摘要

The lid (30) has a groove located in a lower surface of the lid and separating the lid into two parts (30A, 30B), where the part (30B) is integrally connected to an upper opening of a cubic container (40). The part (30A) is pivoted along the groove towards top and bottom. A complementary projection (34A) and a complementary notch (34B) are located on opposed sides of the parts. The projection is engagable with frictions in the notch for maintaining the part (30A) in an opening position when the part (30A) is pivoted in the direction of the opening.
