The method includes creating a cavity between the first element and the second element. The method comprises inserting one or more plant seeds into the cavity by means of a seed inserter. The method includes defining a first element, a second element, and a cavity with an outer wrapper. The first element and the second element may be filter segments.
By separating the first element from the second element by means of a spacer wheel, a cavity can be created. The seed inserter may be conical.
The method may comprise loading the combiner with different preformed elements of the aerosol-forming article and combining the elements to provide the aerosol-generating article.
The method may include pre-forming the filter element with a cavity having seeds. Thus, the hopper may be loaded with a long mouth filter rod which is then cut into smaller mouth filter segments. The smaller filter segments may have a length of 10mm. Each smaller filter segment may then be cut in half to form two final filter segments, for example 5mm in length. The spacer wheel may then create a cavity between the two final filter segments on the perforated belt converging towards the final combining zone. On a perforated belt carrying filter segments, a seed inserter may insert one or more seeds before the two final filter segments and the seed-filled cavities therebetween are wrapped by the filter segment wrapper to form a filter element.
The filter element may then be combined with other preformed elements to form the final aerosol-generating article.
The invention also relates to an aerosol-generating article comprising plant seeds, preferably an HNB aerosol-generating article comprising plant seeds.
HNB articles may generally include less total mass of filter material than combustible sol-generating articles, which may reduce the environmental impact of the article and/or may promote biodegradability of the article. These effects may be synergistically enhanced when HNB preparations are used which have plant seeds, preferably in the cavity. High temperatures may adversely affect plant seeds. HNB products can operate at lower temperatures than flammable products. Thus, an article of manufacture that provides milder conditions to plant seeds may be provided. HNB products can operate under more humid conditions than flammable products. This may advantageously promote germination of the plant seeds after the HNB preparation has been used.
The aerosol-generating article may comprise a hollow mouthpiece tube, such as a helically wound paper tube, at the proximal end of the article. Adjacent to the mouth piece tube, the article may comprise a filter element, preferably wherein the filter element comprises a first filter segment and a second filter segment, wherein the second filter segment is arranged separate from and remote from the first filter segment to form a cavity between the first filter segment and the second filter segment, and wherein the filter element comprises one or more plant seeds arranged within the cavity. Adjacent to the filter element, the article may comprise a hollow tube, such as a spirally wound paper tube. The hollow tube may comprise one, two or more rows of vent holes, each row of vent holes being arranged circumferentially around the hollow tube in a cross section substantially perpendicular to the longitudinal axis of the article. The article may include a portion of an aerosol-forming substrate at a distal end thereof. One or more outer packages may be provided that define at least a portion of the aerosol-generating article.
