Description

Aromatic metal ornament and its manufacturing method {aroma metal ornament and manufacturing method of the same}

The present invention relates to a directional metal ornament. More specifically, the present invention is a directional metal decoration that emits a scent continuously for a long time, and can realize various forms of foolish appearance even at a simple process and low cost, and thus can be used for decorative or accessories of various belongings and directional metal decoration and its It relates to a manufacturing method.

The aromatic metal products that emit scents have been in the past, but suffered from the inherent problems that it is difficult to quickly penetrate the desired scent within a short time and that it is difficult to refill, that is, refill.

Recently, however, new products that can solve existing problems have been introduced to attract attention.

This product, called 'fragrance metal', is a preform manufactured by mixing a metal powder and a binder having an average particle size of 100 µm or more and a binder after pressing at room temperature at a pressure of 100 to 600 MPa as introduced in Korean Patent Application No. 10-1997-0063266. And the sintered in 120 minutes or less at a temperature in the range of more than 900 ℃ 1400 ℃ to show a porosity of 10 to 20% to form a porous metal sintered body, characterized in that the fragrance penetrates. In addition, some directional metal products have been introduced in Korean Patent Application Nos. 10-2001-0061313, 10-2002-0069868, 10-2006-0046719, etc. And a similar method of sintering at high pressure to form micropores, showing a common fragrance principle in which perfumes permeated into micropores are continuously evaporated to emit fragrance.

On the other hand, it is attracting attention as an ornament, as well as accessories of various belongings that the aromatherapy effect can be obtained by incorporating the fragrance metal into daily life. In this case, since the former case can be easily understood, a separate description is omitted, while the latter representative example is a so-called 'fragrance card' applied to a credit card.

1 is a perspective view of a general 'fragrance card', Figure 2 is a cross-sectional view of the II-II line of FIG.

As can be seen, a general 'fragrance card' represents a structure in which a fragrant metal 4 in the form of a thin plate is pressed into the surface of a conventional plastic credit card 2. At this time, the fragrance metal (4) comprises a plurality of micropores (6) as introduced in Patent Application No. 10-1997-0063266, etc., the user is exposed to the fragrance metal (4) exposed from the surface of the credit card (2) The fragrance is dropped to penetrate the pores 6 so that the fragrance is continuously released.

However, these aromatic metals also exhibit some disadvantages.

First of all, in terms of the manufacturing process, the high-temperature and high-pressure metal sintering step is indispensable, so the overall process is difficult, the cost is high, and the price of the product is high. This is especially a fatal weakness in the case of an accessory or a decoration which shows the production and consumption structure of the peeled off medium.

In addition, due to its unique porous structure, it is difficult to obtain a single article having a small thickness due to its strength against impact, and due to the limitation of the material, there are great restrictions on the shape and color that can be actually realized. This is another deadly weakness in the case of fashionable or short life cycle accessories or decorations.

The present invention has been made to solve the above problems. That is, the present invention is a directional metal decoration that emits scent continuously for a long time, and can express various forms of foolish appearance even at a simple process and low cost, thereby presenting a realistic and concrete method that can be used for decoration or accessories of various belongings. The purpose is to.

The aromatic metal ornament according to the present invention can scent continuously for a long time even with a relatively simple process and low cost. Furthermore, the directional metal ornament according to the present invention can express various forms of foolish appearance, and can be used as accessories of various belongings such as mobile phones and bags, bookmarks, earrings and necklaces as well as credit cards. wide.

Hereinafter, the present invention will be described in detail with reference to the drawings.

3 is a perspective view of one example of the use of the directional metal ornament 20 according to the present invention, showing a case applied to the credit card. 4 is an exploded perspective view of FIG. 3, and FIG. 5 is a cross-sectional view taken along line V-V of FIG. 3.

As can be seen, the directional metal ornament 20 according to the invention comprises a base 21 providing a recessed indentation space 22, one or more metal sheets 32 inserted into the indentation space 22 of the base 21 and Liquid cover 50, a metal cover 42 to cover and seal the indentation space 22 of the base 21.

Looking at each of them in detail as follows.

First, the base 21 is a basic material for the concave indentation space 22, the indentation space 22 is a liquid cover 50 is embedded with a metal sheet 32 to be described later to cover the metal cover ( It is a kind of directional space sealed by 42).

Therefore, the base 21 is sufficient to provide a concave indentation space 22, the indentation space 22 is sufficient if the metal sheet 32 and the liquid fragrance 50 is embedded and sealed with a metal cover 42, Each shape may be variously modified according to the purpose. However, in consideration of the fact that the liquid fragrance 50 is filled in the indentation space 22, the base 21 is preferably made of a metal or plastic material, which is a non-invasive material, to prevent unnecessary loss of perfume. The space 22 preferably represents an area and a depth enough to allow 2 to 10 sheets of metal sheets 32 to be freely embedded therein.

Next, at least one metal sheet 32 is embedded in the indentation space 22 of the base 21 together with the liquid perfume 50 to continuously maintain evaporation of the perfume 50 over a long time.

