Abstract
This assembly includes a tubular body and a cap attached to the tubular body to define a chamber for an active material. The tubular body includes a transverse wall and a peripheral wall and the cap includes a base wall and a side wall. The chamber is delimited by a part of the tubular body including the transverse wall and is closed by the cap. The side wall of the cap on its periphery includes a plurality of longitudinal features in relief which cooperate by mutual engagement with complementary longitudinal features in relief provided on the peripheral wall of the tubular body substantially parallel to its longitudinal axis (X2).
