The present invention relates to a method for producing a decorative seal.

Generally, although the seal is manufactured from materials, such as a molar tooth and a horn of a wood or an animal, in recent years, the seal made from synthetic resins is also manufactured. The seal made of synthetic resin is generally formed after forming a seal base material through a molding process of filling a synthetic resin raw material such as a liquid epoxy resin into a cylindrical mold. Although it is produced by carving a seal portion at one end of the seal base material, it can be seen that a decoration is provided inside the seal base material. As a manufacturing method of the seal which provided the decoration inside, patent document 1 has the process of inject | pouring a synthetic resin of the quantity which is not filled in a transparent cylinder, and the inner peripheral surface of the cylinder in which synthetic resin was injected ( A method of producing a decorative seal is disclosed through a step of inserting a decorative pattern imparting sheet body into a cylinder along a process of injecting a synthetic resin until the cylinder into which the decorative pattern imparting sheet body is inserted is filled. .

By the way, the manufacturing method of the decorative seal disclosed by patent document 1 had a problem that a manufacturing process was complicated because the synthetic resin must be divided into two stages and filled inside a cylinder. Moreover, when inserting a planar pattern provision sheet | seat body into a cylinder inside, there existed a problem that the said sheet body was inclined or bent, and it is difficult to arrange | position it in a desired position.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a method of manufacturing a decorative seal which can easily form a desired decorative pattern.

The above object of the present invention is a method of manufacturing a decorative seal, the decorative seal comprising a step of inserting a decorative holder with an inner decoration inside the transparent cylinder, and a step of filling the cylinder with a synthetic resin to cure it. It is achieved by the manufacturing method of.

In the manufacturing method of this decorative seal, it is preferable that the said cylinder body has the bottom plate in which the recessed part in which the front-end | tip part of the said decoration holding body was formed was provided in the edge part of one side.

Moreover, it is preferable that the said decoration holding body includes the holding stand provided with the outer peripheral surface which contacts the inner peripheral surface of the said cylinder at the one end at the time of insertion into the inside of the said main body.

Moreover, it is preferable that the outer ornament is integrally formed in the edge part of the said ornament holding body, and the said ornament holding body is inserted in the said cylinder so that the outer ornament may protrude from a cylinder.

Moreover, it is preferable that the said synthetic resin is a urethane resin, and includes the process of forming a printing surface in the exposed surface of the said urethane resin.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described with reference to attached drawing. 1 is a process chart showing a method of manufacturing a decorative seal.

First, as shown in Fig. 1A, the decorative holder 20 having the inner ornament 15 attached thereto is inserted into the cylinder 10. As shown in Figs.

The cylinder 10 is a cylinder formed of transparent acrylic resin, and has the bottom plate 11 at one end part.

The decorative holder 20 includes a solid cylindrical rod-shaped body 21 and a holder 22. In addition, the rod-shaped body 21 and the holder 22 are formed of acrylic resin, and are transparent bodies. The holder 22 is disk-shaped, and is formed so that the diameter dimension may become substantially the same as the inner diameter dimension of the cylinder 10. In addition, when the decorative holder 20 is inserted into the cylinder 10 and mounted on the bottom plate 11, the decorative holder 20 is formed so that the height of the end portion is almost the same as the height of the cylinder 10.

The internal ornament 15 is, for example, a sheet, a seal, or the like, which describes characters and patterns such as beads, jewelry, glass pieces, ores, star sand, photographs, and names. ), A film, paper, and the like, and are attached to the decorative holder 20 by an adhesive or the like.

Subsequently, as shown in Fig. 1B, an epoxy resin, a urethane resin, an acrylic resin, or a polyethylene resin is provided in the space between the decorative holder 20 and the cylinder 10 to which the decorative pattern is added. The synthetic resin 25 is filled. In particular, when an epoxy resin is used as the synthetic resin 25, it has a feature that the volume shrinkage at the time of curing is small and the dimensional stability is high, so the workability of molding is excellent. The filling step of the synthetic resin 25 may be performed using a vacuum degassing machine in order to prevent air bubbles from remaining inside the cylinder 10. In addition, in order to improve the weather resistance of the synthetic resin, the synthetic resin 25 may be filled after inserting the ultraviolet ray blocking film to impart the inner peripheral surface of the cylinder 10.

