European Patent, Norway, Finland, Denmark, USSR, Canada, USA, 'a blank of packaging container' (as the divisional patent application num.515.262 invention, filed 26 August 1982) countries

摘要

Packing container blanks for gable-top packages are cut out of a material web which, up to now, has caused an appreciable amount of waste material, since the edges of the blanks are irregular and cannot be "dovetailed" into one another. A packing container blank is provided with partly straight, parallel lateral edges (11,12), and partly transverse edges (11,12) which are indented according to a regular pattern which is repeated over the width of the blank. As a result of the indentations, the edges of the blanks too can be formed without wastage.
