Abstract
A storage unit includes a nozzle unit, a storage space holding an active substance, an openable closure element sealing the storage space, a store output that includes the nozzle unit and a nozzle entry space having a circumferential inner wall arranged between a nozzle inlet and the closure element and a propellant charge and a firing charge for firing the propellant charge in order to force the active substance out of the storage space through the store output into a free environment, where the closure element is configured to remain attached to the storage unit and not interfere with the discharge of the active substance.
Claims12
A replaceable filling tank for a defensive apparatus,
- said filling tank having a sleeve, which holds a liquid active defensive substance usable against a personal aggressor,
- said sleeve having a storage space filled with the active defensive substance and, a fireable propellant charge to force out the filling,
- said storage space having a storage space end area;
- a closure element at the storage space end area, and a piston;
- the storage space being closed in a sealed manner toward the propellant charge by said piston;
- said filling tank having a rest and a limit position for said piston, the limit position being in the storage space end area;
- said piston being driveable towards the closure element from said rest position to said limit position by a propellant gas from the fired propellant charge to force out the active defensive substance by firing the propellant charge,
- said closure element being designed to be opened by a build up of pressure during firing of the propellant charge in an analogous manner to a bursting disk and being designed to be held or positioned firmly after being opened.
