Abstract

The present invention shows and describes a composite material package, in particular a beverage carton package for liquid food, which composite material package is at least partly constructed from a package laminate and has a package base, with corners A package bottom and a package gable top of a package bottom capable of being formed on a folding mandrel of a packaging machine so that a partially formed package can be filled through its top region and closed to form the the above packaging. And the present invention also shows and describes package laminates and packaging sleeve blanks for making composite packages of this type. In order to improve producibility and quality, it is provided that a vertical auxiliary edge remnant for the folding mandrel is formed on the package base body in a seamlessly contiguous manner in the region above the bottom corner, said auxiliary The height of the edge stubs is each less than a third of the overall height of the packaging.

Description

technical field

[0001] The present invention relates to a composite material package, in particular a beverage carton package for liquid food, said composite material package consisting at least in part of a package laminate, said composite material package having: a package Base body, package bottom with corners and package gable top, wherein the package bottom is formed on the folding mandrel of the packaging machine so that the partially formed package can be filled and closed via its top area to form a package.

[0002] The present invention also relates to a package laminate having at least one paperboard carrier layer and at least one polymer layer having a plurality of creases machined into the material to predefine package fold lines for forming package edges.

[0003] Finally, the invention relates to a packaging sleeve blank consisting of a packaging laminate having at least one paperboard carrier layer and at least one polymer layer and having a plurality of crease...

Embodiment Construction

[0033] figure 1 The embodiment of a composite package P according to the invention shown in , is formed by a package base 1 , a package bottom 2 closing said package base and a package gable 3 forming the top of the package. All three parts are formed from the same packaging material through a forming-folding process. Thus, the package bottom 2 is formed via the package folding line 8 on the folding mandrel of the packaging machine and sealed by means of ultrasound (alternatively eg hot air, adhesives etc. are conceivable). The bottom-sealed semi-finished package product is then filled with the required package product via the open top area, and then a package gable 3 inclined forwards with respect to the package base 1 is formed by a further package fold line 8, The package gable 3 seals the package by means of an ultrasonically welded transverse sealing seam 12 . The excess packaging material part produced during the forming of the package gable 3 forms a package ear 13 wh...
