Bottle Closure Device with Perforated Peripheral Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic product bottles face issues with moisture accumulation, mildew proliferation, and difficulty in handling due to their weight and design, leading to poor hygiene and increased production costs.
Innovation Solution
A lightweight closure device with perforations on its peripheral portion that can be screwed onto or pressed onto the bottle neck, featuring a hinged tag for easy access and aesthetic appeal, allowing water drainage and providing a secure grip, made from water-resistant materials like ABS or PP.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the closure device structure is lightened to reduce production costs, then manufacturing costs decrease and ease of molding improves, but structural strength and sealing reliability may deteriorate
Solution Approach 1:
The closure device utilizes a thin-walled structure with integrated peripheral portion that flexes to engage with the bottle neck. The peripheral portion acts as a flexible sealing element that deforms to create a tight seal without requiring thick walls or complex reinforcement structures, thus maintaining strength while enabling light weighting and ease of molding.
Solution Approach 2:
The invention merges the closure body and peripheral sealing portion into a single integrated structure. This consolidation eliminates the need for separate sealing rings or gaskets, reducing the number of parts and material usage while maintaining both sealing reliability and structural integrity through the unified design.
2Weight of moving object
If the closure device is made lightweight to reduce production costs, then total package costs decrease, but handling ease and grip comfort may worsen
Solution Approach 1:
The peripheral portion is designed with a curved, substantially circular cross-section that conforms to the contours of human fingers. This ergonomic curvature provides natural grip points and distributes holding pressure evenly, improving handling comfort despite the reduced weight and thinner wall structure of the lightweight closure device.
3Ease of manufacture
If the closure device structure is simplified to reduce costs, then production costs decrease, but aesthetic appearance and user perception may deteriorate
Solution Approach 1:
The peripheral portion serves multiple functions simultaneously: it provides sealing against the bottle neck, acts as a gripping surface for handling, and functions as an aesthetic decorative element. This multi-functionality allows a single simplified structure to meet diverse requirements including cost reduction, functional performance, and aesthetic appeal without needing additional ornamental components.

AI summary
A closure device (10) for bottles, for example containing cosmetic products, comprising a main body (11) with a first portion (11a) coupled to a threaded neck of the bottle or inserted with pressure into the bottle's neck and a second portion (11b) that has at least one hole or opening (12) for discharging the product; between said first (11a) and second portion (11b) of the main body (11) there is a peripheral portion (14), which extends externally to the first portion (11a), so as to entirely lean against an external wall of the bottle, and on which there are formed one or more holes, slits or shaped through-openings (15).
