Solution Overview

Problem

Existing closures for containers, such as plastic bottles, tend to be completely removable after opening, leading to misplacement and interference with the bottle aperture during use, and result in waste if not recycled.

Innovation Solution

A tethered stopper system where the closure shell remains attached to the tamper band, allowing it to be secured away from the bottle aperture, preventing interference and enabling multiple uses without complete removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the closure shell is made completely removable from the bottle, then the ease of operation is improved, but the closure shell may be misplaced or interfere with the bottle aperture during use

Engineering Contradiction:
Improveease of openingVSAvoidinterference with bottle aperture
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The closure system is divided into separate components: the closure shell that can be opened and removed for access, and the tamper band with retention features that remains on the bottle. The strip connects these components, allowing the closure shell to be partially removed while maintaining connection through the retention features on the transport ring, thus preventing misplacement and interference.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the closure shell is completely removed after opening, then the ease of operation is improved, but waste is generated if not recycled

Engineering Contradiction:
Improveease of removalVSAvoidwaste of closure shell
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The closure system separates the closure shell from the retention mechanism, allowing the closure shell to be easily removed for use while the tamper band with retention features remains on the bottle. The strip maintains connection between components, enabling the closure shell to be reused by reattaching it to the retention features, thereby reducing waste.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If a tethered stopper with spiral strip is used, then the closure shell remains connected to the bottle, but the elastic properties cause the strip to return to original configuration and the closure shell may still interfere with the bottle aperture

Engineering Contradiction:
Improveconnection between closure and bottleVSAvoidinterference with bottle aperture
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The system divides the connection mechanism into a strip component and a retention feature component. The retention features on the transport ring provide fixed attachment points that prevent the closure shell from returning to interfere with the aperture, while still maintaining connection through the strip.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The retention features on the transport ring act as intermediaries between the strip and the closure shell, providing fixed attachment points that control the position of the closure shell and prevent it from interfering with the bottle aperture while maintaining the connection.

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The tethered stopper system effectively prevents the closure shell from being misplaced and ensures it remains out of the way during use, allowing for repeated securement and removal, reducing waste and user inconvenience.

AI summary

The present invention discloses a tethered stopper affixed to a bottle neck finish. The stopper includes a closure shell, a tamper band, and a strip connecting the closure shell to the tamper band at the perimeter of both the closure shell and the tamper band. The bottle neck finish includes a transport ring having a retaining feature configured to receive and retain the strip of the stopper when the closure shell is removed from the bottle neck finish. Also discloses is a method for securing the tethered stopper within the tamper band.
