Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing closure systems for containers are prone to accidental opening during transport and lack controlled opening mechanisms, leading to potential leakage and contamination risks.

Innovation Solution

A closure system featuring a cap with a preferential separation zone and guiding/coupling means, including a displaceable insert with a thread that forms a counterthread on the cap, ensuring controlled movement and re-closability, and a mechanical weakening notch for guided separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a hermetic closure with a breaking point is used to enable easy opening, then ease of operation is improved, but reliability deteriorates due to risk of accidental opening during transport

Engineering Contradiction:

Improveease of openingVSAvoidresistance to accidental opening

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The closure system is divided into distinct functional segments: a hermetic seal portion for maintaining integrity during transport, and a controlled opening mechanism with guiding means that segments the opening action into controlled steps rather than a single breakable point

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Guiding and coupling means act as an intermediary mechanism between the cap and container body, providing controlled movement guidance that mediates between the user's opening action and the hermetic seal, preventing accidental disengagement while enabling intentional opening

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If a single application force is used to open the container quickly, then productivity is improved, but object-affected harmful factors worsen due to potential leakage and contamination

Engineering Contradiction:

Improveopening speedVSAvoidleakage and contamination risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The guiding and coupling means perform preliminary actions by guiding the cap's movement along a predetermined path before complete separation occurs, ensuring the opening process is controlled and directed rather than sudden and uncontrolled

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The opening mechanism transitions from a static breakable point to a dynamic controlled movement system where the cap moves along a guided path, allowing the opening process to be controlled through motion constraints rather than relying on a single force application

Inventive Principle:

Principle #15Dynamics

AI summary

A closure system and method of forming containers comprising a closing element. The closing element is integrally sealable to the container at one of the openings to be closed, and a preferential separation zone between the container and the closing element, the closure system comprising a first guiding and/or coupling portion for guiding and controlling the movement of the closing element from a first blocking position, wherein the closing element is integral to the container, to a second unblocking position, wherein the closing element is separated from the container via the preferential separation zone. The closure system further includes a first thread on the insert and a second thread formed within the closing element.
