  However, when a silver sintered body is used instead of bulk silver, a metallic glossy surface cannot be obtained, so that there is a problem that the appearance is not good and the commercial value is low. In addition, when trying to fix the sintered body to the seat with an adhesive, the adhesive is sucked into the gaps of the sintered body, and there is a problem that the adhesive strength is low.

  Further, the fragrance-generating product described in Patent Document 1 has a problem that the fragrance is rapidly evaporated and the fragrance cannot be generated over a long period of time because the voids of the sintered body are exposed on the entire surface. . On the other hand, in the fragrance generating product described in Patent Document 2, since plating is performed when the fragrance-generating product is manufactured, there is a problem that manufacturing takes a lot of time and manufacturing costs increase. Furthermore, when plating the sintered body, the plating solution containing acid or alkali penetrates into the sintered body, and it takes a lot of trouble to remove the plating solution soaked in the sintered body from the sintered body. In addition, it is impossible to completely remove the plating solution from the sintered body.

  Furthermore, in the fragrance-generating product described in Patent Document 3, since a sealed region is formed by blasting, press-compressing, melting, and further applying an adhesive, a metallic glossy surface cannot be obtained, and the appearance is unsatisfactory. There is a problem that is low. Further, in blasting, press compression, and melting, it is difficult to close the voids of the sintered body, and thus there is a problem that it is not possible to reliably prevent the fragrance from leaking.

  In view of the above problems, an object of the present invention is to provide an accessory, a sintered part for manufacturing an accessory, and a method for manufacturing the accessory that can obtain a metallic glossy surface even when a sintered body is used. is there.

  Moreover, the subject of this invention is providing the structure which can prevent the unnecessary divergence of the fragrance | flavor from a sintered compact, when an accessory is comprised as a fragrance generation goods.

  Furthermore, the subject of this invention is providing the structure which can employ | adopt adhesive fixation, even when fixing a sintered compact to a seat.

  Furthermore, the subject of this invention is providing the structure which can form a metallic glossy surface efficiently even if it is a plate-shaped sintered compact.

  In order to solve the above problems, in the present invention, in an accessory having a sintered body having a large number of voids between metal powders, at least a part of the surface of the sintered body is on the surface of the sintered body. A sealing region in which the gap is closed by a polishing process on the surface to form a metallic gloss surface is formed. In the present invention, the “sealed region” is meant to include both a state where the void is completely closed and a state where the surface opening rate is extremely low. In addition, the “accessory” in the present invention is a so-called “small item”, and includes an item attached to a body, a key holder, a mobile phone, etc., as well as an item installed in a desk or a car.

  In the present invention, since the sealed region is formed by closing the gap by polishing the sintered body, unlike the case where the sealed region is formed by blasting, press compression, melting, adhesive application, etc., The region has a metallic gloss surface equivalent to that of the bulk, and has a good appearance. Moreover, since it is a sintered compact, an accessory can be manufactured lightweight and cheaply. Furthermore, since the sealed region is formed by polishing the surface of the sintered body, the working efficiency is high unlike the case where the gap is closed by plating. In addition, unlike plating, a plating solution containing an acid or an alkali does not penetrate into the sintered body, so that it is not necessary to take much trouble to remove the plating solution from the sintered body. Furthermore, unlike plating, there is an advantage that there is no restriction on the metal material constituting the sintered body. Moreover, since it is a sintered body, it is possible to use as a fragrance-generating product by forming a sealed area and an open area on the surface of the sintered body and impregnating the sintered body with the fragrance from the open area. .

  In addition, when used as an aroma generating product, the sealed area formed in the accessory of the present invention is an area clogged by polishing, so that the void is completely closed or the surface Since the porosity is very low, no or no evaporation of the fragrance occurs from the sealed area. Therefore, a fragrance can be generated over a long period of time.

  Furthermore, when using as accessories, etc., when fixing the accessory of the present invention to the seat, since the adhesive does not permeate from the sealed area, when fixing the sintered body to the seat, the sealed area and The seat body can be securely fixed with an adhesive.

