DETAILED DESCRIPTION

[0091] The following disclosure is directed to various embodiments, including those depicted in FIGS. 1-15 appended hereto. As depicted in FIG. 1, the pressurized sublingual delivery device eliminates the use of a power source or battery, which are commonly employed in prior art devices and have been known to explode without warning and cause serious injuries including burns, blindness or in extreme cases, death.

[0092] Embodiments described herein relate to an encapsulated, pressurized, sublingual aerosol nano mist vapor delivery device that delivers a precise dose of micellized liquid nicotine formula. According to embodiments, the precise or controlled dose is achieved with each depression of an actuator, which preferably is positioned on top of a metered valve crimped to a pressurized aluminum canister. The aluminum canister may be Fluorinated Ethylene Propylene (FEP) coated, so as to avoid any undesired chemical interaction between the micellized liquid formula and the aluminum canister.

[0093] In embodiments, the micellized liquid formula may be comprised of at least one of a micellized liquid nicotine, micellized liquid cannabidiol, micellized liquid tetrahydrocannabinol, and a micellized nicotine salt.

[0094] The encapsulated pressurized sublingual aerosol nano mist vapor delivery device is created by placing an aluminum canister, containing a micellized liquid nicotine formula having a bag-on-valve system or pharmaceutical grade liquid propellant residing inside and crimped metered valve attached with actuator positioned on top, into the protective plastic canister receptacle housing with a protective child resistant protective plastic cap secured on top.

[0095] The encapsulated pressurized sublingual delivery device preferably comprises a metered valve crimped onto the aluminum canister, such as by use of a metal collette, which crimps the metered valve mounting cup of the aluminum metered valve against the rim of the aluminum canister. The crimp securely holds the metered valve onto the aluminum canister which once gassed maintains approximately 70 pounds per square inch (psi) pressure in the aluminum canister.

[0096] The actuator, preferably made from high quality plastic resins, has a discharge nozzle that may be altered to expel various nano mist or micron-sized vapor particles while delivering a precise volume of micellized liquid nicotine formula to the sublingual membrane area once depressed. The volume of micellized formulation delivered with each activation of the actuator is preferably within the range of 50 to 100 microliters. In one embodiment, the volume is precisely controlled at 100 microliters by utilizing a metered valve configured to release 100 microliters. In another embodiment, the volume is precisely controlled at 65 microliters.

[0097] According to one particular aspect, the method of delivering a known volume of micellized liquid nicotine formula is as follows: once the valve stem has been fully depressed, a valve stem side piercing passes through a diaphragm. The volume of micellized liquid nicotine formula enters into the metering chamber, which includes a precise, controlled volume of micellized liquid nicotine formula and propellant based on the configuration of metered valve. From the first actuation until the last actuation, the pressure in the canister remains constant allowing a controlled, consistent and precise dose of micellized liquid formula and propellant to be expelled through the actuator's discharge nozzle.

[0098] Referring now in detail to FIG. 1, various components of the pressurized, encapsulated, sublingual delivery device 100 are illustrated. According to a preferred embodiment, the delivery device 100 comprises an aluminum canister 132 having a generally concave base bottom 142 positioned securely inside protective plastic canister receptacle housing 144 with a protective plastic canister receptacle child resistant cap 154. The child resistant cap 154 may be attached by pushing plastic ribs 158 into the plastic base receptacle channels 148. Mounting cup 110 of metered valve 102 is crimped over aluminum canister lip 134, aluminum canister throat 136 and against aluminum canister rim 138 of aluminum canister 132, thereby allowing a pressurized liquid propellant such as, 1,3,3,3-Tetrafluropropene, HFO 1234ze, Norflurane, HFA 134a or similar pharmaceutical grade propellant 160 to be introduced under pressure into aluminum canister 132.

[0099] The volume of liquid propellant 160 is pre-determined by the volume of micellized liquid nicotine formula 162 introduced into the aluminum canister 132. It is known by those skilled in the art that pressurized liquid such as 1,3,3,3-Tetrafluropropene, HFO 1234ze, Norflurane, HFA 134a or similar pharmaceutical grade propellant 160 introduced into aluminum canister 132 containing a micellized liquid nicotine formula 162 will expand as outside temperatures increase. The pre-determined volume of liquid propellant 160 and micellized liquid nicotine formula 162 introduced into canister 132 are adjusted to allow expansion when temperatures and pressure increase inside aluminum canister 132.

