Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to stamps.

[0002]

[Prior art]

 For stamping, a so-called rubber stamp is used to apply stamping ink containing ink to a stamp surface and stamp it on documents, etc. (conventional technology 1), or an ink occluding body is placed on the back side of the stamp surface where ink penetrates. There is a so-called penetrating stamp (Prior Art 2) that can be placed and stamped without using a stamp table.

[0003]

[Problems to be solved by the invention]

 The rubber stamp of the prior art 1 is configured by attaching a stamp member made of natural rubber to the lower surface of a wooden or acrylic stamp base called a stock or a holder, and holding the stamp base, which is a hand-held portion, with the hand. It can be stamped by applying ink from a stamp stand to the surface. However, in the rubber stamp of the prior art 1, since the stamp surface member is solid rubber and the ink on the stamp base only sticks to the stamp surface, it can be imprinted only once or twice even if the ink is applied to the stamp surface. However, if the stamp is further applied, the characters become extremely thin, so that it is necessary to apply ink again to the stamp surface from the stamp base, which is a complicated stamping operation.

Therefore, the rubber stamp of the prior art 1 is inconvenient for office work that requires continuous printing on a large number of documents and the like. Moreover, according to the confirmation of the present inventors, the rubber stamp made of natural rubber of the prior art 1 is relatively hard, so that when the stamp face is 20 × 60 mm, 5 kg (416 g / cm) is obtained. ^Two ) Cannot be clearly imprinted without high printing pressure (pressing), for example, 1 kg (83 g / cm^Two), The impression was too thin. For this reason, it is necessary for the stamping operator to apply force so that the stamping can be performed clearly. In the case of office work that requires many stamping operations, there is a problem that the operator is easily tired.

On the other hand, the penetration type stamp of the prior art 2 is suitable for continuous stamping because it has an ink occluding body and does not require a stamp table when used. However, the structure of the penetration type stamp of the prior art 2 is very complicated because the stamp base is not required with the ink occluding body. Therefore, penetration stamps are expensive, and rubber stamps, which are cheaper than penetration stamps, are widely used as office supplies. As a result, the prior arts 1 and 2 have not eliminated the complexity of the stamping operation.

The present invention has been made in view of such a problem, and a problem thereof is to make a stamping operation easier than a conventional rubber stamp without increasing costs.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention does not use a penetrating type stamp with an ink absorbing body, which increases the cost, but attaches a stamping member to a stamping substrate and applies ink to the stamping surface from a stamp stand or the like during use to stamp. Adopted a stamp. As a stamp surface member on which the stamp surface is formed, a porous material having open cells was employed. That is, in the stamp of the present invention, the stamp face member made of a porous material having open cells is attached to the stamp base without interposing the ink occluding body.

By employing a porous material having open cells as the stamp face member, the ink is impregnated into the stamp face member when ink is applied to the stamp face member. By imprinting with the ink impregnated on the stamping surface member, a relatively clear imprint can be obtained even if imprinting is performed several times. Therefore, the number of times that the ink on the stamp table is applied to the stamp is reduced, and the stamp can be easily performed. In addition, in the conventional rubber stamp, only the surface of the stamp surface is inked. Therefore, when the stamp is used once or twice and the surface of the stamp surface runs out of ink, the imprint becomes extremely thin even when the stamp is applied. By impregnating the stamp surface member with the stamp surface member, the stamp surface member has a liquid replenishing property, and even if the stamp is continuously imprinted, the ink impregnated in the stamp surface member is supplied to the stamp surface, and the imprint is prevented from becoming extremely thin. .

In addition, by adopting a porous material as the stamp face member, the stamp face member is soft, a relatively clear imprint can be obtained even with a low printing pressure, and stamping can be performed easily. The stamp surface member is preferably a porous rubber that has continuous cells and can be impregnated with ink. In addition, the stamp surface member made of a porous material having open cells can be directly or indirectly attached to a stamp base such as a handle portion. In the case of indirect attachment, the stamp surface member is substantially inked. It is preferable to attach to the stamp substrate with a sheet material which is not impregnated.

