摘要

A container for storage of products in a modified atmosphere is disclosed. The container comprises a box (2) and a lid (3) which is equipped with a seal (20). The seal (20) is positioned in a peripheral groove (10) that is formed in the inner face (8) of the lid (3). The box (2) comprises an inner (5) and outer (6) flat peripheral rims and the lid (3) comprises a vertical peripheral rim (7). The vertical peripheral rim (7) of the lid (3) is designed to cover the outer peripheral rim (6) of the box (2) upon the closure of the lid (3). The inner (5) and outer (6) peripheral rims are in different planes and constitute a shouldered shape. The lid (3) further comprises step (9) between its vertical peripheral rim (7) and its inner face (8). The shape of the step (9) matches the shoulder shape of the box (3) and the distance between the plane of the step (9) and the plane of the inner face (8) of the lid (3) is less than the distance separating the planes of the peripheral rims (5 and 6) of the box (2).
