FIELD: packaging industry. ^ SUBSTANCE: invention relates to the barrels of synthetic material with the removable lids. The barrel with the removable lid contains the metal clamp ring to affix the lid to the barrel edge. When closed, the clamp ring which is U-shaped in cross-section, wraps the upper lid edge by its upper flange, and with its lower flange wraps the lower circular contact surface, that is located perpendicular or at an angle to the longitudinal barrel axis, of the barrels body bumper, which is placed under the upper barrel edge and corresponds to the upper bend limitation on the upper barrel body. The lid margin formed by the inner belt, outer belt and the connection ring, has the U-shaped downwards open lateral section with filling. When the lid is closed, the filling is pressured to the upper lid margin by clamping effort of the clamp ring. At the connection flange which connects the upper and lower flanges of the clamp ring, the ring boss directed radially inside is mould. When the clamp ring is closed, the ring boss is inserted into the closing groove in the external lid belt. ^ EFFECT: tightness of the fallen closed barrel is increased. ^ 3 dwg |
