A storage unit comprising: a nozzle unit having a nozzle inlet and at least one nozzle channel, a storage space holding a filling selected from the group consisting of a solid active substance, a gaseous active substance, a liquid active substance and a combination of a solid, a gaseous and a liquid active substance, an openable closure element sealing said storage space; a store output comprising the nozzle unit and a nozzle entry space having a circumferential inner wall and being arranged between the nozzle inlet and the closure element; and a propellant charge in order to force the filling by means of a piston out of the storage space through the store output into a free environment, wherein, prior to the firing of the propellant charge, the closure element keeps the filling away from the nozzle entry space and prevents it from emerging from the storage unit in a long term, the nozzle entry space and the closure element being matched with each other such that after the firing of the propellant charge, said closure opens, said opened closure element being situated into said nozzle entry space near said circumferential inner wall; whereby parts of the opened closure element do not enter or pass through the nozzle unit and are not torn off and no parts of the opened closure element partially or entirely close said at least one nozzle channel.
