Folding box blanksi

Folding boxes made of cardboard have been known for a long time in a wide variety of shapes, designs and sizes and are used for a wide variety of packaging purposes.

However, these cardboard boxes have the significant disadvantages that they are only partially dimensionally stable and sensitive against moisture and are opaque. Above all, the last-mentioned deficiency forms in many today Cases an obstacle in the sale of certain goods, because the consumer likes to judge the packaged goods visually would like to. For this reason, deep-drawn containers, bags and others made of plastic are on the Market, which make it possible to inspect the goods without having to unpack them.

Recently, folding boxes for packaging purposes have also been used to avoid the disadvantages mentioned used made of rigid plastic films or -Plates are made. In order to be able to erect the flat blanks better in the box shape,

therefore already proposed to subject the bending points to a pre-bending or grooving. If also this made it possible to achieve a certain improvement in the manual erection of the blanks, so processing on conventional packaging machines for cardboard boxes has not been possible until now. Rather, it was still necessary to packing machines a machine for erecting the Pre-cut blanks, which means a considerable amount of work additional technical effort had to be accepted.

The mentioned shortcomings in the manufacture and use of the known folding boxes are now in accordance with the innovation Eliminated by cut-to-size boxes with grooves at the bending points made of rigid plastic foils or plates, which are characterized in that the continuous grooves 1 are pressed out of the material are, the cross-section of the material thickness decreases towards the middle of the grooves and at the deepest Place in the longitudinal direction perforations in the form of adjacent incisions 2 are attached.

Such folding box blanks can be, because. " the perforations parts in the material are taken out and through the grooves in their special shape In addition, a material weakening was created, slightly straighten up at the bending points and to process*.

The manual erection is much easier and quicker to carry out, because the forces that a Bring back springing after the bending process are greatly reduced.

Above all, however, the new blanks have become part of the processing during machine erection Tried and tested in known packaging machines for cardboard boxes. The technical progress that makes that Upstream connection, which makes complex erecting machines superfluous, is particularly evident in the more efficient one Manufacture of the aforementioned folding boxes.

The length and width of the incisions, as well as their distance from one another, depends on the. Stiffness of the material and the thickness of the blanks or the depth of the grooves. These variables are so coordinated that that the requirement of easy erectability is satisfied. With film thicknesses as they are for commercial packaging is chosen, for example »the length of the incisions is 1 to 5 mm»

The choice of material thickness for the blanks largely depends on the size of the desired packaging container. So you come with for smaller boxes. thinner material thicknesses, while larger containers must have a corresponding thickness. Folding boxes, as they are used for commercial goods, have a strength that depends on the type of plastic ranges from 0.05 to 1.00 mm.

On the other hand, the depth of the grooves depends on the strength of the foils or plates, the size of the incisions and their distance from one another, as well as the one used Matched material type. With common container sizes it is at the thinnest points of the grooves

about 30 to 70% of the material thickness of the blanks. In special cases, however, these values can also be used be exceeded or undercut.

The grooves can basically have differently shaped cross-sections in their design. Next to triangular, curved shapes (Fig. 2) are preferred because of the simpler manufacturing technique.

As a material for the blanks, all those plastics come into question, which due to their stiffness give finished containers sufficient stability. Stability is understood to mean the Resistance of the container to pressure without causing permanent deformation. Next to ' Films and sheets made from polyolefins, polyamides, polyvinyl chloride, polystyrene and polymethacrylic acid esters acetate-based ones are also used.

In order to meet consumer demands, the blanks are preferably made of transparent, above all clear plastics. Plasticizer-free polyvinyl chloride has proven to be special in practice proved suitable. For some uses it is. it. however, it is not absolutely necessary to make the packaging containers completely transparent. To certain To achieve optical effects, there is also the possibility of using colored plastics. Another. Variants in this regard also result from the fact that the blanks are completely or partially printed and / or have embossings. To get an appropriate