To this end, a plurality of first pores 34 penetrate the metal sheet 32, and preferably two or more are inserted into the indentation space 22 together. Therefore, when the liquid fragrance 50 is filled in the indentation space 22, the metal sheets 32 adhere to each other by surface tension, and the first pores 34 penetrated through the metal sheets 32 are capillary tubes. It is connected directly or indirectly like a capillary tube) to maintain evaporation of perfume for a long time.

At this time, if two or more metal sheets 32 are in close contact and connected to each other in a capillary structure, the size and shape of the first pores 34 need not be particularly limited. It is faster than necessary, and in the opposite case, the evaporation of the perfume is delayed more than necessary. Accordingly, the first pores 34 preferably have a diameter of 0.01 to 0.5 mm, provided that 3 to 7 sheets of the metal sheet 32 are embedded in the indentation space 22. (slit) or other various shapes.

Finally, the metal cover 42 covers and seals the indentation space 22 to complete the appearance of the directional metal ornament 20 according to the present invention, and at the same time, to gently diffuse the fragrance of the indentation space 22 to the outside for a long time. Play a role.

To this end, a plurality of second pores 44 penetrate the metal cover 42, and preferably cover the indentation space 22 with a size corresponding to the edge of the indentation space 22 through a predetermined adhesive layer. It is adhered to the surface of the base 21. Therefore, the fragrance of the indentation space 22 is gently emitted to the outside through the second pores 44 of the metal cover 42.

At this time, the size and shape of the second pores 44 also need not be particularly limited, but if the second pores 44 are too large, the fragrance is stronger than necessary and the fragrance is weakened more than necessary in the opposite case. Therefore, it is preferable that the second pores 44 have a diameter of 0.05 to 1 mm, and are not necessarily limited to a circle, but may have a slit or various other shapes having a corresponding width.

As a result, the aromatic metal ornament 20 according to the present invention emits a persistent fragrance over a long time. And when most of the fragrance 50 is evaporated to weaken the fragrance can be refilled by dropping the liquid fragrance 50 on the metal cover 42 to penetrate the indentation space (22). At this time, by properly adjusting the amount of use of the metal sheet 32 according to the depth of the indentation space 22 to close the metal cover 42 and the metal sheet 32 can shorten the penetration time of the fragrance, the same effect It is also possible to appropriately adjust the size of the second pores 44 to be obtained within the corresponding range.

6 is a flowchart illustrating a method of manufacturing a directional metal ornament according to the present invention, together with FIGS. 3 to 5.

First, the base 21, the metal sheet 32, and the metal cover 42 manufactured through separate processes are prepared. (St1, st2, st3)

In this case, the base 21 has a recessed space 22 formed therein, a plurality of first pores 34 penetrate the metal sheet 32, and a plurality of second pores 44 in the metal cover 42. Is penetrated.

For reference, the indentation space 22 of the base 21 may be implemented by casting of plastic or metal, or by pressing or grooving separately, all of which are based on a known technique, and thus will be described separately. Without this, it's easy to understand. In addition, the first and second pores 34 and 44 of the metal sheet 32 and the metal cover 42 may be embodied by galvanoplastics or photolithography followed by etching. These are also based on known techniques, but can be easily understood without a separate description, but preferably a method unique to the applicant can be used. This is discussed in detail in the relevant sections.

Next, at least one metal sheet 32 is inserted into the indentation space 22 of the base 21. (st11)

At this time, two or more metal sheets 32 are preferably inserted (st11).

Subsequently, the liquid perfume 50 is dropped into the indentation space 22 of the base 21. (st12)

At this time, the fragrance 50 is not particularly limited in viscosity or type as long as it is a liquid, and an amount sufficient to sufficiently wet the at least one metal sheet 32 using a dropper or the like is dropped into the indentation space 22. As a result, the metal sheets 32 embedded in the indentation space 22 are in close contact with each other, and each of the first pores 44 is directly or indirectly connected to form a capillary structure.

Subsequently, the indentation space 22 is sealed with the metal cover 42.

At this time, preferably, the metal cover 42 may be a metal sticker, thereby completing the directional metal ornament 20 according to the present invention. When the fragrance is weakened due to evaporation of most of the fragrance due to prolonged use, the liquid fragrance 50 may be dropped onto the metal cover 42 to be refilled by infiltration into the indentation space 22.

On the other hand, the metal sheet 32 and the metal cover 42 of the directional metal ornament 20 according to the present invention can be implemented in a unique method by the cause of the present invention in addition to known techniques such as electric pole or photolithography followed by etching. There was. For reference, Jeonju refers to a method of replicating something of the same shape as a prototype using electroplating, and refers to a thin film processing technique commonly used in semiconductors, such as photolithography followed by etching. Since it is a widely known method, a separate description is omitted.

7 to 12 are process cross-sectional views for explaining a unique method by the present applicant, and the following description may be commonly applied to both the metal sheet 32 or the metal cover 42.

First, the substrate 62 is prepared as shown in FIG. 7, and then a photoresist layer 64 is formed on one surface thereof.

