Assembly for delivering volatile fluid to surrounding environment

摘要

A method of activating a non-energised delivery assembly for a volatile fluid, the method comprises the steps of loading a refill 10 of volatile fluid into the delivery device wherein the refill comprises a reservoir chamber 11 containing a volatile fluid and a vapour permeable membrane 16, and wherein the reservoir chamber 11 is provided with at least one feed tube 14 extending away from the reservoir 11 wherein the feed tube 14 is provided with a predetermined zone of weakness 15; and wherein the delivery device (1) comprises a housing with an internal recess (18) configured to releasably retain the refill of volatile fluid therein and an activation member (19) within the recess; and whereby the action of retaining the refill in the device causes the activation member (19) to impinge against the refill to bend the refill at or adjacent to a predetermined zone of weakness 15 in said feed tube 14 to bend said tube(s) to a snap angle of between 20-100° and/or bend said tube with a snap force of 10-50N. Also claimed is the refill 10 and the device (1).
