Abstract

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.