Thereafter, heat treatment or the like is performed on the filled liquid synthetic resin 25 to cure the synthetic resin 25 to produce a seal substrate 30. As the heat treatment means, for example, a cracking furnace, a dryer, or the like can be used.

Then, as shown in Fig. 1C, by attaching the printing portion 32 on which the engraving process such as letters or figures, such as a name, etc. is applied to the end 31 of the seal substrate 30 with an adhesive or the like. The decorative seal is completed.

According to the manufacturing method of the decorative seal of this embodiment, like the manufacturing method of the decorative seal disclosed by the said patent document 1, it is not necessary to divide the synthetic resin 25 into two steps and to fill it into the cylinder 10, Since the filling of the synthetic resin 25 is completed by one filling operation, the complexity in the manufacturing process of the decorative seal can be eliminated, and the manufacture of the decorative seal can be facilitated.

Moreover, since the outer diameter dimension of the holding stand 22 is substantially the same as the inner diameter dimension of the cylinder 10, the outer peripheral surface of the holding stand 22 contacts the inner peripheral surface of the cylinder 10, and the decorative holding body 20 Since is mounted on the bottom plate 11 of the cylinder 10, the decorative holder 20 can be maintained in a constant state relative to the cylinder 10. Therefore, a desired decorative pattern can be easily formed in a desired position inside the seal.

As mentioned above, although 1st Embodiment of this invention was described, the specific aspect of this invention is not limited to the said embodiment.

For example, in the above embodiment, as shown in Fig. 1A, the decorative holder 20 includes a holder 22, but instead of providing the holder 22, As shown in FIG. 2, the recessed part 12 may be provided in the center of the upper surface of the bottom plate 11 of the cylinder 10, and the rod-shaped body 21 may be inserted. By setting it as such a structure, since the front-end | tip part of the rod-shaped body 21 with the inner ornament 15 can be hold | maintained in a recessed part, the number of parts of the decorative holding body 20 can be reduced, and manufacture of a decorative seal Becomes easy. In addition, although the recessed part 12 is preferably formed in the center of the upper surface of the bottom plate 11, the formation position is not specifically limited, It can be arbitrary positions.

In addition, as shown in FIG. 3, the decorative material 20 uses the wire 23 which can be plastically deformed, such as a wire, for example, and the inner decoration 15 is attached to the wire 23. After the decoration is carried out by attaching the mold, the shape may be formed into a spiral shape or the like so as to contact the inner circumferential surface of the cylinder 10 and inserted into the cylinder 10.

As the decorative holder 20, instead of using the rod-shaped body 21, a curved body may be used so that a plurality of portions of the curved body come into contact with the inner circumferential surface of the cylinder 10.

In addition, as shown in Fig. 4, an outer ornament 16 is formed at the end of the decorative holder 20 so as to be integral with the holder 20, and the outer ornament 16 protrudes from the cylinder 10. The decorative holder 20 may be inserted into the cylinder 10 so as to manufacture a decorative seal. According to this manufacturing method, a seal capable of effectively preventing the outer ornament 16 from falling off can be produced as compared with the case where the outer ornament 16 is attached to the seal end portion by an adhesive or the like.

In addition, in this embodiment, although the rod-shaped body 21 of the decorative holding body 20 is a solid body, it forms so that it may become a hollow body as shown in FIG. 5, and the hollow part 24 has a bead You may insert jewelry, etc. Moreover, you may inject into the said hollow part 24 several types of liquid from which the density colored by the different color differs.

