A packing ( 2 ) of plastic material, including a container body ( 4 ) with associated lid ( 6 ), where the screw cap includes closing means preferably in the shape of projecting parts ( 28 ) on a downwards projecting, annular section ( 34 ) on the periphery of the cap, which interact with open, sloping grooves ( 22 ) on the outer side of the mouth ( 8 ) of the container body. The peculiar feature of the packing ( 2 ) is that the screw cap ( 6 ) has a "click" function, as the sloping grooves ( 22 ) and the projecting parts ( 28 ) have interacting locking means that are arrested in each other by screwing on the lid ( 6 ) on the mouth ( 8 ) of the container body, so that relevant parts ( 46 ) on the underside ( 11 ) of the lid in the screwed position of the cap are pressed with a certain fore against the rim area 20 of the mouth of the container ( 8 ).
