Aspects and many of the attendant advantages of the claimed subject matter will become more readily appreciated as the same become better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings.

The detailed description set forth below in connection with the appended drawings, where like numerals reference like elements, is intended as a description of various embodiments of the disclosed subject matter and is not intended to represent the only embodiments.

DETAILED DESCRIPTION

Described herein are systems and methods for delivery of formulations in aerosol form onto skin. Certain conventional nebulizers couple with a cartridge containing a formulation for application onto skin. It would be advantageous to be able to use sequentially many cartridges containing various formulations with a single nebulizing body. However, many conventional nebulizers do not adjust the operation of nebulizing components according to specific characteristics of a formulation disposed in a cartridge coupled thereto, such as formulation viscosity. Accordingly, during operation such conventional nebulizers may fail to convert all or some of the formulation from a liquid to a mist of fine droplets, for example, because they provide insufficient power to the nebulizing components. Further, many conventional nebulizers couple with cartridges containing formulations for application onto the skin in a way that permanently opens the cartridge. In this regard, formulation remaining in the cartridge may leak from one or more portions of the cartridge when the cartridge is uncoupled from the nebulizer. Accordingly, a user cannot replace a first cartridge that is not completely empty with another cartridge without remaining formulation leaking from the first cartridge. Additionally, any such remaining formulation maybe altered by, for example, exposure to air due to permanently opening the cartridge, thus rendering it unsuitable for future use.

To that end, the following discussion provides examples of systems including a nebulizing body including at least one electro-mechanical nebulizing element; and a replaceable cartridge including one or more fluid reservoirs; and a valve in fluid communication with the one or more fluid reservoirs, wherein the nebulizing body is configured to releaseably receive the replaceable cartridge. As will be described in more detail below, in an embodiment the valve is in a closed state when the replaceable cartridge is not received by and engaged with the nebulizing body. In that regard, a formulation disposed with the fluid reservoir will not leak or otherwise leave the fluid reservoir when the replaceable cartridge is not received by and engaged with the nebulizing body. Additionally, as discussed further herein, in an embodiment, the systems described herein include discharge aerosol circuitry operably coupled to the at least one electro-mechanical nebulizing element and configured to generate a discharge aerosol responsive to one or more inputs indicative of a replaceable cartridge identification. In this regard, in an embodiment the systems described herein are configured to operate the electro-mechanical nebulizing element according to a formulation disposed within the fluid reservoir to discharge an aerosol therefrom.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments of the present disclosure. It will be apparent to one skilled in the art, however, that many embodiments of the present disclosure may be practiced without some or all of the specific details. In some instances, well-known process steps have not been described in detail in order not to unnecessarily obscure various aspects of the present disclosure. Further, it will be appreciated that embodiments of the present disclosure may employ any combination of features described herein. FIGURE 1 A is a front view of a system 100 in accordance with an embodiment of the disclosure. FIGURE 1B is a top plan view of the system 100 of FIGURE 1A. FIGURE 1C is a partially-exploded perspective view of the system 100 of FIGURE 1A. FIGURE 1D is a cross-sectional view of the system 100 of FIGURE 1A taken along lines 1D-1D in FIGURE 1A. As shown in FIGURES 1A-1D, an embodiment of system 100 includes a nebulizing body 120 including a nebulizing assembly 122. The system 100 further includes a replaceable cartridge 110 including a fluid reservoir 114 and a valve 112 in fluid communication with the fluid reservoir 114. FIGURE 1C is a partially- exploded view of the system 100 illustrating one embodiment of the replaceable cartridge 110 uncoupled from nebulizing body 120.

As illustrated in FIGURES 1A, 1B, 1D, and 1E, the replaceable cartridge 110 is releaseably received by the nebulizing body 120. As used herein, the replaceable cartridge 110 is releaseably received by the nebulizing body when the replaceable cartridge 110 is securely but removably coupled to the nebulizing body 120. In this regard and as discussed further herein, the replaceable cartridge 110 is releaseably received by the nebulizing body 120 such that the replaceable cartridge 110 can be securely coupled to and subsequently released by the nebulizing body 120 one or more times. In an embodiment, the replaceable cartridge 110 includes one or more detents 117 and the nebulizing body 120 includes detent-receiving structures, or vice versa, both of which are configured to cooperatively and removeably couple the replaceable cartridge 110 and the nebulizing body 120. Of course, the system 100 can include other cooperatively-coupling structures, such as threads configured to removeably couple the replaceable cartridge 110 and the nebulizing body 120.

