UMIDIFICADOR DESCARTÁVEL PARA USO COM PRODUTOS DE TABACO E EMBALAGEM PARA PRODUTOS DE TABACO

摘要

A disposable humidifier for use with tobacco products comprises a moisture-releasing element that emits water vapour and a semi-permeable one-way membrane that encloses the moisture-releasing element and transmits water vapour from the moisture-releasing element and substantially blocks the passage of water vapour and liquid water to the moisture-releasing element. The humidifier may also have an outer layer that is impermeable to water vapour and which is removed or breached before use of the humidifier in a package or container of tobacco product. The humidifier may be incorporated into the package.
