  Conventionally, for example, a seal is generally manufactured by engraving a seal on the end face of a pillar-shaped seal substrate made of hard wood or a dense material such as animal horns and bones. It has been a long time since a stamp base material is made of a synthetic resin without using such a natural product as a raw material from the viewpoint and high cost.

  A seal substrate made of synthetic resin is usually manufactured by a so-called molding process by injecting a predetermined synthetic resin raw material in a molten state into a cylindrical mold, but the obtained seal substrate is simply formed in a columnar shape. It is only a present and it is extremely killing.

  In order to eliminate such inconveniences, it is possible to manufacture a seal substrate having a striped pattern by injecting two types of synthetic resins of different colors into a mold while mixing them gently, or to produce a fine metal piece in a transparent molten resin. In some cases, the metal pieces are scattered in the seal substrate by mixing the metal pieces.

  However, the seal substrate has a striped pattern on its peripheral surface, or even if a metal piece is scattered inside, it is extremely simple as a picture, and all are in the same state, so they can claim originality. It will not be interesting.

  FIG. 1 is a diagram showing a first embodiment of a seal substrate according to the present invention, in which (a) is a perspective view, (b) is a sectional view taken along line AA, and (c) is a sectional view taken along line BB. It is. As shown in FIG. 1, the seal substrate 10 of the first embodiment includes a transparent bottomed cylindrical body 20 and a patterned sheet body 30 having a predetermined pattern laminated on the inner peripheral surface of the cylindrical body 20. And a core material 40 formed by injecting a synthetic resin material in a flowing state into the inside of the patterned sheet body 30 and then performing a solidifying treatment.

  In the present embodiment, the cylindrical body 20 has a cylindrical shape, but is not limited to the cylindrical shape, and may have various shapes such as an elliptical shape, a square shape, or a polygonal shape in a sectional view. Can be adopted. In the present embodiment, the cylindrical body 20 is formed of an acrylic synthetic resin (acrylic resin). Acrylic resin is used for the cylindrical body 20 because acrylic resin (particularly polymethyl methacrylate (PMMA)) has high transparency, and the picture of the sheet 30 with the picture inside the cylindrical body 20 can be clearly seen from the outside. Because you get.

  Incidentally, the present invention is not limited to the cylindrical body 20 being made of an acrylic resin, and may be another transparent synthetic resin (for example, polyethylene, polypropylene, polyvinyl chloride, polyamide, or the like), It may be a transparent glass.

  In the present embodiment, the sheet body 30 with a picture uses Japanese paper as a sheet body. A predetermined pattern is printed on the surface of the sheet body made of Japanese paper to form a sheet body 30 with a pattern.

  The reason for using Japanese paper as the sheet body is as follows. That is, when the synthetic resin in a fluidized state is injected into the cylindrical body 20 loaded with the patterned sheet body 30, the synthetic resin penetrates into the pores of the coarse Japanese paper, and the Japanese paper removes the pattern portion. Except for this, the ground portion becomes translucent, and a fiber pattern peculiar to Japanese paper appears, so that the appearance of the seal substrate 10 becomes extremely rich in texture.

  However, in the present invention, the sheet body is not limited to Japanese paper, but may be ordinary Western paper or a film made of synthetic resin. In addition, the pattern of the sheet 30 with a pattern includes a pattern, a character, a figure, a symbol, or a combination thereof, as well as a photograph or a handwritten drawing.

  The vertical dimension of the picture-attached sheet body 30 is set to be slightly shorter than the inner dimension of the cylindrical body 20 in the axial direction, and the horizontal dimension is set to be substantially equal to the inner peripheral length of the cylindrical body 20. . Therefore, the sheet body 30 with the picture is wound into a tubular shape in the lateral direction, and then inserted into the tubular body 20 so as to reach the inner part in a sliding contact state, so that the inner peripheral portion of the tubular body 20 on the opening side is opened. In this state, a portion where the sheet 30 with the picture does not exist is formed.

