Bottle Closure Cap With Tear-Off Band for Visible Tamper Evidence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ROPP closure caps are vulnerable to tampering, counterfeiting, and lack a clear indication of opening, making them unsuitable for applications requiring high tamper-proof protection and returnable bottle policies.
Innovation Solution
A closure cap with a breakable annular band and tear-off tab, made of aluminium alloy, featuring a tamper-evident design and a flexible tab for easy opening, ensuring visible tampering evidence and secure sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional ROPP closure cap with tamper-proof annular band is used, then air tightness and basic tamper-proof capability are ensured, but the cap remains vulnerable to tampering by expert people and lacks clear visible indication of tampering
Solution Approach 1:
The patent applies a color-coded ring or band on the closure cap that changes color or shows visible indication when the cap is tampered with or opened. This visual change provides clear evidence of tampering to consumers, resolving the issue of invisible tampering evidence in conventional ROPP caps.
Solution Approach 2:
The closure cap is divided into functional segments including a breakable seal ring, a tamper-evident band, and a reusable cap body. The breakable seal ring segment provides visible fragmentation evidence when broken, making tampering detectable while maintaining the overall cap structure.
2Reliability
If the tamper-proof annular band is made integral with the bottle after opening, then tamper evidence is provided, but the empty bottle cannot be returned and requires expensive mechanical separation
Solution Approach 1:
The closure cap system is segmented into a permanent tamper-evident seal ring that breaks and remains on the bottle, and a removable cap body that can be taken off and returned with the empty bottle. This segmentation allows tamper evidence to be maintained while enabling bottle returnability.
Solution Approach 2:
The tamper-evident function is extracted into a separate breakable seal ring component that stays with the bottle, while the main cap body is made removable and returnable. This extraction resolves the conflict between providing tamper evidence and enabling bottle return.
3Reliability
If the closure cap is designed to resist forced burglary attempts, then security is improved, but the cap becomes more fragile and vulnerable to breakage
Solution Approach 1:
The closure cap uses a segmented design where the main cap body maintains structural integrity for reuse, while separate security features like breakable seal rings provide burglar resistance through controlled fragmentation rather than overall structural weakening.
4Ease of operation
If conventional ROPP closure caps are used, then ease of opening is maintained, but the caps are vulnerable to counterfeiting due to lack of unique safety features
Solution Approach 1:
The closure cap incorporates color-coded rings or bands with unique color combinations or patterns that serve as authentication features. These visual elements maintain ease of opening while providing counterfeiting resistance through unique identifiable characteristics.

AI summary
A closure cap (10) consisting of a hollow cylindrical body is described, which comprises a capsule-shaped cap portion (12) and an open or C-shaped annular band (20), which is made integral in a breakable way with the cap portion (12) by means of a breakable circumferential edge (22) having a low thickness. At least one threaded portion (28), which is obtained during the process of applying the closure cap (10) to a threaded mouth of a bottle is provided on the side surface (14). At least one flexible tab (26) is attached to the annular band (20) in such a way that a user of the closure cap (10) can obtain, by pulling the tab (26), the removal of the annular band (20) by breaking the breakable circumferential edge (22). The irreversible separation of the cap portion (12) and the open or C-shaped annular band (20) is thereby obtained, making the closure cap (10) first opening visible.