In an embodiment, the nebulizing body 120 is configured to releaseably receive the replaceable cartridge 110 without engaging with the releasable cartridge 100, thus leaving the valve 112 in a closed state, as illustrated in FIGURE 1D. As used herein, the replaceable cartridge 110 is engaged with the nebulizing body 120 when the valve 112 is in an open state and the fluid reservoir 114 of the replaceable cartridge 110 is in fluid communication with the nebulizing assembly 122. Accordingly, the valve 112 is in a closed state when the replaceable cartridge 110 is not engaged with the nebulizing body 120. Thus, when the replaceable cartridge 110 is not engaged with the nebulizing body 120, the fluid reservoir 114 is not coupled in fluid communication with the nebulizing assembly 122. In this regard, the replaceable cartridge 110 in an unengaged configuration is received by the nebulizing body 120 and, accordingly, the valve 112 is in a closed state, as illustrated FIGURES 1D and 1E.

Alternatively, the valve 112 is in an open state and the fluid reservoir 114 is coupled in fluid communication with the at least one nebulizing assembly 122 when the replaceable cartridge 110 is received by and engaged with the nebulizing body 120. In this regard, attention is directed to FIGURES 2A, 2B, and 2C, in which a configuration of the system 100 according to embodiments of the disclosure is illustrated. Referring to FIGURE 2B and 2C, the replaceable cartridge 110 is shown releaseably received by the nebulizing body 120 by detents 117. In order to be engaged, the nebulizing body 120 in some embodiments includes an actuatable switch 128 configured to selectively place the valve 112 in an open state.

For example, as illustrated in FIGURES 1D, 1E, 2B, and 2C, the nebulizing body 120 includes a switch 128 operatively coupled to a cam 126, which is, in turn, operatively coupled to a push rod 124. In this embodiment, the cam 126 pivots about pivot 130 against a biasing force of a spring 180. In an embodiment, the spring 180 biases the cam 126 into a first position in which the valve 112 in a closed position, as illustrated in FIGURES 1D and 1E. In use, as the switch 128 is selectively actuated via movement (e.g., linear movement, etc.), such as by the hand of a user, from the first position, as illustrated in FIGURE 1D and 1E, to a second position, as illustrated in FIGURES 2B and 2C, the cam 126 is rotated (in the direction of the arrow) against the biasing force of the spring 180. Rotation of the cam 126 causes the push rod 124 to be moved (e.g., linearly, etc.) to place the valve 112 in an open state. In this regard, the valve 112 is placed in an open state and the fluid reservoir 114 is coupled in fluid communication with the nebulizing assembly 122 when the switch 128 is activated, such as by the hand of a user. Removal of the hand of the user from the switch 128 allows the biasing force of the spring 180 to return the cam 126 and the switch 128 the non-engaged position (e.g., unactuated position, etc.) as shown in FIGURES 1D and 1E

In an embodiment, when the switch 128 is activated the valve 112 is placed in an open state and the discharge aerosol circuitry (discussed further herein with respect to FIGURE 5), which is operably coupled to the nebulizing assembly 122, is activated, thereby causing an aerosol A to be discharged from the system 100, as illustrated in FIGURES 2A, 2B, and 2C. As illustrated in FIGURE 2C, in an embodiment, when the valve 112 in an open state, fluid in the fluid reservoir 114 is allowed to flow past valve seal 159 and into a space 132 that is disposed in fluid contact with the nebulizing assembly 122. In this regard, an aerosol A is discharged by the system 100 when the valve 112 is in an open state. This is in contrast to the embodiment illustrated in FIGURE 1D, in which the valve seal 159 is shown disposed against the valve seat 163, thereby placing the valve 112 in a closed state. In an embodiment, element 161 forms part of a valve seal. In an embodiment, element 161 forms part of a valve stop.

In an embodiment, the system 100 includes an input assembly, such as input assembly 162 (see FIGURE 5) in addition to switch 128. As discussed further herein with respect to FIGURE 5, in an embodiment, the discharge aerosol circuitry is triggered (e.g., receive an input, electronically actuated, energized, etc.) to activate the nebulizing assembly 122 from the input assembly, thereby discharging aerosol A from system 100. In this regard, the fluid reservoir 114 is placed in fluid communication with the nebulizing assembly 122 through activation of the switch 128 and the nebulizing assembly 122 is activated in response to activation of the input assembly.