  The core member 40 is formed of an epoxy resin in the present embodiment. The reason that the epoxy resin is adopted as the core material 40 is as follows. That is, since the epoxy resin is solidified by mixing a predetermined hardener into a liquid state before solidification and performing a heating treatment for a predetermined time, the epoxy resin is easy to handle and has excellent workability in molding. This is because the epoxy resin does not shrink during curing and has extremely good dimensional stability. Further, the epoxy resin is excellent in workability such as engraving and is excellent as a material of the core material 40 of the seal substrate 10. However, the present invention is not limited to the case where the core material 40 is made of an epoxy resin, and another synthetic resin having high dimensional stability may be employed instead of the epoxy resin.

  The epoxy resin mixed with such a curing agent is injected into the cylindrical body 20 in which the sheet 30 with the picture is inserted, and then subjected to a solidification treatment by heating, whereby the seal substrate 10 as shown in FIG. 1 is obtained. . The seal substrate 10 thus obtained constitutes a handle portion (a portion to be sandwiched). Then, a seal portion 15 having an engraved surface is detachably (exchangeably) attached to the tip of the seal substrate 10 to complete a stamp-type seal 61 that does not require vermilion (see FIG. 2). The stamp type that does not require vermilion refers to a stamp type in which a portion corresponding to vermilion is provided in the seal portion 15 and vermilion does not need to be used separately.

  FIG. 3 is a process chart for explaining a method for manufacturing the seal substrate 10 (seal) of the first embodiment. As shown in this figure, the seal substrate 10 of the first embodiment has a first resin injection step P1, a sheet insertion step P2, a second resin injection step P3, a resin solidification step P4, and a finish. It is manufactured through the process P5.

  The primary resin injection step P1 is a step of injecting the liquid epoxy resin X mixed with the curing agent into the cylindrical body 20. In the primary resin injection step P1, the epoxy resin X is injected into the cylinder 20 in an amount less than the expiration. Incidentally, in the present embodiment, the epoxy resin X is injected into the cylindrical body 20 until the inner volume of the cylindrical body 20 is filled with 40% to 80%, preferably about 70%. The reason for this is to make it possible to easily perform the operation of inserting the sheet with picture 30 into the cylindrical body 20 in the next sheet body inserting step P2.

  That is, if the epoxy resin X is previously injected into the cylindrical body 20 until it becomes full, the diameter of the patterned sheet body 30 when the cylindrical patterned sheet body 30 is inserted into the cylindrical body 20 is increased. The operation of inserting the sheet 30 with the picture into the cylinder 20 becomes difficult, for example, the operation becomes difficult or the epoxy resin X overflows from the cylinder 20. However, such an inconvenience is avoided. Therefore, the operation of injecting the epoxy resin X is stopped before it becomes full.

  In addition, an infinite number of scratches are previously applied to the inner peripheral surface of the cylindrical body 20 used in the primary resin injection process P1 using a predetermined tool. By doing so, the injected epoxy resin X enters into numerous scratches, and the adhesion of the solidified epoxy resin X to the inner peripheral surface of the cylindrical body 20 via the patterned sheet body 30 is improved. .

  In the sheet body inserting step P2, the sheet body 30 with the picture that has been rounded into a cylindrical shape is inserted into the cylindrical body 20 into which the epoxy resin X has been injected until just before the first resin injection step P1 becomes full. It is a process. In the sheet body inserting step P2, the sheet body 30 with the picture, which has been rounded so as to have an outer diameter dimension substantially matching the inner diameter dimension of the cylindrical body 20, is in close contact with the inner peripheral surface of the cylindrical body 20. It is gently inserted into the cylindrical body 20. By doing so, the sheet member 30 with the design comes into contact with the inner peripheral surface of the cylindrical body 20 in which approximately 70% of the internal volume is filled with the epoxy resin X.

  In addition, countless scratches are provided on the inner peripheral surface of the cylindrical body 20, and the epoxy resin X enters the scratches, so that the rounded sheet body 30 with a picture is placed in the cylindrical body 20. At the time of insertion, the lower end edge portion of the picture sheet body 30 does not expel the epoxy resin X adhering to the inner peripheral surface of the tube body 20. And an epoxy resin can be left between them. Therefore, at the time when the patterned sheet body 30 has been inserted into the cylindrical body 20, the epoxy resin X is no longer present between the outer peripheral surface of the patterned sheet body 30 and the inner peripheral surface of the cylindrical body 20 and the There is no inconvenience such as a decrease in adhesion.

