BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a packaging component for accommodating elongated articles, in particular ampoules.

0002

BACKGROUND OF THE INVENTION These types of packaging components form durable box inserts, protect the items to be packaged from blows and impacts, and avoid contact with each other. These types of packaging inserts are referred to as corrugated components.

[0003] Most known packaging components contain elongated articles in corrugations between individual chambers, as disclosed for example in Swiss patent CH-A-263453 or French patent FR-A-1049050. will be introduced. Therefore, after opening the package, the ampoules are not protected over their entire circumference and axial stability of the ampoule is not achieved. This is disadvantageous because when the box lid is opened, individual ampoules can fall out in different directions depending on the nature of the packaging.

[0004] It is therefore an object of the present invention to create a packaging component of the type mentioned above, which protects elongate articles over their entire outer diameter and at the same time provides longitudinal stabilization. Also, their production and filling should be as simple as possible in order to adapt the packaging components to automatic packaging lines. This object is solved by a packaging component having the features of patent claim 1 according to the invention. Depending on the nature of the item, fixed components are placed at both ends of the chamber or only at one end. Thereby, the chamber opening can be closed in the simplest manner without additional parts or gluing operations. The manufacturing of fixing the components takes place integrally with the carrier sheet. The necessary folding operations can be automated in the packaging line by relatively simple means. Items packaged in this way are protected in general and after removing or opening the outer packaging and will not fall out of the chamber when held in a vertical position. The outer packaging may be, for example, a separate box, shrink foil, as disclosed in FR-A-1049050.
) or form part of the carrier sheet.

[0005]

A particularly advantageous fastening of the article is obtained if the carrier sheet projects beyond the forming sheet on at least one side and the fastening component is a bendable fastening strip, which A fold disposed in and extending over the plurality of chambers at least partially closes the opening. The extension of the carrier sheet by such a fastening strip forms a kind of impact protection in the longitudinal direction. Fixing strips of this type can be placed on both sides of the chamber. If the article has a part exiting the chamber, such as the tip of an ampoule, the fixing strip and/or opening of the fold is placed in the opening area of each chamber. These openings extend beyond the folded edge between the fixing strip and the bend, the bend being directed towards the carrier sheet. The fixing strip is thereby tilted relative to the carrier sheet and the tip of the ampoule is held within the opening. In this way, the relatively complex tip of the ampoule is well protected. The fixing component is relatively simple to form, cutting out a fixing strap from the formed sheet that can be folded away from the original limiting wall towards the inside of the chamber at least at one end of the chamber. This step also makes it possible to close the chamber opening and add stiffness to the chamber cross-section. The fixation strap may be formed by a notch running parallel to the rim of the chamber at one end of the chamber.

In many cases it is practical to cut securing straps from the forming sheet at each end of the chamber. If an ampoule with a generally cylindrical ampoule body and an ampoule tip forms the contents of the package, the securing strap in the folded position forms a support bed for the tip at one end of the chamber. The tip of the ampoule thereby rests on the folding strap, which holds the ampoule body firmly in the longitudinal direction. Further advantages are achieved if the chamber is cut out at one end adjacent to the fastening strap. This allows the contents of the package to be clearly checked visually from the outside and, if necessary, the label can be read without removing the ampoule from the chamber. Of course, suitable cutouts can be placed in any part of the chamber. At the same time the cutouts can give decorative features.

It is particularly advantageous if the chamber has a polygonal shape with at least five corners. In this way articles with a circular cross section can be held well and at the same time the rigidity of the chamber can also be created. Chambers with particular advantages have a hexagonal cross-section, but may also have an octagonal shape.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The packaging component according to FIG. 1 basically has a carrier sheet 2 and a forming sheet 2 attached thereto. These sheets consist of cardboard, plastic or a laminate of different materials. The forming sheet 3 has already been folded to form a bend and is placed on or bonded to the carrier sheet. Parallel adjacent prismatic chambers 4 are thereby formed, which chambers 4 have openings 5, 5' in their end faces. In order to form a hexagonal chamber shape from a rectangular chamber in this embodiment, the side walls of the chamber already have bend lines 13 . Also conceivable are chambers 4 with round and wavy shapes without angles.

[0009] The deformation of the folded sheet and the joining of the folded sheet and the carrier sheet are carried out subsequent to the previous working steps, and different application methods can be used. For example, it is possible to process separate sheets. However, continuous production can be envisaged, with the carrier sheet and the forming sheet being pulled off the rollers and the individual chambers 4 being manufactured in succession. The material strips are then separated into separate sheets.

