ABSTRACT:
A freshness-preserving container is disclosed. The container includes a lid and a base which are connected and which pivot about a hinge line along their rear walls. The front wall of the lid has an inward facing surface disposed toward an outward facing surface on the fornt wall of the base. Between the inward and outward facing surfaces is a freshness-preserving element for preserving the freahness of the contents of the container. The freshness-preserving means includes a flap mounted on either the lid or the base which engages a shoulder on the other part of the container. As the container closes, the flap slides across the shoulder effecting a latch closing and making a clicking sound indicating the freshness-preserving characteristics of the container. An adhering element also may be provided, such as tape or magnetic pieces, for resealing the container when it is closed. In addition, the lid may overlap the base of the container, further contributing to its freshness-preserving characteristics.
