ABSTRACT:
A plastic container for storing fluids having a neck (3) with an opening closed by means of a plastic cover (4) is disclosed. An annular portion of the cover (4) surrounds the neck (3) thus providing an inner rim (9) and an outer rim (8) in the cover (4). A first gasket (7) inserted between these rims is pressed against the upper edge of the neck (3) and a second radially and axially supported gasket (10) between the cover (4) and the neck (3) are compressed under the action of a means for biasing the cover (4) toward the neck (3) to seal the cover on the container. Means are provided to limit the motion of the cover (4) axially towards the neck (3) to prevent the first gasket (7) from being damaged.
