Container system with base and foldable lid

A container system, comprising:

• a base having a bottom and one or more sidewalls extending from the bottom to define an interior volume, the base having a base rim having a thickness T at a peripheral edge of the one or more sidewalls, the base rim having an inner periphery substantially smoothly contoured about its entire extent;
• and
• a lid having a top surface, the top surface comprising:
• a first part having a first peripheral outer rim defining a first channel having a width t, the first channel formed by a first partial peripheral trough in the top surface radially inward of the first peripheral outer rim;
• a second part having a second peripheral outer rim defining a second channel having the width t, the second channel formed by a second partial peripheral trough in the top surface radially inward of the second peripheral outer rim, the thickness T of the base rim and the width t of the first and second channels dimensioned to releasably engage with each other in a coupling arrangement, and
• a double hinged region extending across a width of the lid between the first part and the second part, the double hinged region having a first and a second hinge extending across the width of the lid and separated by a longitudinally extending area about which the lid folds as the first part of the lid is lifted from the base to disengage portions of the base rim from the first channel and to pivot the first part to provide access to the interior volume of the base while the second part of the lid on an opposite side of the hinge remains secured and attached to the base, the first and second peripheral outer rims being discontinuous at edges of the longitudinally extending area by the base rim;
• wherein said first part of the lid contains a first land on its upper surface, said second part of the lid contains a second land on its upper surface, and wherein said first and second lands are radially inward of the first and second partial peripheral troughs and are brought in opposing proximity to each other when the first part of the lid is moved to the open position, the first and second lands having a height above the upper surface such that the longitudinally extending area provides a vertical offset in the hinged region to provide clearance for the first land and the second land when the first part of the lid is in the open position.
