Summary: | A device (1) for spraying a powdery chemical agent is provided with: a container body (11) in which water (51) is to be put; a cylindrical body (23) which is set so as to penetrate a cap (21) that covers a top opening (13) and both ends of which are present respectively in the inside and outside of the container body (11); one pair of sealing films (25,27) which seal respectively both ends of the cylindrical body (23) that is loaded with a powdery chemical agent (30) and which can be broken by the action of a pressure equal to or higher than a prescribed level; and sodium bicarbonate (41) and citric acid (43) which react with the water (51) present in the container body (11) to generate a reaction gas.
La présente invention concerne un dispositif (1) destiné à pulvériser un agent chimique pulvérulent et comprenant un corps de récipient (11) dans lequel de l'eau (51) doit être introduite ; un corps cylindrique (23) traversant le bouchon (21) recouvrant l'ouverture supérieure (13) du corps du récipient et dont les deux extrémités se situent respectivement à l'intérieur et à l'extérieur du corps du récipient (11) ; une paire de pellicules de scellement (25, 27) qui ferment respectivement chacune des deux extrémités du corps cylindrique (23) rempli d'un agent chimique pulvérulent (30) et qui peuvent être rompues sous l'action d'une pression supérieure ou égale à un niveau déterminé ; et du bicarbonate de soude (41) et de l'acide citrique (43) qui réagissent avec l'eau (51) présente dans le corps du récipient (11) afin de générer un gaz réactionnel. |