  The secondary resin injecting step P3 is a step in which the epoxy resin X is further added into the cylindrical body 20 into which the sheet with picture 30 has been inserted in the sheet inserting step P2 until the epoxy resin X has expired. By passing through the secondary resin injection step P3, all of the materials for forming the seal substrate 10 are loaded in the cylindrical body 20.

  In the resin solidification step P4, the cylinder 20 in which the epoxy resin X has been injected is charged into a predetermined soaking furnace 50 and heat-treated until it is completed in the previous secondary resin injection step P3. This is a step for solidifying the epoxy resin X. In the present embodiment, the temperature inside the soaking furnace 50 is controlled to 40 ° C. to 90 ° C. The cylindrical body 20 having the full amount of the epoxy resin X is loaded into the soaking furnace 50 and left standing for 1 to 2 hours. By doing so, the epoxy resin X in the cylindrical body 20 is hardened and solidified, and the original body 60 of the seal substrate 10 is formed.

  In the next finishing step P5, the original body 60 thus obtained is subjected to surface polishing such as so-called water polishing in which high-pressure water is injected or so-called buff polishing in which polishing is performed by pressing a peripheral surface against a rotating buff. The processing is performed to obtain the seal substrate 10 as a product. Then, the seal portion 15 is attached to the tip of the seal substrate 10 to complete the seal 61.

  According to the seal of the first embodiment manufactured in this manner, even if the surface of the seal is rubbed by repeated use, the pattern is applied to the sheet 30 with the pattern that is in close contact with the inner peripheral surface of the cylindrical body 20. Therefore, there is no inconvenience such as rubbing and peeling off like a handwritten design on the outer peripheral surface of a conventional seal substrate, and a beautiful state can be maintained forever.

  In addition, it is possible to adopt not only a simple pattern but also a photograph or a picture as a picture of the picture-attached sheet body 30, and the seal substrate 10 becomes extremely specific. In particular, if Japanese paper is adopted as the sheet body of the sheet body 30 with a picture, a unique texture of Japanese paper is brought out to the seal substrate 10, and the seal substrate 10 can be made to have a high-grade feel.

  Furthermore, if the photographic paper taken by an instant photograph commonly called Purikura is adopted as the picture-attached sheet body 30, the seal substrate 10 also becomes an original souvenir of the owner's individual, and the tasteless and dry seal is extremely reduced. It can be a thing that can evoke an entertaining attachment.

  In addition, the manufacturing method of the seal substrate 10 is easy to manufacture and suitable for mass production because there is no complicated process such as engraving the peripheral surface of the cylindrical body 20 or handwriting a design. Cost can be reduced.

  FIG. 4 is a diagram showing a second embodiment of a seal substrate according to the present invention, wherein (a) is a perspective view, (b) is a cross-sectional view taken along line CC, and (c) is a cross-sectional view taken along line DD. It is. As shown in FIG. 4, the seal substrate 11 of the second embodiment includes a sheet body 30 with a picture formed by being wound into a cylindrical shape, and a core material 40 injected into the sheet body 30 with a picture. Therefore, the cylindrical body 20 employed in the first embodiment does not exist. As the material of the patterned sheet body 30, the same material as that of the first embodiment can be adopted. However, since the patterned sheet body 30 is directly exposed to the outside, a film made of a synthetic resin is particularly preferable. It is suitable. Obtaining a seal substrate 11 by forming a cylindrical body with the printed surface side of the film coated with a picture by a printing process or the like, for example, and injecting a synthetic resin such as an epoxy resin into the cylindrical body. Can be.

  Specifically, when manufacturing the seal stamp substrate 11, a mold having a cavity having the same concave shape as the three-dimensional shape of the seal stamp substrate 11 is adopted. Then, a cylindrical shaped sheet body 30 with a picture is first loaded into the cavity of the mold, and thereafter, a liquid synthetic resin is injected into the cylindrical shaped sheet body 30 with a picture, and subsequently, a curing process of the synthetic resin is performed. Is performed, the seal substrate 11 can be obtained.

