Cosmetic Refill Container With Bell Profiles and Segmented Jacket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cosmetic paste containers face challenges in reducing non-recyclable material usage and high production costs while maintaining a safe, lightweight, and functional structure, with existing soft containers being fragile and prone to leakage issues.
Innovation Solution
A container design featuring a reusable rigid outer jacket with a flexible cartridge that minimizes plastic waste, allowing for easy replacement and ensuring product quality, comprising a pair of bell profiles forming a central reservoir for the cartridge and engagement areas with the jacket, along with a detachable applicator rod for secure and leak-proof makeup application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid container is used for cosmetic paste, then product preservation and leakage prevention are improved, but manufacturing cost and environmental impact increase
Solution Approach 1:
The container is divided into two separate parts: a rigid outer container that provides structural support and protection, and a soft inner container that directly holds the cosmetic paste. This segmentation allows each component to fulfill its specific function optimally while reducing overall material usage and cost.
Solution Approach 2:
The soft inner container is nested within the rigid outer container, creating a hierarchical structure where the softer, more cost-effective inner container is protected by the rigid outer shell during storage and transport, but can be easily removed for refilling.
2Ease of manufacture
If a soft container is used for cosmetic paste, then manufacturing cost and environmental impact are reduced, but structural strength and leakage prevention worsen
Solution Approach 1:
The container system separates the structural support function (handled by the rigid outer container) from the product containment function (handled by the soft inner container), allowing the soft container to be lightweight and cost-effective while still providing adequate protection through the outer rigid shell.
Solution Approach 2:
The container system uses a composite structure combining rigid and soft materials, where the rigid outer container provides mechanical strength and the soft inner container provides flexibility and product compatibility, creating a synergistic system that overcomes the limitations of either material alone.
3Weight of moving object
If a soft container is used for cosmetic paste, then weight is reduced, but reliability and leakage prevention worsen
Solution Approach 1:
The container is segmented into a rigid outer shell that prevents deformation and leakage during transport, and a lightweight soft inner container that reduces overall weight while maintaining product containment through the protective outer structure.
Solution Approach 2:
The lightweight soft container is nested within the protective rigid outer container, allowing the inner container to be lightweight for reduced shipping weight while the outer container provides the structural integrity needed to prevent leakage and damage during handling and transport.
4Ease of operation
If a rigid container is used for cosmetic paste, then ease of use is improved, but environmental impact and manufacturing cost increase
Solution Approach 1:
The container system is segmented to allow the rigid outer container to be reused multiple times for its durability and ease of handling, while the soft inner container can be replaced with refills, reducing the need to manufacture entirely new rigid containers and thereby reducing environmental impact.
Solution Approach 2:
The design enables recovery and reuse of the rigid outer container while the soft inner container or its contents can be discarded and replaced, allowing the environmentally friendly soft container material to be used in smaller quantities repeatedly within the durable outer shell.

AI summary
Container for cosmetics generally comprising a vessel and a closing element, wherein the vessel has a profile comprising a jacket having a profile comprising a pair of opposite bell profiles. The tails of each bell profile are in contact with the tails of the other bell profile, and the opposite bells of the two bell profiles respectively form a central reservoir area wherein is housed a flexible cartridge containing the cosmetic material, and two opposite housing and engagement areas for the side walls of the cartridge.
