Lid-container assembly made of plastic material

An assembly made of synthetic plastic material comprising a lid and a container, wherein the container comprises:

• a bottom connected with one of a substantially cylindrical side wall and a cone trunk around a longitudinal axis;
• the side wall having an upper edge defining an access opening to the container, a first external annular strip outside the side wall provided with a first circular rib and at least one second circular rib engaging the lid of the container;
• wherein the lid comprises:
• a central part and a peripheral wall that conforms with the side wall of the container and comprises a second external annular strip that releasably engages the first external annular strip of the container;
• the second external annular strip comprising an upper annular element that connects to the peripheral wall by an upper, upturned U-shaped annular channel and at least one intermediate annular element below and connected with the upper annular element by a first circular tear line;
• and wherein facing surfaces of the first external annular strip of the container and the second external annular strip of the lid comprise further opposite engaging ribs;
• wherein the assembly further comprises:
• a first interference sealing zone between opposite surfaces of the side wall of the container and of the peripheral wall of the lid;
• a second contact sealing zone between an upper edge of the container and the upper annular channel of the lid;
• and
• a third contact sealing zone between opposite ribs of the first and second external annular strips;
• and wherein the second external annular strip of the lid comprises a lower annular element that extends downwards and is connected by a second tear line to the intermediate annular element, said lower annular element of the second external annular strip of the lid, terminating with a peripheral edge configured with a rib that extends into a lower upturned U-shaped annular channel that engages a corresponding rib inside the aforesaid lower upturned U-shaped annular channel of the first external annular strip of the container.
