Abstract

The shutoff member - for screwing onto the neck C of a bottle having a male thread 5 and an annular bead R beneath the said thread - comprises, between the internal thread 3 and the rim 7A of the side wall 1B - 7 a roughly rectangular portion 9 extending through an arc of about 140 degree and connected along the upper edge by easily breakable narrow bridges 14 and at the sides in an intermediate position by thicker side bridges 12 and comprising in the centre an internal bead 16 with an outward bevel 16B so as to pass over the said bead R of the bottle neck when screwed on, and with an almost square inward profile 16A designed to oppose the lower wall R2 of the annular bead R on the neck of the bottle; during unscrewing, the said narrow bridges 14 break and the said portion 9 tilts about the said side bridges 12 until possible breakage of one of them.
