Container Lid With Broken Line Hinges for Tamper Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional containers with side-part lids fail to maintain a secure seal when deformed, leading to potential spills and lack clear indication of intentional opening, posing risks and difficulties in determining unauthorized access.
Innovation Solution
The container design features a main body with first and second coupling portions, hinge portions, and connecting recesses with broken lines, allowing the lid to be securely closed and easily identifiable as open, using conical cylinder and tapered shapes for secure engagement and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the lid is designed with simple side part engagement, then the device complexity is reduced, but the sealing reliability deteriorates when the container is deformed
Solution Approach 1:
The lid is divided into multiple functional segments: a body portion for covering, a side part for engagement, and multiple hinge portions with broken lines that can be pulled to detach. This segmentation allows the lid to maintain simple overall structure while incorporating reliable sealing mechanisms through the distributed hinge portions that engage with protrusions on the container body.
2Ease of operation
If the engaging point design allows repeated opening and closing, then the ease of operation is improved, but the ability to detect unauthorized opening deteriorates
Solution Approach 1:
The hinge portions are pre-configured with broken lines that remain intact during normal use but are designed to break and separate when pulled. This preliminary setup allows the lid to function normally for repeated openings while creating an irreversible visual change (broken lines separating) that clearly indicates unauthorized opening has occurred.
3Difficulty of detecting and measuring
If the connecting recess periphery comprises a broken line, then the ability to detect opening is improved, but the device complexity increases
Solution Approach 1:
The broken line design creates a visual state change that is easily detectable. When the hinge portions are pulled, the broken lines separate, creating a clear visual indicator that the lid has been opened. This visual detection mechanism is integrated into the functional coupling structure itself, avoiding the need for separate detection devices.

AI summary
A container may include a main body, and a lid is adapted to couple on the main body. The main body has at least two first hinge portions, at least two connecting recesses, and two broken lines respectively formed on the connecting recesses, and the lid comprises at least two cover planes. When the lid is coupled on the main body, the user can pull and detach the first hinge portion from the cover plane to enable the lid to be openable, and the connecting recess is split free from the broken line to make the first hinge portion to be not engaged with the lid again, so that the user can easily identify whether the lid is opened, so as to improve the protection effect of the container.
