ABSTRACT:
An aromatic decorative figure or other object formed of foam plastic material having dispersed throughout its cellular structure a relatively large amount of a volatile liquid fragrance. When the figure is exposed to the atmosphere, it continuously exudes the fragrance for a prolonged period, in the course of which the figure proceeds to shrink as a result of liquid loss, thereby indicating the approaching exhaustion of the fragrance. In one embodiment, the figure is created in situ by injecting a charge of a foam-forming mixture having the liquid fragrance dispersed therein into the cavity of a blister pack whose transparent blister is configured to assume the contours of the desired figure. The injected mixture expands within the cavity to form a figure which conforms to the contours of the blister and is cured therein. The resultant foam-plastic figure is effectively sealed within the pack to prevent the escape of fragrance, the pack also serving to display and protect the figure.
