AI Technical Summary

Technical Problem

Existing hook closure systems face challenges with retention force, oversizing leading to user experience issues, increased material consumption, and reproducibility problems due to manufacturing constraints and raw material shortages.

Method used

A retaining device with a specific geometry featuring a base and retaining elements with rods and heads, where the head is inscribed in a smaller circle tangent to the rod, reducing material deformation and enabling production from a wider range of materials, enhancing reproducibility and retention force.

Benefits of technology

The solution provides improved retention force, reduced material consumption, and enhanced reproducibility while maintaining flexibility for applications like hygiene products, addressing manufacturing constraints and raw material shortages.

Abstract

Improved retaining device Retaining device (1) comprising a base (10), a plurality of retaining elements (20) comprising a rod (30) surmounted by a head (40); wherein, for each retaining element (20), in projection in a plane formed by the upper face (12) of the base (10), the lower end (34) of the rod (30) is inscribed in a first circle C1 with center O1, the head (40) is inscribed in a second circle C2 with center O2, said second circle being tangent to one end of the head (40) in the longitudinal direction (MD), such that the second circle C2 is included in the first circle C1, the maximum dimension of the head (40) passing through the center of the circle C2 and extending in the longitudinal direction (MD) and / or the transverse direction (CD) is less than 80% of the diameter D2 of the second circle C2.
