Cosmetic Container Air Circulation Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers face issues with air compression leading to reduced sealing strength and compromised airtightness, which causes evaporation of volatile solvents and moisture, and complex structures increase production costs and decrease opening/closing sensitivity.
Innovation Solution
A cosmetic container with an air circulation surface featuring a first and second sealing protrusion, where the air circulation surface includes fine protrusions and grooves, allowing uniform air distribution and introduction, enhancing sealing strength and opening/closing sensitivity by preventing the lid from being lifted during closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inner container lid is closed to seal the inner container, then the sealing strength is improved, but the air in the inner container is compressed causing the lid to be lifted and sealing strength to deteriorate
Solution Approach 1:
The sealing protrusion surface is segmented into multiple fine protrusions and grooves, creating multiple small contact points instead of a single large contact surface. This segmentation allows air to be distributed and released through multiple pathways, preventing the lifting effect while maintaining sealing contact.
Solution Approach 2:
The sealing protrusion is given a non-uniform surface structure with fine protrusions and grooves, creating areas of different local properties. The grooves act as air release channels while the protrusions maintain sealing contact, allowing different regions to serve different functions simultaneously.
2Reliability
If a valve body with tension plate and protrusion film is installed to discharge compressed air, then the lifting problem is solved, but the structure becomes complicated and productivity is lowered
Solution Approach 1:
The air release function is merged directly into the sealing protrusion structure itself, eliminating the need for separate valve bodies, tension plates, and protrusion films. The sealing protrusion on the lid integrates both sealing and air release functions, simplifying the overall structure and reducing assembly steps.
Solution Approach 2:
The air release function is extracted from a separate complex valve mechanism and integrated into the simple surface texture of the sealing protrusion. This extraction eliminates unnecessary components while maintaining the air release capability through the fine groove structure.
3Ease of operation
If the sealing protrusion surface is made smooth for easy contact, then the opening/closing operation is smooth, but air compression causes lifting and reduced sealing
Solution Approach 1:
The sealing protrusion surface is given a non-uniform texture with fine protrusions and grooves, creating areas of different local properties. The grooves act as air release channels while the protrusions maintain sealing contact, allowing different regions to serve different functions simultaneously.
Solution Approach 2:
The sealing protrusion surface is segmented into multiple fine protrusions and grooves, creating multiple small contact points instead of a single large contact surface. This segmentation allows air to be distributed and released through multiple pathways, preventing the lifting effect while maintaining sealing contact.

AI summary
Disclosed is a cosmetic container having an air circulation surface, which includes an inner container for containing a content therein and an inner container lid provided with a sealing protrusion wheel for sealing the inner container. The cosmetic container includes a first sealing protrusion formed on the inner container; a second sealing protrusion formed on the sealing protrusion wheel of the inner container lid; and the air circulation surface including a fine protrusion and a groove provided on the first sealing protrusion of the inner container or the second sealing protrusion of the inner container lid, wherein air compressed in the inner container is discharged while being uniformly distributed over the entire air circulation surface when the inner container lid is closed, and outside air is introduced into the inner container through the entire air circulation surface when the inner container lid is opened.
