FIELD: manufacturing technology.

SUBSTANCE: disclosed a closure assembly consisting of glass container (50) with outwardly displaceable circumferential thread elements (54, 55) on neck (52) of the glass container and the tamper closure, note here that said closure (1, 2) comprises, on its inner side, circumferential plastic layer (30; 30h, 30v). Sealing cover is pressed on container neck (52) and opened by rotary movement through thread elements (54, 55) and vertical section (30v) of plastic layer. Container neck (52) comprises horizontal end surface (52) to which horizontal section (30h) of plastic layer adjoins under pressure to form a seal. Central area (11) of the sealing closure passes over the adjacent transition-oriented transition zone (11a, 11b, 11c) into the axially protruding section (12) of the skirt, which ends in sealing area (21a, 21; 22). Layer (30; 30h, 30v) of plastic is located with clutch on inner side of cover on transition zone (11a, 11b, 11c) and section (12) of skirt. Axial length (h₀) of skirt portion (12) and radial dimension (b₅₂) horizontally oriented end surface (52a) of neck (52) of container form first ratio (v₁), which is less than three.

EFFECT: closure assembly is disclosed.
