The invention relates to an intermediate layer for the arrangement

between stacked packaging boxes,

The invention further relates to an arrangement of packaging boxes comprising a plurality of stacked, open-topped packaging boxes which have a circumferential edge on their open side and which are each filled with a large number of cylindrical bodies, in particular open plastic tube bodies, which have an open end the circumferential edge of the packaging box protrude and a support surface for one arranged above it

Form packing box.

Cylindrical plastic bodies are usually produced in an extruder. The extruder produces a tubular endless body which is divided into individual tube sections by cutting to length, which are separated, gg £. be subjected to further processing steps and placed in packaging boxes for transport. Such cylindrical bodies occur, for example, in the manufacture of plastic tubes. The tube sections here form the plastic tube bodies, which have a tube head at one of their two open ends. The other end remains open to allow filling with the respective product, e.g. Cosmetic product to enable. After filling, the open end is squeezed together to form a flat end section

welded.

Since the production of the plastic tube body and the

takes place, large quantities of empty plastic tube bodies have to be transported from the tube manufacturer to the filling company. For this purpose, the empty plastic tube bodies are placed next to one another in a packaging box with the open end facing up. A plurality of such filled packaging boxes are stacked on top of one another and on transport pallets

transported.

The length of the cylindrical body, especially the empty plastic tube body, can vary depending on the customer's requirements. The individual packaging boxes usually contain cylindrical bodies that are of the same length so that the height of the packaging volume is optimally used. An adaptation of the packaging boxes to the respective length of the cylindrical bodies contained therein would require packaging boxes of different heights to be kept in stock, which is logistically complex. Instead, a single version of the packaging box with a standard height is used even if the body length of the cylindrical body varies. In order to minimize the volume to be transported, the standard height is based on the lowest expected length of the cylindrical body. However, this means that the bodies that exceed the lowest expected length, with their open end over

protrude from the top of the packaging box.

Here, the cylindrical bodies arranged in a lower packaging box, with their open ends protruding beyond the box opening, form a support surface for one arranged in the stack above

Weight of the packaging boxes arranged further up in the stack are loaded. This can in particular lead to a deformation of the cylindrical bodies arranged in the packaging box if the plastic bodies are particularly thin-walled and therefore have a low inherent stability. There is also a high risk of deformation of the cylindrical body and the associated damage to it if the individual packaging boxes stacked on top of each other are not aligned exactly one above the other, but are laterally offset from one another Arranged in the corner area

cylindrical body.

The invention therefore aims to minimize the risk of deformation of the cylindrical body in the packaging box

Reduce packaging material consumption.

To solve this problem, the invention provides, according to a first aspect, an intermediate layer for the arrangement between stacked packaging boxes,

comprising a flat element, soft a plurality of

Has recesses with a circular edge,

According to a second aspect, the invention provides an arrangement of packaging boxes, comprising a plurality of stacked, open-top packaging boxes, which have a circumferential edge on their open side and each with a

Large number of cylindrical bodies, especially open ones

Plastic tube bodies, which protrude with one open end over the circumferential edge of the packaging box and form a support surface for a packaging box arranged above, an intermediate layer according to the first aspect of the invention being arranged between the support surface and the packaging box arranged above, the depressions the intermediate layer into the open ends of the cylindrical

Body intervene.

Because the depressions of the intermediate layer engage in the open ends of the cylindrical bodies, the cylindrical bodies are stabilized in the engaging area so that the loads from the packaging boxes above do not lead to deformation of the cylindrical bodies. It is preferably provided here that the circular edge of the depressions essentially has a diameter corresponding to the inner diameter of the cylindrical body. This ensures that the circular edge of the depressions in each case rests on the inside against the circular open end of the cylindrical body and reliably secures the open end against inward displacement. In particular, the recess stabilizes the circular cross-sectional shape of the with its circular edge

cylindrical container. The depressions are preferably designed to be concave, in particular hemispherical. This makes insertion easier

of the recesses in the cylindrical body.

In a manner known per se, the cylindrical bodies

in the packaging box preferably in a plurality

arranged by rows, the cylindrical bodies of one row being arranged offset to the cylindrical bodies of an adjacent row. In this case it is provided with respect to the intermediate layer that the depressions of the intermediate layer are arranged so that each depression in

the open end of one of the cylindrical bodies engages.

A recess does not have to be assigned to each cylindrical body, but the recesses can be arranged in such a way that, for example, they only engage in every second cylindrical body. However, it is preferably provided that a recess is assigned to each cylindrical body. For this purpose, the depressions are arranged in the same row pattern as the cylindrical bodies. In particular, the plurality of wells is arranged in a plurality of rows, the wells of a row to the wells of a

adjacent row are arranged offset.

Because the intermediate layer is formed by a flat element, it can be arranged in a space-saving manner between two packaging boxes stacked on top of one another. The flat element here preferably covers the entire opening of the packaging box and takes on the function of a lid, so that a separate lid can be dispensed with. At the same time, the intermediate layer acts as a load-distributing element, so that forces acting locally on the packaging boxes from above are distributed over a larger area and accordingly do not lead to deformation of individual cylindrical bodies

6 The ridiculous element and the indentations are preferred

formed integrally with one another.

It is preferably provided here that the flat element is made as a film made of a plastic, in particular a thermoplastic, such as e.g. Polyethylene terephthalate (PET). A thermoplastic allows simple and inexpensive production of the intermediate layer, with the depressions preferably being made by a deep-drawing process

The flat element preferably has a thickness of 0.1-1 mm

on.

The intermediate layer can be made transparent or translucent so that the recesses engage correctly in the open ends of the cylindrical bodies

can be better monitored.

According to a preferred embodiment of the invention, the flat element has a raised, in particular bent, flat area which preferably extends around the entire circumference of the flat element. Such a raised edge area forms a stacking aid. In particular, it is provided here that the erected edge area of the flat element has a lateral stop for the bottom of the element arranged above it

Packaging box trains. In the context of the invention, conventional

Packaging boxes are used. Especially

Cardboard packaging boxes can be used.

As is customary per se, cuboid packaging boxes are preferred. However, the invention can be used with other forms of packaging boxes. The intermediate layer is then not rectangular, but to the respective plan shape of the packaging box

customized.

In addition to the intermediate layer, a further layer can preferably be arranged between the support surface of the cylindrical body and the packaging box arranged above it. The further layer can be arranged between the support surface of the cylindrical body and the intermediate layer arranged above it. The further layer consists, for example, of a flexible film, in particular a polyethylene film, in particular of HDPE, which adapts to the shape of the depressions. The further layer has the function of closing the open ends of the cylindrical body and thus against the

Protect ingress of contamination.

Alternatively, the cylindrical bodies in the packaging box can be contained in a flexible sack, e.g. consists of a polyethylene film. The open end of the sack is folded over or closed after the intermediate layer has been placed on top of the intermediate layer, so that this also provides protection against

the penetration of impurities is achieved.
