Abstract: A Petri dish includes a receptacle and a matching lid, which both have a shape of revolution and are each delimited by a bottom wall and at least one peripheral rim. This also includes fingers and complementary locking elements. The receptacle and the lid, when rotated relative to each other, are able to occupy three or four different positions, including at least a “first position” and an “intermediate position”. This dish is distinguished by the fact that the locking elements carry at least one blocking member which blocks the fingers in the “intermediate position” and which opposes the return to the “first position”.

Abstract: A Petri dish has members including a receptacle and an additional lid, both having an axisymmetric shape and which are delimited by a bottom wall and at least one peripheral wall, the receptacle and lid bearing complementary lock sections so that when a stack is formed by superposing at least two dishes, borne by a first component of a first dish which can engage with the lock section of the second component of the second dish, thus making them rigidly connected to one another. These lock sections cooperate by relative rotational movement of one dish with respect to the other, the lock sections being borne by the peripheral walls and including protrusions.
