摘要

The packaging body (1) is provided with an outwards turned rounded perimetral ear rim (3). The lid has an internal perimetral housing (4) formed between two parallel concentric walls (5a,6). One wall (5a) corresponds to a first portion of the lid external lateral wall and the other is obtained as a result of the depression made on almost all the lid base. Protuberances (7) on the internal face of the lid external wall are located immediately under the edge of the body rim when the lid is closed.