A carrier sheet 2 extends outwardly across the width of the forming sheet 3. The fastening strip 7 and the bend 8 join directly on this extension in the same plane. Again, a folding line 9 is arranged between the bending section 8, the fixing strip 7 and the extension 6. An opening 10 is cut out in the axial extension of the individual chamber 4, which in this embodiment extends beyond the fastening strip 7 onto the bent section 8. However, the shape and arrangement of these openings is highly dependent on the item that is to be secured within the chamber 4.

Furthermore, a cut is formed at the rear end of the chamber 4 running parallel to the outer edge. A fixing strap 11 is formed from that part of the forming sheet 3 in each chamber. Preferably, these cuts 12 are made before deforming the formed sheet.

FIG. 2 shows the packaging component according to FIG. 1 after the ampoule 1 has been inserted. Prior to the filling operation, a force is applied to the top surface of the chamber 4 in the direction of arrow a, bending the side walls of the chamber outward along the fold line 13, giving the chamber a hexagonal honeycomb shape. Of course, the side walls of the chamber 4 can also be bent at a number of points so that the chamber has an approximately circular shape.

[0013] Before filling, the bending part 8 is further bent over the fixing strip 7 and then the fixing strip is folded towards the opening of the chamber. This raises the ramp-forming structure as shown in FIG. 2, with the bend 8 pointing towards the extension 6 and partially closing the opening 5.

[0014] The opening 10 forms a mouth for receiving the ampoule tip 14, which is protected by this arrangement. Since the hexagonal chamber tends to return to the rectangular shape shown in FIG. 1, the ampoule is held by the chamber walls in tension so that the ampoule cannot rotate about its axis. After filling the chamber, fix the strap 11 in Figure 3.
Fold it toward the center of the chamber as shown. The fixing strap 11 thus forms a fixation within the chamber opening 5' and prevents the ampoule from slipping out to the rear. Ampules or other elongate items, such as technical equipment as the case may be, can be protected on all sides in this way and packaged in a simple manner.

[0015] Of course, the fastening components of the chamber opening may also be formed in entirely different ways. For example, it is possible to form the bent portion 8 to have a width that completely closes the opening 5. FIG. 4 shows an embodiment in which the bending portion 8 is not aligned towards the extension 6 but is aligned away from the extension. The fixing strip 7 is thereby arranged parallel to the plane of the extension 6. On the other hand, however, the fixing strip can be shaped in such a way that it forms a protective chamber that is essentially closed from all sides for the tip of the ampoule. For this purpose, a wall must be added between the extension 6 and the fastening strip 7 with a width approximately corresponding to the width of the bend 8.

FIG. 5 shows one embodiment of a packaging component in which the fixed components at both ends of the chamber are constructed from forming sheets. 3
The three chambers 4a, 4b and 4c are shown in their different stages of deformation. The carrier sheet 2 has the same width as the forming sheet 3. The package contents here are an ampoule 1 which likewise has an ampoule tip 14 .

The chamber 4a has a cross section substantially similar to the original shape as shown in FIG. Cut 12 at the rear end of the chamber
form the fixing strap 11. The cut 12' is arranged to have a greater distance from the outer edge than the cut 12. However, it also forms a kind of fastening strap that also acts as a support floor 15.

The chamber 4b has already been transformed into a hexagonal cross section along the fold line 13 on the side surface. The support bed 15 must be folded inward before the ampoule is inserted into this type of chamber. The ampoule 1 can then be inserted from the rear, with its tip 14 resting on the support bed 15. At the same time, the support bed forms a mechanical stop for the shoulder of the ampoule 1. This situation is shown in the case of chamber 4c. Only its fixing strap 11 remains folded inward to support the ampoule 1 at its base. Also in this embodiment the ampoule tip 14 is suitably supported.

In the embodiment according to FIG. 6, fastening straps 11 and 11' are likewise shown at both ends of the chamber 4. Here the contents of the package are not ampules but closure caps 18
The bottle 17 has a substantially cylindrical shape. Adjacent to the fixing strap 11' is a cutout 16 extending the width of the trapezoidal shape. Of course, the cutout can have other shapes, and the uniform shape is
adjacent to. On the one hand, the cutout facilitates the removal of the bottle and facilitates checking the contents of the package. Of course similar cutouts can be applied to other embodiments.