When the stamping member impregnated with the ink is directly attached to the stamp substrate, the ink impregnated on the stamp member may adhere to the stamp substrate and stain the stamp substrate with the ink. If the stamp member is attached to the stamp base with a sheet material interposed therebetween, the ink impregnated in the stamp face member becomes difficult to transfer to the stamp base member due to the presence of the sheet material, thereby preventing the stamp base from being stained. Further, the sheet material is preferably a cushion material made of a porous material having closed cells and substantially not impregnated with ink.

[0011] In order to make the stamp surface member soft and to facilitate the stamping, it is preferable to increase the thickness of the stamp surface member to enhance flexibility. Moreover, when the stamp face member is thickened, the ink impregnation capacity of the stamp face member can be increased, and the number of times of continuous stamping can be increased. From this point of view, it is also possible to attach a relatively thick stamping surface member directly to the stamp substrate. However, if the stamp surface member is directly attached to the stamp substrate, the stamp substrate tends to become dirty as described above. Further, if the stamp member is thickened to increase the ink impregnating capacity, a large amount of ink is impregnated, and the stamping member is used. In this case, the stamp surface member is compressed and the ink exudes, so that the stamp substrate and the document are easily stained.

On the other hand, if the stamp face member is made thin to prevent this, the flexibility of the stamp face member cannot be sufficiently exhibited. In order to solve such a problem, as described above, it is preferable to attach the stamp face member to the stamp base with a cushion material made of a porous material having closed cells and substantially not impregnated with ink interposed therebetween. . By adopting such a structure, flexibility is secured by the thickness of both the stamp face member and the cushion material, and the ink is impregnated only into the stamp face member and not into the cushion material. It can be made relatively low, and can prevent the stamp substrate and the like from being stained by the ink.

[0013] From this viewpoint, another aspect of the present invention includes a stamp substrate having an attaching surface, a cushion material attached to the attaching surface of the stamp substrate, and a stamp member attached to the cushion material. Wherein the cushioning material is made of a porous material having closed cells and substantially not impregnated with ink, and the stamping surface member has continuous cells and a cushioning property capable of impregnating with ink. It is characterized by comprising a porous material having: Still another aspect of the present invention is to laminate a first porous sheet having open cells and capable of impregnating ink and a second porous sheet having closed cells and substantially not impregnated with ink. And a stamped surface formed on the first porous sheet.

Further, another aspect of the present invention is to attach a second porous sheet to a non-marked surface of a first porous sheet having a stamped surface and having open cells and being impregnated with ink via a sticking member. And that the ink impregnated in the first porous sheet is prevented from migrating to the second porous sheet side by the attaching member. In this case, since the ink is prevented from being transferred from the first porous sheet to the second porous sheet by the attaching member, the flexibility can be ensured in both the first and second porous sheets. In addition, since only the first porous sheet is impregnated with the ink, the ink impregnation capacity can be reduced. Note that a double-sided tape, an adhesive, or the like can be used as the attaching member.

[0015]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 and 2 show a stamp 1 according to the first embodiment. The stamp includes a stamp base 2, a sheet-like cushion material (second porous sheet) 3 provided on the lower surface of the stamp base 2, and a stamp member (first porous member) provided below the cushion material 3. Sheet 5), and stamps the stamp surface member 5 by applying ink from a stamp stand or the like.

The stamp substrate 2 is also a hand-held portion to be held in a hand at the time of use, and may be made of wood or acrylic, but the material is not limited. The stamp substrate 2 has a concave curved surface on the side surface 2a so as to fit the hand. The upper surface 2b of the seal 2 is a display unit on which the same characters as the seal are printed. The lower end surface 2c of the stamp substrate 2 is formed flat and serves as an attachment surface to which the cushion material 3 is attached. Note that the sticking surface 2c may be formed in a convex curved shape. When formed in a convex curved shape, a roll-shaped stamp can be obtained.

The stamp base 2 of the stamp 1 does not need to be formed in a cylindrical case shape for incorporating the ink occluding body like a penetrating stamp, and it is not necessary to attach a spring or the like inside. The structure is simple because it is sufficient. The side surfaces of the cushion member 3 and the stamp member 5 are not covered with the stamp substrate 2 and are exposed. The cushion material 3 is formed by cutting a porous sheet (sponge sheet) made of natural rubber or synthetic rubber into a predetermined shape, and has a size substantially the same as or slightly smaller than the sticking surface 2c of the stamp substrate 2. Have been. It has the same or similar shape as the sticking surface 2c. Here, since the sticking surface 2c of the stamp substrate 2 is rectangular, the cushion member 3 is also formed in a rectangular shape.

