Cuboid Detergent Packaging Stability and Material Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detergent packaging solutions face challenges in achieving transport and storage stability while minimizing the use of non-biodegradable materials and reducing packaging volume, as they often rely on water-insoluble polymer films that are not environmentally friendly.
Innovation Solution
A detergent supply form featuring a cuboid outer packaging with a medium filling level, designed as a one-piece folding box with hollow side walls and a resealable lid, using recycled or biodegradable materials, which stabilizes detergent tablets through careful arrangement and reduced packaging material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If detergent tablets are packaged using individual flow pack packaging with water-insoluble polymer films, then physical integrity and chemical stability are improved, but environmental sustainability deteriorates and packaging volume increases
Solution Approach 1:
The patent changes the material parameter from water-insoluble polymer films to water-soluble packaging materials. This allows the packaging to maintain its protective function during transport and storage while enabling biodegradation and recycling, thus resolving the contradiction between stability and environmental sustainability.
Solution Approach 2:
The patent employs a disposable outer packaging that is designed to be biodegradable and recyclable. This replaces the traditional permanent flow pack structure with a temporary protective barrier that decomposes after use, eliminating the need for complex recycling systems while maintaining environmental friendliness.
2Strength
If detergent tablets are packaged using individual flow pack packaging, then physical integrity is improved, but packaging volume per dosing unit increases
Solution Approach 1:
The patent merges multiple detergent tablets into a single outer packaging unit, replacing individual flow packs with a collective container. This consolidation reduces the total packaging volume while maintaining physical integrity through a unified protective structure that safeguards all tablets simultaneously.
3Loss of substance
If detergent tablets are arranged in layers with high fill level, then packaging material usage is reduced, but transport and storage stability deteriorates
Solution Approach 1:
The patent segments the outer packaging into multiple compartments or layers that separately accommodate individual detergent tablets. This segmentation prevents direct contact between tablets, reduces clumping, and maintains physical stability during transport while using minimal packaging material through efficient space utilization.

AI summary
A detergent packaging form comprising: a) an outer packaging with a base, a lid, and side walls connecting the base and lid; b) cuboid detergent bodies with a bottom, a top, and a lateral surface connecting the bottom and top; wherein: i) the outer packaging contains at least eight detergent bodies arranged in layers within the outer packaging such that each detergent body is adjacent to at least three other detergent bodies; ii) the outer packaging has a fill level of 50% to 84% by volume; iii) 35% to 80% of the empty volume of the outer packaging is located between the top of the upper layer of detergent bodies and the inside of the lid.
