Rotatable Cap Projection Seals Cosmetics Dispensing Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetics containers with caps are prone to leakage and contamination due to movement, leading to inefficient dispensing and increased manufacturing complexity.
Innovation Solution
A cosmetics container with a rotatable cap and projection mechanism that opens or closes a dispensing channel through simple rotation, reducing components and complexity while ensuring secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cap is provided at the dispense opening to isolate the dispenser from the outer environment, then leakage prevention is improved, but the structure becomes more complex and manufacturing cost increases
Solution Approach 1:
The cap is merged with the dispenser assembly, forming an integrated unit where the cap serves as both a protective cover and part of the dispensing mechanism. This reduces the number of separate components while maintaining the sealing function, thereby simplifying the overall structure without compromising leakage prevention.
Solution Approach 2:
The cap is designed to serve multiple functions: it isolates the dispenser from the environment to prevent leakage, provides a mounting structure for the dispenser, and enables controlled dispensing through its opening/closing mechanism. This multi-functionality reduces the need for additional components, simplifying the overall structure.
2Ease of operation
If a middle cap and closure part are provided with opening/closing function through rotation, then dispensing control is improved, but the number of components increases and manufacturing becomes more complicated
Solution Approach 1:
The opening/closing function is merged into the cap itself, which rotates relative to the container body to control the dispensing channel. This eliminates the need for separate middle caps and closure parts, reducing the number of components while maintaining effective dispensing control through the rotational movement of the single cap.
3Ease of operation
If the container and dispenser are always in communication, then dispensing convenience is improved, but leakage and contamination occur during movement
Solution Approach 1:
The connection between the container and dispenser is made dynamic through the rotatable cap, which can switch between open and closed positions. This allows the system to adapt between two states: connected for dispensing convenience and disconnected for leakage prevention during movement, resolving the contradiction between constant accessibility and protection against contamination.

AI summary
A cosmetics container, including a container body, a rotatable cap, a dispenser mounted on the rotatable cap, and a cover that covers one end of the container body; the container body is provided with a first through hole, and one end of the container body is formed as a connecting portion; the rotatable cap is provided with a second through hole, and covers the connecting portion to define a sealed cavity; the first through hole, the cavity, and the second through hole define a cosmetics dispensing channel from the container body to the dispenser; a projection which is integrally formed with the connecting portion or the rotatable cap is provided inside the cavity; the projection opens or closes the cosmetics dispensing channel subject to rotation of the rotatable cap.