One surface (upper surface) of the cushion material 3 is attached to the stamp base 2 via an attaching member 6. Here, a double-sided tape having substantially the same size as the cushion material is used as the attaching member 6, but may be an adhesive. The cushion material 3 is thinner than the stamp face member 4, and is about 1.5 mm here. The cushion material 3 is given a different color from that of the stamp face member 4 in order to give a color accent. For example, the stamp surface member 5 can be black and the cushion material 3 can be orange.

The cushion material 3 is a closed-cell porous rubber sheet. Accordingly, the cushion material 3 is not substantially impregnated with ink. Note that the cushion material may be a solid type (porosity is almost 0%) instead of a sponge sheet such as a porous material as long as a desired cushioning property can be obtained. If it is a solid type, it does not impregnate the ink. However, since the closed-cell porous rubber sheet has irregularities on the surface, it is difficult for the leaked ink to reach the stamp substrate 2 and is advantageous from the viewpoint of preventing contamination.

Note that the cushion material 3 can be omitted. In this case, the stamp member 5 is directly attached to the stamp substrate 2 with an attaching member such as a double-sided tape. The stamp face member 5 is formed by cutting a porous sheet (sponge sheet) made of natural rubber or synthetic rubber into a predetermined shape, and is formed in the same general shape as the cushion material 3. Here, the stamp face member 4 has a rectangular shape. The stamp face member 5 has a lower face 5 as a stamp face, and an upper face that is a non-seal face is attached to the cushion material 3 via an attaching member 7. Here, a double-sided tape having the same size as the cushion material 3 (or the stamp face member 5) is used as the attaching member 7, but may be an adhesive. Further, the stamp face member 5 is thicker than the cushion material 3 and can be, for example, about 2.5 to 3.5 mm, and preferably about 3 mm. Further, when the cushion material 3 is omitted, it is preferable that the thickness is about 3 to 4 mm so as to be thicker.

The stamp face member 5 is an open-cell porous rubber sheet. Therefore, the printing member can be impregnated with the ink and has a function of replacing the ink. If the stamp member 5 is brought into contact with the stamp base and the ink is applied to the stamp member 5, the ink is replenished to the stamp surface by the replenishment function of the stamp member 5 even when the stamp is applied, and the stamp surface is relatively clear even if stamped several times. You can get a good impression. Since the cushion material 3 is made of a closed-cell porous material, the ink impregnated in the stamp face member 5 does not transfer to the cushion material, and the ink is exclusively held in the stamp face member 5. Moreover, since the stamp face member 5 and the cushion material 3 are separated by the sticking member 7 and transfer of ink is hindered, even if the cushion material 3 is a material that can be impregnated with ink, the ink is not used. It is difficult to migrate.

Further, the stamp surface member 5 impregnated with ink is attached to the stamp substrate 2 with the cushion material 3 not impregnated with ink interposed therebetween, so that the stamp substrate 2 is not easily stained with ink. Further, the stamp face member 5 also has cushioning properties, and the cushioning property of the cushioning material 3 is enhanced, so that flexibility is enhanced, and a clear imprint can be obtained even when pressed lightly. In the stamp 1 of the present embodiment, when the stamp surface is 20 × 60 mm, a clear imprint was obtained even with a light impression of about 1 kg (83 g / cm ² ). Therefore, even if the seal is imprinted many times, there is little fatigue.

Further, since the flexibility is higher than that of the conventional rubber stamp of solid rubber, even when stamping an uneven surface such as a cardboard, the stamp surface is deformed along the uneven surface, and the uneven surface is clean. Can be stamped. The stamped surface can be obtained by engraving a desired shape with a laser engraving machine or the like. According to the present embodiment, the engraving of the stamp surface is easier than the conventional solid rubber rubber stamp, and the productivity by the laser engraving machine is 2 to 3 times as compared with the conventional one. For example, when a stamping process is performed with a 12W laser engraving machine, the conventional solid rubber requires 17 minutes, whereas the porous rubber as in the present embodiment requires about 8 minutes. .
