Cosmetic Inner Container Venting for Hermetic Sealing and Smooth Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic containers face difficulties in hermetic sealing due to air entrapment between the inner cap and intermediate ring, making it hard to close or open the cap, which affects user convenience.
Innovation Solution
A cosmetic cartridge with an exhaust passage formed between the sealing ring and the intermediate ring, allowing air to be exhausted or introduced, facilitating smooth opening and closing of the inner cap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing ring is used to seal the inner cap and intermediate ring, then hermetic sealing performance is improved, but air entrapment occurs making it difficult to open or close the cap
Solution Approach 1:
The sealing structure is segmented into two functional zones: a hermetically attached region for sealing and an exhaust passage region for air evacuation. This segmentation allows the sealing ring to maintain hermetic integrity while providing a dedicated path for air to escape during cap operation.
Solution Approach 2:
An exhaust passage is introduced as an intermediary element between the sealing ring and intermediate ring. This exhaust passage acts as a mediator that allows air to be exhausted from the intermediate ring during cap closing and entering during cap opening, facilitating smooth operation while maintaining sealing integrity.
2Reliability
If the sealing ring is tightly fitted to ensure hermetic sealing, then sealing performance is improved, but air cannot be exhausted causing difficulty in closing the inner cap
Solution Approach 1:
Different regions of the sealing ring have different functional qualities: the hermetically attached region provides tight sealing contact, while the exhaust passage region provides air evacuation capability. This local differentiation of function allows both sealing performance and ease of closing to be achieved simultaneously.
3Reliability
If the sealing ring is tightly fitted to prevent air entry, then hermetic sealing is improved, but air cannot enter the intermediate ring causing difficulty in opening the cap
Solution Approach 1:
The exhaust passage provides a dynamic air exchange mechanism that responds to pressure differential changes during cap opening and closing operations. During closing, it exhausts air; during opening, it allows air entry, making the sealing system dynamically adaptable to operational requirements while maintaining hermetic integrity at rest.
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
Ensures smooth operation of the inner cap by balancing internal and external pressures, maintaining hermetic sealing to prevent cosmetic material contamination while enhancing user experience.
Implementation Method 1
an exhaust passage is formed between the sealing ring and the intermediate ring; when the inner cap is closed onto the intermediate ring, the exhaust passage is configured to exhaust air from the intermediate ring; and when the inner cap is opened, the exhaust passage is configured to allow outside air to enter the intermediate ring
Implementation Method 2
the connecting ring is snap-fitted with the intermediate ring, and the sealing ring can seal the intermediate ring

AI summary
The present disclosure provides a cosmetic cartridge with high sealing performance, and a cosmetic container. The cosmetic cartridge with high sealing performance includes: an inner cap, an intermediate ring, and a powder pan, where the powder pan is fixedly disposed in the intermediate ring; a sealing ring and a connecting ring are fixedly disposed on the inner cap; the inner cap is rotatably connected to the intermediate ring; when the inner cap is closed onto the intermediate ring, the connecting ring is snap-fitted with the intermediate ring, and the sealing ring can seal the intermediate ring; an exhaust passage is formed between the sealing ring and the intermediate ring; when the inner cap is closed onto the intermediate ring, the exhaust passage is configured to exhaust air from the intermediate ring; and when the inner cap is opened, the exhaust passage is configured to allow outside air to enter the intermediate ring. In the container, the exhaust passage is formed between the sealing ring and the intermediate ring, such that air can be exhausted from the intermediate ring through the exhaust passage or can enter the intermediate ring through the exhaust passage, thereby facilitating smooth opening and closing of the inner cap to improve consumer experience.
