Container Closure Ring Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure devices for containers, particularly those used for drugs, face challenges in securely locking the cap to prevent accidental or fraudulent access, as they may not remain firmly in place on the neck of the container.
Innovation Solution
A closure device featuring a plastic cap with a ring and a maneuvering member that includes a continuous outer peripheral flange and relief, ensuring the locking means are maintained in an active position, preventing removal of the cap without clear indication of the contents being accessed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cap is designed to be removable for access to contents, then ease of operation is improved, but security against fraudulent manipulation deteriorates
Solution Approach 1:
The cap is pre-configured with locking means that automatically engage when the cap is placed on the container neck. The maneuvering member is pre-positioned to activate these locking means, ensuring security is established before any attempt at removal or access, thus preventing fraudulent manipulation while maintaining legitimate access capability
Solution Approach 2:
The cap assembly is divided into functional segments: the cap body, the maneuvering member, and the locking means. This segmentation allows the locking mechanism to operate independently to provide security, while the cap remains removable for legitimate access, resolving the contradiction between ease of operation and security
2Reliability
If the locking means are made more complex to prevent accidental removal, then reliability is improved, but device complexity increases
Solution Approach 1:
The maneuvering member is designed to automatically activate the locking means through its own movement during cap installation. The relief on the maneuvering member self-engages with the locking means without requiring additional actuators or complex control mechanisms, thus improving reliability while minimizing added complexity
Solution Approach 2:
The function of securing the cap and activating the locking mechanism are merged into a single action through the maneuvering member. This integration eliminates the need for separate securing mechanisms, maintaining reliability while reducing overall device complexity

AI summary
The invention relates to a device for stopping a container (1) having a neck (12), said device comprising a stopper (51) and a cap (52) consisting of a plastic material and able to surround both the stopper (51) and the neck (12). The cap (52) comprises a ring (53) that can surround the stopper and the neck when mounted and is provided with means (537) for locking onto the neck, and a body (54) for handling the ring, provided with first means for transmitting a thrust force to the ring and second means (541) for activating means for locking the ring. The ring (53) is provided with a continuous outer peripheral collar (5311), and the handling body (54) is provided with at least one raised element (5431) designed to abut (E4) against the continuous outer peripheral collar (5311) when it activates the locking means (537).
