An e-vapor device may include a pre-vapor sector and a heater structure arranged in thermal contact with the pre-vapor sector. The pre-vapor sector is configured to hold and dispense a pre-vapor formulation. The heater structure includes a base wire and a shell layer coating the base wire. The base wire is insulated from the shell layer. The shell layer includes at least one recessed portion between a first unrecessed portion and a second unrecessed portion. The at least one recessed portion is a thinner section of the shell layer that is configured to vaporize the pre-vapor formulation to generate a vapor. As a result of the heater design, the heater structure is stiffer and more robust than other related heaters in the art, thus allowing more options for its implementation.

A heater assembly comprises a container including a cylindrical portion that forms a chamber in which a flavor generating article is contained, and a heater arranged in a peripheral surface of the cylindrical portion. The container includes a first channel extending along a longitudinal direction of the cylindrical portion and located adjacently to the chamber in a direction intersecting with the longitudinal direction of the cylindrical portion, and a second channel extending through the chamber along the longitudinal direction of the cylindrical portion. The first channel is in communication with the second channel.

Provided are an article including a joint portion of a fluororesin having sufficient strength, and a method of producing the same. The article includes a joint portion including: a porous first layer of a first fluororesin; a second layer of a second fluororesin having a melting point lower than a melting point of the first fluororesin; and a non-porous third layer formed between the first layer and the second layer, the non-porous third layer including the first fluororesin.
