Bottle Closing Device with Irreversible Lever and Color Change Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle closing devices for alcoholic drinks do not clearly indicate when the bottle has been opened for the first time, making it difficult to detect subsequent openings and potentially allowing alteration or contamination.
Innovation Solution
A closing device with a lever element that irreversibly moves from a first to a second position upon initial opening, preventing complete closure and visibly indicating the bottle's status through a contrasting color on the coating after the first opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a traditional cap and pourer closing device is used, then the device is simple to manufacture and operate, but it cannot clearly indicate when the bottle has been opened for the first time or subsequent times
Solution Approach 1:
The coating includes a first portion and a second portion with contrasting colors. When the predetermined breaking line is lacerated during first opening, the coating divides into top and bottom portions, revealing the contrasting color configuration that clearly indicates the bottle has been opened. This visual color change provides permanent, obvious indication of opening status without requiring complex electronic or mechanical systems.
2Reliability
If no intermediate indication mechanism is provided, then the device structure remains simple, but it cannot prevent or indicate subsequent unauthorized openings after the first opening
Solution Approach 1:
The coating is segmented into a first portion and a second portion with contrasting colors, and further divided into top and bottom portions when the breaking line is lacerated. The cap is segmented into a tubular side portion and a central portion, with the central portion movable between first and second positions. This segmentation allows the device to provide clear visual indication of opening status through the relative positions and colors of the segmented components.
Solution Approach 2:
The lever element acts as an intermediary mechanism between the cap and the closing action. When the central portion moves to the second position after first opening, the lever element prevents the cap from fully closing, providing an intermediate state that clearly indicates the bottle has been opened. This intermediary mechanism translates the opening event into a permanent, visible state change.
3Object-affected harmful factors
If the cap can be completely closed after opening, then the device maintains simplicity of operation, but it allows alteration or contamination of bottle content without clear indication
Solution Approach 1:
The device applies preliminary anti-action by positioning the lever element and central portion to prevent complete closure after the first opening. The contrasting color configuration is established before opening, and the breaking of the predetermined breaking line triggers the anti-closure action, preventing any subsequent closing that would hide the opening status. This preliminary setup ensures that once opened, the bottle cannot be closed without maintaining the open indication.

AI summary
Device (100) for closing bottles of alcoholic drinks and spirits of the type comprising a cap (1), a pourer (2), suitable for being fixed to the neck of the bottle (3), and a coating (4). The cap (1) comprises at least one lever element (5) irreversibly mobile between a first position, achieved prior to assembly of the closing device (100), and a second position in which, once installed on the bottle and opened for the first time, the cap (1) prevents the device (100) from being completely closed again on the bottle.
