摘要：FIELD: manufacturing technology.SUBSTANCE: invention describes repeatedly closed fitment for container with a function of its opening, having lower part (2), where cutting element (3) is installed. Due to interaction of dog (42) in closing screw cap (4) with dog (32) in cutting element (3) at first opening moves in lower part (2) to its end position. Sealing device is equipped with at least one first not allowing rotation of retainer (5, 50) which cutting element remains in its final position and cannot move upward again randomly at opening of screw cap or move down as a result of any relative displacements of both parts and fall in container. First retainer (5) which does not allow rotation is formed by rib (50) with inner side of nose (20), interacting with a groove in form of flattening (35) on cutting element (3). Additionally, second retainer (5) which does not all rotation can be provided, formed by thrust ledge (52), which is located at output end (51) of internal thread (24) of nose (20) and resting against inlet end (36) of external thread (31) of cutting element (3).EFFECT: when using both retainers (5) which prevent rotation, fixation of cutting element (3) in lower part (2) is provided simultaneously with geometrical closure and force closure.4 cl, 3 dwg