  In the present invention, a configuration in which the entire surface of the sintered body is the sealed region can be employed.

  In the present invention, it is possible to adopt a configuration in which the sealing region and the opening region where the gap is exposed are formed on the surface of the sintered body. If comprised in this way, if the design of the layout of a sealing area | region and an opening area | region etc. is devised, there also exists an advantage that the decoration effect of a sealing area | region and an opening area | region is exhibited. Further, when a sealed region and an open region are formed on the surface of the sintered body and the sintered body is impregnated with the fragrance from the open region, it can be used as an aroma generating product.

  In the present invention, the aperture region is preferably a recess. If comprised in this way, since a recessed part exhibits the decorative effect, it can improve the designability. When used as a fragrance-generating product, the scented material can be impregnated into the sintered body simply by dropping the scented agent in the recess, and if the aperture region is a recess, the aperture region becomes wet with the fragrance. Even if it is in a wet state, the fragrance does not touch the hand or skin directly, so there is an advantage that it is easy to use.

  In the present invention, the sintered body is plate-shaped, and the concave portion constituting the aperture region is formed on at least one of the front surface and the back surface of the sintered body, and the concave portion is surrounded by the surface. Are all surrounded by a contoured convex part constituted by the sealing region, and are divided into a plurality of parts by the convex part. When the sintered body is plate-shaped, distortion is likely to occur due to the accuracy of the molding process. Therefore, when the surface is polished to a flat surface, it is preferable to shape it by a press before that. If the concave portion is formed over a wide area on the surface of the film, it will be bent when pressed by a roller. However, if the concave portion is divided, such bending can be prevented.

  The accessory according to the present invention can be used as an aroma generating product by impregnating the sintered body with a fragrance. Further, the sintered body can be fixed to a seat and used as an accessory. In the latter case, it is preferable that the sintered body is fixed to the seat body with an adhesive in the sealing region. Since the adhesive does not permeate from the sealed area, when the sintered body is fixed to the seat, the sealed area and the seat can be securely fixed by the adhesive.

  In the present invention, the sintered body is, for example, a sintered body of silver such as sterling silver, stainless steel such as SUS304, or titanium. Further, a sintered body of metal powder such as brass, aluminum bronze, or white can be used.

  In the present invention, the sintered body is preferably formed by sintering metal powder having a particle size of 100 to 200 mesh so that the porosity is in the range of 5 to 30% by volume. When such conditions are set, the glossy metal surface can be reliably formed by polishing and the gap can be reliably closed. Moreover, there is an advantage that the appearance of the aperture region is good when the aperture region is formed.

  In the present invention, a sintered part for manufacturing an accessory for manufacturing an accessory in which a sintered body having a large number of voids between metal powders is impregnated with a fragrance, the surface of the sintered body being The open area where the voids are exposed and the closed area where the voids are closed by polishing the surface of the sintered body to form a metallic glossy surface. If such a sintered part is prepared, it can be impregnated with any fragrance according to the demands of the person using it. Moreover, if such a sintered part is sold, the person who purchased it can impregnate a favorite fragrance.

  In the present invention, there is provided a sintered part for manufacturing an accessory for manufacturing an accessory in which a fragrance is impregnated in a sintered body having a large number of voids between metal powders, and the entire surface of the sintered body is The pores are closed by polishing the surface of the sintered body to form a sealed region having a metallic glossy surface. If such a sintered part is prepared, it can be impregnated with a fragrance after the sealing area is cut into an arbitrary pattern to form the opening area according to the request of the person who purchases the sintered part. .

  According to the present invention, there is provided a method for manufacturing an accessory having a sintered body having a large number of voids between metal powders, the metal powder being formed into a green compact of a predetermined shape, and the green compact. And sintering the at least part of the surface of the sintered body so that the voids are blocked on the surface of the sintered body. And a crushing step for forming a sealed region having a metallic gloss surface.

