AI Technical Summary

Technical Problem

Existing non-combustible aerosol delivery systems lack effective control over aerosol characteristics and suffer from capillary leakage of aerosolisable material, affecting user experience and system performance.

Method used

The system incorporates grooves on opposing surfaces of the housing sections to inhibit capillary flow, eliminating the need for dedicated sealing elements like O-rings, thereby preventing leakage and enhancing manufacturing efficiency and reliability.

Benefits of technology

The solution effectively prevents capillary leakage, improves user experience, reduces waste, and lowers manufacturing costs by eliminating the need for additional sealing elements while maintaining system performance.

Abstract

Article (100) for use as part of a non-combustible aerosol provision system (10), the article comprising: a housing (101) having a first section (102) and a second section (103) which together form a reservoir (104) for an aerosolisable material (200), the first section and the second section being connected together to provide at least one pair of opposing surfaces(106, 108 and 107, 109); wherein a capillary channel (110) is provided between the opposing surfaces, and at least one of the opposing surfaces comprises at least one surface feature (111) for inhibiting or preventing capillary flow of an aerosolisable material from the reservoir through the capillary channel.
