Container closure assembly

Abstract

The subject of the application is a container closure assembly, especially for storing substances requiring hermetic closure, made of polyethylene terephthalate screwed onto the neck of the container, which is a sleeve nut with internal thread, a break ring and a coiled cord placed between them, characterized in that the sleeve element (4) of the nut (1) in its lower part ends with a ring element (10) with an arc-shaped shoulder (11), one side of which passes into the first end of the cord (2) permanently connected to it, the other end of which passes into the upper arc-shaped shoulder (13) inseparably connected to the break ring (3), and furthermore the cord (2) is releasably connected to the lower face of the ring element (10) and to the break ring (3) by means of break elements (15) evenly distributed on its lower and upper surfaces and located opposite each other,wherein the minimum length of the cable (2) equipped with breaking elements (15) is the sum of the height of the neck (18) of the container (19) measured from its upper face to its conical shoulder (24) and the height of the nut (1), while the bottom of the nut (1) on its outer surface has an annular shoulder (7) with an inner diameter slightly larger than the outer diameter of the upper face of the neck (18) of the container (19), and next to the annular shoulder (7) there is a profile element with sharp edges and a sharp top.,
