Cosmetic Compact Refill Case with Elastic Mesh Screen
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetics compacts with refill cases have limited storage capacity for liquid cosmetic substances, leading to leakage and vaporization issues when the refill case is opened.
Innovation Solution
A compact design featuring a rotatable upper and lower case with a detachable refill case, incorporating a high elasticity mesh screen cover with a border rim part and vertically extending ring to securely hold and prevent leakage of cosmetic contents, along with a sponge cover for additional protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a porous pad is used to hold liquid cosmetic substance in the refill case, then the liquid cosmetic substance can be held and applied, but the storage capacity is limited and the liquid may flow out or vaporize when exposed
Solution Approach 1:
The patent employs a flexible mesh screen made of elastic material that can be stretched and deformed. The mesh screen acts as a flexible barrier to hold the liquid cosmetic substance while allowing it to be dispensed. When the refill case is opened, the mesh screen prevents direct exposure of the liquid, reducing vaporization and leakage while maintaining accessibility for application.
2Ease of operation
If the refill case is opened to use the cosmetic substance, then the substance can be accessed, but direct exposure causes vaporization and potential leakage
Solution Approach 1:
The mesh screen serves as an intermediary between the liquid cosmetic substance and the external environment. It allows users to access and apply the cosmetic substance while simultaneously preventing direct exposure that would cause vaporization and leakage. The intermediary structure enables controlled interaction between the user and the cosmetic substance.
3Reliability
If the mesh screen cover is tightly received in the case mainbody, then the cosmetic contents are protected from exposure, but the structure becomes more complex
Solution Approach 1:
The mesh screen cover is nested within the refill case structure, with the border rim part received in a corresponding groove in the case mainbody. This nested arrangement allows the mesh screen to be tightly secured without requiring additional external components or complex assembly mechanisms, achieving protection while maintaining structural simplicity.
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
Enhances storage capacity and reduces vaporization by preventing direct exposure of cosmetic contents to the outside environment, allowing for efficient use and maintaining product integrity.
Implementation Method 1
a high elasticity mesh screen which has a border area supported by the border rim part to extend inwardly so as to cover the contents for cosmetics from an outside
Implementation Method 2
a vertically extending ring part which extends vertically from a lower side of the lower ring part to be tightly contact an inner wall of the case mainbody

AI summary
The present invention relates to a compact for cosmetics comprising an upper case, a lower case rotatably coupled to the upper case and a refill case detachably received in the lower case, wherein the refill case comprises a case mainbody where contents for cosmetics are received; a case cover which opens and closes the case mainbody; and a mesh screen cover having a border rim part which is received in the case mainbody to be tightly received within a wall of the mainbody, and a high elasticity mesh screen which has a border area supported by the border rim part to extend inwardly so as to cover the contents for cosmetics from an outside. Accordingly, expanded space is provided for receiving contents for cosmetics, the contents for cosmetics is prevented from flowing out of the refill case by the high elasticity mesh screen covering the contents for cosmetics, and the contents for cosmetics is prevented from being directly exposed to the outside thus decreasing vaporization when the case is open.