  According to the seal substrate 11 of the second embodiment, the number of parts can be reduced because the cylindrical body 20 in the first embodiment is not used, and the manufacturing cost can be reduced accordingly.

  In the second embodiment, the core material 40 is formed by injecting a synthetic resin in a flowing state into the patterned sheet body 30, but instead of this, first, the core material 40 is manufactured. In addition, the seal substrate 11 may be manufactured by winding the sheet body 30 with a picture around the outer peripheral surface of the core material 40 via, for example, an adhesive. It is the same as described above that the seal portion 15 is detachably (exchangeably) attached to the seal substrate 11.

  FIG. 5 is a view showing a third embodiment of the seal substrate according to the present invention, wherein (a) is a perspective view, (b) is a sectional view taken along line EE, and (c) is a sectional view taken along line FF. It is. As shown in FIG. 5, the seal substrate 12 of this embodiment includes a core material (columnar body) 40 and a print layer 70 formed by printing on the outer peripheral surface of the core material 40. That is, in the third embodiment, the pattern is directly applied to the outer peripheral surface of the core member 40 without laminating the sheet member 30 with the pattern on the outer peripheral surface of the core member 40 as in each of the previous embodiments. .

  The printing layer 70 employs so-called hot printing, in which a heated melt of a colored thermoplastic synthetic resin is printed as ink. The printing layer 70 made of a thermoplastic synthetic resin is formed on the peripheral surface of the core material 40 by such hot printing, whereby the seal substrate 12 is in a state where various patterns are surely applied to the peripheral surface.

  According to the seal substrate 12 of the third embodiment, the printing layer 70 formed on the peripheral surface of the core material 40 by hot printing is printed with the ink made of the thermoplastic synthetic resin melted by heating. Is solidified by cooling and fixed to the outer peripheral surface of the core material 40 without being easily peeled off. Therefore, the printing layer 70 is fixed to the peripheral surface of the core material 40 in an extremely stable state as compared with the case where a pattern is drawn by hand using a paint on the peripheral surface of the core material 40, and repeated use of the seal is required. The inconvenience of peeling off even if rubbed can be avoided. It is to be noted that the seal portion 15 is detachably (exchangeably) attached to the seal substrate 12 in the same manner as described above.

  Further, the cylinder 81a into which the synthetic resin has been injected is inverted, and excess synthetic resin in the cylinder 81a is removed. At this time, the synthetic resin adheres the patterned sheet body 81a to the inner peripheral surface of the cylindrical body 81a, and forms a resin layer on the inner peripheral surface of the patterned sheet body. After removing the excess synthetic resin in the cylindrical body 81a, it is manufactured through a resin solidifying step P4 and a finishing step P5. The lid 82 is manufactured through the same process.

Further, the seal case 80 shown in FIG. 7 may be one in which the case body 81 and the lid 82 are simply molded from synthetic resin.

  In addition, the case of the present invention is not limited to the one for seals, and may be a case for storing objects to be stored other than the seals. In addition to the case, the case can also be adopted as a decorative tool such as a writing implement or a cosmetic. The use is not particularly limited, and any cross-sectional shape can be adopted.

  8 and 9 are a front sectional view and an exploded perspective sectional view showing an embodiment of the seal 100 according to the present invention. In the seal 100 of this embodiment, a joint 22 is projected from a bottom surface 21 of a cylindrical body 20 constituting the seal substrate 10 manufactured by the method described in the first embodiment. It is formed by coupling a base end portion 101a of a cylindrical holder 101 for storing the seal portion 102.

  The coupling portion 22 is integrally formed on the bottom surface 21 of the bottomed cylindrical body 20 so as to protrude annularly. Since the tubular body 20 is formed of a transparent acrylic resin, the joint portion 22 is also formed of a transparent acrylic resin, so that the inside of the joint portion 22 can be visually recognized. As described in the first embodiment, the cylindrical body 20 may adopt an elliptical shape, a triangular shape, a quadrangular shape, a pentagonal shape, a hexagonal shape, or another polygonal shape in addition to a circular shape in a sectional view.

