BAC KGROU ND

The use of perfumes goes back thousands of years and is a major industry. E ssenti al oi I s and scents i n I ow vapor pressure carri ers, such as al cohol are ty pi cal ly applied to clothing or the skin, often at the wrist behind the ears or to the chest.

The effect of the perfume usual ly lasts a number of hours.

Perfumes are used to provide a pleasant scent to the wearer that obscures unpl easant smel I s, rather I i ke the nosegays that were carri ed i n medi eval ti mes. They are also used so that the wearer gives off a pleasant smell, masking the natural body odour.

Over the years there have been various attempts to incorporate perfume in jewelry of one sort or another.

For example US 4,159,631 titled "Perfumed vapor dispensing jewelry" describes an article of jewelry for dispensing perfumed vapors comprising: a hollow housi ng havi ng upper and I ower porti ons coupl ed together to form the housi ng, the lower portion forming a reservoir for containing a quantity of perfume; coupling means attached to said housing for coupling the jewelry to another object a central disc located inside said housing; support means for supporting said disc in the housing; a plurality of orifices located in the upper portion of the housing through which perfumed vapors may exit a central orifice located in the upper portion of the housing through which perfume may be introduced into the housing; the disc having a plurality of cutouts, each said cutout being filled with absorbent material; and wick means extending from said absorbent material into said lower portion.

Typically the absorbent material is a gauze. The perfume may be added via the orifice using an eye dropper or the like. Organic pads for the perfume have to be replaced regularly which requires them to be removable. Gauzes and pads are not particularly aesthetic. This and the need to replace them makes such jewelry impractical.

Another early patent US 4,452,052 titled "Perfuming means for jewelry" describes an earring structure is disclosed having an interior compartment which houses a removabl e perfume cartri dge. The perfume cartri dge compri ses a cartri dge base containing perfumed material, and a rotatable top piece having an aperture through which fragrance may escape from the perfumed material to the ambient. Rotation of the top piece relative to the cartridge base changes the aperture area which is exposed to the perfumed material, thus permitting the wearer to block the escape of fragrance when desired and providing an adjustable range of fragrance strength.

French patent no. FR2409025 titled "Perfumed piece of jewelry" describes a sintered metal jewel such as ring or brooch and a method for impregnating the piece of jewelry with perfume that consists of impregnating the sintered metal ornament with an essential oil which is mixed with alcohol. The sintered metal jewel is placed inside a water and air-tight container in which a vacuum is produced. The essential oil is inserted into the container which is then placed in the air. The container is emptied of excess oil, and the ornament is removed.

Sintered metal is porous but consequently is generally not very decorative.

The method of impregnation, requiring vacuum is not very practical.

There have been vari ous attempts to make perfumed jewelry out of other materials.

US 6,381,984 (B1) to Russo and Russo titled "Scented jewelry"

describes a rechargeable article of jewelry that dispenses perfumed vapors and has a chamber formed from housing members. The housing members are made of a material which contains the perfumed vapors in the chamber and allows for releasing them into the atmosphere. A nugget of unglazed ceramic material is provided in the chamber and is of a size less than the chamber so that it is free to move inside the chamber and al I ow ai r to pass around the nugget. The chamber has apertures therei n through which an aromatic liquid, such as perfume, can be deposited on and absorbed by the nugget. The apertures also allow air to circulate around the nugget and generate perfumed vapors which may exit the chamber through the apertures. The nugget is larger than any of the apertures so the nugget is retained in the chamber.

There have been other attempts to i ncorporate unglazed perfume i impregnated ceramics within cages as a type of jewelry.

C N105615167 (A) is titled " perfumed ceramic ornament subjected to surface sandblasting and carving and manufacturing method of perfumed ceramic ornament" The invention relates to jewelry and an ornament in particular to a piece

of perfumed cerami c j ewel ry and ornament subj ected to surface sandblasti ng and carving and a manufacturing method of the perfumed ceramic jewelry and ornament and provides the perfumed ceramic jewelry and ornament subjected to surface sandblasting and carving and the manufacturing method of the perfumed ceramic jewelry and ornament so that a user can carry the spreading perfume while weari ng the cerami c j ewel ry and ornament. The cerami c j ewel ry and ornament has the attractive and fashionable appearance, and meanwhile, the functionality and the i nteresti ngness of the j ewel ry and ornament are i improved.

