ABSTRACT:
A scent dispersing apparatus, such as a mat, capable of enclosing a scent-containing element inside an air-filled cavity. A housing contains a means for air ventilation, such as small air holes, for dispersion of scent. When the housing receives a force, such as a user exerting pressure upon on the housing, air is pushed from the air cavity outward through the air holes, thereby, dispersing scent contained in the scented insert. Additional air enters the air cavity once the pressure is released through an elastic rebound effect.
