摘要：
A method for delivering a volatile fluid in a continuous manner, over a period of time and without leakage, to the atmosphere is disclosed. The method includes activating a device by breaching a semi-rigid sheet to release volatile fluid to the atmosphere. The device includes a flexible sheet and a semi-rigid sheet that are sealed along their edges to form a closed pocket or reservoir for containing a volatile fluid. The semi-rigid sheet is sealed on a first side to a flexible sheet and sealed on a second side to a vapor permeable membrane. The semi-rigid sheet contains a volatile fluid in the reservoir during storage, preventing contact of the volatile fluid with the vapor permeable membrane before the device is activated. The semi-rigid sheet has a differential score to guide the bounds of an opening that is formed upon activation. Once activated, the vapor permeable membrane provides continuous emission of a volatile fluid from the device.
