AI Technical Summary

Technical Problem

Cuboidal folding cartons suffer from instability and damage during transport and stacking due to weak handles and inadequate support structures, often requiring additional reinforcement.

Method used

A cuboidal folding carton design featuring a left and right side wall with recesses as handles, an upper inner flap with three sections, and a second recess at the third folding edge, allowing the inner flap to form a support edge orthogonal to the side wall, enhancing stability and stackability by distributing weight forces across a triangular shape.

Benefits of technology

The design significantly increases the carton's stability by distributing weight forces, preventing handle tearing and improving stackability, while also enhancing carrying comfort through reinforced grip surfaces.

Abstract

A cuboid folding carton (1) with a front wall (5) and a rear wall (6) which are connected to each other by a left side wall (7) and a right side wall (8) to form a wall (9) surrounding an interior space (3), wherein the left side wall (7) and the right side wall (8) each have a first recess (31) designed as a handle (30), wherein an upper inner flap (10) is hinged to at least one of the side walls (7, 8) along a first fold line (11), characterized in that the inner flap (10) comprises a second fold line (12) and a third fold line (13), wherein a first section (21) of the inner flap (10) is located between the first fold line (11) and the second fold line (12), a second section (22) is located between the second fold line (12) and the third fold line (13), and a third section (23) is located between the third fold edge (13) and a free end (14) of the inner flap (10) extends,wherein by folding the inner flap (10) at the first fold line (11) the first section (21) forms a support edge (20) extending at least approximately orthogonally to the at least one side wall (7, 8), wherein the second section (22) is folded at the second fold line (12) by more than 90° relative to a lid plane (42) into the interior (3), wherein the folding carton (1) comprises a second recess (24) which is provided in the inner flap (10) at the level of the third fold line (13).
