Packaging System Sealed Closure Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic product packaging systems fail to maintain a good seal, leading to air or polluting agents entering the receptacle and altering the product's physico-chemical properties, and often have complex designs that risk accidental detachment or difficult handling.
Innovation Solution
A packaging system with a protective device that includes a cap and releasing mechanism, utilizing snap-fitting means and return means to maintain a sealed contact between the closing member and the receptacle, ensuring easy handling and reducing the risk of spontaneous release, while allowing for easy separation and reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the closing member is designed to be easily removable for product application, then the ease of operation is improved, but the reliability of the seal deteriorates due to risk of accidental detachment
Solution Approach 1:
The patent implements a dynamic locking mechanism where the closing member transitions between a locked position (during transport and storage) and an unlocked position (during application). The release mechanism allows intentional dynamic transition while preventing accidental transitions, resolving the contradiction between ease of removal and seal integrity.
Solution Approach 2:
The patent introduces an intermediary release mechanism that mediates between the closing member and the receptacle. This intermediary component requires deliberate action to activate, providing a controlled transition state that prevents accidental detachment while maintaining easy intentional removal.
2Reliability
If a protective device with holding means is added to prevent accidental detachment, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The patent merges the protective device, holding means, and release mechanism into an integrated assembly that works with the closing member. By combining multiple functions into unified components, the patent reduces overall part count while maintaining reliability improvements.
Solution Approach 2:
The protective device is designed with multi-functionality, serving both as a protective cover and as part of the locking/release mechanism. This universal design allows a single component to perform multiple functions, reducing the total number of parts needed while improving reliability.
3Reliability
If the closing member is tightly sealed to the receptacle, then the reliability of seal is improved, but the ease of operation deteriorates due to difficulty in separation
Solution Approach 1:
The patent implements a dynamic sealing mechanism where the seal strength varies based on the operational state. During transport, the seal is tight and locked; during application, the release mechanism dynamically reduces seal strength to allow easy separation. This dynamic adjustment resolves the contradiction between seal integrity and ease of separation.
Solution Approach 2:
The patent applies preliminary anti-action by pre-setting the closing member in a locked position with strong sealing during transport. The release mechanism is pre-configured to counteract this locking force when activated, allowing easy separation when needed while maintaining strong seal during storage.
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 system effectively maintains a good seal against solvents and ambient air, is easy to manufacture and handle, and reduces the risk of accidental detachment, ensuring the product's integrity and ease of use.
Implementation Method 1
return means capable of applying an axial force to the packaging and application system in order to maintain a sealed contact or pressure between the closing member and the storage receptacle

AI summary
The assembly comprises a system for the packaging and application of a product and a device for protecting said system. The system comprises a receptacle for storing the product, a product applicator, and a member for closing the receptacle bearing the applicator. The protective device comprises a cap mounted on the system and at least one means for releasing the system. The releasing means comprises a means for holding the system relative to the device and a means for actuating the holding means in order to render the holding means inactive and at least partly separate the system and the protective device. The assembly also comprises return means capable of maintaining a sealed contact between the closing member and the storage receptacle in an active position of the holding means.
