Improvements relating to tobacco smoke filter elements

摘要

This invention relates to a method which provides in a cigarette filter element a capsule containing a deodoriser. The capsule is resistant to the handling endured before and during smoking, and is ruptured to release or expose the deodoriser after smoking has occurred and upon extinguishing of the smoked cigarette. The deodoriser may comprise neutralising or masking agents, or mixtures of both. <IMAGE>
