A reclosable plastic container is formed having a cover hingedly attached to a base and having an interlocking structure such that the cover is held onto the base when the container is closed. The interlocking structure includes a locking mechanism for attaching a hinged cover to the container base in a positive-manner so that the cover will not open upon impact, but may conveniently be opened and closed when required. The locking mechanism includes a locking tab hingedly connected to the cover and an outwardly extending projection formed on the base in direct alignment with the locking tab.

A reclosable thermoplastic container comprising: (a) a base having a plurality of upright side walls with a peripheral edge extending outwardly from a side wall; (b) a cover having a peripheral edge and adapted to close upon and cover the base; (c) a positive locking tab attached to the peripheral edge of the cover by a first hinge having a first flexible line of weakness, the locking tab including downwardly depending straps joined together by a bridging member, wherein the straps and bridging member together define a U-shaped grasping handle and the bridging member defines a first camming surface; and (d) a locking catch extending from a base side wall in corresponding alignment with the locking tab wherein the locking catch is provided with a second camming surface located substantially below and inwardly toward the base side wall from the peripheral edge which is adapted to positively engage the first camming surface of the locking tab such that when the cover is in closed position on the base, the first camming surface of the locking tab engages the second camming surface of the locking catch to prevent the locking tab from returning to an unlocked position without assistance; and wherein a section of the hinge closely underlies the base peripheral edge, when the first and second camming surfaces are engaged, to resist upward forces transmitted from the cover.