  Here, a hexagonal cylinder 20 will be described as an example. As shown in the drawing, the outer diameter of the cylindrical body 20 on the bottom surface 21 side is slightly larger than the outer diameter on the distal end surface 23 side, and is formed in a tapered shape to facilitate clamping. However, they may be formed to have the same outer diameter over the entire length. In any case, the inner circumference of the cylindrical body 20 is formed in a circular shape having the same inner diameter over the entire length. A sheet 30 with a picture is laminated on the inner peripheral surface of the cylindrical body 20, and a synthetic resin material such as an epoxy resin is injected into the inside of the sheet 30 with the picture, and a solidifying process is performed to form a core material 40. Thereby, the seal substrate 10 is manufactured.

  The outer peripheral surface of the connecting portion 22 integrally formed with the bottom surface 21 of the cylindrical body 20 constituting the seal substrate 10 is hexagonal in cross-sectional view, and the inner peripheral surface is circular. In addition, an L-shaped recessed locking portion 24 is provided at one or more locations on the inner peripheral surface at the distal end edge. A hexagonal ring 103 is fitted to the outside of the joint portion 22 so as to be joined to one end surface of the cylindrical body 20. The ring 103 serves as an accent in design and is not technically essential.

  The proximal end portion 101a of the cylindrical holder 101 is coupled to the coupling portion 22. The holder 101 includes an outer tube 110 formed of a transparent resin, an inner tube 120 formed of a non-transparent resin, and a tube 130 disposed between the outer tube 110 and the inner tube 120. It is composed of The outer cylindrical portion 110 is formed by integrally molding a cylindrical base end portion 111 and a cylindrical distal end portion 112, and the outer diameter of the cylindrical base end portion 111 matches the inner diameter of the coupling portion 22, The fitting part 22 is fitted. Therefore, on the outer periphery of the base end portion 111 of the outer cylindrical portion 110, a projection 113 that enters the locking portion 24 of the coupling portion 22 is provided. Further, the outer cylindrical portion 110 is provided with an annular ridge 114 on the inner periphery of the boundary between the base end portion 111 and the front end portion 112.

  The outer diameter of the distal end portion 112 of the outer cylindrical portion 110 matches the outer diameter of the coupling portion 22, and the outer cylindrical portion 110 and the cylindrical body 20 are formed so as to be integrally continuous. Therefore, the distal end portion 112 of the outer cylindrical portion 110 has a hexagonal outer peripheral surface and a circular inner peripheral surface in a cross-sectional view. Further, the outer cylindrical portion 110 is formed to have a tapered shape on the distal end portion 112 side narrower than the base end portion 111 side, so that a cap 106 described later can be easily fitted, and the design is excellent. However, the distal end portion 112 of the outer cylindrical portion 110 may have the same outer diameter over the entire length.

  On the other hand, the inner cylindrical portion 120 is shorter than the outer cylindrical portion 110, the base end surface 121 is flush with the base end surface 115 of the outer cylindrical portion 110, and the distal end surface 122 is deeper than the distal end surface 116 of the outer cylindrical portion 110. It is formed in such a length. An annular groove 123 into which the protruding ridge 114 of the outer cylinder 110 is fitted is formed at a substantially intermediate portion of the inner cylinder 120. Although the outer cylinder 110 and the inner cylinder 120 are separate bodies, they are elastically deformed and when the ridge 114 of the outer cylinder 110 fits into the groove 123 of the inner cylinder 120, the outer cylinder 110 and the inner cylinder The part 120 cannot be separated again. An enlarged diameter portion 124 is provided on the distal end side of the inner cylindrical portion 120, and the compression coil spring 104 is arranged in a space provided between the enlarged diameter portion 124 and the ridge 114 of the outer cylindrical portion 110. .

  In addition, a tubular pipe 130 is disposed between the enlarged diameter portion 124 of the inner tubular portion 120 and the distal end portion 112 of the outer tubular portion 110. A flange 131 bent inward is formed on the base end side of the tube 130, and the flange 131 collides with the base end surface of the enlarged-diameter portion 124 of the inner cylindrical portion 120, and the tube 130 is moved inside. The flange 131 is pressed against the elastic member, for example, the compression coil spring 104, so that the end of the tubular body 130 is pressed against the distal end surface of the outer cylinder 110. It is made to project slightly beyond 116. The protruding tube 130 can be retracted toward the base end surface 115 of the outer tube 110 against the spring force of the compression coil spring 104.

