Abstract
An ash tray having fire protecting activity and comprising an ash tray body (2) including an ash container (24) and an internal or external time delay circuit which is connected to an acoustic and/or optical alarm and supervising means. The ash tray is formed with a lid (3) which is normally intended to be closed, whereby the time delay circuit (25) and any other units connected thereto are disconnected but which upon opening of the lid actuates the time delay circuit, whereby the time delay circuit provides an alarm signal unless the lid (3) is closed before a predetermined set time delay has passed to an end. The lid (3) preferably is actuated by a spring (16) which tends to open the lid and against the action of which the lid can be closed, whereby the time delay circuit (25) and the alarm means connected thereto are reset. The ash tray may include a cigarette lighter (32) which is covered and non-actuatable when the lid is closed but which is exposed and can be actuated when the lid is opened.