[0100] In a preferred embodiment, the starting pressure of the prefilled aluminum canister 132 is approximately 70 psi, (pounds per square inch), at an outside temperature of approximately 72 degrees Fahrenheit or 22.2 Celsius. Once micellized liquid nicotine formula 162 and liquid propellant 160 are introduced into aluminum canister 132, air pocket 164 is required to allow expansion inside aluminum canister 132 once outside temperatures increase beyond 72 degrees Fahrenheit or 22.2 Celsius. Actuator 118, which preferably resides over metered valve sleeve 124 via the actuator base receptor 122 is activated by depressing actuator ridged finger control 128. A micellized liquid formula 162 and liquid propellant 160 under pressure are drawn up through valve dip tube 116 and forced through actuator discharge channel 126 and out actuator discharge nozzle 120 with a uniform nano mist pattern created from actuator discharge area 130.

[0101] It has been discovered that micellized liquid nicotine formula 162 when combined with liquid propellant Norflurane, HFA 134a remains miscible forming a homogeneous mixture without separation between combined liquid propellant 160 and micellized liquid nicotine formula 162. This discovery simplifies the use of the encapsulated sublingual aerosol nano mist vapor delivery device 100 as it is not required to be shaken to mix the liquid propellant 160 and micellized liquid nicotine formula 162 together prior to use. Without micellization pure nicotine would remain in suspension and could cause health issues to the user. When liquid propellant 160 and micellized liquid formula 162 are introduced into a clear glass vial, having metered valve 102 attached, both liquid solutions remain miscible, visibly clear, with a viscosity similar to that of water. This revelation and discovery will challenge all combustible tobacco products as it allows for a safer, easy to use, quicker uptake with increased bioavailability into the sublingual mucosa while decreasing nicotine levels up to eighty percent (80%).

[0102] FIG. 2 is a cross sectional view of metered valve 102 comprised of metered valve stem 104, metered valve internal gasket 106, metered valve external gasket 108, metered valve mounting cup 110, metered valve spring 112, metered valve metering chamber 114, and metered valve dip tube 116. Once micellized liquid nicotine formula 162 (not shown) and liquid propellant 160 (not shown) are introduced into aluminum canister 132, a combined pressurized homogeneous water-soluble liquid solution is created and forced into metered valve dip tube 116 and metering chamber 114. Once actuator 118 (not shown) is depressed metered valve stem 104 is pushed downward past metered valve internal gasket 106 and metered valve external gasket 108 overcoming resistance from metered valve spring 112 allowing micellized liquid formula 162 (not shown) and liquid propellant 160 (not shown) to be expelled through actuator discharge nozzle 120 (not shown).

[0103] FIG. 3 is a cross-sectional side view of actuator 118, having an actuator base receptor 122 securely placed over metered valve stem 104 (not shown) via actuator valve sleeve 124. Once actuator 118 is depressed by pushing downward on actuator ridged finger control 128, micellized liquid nicotine formula 162 (not shown) and liquid propellant 160 (not shown) under pressure are forced through actuator discharge channel 126 and actuator discharge nozzle 120 creating a micellized nicotine nano mist vapor spray pattern from actuator discharge area 130. Discharge nozzle 120 can be altered in diameter to provide various nano mist, vapor micron particle sizes.

[0104] FIG. 4 is a perspective view of actuator 118 showing actuator ridged finger control 128 which is concave and ridged to accommodate finger location and correct direction of micellized nicotine nano mist spray. The actuator discharge area 130 is circular allowing a micellized nicotine nano mist spray to be expelled uniformly from the actuator discharge nozzle 120.

[0105] FIG. 5 is a cross-sectional view of aluminum canister 132, having an aluminum canister concave base bottom 142 and aluminum canister base 140 where metered valve 122 (not shown) resides over aluminum canister lip 134 and aluminum canister throat 136. When metered valve 122 (not shown) is crimped to aluminum canister 132, metered valve mounting cup 110 (not shown) is crimped firmly against aluminum canister rim 138 allowing a secure fit and safe pressure to remain in aluminum canister 132.
