Abstract
An aerosol-generating article (10) comprising a rod (20) comprising an aerosol-generating substrate (22); a filter (30) in axial alignment with the rod (20); a bridging element (40) comprising a first wrapper (42), the first wrapper circumscribing the rod (20) and the filter and securing the filter to the rod; and a cavity (44) located between the rod and the filter, the cavity (44) being partially delimited by the inner surface of the first wrapper (42) in a first portion of the bridging element (40), wherein the first portion of the bridging element (40) has a basis weight of 50 grams per square meter or greater.
Claims15
An aerosol-generating article comprising:
- a rod comprising an aerosol-generating substrate;
- a filter in axial alignment with the rod;
- a bridging element comprising a first wrapper, the first wrapper circumscribing the rod and the filter and securing the filter to the rod;
- and
- a cavity located between the rod and the filter, the cavity being partially delimited by the inner surface of the first wrapper in a first portion of the bridging element,
- wherein the first portion of the bridging element has a basis weight of 50 grams per square meter or greater.
An aerosol-generating article according to any one of the preceding claims, wherein the filter is circumscribed by the first portion of the bridging element.
A method of manufacturing an aerosol-generating article comprising:
- providing a rod comprising an aerosol-generating substrate;
- providing a filter;
- providing a bridging element comprising a first wrapper;
- and
- securing the filter to the rod using the bridging element such that the first wrapper circumscribes the rod and the filter in a spaced-apart relationship to form a cavity between the rod and the filter, the cavity being partially delimited by the inner surface of the first wrapper in a first portion of the bridging element,
- wherein the first portion of the bridging element has a basis weight of 50 grams per square meter or higher.
