(71) Tuomo Halonen Oy, 37800 Toijala, Finland-Finland (FI) (72) Tuomo Halonen, Toijala, Finland-Finland (FI) (7U) Oy Heinänen Ab (5U) Method for manufacturing packaging boxes - Förfarande för fram-ställning av förpackningsaskar The present invention relates to a method of manufacturing packaging boxes, which method comprises forming a honeycomb package comprising a plurality of successive and parallel boxes, which can be divided into separate boxes if desired.

· *

Cellular packaging packages consisting of a large number of separate packaging units are generally known in packaging technology. Such packages are made, for example, of sheet-like plastic material by thermoforming. After the molding step, the packages are filled and covered with a uniform lid that extends over the entire package. The method is used especially for the packaging of liquids, foodstuffs, tablets and other separate articles.

The object of the present invention is to provide a method by which a honeycomb package can be manufactured without a molding step and in which packaging materials can thus be used, which would not be possible to mold using heat, compression, etc., e.g. cardboard. The invention is characterized in that successive and parallel box blanks are formed on a web of 57235 cartons or the like packaging material so that each blank has parts corresponding to the bottom and sides of the box, connecting parts as side extensions and folds between the parts, and the web is then bent into a package. wherein the boxes formed from the blanks are attached to each other via said joints.

If the package assembly according to the invention is finally divided into separate boxes, these boxes are in accordance with conventional packaging boxes formed by bending. However, such boxes have hitherto been made by bending blanks embossed from packaging material into boxes one at a time. After filling the boxes, each box is usually closed with a separate lid. In comparison, the method according to the invention is considerably more efficient and better suited for mass production. In the method, the formation of box blanks in a web of packaging material is carried out by stamping in a known manner, while leaving the blanks adhered to each other via connecting parts. Thus, in the next folding step, the blanks are formed into boxes which are still attached to each other via the connecting parts. The advantage of the invention is the considerably facilitated further processing of the boxes, whereby they are, for example, filled with a product or products to be packaged, possibly subjected to heat or the like, packed into larger units, transported at intermediate stages of trade and finally to consumers. In most cases, the package assembly is finally divided into separate boxes, but when the boxes are used, for example as germination trays, they can advantageously be handled in all stages as uniform packaging units.

The invention can be applied in such a way that a support ring or the like is connected to a package assembly comprising a plurality of parallel and successive packaging boxes, which surrounds each box so that the walls of the box rest on said support frame.

In addition to paperboard, other known raw materials for the production of packaging boxes can be used for the production of the boxes according to the invention, such as paper, metal foil, plastic, combinations thereof, etc. The possible lid lids and support rings can of course be made from corresponding raw materials.

The invention will now be described, by way of example, with reference to the accompanying drawings, in which 57235

Figure 1 shows box blanks made according to the invention.

Figure 2 shows finished boxes made from the box blanks of Figure 1.

Figure 3 shows a section along the line III-III in Figure 2,

Figure 4 shows packaging boxes made according to the invention filled with a product to be packaged and a lid.

Figure 5 shows another type of box blank and

Figure 6 shows a support frame to be connected to boxes made according to the invention.

According to the invention, a plurality of adjacent and successive box blanks 3 are formed on the paper web 2 shown in Fig. 1, comprising a box bottom part 4, side walls 5, folds 6 along which the blanks are bent into boxes, and connecting parts extending from side wall extensions. 'there are weaknesses 11 between which the blanks are attached to each other. The blanks 3 are stamped on the web 2 in a manner known per se; It is essential in the invention that a plurality of adjacent and successive blanks are formed in the web 2, which are then bent in a bending step into dry boxes 1 and 3 so that the boxes join through the connecting parts 7 into a honeycomb If desired, the packaging boxes 1 can be detached from the packaging assembly as separate units along the detachment points formed by the weaknesses 11. On the other hand, the packaging boxes 1, as well as the blanks 3, can be treated as arbitrarily large units comprising several adjacent and successive boxes or blanks, respectively.

When forming blanks 3 from the web 2, this can be done, for example, in one work step with one pressing stroke, whereby a row of blanks running across the web is formed. On the other hand, the blanks can be produced in stages, for example by first stamping the necessary cuts on the web, after which the folds 6 are pressed into place. After the formation of the boxes 1, gluing or other sealing, for example heat sealing, can be performed if desired. Furthermore, filling the box with the product to be packaged, closing with a lid 9, possibly frying or other handling can be flexibly connected to the manufacture of 57235 boxes. Figure 4 shows a packaging box cell filled with a product, which is also closed by a lid 9. Weakness points 12 are also formed in the lid 9 so that the boxes can be separated into separate units if desired. Figure 5 further shows a single box blank 3 with flange-like connecting parts 17, detached from the dough.

Figure 6 shows. shown a support ring 10 which can be connected, if desired, to support the box or box cell, for example by gluing or heat-sealing. The formed support frame 10 comprises slits 15 which can be folded along fold lines 16 so that the slits support the side walls 5 of the box. The support frame '10 can also be made of a paper web so as to form several adjacent and successive support frames which can then be separated into boxes 1 if desired. with these apart.

The invention is, of course, not limited to the examples shown, but its application may vary within the scope of the appended claims.

In this case, the shape of the boxes 1 to be manufactured can vary greatly and they can be, for example, square, rectangular, * polygonal, round, or any shape. Furthermore, the shape and number of connecting parts 7 may vary and the blanks 3 and the boxes 1, as well as the cover 9 and the support frame 10 ,. may be connected to each other, for example, by one connector on each side of the box.

Claims (1)

A claim for the production of packaging boxes (1), which method comprises forming a honeycomb package comprising a plurality of successive and parallel boxes, which can be divided into separate boxes if desired, characterized in that successive and parallel sheets of cardboard or similar packaging material are formed. box blanks (3) so that each blank has parts (4,5) corresponding to the bottom and sides of the box, connecting parts (7) extending to the sides and folds (6) between the parts, and that the web is then bent into a package in which the blanks the boxes (1) are attached to each other via said connecting parts.