At this time, since the substrate 62 is used as another electrode in the plating step to be described later, it is possible to form a metal layer on the surface of an insulating plate such as conductive metal or glass such as stainless steel, and the photoresist film 64 is formed by light. As a thin film of a photosensitive polymer material that causes a continuous polymerization reaction, it can be realized by using a known product commonly called 'dry film resist' or by applying and drying a predetermined photosensitive liquid.

On the other hand, preferably, before the formation of the photoresist film 64, fine uneven scratches may be generated on one surface of the substrate 62 to facilitate desorption, which will be described later. As described in detail in 2001-0060651, in contrast to general polishing for obtaining a smooth surface, the surface is roughened to replace a separate strike treatment and / or peeling film, the substrate 62 Sprinkle abrasives such as emery or molten alumina on the surface of the metal and rub it with a metal brush to cause scratches.

Subsequently, the mask 70 is disposed on the photoresist film 64 and exposed as shown in FIG. 8. When the exposure is completed, the mask 70 is removed and then developed with an appropriate developer.

In this case, the mask 70 includes a blocking unit 72 that blocks light and a transmitting unit 74 that transmits light, and the transmitting unit 74 is formed on the premise that the photoresist film 64 is a negative type. Corresponds to the first or second pores 34, 44. When developing with an appropriate developer, a predetermined photoresist pattern 66 in which portions corresponding to the blocking portions 72 of the mask 70 are removed can be obtained.

Meanwhile, the mask 70 may be a proximity type or projection type in addition to a contact type film type which is in direct contact with the photoresist film 64 as shown in the drawing. Also in step, the step and repeat (step and repeat) or step and scan (step and scan) method of reduction projection may be applied.

Subsequently, metal is plated on one surface of the substrate 62 on which the photoresist pattern 66 is formed as shown in FIG. 9.

At this time, in the plating, the wet electricity is applied to the substrate 62 and the metal material by immersing the substrate 62 and the metal to be plated, for example nickel, together in an electrolytic cell containing a predetermined plating solution. Plating methods can be used.

As a result, as shown in FIG. 10, the plating layer is filled between the photoresist patterns 66, thereby completing the substantial metal sheet 32 or the metal cover 42.

At this time, the plating layer is preferably grown slightly higher than the photoresist pattern (66).

Subsequently, as shown in FIG. 11, the adhesive film 72 having the adhesive property is adhered to the metal sheet 32 or the metal cover 42 of the plating layer, and then the metal sheet 32 or the metal cover 42 is removed. Separate from the 66 and the substrate 62.

Meanwhile, scratches exist on one surface of the substrate 62, and the metal sheet 32 or the metal cover 42, which is a plating layer, is grown higher than the photoresist pattern 66. Therefore, only the metal sheet 32 or the metal cover 42 is detached from the photoresist pattern 66 and the substrate 62 by the adhesion and detachment of the adhesive film 72. Even if a part is bonded to the adhesive film 72, the adhesion between the metal sheet 32 or the metal cover 42 and the adhesive film 72 of the metal is greater than that of the photoresist pattern 66, or the metal sheet 32 or There is no great force to separate only the metal cover 42.

As a result, as shown in FIG. 12, the metal sheet 32 or the metal cover 42 through which the plurality of first or second pores 34 and 44 penetrate is obtained.

In this case, the metal sheet 32 may be used by removing it from the adhesive film 72 and the metal cover 42 may be used by attaching or applying an adhesive layer having a relatively strong adhesive strength to the exposed surface.

Meanwhile, in the above description, the contents obvious to those skilled in the art will be omitted since it may obscure the gist of the present invention. For example, the step of cleaning the substrate 62 before the photoresist film 64 is formed on the substrate 62 is performed. May be added, and so-called bake may be performed as a heat treatment for increasing the strength of the photoresist pattern 66 after development. In addition, instead of applying scratches to one surface of the substrate 62, it is also possible to form a strike treatment and / or a peeling film, and the metal sheet 32 or the metal cover 42 grows higher than the photoresist pattern 66 during plating. It is also possible to remove the photoresist pattern 66 with a suitable chemical after plating instead.

Referring to the above description, the directional metal ornament 20 according to the present invention may have any number of forms depending on the shape of the base 21 and the metal cover 42, as well as the base 21 and the metal cover 42. It is easy to expect that various aesthetics can be expressed depending on the material and design of the).

As some examples thereof, FIG. 13 corresponds to a case in which the directional metal ornament 20 according to the present invention is used as an emblem for an advertisement effect. At this time, if necessary, a separate adhesive layer may be formed on the bottom of the base 21 to use itself as one attachment. In addition, FIG. 14 corresponds to a case where the directional metal ornament 20 according to the present invention is utilized as a bookmark and the like, and FIG. 15 corresponds to a case used as a pendant of a necklace. In addition, the directional metal ornament 20 according to the present invention can be variously used as a thin sticker or decorative ring attached to a mobile phone or the like, which can be easily understood by those skilled in the art without a separate drawing.

That is, the present invention may be variously modified, but all these modifications should fall within the scope of the present invention if they fall within the technical spirit of the present invention. The scope of the present invention is as set forth in the claims below.
