Packaging and method for manufacturing and filling

The invention relates to a package according to the preamble of claim 1. Such packages are mainly used in the pharmaceutical industry for packaging elongated objects such as, for example, ampoules, bottles or syringes. Box and packaging insert consist of flat material parts and are only glued immediately before the filling process.

In most conventional packaging, the packaging insert is wave-deformed and the elongated objects are placed parallel to the waves in the wave valleys. However, packaging inserts have also been known for a long time, in particular for packaging so-called double-pin ampoules (Doppelspiessampuls), in which the objects are cut in comb cuts transversely to the combs. Examples of such packaging inserts are described in FR-A-722114 or FR-A-2442191. However, the packages shown there are not suitable for use in high cycle packaging lines of the phases in which the entire package is manufactured immediately before the filling process.

It is therefore an object of the invention to provide a package of the type mentioned in the preamble, which is economically manufac- tured and filled, and which is distinguished by low material consumption. The packaging should thereby be as stable as possible and protect the packaged goods from external mechanical effects. According to the invention, this task is solved with a package comprising the features of claim 1.

Surprisingly, it has been found that rectangular boxes with insertion lids known per se can be used much more silently, when they are generally provided with triangular cross-sections, which hold the packaging goods in one row or in several rows. If the undercut is correspondingly designed, it is readily possible, even to place only a single comb in the box, to hold a row of objects.

Particularly high stability can be achieved when the packaging insert extends at the bottom over the entire width of the box and when it comprises lateral reinforcement strips which are glued or abutting the side walls parallel to the combs. In this way the side walls parallel to the combs are also stiffened, on which, as a result of the relative location of the objects, as little deflection as possible should occur.

Further advantages can be achieved in this case if the side walls glued with the reinforcement strips extend at right angles to the side wall with the insert cover and if a folding dust flap is provided on these side walls. In such an arrangement there is also no danger of bending or damaging the side walls when the packaging is frequently closed and opened.

Depending on the configuration of the packaging goods 25, it can be particularly advantageous if the adjacent partial cut-outs in the two side walls of the comb comprise different profile shapes. In this way, the objects can be stabilized not only transversely, but also parallel to their length dimension.

The packaging of at least two rows of objects is possible with three or four parallel combs. In the three-comb arrangement, the cut-outs in the outer combs must be displaced such that the central comb serves to hold the two rows together. In the four-comb configuration, the axes of the elongated objects in the two rows may run coaxially or offset.

1008589 3

In some cases, two rows of objects can also be held with only two parallel combs.

The side walls of a comb may be inclined at an angle of less than 45 degrees, preferably from 10 to 35 degrees, relative to each other. This provides relatively slender and pressure-resistant combs. The side walls of a comb preferably form an isosceles triangle in cross section. In some cases, however, an unequal stance may also be possible.

A particularly advantageous processing in the packaging line can be achieved if the comb or combs respectively extend at right angles to the side wall with the insert lid. Preferably, several combs extend at a right angle to the side wall with the insert lid over approximately the total length of the package.

A particularly advantageous warranty function on the packaging can be achieved if an insertion tongue 2 0 is glued in the side wall parallel to the insertion lid with the insertion lid and glued to the insertion lid, and if the insertion tongue is placed between the end face of the two parallel combs is. In this way the two combs form a point of support which supports the side wall against the pressing forces.

The top of the individual combs is preferably arranged at a distance from the closed insert cover. On the one hand, space is thus provided for the insertion of package inserts, etc. On the other hand, however, a pressure on the insert cover does not immediately lead to a disturbance and thus to a load on the individual combs.

The packaging insert for the above-described packaging preferably consists of cardboard. In the same way as the flat blank for the box, the flat shape blank must also be provided with folding lines, so that it can be erected in the packaging line into the actual packaging insert. The blanks are pre-cut 1008589 4. The folds for the tops of the combs are preferably formed by a score. These grooves allow a correct bending of the blank, but practically do not cause weakening. On the other hand, the 5 folding edges for the underside of the side walls of the comb facing towards the bottom can easily be formed by a perforation. This perforation allows a particularly light and resistance-free bending. A weakening is not to be feared, since these undersides immediately adjoin a material section glued to the bottom.

