Problem
Existing anti-theft devices for bottles and similar containers are not optimal for quick and reliable removal of the latch or locking ring without external assistance.
Innovation Solution
The anti-theft device features a ring with a linear part providing additional elasticity, allowing instantaneous removal from the locking mechanism, combined with a plastic body and specific thicknesses for flexibility and rigidity, along with an electronic theft detection system and a crenelated locking mechanism for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastic means of spring type or elements in elastic material are provided to push the latch out of the body during unlocking, then the device can achieve automatic removal of the latch, but the removal is not quick and reliable enough
Solution Approach 1:
The ring body is segmented into three distinct parts: a circular part for engagement with locking means, a linear part providing elastic recovery, and a curved part connecting them. This segmentation allows each part to perform its specific function optimally, with the linear part dedicated to providing the elastic force needed for quick and reliable removal of the latch.
Solution Approach 2:
The invention changes the physical parameter of the ring body by introducing a linear part with specific thickness (1.2-2.0 mm) that provides controlled elasticity. This parameter change enables the linear part to act as an elastic element that rapidly pushes the latch out of the body when unlocked, achieving both speed and reliability.
2Ease of operation
If the ring body is made completely flexible to enable easy installation, then the device can be easily put in place, but the locking mechanism cannot provide sufficient security
Solution Approach 1:
Different parts of the ring body have different quality characteristics: the circular part has sufficient thickness for rigidity and secure engagement with locking means, the linear part has optimized thickness for flexibility and elastic recovery, and the curved part provides transition. This local differentiation of properties allows the ring to be both easy to install and securely lock.
Solution Approach 2:
The ring body can be made from plastic material with varying local thickness, creating a composite structure where different regions have different mechanical properties. This allows the overall structure to exhibit both flexibility for installation and rigidity for secure locking.
3Strength
If the circular part is made thicker for rigidity and engagement, then the locking engagement is stronger, but the overall flexibility of the ring is reduced
Solution Approach 1:
The ring is segmented into parts with different thicknesses: the circular part is thicker (1.5-2.0 times the linear part thickness) for strong engagement, while the linear part is thinner for flexibility. This segmentation allows each part to have optimized properties for its specific function without compromising the overall performance.

AI summary
An anti-theft device (1) comprising a ring (2), means (4) to lock (4) the ring in the closed position, and anti-theft detection means (3), wherein the ring comprises a body (20) that has a first end (21) near which the locking means are associated, a second opposite free end (22) designed to be introduced in the locking means, and at least one circular part (23) extending from the second end (22) and designed to cooperate with said locking means, characterized in that the body of the ring comprises a linear part (24) that is arranged to extend from the circular part (23) opposite the second end (22). The linear part provides complementary elasticity to the device which contributes to the ejection of the second end of the ring outside the locking means.
