Cardboard Packaging Container With Integrated Carrying Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cardboard packaging containers with plastic carrying straps and metal rivets are difficult to recycle due to the intimate connection between materials, leading to ecological concerns and increased disposal complexity.
Innovation Solution
A packaging container design featuring a carrying strap integrated with the lid flap, defined by perforation and cutting lines, eliminates the need for separate plastic straps and metal rivets, ensuring the container is made entirely of recyclable materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If plastic carrying straps with metal rivets are attached to cardboard packaging, then the packaging can be easily carried and handled, but the packaging becomes difficult to recycle due to mixed materials
Solution Approach 1:
The carrying strap is merged with the cardboard packaging material itself, forming an integral part of the container rather than a separate attached component. This eliminates the need for plastic straps and metal rivets, resolving the material mixing problem while maintaining carrying functionality.
Solution Approach 2:
The carrying strap is made from the same homogeneous cardboard material as the packaging container, eliminating material heterogeneity. This allows the entire packaging to be recycled together as a single material type, solving the recyclability issue.
2Ease of operation
If separate plastic carrying straps with metal rivets are used, then carrying functionality is achieved, but the manufacturing process becomes more complex and costly
Solution Approach 1:
The carrying strap functionality is combined with the packaging structure itself, eliminating separate components. This reduces manufacturing steps by removing the need for separate strap attachment processes involving plastic and metal materials.
Solution Approach 2:
The cardboard material serves multiple functions: it forms the packaging container structure and simultaneously creates the carrying strap. This multi-functionality reduces the number of different components needed and simplifies the manufacturing process.
3Strength
If plastic carrying straps are attached to cardboard packaging, then the packaging can be securely handled, but the separation of materials for recycling becomes difficult
Solution Approach 1:
The carrying strap is made from the same homogeneous cardboard material as the packaging, eliminating the need to separate different materials. The entire packaging can be processed together in recycling facilities designed for cardboard, solving the material separation problem.
Solution Approach 2:
The carrying strap is designed with perforation lines that allow it to be easily separated from the main packaging body along predetermined lines. This segmentation enables simple manual or automated separation if needed, while maintaining the option for integrated recycling.

AI summary
Packaging container (10) made of cardboard, corrugated cardboard, paper or a combination of these materials, comprising a front and a rear wall (12, 16) as well as side walls (14, 18) connecting the front and rear walls (12, 16), and a base structure (24) and a lid structure (22), wherein the lid structure (22) has at least one outer and one inner lid flap (26, 28). At least one connecting flap (40, 42) is hinged to the side of the outer lid flap (26). In addition, at least one carrying strap (44) is formed integrally with the outer lid flap (26) and the lateral connecting straps (40, 42). The carrying strap (44) is defined and limited by means of corresponding perforation and/or cutting lines (46, 48, 50, 52, 54, 56) arranged in the outer lid flap and the connecting flaps (40, 42). Blank (100) for producing a packaging container.
