Abstract

An additive assembly for an e-vaping device includes an adsorbent material that includes adsorbed carbon dioxide. The additive assembly may be in fluid communication with a vaporizer assembly that forms a generated vapor. The adsorbent material may release the carbon dioxide into the generated vapor based on at least a portion of the generated vapor adsorbing on the adsorbent material. The additive assembly may include a flavor material including a flavorant. The adsorbent material may generate heat based on at least a portion of the generated vapor adsorbing on the adsorbent material, and the flavor material may release flavorant into the generated vapor based at least in part on the heat generated by the adsorbent material. One or more of the adsorbent material and the flavor material may be included in beads. Adsorbent material and flavor material may be included in multiple additive structures within the additive assembly.

First claim

We claim:

1 . An additive assembly for an electronic vaping device (EVD), the additive assembly comprising:
an adsorbent material including adsorbed carbon dioxide, the adsorbent material configured to release the adsorbed carbon dioxide into a vapor based on at least a portion of the vapor adsorbing on the adsorbent material, the adsorbent material further configured to generate heat based on the portion of the vapor adsorbing on the adsorbent material; and a flavorant held within a portion of the adsorbent material, the flavorant configured to be released based at least in part on absorbing the heat generated by the adsorbent material, wherein the adsorbent material includes a first portion, a second portion, and a third portion, the first portion, second portion, and third portion include at least one material of the adsorbed carbon dioxide and the flavorant, respective outer surfaces of the first portion and the second portion at least partially define a first passage between the first portion and the second portion, the first portion and the second portion are configured to direct at least a portion of the vapor through the first passage, and the third portion includes a third outer surface orthogonal to the first passage such that the portion of the vapor flowing through the first passage impinges upon the third outer surface of the third portion.

2 . The additive assembly of claim 1 , wherein
the adsorbent material includes the first portion and the second portion separate from the first portion, the first portion of the adsorbent material includes adsorbed carbon dioxide, and the second portion of the adsorbent material is down stream from the first portion and includes the flavorant.

3 . The additive assembly of claim 1 , wherein the first portion and the second portion define a channel extending longitudinally through the adsorbent material.

4 . The additive assembly of claim 1 , wherein
the first portion of the adsorbent material includes adsorbed carbon dioxide and extends in a longitudinal direction, and the second portion of the adsorbent material includes the flavorant and is spaced apart from the first portion, the second portion extending parallel to the first portion.

5 . The additive assembly of claim 1 , further comprising:
a plurality of additive modules removably coupled together, each of the plurality of additive modules including,
a separate portion of the adsorbent material,
a housing,
complementary, respective interface surfaces, and
a conduit at least partially defined by the complementary, respective interface surfaces.

8 . The e-vaping device of claim 7 , further comprising:
a plurality of additive modules removably coupled together, each of the plurality of additive modules including a separate one of the adsorbent material and the flavorant.

9 . The e-vaping device of claim 8 , wherein
the additive assembly includes at least a first and second additive structures;
the first and second additive structures include at least one of the adsorbent material and the flavorant; and
the first and second additive structures at least partially define a boundary of at least one passage between the first and second additive structures.

10 . The e-vaping device of claim 6 , wherein the power supply section includes a rechargeable battery.

11 . A cartridge for an e-vaping device, comprising:
a vaporizer assembly configured to form a generated vapor, an adsorbent material in fluid communication with the vaporizer assembly, the adsorbent material including adsorbed carbon dioxide, the adsorbent material configured to release the adsorbed carbon dioxide into a vapor based on at least a portion of the vapor adsorbing on the adsorbent material, the adsorbent material further configured to generate heat based on the portion of the vapor adsorbing on the adsorbent material; and a flavorant held within a portion of the adsorbent material, the flavorant configured to be released based at least in part on absorbing the heat generated by the adsorbent material, wherein the adsorbent material includes a first portion, a second portion, and a third portion, the first portion, second portion, and third portion include at least one material of the adsorbed carbon dioxide and the flavorant, respective outer surfaces of the first portion and the second portion at least partially define a first passage between the first portion and the second portion, the first portion and the second portion are configured to direct at least a portion of the vapor through the first passage, and the third portion includes a third outer surface orthogonal to the first passage such that the portion of the vapor flowing through the first passage impinges upon the third outer surface of the third portion.

12 . The cartridge of claim 11 , wherein
the adsorbent material includes the first portion and the second portion separate from the first portion, the first portion of the adsorbent material includes adsorbed carbon dioxide, and the second portion of the adsorbent material is down stream from the first portion and includes the flavorant.