  In the present invention, in the crushing step, for example, the entire surface of the sintered body is subjected to polishing to make the entire surface of the sintered body the sealing region. In this case, after the crushing step, a hole region forming step may be performed in which the hole region is partially cut to form a hole region where the void is exposed. In the hole area forming step, the surface of the sintered body may be shaved so that the hole area becomes a recess. In the case where the concave portion is formed by molding the metal powder, the concave portion cannot be formed deeply due to the removal from the mold. However, with such a method, the concave portion can be formed deeply.

  In the present invention, in the crushing step, a part of the surface of the sintered body is subjected to a polishing process so that a part of the sintered body is used as the sealing region, and the rest is used as the opening region where the void is exposed. Good. In this case, in the forming step, when forming the green compact, a configuration in which a recess is formed in a region corresponding to the hole region, or after the sintering step and before the crushing step, the hole is formed. It is preferable to perform a concave portion forming step of forming a concave portion by cutting an area corresponding to the area.

  In the present invention, when the sintered body is plate-shaped, the surface to be subjected to the flat polishing process is flattened by pressing the sintered body before performing the flat polishing process in the crushing step. It is preferable to perform the press shaping process. In the case where the sintered body is plate-shaped, distortion is likely to occur due to the accuracy of the molding process. Therefore, it is preferable to shape the surface by pressing before surface polishing.

  In the present invention, the sintered body is plate-shaped, and when the area corresponding to the open area is formed as a recess in at least one of the front and back surfaces of the sintered body, the open area is The concave portion to be configured is surrounded by isoconvex convex portions that are all constituted by the sealing region in at least one of the front surface and the rear surface of the sintered body, and is divided into a plurality by the convex portions. It is preferable to form in the state which was made. If comprised in this way, in the said crushing process, the said sealing | blocking area | region will be formed in the surface in which the said recessed part of the said sintered compact was formed by the surface grinding | polishing process in the state which hold | maintained the said several sintered compact to the holder. At the same time, even when a press shaping process is performed to flatten the surface to be subjected to the flat polishing process by pressing the sintered body before performing the flat polishing process, the deformation of the sintered body is prevented. be able to. That is, when the sintered body is plate-shaped, distortion is likely to occur with the accuracy of the molding process. Therefore, it is preferable to shape the surface with a press before polishing the surface. If the concave portion is formed over a wide area on one surface, it will be bent when pressed by a roller. However, if the concave portion is divided, such bending can be prevented.

  When the accessory according to the present invention is configured as a fragrance generating product, a fragrance impregnation step of impregnating the sintered body with the fragrance from the aperture region is performed. In this invention, when fixing the said sintered compact to a seat body, it is preferable to perform the fixing process which fixes to a seat body with an adhesive agent in the said sealing | blocking area | region.

  In the present invention, since the sealed region is formed by closing the voids by polishing the sintered body, the sealed region has a metallic gloss surface equivalent to that of the bulk and has a good appearance. Moreover, since it is a sintered compact, an accessory can be manufactured lightweight and cheaply. Furthermore, since the sealing region is formed by polishing the surface of the sintered body, the sealing region can be efficiently formed, and the manufacturing cost can be reduced. Further, unlike plating, there is an advantage that there is no restriction on the metal material constituting the sintered body. Moreover, since it is a sintered compact, if a sealing area | region and an open area | region are formed in the surface of a sintered compact, a fragrance | flavor is impregnated into a sintered compact from an open area | region, and it can use as an aroma generating product. In this case, since the sealing region formed in the accessory of the present invention is a region that has been crushed by polishing, the gap is completely closed or the surface porosity is extremely low. As it is, no or no evaporation of the fragrance occurs from the sealed area. Therefore, a fragrance can be generated over a long period of time. Furthermore, when using as accessories, etc., when fixing the accessory of the present invention to the seat, since the adhesive does not permeate from the sealed area, when fixing the sintered body to the seat, the sealed area and The seat body can be securely fixed with an adhesive.

It is explanatory drawing which shows typically another fragrance | flavor generation goods.

