Cellulose-Based Refill Containers With Barrier Films
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic product packaging is aesthetically sensitive but costly, and plastic containers pose ecological issues with stricter recycling standards, while existing solutions like glass and paper-based containers have limitations.
Innovation Solution
A refillable packaging device with a removable container made of cellulose-based material, covered by a multilayered barrier film, and an outer shell in various materials, ensuring esthetic appeal and ecological sustainability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a plastic removable container is used, then the packaging device can be refilled by replacing the container, but ecological problems arise particularly with recycling
Solution Approach 1:
The patent changes the material parameter of the removable container from plastic to cellulose-based material, transforming it into a recyclable or biodegradable material that reduces ecological impact while maintaining the refillability function
Solution Approach 2:
The patent creates a composite structure by combining cellulose-based material with a barrier film coating, where the barrier film provides the necessary protection against cosmetic product migration while the cellulose base provides recyclability
2Object-affected harmful factors
If a paper-based or card-board-based internal element is used in a glass external element, then the packaging becomes more sustainable, but the cosmetic product may migrate through the porous material
Solution Approach 1:
The patent combines porous cellulose-based material with a non-porous barrier film coating, where the barrier film prevents cosmetic product migration through the porous cellulose material while maintaining the sustainability benefits of the cellulose base
Solution Approach 2:
The barrier film is applied selectively on the inner face of the cellulose-based container that contacts the cosmetic product, providing localized protection exactly where needed to prevent migration while leaving the rest of the cellulose material exposed for sustainability benefits
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
The solution provides an aesthetically pleasing and cost-effective packaging system that minimizes ecological impact by using recyclable materials and prevents cosmetic product migration, while maintaining product integrity.
Implementation Method 1
a barrier film adapted to limit or even prevent the migration of at least one component of the cosmetic product through the cup
