FIELD: packages, particularly sealing means thereof. ^ SUBSTANCE: locking device comprises cylindrical tube having flange in low side part thereof. Flange is made as system of parallel spaced apart rigid flat streamlined plates having round areas adjoining tube side and enclosing the tube. The plates are rigidly connected to outer tube surface and to flat surface extending along axis of flange symmetry beyond side tube surface. Low part of connection flange surface extending outwards streamlined plates has depression located between low and adjacent plates. ^ EFFECT: increased quality and reliability of packing container, improved welding of package material to flange material without welding equipment complication and without additional inputs due to prevention of connection flange surface material pressing out of connection. ^ 4 cl, 3 dwg |
