Abstract
A cap that is intended to obturate a duct for ejecting cartridges of a turret. This cap includes a circular base that is intended to allow it to be fastened to the duct, and a body shell having a spherical dome profile including a concave face and a convex face, the body shell being divided into at least four sectors by radial slits that are regularly distributed angularly, the sectors being contiguous pairwise. Another subject of the invention is a turret including a duct for ejecting cartridges equipped with such a cap.

A cap intended to obturate a duct for ejecting cartridges from a turret, the cap comprising:
- a circular base intended to allow the cap to be attached at the duct, and
- a shell having a spherical dome profile including a concave face and a convex face, the shell alone being divided into at least four sectors by slots which are evenly distributed angularly, the shell being cut along the slots, the sectors being contiguous pairwise and having a base of the sectors that is located on the shell,
- the cap being made of a flexible material, a natural elasticity of the flexible material ensuring that the cap is held in a closed position and a shape of the shell with the spherical dome profile ensuring that the cap returns in an obturated position after the cap has been deformed by a cartridge,
- wherein each slot is inclined with respect to a diametrical plane, the inclination being variable between a leg of the slot and an end of the slot at the vicinity of an axis of the cap, the slot being diametrically oriented at the vicinity of the axis of the cap so as to ensure the contact of the plural sectors, the inclination of the slots ensuring a partial covering of the contiguous sectors.
