Cosmetic Container with Retractable Brush and Sealing Stopper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nail polish containers are inconvenient due to frequent immersion and removal of the brush, risk of accidental bottle falls, and volatility issues leading to product hardening and spoilage.
Innovation Solution
A cosmetic container design featuring a rod insertion container with liquid inflow holes, a brush support mechanism with an extendable part and elastic member, and a cap with a sealing stopper to stabilize the liquid and prevent leakage, allowing for easy brush access and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional nail polish container with a brush attached to a support rod is used, then the brush can be easily accessed, but the user must frequently immerse and remove the brush, causing inconvenience
Solution Approach 1:
The brush support piece is designed to be movable rather than fixed. When the user presses the pressing member, the brush support piece moves in the first direction to extend the brush outward. When pressure is released, the elastic member restores the brush support piece to its initial position, automatically retracting the brush. This dynamic mechanism eliminates the need for manual immersion and removal operations.
Solution Approach 2:
The elastic member automatically restores the brush support piece to its initial position without requiring user intervention. The system serves itself by using the elastic restoration force to retract the brush after use, eliminating the need for the user to manually retract the brush or re-immerse it in the nail polish.
2Ease of operation
If the container is opened for brush access, then the brush can be used, but the nail polish is exposed to air and may volatilize or harden
Solution Approach 1:
The brush support piece dynamically extends and retracts based on user needs. When the brush is not in use, it automatically retracts into the container, maintaining the sealed environment and preventing nail polish exposure to air. This dynamic positioning ensures the product remains stable while still allowing easy brush access when needed.
Solution Approach 2:
The brush support piece acts as an intermediary mechanism between the brush and the nail polish. It allows the brush to extend into the nail polish only when needed, while maintaining the sealed container environment otherwise. This intermediary structure enables controlled access without compromising product stability.
3Device complexity
If a simple coupling method is used for the stopper, then the structure is simple, but the stopper cannot completely cover the opening and nail polish volatilizes
Solution Approach 1:
The pressing member is designed to be movable rather than fixed. When pressed, it pushes the brush support piece to extend the brush. When released, it allows the elastic member to restore the brush support piece. This dynamic mechanism provides reliable sealing when the brush is not in use while still enabling easy brush access when needed, resolving the contradiction between sealing force and operational convenience.
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
The design enhances user convenience by reducing the need for repeated brush immersion, prevents accidental spills and hardening of nail polish, and extends the product's lifespan by maintaining a stable sealing structure.
Implementation Method 1
an elastic member accommodated in the rod insertion container, and laid on at least a part of an outer peripheral surface of the brush support piece to restore the brush support piece, which has moved in a first direction outside the main body, in a second direction opposite to the first direction

AI summary
Disclosed is a cosmetic container. The cosmetic container includes: a main body, in which a liquid material is stored; a rod insertion container inserted into the main body and provided with one or more liquid inflow holes, through which the liquid material stored in the main body flows in; a forcibly inserting means for drawing out a brush to the outside; a brush supporting means including a brush support piece mounted with a brush; an elastic member, and a cap. According to the present invention, it is possible to prevent a cosmetic liquid from being hardened inside a container by securing a sealing structure of the cosmetic container. Further, according to the present invention, it is possible to stably keep a cosmetic container, thereby extending a lifespan of a product. Further, according to the present invention, it is possible to enable a user to more conveniently and easily wear nail polish compared to an existing method in using a cosmetic container.
