solve this problem it is proposed according to the innovation, that on the two opposite other edges the bottom area of the support sheet can be folded upwards Hang.

A particularly effective shock and contact protection is through the Merkeal of claim 2 reached.

Due to the feature of claim 3, a packaging unit that is dimensionally stable even under load is created.

The features of claim 4 provide additional protection for the item to be packaged.

Claim 5 shows a possibility of fastening the film on the carrier sheet, which is special erweiöt, would be on the same side of the O! is to be sealed, on which the Verpaokungsartikel is placed. This feature is of independent importance.

The feature of claim 6, which has an independent meaning, allows the object to be packaged on? Em Tighten the carrier sheet and, if necessary, after once done Save the solution again.

The feature of the claim 7 brings a further improvement of the stoßeonutzes by taking advantage of the zueöimittechnischen Reasons inevitably occurring secondary lobes.

The feature of claim 8 enables additional security of the Yerpaokung object on the carrier sheet.

The feature of claim 9, "which is also of independent significance, on the one hand ensures a particularly simple one Manufacture of the multi-pack unit and, on the other hand, securing the Yerpaokung object against slipping

7213351 19.0171

on the carrier area S, security, which despite the very swamp of the Banderole not guaranteed% 3re if the banderole would not be glued or sealed to the underside of the carrier plate.

The feature of claim 10 gives, on the one hand, a sufficient connection of the band and carrier sheet and, on the other hand, provides ensure that the carrier sheet due to the weight of the packaging item with the one at the bottom ä * s sealed banderole section adjoining the carrier sheet will enter a heating zone as soon as the carrier sheet and banderole lie on correspondingly small contact surfaces.

The feature of claim 17 ensures that there are no compromises on the other hand, closed with regard to optimal shrinkage properties and good adhesion between film and carrier sheet Need to become.

Further advantageous features of the hiring result from the subclaims not mentioned in detail.

In the drawing, the Verpaokungseinheit according to the innovation is shown annand of exemplary embodiments Mohematisoh, the will be described in detail below.

The drawing shows in: 1 shows a packaging unit according to the invention with a

The gluing of the band 16 on the underside of the carrier sheet 12 can be according to the innovation according to the method for Carry out manufacture of the Verpaokungseinheit 10 under high pressure at the Verklebestellea. This process is based on the pig. 2 and 3 shown. There is a packaging unit

10 on a conveyor belt 24, which runs through a shrink tunnel 26 indicated in dash-dotted lines, in dom the banderole 16 is dumped. The conveyor belt 24 weict Elevations 28 arranged in a Yerlcle pattern are smaller Area dimensions on which the carrier sheet 12 and the heavy Verpaokungsartikel H lying on it areas of the band 16 lying between the underside of the carrier sheet 12 and the elevations 28 press. she Due to the shrinking atmosphere prevailing in the shrink tunnel 26, the "a" warmth band is reduced to a Brought temperature close to the sealing temperature of the adhesion promoting Layer 18 of the band 16 corresponds, so that at the points where the band 16 on the bumps 28 rests, a relatively firm connection of the band to the carrier sheet 12 is effected. Sin rummaging around the Banderole 16 around the edges 20 of the carrier sheet 3 12 is with excluded from this connection, so that even heavy packaging items fat in their support area on the carrier sheet 12 are held.

The packaging unit 110 produced according to FIGS. 4 to 6 also consists of a carrier sheet 112. an in a central Auflagebereioh 113 lying Verpaokartikel 114 and a shrink film 116 covering it. The carrier sheet 112 is rectangular and at a distance from the bottom surface of the Verpaokungsgegenstandee 114 with four pre-embossed folding edges 115 and 117, wel3he the central Support area 113 as well as lateral lobes 121, 123 and secondary lobes 125 define. The lifting flaps are through incisions 127 in the extension of the folding edges 115 in the side flaps 123 disconnected.

During the manufacture of the packaging unit 110, after placing The shrink film 116 according to FIG. 4 is the same on the carrier sheet 112 overlying ends with this carrier sheet 112 with

Sealed by means of a sealing ball reindeer 131. The Siege1-s cells 133 are outside of the central circulation area 113 parallel to the fold edges 117 on the side flaps 123.

After the shrink wrap has been shrunk the side lobes 123 under the central support area 113 folded. At the same time, the shrink film 11C is further tensioned in addition to the shrinkage tension, so that the packaging material 114 it is fixed * The S # beslappat * 125 will be then folded under the side flaps 121, the latter bent up to the Verpaokungsartikel 114 and in this position by means of an adhesive strip 133 fixed. The side lobes 121 and the secondary lobes 125 form thus a side protection for the packaging item 114. The packaging unit 110 in the same way as the packaging unit 10 as an insert for a container indicated in dash-dotted lines J22 can be used.

The additional pretension imparted to the film by the folding under of the side flaps 123 can be achieved by folding it back the lateral lappex »can be eliminated again in its original position. This gives the possibility of an object covered by shrunk film, on the one hand, by folding it under of the side flaps and by unfolding them to solve again.
