Abstract

Il coperchio in argomento è costituito da un cappuccetto metallico in lamiera stagnata oppure in alluminio, comprendente un pannello circolare (1), munito di un bordo discendente (2) ed avente, sulla sua periferia interna, un canaletto circolare che porta una guarnizione di chiusura (3) in materiale resinoso.Il coperchio possiede una rientranza circolare (4) nella quale si trova un orifizio (6). Questo orifizio viene otturato, nella sua parte inferiore, da una membrana (10) in composto resinoso e, sulla sua superficie superiore, da un blocco di materiale resinoso che è collegato con la membrana attraverso l'orifizio (6), per formare insieme una tenuta staccabile (5), sulla regione della rientranza (4). Il materiale composto a base resinosa viene applicato allo stato liquido e fuso nella regione della rientranza (4), in maniera da penetrare nell'orifizio (6) dove esso si collega con la membrana (10) formando un'asta (11). L'aderenza e la solidificazione del materiale resinoso vengono realizzate per vulcanizzazione.The lid in question consists of a metal hood in tin-plated sheet or in aluminum, comprising a circular panel (1), equipped with a descending edge (2) and having, on its internal periphery, a circular channel that carries a closing gasket (3) in resinous material.The lid has a circular recess (4) in which there is an orifice (6). This orifice is blocked, in its lower part, by a membrane (10) in resinous compound and, on its upper surface, by a block of resinous material which is connected with the membrane through the orifice (6), to form together a detachable seal (5), on the region of the recess (4). The resin-based compound material is applied in the liquid state and melted in the region of the recess (4), so as to penetrate the orifice (6) where it connects with the membrane (10) forming a rod (11). The adhesion and solidification of the resin material are carried out by vulcanization.
