The ashtray has a fireproof housing (1) with an opening with a fireproof lid (2). The opening is round and is hermetically sealable by a seal (8) which is joined to the lid or the housing. The lid is sprung and pivots relative to the housing and is lockable in the closed position. The air pressure within the housing is lowered by a suction device. The suction device is an electric pump (4), powered by batteries or an accumulator (6) charged by solar cells. The pump is actuated by the closure of the lid which is relayed via a mechanical or optical switch and operates for a pre-set or variable time period. The exhaust from the pump passes through a filter.
