Thermoplastic material token for thermoforming of container, comprises punt part having central part with plane and parallel faces of pastille and peripheral part having plane and parallel faces of annular flange

摘要

The faces of the central and peripheral parts are perpendicular to the axis of symmetry of the pastille and the flange. The peripheral part (10B) is connected to the central part (10A) through faces (11A, 11B). Concave and convex arcs of circles are located at the side of (10B) and (10A). The thickness of (10B) is 0.4-0.6 times thickness of (10A). The height of the withdrawal more marked is 2.5-3.5 times height of the withdrawal less marked. The width of the withdrawal less marked is lower than the width withdrawal more marked. The multilayer token has thermoplastic and light/gas barrier layers obtained by molding, cutting and machining.
