FIG. 7 shows securing the fully extended container portion so as not to slip when transported.

In a suitable form the packaging container is made in one piece and is a planar base 1, top surface supported by what is known as a film hinge 24 which is a collapsible connecting tab as shown in FIG. It consists of (2) and four sides. The faces can be bent, resulting in a parallelepiped container as shown in FIG. The container is safely transported by a strap (not shown) placed around the recess 25 formed around the nested container. The strap may also include a carrying handle, but instead of the carrying handle a gripping depression may be provided on the outside of the package. With the exception of such straps, all parts of the packaging according to the invention can be used frequently and are suitable for conveyance.

To open the container, a strap made of the material used to hold the pallet is simplified. The upper surface 2 is raised and the side 19 can be simply unfolded. Therefore, the pancakes can be packaged freely. The pancakes wound on the hub 13 are stacked one on top of the other on a specially made hub support 11. The hub support has an integral handle 14 which, together with the pancake, allows the support to be safely lifted out of the package and transported to a treatment site, which is usually located in a clean room. do. The packaging itself does not generate any dust, for example cardboard packaging, and can be transported to a clean room as a unit. The two opposing corners on the inner side of the bottom are provided with a grip groove 21 for lifting the pancake.

When unfolded again, the package is ready to be laminated and returned to the manufacturer in a convenient and space-saving manner on the pallet by the aid of an integral lamination aid. Because of the planar shape, corners and edges do not protrude, and the packaging can be easily and advantageously cleaned. This helps the flow channel to dry. There is no corner where the cleaning liquid can accumulate. Then, a new packaging cycle is started as already described.

The packaging design will be described in detail. In order to protect the package contents against dust and moisture, the container has a side or bottom, or an outer edge of the top, which seals the strip 18 exposed in the unfolded state, which is complementary to the corresponding surface while stacked. Combine with By means of suitable technical means such strips and grooves can be configured to snap together in the inserted position. However, there may be corresponding notches in the hinge regions of the base 1 and side 19.

In the folded state, the hub support 11 is securely rotatably connected to the bottom and top surfaces 1 and 2 in the packaging container. For this purpose, the bottom and the top have recesses 3, 4 in the inner central part thereof, from which the individual protrusions 5, 6, 7, 8 protrude. The end faces 9, 10 of the partially cylindrical hub support are formed so that the end faces 9, 10 can be corrected so as not to rotate into recesses in the bottom and top surfaces.

And, as shown in FIG. 3, the hub support has a shoulder 12 on the lower end face 10 assigned to the bottom, which supports the bottom adjacent to the inner bore of the lowest hub 13. do. In the upper end face 9 the hub support has a U-shaped carrying handle 14 which is provided with two locking positions in a preferred configuration. To carry the package, the handle in the upper locking position is suitable for carrying the finished pancake, and in the lower position the handle is recessed into the hub support. For this purpose, the two uprights 15, 16 of the handle can be fixed in the recess of the hub support.

The two uprights 15, 16 of the carrying handle 14 have a detent (not shown) for convenience, the detent locks the handle in an extended and recessed state, if the packaging is too heavy the carrying handle is in contact with the hub support. It can be configured integrally. In this case, it is also possible to hold by the grip groove 17 provided under the handle.

To facilitate the removal of the individual pancakes, the hub support has two concave grooves 25, 26 that face in the form of circular segments over their entire height.

A concave label panel 28 may be provided on one of the outer surfaces of the package, which additionally has a grip groove for removing or replacing the label.

Instead of the one-piece construction described above, the container according to the invention can be made of two or more sides, with FIGS. 4 and 5 showing two possible embodiments, where the bottom and the top are two sides and Otherwise, the bottom is joined to the four sides and a separate top is placed thereon.

In order to transport several packaging containers together in the unfolded state, the container is provided with a groove 23 along the outer edge of the bottom or top for convenience, the groove having a corresponding complementary strip 18 of the unfolded side 19. Thus, several containers stacked on top of one another can be safely transported without slipping. This is shown in FIG. In addition, each container may be provided with a stud structure on its outer surface, which is described for example in EP 0 217 254. In addition, the packaging container may be provided with recesses and upright pits for stacking pallets well underneath.

7 shows how two (or more) unwrapped packages are stacked one on top of another for conveyance, with the protrusions 5 on the inside of the underside engaging with the corresponding recesses on the outside.

In the case of a package with two sides, the surface can be offset to make as many packing heights as possible. In addition, the peripheral sealing strips may be asymmetrical to form various pavement heights as used.

The shape of the hub support is made so that several hub supports can be stacked one on top of the other. The shape is conveniently hollow so that it can be fixed on the auxiliary mandrel during the manufacturing process.

In a preferred construction, the packaging container consists of steel plastic, such as polypropylene or acrylonitrile-butadiene-styrene copolymer. The container is preferably made of two walls by injection molding process or extrusion brow molding. This additionally protects the container significantly from impact and climate influences.

FIELD OF THE INVENTION The present invention relates to an integrally or multiple-sided parallelepiped container for tape-shaped recording media wound on a hub and stacked on top of one with an inner bore provided, each side being molded It consists of a bottom, top and side that are joined to each other by a machined film hinge, the hub support being pushed through the inner bore of the hub.

Known as pancake packaging, these are sold worldwide by magnetic tape manufacturers. In such packaging the magnetic tape is wound on a hub, for example a flangeless hub, known as a NAB hub or a stackable hub according to US Pat. No. 4,081,151. At present, these pancakes are packaged individually or in multipack form, wrapped in shrink film or supported by various types of cardboard boxes.

The disadvantage of such individual packaging is that the packaging material is consumed in large quantities. Multiple packaging of magnetic tape is described in publications US 3 543 922, US 4 708 246, US 4 955 471, EP 0 320 751, DE-U 8 900 709, DE-U 8 912 747 and DE-U 8 912 749. It is. Such multi-packages consist of relatively bulky styropoles, which are quite inconvenient to transport and have to be discarded when unpacking, and such co-packages are also supported by plastic pallets and sleeves, said sleeves Should be a relatively complex configuration, and in some cases the sides of the package may not be adequately protected because the sides are only wrapped by shrink-fixed films on the package. Therefore, such multiple packages must additionally be placed in a transport outer case.

Pancake packaging that can be reused or recycled without the use of styropol is described in DE-U 9 011 867 and German application P 40 25 906. However, such packaging containers require many parts and in some cases cannot provide adequate protection during transport and from dust.

It is therefore an object of the present invention to provide a package for pancakes of the general type which satisfies the following conditions:

Limit the amount of packaging material that is discarded to the minimum possible;

-Simple configuration.

-Protect during transport and from dust.

-Easy to assemble and dismantle

-Not large to carry

-Reusable

-No external packaging required

This object is achieved by a packaging having the features set out in the limitations of claim 1. Other advantages of the invention are indicated in the dependent claims, the drawings and the description.
