Abstract (en)
[origin: EP0525276A1] It is foreseen a button formable for initial setting out, on the hollow bottom of a boasting face (1) of a thermoplastic seal with central separator part (2), with upward balanced curvature, for obstructing the opening (3) of the same bottom. Said seal comes out from said opening (3) with pressing notckes system (4) determining a surface radial pattern (5) on the same plane, insisting on cloth to protect it from driving effect in fabrication phase and to permit the button permanent junction, centrally forming the centring structure (6) to direct the nail penetration. Said seal is held on bottom from its superior bucket part (7) with radial holding on the initial wall part. On the upper part the toothed form (8) of the alloy core base (9) determines an overall constraint seat making by channel (10), with initial conversion hollow to act as guide for nail penetration, and by terminal (11), with spherical sector in introduction wider than said channel, to permit during the nail sharp hollow part (12) deformation the bloxking realization by its incorporation being impossible the interchange for unthreading. The button completion is attainable by cap (13) application. <IMAGE>
