ASSEMBLY FOR DELIVERING VOLATILE FLUID TO SURROUNDING ENVIRONMENT

摘要

A method of activating a non-energised delivery assembly for a volatile fluid is described, the method comprising the steps of: loading a refill of volatile fluid into the delivery device wherein the refill comprises a reservoir chamber containing a volatile fluid and a vapour permeable membrane, and wherein the reservoir chamber is provided with at least one feed tube extending away from the reservoir wherein the feed tube is provided with a predetermined zone of weakness; and wherein the delivery device comprises a housing with an internal recess configured to releasably retain the refill of volatile fluid therein and an activation member within the internal recess; whereby the action of retaining the refill in the device causes the activation member to impinge against the refill to bend the refill at or adjacent a predetermined zone of weakness in said feed tube to bend said tube(s) to a snap angle of between >20° and <50° and/or to bend said tube(s) with a snap force of between 10-30N. A refill and a device for use with the claimed method are also described.