In addition, in this embodiment, as shown in FIG.1 (c), although the printing part 32 separate from the seal base material 30 is attached to the edge part 31 of a seal base material, By using the synthetic resin 25 excellent in workability as the internal synthetic resin 25 for filling, the printing process may be performed on the end face 31 of the seal substrate 30 directly. Thereby, since it is not necessary to manufacture the printing part 32 separate from the seal base material 30, manufacture of a decorative seal becomes easy. As synthetic resin 25 excellent in such workability, a urethane resin etc. are mentioned, for example. Moreover, since urethane resin has the characteristic that it is excellent in elasticity, the seal manufactured by filling a urethane resin in the inside of the cylinder 10 will have elasticity by itself. Therefore, even if the sheet is placed directly on a desk or the like with a hard surface without being stamped with the elastic sheet at the bottom of the sheet to be stamped, it is possible to leave a clear print mark.

In addition, although the cylinder 10 is a cylindrical shape, the cross-sectional shape of the cylinder 10 can employ | adopt various shapes, such as an ellipse shape, a triangular shape, or a square shape. In addition, although the cylinder 10 is formed of acrylic resin, other synthetic resin, for example, ABS resin, polyethylene, a polypropylene, etc. may be sufficient. In addition, the cylinder 10 may be a transparent body, and may be colorless transparent or colored transparent.

In addition, although the decorative holding body 20 is a transparent body, you may form the colored decorative holding body 20 by mixing the pigment which has each color in these formation steps. In addition, although the decorative holder 20 is formed of acrylic resin, other materials such as synthetic resin, glass, metal, wood, and the like may be used. The decorative holder 20 includes a cylindrical rod-shaped body 21, but may be, for example, a rod-shaped body 21 such as a delta, a square column, a cone, a triangular pyramid, a spiral, or a wave shape. In particular, the shape is not limited.

In addition, although the decoration is provided by attaching the inner ornament 15 to the decorative holding body 20 with an adhesive or the like, instead of attaching the inner decorative material 15, air blushing or the like is applied to the surface of the decorative holding body 20. You can install a decoration by drawing a pattern. Moreover, you may provide a pattern by transferring a pattern to the surface of the decorative holding body 20 with a transfer paper.

In addition, in the said embodiment, although the structure which attaches the internal ornament 15 to the rod-shaped body 21 is employ | adopted, if it is the structure which can attach the internal ornament 15, you may use other than the rod-shaped body 21. . For example, instead of using the rod-shaped body 21, a structure in which miniatures such as animals and plants, buildings and the like, jewelry, glass pieces, beads and the like are connected by an adhesive may be used. As described above, even when the decorative holder 20 is formed by using miniatures such as animals and plants instead of the rod-shaped body 15, the holder 22 is attached to one end of the miniature or the like to form a miniature or the like. The decorative holder 20 can be maintained in a constant state relative to the cylinder 10. 6, the decorative seal 1 which comprised the decorative holding body 20 using the snake miniature instead of the rod-shaped body 15 is shown.

In addition, instead of providing the holding table 22, a recess 12 is formed in the bottom plate 11 of the cylinder 10, and a tip such as a miniature or the like is inserted in the recess 12, thereby miniatures and the like. The decorative holder 20 configured as described above can be maintained in a constant state with respect to the cylinder 10.

In addition, in the said embodiment, although the structure which attaches the printing part 32 separate from the said seal base material 30 to the edge part 31 of the seal base material 30 is employ | adopted, As this printing part 32, it is an example. For example, the permeability printing part 32 as shown in the schematic sectional drawing of FIG. 7 is employ | adopted, and the structure attached to the edge part 31 of the seal base material 30 can also be employ | adopted. This permeable printing portion 32 is composed of a printing portion 41 formed of a porous body, an ink containing portion 42, a spring member 43, a cover 44, and an outer cylinder 45, and includes an ink containing portion ( The ink 42a accumulated in 42 is penetrated into the printing surface 41b from the printing surface rear surface 41a and supplied so that the ink can be stamped without being buried on the printing surface 41b each time a seal is taken. have.

Further, as shown in Fig. 8, the decorative seal 1 is formed by forming the decorative seal 1 thin and long, and at the same time forming a space 50 for accommodating the refill (writing mechanism core) of a ballpoint pen and the like. May be used as a stand for a writing instrument with a seal.

According to this invention, the manufacturing method of the decorative seal which can form a desired decorative shape easily can be provided.
