A controlled diffuser device may include a cover, a louver panel, a base member, and a base. The cover and the base are fixed to each other so as to sandwich the base member and the louver panel, while the base member and the louver panel may be configured to slide and engage with the upper surface of the base. The base member may include a material whose physical dimensions change when the fragrance component is diffused. Due to the static fixed and sliding engagement configuration, the louver panel operably blocks the cover aperture and selectively adjusts the degree of variable exposure of the base member as the physical dimensions of the base member change. Is done. Other embodiments may include a base configured to receive the base member and place the cover thereon. As the physical dimensions of the substrate member change, the cover may be moved relative to the base. [Selection] Figure 1【解決手段】 制御されたディフューザー装置は、カバー、ルーバーパネル、基体部材、及びベースを含んでよい。カバー及びベースは、基体部材及びルーバーパネルを挟むように互いに固定される一方で、基体部材及びルーバーパネルをベース上面に摺動させて係合させるように構成されてよい。基体部材は、芳香成分を拡散させると物理的寸法が変化する材料を含んでよい。静的な固定及び摺動係合の構成によって、ルーバーパネルは、基体部材の物理的寸法が変化すると、カバーのアパーチャを動作可能に遮って、基体部材の可変な暴露の度合いが選択的に調節される。他の実施形態は、基体部材を受け入れて、カバーを上に配置させるように構成されたベースを含んでよい。基体部材の物理的寸法が変化すると、カバーはベースに対して移動させられてよい。【選択図】図1
