Problems solved by technology

[0013] Another related problem is that the high precision required for positioning, e.g. in the sub-millimeter range, is too costly in commissioning time to adjust components from different pre-assembled assemblies

Embodiment Construction

[0029] An aerosol nebulizer system 1 comprising a first exemplary embodiment of an aerosol top mechanism 2 according to the present invention is shown in FIG. 1 . As shown in FIG. 1 , a first exemplary embodiment of an aerosol top 2 according to the present invention has a substantially tubular body 103 and a substantially tubular portion 112 extending inwardly and along the body 103 . Pistons 110 are connected. The body 103 includes a lower base portion 1031 extending radially beyond the lower end of the body 103 in a flange-like configuration, which rests against the piston shoulder 1101 when the pump is in the rest position. superior. The flexible housing 40 covers the aerosol top mechanism 2 and the body 103 . The tubular portion of the piston contains a hollow axial internal passage 1041 which communicates fluid to the body 103 through radial passages 114 on either side of the internal passage 1041 when the pump is in the load or "ready" position.

Abstract

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.

Description

technical field [0001] The present invention generally relates to a system and method for producing a spray or aerosol discharge, and more particularly to a system and method for producing a spray or aerosol discharge using a mechanical aerosol top mechanism that is optimally positioned in the discharge The size of the fluid particles is controlled. Background technique [0002] One of the problems encountered in the design of propellant-free mechanical sprayers or aerosol sprayers is how to optimally control and preferably reduce the size of the fluid particles forming the aerosol spray, and how to narrow the size of the particles range, i.e. optimize particle size uniformity. It is known in the prior art that a loss of mechanical energy, also referred to as "head loss", occurs in the fluid conduit or channel of an aerosol when releasing an aerosol spray to form larger sized fluid particles. Loss is a major contributing factor. Such head losses can be caused by, for exam...
