FIELD: transport; tare.
SUBSTANCE: neck has crown in its upper part, and outer screw thread and crimping part intended for crimping of the cap on side wall. The cap includes outer frame with insert containing inner head and inner skirt with inner screw thread for interaction with neck outer screw thread and sealing spacer with central and peripheral elements or flange. The insert contains device securing radial crimping of the spacer to the neck so that when the cap is winded on the neck the flange is radial squeezed between the insert and neck. Leak-proofness and winding moment in cap opening do not significantly depend on cap's axis position related to the neck.
EFFECT: higher leak-proofness of sealing and decrease of sealing time.