  1 (a) and 1 (b), the fragrance generating product 1 of this embodiment is a jewelry such as a pendant head, a ring, a bracelet, or a brooch, a miscellaneous product such as a mobile phone strap, an indoor or in-car figurine, etc. The sintered body 2 having a large number of voids 26 is impregnated with the fragrance 3. Here, on the surface of the sintered body 2, an open region 21 where the voids 26 are exposed and a sealed region 22 where the voids 26 are closed by polishing on the surface of the sintered body 2 are configured. In this embodiment, a part of the upper surface, the side surface, and the lower surface of the sintered body 2 are the sealed region 22. In the sealing region 22, the void 26 is completely closed or the surface opening rate is extremely low. Moreover, the sealing area | region 22 is in the state crushed by grinding | polishing, and is a metal glossy surface. For this reason, the aroma generating product 1 has a good appearance.

  In the fragrance generating product 1 configured as described above, the sealed region 22 is formed by polishing the sintered body 2 so as to close the gap and form the sealed region 22. Unlike the case where it forms, the sealing area | region 22 is equipped with the metallic luster surface equivalent to a bulk, and is good-looking. Further, in this embodiment, since the hole region 21 where the void 26 is exposed is formed on the upper surface of the sintered body 2, the scented body 2 can be impregnated with the fragrance 3 from the hole region 21, And a fragrance can be discharge | released outside from the aperture region 21. FIG. In addition, a part of the upper surface, the side surface, and the lower surface of the sintered body 2 are configured as a sealed region 22 in which the voids 26 are closed, and the fragrance 3 is not evaporated at all from the sealed region 22. It does not occur or very little evaporation occurs. Therefore, a fragrance can be generated over a long period of time. Moreover, since the sealing area | region 22 was performed by grinding | polishing processes, such as mirror polishing with respect to each surface of the sintered compact 2, work efficiency is high unlike the case where a space | gap is plugged up. Further, unlike plating, a plating solution containing an acid, an alkali, or the like does not penetrate into the sintered body 2, so that it is not necessary to take much trouble to remove the plating solution from the sintered body 2. Therefore, the aroma generating product 1 can be manufactured at low cost. Further, unlike plating, there is an advantage that there is no restriction on the metal material constituting the sintered body 2. Furthermore, if the design is devised about the opening area | region 21, there also exists an advantage that a decorative effect is exhibited.

  Further, the evaporation amount of the fragrance 3 can be adjusted by the area, shape, and number of the aperture regions 21. Thereby, the time of the scent in the fragrance generating product 1 and the strength of the scent emitted can be adjusted.

  Furthermore, if a plurality of fragrance generating products 1 impregnated with different types of fragrances 3 are prepared, a fragrance adapted to TPO can be generated depending on which one is used. In particular, if the fragrance generating product 1 to which the present invention is applied is used as a bracelet or the like, it is possible to enjoy a scent without directly attaching perfume or the like to the skin or clothes.

  Here, in the production of the sintered body 2, the metal powder having a particle size of 80 mesh or less, preferably 100 to 200 mesh, has a porosity of 5 to 50% by volume, preferably 5 to 5% by volume. It is preferable to sinter so that it may become the range of 30 volume%, More preferably, it is 15-30 volume%. If it sets to such conditions, a glossy finishing surface (mirror surface) will be carried out when grinding | polishing processing is performed. can get. In addition, the glossy metal surface can be reliably formed by polishing and the gap can be reliably closed. Moreover, there exists an advantage that the appearance of the opening area | region 21 is good. Furthermore, the capillary force of the voids can be increased in the sintered body 2, and the fragrance 3 is preferably impregnated.

  Moreover, in the fragrance generating product 1 shown in FIG. 1 (c), the aperture region 21 is a recess 25. The depth of the recess 25 is, for example, 0.05 to 0.5 mm. Since the other configuration is the same as that shown in FIG. 1 (a), common portions are denoted by the same reference numerals and description thereof is omitted. Since the hole region 21 is a recess 25, the scented material 3 is impregnated with the scented body 2 simply by dropping the fragrance 3 in the recess 25. Moreover, since the opening area | region 21 is the recessed part 25, even if the opening area | region 21 is wet with the fragrance | flavor 3, since the fragrance | flavor 3 does not touch a hand or skin directly, it is convenient. There is an advantage.
