Abstract (en)
A pilfer-proof plastic closure comprising a top panel wall (4) and a cylindrical skirt wall (6) extending downwardly from the peripheral edge of the top panel wall (4). The skirt wall has formed therein a circumferentially extending breakable line (16) dividing the skirt wall into a main portion (12) above the breakable line and a pilfer-proof bottom portion (14) below it. The main portion (12) has formed on its inner surface an internal thread (24) and the pilfer-proof bottom portion has formed on its inner surface a plurality of radially inwardly projecting engaging flaps (26) at circumferentially spaced positions. Each of said engaging flaps (26) has a first portion (32) extending from the inner surface of the pilfer-proof bottom portion and a second portion (34) extending further from the forward end (30) of the first portion (32) inclinedly to the first portion in the closing direction of the closure for mounting the closure on the mouth-neck portion. An axial breaking line (48) is formed in the pilfer-proof bottom portion (14) which extends downwardly from the upper end of the pilfer-proof bottom portion but is non-existent in at least a greater portion of the lower part of the pilfer-proof bottom portion. At least a greater portion of the base edge (28) of each of the engaging flaps is positioned in the aforesaid lower part where the axial breaking line (48) does not exist.
