Tamper-Evident Container With Segmented Locking System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers with locking systems for forgery-proof storage lose their security function after initial use, as the security ring's separating area is destroyed upon first closure, and they are costly to produce.
Innovation Solution
A container design featuring a cup-shaped body, closure cap, ratchet ring, locking ring, and sealing ring, where the ratchet ring is positively connected to the closure cap using injection molding or welding, with pawls engaging locking cams to prevent unscrewing and a detachable securing ring that can be opened by destroying a predetermined separation area, ensuring reliable non-destructive opening and secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a security ring with a separating area is used to prevent unauthorized opening, then forgery-proof storage is achieved, but the security function is lost after the first opening
Solution Approach 1:
The locking system is divided into two independent groups: a first group of locking means that engages with the closure cap and a second group that engages with the container body. This segmentation allows the first group to be destroyed during initial opening while the second group maintains ongoing security protection.
Solution Approach 2:
The patent provides preliminary action by having the closure cap perform a preliminary opening operation that destroys the separating area of the security ring, enabling first opening while preventing subsequent unauthorized openings through the remaining locking mechanism.
2Reliability
If a locking system with a security ring is implemented, then unauthorized opening is prevented, but production costs increase
Solution Approach 1:
The locking means are integrated directly into the closure cap structure, merging the locking function with the closure mechanism. This integration reduces the number of separate components and simplifies the manufacturing process while maintaining security functionality.
Solution Approach 2:
The closure cap serves multiple functions: it closes the container opening, provides the locking mechanism through integrated locking means, and enables controlled opening through the separating area. This multi-functionality reduces the need for additional separate security components.
3Device complexity
If the closure cap is designed with integrated locking means, then device complexity is reduced, but the locking mechanism becomes more vulnerable to failure
Solution Approach 1:
The locking means are positioned at specific critical locations on the closure cap where they engage with corresponding elements on the container body. This localized positioning ensures reliable engagement at key points while maintaining overall system simplicity.
Solution Approach 2:
The patent incorporates a separating area in the security ring that is designed to be destroyed during the first opening operation. This beforehand cushioning allows the locking mechanism to accommodate the first opening while maintaining security for subsequent operations.
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 container ensures reliable non-destructive opening for initial filling and secure closure, preventing unauthorized access, while allowing destruction of the closure cap for emptying, thus maintaining security and reducing production costs.
Implementation Method 1
When the closure cap (3) is screwed onto the container body (2) for the first time, these pawls (10) slide resiliently over locking cams (11)
Implementation Method 2
after the closure cap has been completely unscrewed, comes into sealing contact with a slightly conical inner surface of the closure cap

AI summary
The container has a closing cap (3), which is screwed with a container body (2). The closing cap is connected with the container body in a non-detachable and nondestructive manner before the initial use and after its filling in the closed position. Two groups of locking units are provided at the container, which are designed for engagement with the locking units of the closing cap.
