The present invention relates to a combined air freshener and ornament or home decoration formed of one or more polymer resin(s) loaded with a fragrance oil or oils or other fragrance material(s). The air freshener releases fragrance into the air. The air freshener converts from a self-standing holiday figure or home decoration to a tree ornament or other hanging ornament with a releasably engageable hook or support stand.
Effective continuous action air fresheners release a sufficient amount of fragrance such that for a given enclosed space, such as a room or a motor vehicle passenger compartment, the fragrance is readily perceptible when someone enters that space. In addition effective air fresheners deliver fragrance for an acceptable period of time, such as 30 to 60 days. Moreover, such air fresheners should maintain fragrance character over this time period, such that the odor impression of the fragrance when the air freshener is activated as compared to the fragrance character at the end of the functional life is relatively the same.
Consumers may prefer portable air freshener devices that may be installed quickly and removed quickly from living spaces. Devices that may be moved from one location to another location easily also are preferred. Consumers further may prefer air freshener devices with outer configurations that more discretely fit within a living space, or configurations that add decorative flair during holiday seasons. Improvements to air freshener devices for household use continue to be sought.
Christmas tree ornaments are hung to conifer tree branches with Christmas tree hooks, ribbons, string, bands and clips, such as clips with spring-biased jaws. See, e.g., U.S. Pat. No. 6,155,526 for a hook-type hanging device. See, e.g., U.S. Pat. Nos. 4,886,688 and 7,275,727 for band-type hangers for ornaments. Improvements for ornaments and means for hanging ornaments continue to be sought.
An air freshener or air freshener and ornament combination has a body formed of a fragranced polymer that defines at least one receiving hole. A support stand is shaped so that its proximal end may be removably engaged in the receiving hole to position said body in a standing display configuration with the body supported on a substantially flat support surface, and so that its distal end may be removably engaged in the receiving hole to position said body in a hanging display configuration when the hook is engaged onto or around a support structure. The proximal end of the support stand may terminate at a first plug, and the distal end of the support stand may terminate at a second plug. Each plug may force-fit within the at least one receiving hole. In one embodiment, the support stand forms a hook or candy-cane shape with a curved portion and a straight portion.
In one particularly preferred embodiment, the air freshener includes an internal skeletal structure and the fragranced polymer forming the body is molded onto or over at least portions of the skeletal structure. The skeletal structure may be formed of metal or wire, or may be formed of a polymer such as but not limited to polypropylene and copolymers thereof. The skeletal structure may define raised portions that remain exposed after the fragranced polymer is molded onto or over the skeletal structure. Preferably the skeletal structure and, particularly, the raised portions, do not contain fragrance material. The raised portions may correspond to one or more decorations or features of the air freshener or air freshener and ornament, such as face features, clothing features, footwear features, etc.
The fragranced polymer may be any one or a mixture of polymers. Representative polymers include: polyvinylchloride, polyethylene, low density polyethylene (LDPE), high density polyethylene (HDPE), thermoplastic elastomer (TPE), polypropylene, ethylene vinyl acetate, ELVAX® EVA ethylene vinyl acetate copolymer, acetate, butyrate, propionate, silicone, copolymers thereof, and mixtures thereof. The polymer preferably is compounded, blended or mixed with one or more fragrances to form the fragranced polymer.
The support stand may be formed of a polymer, such as polypropylene and copolymers thereof. Preferably, the support stand does not contain fragrance materials.
The air freshener or air freshener and ornament may be formed into an ornamental shape. Representative, but not limiting, shapes include: gingerbread man, gingerbread woman, baby gingerbread man, gingerbread house, gingerbread cookie, Christmas cookie, Santa Claus, Mrs. Claus, reindeer, Christmas tree, snowman, snow woman, poinsettia, snowflake, and star.

A “fragrance material” may be any material that has a smell or odor. Most conventional fragrance materials are highly volatile essential oils. Even those which are less volatile contain highly volatile “top note” fractions which preferably are retained in the composition during processing to obtain desired fragrance power and olfactory impact by the resultant molded article. A fragrance material or a combination of fragrance materials that is compatible with the selected resin composition is preferred. The fragrance material may be a synthetically formed material or may be a naturally derived oil such as, but not limited to, the oil of Bergamot, Bitter Orange, Caraway, Cedar Leaf, Cedar Wood, Champacc, Cinnamon, Frankincense, Geranium, Lavender, Mimosa, Orange, Orignaum, Patchouli, Rosewood, Sandalwood, Vanilla, Violet, White Cedar, Ylang Ylang, Limonene, menthol, eucalyptus, camphor or the like. The particular essential oil or combination of oils to be used depends upon the particular fragrance desired for emission by the product formed.
Alternatively or additionally, the fragrance material may comprise or act as a volatile insecticide and/or insecticidal synergist or attractant or repellant, such as pyrethrum, octenol, linalool, mint oil, or a bacteriostat or pheromone. Alternatively or additionally, the fragrance material may comprise or act as a vaporous remedy for respiratory conditions, such as a vapor to relieve symptoms of colds and allergies.
Available fragrance materials are catalogued and described in references and databases known to persons skilled in the art. For example, a database is maintained by the Research Institute for Fragrance Materials at www.rifm.org. Fragrance material suppliers include Takasago International Corp. (Rockleigh, N.J.) and Symrise (Teterboro, N.J.). Exemplary synthetic fragrance materials are described in U.S. Pat. Nos. 4,411,829; 4,314,915 and 4,434,306. Preferred amounts of fragrance loading in resin are from about 5% to about 45% by weight of the resin.
