Abstract
A portable object includes a case forming a housing inside which is arranged a device that requires air to operate, and a closure device including at least one permeable element. The closure device is arranged to provide impermeability to liquids while allowing the atmosphere inside the housing to communicate with the external atmosphere. The case comprises a recess in which a through opening is made, the recess being closed by the closure device. The closure device includes a permeable module mounted to move such that, in a gaseous environment, the permeable module is in a rest position allowing gases to penetrate the case opening through the permeable module, and in a liquid environment, the permeable module is in an operating position in which gases and liquids are blocked. The permeable module comprises a tubular support at the end of which is fixed a membrane.
