The fluid in around environment control the device in order possibly to discharge. According to the execution form of specification of this invention, this device, fluid division, adjoining to that, as it is arranged, through the orifice, that and the fluid the orifice division which is communicated and, has the housing which it possesses. Fluid division accommodates the fluid in order to discharge to around environment. You remove orifice division and, you include fluid discharge opening which is covered by the possible sealing up element at the same time in not yet operating state of the particular device, accommodate the fluid of the primary quantity. The fluid restrictor is arranged, in the above-mentioned not yet operating state, adjoining to the above-mentioned orifice in order to restrict the flow of the liquid to while orifice dividing from fluid division. The gas evolution cell, when the particular device is in operating state, because the gas which occurs due to the particular cell that tries is led while fluid dividing, has communicated with fluid division selectively. The fluid membrane is arranged with the gas evolution cell and fluid division, in operating state, makes the gas pass which occurs and due to the above-mentioned cell lets flow to fluid division, on the one hand, in not yet operating state, the fluid inside the particular fluid container passing, prevents the fact that it flows to the cell. The particular device, removing the sealing up element, through fluid discharge opening, discharges the fluid of the primary quantity to outside orifice division, at the same time under controlling, the cell operating, generates the gas, from fluid division sends the fluid, to orifice division, operates by discharging from the aforementioned fluid discharge opening.流体を周囲環境中に制御可能に放出するための装置。この発明の特定の実施形態によれば、この装置は、流体区画と、それに隣接して配置されるとともに、オリフィスを介してそれと流体連通するオリフィス区画と、を有するハウジングを具える。流体区画は、周囲環境に放出するための流体を収容する。オリフィス区画は、取り外し可能な密封要素によって覆われる流体排出開口を含み、かつ当該装置の未作動状態では、初期