Referring to FIGURES 3 A and 3B, the replaceable cartridge 110 including valve 112 is illustrated separately from the nebulizing body 120. The replaceable cartridge 110 is illustrated to include cartridge body 111 and a cartridge top 118, which, when coupled, define in part the fluid reservoir 114. In the illustrated embodiment, the valve 112 includes stop 161 coupled to shaft 156 and configured to limit the movement of shaft 156. In the illustrated embodiment, valve 112 also includes guide 158 slideably disposed around a portion of shaft 156 and configured to guide the movement of shaft 156 as it travels in opening and closing the valve 112. In FIGURES 3 A and 3B, the replaceable cartridge 110 is shown to include protective seal 150, such a paper or plastic protective seal, configured to be removed by a user prior to use or punctured by coupling the removable cartridge 110 to the nebulizing body 120.

In operation, when the replaceable cartridge 110 is received by the nebulizing body 120 and, for example, the switch 128 has been activated (e.g., moved linearly, displaced, engaged, etc.), the push rod 124 displaces a valve seal 159 from the valve seat 163, thereby placing the valve 112 in an open state, as illustrated in FIGURE 2C. Referring to FIGURE 3 A, the valve 112 is shown to include an annular ring 154 configured to cooperatively engage with nebulizing body 120 to provide a fluid-tight seal between the replaceable cartridge 110 and space 132 disposed within nebulizing body 120 (See FIGURE 2C). In this regard, the valve 112 is configured to direct any fluid in the fluid reservoir 114 to the nebulizing assembly 122. Further, when the replaceable cartridge 110 is engaged with and received by the nebulizing body 120 and, accordingly, the valve 112 is an open state, fluid from the replaceable cartridge 110 is prevented from entering other portions of the nebulizing body 120.

It will be appreciated that valve 112 can be any valve configured to selectively place fluid reservoir 114 in fluid communication with nebulizing assembly 122 when the replaceable cartridge 110 is received by and engaged with the nebulizing body 120. In an embodiment, the valve 112 operates as a one-way valve, such as a check valve. In an embodiment, the check valve can be of the ball type, the diaphragm type, or of the swing type. In an embodiment, valve 112 is a two-way valve.

In an embodiment, the replaceable cartridge 110 includes a fluid disposed in the fluid reservoir 114. In an embodiment, the replaceable cartridge 110 includes a cosmetic or dermatological formulation disposed in the fluid reservoir 114. In an embodiment, the cosmetic or dermatological formulation includes a composition chosen from a foundation, a perfume, a moisturizer, a self-tanning agent, a lotion for the body or the face, a composition containing a hair agent, a sunscreen composition, and combinations thereof, among others.

In an embodiment, the system 100 includes two or more replaceable cartridges 110 each configured to be received by and engage with the nebulizing body 120. In an embodiment, each of the two or more replaceable cartridges 110 includes an identifier 116 configured to emit an input for receipt by cartridge identification circuitry (See FIGURE 5). The input is indicative of the formulation disposed in the respective fluid reservoirs 114.

Referring to FIGURE 4, a nebulizing assembly 122 formed in accordance with an exemplary embodiment of the present disclosure and configured for use with system 100 will now be described in detail. As noted above, the nebulizing assembly 122 is configured to produce on-demand aerosol. The terms "nebulize," "nebulizing," etc., should be construed to include atomizing, misting, generating an aerosol, reducing to fine particles or spray, etc.

As shown in FIGURE 4, the nebulizing assembly 122 generally includes at least one electro-mechanical nebulizing element 123, such as a piezoelectric element, fluidically coupled to the fluid reservoir 114 (FIGURE 1D) when the valve 112 is in an open state and configured to discharge an aerosol (See FIGURES 2A-2C). In an embodiment, the nebulizing assembly 122 includes a mesh 125, such as a metallic mesh, disposed adjacent to the electro-mechanical nebulizing element 123, which receives a fluid from the fluid reservoir 114 of the replaceable cartridge 112. In the illustrated embodiment, the electro-mechanical nebulizing element 123 concentrically surrounds the mesh 125. In an embodiment, the nebulizing assembly 122 is a vibrating mesh dispenser assembly including a mesh 125 including apertures that is concentrically surrounded by the electro-mechanical nebulizing element 123. In an embodiment, the nebulizing assembly 122 is configured to discharge an aerosol including particles having an average diameter of less than 100 nm.

In an embodiment, the nebulizing assembly 122 is received within the replaceable cartridge 110. In an embodiment, the nebulizing assembly 122 is received within the nebulizing body 120. In an embodiment, the nebulizing assembly 122 includes replaceable nebulizing elements 123.