The invention also relates to a method for manufacturing and filling the aforesaid packaging, which is characterized by the features in claim 12. With such a method, high packaging capacities can be achieved at 90 or more strokes per minute, with a packaging being manufactured and filled with each stroke. The individual workstations can be easily exchanged or converted, so that a format change is possible within a few minutes.

Examples of embodiments of the invention are shown in the drawings and are described in more detail below. In the drawing: figure 1 shows a top view on a flat blank 25 for a box, figure 2 shows a top view on a flat molding plate, figure 3 shows a perspective view of a packaging that is ready, manufactured with the blankes 30 according to figures 1 and 2, figure 3a shows a detail view of a comb from figure 3, figure 4 a cross-section through the packaging according to figure 3, figure 5 a top view of an alternative embodiment with a single comb, 1008589 Figure 6 a top view of an alternative embodiment with four combs, figure 7 shows a top view of a packaging insert with three combs, figure 8 shows a side view of a comb with double undercuts, figure 9 shows a schematic representation of a packaging line for manufacturing and filling the package, and figure 10 shows a top view of an alternative embodiment of a flat shape blank.

Figure 1 shows a blank 1 already known in the prior art for a cardboard box with a rectangular bottom 4, with longitudinal walls 5, 5 'and with transverse side walls 6, 6'. An insert cover 7 with an insert cover 8 connects to side wall 5. Likewise, the side walls 6, 6 'are provided with dust flaps 9, 9'. Glue lips 11 are applied to the side walls 5, 5 ', which are later joined to the side walls 6, 6'. On the longitudinal side wall 5 'a pressing tongue 10 is arranged in the middle, which is bounded by a planned break line 13. The individual parts are separated from each other by prepared folding lines 12, which are indicated by dashed-dotted lines in the drawing.

Figure 2 shows a likewise flat blank 14 of cardboard, from which the packaging insert is manufactured. The depicted shape blank is intended to form two parallel combs, each of which comprises a side wall 15, 15 '. In each comb, large cutouts 18 and small cutouts 18 'are arranged alternately. In each side wall, each cut-out forms a partial cut-out 19 resp. 19 '. The partial cutouts have a different configuration, which is adapted to the object to be picked up. An undercut 26 for clamping an object is provided in at least one partial cut-out. For mounting the packaging insert against the bottom 4 of the box, bottom walls 17, 17 'respectively.

1 008 589 6 20 provided. The shaping blank is laterally closed by a reinforcing strip 16, 16 '. The individual parts are also separated from each other by folding lines 12.

Figure 3 shows a packaging 1 manufactured from the blank 2 for the box and the molding blank 14 according to Figures 1 and 2. At the box 3 the side walls 5, 5 ', 6, 6' are erected and are connected with each other via the glue lips 11 glued. The fabric flaps 9, 9 'are still folded out and the insert flap 8 on the insert cover 7 is angled.

The packaging insert 21 is also erected and glued to the bottom of the box 3. The reinforcement strips 16, 16 'run parallel to the side walls 6, 6' and 15, respectively. glued to the glue lips 11 therebetween, so that relatively bend-resistant side walls are formed, which run parallel to the combs 22, 22 '. Alternatively, however, these reinforcement strips would also only be against the side walls 6, 6 'and the abutment lips 11 can abut. This also results in a total reinforcement. The combs always form a comb top 23, which is interrupted in each case by the cuts 18, 18 '.

