Method of making e-vaping section with flow restrictor to provide desired resistance-to-draw (rtd)

Abstract

The method includes first inserting a seal into a first end of a first housing of a first e-vaping section, the first housing at least partially defining at least one inlet, second inserting a flow restrictor into a second end of the seal, the flow restrictor defining a first air passage in communication with the at least one inlet, the flow restrictor being configured to providing a desired resistance-to-draw (RTD) for the first e-vaping section, and first connecting a connector to the first end.

What is claimed is: 
     
         1 . A method, comprising:
 first inserting a seal into a first end of a first housing of a first e-vaping section, the first housing at least partially defining at least one inlet;   second inserting a flow restrictor into a second end of the seal, the flow restrictor defining a first air passage in communication with the at least one inlet, the flow restrictor being configured to providing a desired resistance-to-draw (RTD) for the first e-vaping section; and   first connecting a connector to the first end.   
     
     
         2 . The method of  claim 1 , wherein the first inserting occurs before the second inserting. 
     
     
         3 . The method of  claim 1 , wherein the second inserting inserts the flow restrictor so that the seal encompasses the flow restrictor. 
     
     
         4 . The method of  claim 1 , further comprising:
 defining a reservoir within the first housing, the reservoir being configured to contain a pre-vapor formulation;   configuring a wick to communicate the pre-vapor formulation from the reservoir to a heater; and   arranging the heater to at least partially volatize the pre-vapor formulation to entrain a vapor in a second air passage that is in communication with the first air passage.   
     
     
         5 . The method of  claim 4 , wherein the arranging arranges the heater so that the second air passage is downstream of the first air passage relative to a direction of a normal airflow through the first e-vaping section during an operational use of the first e-vaping section. 
     
     
         6 . The method of  claim 4 , wherein the first connecting connects the connector so that an electrical terminal held within the connector is electrically connected to the heater. 
     
     
         7 . The method of  claim 1 , wherein the second inserting inserts the flow restrictor so that an airflow cross-sectional area of the first passage is less than a combined airflow cross-sectional area of the at least one inlet. 
     
     
         8 . The method of  claim 1 , wherein the second inserting inserts the flow restrictor that is made from a first material that has a different hardness relative to a second material of the seal. 
     
     
         9 . The method of  claim 8 , wherein the first material is at least one of a plastic, a metal or combinations thereof. 
     
     
         10 . The method of  claim 1 , wherein the second inserting inserts the flow restrictor that is made from a first material that is a harder material relative to a second material of the seal, the second material being a resilient material. 
     
     
         11 . The method of  claim 1 , wherein the first inserting inserts the seal so that an outer surface of the seal seals with an interior surface of the first housing. 
     
     
         12 . The method of  claim 1 , wherein the first inserting inserts the seal so that an outer surface of the seal seals with an interior surface of the first housing, the seal being a gasket made of a resilient material. 
     
     
         13 . The method of  claim 4 , further comprising:
 sliding an inner tube into the first housing, the inner tube at least partially defining the second air passage.   
     
     
         14 . The method of  claim 13 , wherein the first inserting inserts the seal so that an outer surface of the seal seals with an interior surface of the first housing and the seal contacts at least a portion of the inner tube, the seal at least partially sealing a third end of the inner tube. 
     
     
         15 . The method of  claim 1 , wherein the first connecting connects the connector to seal the first end, the connector being one of a threaded connector, a snug-fit connector, a snap-fit connector, a detent, a clamp, a clasp, or combinations thereof. 
     
     
         16 . The method of  claim 1 , further comprising:
 second connecting a mouth-end insert to the first e-vaping section to seal a fourth end of the first e-vaping section.   
     
     
         17 . The method of  claim 1 , further comprising:
 third connecting a second e-vaping section to the first end to form an e-vaping device, the second e-vaping section including a power source.   
     
     
         18 . The method of  claim 17 , wherein the third connecting connects the second e-vaping section such that a second housing of the second e-vaping section and the first housing collectively define the at least one inlet. 
     
     
         19 . The method of  claim 17 , wherein the third connecting connects the second e-vaping section so that the power source is operationally connected to a heater to energize the heater during an operational use of the e-vaping device, the heater being in the first e-vaping section. 
     
     
         20 . The method of  claim 17 , wherein the third connecting connects the second e-vaping section so that control circuitry is configured to control a supply of electrical power from the power source to a heater during an operational use of the e-vaping device, the control circuitry being in the second e-vaping section, the heater being in the first e-vaping section.
