CAP FOR CONTAINERS

摘要

The invention relates to a cap for containers designed to contain a mixture to be produced from two components. Said cap comprises a cylinder (5) with an open end and an end closed by means of a partition (6) which can be perforated. A piston (1) with a gripping member (2) having a diameter bigger than that of the cylinder is introduced in the open end so as to form a first chamber (K1) having a height h, between a lower side (KU) opposite the gripping member (2) and the partition (6). In order to prevent an unintended lowering of the piston (1), two opposite cuts (7) extending from the open end are provided in the cylinder wall, and the gripping member (2) is configured so as to be able to slide in the cuts (7) in order to move the piston (1) towards the partition (6).
