BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to cardboard cartons for the packaging of pharmaceuticals, particularly for packaging pharmaceuticals packaged in blisters.

0002

BACKGROUND OF THE INVENTION Medications packaged in blisters have traditionally been
It is packaged in a folding carton made of cardboard, which can be closed symmetrically on both sides by means of so-called plug-in closures. These plug-in closures are usually sheet-like rectangular extensions of the front and rear ends of the carton. This extension has the dimensions of the side of the carton that is closed at right angles to the front and back sides, plus the size of the tab that is bent from the side and inserted into the carton during the closed state. To close the carton, the sheet-like extension can be bent by folding at 90° on the front and back sides.

[0003] Medications are increasingly being used, especially by elderly patients, for whom the packaging surrounding them must be easy to handle as well as the medicines. However, in the prior art of collapsible cartons with plug-in closures, this is only described to a very unsatisfactory extent.

0004

[Problem to be Solved by the Invention] Once such a folding carton is opened, usually on one side, medicines, such as medicines packaged in a blister, may accidentally slip out. . Additionally, opening such collapsible cartons with plug-in closures is particularly inconvenient, especially for patients with finger joint disorders. Indeed, in order to open such a carton, the patient must press his finger or nail between the aforementioned tab of the plug-in closure and the front or back side of the carton and pull the tab from inside the carton. Doing so may cause the plug-in closure, which is itself made of cardboard, such as a folding carton, to become irreversibly distorted or lose its original surface area stability even after being restored. It is clear that this is unavoidable. Since the other side of the carton can also be opened, the above-mentioned problems also apply to this side. In short, this results in a considerable loss of stability of the folding carton during opening and closing, especially when a certain number of blisters have already been removed from the carton and the carton no longer squeezes the entire contents. This applies when the packaging material (blister) no longer provides stability. A further disadvantage of the above-mentioned folding cartons may be that after opening the folding carton, the blisters are not exposed, or even partially exposed, thus preventing removal of the blisters. When you try to pop the blister,
Typically, the entire contents of the folding carton simply slide out. Due to the fact that two sides of the carton can be opened, users of such folding cartons are uncertain whether they will even open the opposite side, where the blister is not hidden by the insert.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a folding carton for pharmaceuticals which eliminates the above-mentioned disadvantages.

[0006]

This object is achieved by a cardboard carton for drug packaging, which is provided with a cap-like closure on one side.

The carton according to the invention is preferably utilized for blister packaging. Cartons of this type are known per se and are used for packaging cigarettes. According to European Published Patent Application 348,840, these cartons can also contain a desiccant agent that protects the contents of the carton against the ingress of moisture.

The carton according to the invention for packaging medicines has a three-dimensional shape with vertically or horizontally long rectangular or square sides. The ratio of the front and back side lengths of the carton is preferably less than 2:1. In the case of two opposing sides, this ratio is preferably greater than or equal to 2:1.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The carton 1 itself is preferably formed in two layers in the region of the cap-like closure 2, so that two layers of cardboard of different thicknesses can be used. However, the inner layer 3 has been removed, at least on one side, where the flaps leave. Therefore, the blister 4 can be taken out reliably. Preferably, this inner layer is also partially removed at the front side of the carton (with a side length ratio of 2:1).
less than). Therefore, after opening the cap-like closure, the blister strip 4 and the drug 5 can be immediately seen from above. However, this opening 6 in the front inner layer of the carton is preferably smaller than the outer layer formed by the cap-like closure 2 applied.

The opening on one side of the carton, which can be closed by a cap-like closure, is preferably provided on one side of the side of the carton according to the present invention, and the ratio of the side lengths thereof is preferably 2:1 or more. In each case, the openings can also be formed on the entire side surface. According to the various designs of the carton according to the invention, the closure cap can be closed either on the short side (FIG. 1) or on the long side (FIG. 2).

[0011] The closure cap 2 has a three-dimensional shape,
It is stable to begin with. The side of the closure cap which covers the opening 6 during closure is larger than the side of the cap whose opposite part continues on the rear side of the carton and is divided only by folding. The side of the carton designated as the back side is the side opposite the side with the opening 6. In the closed state of the carton, the front side of the closure cap covers the inner layer 3 of the carton and forms a flat surface with these sides since it corresponds to the outer layer of the sides of the carton at the location of the opening of the carton. .

[0012] The front side of the carton according to the invention is divided by the closure cap, preferably in a ratio of no more than 3:1, the smaller part corresponding to the front part formed by the closure cap. On the back side of the carton, a fold dividing the "section" of the closure cap from the back side divides the back side preferably in a ratio greater than 4:1. However, in any case, the parts of the closure cap on the front and back sides of the carton are different in size, preferably corresponding to a ratio of 2:1 (front side to back side). Because of this proportion, each side of the closure cap forms an acute angle 7 with the front carton opening, rather than dividing at right angles from the adjacent carton surface on the front and back sides of the carton.

[0013] Cartons according to the invention can be printed in a single color or in multiple colors. The blisters are preferably arranged in one or more layers within the carton and are dimensioned precisely to the extent that the blisters fill the hollow space created within the carton. Furthermore, a cavity can be provided for accommodating a so-called insert slip with the drug for enclosed usage information. A desiccant may also be included within this carton according to the invention to protect the medication from moisture.

[0014]

Effects of the Invention The advantages of the carton according to the invention can be summarized as follows. Especially for elderly patients,
It is clear and closes on one side which is easier to handle, ensuring that the package is always opened from the "correct" side. The stability of the packaging is better, so that the carton remains perfectly intact even after several opening and closing operations. Usage information is easy to retrieve and return. It is also equipped with a blister. Immediately after opening the package, the medication is visible without the need to first remove and replace the blister. It has an attractive appearance.