U S 9,315,422 ( B 2) to G oedermans and V an V een descri bes perfumed stones adapted to store perfume so as to release the smell over an extended period, and a method of manufacture of perfumed stones. The stones find particular suitability in perfumed jewelry. The perfume stone is designed for wearing in a pendant and has a composition comprising calcium sulphate, perfume and a settable material compri si ng Port! and cement and si I i ca. The 'stone' i s f abri cated i n the shape of an 8 sided diamond and is 8mm across the top face, 12 mm high and 3.5 mm across the bottom face. It is 14 mm in its widest point and weighs 1.7 grams. It is capable of absorbing about 0.2 g of perfume.

The above stone is sold by PerfumedJ ewelry.com and provides an artificial porous reservoir that the suppliers refer to as a jewelstone which can be sprayed with one's favorite perfume. Alternatively, they provide jewel stones that are

prei impregnated with one of over a hundred popular commercial fragrances from companies such as Dior, Kalvin K lein, Prada, Chanel, and the like.

The jewelry available are various designs of cages into which a jewelstone is inserted. The cages are made from silver, and optionally gold plated with 10K gold, either natural or rose coloured. The cages may be worn on a chain as a pendant on an earing or on a bracelet

The so-cal I ed j ewel stone, and al I the cerami c nuggets are ungl azed so as to be porous. Although possibly cast into a faceted form like a gemstone, they do not refract light or even reflect it particularly well. The cage around the ceramic may be decorative, but the ceramic insert itself is not.

US9272333 (B2) to TAISEI KOGY 0 CO LT D titled "Method of making a porous sintered body, a compound for making the porous sintered body, and the porous sintered body" describes a method of making a porous sintered body that i ncl udes a formation step wherei n a si nteri ng compound whi ch contai ns a bi nder and a sinterable powder material is molded into a predetermined shape; degreasing steps where the binder is removed from the formed body, and a sintering step wherein the degreased body after the degreasing step is sintered into a sintered body. The binder contains a component which drains at a temperature higher than a draining

temperature of the pore formation materi al . The pore formation material is drained in the degreasing step, with part of the binder remaining un-drained. This enables the manufacture of highly porous sintered bodies, that are highly accurate in shape and dimensions.

Porous metals and ceramics may be impregnated with scents such as perfumes but are not decorative. There is thus a need for perfume containing jewelry and the present invention addresses this need.

BRIE F DE SCRPTION OF FIGU RES

F or a better understand! ng of the i nventi on and to show how it may be carri ed into effect reference will now be made, purely by way of example, to the accompanying drawings.

With specific reference now to the drawings in detail, it is stressed that the particulars shown are by way of example and for purposes of illustrative discussion of the preferred embodiments of the present invention only, and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the invention. In this regard, no attempt is made to show structural details of the invention in more detail than is necessary for a fundamental understanding of the invention; the description taken with the drawings making apparent to those skilled in the art how the several forms of the invention may be embodied in practice. In the accompanying drawings:

F ig. 11 is a schemati c i 11 ustrati on of a gemstone i n a setti ng comprisi ng a porous material, and

Fig. 12 shows a porous material with machined indentations and worked and polished outer surface.

DE SCRIPTION OF E M BODIM E NTS

W ith reference to F ig. 1 , a S E M (scanni ng el ectron mi croscope) mi crograph of a porous stainless steel 5 formed by sintering is shown. The pores 10 shown are typically about 40 microns in diameter but could be anywhere from 10 to 70 microns in diameter depending on the sintering temperature, pressure, amount of binder, particle size, and other parameters. Other materials, such as nickel and copper, can be made by si mi I ar processi ng.

It has been found that such porous metals and alloys may be impregnated with scents and perfumes, which are typically essential oils and alcohol, and such porous metals can absorb relatively large quantities of perfume.

Metals are shiny. To create a mirror finish, one typically has to polish a metal to a surface roughness of less than 3 microns. Porous metals with pores that are larger than 1 or 2 microns do not reflect light well, and appear dull. Consequently they have I i mi ted val ue as jewelry.

Aspects of the invention are directed to providing pieces of jewelry that comprise a combination of at least one porous and one non- porous metallic section. The porous section may be i mpregnated with perfume whi ch evaporates over ti me, providing a pleasant fragrance to the wearer and from the wearer.

Typically both the non-porous and the porous metallic components or sections comprises stainless steel which may be polished to an attractive finish, and is easily worked using CNC and other techniques for mass- production. However, they may comprise other metals or alloys such as brass, gold and silver, for example.