In an embodiment, during use, the electro-mechanical nebulizing element 123 contracts and expands upon the application of an alternating electric current, and consequently, the electro-mechanical nebulizing element 123 vibrates. When a liquid, such as a formulation from the fluid reservoir 114 of the replaceable cartridge 110, is in contact with the vibrating mesh 125, pressure builds in the vicinity of the mesh 125, creating a pumping action that extrudes the formulation through the apertures. When the mesh 125 vibrates at a sufficient frequency and with sufficient power, an aerosol A is formed from the formulation, which is emitted from the system 100 through mesh 125.

In an embodiment, the system 100 includes suitable circuitry for identifying one or more replaceable cartridges 110 received by the nebulizing body 120 and suitable circuitry for sending at least one output signal indicative of the identified replaceable cartridge(s) 110 for controlling and/or activating the nebulizing assembly 122. In that regard, attention is directed back to FIGURE 2B, where a system 100 including circuitry for identifying one or more replaceable cartridges in accordance with embodiments of the present disclosure is illustrated. In the illustrated embodiment, replaceable cartridge 110 includes an identifier 116. The nebulizing body 120 includes cartridge identification assembly 172 (not shown in FIGURE 2B). As discussed further herein with respect to FIGURE 5, in certain embodiments the identifier 116 includes circuitry configured to generate one or more inputs for receipt by the cartridge identification circuitry disposed within the cartridge identification assembly 172. An embodiment of the internal operating structure of the system 100 and its associated internal assemblies is shown in block diagrammatic form in FIGURE 5. An exemplary operating structure of the system 100 includes a programmed microcontroller or processor 160 configured to control the delivery of power to the nebulizing assembly 122 from the power storage source 164. Further, the processor 160 is configured to operate in accordance with program instructions stored in memory 166 or otherwise stored in hardware format for controlling aspects of the nebulizing assembly 122.

In the embodiment shown, the nebulizing assembly 122 includes discharge aerosol circuitry 178 operably coupled to the electro-mechanical nebulizing element 123 and configured to activate the electro-mechanical nebulizing element 123 to generate a discharge aerosol A (See FIGURES 2A-2C). In one embodiment, the electro-mechanical nebulizing element 123 includes a piezoelectric element that defines part of the nebulizing assembly 122. The discharge aerosol circuitry 178 is configured to activate the nebulizing assembly 122 in response to inputs received from the processor 160, inputs received from one or more modules stored in the memory 166, such as the nebulizing assembly module 168 and the cartridge identification assembly module 170, and/or inputs received from other assemblies (such as the input assembly 162 and the identifier 116). In an embodiment the nebulizing assembly module 168 and the cartridge identification assembly module 170 includes any suitable programs, files, or instructions for activating and controlling the nebulizing assemblyl22.

The discharge aerosol circuitry 178 can be configured to receive input from an input assembly 162 (which may include an on/off button, a power adjust button, a mode control button, a nebulizing button, etc.).

In an embodiment, the system 100 includes discharge aerosol circuitry 178 operably coupled to the nebulizing assembly 122 and configured to generate a discharge aerosol A responsive to one or more inputs indicative of a replaceable cartridge 110 identification. In this regard, in an embodiment, the system 100 includes a cartridge identification assembly 172 including cartridge identification circuitry 174, operably coupled to the discharge aerosol circuitry 178. In this regard, the cartridge identification assembly 172 is configured to receive one or more inputs from an identifier 116 carried by the replaceable cartridge 110 and to generate the one or more inputs indicative of a replaceable cartridge 110 identification for receipt by the cartridge identification circuitry 174.

In an embodiment, the one or more inputs indicative of a replaceable cartridge 110 identification correspond to a fluid disposed in the fluid reservoir 114, and wherein the discharge aerosol circuitry 178 is configured to operate the nebulizing assembly 122 based on the fluid disposed in the fluid reservoir 114. In this regard, in an embodiment, the system 100 is configured to operate the nebulizing assembly 122 based on, for example, a viscosity of a formulation disposed in the fluid reservoir 114. For example, an embodiment, the nebulizing assembly module 168 includes instructions configured to control the delivery of power to the nebulizing assembly 122 from the power storage source 164 controlling an oscillation frequency and an oscillation amplitude of the electro-mechanical nebulizing element 123 tailored to the viscosity of the particular fluid in the fluid reservoir 114. In this regard, sufficient power is provided to the nebulizing assembly 122 to nebulize the formulation and emit an aerosol A from the system 100.

In an embodiment, the cartridge identification assembly 172 is operatively coupled to the replaceable cartridge 110 by one or more of a wired connection or a wireless connection.
