Hinged Bottle Safety Lid With Retention Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle lids with hinged closure caps are uncomfortable to drink from due to lack of means to retain the closure cap in an open position and have unclear visual indicators of tampering, with frangible means being difficult to detect and prone to interference during use.
Innovation Solution
A safety lid with a protrusion that allows the closure cap to be opened beyond 180°, providing an acoustic signal and stable retention, and a breakable flange indicator located on the front for clear visibility of opening, combining bending and traction forces for deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the closure cap is hinged to the pouring element without retention means, then the lid allows easy opening and closing, but the closure cap cannot be retained in the open position making it uncomfortable to drink from
Solution Approach 1:
The protrusion is pre-positioned on the closure cap to engage with the pouring element when the cap is opened, automatically providing retention without requiring additional active components or user intervention to maintain the open position
2Reliability
If frangible means are used as opening indicators, then they provide tamper evidence, but they are difficult to detect visually and prone to interference during use
Solution Approach 1:
The front face of the closure cap is designed to change from an intact smooth surface to a broken fragmented surface upon opening, creating a stark visual contrast that immediately signals tampering or opening to the user
Solution Approach 2:
The opening indicator is moved from the traditional location on the sealing surface or side to the front face of the closure cap, transforming it into a highly visible focal point that is difficult to miss during normal viewing angles

AI summary
Safety lid for bottles, comprising a pouring element (1) that can be attached to the neck of a bottle, a closure cap (2) attached to the pouring element (1) through a rear hinge (3), a flexible protrusion (5), located in its part closest to the pouring element (1), which contacts the pouring element (1) in the open position, and two lateral flanges (7). The lid comprises a first opening indicator element located in the space delimited between both flanges (7), consisting of a flange comprising a first sector (12) attached to the pouring element (1), a second sector (13) attached to the closure cap (2), and a breakable central sector (14) that allows a break and separation of the flange when a first opening of the lid occurs and a subsequent torsion deformation of the first sector (12) and the second sector (13) of that flange.
