A sales jug of thermoplastic material has a sealing lid (14) which is secured by a very firm snap locking engagement with a groove (6) in the edge portion of the jug, while the lid is adapted to be opened by means of a rupture arrangement inside the snap locked edge portion thereof. For stabilizing the locking engagement the lid is provided with an upstanding edge flange (24), which is rested laterally against a corresponding upper and outer annular flange portion (12) of the jug. The upstanding edge flange (24) of the lid is extended outwardly and downwardly about the top edge of the said annular flange (12) of the jug, whereby this flange is stabilized against a release of the snap lock arrangement. The outermost portion of the extended lid edge flange serves to hold a skirt portion of a reclosing lid (42). The sealing lid together with the reclosing lid may be mounted automatically on the jug by means of a high pressing force, whereby a firm snap locking is achievable even with a relatively short locking displacement of the sealing lid, and when this displacement is short, the liquid filled jug may be closed and sealed practically without any air remaining trapped therein. |
