Bottle Closing Device with Tamper-Indicating Security Tab
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current closing devices for bottles of alcoholic drinks do not clearly indicate if the bottle has been opened previously, making it difficult to detect tampering and potential content alteration.
Innovation Solution
A closing device featuring a cap, pourer with a drop-breaker, and a covering liner with an annular breaking line, along with security tabs and elastic teeth that bend and interfere with the pourer's abutment plane upon first opening, visibly indicating the bottle's status by exposing a distinct feature when opened.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional cap and pourer closing device is used, then the bottle can be opened and closed easily, but it does not provide clear indication of whether the bottle has been opened previously
Solution Approach 1:
The patent employs color changes as a visual indicator mechanism. The security tab features a first color on its outer surface that is visible when the bottle is closed, and a second color that becomes visible when the tab is broken or moved, providing clear tamper indication through color transformation.
Solution Approach 2:
The closing device is divided into separable components including the cap, pourer, security tab, and elastic tooth. The security tab can be broken or moved independently from the cap assembly, allowing it to serve as a discrete tamper indication element that segments the indication function from the closing function.
2Reliability
If security tabs with elastic teeth are added to indicate opening, then tamper detection is improved, but the device complexity increases
Solution Approach 1:
The security tab is integrated with the cap assembly through the elastic tooth mechanism, combining the tamper indication function with the existing closing device structure. The elastic tooth engages with the pourer to hold the security tab in place, merging multiple functions into a unified assembly.
Solution Approach 2:
The elastic tooth automatically engages with the pourer to secure the security tab in its initial position, and automatically releases when the cap is opened, providing self-service positioning and indication without requiring additional actuators or complex mechanisms.
3Reliability
If an annular band with breaking line is used, then tampering can be detected, but the indication may not be immediately obvious to the customer
Solution Approach 1:
The security tab uses color changes to provide immediately obvious tamper indication. When the security tab is broken or moved, the outer surface displaying a different color becomes visible, creating a clear and unambiguous visual signal that is easily recognizable by the customer.
Solution Approach 2:
The security tab is positioned to be locally visible on the outer surface of the cap, with its color change specifically oriented to be noticeable in the closed state and when broken. This localized visual feature concentrates the indication information in a prominent location rather than distributing it across the entire bottle.
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 device ensures that opening the bottle is obvious, providing intuitive operation and cost-effective manufacturing while maintaining the bottle's seal, preventing tampering and altering of its content.

AI summary
Closing device (100) for bottles, of the type comprising a cap (1) consisting of a top portion (7) and a side portion (8), a pourer (2), and a covering liner (4), said cap (1) comprising at least one closing tab (9) joined to the top portion (7) of the cap (1), which can take up a first position, of assembly of said closing device (100), in which said closing tab (9) does not interfere with the coupling between said cap (1) and said pourer (2) and a second security position following the first time said device (100) is opened, in which said closing tab (9) interferes with said pourer (2) preventing said device (100) from being completely closed again.
