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”.
