AI Technical Summary

Technical Problem

Existing sealing bodies for containers fail to maintain an open-hold arrangement after opening, hindering pouring or drinking operations and lack control over the connecting chain deployment.

Method used

A sealing body with a connecting chain defined by cut lines that allows controlled deployment, enabling the sealing body to move into an open-holding position relative to the container mouth, using a single molded body with non-converging cut lines and destructible bridging portions to ensure the safety ring remains attached.

Benefits of technology

The sealing body achieves an open-hold arrangement where the open end faces the container mouth, allowing unhindered pouring or drinking, while maintaining the safety ring attached, with controlled chain deployment and tamper-proof functionality.

Abstract

A seal having an annular skirt (10), a safety ring (8), and an annular side wall (6) having a first connecting chain (12) and a second connecting chain (14) defined by a first notch (30) and a second notch (50) that do not converge to each other, and permanently connecting the annular skirt (10) and the safety ring (8). The annular skirt (8) is provided with an internal thread or projection (18) that defines a rotation (LR) in the release direction on a reference axis (A) defined by the safety ring (8). At least within the region of the connecting chains (12, 14), the orthogonal projections in the direction of the reference axis of the notch line overlap and define the first connecting chain (12) and the second connecting chain (14) extending in the release direction (LR) from each corresponding first connection region (12-1, 14-1) integrated with the safety ring (8) to each corresponding second connection region (12-2, 14-2) integrated with the annular skirt (10).
