Paper Pouch Embossed Lines for Machine Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging machines designed for foil bags are not suitable for reliably opening and filling bag-shaped packaging made of paper or cardboard, as conventional paper or cardboard bags cannot be reliably opened by these machines.
Innovation Solution
A bag-shaped packaging made of paper or cardboard with embossing lines that facilitate easier bending and opening, allowing the side surfaces to be machine-bent and the bag opening to be reliably enlarged for mechanical filling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional packaging machines designed for film pouches are used to fill paper or cardboard bags, then the existing infrastructure can be utilized, but the paper or cardboard bags cannot be reliably opened by these machines
Solution Approach 1:
The patent applies local quality by creating embossed lines at specific locations on the side surfaces of the bag. These embossed lines concentrate the bending effect to localized areas, allowing the bag opening to be reliably enlarged at the gripping points while maintaining the overall structural integrity of the paper or cardboard material.
Solution Approach 2:
The patent changes the physical parameter of the side surfaces by embossing lines into them. This embossing modifies the local flexibility and bending characteristics of the paper or cardboard, enabling the material to respond predictably to the mechanical action of the packaging machine grippers without requiring machine redesign.
2Ease of manufacture
If paper or cardboard material is used for bag-shaped packaging, then recyclability is improved, but the material cannot be reliably opened by existing packaging machines
Solution Approach 1:
The embossed lines are created during the manufacturing process as a preliminary action. This pre-embossing prepares the paper or cardboard material in advance to be easily opened by standard packaging machines, eliminating the need to modify the machines while preserving the recyclable material choice.
3Productivity
If side surfaces are pressed together to enlarge the bag opening, then the bag can be opened for filling, but creases may form that impair the appearance of the packaging
Solution Approach 1:
The embossed lines concentrate the deformation to specific localized areas during the opening process. This ensures that bending and creasing occur only at the embossed line locations rather than across the entire side surface, preserving the overall appearance quality of the packaging while enabling rapid opening.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the use of packaging machines suitable for foil bags to fill and close bag-shaped packaging made of paper or cardboard, improving the recyclability and efficiency of the packaging process.
Implementation Method 1
The embossed lines facilitate the bending of the material, so that where the embossed lines are located, the material can be bent more easily than in areas farther away from the embossed line(s)

AI summary
The present invention relates to a pouch-shaped package formed by folding and gluing a paper or cardboard blank, with two side surfaces that are joined together in the region of a bottom edge of each side surface to form a bottom area, wherein the two side surfaces each have two side edges via which they are directly connected to each other, wherein the two side surfaces define a closable bag opening in an opening area of the side surfaces opposite the bottom edge, and wherein the two side surfaces each have at least two embossed lines which are embossed into the respective side surface, along which the material of the paper or cardboard blank is not folded. The invention further relates to a method for the machine filling of such a pouch-shaped package.
