A device that is adapted to discharge a volatile material includes a display frame with a front face and a rear face . An opening is disposed in the front face. A dispenser is disposed within the display frame. The dispenser comprises a blister holding a volatile material and a permeable membrane extends across an open end of the blister. The rear face includes an integral foot member actuable between first and second states. The permeable membrane is disposed adjacent the front face and prevents the release of the volatile material in a first condition and permits the release of the volatile material through the opening in a second condition.一種適於發散出一揮發性物質的裝置包括具有一前面以及一後面的一展示框架。一開口配置在該前面中。一分配器配置在該展示框架內。該分配器包括裝載一揮發性物質的一罩件,以及橫越該罩件之一開放端而延伸的一滲透膜。該後面包括可在第一及第二態樣之間起動的一體成型的一腳元件。該滲透膜配置成毗鄰該前面,並阻止該揮發性物質在一第一狀況下釋放出,且允許該揮發性物質在一第二狀況下通過該開口釋出。20‧‧‧分配系統22‧‧‧分配器24‧‧‧展示框架26‧‧‧前面28‧‧‧第一壁部份30‧‧‧蓋32‧‧‧穿孔部份34‧‧‧長形孔36‧‧‧底端38‧‧‧頂端40‧‧‧孔48‧‧‧不可滲透薄板
