Abstract (en)
[origin: US5074428A] Such synthetic resin lids comprise an outer rim (4) encompassing the barrel neck (3) and an inner rim (5) entering into the barrel neck (3) and projecting beyond the lid bottom (6) below the barrel opening, as well as a sealing ring inserted between the outer rim (4) of the lid and the inner rim (5) of the lid. This sealing ring is urged by means of a clamping ring (10) or tightening wire against the opening rim (14) of the barrel neck (3), the clamping ring (10) or tightening wire extending over a flange (110 or flange sections molded to the outer rim (4) of the lid at the bottom and extending underneath a solid border (120 which latter protrudes radially toward the outside at a spacing below the barrel opening from the barrel wall. This border can be designed as a continuously extending flange or can be subdivided into flange sections. An axially projecting annular web (8) is molded to the base of an annular chamber ( 7) formed by the outer and inner rims (4 and 5, respectively) of the lid. This annular web, when the lid (1) is closed, transmits axial forces caused by stacking, dropping, etc. directly into the barrel neck (3). Sealing rings (13) are arranged on both sides of the annular web (8) which rings, when the lid (1) is closed, rest with pretensioning on the opening rim (14) of the barrel neck (3).