Figure 3a shows a side view of a separate cut-out 18 ', with the undercut 26 in the side wall 15' behind it being clearly visible. The packaging insert shown is intended to receive ampoules, which are pressed into the cut-outs from above with light pressure. After filling, the dust flaps 9, 9 'are folded inwards and the insert cover 7 is closed and glued to the insert flap 8 with the inside of the insertion tongue 10. The cover can be opened again by breaking out the pressing tongue 10 from the side wall 5 '. The pressing tongue is placed between the ends of the two combs, so that the side wall is well supported.

Figure 4 shows a cross-section through the package according to Figure 3 with an ampoule designated as a contour 24. The ampoule is snapped into the combs 22, 22 'at its cylindrical body and at the 1008589 7 neck. The cut-outs in the combs are arranged alternately, so that the ampoules are alternately mirrored side by side. As can be seen in figure 4, the ampoules are kept at a distance from the outer walls of the package and are thus well protected against mechanical effects. The side walls 15, 15 'together with the bottom 4 of the box form an isosceles triangle with an acute angle, which is relatively resistant to pressure on the insert cover 7.

Figure 5 shows an alternative embodiment of a package intended for cylindrical bottles 25. The packaging insert has only a single comb 22 which runs parallel to the hinge location of the insert cover 7. The cut-outs 18 in the comb are arranged in such a way that each bottle 25 is immediately held under the lid at its opening.

A further exemplary embodiment of a package with four parallel combs 22a, 22b, 22c, 22d is shown in figure 6. In accordance with the exemplary embodiment of Figure 3, the ampoule cut-outs 18 are formed with two parallel rows of ampoules lying side by side. The ampoules are aligned in each row. However, the tips of the ampoules of the two rows are facing each other. The center lines 27 of 25 the ampoules resp. however, the cut-outs in the two rows are staggered such that the tips of the ampoules overlap each other.

Such a zipper-shaped arrangement of the tips of the ampoules is also provided with the packaging insert piece 21 according to Figure 7. However, only three combs 22a, 22b, 22c are provided here, the outer combs 22a and 22c each carrying the body of an ampoule, while the middle comb 22b simultaneously receives the tips of the two rows of ampoules. Accordingly, the outer combs have only large cutouts 18 and the middle comb 22b has only small cutouts 18 '.

Figure 8 schematically shows a comb 22 for receiving two superimposed surfaces with ampoules 24, 24 '. The cutouts 18 are provided for this purpose with two undercuts 26, 26 ', which are arranged on different surfaces 5.

Figure 9 shows on the basis of a schematically shown packaging machine how the packaging according to the invention can be manufactured and filled in a particularly simple and rational manner. The packaging machine 10 has several workstations one behind the other, which are arranged along a conveying means, for instance a vacuum conveyor belt 38. From a magazine 28, blanks 2 for a box can be taken and taken to a erecting station 29, where they are erected and glued into a box 3. In the same stroke, molding blanks 9 are taken from a further warehouse and molded into packaging inserts 21 at a molding station 31 and subsequently glued into the finished boxes at a gluing station 32.

The packages prepared in this way then pass through two insertion stations 33, 33 ', in which two packages 1 are simultaneously filled with ampoules 24. At a control station 34 it is determined whether each package is filled.

The filled but still open packages 25 then pass through an addition station 35, in which a package insert 39 is also placed from above. Finally, the packages pass through a closing station 36, where the dust flaps are folded. At the same time, the insert cover 7 is closed and glued. At an ejection station 37, the filled packages are ejected in arrow direction b at a right angle to arrow direction a of the transport means.

Figure 10 finally shows a top plan view of a flat shape plan analogous to figure 2. The formed shape blank is also intended to form two parallel combs, each comprising a side wall 15, 15 '. However, each comb includes only a single 1008589 9 cut-out 18, 18 'to receive a single ampoule. The middle bottom wall 20 is relatively narrow and reinforcing strips 16, 16 'adjoin the outer bottom walls 17, 17'. The folding lines, which lie in the plane of the packaging bottom, are designed as perforations 12/40. On the other hand, the two folding lines, which later form the comb top, are designed as grooves 12/41.
