Definitions

• the invention relates to a packaging system with tablet-shaped objects, in particular break-sensitive tablets, with a polygonal outer packaging formed from a folding blank made of cardboard or the like, and with foil bags arranged in the outer packaging, in each of which at least one tablet-shaped object is accommodated.
• Detergent and / or cleaning agent in tablet form e.g. Due to their hygroscopic properties, they require additional protection against moisture and are generally packed in plastic bags.
• Such a foil bag is e.g. known from DE 295 09 593 U1.
• tablets (single or multiple wrapping) wrapped in such foil bags are loosely packed in a packaging container, such as a package, carrying package, drum or the like, which in principle represents a sufficiently stable outer packaging or outer packaging during storage and transport.
• the stability relates to the required crush resistance of the containers under pressure and weight loads within a pallet group.
• detergent tablets of this type are break-sensitive products which are generally stressed during the filling process and during transport in such a way that edge breakage, breakage and abrasion cannot be avoided even with normal, stable outer packaging. Against this, the tablet is also not protected by the foil pouch, which offers only a slight additional protective effect against impact stress and during transport.
• a generic packaging in which the foil bags are arranged in the outer packaging in a sorted manner with longitudinal seams oriented parallel to one another, the length of the foil bags being greater than the distance between the side walls of the foil bags parallel to the transverse seams Outer packaging, such that at least one end region of the film bags lies resiliently bent in the outer packaging and that at least the side walls of the outer packaging parallel to the longitudinal seams of the film bags are equipped with wall reinforcements.
• the sorted arrangement of the film bags in the packaging absorbs shock loads parallel to the longitudinal seam in the film bags relatively well, these shock loads are partially absorbed by the bent fins (transverse seams) of the film bag.
• the film bags are also designed to be longer than the relevant packaging length (distance of the side walls of the outer packaging parallel to the transverse seams of the film bags), at least one of the two fins of the respective film bag is bent over when it is inserted into the outer packaging, so that the fin resiliently lies in the outer packaging , which can dampen shocks without causing damage to the tablet-shaped products. Shock loads parallel in the longitudinal direction of the foil pouch cannot damage the tablets. Shock loads in the transverse direction, ie parallel to the transverse seams, are absorbed by the special design of the outer packaging with wall reinforcements in the corresponding side walls thereof.
• a tablet preferably a water-soluble detergent tablet

Furthermore, the influence of the type of gluing was investigated and it was found that in the packaging system according to the invention continuous gluing over the height of the Side wall is advantageous over an adhesive bond interrupted over the height.