Colorants (such as pigments known for use with thermoplastic and thermoset resins) may be incorporated into the polymers to improve aesthetics. Examples of suitable colorants also include any water-based colorant such as food coloring, and Reactint polymeric colorant from Milliken Chemical (Spartanburg, S.C.).
Other additives may be incorporated into the polymers as desired, including one or more plasticizers, one or more stabilizers, and optionally one or more lubricants. Decorative substances also may be entrained or mixed into the polymer(s), such as but not limited to glitter or other particles.
After molding, the fragranced polymer material forming the ornament body preferably has a hardness value (durometer) in the range of 30 to 90, preferably 60 to 70 on the Shore A scale.
The ornament body 12 has a front face 28 and a rear face 30 opposite of the front face. The ornament body 12 may have decorative elements attached or applied thereto or co-molded therewith. Referring to
Other types of decorative elements may be applied to the ornament body 12 as desired. In the embodiment of
In one preferred embodiment of the invention, the fragranced polymer is over-molded onto a skeletal structure 80, such as shown in
In this preferred embodiment, raised portions 88, 90, 92, 94, 96, 98 and 100 correspond to decorations in the finished air freshener. Raised portions 88, 90 and 92 correspond to face decorations 34. Raised portions 94 correspond to button decorations 36. Raised portions 96 correspond to arm decorations 40. Raised portions 98 correspond to leg decorations 42. In addition, raised portions 100 comprise feet decorations of the ornament/air freshener.
The raised portions 100, that may comprise feet decorations, correspond to contacting point(s) upon which the air freshener or ornament rests on a support surface when the ornament is in the standing display configuration of
Another advantage of the skeletal structure 80 as shown is that the through holes 82 permit the fragranced polymer forming the front portion of the ornament to integrally connect with the fragranced polymer forming the back portion of the ornament. Fragranced polymer materials tend to shrink as fragrance oils dissipate from the material. With this skeletal structure and fabrication method, the fragranced polymer material of the front and back portions of the body are chemically joined together via the through-holes, and therefore, maintain product integrity despite fragranced polymer material shrinkage.
Preferably, the skeletal structure 80 is formed of a resin, such as but not limited to, a thermoplastic elastomer including polypropylene, polyethylene, ABS, nylon, or silicone. Alternatively, the skeletal structure 80 may be configured of bent wire or molded metal.
Whether the air freshener and ornament is formed with or without a skeletal structure, the air freshener and ornament may be converted alternately as desired from a hanging configuration to a standing display configuration. The ornament body 12 defines a receiving hole or cavity or recess 32. Referring to
When in the hanging configuration, as shown in
Most preferably, the foot decoration 42 or 100 is formed of a polymer material that does not include fragrance oil so that when the foot decoration 42 or 100 contacts a support surface it does not mar such support surface with fragrance oil. Most preferably, the decorations 34, 36, 40 or the raised portions 88, 90, 92, 94, 96, 98 and 100 are formed of a polymer material that does not include fragrance oil so that when these decorations or raised portions contact other surfaces, they do not mar such surfaces with fragrance oil.
The invention has been illustrated with particular reference to attaching or engaging the combined air freshener and ornament 10 to tree bough or branch. The combined air freshener and ornament 10 may be useful in alternative environments of use, such as attached or clipped to curtain rods in closets or cabinets, or to motor vehicle door handles, curtain rods, closet rods, hangers, shelving, shelving support posts, drawer pulls, drawer handles, belt loops, shoes, shoe racks, hampers, gym bags, lockers, shower doors, towel racks, trash cans, pipes, wires, tables, and carts, and is not intended to be limited to the environment of use illustrated here.
Alternatively, the combined air freshener and ornament according to the invention may be installed on a belt or on a belt loop or other clothing item and worn as a personal air freshening device. Such embodiment has particular appeal where the fragrance material comprises a volatile insecticide, or where the fragrance material comprises a cold or allergy vapor remedy.

Air fresheners may be tested for fragrance character and fragrance strength using a fragrance panel test known in the fragrance industry. A sample air freshener product is suspended in a room with dimensions of 25 feet by 16 feet by 9 feet. A panel of at least four persons ranks the strength and character of the aroma emitted by the various air freshener products on a scale of 0 to 5, with 5 being the strongest and 5 being the closest in character to the fragrance oil. The fragrance power and fragrance character are observed over a four-week period. The fragrance power values are averaged, and the fragrance character values are averaged. Products that receive average rankings of 3 and above for the entire testing period are satisfactory for use as continuous action room air fresheners.
Air fresheners may be tested for suitability and durability for use as air fresheners. For example, the air fresheners may be frozen for at least 12 hours and thawed over a repeated number of cycles (such as 3 cycles) to determine whether fragrance material exudes from the polymer upon thawing. Air fresheners may be heated to an elevated temperature of at least 120° F. and held for 4 weeks at such temperature, in packaging and outside of packaging, to determine whether fragrance exudes and whether fragrance strength and fragrance character degrade. Air fresheners may be exposed to ultraviolet light testing for at least 4 weeks to determine effect of light on product color and fragrance character.
While preferred embodiments of the invention have been described and illustrated here, various changes, substitutions and modifications to the described embodiments will become apparent to those of ordinary skill in the art without thereby departing from the scope and spirit of the invention.
