Fliptop Blister Container Closure for Reusable Leak-Resistant Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blister packaging containers cannot effectively seal after the discharge hole is opened, leading to potential leakage due to the release of the locking mechanism and formation of an empty space.
Innovation Solution
A blister packaging container with a shoulder part-integrated fliptop cap that includes a locking portion and a guide portion to securely close the discharge hole, utilizing a cap cover with an opening and closing protrusion to ensure multiple openings and closings without creating an empty space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional blister packaging container with a discharge hole and cover film is used, then the container can be opened for access, but the discharge hole cannot be closed again after opening, leading to potential leakage
Solution Approach 1:
The cap is designed to be movable between open and closed positions, allowing the discharge hole to be dynamically opened and closed multiple times. The cap rotates about a hinge axis, enabling it to move between a first position (open) and a second position (closed), transforming a static seal into a dynamic reusable seal.
Solution Approach 2:
The cap structure is divided into separate functional components: a cap body with discharge hole, a cap cover that seals the hole, and a hinge mechanism. This segmentation allows independent optimization of each component's function while enabling repeated opening and closing operations.
2Reliability
If a folding sealing piece with locking pieces is used to close the discharge hole, then the hole can be sealed, but external force causes the locking pieces to escape, creating empty space and permitting leakage
Solution Approach 1:
The cap cover and discharge hole are integrated into a single rigid cap structure, eliminating the separate folding sealing piece and locking pieces. The seal is formed by the cap cover directly engaging with the discharge hole opening, creating a unified structure that cannot escape or deform under external force.
Solution Approach 2:
The conventional folding sealing piece with locking pieces acts as a disposable or single-use component that fails under external force. The invention replaces this with a durable, reusable cap structure designed to withstand repeated use and external forces without degradation of sealing performance.
3Ease of operation
If the cap cover is foldably connected to the cap body, then the cap can be opened and closed, but the connection structure increases device complexity
Solution Approach 1:
The hinge connection is designed to be self-contained within the cap structure, requiring no external components or complex assembly. The hinge axis is integrated into the cap body, and the cap cover rotates about this axis, allowing the cap to serve its own opening and closing function without additional mechanisms.
