Abstract
An apparatus for generating odor including a disk having a substrate with a dispersing material retaining at least one releasable aroma positioned with respect to the substrate. The dispersing material includes a structure, such as a plurality of openable pores, that is physically responsive to a stimulus such as heat or light. A device provides the stimulus to the dispersing material upon demand as a function of a signal, wherein the plurality of pores within the dispersing material are reversibly enlarged as a result of the stimulus.
Claims39
An apparatus for generating odor, the apparatus comprising:
- a substrate;
- a dispersing material comprising a compound having reversible properties, the dispersing material retaining at least one releasable aroma positioned on the substrate;
- and
- a device for providing a stimulus to the dispersing material upon demand as a function of a signal, wherein at least one physical property of the dispersing material is reversibly altered as a result of the stimulus so that the dispersing material responsively reacts to the stimulus resulting in a controlled release of aroma and subsequently returns to an unaltered state resulting in containment of the aroma.
