Abstract
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.

Claim 1
Independent Claim
115 words
An aromatic, foam-plastic, decorative, three-dimensional article comprising: (a) an envelope configured to assume the contoured three-dimensional form of a decorative object, said envelope forming a mold cavity and having a port therein to admit a charge of foam-forming mixture having a liquid fragrance dispersed therein which expands under gas pressure to ill said cavity and conform to the contours of the envelope, aid envelope having minute apertures therein to relieve aid gas; and (b) a foam-plastic object formed in situ in the cavity from said mixture admitted through said port and conforming to the contours of the envelope, aid object exuding said fragrance and said envelope being at least partially transparent to expose the object.
Claim 2
Dependent Claim
115 words
An aromatic, foam-plastic, decorative, three-dimensional article comprising: (a) an envelope configured to assume the contoured three-dimensional form of a decorative object, said envelope forming a mold cavity and having a port therein to admit a charge of foam-forming mixture having a liquid fragrance dispersed therein which expands under gas pressure to ill said cavity and conform to the contours of the envelope, aid envelope having minute apertures therein to relieve aid gas; and (b) a foam-plastic object formed in situ in the cavity from said mixture admitted through said port and conforming to the contours of the envelope, aid object exuding said fragrance and said envelope being at least partially transparent to expose the object.
Claim 3
Dependent Claim
32 words
An article as set forth in claim 1, wherein said mixture as it expands is extruded through said apertures to form tentacles which project outside of the envelope and exude said fragrance.