  Then, the seal portion 102 is attached to the distal end surface 122 of the inner cylindrical portion 120 such that the seal portion 102 is surrounded by such a tubular body 130. By enclosing the seal portion 102 with the tubular body 130, it is possible to prevent the cut face from being exposed, the ink from being carelessly attached, and the cut face from being damaged. The cut face of the seal portion 102 can be exposed when the tube body 130 retreats toward the base end surface 115 of the outer cylinder portion 110.

  For the seal portion 102, for example, a penetration mark that does not require vermilion is adopted. Then, an ink absorber 105 for supplying ink to the seal portion 102 is stored in the inner cylinder 120 adjacent to the seal portion 102. The ink is supplied to the ink absorber 105 from the base end of the inner cylinder 120. To prevent the ink from leaking, the base end of the inner cylinder 120 is closed by a removable plug 140. The plug 140 includes an insertion portion 141 inserted into the inner cylindrical portion 120 and a flange portion 142 formed on an end surface of the insertion portion 141. Since the base end face 121 of the inner cylinder part 120 is flush with the base end face 115 of the outer cylinder part 110, the flange 142 of the plug 140 projects from the base end face 115 of the outer cylinder part 110, and the plug 140 is It can be easily attached to and detached from the inner cylinder 120.

  The holder 101 thus configured is covered and protected by the cap 106. The cap 106 is formed in a bottomed cylindrical shape, and is formed in a hexagonal cross section according to the outer shape of the cylindrical body 20. Since the outer peripheral surface of the coupling portion 22 formed on one end surface of the cylindrical body 20 is formed in a hexagonal shape in cross section, the inner surface of the cap 106 is also formed in a hexagonal shape. The outer portion of the cap 106 is formed of a metal such as aluminum, and the inner portion is formed of a resin. By molding the outer portion with a metal, a sense of quality can be produced, and by molding the inner portion with a resin, the outer portion is elastically deformed, and the connection state with the coupling portion 22 can be improved.

  The seal 100 of the present embodiment configured as described above has a hexagonal seal base 10 and cap 106. The state is maintained. Then, when the cap 106 is removed, the cut face of the seal part 102 is exposed from the end face of the tubular body 130. At this time, since the outer cylindrical portion 110 of the holder 101 is transparent, the tubular body 130, the compression coil spring 104, and the inner cylindrical portion 120 in the outer cylindrical portion 110 look like a pattern, and a decorative effect is exhibited. Further, when the seal substrate 10 is pressed toward the region where the engraved face is to be imprinted, the compression coil spring 104 is compressed, and the end face of the tube 130 moves to the engraved face and can be imprinted. Since the seal substrate 10 is formed in the shape of a hexagonal prism, the direction of the engraved face on the engraved face can be easily understood, and the seal and the like can be stamped in a straight direction.

  When the ink is consumed, the holder 113 is turned to release the protrusion 113 of the outer cylinder 110 from the locking part 24 of the connecting part 22, and the holder 101 is separated from the seal substrate 10. The ink is supplied to the ink absorber 105 by removing the stopper 140 closing the end. After that, the base end of the inner cylinder 120 is closed with the stopper 140 so that the ink does not leak from the inner cylinder 120. Then, the projection 113 of the outer cylindrical portion 110 is engaged with the locking portion 24 of the connecting portion 22, so that the seal substrate 10 and the holder 101 are integrated so as not to be easily separated.

  Note that the seal 100 according to the present invention can be variously modified within the scope of the technical matters described in the claims without being limited to the above embodiment. For example, the connecting portion 22 protruding from the bottom surface 21 of the cylindrical body 20 has a female screw formed on the inner surface, and a male screw that is screwed with the female screw is formed on the base end portion 101a of the holder 101, thereby obtaining a seal. The base material 10 and the holder 101 may be connected.

  In addition, the seal portion 102 can be similarly implemented even if a vermilion is separately required instead of a penetration mark. Furthermore, the seal 100 according to the present invention is not limited to the seal substrate 10 according to the first embodiment, but may be similarly applied to the seal substrates 11 and 12 described in the second embodiment or the third embodiment. can do.
