Cardboard Packaging Insert With Locking Tabs for Built-In Compartments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging inserts, particularly those made of plastic, are costly to produce due to the need for new tools for design changes and raise sustainability concerns, while cardboard inserts face challenges in machine production and require separate plastic partitions.
Innovation Solution
A packaging insert design featuring locking tabs and internal side walls that divide the receiving space into compartments, made from environmentally friendly materials like paper or cardboard, eliminating the need for separate partitions and allowing machine production in various embodiments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plastic packaging inserts are used, then production cost is reduced and durability is improved, but sustainability is worsened and adaptability to design changes is reduced
Solution Approach 1:
The packaging insert is divided into modular components: a base structure with receiving openings and detachable container elements. This segmentation allows different container configurations to be used with the same base, enabling design adaptability while maintaining production efficiency. The modular design lets manufacturers switch between different container types without retooling the entire system.
2Adaptability or versatility
If cardboard packaging inserts are used, then sustainability is improved, but machine production capability is worsened
Solution Approach 1:
The cardboard packaging insert features pre-assembled structural elements with predetermined folding lines and attachment points. The base structure is pre-formed with receiving openings, and containers are designed with pre-attached connection elements. This preliminary preparation enables automated assembly machines to efficiently join components without complex manual intervention, overcoming the machine production challenges of traditional cardboard inserts.
3Device complexity
If separate plastic partitions are added to cardboard inserts, then compartmentalization is improved, but material usage is worsened and assembly complexity is increased
Solution Approach 1:
The partition walls are integrated directly into the container structures rather than being separate elements. Each container includes its own partition walls formed as part of the container body, eliminating the need for additional standalone partition components. This merging of functions reduces material consumption and simplifies assembly, as partitions are already positioned and attached when containers are placed in the base structure.

AI summary
The present invention relates to a packaging insert (10) comprising at least one bottom wall (12), at least one top wall (14) with at least two receiving openings (46) for receiving goods, and side walls (16, 18) connecting the bottom and top walls (12, 14) to form a receiving space (20), wherein the receiving space (20) can be subdivided into several sub-spaces (22). The partial spaces (22) are each bounded by means of locking tabs (24, 26) hinged to the lid wall (14) via at least one bending line (90, 92) and inner side walls (38, 42) arranged within the receiving space (20), wherein the locking tabs (24, 26) are designed to engage with locking openings (32) formed in the bottom wall (12) and the bending line (90, 92) between lid wall (14) and locking tab (24, 26) limits the extent of the receiving opening (46) in this area.The inner side walls (38, 42) are designed as partial elements of an inner partition wall (34). The invention further relates to a blank (100) made of paper, cardboard or similar materials for the production of a packaging insert (10).