Various pieces of jewelry may be fabricated from combinations of non-porous metal that can be polished to high shiny finishes, and porous metals that provide a pleasing contrast and may be impregnated with perfume. These include necklaces, pendants, bracelets, finger rings, earrings, nose- rings, eyebrow piercings, nipple piercings, genital piercings, toe-rings, anklets, chokers, chains, watch cases and watch straps, for example. Any and all such pieces of jewelry could include at least one porous metallic section to provide visual contrast with a non porous section, and which may be impregnated with a scented fluid.

The porous metal may be inset into a polished, not porous mount providing a raised decorative insert or inlay. Indeed, as described in IL 246690, the porous metal element may be fabricated into a multifaceted shape similar to the cut of gemstones. Such matt porous, perfume impregnated elements may be inset into watch straps and pendants.

Generally, porous metal is cast into desired shape prior to sintering and the surfaces are matt. With reference to Fig. 2, a porous metal insert 12 fashioned into a decorative element such as gemstone cut Some facets 14, 16 on the top of the insert may be machined, after sintering which makes them more reflective. In addition, the porous metal insert may be coated, typically using chemical vapor deposition or physical vapor deposition (CV D or PV D) prior to or post polishing. The coating tends to lower the surface roughness by smoothing the topography and this increases the reflectivity of the surface.

With reference to Fig. 3, in some embodiments, the at least one porous metallic section 20 is inserted into a non-porous metallic frame 22 which may include a cover 24 of non porous metal with apertures 26 covering the porous metallic section 20. A backing plate 28 may be fitted into the frame 22 behind the porous metal section 20 to seal the piece of jewelry. If the porous metallic section 20 is

impregnated with perfume it will be released through the apertures 26. As shown in F ig. 4, the non-porous metal cover 24 may be highly pol ished, with the apertures to the porous metal insert 20 being light absorbing and appearing darker.

In Fig. 5, a disk shaped pendant 30 is shown that consists of a woven grid of metal 34 withi n a frame 32. The frame may i ncl ude engravi ngs 36, gemstone i nserts 38 and other decorations. As shown in Fig. 6, the pendant 30 includes a porous metal insert 40 sandwiched between the back 42 and woven grid 34. The apertures in the grid 34 allow the porous metal insert 40 to be impregnated with perfume and allows the fragrance to be released. The back 42 may be press-fitted, soldered, or screwed into the frame 30 usi ng a threadi ng.

As shown i n F ig. 7, i nstead of a woven gri d, a pattern or design 44 may be laser cut from a cover plate 34 to provide a design with apertures 46 that enable the scent to evaporate from a porous metallic component (40 fig. 6).

Pendants including porous metal sections may have other shapes. With reference to Fig. 8, an exploded view of an oblong pendant 48 is shown. The pendant consi sts of an obi ong pol i shed frame 50 and may i ncl ude a lattice 51 or other el ements that cover the porous metal insert 60 with or without a grid 54 therebetween with a back cover 52 press fitted, soldered or otherwise attached to the back of the frame 50. The grid 54 may be a woven grid and fairly dull, or as shown in figs 9 and 10, different designs may be machined into a grid covering the porous metal insert. If the designs are machi ned by cutting away elements 60 from a flat surface 62, the remaining material of the flat surface 62 may be polished to a shiny finish.

With reference to Fig. 11, in some embodiments, the porous metallic section 64 is a setting for a gemstone 66 which may be precious, semi-precious, artificial, costue jewelry, etc. Since light may be reflected internally by the gemstone 66, the matt surface of the porous material 64 of the setti ng is not unsightly and contrasts wel I with the sparkl i ng j ewel .

The non porous section may be fabricated from a range of metals and alloys commonly used for jewelry such as brass, gold, silver and stainless steel.

Similarly, the porous section may be fabricated from stainless steel, brass, gold or silver. One fabrication technique using powder sintering is described in US 9,272,333 to Tasai Kogyo Ltd.

As shown in Fig. 12, the surface of a porous material 68 may be machined to provide light absorbing indents 70 and pressed, polished light reflecting surfaces 72.

Thus persons skilled in the art will appreciate that the present invention is not limited to what has been particularly shown and described hereinabove. Rather the scope of the present invention is defined by the appended claims and includes both combinations and sub combinations of the various features described hereinabove as well as variations and modifications thereof, which would occur to persons skilled in the art upon reading the foregoing description.
