AI Technical Summary

Technical Problem

Existing aerosol generating articles often suffer from insufficient vapor generation and difficulty in positioning within aerosol generating devices, leading to a poor user experience.

Method used

The aerosol generating article features a substrate part with an aerosol generating substrate, a cooling part, and a wrapper that wraps both parts. The wrapper has a textured pattern creating air gaps between the wrapper and the substrate, enhancing vapor generation and heat transfer, while the textured pattern also aids in easy identification and accurate positioning of the article within the device.

Benefits of technology

The textured pattern on the wrapper increases vapor generation by forming air gaps and improving heat transfer, while facilitating easier and more accurate positioning of the aerosol generating article, thereby enhancing user experience.

Abstract

The present invention concerns an aerosol generating article (12) configured to operate with an aerosol generating device, extending along an article axis (X) and comprising: - a substrate part (25) comprising an aerosol generating substrate; - a cooling part (26) arranged successively with the substrate part (25) along the article axis (X); - a wrapper (31) wrapping together the substrate part (25) and the cooling part (26), and extending around the article axis (X); wherein the wrapper (31) comprises a wrapper substrate portion (45) covering the substrate part (25) and a wrapper cooling portion (46) covering the cooling part (26); wherein the wrapper substrate portion (45) comprises a textured pattern defining a plurality of voids between the wrapper (31) and the aerosol generating substrate.
