Embodiment Construction

[0034] figure 1 Shown are a base element 1 , a cover element 2 , a sealing ring 3 with an inner diameter 4 and a nozzle insert 5 . The bottom element 1 , the cover element 2 and the nozzle insert 5 can be designed as injection-molded parts. In the injection molding process, special synthetic materials are allowed to achieve the desired shape cost-effectively.

[0035] The size of the nozzle insert 5, in particular the nozzle opening 6, can have a particularly large influence on the size of the spray particles or droplets, so that it is basically conceivable that other manufacturing processes and / or materials can be kept more robust for the nozzle insert 5. Small manufacturing tolerances. Due to the simple geometry of the nozzle insert 5 , the production process for replacing the nozzle insert 5 does not involve any higher costs.

[0036] figure 2Shown are a cover element 7 , a sealing ring 8 and a base element 9 in which a nozzle insert 10 is embedded. The nozzle insert ...

Abstract

The invention concerns a replacement cartridge for producing an aerosol, having at least one base element (1) and at least one cover element (2), a reservoir for a first, in particular, liquid, aerosol component being formed in the base element and / or the cover element, an atomizing nozzle (5, 6) being formed in the replacement cartridge, and the base element and cover element being connected to one another by means of a bayonet closure.

Description

technical field [0001] The invention relates to an exchangeable cartridge for producing a spray, which has at least one bottom element and at least one cover element, wherein a first, in particular liquid, spray is formed in the bottom element and / or the cover element Containers for ingredients. Background technique [0002] The above-mentioned replaceable cartridges are used in nebulizers, inhalers or chambers (Kabinen) to shield the respiratory tract or body of an organism from the spray. This can not only achieve the purpose of treatment, but also achieve the purpose of disinfection. [0003] In WO 2011 / 082838 a replaceable cartridge for generating a spray is described, consisting of at least two parts which can be connected to each other after being filled with the liquid to be atomized. This can be achieved, for example, by a plug connection or a screw connection. [0004] For screwing, the components must be precisely aligned with each other and be rotatable relativ...
