<p>A bucket with a lid solves the problem of designing a sealing element for notifying the first opening of the lid and protecting the lid from getting off during transport. A container of arbitrary shape (1) whose free edge has a sealing flange (2) over which is placed the lid (3) with its rim (4) and with a reinforcing holding ring (6) placed under the flange (2). The ring (6) has a cross-section in the form of letter L turned upside down, where on the upper side of the annular wall (9) of the ring (6) a positioning ring (10) is foreseen, while on the ring (6) a hollow (12) is made so that the upper wall (9) of the ring (6) is sunk into it to approximately half of the ring(6) height, and is from the front side closed by sealing plate (13) connected to the hollow (12) through sealing bridges (14).</p> |
