Lip Gloss Container Segmented Storage and Wiper Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lip gloss containers contaminate cosmetic contents in the container when the application tip is used, as the space for used and unused cosmetics is not separated, leading to contamination.
Innovation Solution
A lip gloss container design featuring a cylindrical cap, a lower container, a cylindrical tube, a shoulder member, a brush rod receiving member, and a valve system that separates the cosmetic contents in the container from those on the application tip, preventing mixing and contamination through a check valve and piston mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the application tip is used to apply cosmetics, then the cosmetic application function is achieved, but the cosmetic contents in the container become contaminated by the used cosmetics on the application tip
Solution Approach 1:
The container is divided into a first container for storing unused cosmetic contents and a second container for storing used cosmetic contents. The application tip moves between these two containers, allowing separation of clean and used cosmetics to prevent contamination while maintaining application functionality.
Solution Approach 2:
A wiper member is introduced as an intermediary component that contacts the application tip to remove excess cosmetics before the tip is inserted into the first container. This mediator prevents direct contamination between used and unused cosmetic contents.
2Ease of manufacture
If the application tip is inserted into the container to store unused cosmetics, then storage is achieved, but used cosmetics contaminate the unused cosmetics in the container
Solution Approach 1:
The container is segmented into two separate storage spaces: a first container for unused cosmetics and a second container for used cosmetics. This segmentation allows the application tip to be stored in the first container without contaminating the unused cosmetics, while maintaining a designated area for used cosmetics.
Solution Approach 2:
The wiper member performs preliminary action by removing excess cosmetics from the application tip before it is inserted into the first container. This preliminary cleaning action prevents potential contamination of the unused cosmetics stored in the first container.

AI summary
A lip gloss container, having: a cap of a cylindrical member, to a lower center of which a brush rod is fitted and at a lower inner circumference thereof a female screw is formed; a lower container of a cylindrical member, the upper portion of which is open and the bottom portion thereof is closed to contain cosmetic contents; a cylindrical tube having opened top and bottom portions, which is inserted through the upper opening of the lower container; and a shoulder member provided with a male screw which is coupled to the upper outer circumference of the cylindrical tube so as to be coupled with a female screw of the cap at the upper outer circumference. The container has such an effect that cosmetic contents introduced into a brush rod receiving member and cosmetic contents in the lower container are not mixed with each other so that cosmetics in the container are not contaminated by cosmetics in use.
