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.
Claims31
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.
A storage unit comprising:
- a housing defining a nozzle portion, an active substance holder, and a charge portion;
- a nozzle in said nozzle portion having an inlet spaced from the active substance holder by a space, said nozzle having an inlet;
- a rupturable closure having an edge attached to the active substance holder and radially extending lines of weakness spaced from said edge;
- an active substance retained in said active substance holder by the rupturable closure element;
- a piston;
- and
- a propellant charge in the charge portion for forcing the piston through the active substance holder to rupture the rupturable closure and expel the active substance through the nozzle;
- said space and said rupturable closure element being configured such that closure element flaps formed when said rupturable element ruptures remain attached to said active substance holder and spaced from said nozzle inlet.
A defensive apparatus having 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, comprising:
- a closure element sealing said storage space,
- a nozzle having at least one nozzle channel and a nozzle entry space situated between the nozzle and the closure element,
- said nozzle entry space having a circumferential inner wall,
- a propellant charge in order to force the filling by means of a piston out of the storage space through the at least one nozzle channel,
- 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 space 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 element opens into said nozzle entry space and said opened closure element being situated near said circumferential inner wall, whereby parts of the opened closure element do no 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.
