Embodiment Construction

[0031] The present invention relates to a handheld sonic nebulizer that is more economical than conventional sonic nebulizers because the relatively expensive sonic generator and horn head are isolated from the unit dose of liquid dispensed by the nebulizer. Thus, the nebulizing device can be replenished with liquid without liquid accumulating on the horned head.

[0032] exist Figure 1 to Figure 4 In one form of the device shown in , a handheld nebulizing device 100 includes a housing 200 housing an acoustic wave generator 300 and a power and control system 400 . The handheld nebulizer device 100 may be used with a series of unit dose capsules 500 .

[0033] Such as figure 1 As shown in , housing 200 includes an elongated (generally cylindrical) outer sleeve 202 having a rear end 204 and a front end 206 . Outer sleeve 202 has a generally uniform cross-section extending from rear end 204 towards transducer 302 housing front end 206 of power and control system 400 and acous...

Abstract

A unit dose capsule for use with a sonic generator includes a deformable membrane adapted to releasably engage the distal end of the elongate horn, a nozzle including at least one delivery opening; anozzle including at least one delivery opening; and a reservoir containing a liquid composition disposed therebetween. When the unit dose capsule is engaged to the distal end of the elongate horn, thenozzle is disposed in an outwardly facing orientation, and the reservoir is in liquid communication with the at least one nozzle. The unit dose capsule can be included in a kit with a handheld misting device comprising a housing having a dispensing window arranged and configured to contain a sonic generator and a power source.

Description

technical field [0001] The present invention relates to a sterile unit dose nebulizing device utilizing a permanent ultrasonic generator and a replaceable liquid reservoir and nozzle. Background technique [0002] Spray and / or atomizing devices are commonly used to deliver cosmetic and general health care liquids. Low cost systems employ burettes and / or squeeze bottles that have some form of nozzle through which the liquid is forced to deliver relatively uncontrolled doses and droplet sizes. [0003] Expensive systems may employ metering pumps and / or expensive aerosol-forming components. For example, US7992800 to Hseih et al. and US Published Patent Application No. 20120318260 to Hseih et al. disclose nebulizers driven by piezoelectric and / or magnetic drivers to generate an aerosol mist. [0004] Other examples include Technology Partners PLC, EP615470B1; Hailes et al., US7550897; and Brown et al., US77976135, which disclose a liquid projection device employing a transduce...
