Metal Refill Container With Sealing Ring For Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic containers with refill systems are inconvenient to refill, have high component complexity leading to increased assembly costs and reduced cosmetic space due to material limitations, and suffer from leakage issues due to insufficient sealing.
Innovation Solution
A cosmetic container with a refill container holder and a metal refill container featuring a sealing ring with an inverse U-shaped sectional surface and offset sealing protrusion wheels, allowing easy exchange and maximizing cosmetic space while preventing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the refill container is made of synthetic resin, then the manufacturing cost is reduced, but the container thickness must be increased to maintain strength, reducing cosmetic containing space
Solution Approach 1:
The material of the refill container is changed from synthetic resin to metal, fundamentally altering the physical parameters of the container. This material substitution allows for thinner wall thickness while maintaining sufficient strength, thereby maximizing the cosmetic containing space.
2Volume of moving object
If the refill container is made of metal material, then the cosmetic containing space is maximized due to thin thickness, but sealing performance deteriorates causing cosmetic leakage
Solution Approach 1:
A sealing ring is introduced as an intermediary component between the metal refill container and the refill container holder. This sealing ring compensates for the poor sealing properties of metal material, preventing cosmetic leakage while allowing the container to maintain its thin-walled design for maximum capacity.
3Reliability
If a sealing ring is added to the refill container, then sealing performance is improved to prevent leakage, but the number of components increases
Solution Approach 1:
The sealing ring is integrated with the refill container holder to form a unified sealing structure. This integration reduces the number of separate components while maintaining the sealing function, as the sealing ring becomes part of the holder assembly rather than a completely separate part.

AI summary
The present invention relates to a cosmetic container comprising a refill container having a sealing ring and, more specifically, to a cosmetic container comprising a refill container having a sealing ring, the cosmetic container having a refill container holder embedded in an outer case, and having the refill container, which contains cosmetics, used by being coupled to the refill container holder, and improving refill convenience since after the cosmetics are completely used, a user easily separates the refill container from the refill container holder by pressing the refill container on the top thereof, and then can couple a new refill container to the refill container holder from the bottom of the outer case, thereby easily replacing the refill container.
