HUMIDIFYING CAPSULE FOR USE WITH TOBACCO PRODUCTS

摘要

A humidifier (10) for use with tobacco products comprises a closed capsule (12) fabricated at least partially from material comprising a thermo-mechanically expanded polymer membrane having micropores to render the material permeable to moisturising vapour such as water vapour, and a source of the moisturising vapour (14) encapsulated within the closed capsule. Vapour is then emitted to the surrounding environment through the closed capsule. The vapour source may be liquid water or may be water absorbed into a water- absorbing material inside the closed capsule. The capsule may have a shape intended to maximise its surface area for a given volume.
