DESCRIPTION:
BRIEF SUMMARY
PRIOR ART
The invention is based on a one-piece blank for a folding box for packaging such articles as ampules, small bottles, vials or the like. In a folding box of the present Applicant, known from German Patent Disclosure DE 43 09 036 A1, now U.S. Pat. No. 5,402,889, it is possible to make the blank for the folding boxes in one piece. At the folding box factory, this blank can be folded, glued and flattened. The folding boxes laid flat are then shipped in stacks to the packing plant, where taking up little space they are kept on hand and then erected as needed with a cartoning machine, equipped with the articles to be packed, and closed. A disadvantage of this otherwise satisfactory folding box is that for gluing and folding on conventional gluing and folding machines, it requires multiple passes, since the gluing and folding machine allows only a certain number of folding operations per gluing pass. This not only means major effort and expense for manipulation but also makes for a relatively low yield in such machines.
U.S. Pat. No. 4,160,502 also discloses a folding box, whose insert extends at right angles to the long sides of the side walls. German utility model DE 92 14 914 U1 shows a folding box with closure flaps folded over onto one another and inseparably joined together; the flaps have a perforation with which a lid part can be folded open from a bottom part.
ADVANTAGES OF THE INVENTION
The one-piece blank according to the invention for a folding box has the advantage over the prior art that the folding box made from the blank can be produced with only a few folding operations, so that all the folding operations can be done during one pass for gluing on conventional gluing and folding machines. The result is a short production time for the folding box and low expense for manipulation, so that the folding box can be produced especially economically.
Other advantages and advantageous features of the one-piece blank according to the invention for a folding box will become apparent from the claims and the description. By varying the dimensions of the tabs that form the partition and are joined to the curtain walls, the compartment, for instance for a package leaflet, can be adapted to the size of the package leaflet. An especially advantageous opening and closure and a good overview of the articles located in the folding box can be attained if the upper part of the tube is embodied as capable of being folded open along a perforation line.
BRIEF DESCRIPTION OF THE DRAWINGS
One exemplary embodiment of the invention is shown in the drawing and will be described in further detail in the ensuing description.

DESCRIPTION OF THE EXEMPLARY EMBODIMENT
The parallelepiped folding box (FIG. 1), made of a stiff packaging material, preferably cardboard, has a tubular body 10 with two long side walls 11, 12 parallel to one another and two short side walls 13, 14 parallel to one another. One short side wall 14 is glued on its inner surface to a trapezoidal longitudinal gluing flap 15 pivotably joined to the long side wall 11. The end faces of the body 10 on the bottom and top sides are closable by means of closure flaps 16-23 that are pivotably joined to the side walls 11-14, folded over into the respective end faces, and glued together.
FIGS. 2 and 3 will now be described: To fold the top part 25 open from the bottom part 26, the folding box is equipped with a perforation 27. The perforation 27 will be described in further detail hereinafter. An insert 30 with openings 31 for form-fitting reception of articles such as ampules, small bottle
