Cylindrical Cork with Pull Cord for Tool-Free Wine Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottle stoppers either require a corkscrew for removal or are complex and expensive, failing to provide a simple, tool-free solution for removing a cork that is slightly porous like traditional corks.
Innovation Solution
A bottle stopper formed of a thin, pliable material wound into a compact cylinder that can be easily removed by pulling an attached cord, which unfurls the band into a helical configuration, allowing it to release from the bottle neck without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional cork is used to seal the bottle, then the wine quality is preserved through minimal air interaction and proper aging, but the cork requires a corkscrew for removal which is difficult to access during outdoor activities
Solution Approach 1:
The cork is segmented into a cylindrical body and a separate pull cord. The pull cord extends through the cork and can be pulled to extract the cork without requiring a corkscrew. This segmentation allows the cork to maintain its sealing function while enabling tool-free removal during outdoor activities.
Solution Approach 2:
The pull cord acts as an intermediary mechanism that transfers force from the user's hand to the cork, enabling cork removal without direct manipulation of the cork itself. This intermediary allows easy removal while preserving the traditional cork's sealing properties.
2Ease of operation
If a screw cap is used instead of a cork, then tool-free removal is achieved, but oxygen permeation is prevented which eliminates the benefits of traditional cork aging
Solution Approach 1:
The cork is made from porous material that allows controlled oxygen permeation, enabling wine aging and flavor development. The porosity is maintained while the attached pull cord provides tool-free removal capability, combining the benefits of traditional corks with easy removal.
3Ease of operation
If prior-art corks with integral handle mechanisms are used, then tool-free removal is possible, but substantial force is required and the devices become complex with numerous expensive components
Solution Approach 1:
The pull cord is extracted as a separate component from the cork body, rather than integrating a complex handle mechanism into the cork. This extraction simplifies the overall structure, reducing the number of parts and manufacturing complexity while maintaining tool-free removal functionality.
Solution Approach 2:
Instead of integrating the removal mechanism into the cork (as in prior art), the solution inverts the approach by attaching a simple pull cord to the cork. This inversion simplifies the design from complex integrated mechanisms to a simple attached cord system.

Function Achieved in This Case
The solution enables easy removal of the bottle stopper without a corkscrew, maintaining the wine's quality by preventing contamination and absorption, while also allowing the stopper to be displayed as an inspirational banner.
Implementation Method 1
tightly wound into a compact cylinder that is dimensioned and configured to firmly seat within a bottle neck opening
Implementation Method 2
formed of a thin pliable material that is tightly wound
Implementation Method 3
prevents the cork from contaminating the enclosed wine and from absorbing the wine by capillary action
Implementation Method 4
When the cord is pulled, the band unfurls into a helical configuration that easily releases from the bottle neck

AI summary
A bottle stopper includes an elongated band formed of a thin paper, plastic, or similar material. The band is tightly wound into a compact cylinder that is dimensioned and configured to firmly seat within a bottle neck opening. Preferably, the cylinder includes an outer liner of food-grade material that prevents the cork from contaminating the enclosed wine. A cord is attached to the central core of the resulting compact cylinder and extends a predetermined distance above the bottle neck. When the cord is pulled, the band unwinds into a helical configuration that easily separates from the bottle neck.
