Vaping cartridge

Abstract

A cartridge for a vaping device can include a tank body forming a reservoir for holding a liquid to be vaporized. A center post has a distal atomizer portion and a proximal vapor outlet portion, the distal atomizer portion for housing a heating element. The center post is formed at least partially of a ceramic material, and the lumen of the proximal vapor outlet portion has an inner diameter of at least 2.7 mm to reduce clogging of the lumen by oil.
