an aerosol tip mechanism for an aerosol - type dispenser for dispensing liquid content has a flexible outer shell , a rigid cap portion composed of lower and upper portions , and a rigid nozzle portion having a rigid shaft received within the outlet portion of the flexible outer shell . the rigid shaft interfaces the outlet portion of the outer shell , forming a first normally - closed one - way valve . the lower and upper portions of the rigid cap portion form boots adapted to receive an outlet portion of the flexible outer shell , the boots thereby constraining a lateral motion of the outlet portion of the outer shell , and symmetrically centering the outlet portion around the rigid shaft of the nozzle . the rigid nozzle portion includes a plurality of liquid channels for delivering liquid from a reservoir to a swirling chamber defined within the rigid cap portion , which liquid channels are configured to minimize energy losses of the liquid and promote a more homogeneous fluid particle size in the dispensed aerosol . the aerosol tip mechanism provides for long - term sterility of the stored fluid , which in turn allows for preservation of the sterility of non - chemically preserved formulations , which may be in the form of suspension or liquid gels .
