Container Closing Device with Reduced Material Usage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cap designs for containers require excessive material, leading to high production costs and necessitate specific cap shapes for different container shapes, making them inefficient and costly.
Innovation Solution
A closing device with a main body and cover that are molded as a single plastic unit, featuring a hinge mechanism and reduced main body extension, allowing for snap-fit connection and adaptable to various container shapes with minimal material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the cover completely faces the main body in closed position to match container shape, then the aesthetic appearance and shape matching is improved, but the quantity of material used increases and production costs rise
Solution Approach 1:
The patent extracts the functional requirement of shape matching from the entire cover surface and applies it only to specific portions (front and/or rear portions) that need to face the container. This allows the cover to maintain adequate shape matching while using less material overall, as not all portions need to completely face the main body.
2Adaptability or versatility
If specific caps are made for different container shapes to ensure proper fit and appearance, then the adaptability to different container shapes is improved, but the manufacturing complexity and design costs increase
Solution Approach 1:
The patent designs the cover with portions that can face different directions (front, rear, or both) to universally accommodate various container shapes. This multi-functional design allows a single cap design to adapt to different container configurations without requiring completely different cap designs for each container type, thereby reducing manufacturing complexity while maintaining adaptability.

AI summary
The present invention is a closing device (1; 71; 91; 101) for a container (50; 51), comprising: a main body (2; 72; 92) suited to be connected to the container (50; 51) and comprising an opening (4) for the passage of a product flowing out of the container (50; 51); a cover (12; 82) comprising closing means (23) of the opening (4) and suited to be arranged in a closed position with respect to the main body (2; 72; 92), in which the closing means (23) intercept the opening (4), and suited to be arranged in an open position, in which the closing means (23) do not intercept the opening (4). In said closed position, at least one portion of the cover (12; 82) does not face said main body (2; 72; 92).
