Abstract
A container includes a base and a lid sealingly engageable with the base. The base includes a base hinge panel and the lid includes a lid hinge panel. The base hinge panel and the lid hinge panel are hingedly connected along a hinge line to form a foldable section. The foldable section has a first side edge, a second side edge, and a frangible line that extends between the first side edge and the second side edge. In extending between the first side edge and the second side edge, the frangible line extends across each of a portion of the base hinge panel, the hinge line, and a portion of the lid hinge panel.

A container comprising:
- a base including a base hinge panel;
- and
- a lid sealingly engageable with the base, the lid including a lid hinge panel;
- wherein the base hinge panel and the lid hinge panel are hingedly connected along a single hinge line to form a foldable section, the foldable section having a first side edge, a second side edge, and a frangible line that extends from the first side edge to the second side edge and, in extending from the first side edge and to the second side edge, the frangible line extends within a portion of the base hinge panel to the hinge line, across the hinge line, and within a portion of the lid hinge panel from the hinge line.
A container comprising:
- a base including a base rim extending about a peripheral portion of the base;
- a lid including a lid rim extending about a peripheral portion of the lid, the lid rim sealingly engageable with the base rim to seal the lid and the base;
- a base hinge panel extending outwardly from the base rim and having a first side edge and a second side edge;
- a lid hinge panel extending outwardly from the lid rim and having a first side edge and a second side edge, the lid hinge panel being hingedly connected to the base hinge panel along a single hinge line;
- and
- a frangible line extending from the first side edge of the base hinge panel to the second side edge of the lid hinge panel, the frangible line extending within a portion of the base hinge panel to the hinge line, transecting the hinge line, and extending within a portion of the lid hinge panel from the hinge line.
A container comprising:
- a base including a base rim extending about a peripheral portion of the base, the base rim including a base rim bead having an inner wall and an outer wall joined by a bottom segment;
- a lid including a lid rim extending about a peripheral portion of the lid, the lid rim including a lid rim bead having an inner wall and an outer wall joined by a bottom segment, wherein the inner wall and the outer wall of the lid rim bead frictionally engage the inner wall and the outer wall, respectively, of the base rim bead to sealingly engage the lid rim and the base rim;
- a base hinge panel extending outwardly from the base rim;
- and
- a lid hinge panel extending outwardly from the lid rim, the lid hinge panel hingedly connected to the base hinge panel along a single hinge line to form a foldable section that includes the base hinge panel, the hinge line, and the lid hinge panel, the foldable section having a first side edge, a second side edge, and a frangible line that extends from the first side edge to the second side edge and, in extending from the first side edge and to the second side edge, the frangible line extends within a portion of the base hinge panel to the hinge line, transects the hinge line, and extends within a portion of the lid hinge panel from the hinge line.
