Abstract

An eyelash molding device includes an applicator interface including a concave molding surface, a plurality of ribs extending across the concave molding surface, a plurality of vents, wherein a vent is placed between two adjacent ribs, an air propulsion unit that delivers air to the vents, and a heating element that heats the air prior to exiting through the vents.

Claims

exact text as granted — not AI-modified
The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 
     
         1 . An eyelash molding device, comprising:
 an applicator interface including a concave molding surface;   a plurality of ribs extending across the concave molding surface;   a plurality of vents, wherein a vent is placed between two adjacent ribs;   an air propulsion unit that delivers air to the vents; and   a heating element that heats the air prior to exiting the vents.   
     
     
         2 . The eyelash molding device of  claim 1 , comprising:
 an elongated handle having a cylinder shape, wherein the cylinder shape transitions to an oval shape, wherein the oval shape is disposed normal to the cylinder, and the applicator interface is placed within the oval shape.   
     
     
         3 . The eyelash molding device of  claim 1 , wherein the ribs extend across a long dimension of an oval-shaped applicator interface. 
     
     
         4 . The eyelash molding device of  claim 1 , wherein a profile of the rib includes a concave curve. 
     
     
         5 . The eyelash molding device of  claim 1 , further comprising a cartridge within the device, the cartridge including a thermo-reactive formula. 
     
     
         6 . The eyelash molding device of  claim 5 , further comprising a microfluid dispensing unit to dispense the thermo-reactive formula to the applicator interface. 
     
     
         7 . The eyelash molding device of  claim 5 , wherein the cartridge comprises a tag, and the device includes circuitry to read the tag and recognize a temperature parameter for the thermo-reactive formula. 
     
     
         8 . The eyelash molding device of  claim 7 , further comprising a temperature regulation unit that heats air to the temperature parameter that activates the thermo-reactive formula. 
     
     
         7 . The eyelash molding device of  claim 1 , wherein the air propulsion unit delivers cooled air to the vents. 
     
     
         10 . The eyelash molding device of  claim 9 , further comprising circuitry to turn off the heating element after elapse of a pre-programmed amount of time. 
     
     
         8 . The eyelash molding device of  claim 1 , wherein the heating element is a thermoelectric module that heats and cools the air from the air propulsion unit. 
     
     
         9 . The eyelash molding device of  claim 1 , wherein the air propulsion unit comprises an air blower or a compressed air cartridge. 
     
     
         13 . The eyelash molding device of  claim 1 , further comprising a soft pad adjacent to the applicator interface, the soft pad is placed perpendicular to the applicator interface. 
     
     
         14 . A method of curling eyelashes, comprising:
 applying a thermo-reactive formula to eyelashes;   applying heated air to the thermo-reactive formula;   while applying the heated air, pressing the eyelashes against a concave surface; and   automatically turning off heated air after elapse of a pre-programmed amount of time followed by applying non-heated or cooled air to set the thermo-reactive formula.   
     
     
         10 . The method of claim  14 , further comprising applying the thermo-reactive formula with a device and applying heated air with the same device. 
     
     
         11 . The method of claim  15 , wherein the thermo-reactive formula is stored in a cartridge within the device, the method further comprising, with the device, reading a tag on the cartridge, and device controls a heating element to provide a pre-programmed temperature and time for applying the heated air. 
     
     
         12 . The method of claim  16 , further comprising, after elapse of the pre-programmed time, applying non-heated air with the device to the thermo-reactive formula. 
     
     
         13 . The method of claim  15 , further comprising resting the device on the face adjacent to a cheekbone to allow pressing the curved surface on the device against the eyelashes.
