AI Technical Summary

Problems solved by technology

This reduction in pressure results in an observable increase in the size of the aerosol droplets produced and thus a reduction in the quality of the spray produced
[0007] The problem of providing high quality spray at low pressures is further exacerbated if the fluids involved are of high viscosity, as it becomes more difficult to atomize the fluid into sufficiently small droplets

Embodiment Construction

[0035] To assist the reader, a number of terms used throughout this specification will now be defined.

[0036] The term "expansion chamber" is used herein to denote an inner chamber forming part of a fluid flow channel, which is generally (but not necessarily) circular in cross-section, into which fluid flowing through the channel enters through an inlet hole and Leaving through the outlet hole, both the inlet and outlet holes have a cross-sectional area smaller than the largest cross-sectional area of ​​the chamber between them.

[0037] The term "shaped" with respect to an expansion chamber is used herein to indicate that the chamber consists of more than one simple cylindrical cavity and may include tapered or constricted sections as well as sections of non-circular cross-section.

[0038] The term "vortex chamber" is used herein to denote an internal chamber forming part of a fluid flow channel which is configured to impart a rotational and / or swirling motion to a fluid f...

Abstract

An atomising nozzle (10) has an inlet (16), an outlet orifice (21) and an internal fluid flow passageway (20) which connects the inlet (16) to the outlet orifice (21). The nozzle (10) has a body with two component parts (12A,12B) each component part having an abutment surface (22,24) which contacts a corresponding abutment surface on the other of the parts. At least one of the abutment surfaces has at least one groove and / or recess (26a-34a;26b-34b) therein to define part of the fluid flow passageway (20), including an expansion chamber (28). The body has a fixed partition means (44) which extends into the expansion chamber (28) to define one or more than one constricted openings (48) through which fluid is constrained to flow. The constricted opening has a cross sectional area larger than that of the final outlet orifice (21) and is positioned outwardly of an axially central region (52) of the expansion chamber (28) so that the partition means (44) blocks the flow of fluid through said axially central region. At least one of the constricted opening(s) (48) is non-circular when viewed in lateral cross-sect ion.

Description

technical field [0001] The present invention relates to atomizing nozzles. In particular, but not exclusively, the invention relates to an atomizing nozzle for an aerosol can and an aerosol can comprising such an atomizing nozzle. Background technique [0002] Nozzles are commonly used to provide a means of producing sprays of various fluids. In particular, nozzles are often fitted to the outlet valve of a pressurized filled fluid container (such as a so-called "aerosol can") to provide a means by which the fluid stored in the container can be delivered as a spray or aerosol Forms are assigned. A wide range of goods are presented to consumers in this format including, for example, antiperspirant sprays, deodorant sprays, perfumes, air fresheners, disinfectants, paints, insecticides, polishes, hair care products, medicaments, water and lubricants . Additionally, pump or trigger actuated nozzle devices, i.e. release of fluid from a non-pressurized container actuated by the...
