Cosmetic Container Inner Wall Scraper Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers face issues with residual cosmetics remaining on the inner walls, leading to waste and potential mixing with undesirable substances, as well as cosmetic deterioration due to air contact and improper usage.
Innovation Solution
A cosmetic container with a pipe-shaped scraper featuring a concave slope and helical ridge to scrape and move residual cosmetics downward, combined with a retainer and sealing ring for improved sealing and ease of rotation, allowing for complete usage and preservation of cosmetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the container main body is formed into a cylindrical shape for convenient use and carrying, then the container is small in size and portable, but the viscous cosmetics remain on the inner wall and cannot be completely used
Solution Approach 1:
The invention extracts the scraper from the cap structure and places it directly in the container main body, allowing the scraper to independently contact and remove cosmetics from the inner wall without relying on the cap's position or movement
Solution Approach 2:
The scraper acts as an intermediary tool between the user and the cosmetics, providing a mechanical means to actively remove residual cosmetics from the inner wall, thereby enabling complete usage of the cosmetic product
2Reliability
If the container is sealed to prevent air contact, then cosmetic deterioration is prevented, but residual cosmetics solidify due to air contact over time when recharging
Solution Approach 1:
The scraper is pre-positioned in the container main body at the lowest point, ready to immediately scrape and remove residual cosmetics before they can solidify due to air contact, preventing the harmful effect before it occurs
Solution Approach 2:
The scraper enables the cosmetics system to self-clean by automatically removing its own residuals from the inner wall, preventing solidification and maintaining the cosmetic's usable state without external intervention
3Device complexity
If the scraper is provided without rotary motion capability, then the structure is simple, but the scraper cannot effectively scrape and move residual cosmetics downward
Solution Approach 1:
The scraper is designed with rotary motion capability around the rotation rod, transforming it from a static component to a dynamic one that can actively scrape the inner wall by rotating, thereby significantly improving cosmetic removal effectiveness
Solution Approach 2:
The scraper is formed with a curved inner circumferential surface that matches the cylindrical shape of the container main body, allowing it to conform to and effectively scrape the inner wall surface during rotation
4Device complexity
If the scraper is provided without sealing components, then the structure is simple, but cosmetics can leak through the bottom hole when the container is tilted
Solution Approach 1:
A flexible sealing ring is provided that can deform and conform to the container's inner wall and bottom hole, creating an effective seal that prevents cosmetic leakage while allowing the scraper to rotate freely
Solution Approach 2:
The sealing ring is designed to be flexible and dynamic, able to adjust its position and shape to maintain sealing effectiveness during the scraper's rotation and when the container is tilted at various angles

AI summary
A cosmetic container allows all of the residual cosmetics remaining on the inner wall of the cosmetic container to be used by having the scraper within the container main body that receives the cosmetics.
