Closure vent for tamper evident container

A plastic food container capable of assuming a loading state and an initially sealed state in which the container rims are engaged, the container comprising:

• a base and a lid;
• the base having a base rim peripherally encompassing the base and the lid having a lid rim peripherally encompassing the lid;
• hinge-forming structure extending from a first hinge-joining section of the lid rim to a second hinge-joining section on the base rim;
• in the initially sealed state the first hinge-joining section superposing over all or part of the second hinge-joining section, the area at which the first hinge-joining-section superposes the second hinge-joining section defining an overlapping portion of the first and second hinge-joining sections on the engaged rims;
• the lid rim having a lid retaining bead, the lid retaining bead having a peripherally projecting bottom segment, a peripherally projecting lid rim flange and an outer vertically oriented segment disposed between the peripherally projecting horizontal segment and the peripherally projecting lid rim flange;
• the base rim having a base retaining bead, the base retaining bead having a peripherally projecting platform segment, a peripherally projecting top segment and an inner vertical wall disposed between the peripherally projecting platform segment and the peripherally projecting top segment;
• in the initially sealed state the base rim and lid rim frictionally engage each other such that;
• the peripherally projecting bottom segment of the lid rim and peripherally projecting platform segment of the base rim contact each other and form a first proximal seal zone;
• and
• the outer vertically oriented segment of the lid rim and the inner vertical wall of the base rim contact each other and form a second proximal seal zone;
• one or more vent channels formed in either of the lid rim or base rim and located within the overlapping portion;
• and
• when the container is in the sealed state, the one or more channels form a complete discontinuity in the first proximal seal zone and in the second proximal seal zone.
