Closure device, particularly for a battery compartment

摘要

A closure device, particularly suitable to isolate a compartment (2) for batteries (3) suitable to power an electronic device (4), which is constituted by a cylindrical ring (6), with which a containment tray (8) for the batteries (3) is axially associated or monolithically coupled. Liquid-tight means (11) are provided perimetrically on the outer lateral surface (9) of the cylindrical ring (6) and interact with a complementarily shaped seat (12) formed in a protective cover (13) for the battery compartment (2).
