Recyclable Container Blank with Integrated Web Retainer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging methods for non-flat articles, such as bottles and machine parts, often result in damage during transit due to movement within containers, and current solutions either require excessive packaging materials or additional processing steps, increasing costs and waste.
Innovation Solution
A container blank made of card or cardboard with a web of material secured to the side walls and lid, extending beyond the open mouth, uses cohesive portions with adhesive to secure articles within the container, minimizing movement and waste while being fully recyclable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple container blank is used for packaging non-flat articles, then manufacturing cost is reduced, but articles move and damage occurs during transit
Solution Approach 1:
The patent merges the container structure with an integrated article retaining means formed from the same card or cardboard material. The retaining means includes features such as a retaining wall and base portion that are formed as one piece with the container blank, eliminating the need for separate packaging materials and reducing manufacturing complexity while preventing article movement.
Solution Approach 2:
The patent utilizes the flexible nature of card and cardboard to form a retaining means that can conform to the shape of the article while providing structural support. The flexible material allows the container to be formed into a three-dimensional shape with integrated retaining features that secure the article without requiring rigid additional components.
2Reliability
If additional packaging materials are used to secure articles, then article protection is improved, but packaging waste increases
Solution Approach 1:
The patent combines the container and article retaining means into a single integrated structure formed from one piece of card or cardboard. This eliminates the need for separate packaging materials such as additional boxes, wrapping paper, or cushioning materials, thereby reducing packaging waste while maintaining article protection.
Solution Approach 2:
The container blank is designed to serve multiple functions: it provides the outer container structure and simultaneously forms the article retaining means. The integrated design allows the same material to perform both containment and article securing functions, eliminating the need for additional specialized packaging materials.
3Device complexity
If traditional container designs are used for non-flat articles, then container simplicity is maintained, but additional processing steps are required to prevent movement
Solution Approach 1:
The article retaining means is formed as an integral part of the container blank during the initial forming process, before the article is placed inside. This preliminary formation of the retaining structure eliminates the need for subsequent additional processing steps such as assembling separate retention components or applying additional fastening operations.
Solution Approach 2:
The patent merges the container forming process with the article retaining means formation into a single operation. The retaining means is formed as one piece with the container using the same blank material, eliminating the need for multiple separate processing steps and reducing overall packaging process complexity.
