Closure Device Anchor Ring Tearable Web Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure devices for containers require excessive force or tools to open due to the presence of non-tearable webs between the closure cap and anchor ring, making them uncomfortable and inefficient for consumers.
Innovation Solution
A closure device design featuring a closure cap connected to an anchor ring via a connecting element, with a guide mechanism allowing rotary movement and incorporating a tearable bar that detaches during the initial opening, reducing the need for excessive force and enabling easy opening by tearing the tearable web.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tearable webs are arranged between the closure cap and anchor ring to prevent loss, then reliability is improved, but ease of operation deteriorates due to excessive tearing force required
Solution Approach 1:
The connection between closure cap and anchor ring is segmented into two distinct elements: a permanent connecting element that prevents loss and a separate tearable web that enables easy opening. This segmentation allows each element to fulfill its specific function without compromising the other.
Solution Approach 2:
The tearable web acts as an intermediary element between the closure cap and anchor ring, providing a sacrificial connection that can be easily broken while the permanent connecting element remains intact to prevent loss of the closure cap.
2Reliability
If non-tearable webs are used between closure cap and anchor ring to ensure permanent connection, then reliability is improved, but ease of operation worsens due to difficulty in opening
Solution Approach 1:
The connection system is divided into permanent and temporary connection elements, where the permanent connecting element ensures reliability while the temporary tearable web enables easy opening operations.
Solution Approach 2:
The connection characteristics change dynamically during use: initially providing strong permanent connection, then allowing easy separation through the tearable web after first opening, adapting to different operational phases.
3Reliability
If multiple tearable webs are arranged between anchor ring and guarantee ring for security, then reliability is improved, but device complexity increases
Solution Approach 1:
Multiple tearable webs connecting the anchor ring to the guarantee ring are merged into a single integrated structure, maintaining the security function while reducing component count and simplifying the overall device design.

AI summary
A closure device (1) for closing a container comprising a closure cap (2) with a cap lid (3) extending radially to a closure axis (50) and a cap mantle (4) extending axially and circumferentially to the cap lid, an anchor ring (5), a guarantee ring (6) and a connecting element (7), wherein the closure device (1) is designed and connectable to a closure base (8) such that the closure cap (2) selectively closes an opening of the closure base (8) by a closing movement or releases it by an opening movement and that the anchor ring (5) remains engaged with the closure base (8) both in an open position of the closure cap (2) and in a closed position of the closure cap (2), wherein the connecting element (7) connects the closure cap (2) to the anchor ring (5).
