Abstract
Abstract A flavor delivery article produces an aerosol. The article includes an outer container in the form of a tube and an inner container disposed within the outer container. The inner container contains liquid such as an alcohol-water mixture, and a delivery means such as a tube. An airflow acceleration means is located near the output region of the delivery means such that airflow through the outer container can disperse the liquid from the delivery means into the airflow in aerosol form.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
182 words
A flavor delivery article comprising: (a) an outer container providing a pathway for airflow therethrough; (b) an inner container disposed within the outer container and containing a liquid, the inner container having a delivery means having an output region for output of the liquid; (c) an airflow acceleration means located near the output region of the delivery means; and (d) a mouthend region; wherein the airflow acceleration means is a baffle in the form of a disk having an aperture therethrough; wherein the output region of the delivery means and the airflow acceleration means are arranged in a relationship such that puff induced airflow through the outer container experiences a pressure drop adjacent the output region of the delivery means relative to the pressure experienced by the liquid contained within the inner container, which pressure drop is sufficient to disperse liquid from the output region of the delivery means into the airflow to form an aerosol in the mouthend region; and wherein the output end of the delivery means extends through the aperture slightly beyond the output end surface of the disk.

Claim 3
Dependent Claim
128 words
A flavor delivery article comprising: (a) an elongated outer container having a mouthend; (b) an inner container mounted in the outer container and containing a liquid; (c) a delivery means mounted in the outer container, the delivery means being in flow communication with the inner container and having at least one passage therethrough for transferring the liquid from the inner container to a point nearer the mouthend; (d) means for providing for passage of air through the outer container; and (e) an airflow acceleration means located adjacent the opening of the delivery means in order to form an aerosol from the liquid in the delivery means upon puffing; wherein the opening in the delivery means extends slightly beyond the airflow acceleration means towards the mouthend of the article.
Claim 4
Dependent Claim
128 words
A flavor delivery article comprising: (a) an elongated outer container having a mouthend; (b) an inner container mounted in the outer container and containing a liquid; (c) a delivery means mounted in the outer container, the delivery means being in flow communication with the inner container and having at least one passage therethrough for transferring the liquid from the inner container to a point nearer the mouthend; (d) means for providing for passage of air through the outer container; and (e) an airflow acceleration means located adjacent the opening of the delivery means in order to form an aerosol from the liquid in the delivery means upon puffing; wherein the opening in the delivery means extends slightly beyond the airflow acceleration means towards the mouthend of the article.
Claim 5
Dependent Claim
133 words
A flavor delivery article comprising: (a) an elongated outer container having a mouthend; (b) an inner container mounted in the outer container and containing a liquid, wherein the container has a cross sectional area such that the liquid therein forms a meniscus across the cross sectional area of the inner container; (c) a delivery means mounted in the outer container, the delivery means being in flow communication with the inner container and having at least one passage therethrough for transferring the liquid from the inner container to a point nearer the mouthend; (d) means for providing for passage of air through the outer container; and (e) an airflow acceleration means located adjacent the opening of the delivery means in order to form an aerosol from the liquid in the delivery means upon puffing.
