Description

Technical Field

[0001] The present invention relates to a pen-type permeation stamp for transferring an image composed of a desired design drawing, text, numbers, symbols, or a combination thereof to a desired position on an object such as a calendar, schedule notebook, or memo pad.

Background Art

[0002] There are already known display stamps for schedules and the like for imprinting a desired design drawing (pattern, character, etc.) on a calendar, schedule notebook, or the like.

[0003] An example of such a display stamp for schedules and the like is formed by detachably connecting a plurality of block bodies. At one end of each block body, a protruding portion is formed, and a permeation body is mounted inside the protruding portion. The protruding portion of another block body to which the other end side is connected is configured as a detachable connecting portion. Different design drawings and the like are printed on the printing surface of the permeation body of each block body, and the same display content as the various design drawings and the like printed on the printing surface of each block body is displayed on the outer surface of each block body (see Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] The conventional stamp for displaying schedules, etc., disclosed in the above-mentioned Patent Document 1, comprises a plurality of detachably connected block bodies, a clip-attached cap connected to the uppermost block body, and a protective cap connected to the lowermost block body. These block bodies, clip-attached caps, and protective caps are all cylindrical bodies having a polygonal (e.g., octagonal) cross-section, and when connected, they form a pen shape.

[0006] Conventional stamps for displaying schedules and the like are self-inking stamps, in which annular projections are formed concentrically and axially downward at one end of each block body, and a penetrating body consisting of an ink-impregnated body and a stamp surface on which a design drawing or the like is printed on a porous rubber plate is provided within these projections.

[0007] However, because self-inking stamps have limitations on the amount of ink that can be impregnated into the ink-impregnated material and / or porous rubber plate, there is naturally a limit to the number of times they can be used. When the number of impressions exceeds a certain limit, the quality of the image transferred to the object deteriorates. Typically, this results in the image becoming fainter or blurred. Therefore, it is common practice to make refill ink available separately in bottles or other containers so that the number of impressions can be extended by replenishing the ink-impregnated material and / or porous rubber plate.

[0008] However, the refill ink had to be stored separately from the stamps used for marking schedules and other information, which presented a challenge as it wasn't possible to immediately access and refill the ink when needed.

[0009] Furthermore, users who frequently carry traditional schedule stamps, for example, in their bags along with their schedule notebooks or planners, are likely to want to carry refill ink with them so they can immediately replenish the ink if the image becomes blurry or faded. However, carrying refill ink presents challenges, such as the risk of losing the ink or damaging personal belongings due to a broken ink container.

[0010] On the other hand, conventional stamps used for displaying schedules and the like have a circular stamp surface located within an annular projection, which presents a challenge in that it is difficult to include a lot of information in the image transferred from the circular stamp surface.

[0011] In addition, conventional stamps used for displaying schedules and other information presented difficulties in accurately aligning the image (adjusting its position and orientation) while stamping. In other words, there was a challenge in maintaining the horizontal alignment of the image on the stamp surface and precisely transferring the image to the desired location.

[0012] Therefore, this invention was made to solve the above-mentioned problems, and the objective of this invention is to provide a pen-type self-inking stamp that allows for immediate ink replenishment when needed and prevents loss or damage to personal belongings when carried around.

[0013] Another objective of this invention is to provide a pen-type self-inking stamp that can transfer images containing more information.

[0014] Another objective of this invention is to provide a pen-type self-inking stamp that allows for pinpoint transfer of an image while maintaining a horizontal position and aiming at a desired location. [Means for solving the problem]

[0015] In one embodiment of the present invention, the pen-type self-inking stamp includes two or more bodies that are fitted and separable in the axial direction, each of the two or more bodies includes a forward protrusion for holding a rectangular stamp surface and a rear recess, and preferably, a storage section for storing one or more refill inks is formed in the rear recess of at least one of the two or more bodies.

[0016] In a preferred embodiment of the present invention, a pair of retaining protrusions and a pair of keys are formed on the inner surface of the rear recess of one of the main bodies, and a pair of retaining recesses and a pair of L-shaped key grooves are formed on the outer surface of the front protrusion of the other main body, or a pair of retaining protrusions and a pair of keys are formed on the outer surface of the front protrusion of the other main body, and a pair of retaining recesses and a pair of L-shaped key grooves are formed on the inner surface of the rear recess of one of the main bodies, and when the one main body or the other main body is rotated after the pair of keys are inserted along the pair of L-shaped key grooves, the rear recess of one of the main body and the front protrusion of the other main body are fitted together.

[0017] Furthermore, in a preferred embodiment of the present invention, when the rear recess and the front protrusion are fitted together, the pair of retaining protrusions are positioned in the pair of retaining recesses, and the pair of keys engage with the pair of L-shaped keyways.

[0018] Furthermore, it is preferable that a marker is formed on the outer surface of the forward protrusion, which is positioned substantially parallel to at least one side of the rectangular marking surface.

[0019] Furthermore, the marker may be two or more raised ridges, two or more recessed grooves, or a textured surface, or a combination thereof, formed on the outer surface of the forward protrusion. [Effects of the Invention]

[0020] Since the stamp surface held by the forward protrusion on each of the two or more main bodies is a rectangular stamp surface, it is possible to transfer images containing more information, but this also accelerates ink consumption. According to one embodiment of this invention, when the ink is consumed and needs to be refilled, refill ink can be immediately taken out of the storage compartment and refilled. Moreover, since there is no need to store or carry the refill ink separately from the main body of the self-inking stamp, the risk of loss of refill ink or contamination due to damage to the container can be avoided.

[0021] In a preferred embodiment, after inserting a pair of keys formed on the inner surface of the rear recess of one main body along a pair of L-shaped key grooves formed on the outer surface of the front convex portion of the other main body, when one main body or the other main body is rotated, a pair of holding convex portions formed on the inner surface of the rear recess of one main body engages with a pair of holding recesses formed on the outer surface of the front convex portion of the other main body. Thereby, even if the inner surface of the rear recess of one main body forms a shape other than a cylindrical inner surface and the outer surface of the front convex portion of the other main body having a rectangular impression surface forms a shape other than a cylindrical outer surface, the engagement between the key and the key groove and the engagement between the holding convex portion and the holding recess can achieve a fitting without looseness between the main bodies.

[0022] In a preferred embodiment, on the outer surface of the front convex portion, markers (for example, two or more convex ridges, two or more concave grooves, or a dimpled surface, or a combination thereof) are formed substantially parallel to at least one side of the rectangular impression surface, so that it is possible to perform an imprinting operation while accurately aligning (adjusting the position and direction) the image.

[0023] The above-mentioned objects and advantages of the present invention and other objects and advantages will be more clearly understood through the following description of the embodiments. However, the embodiments described below are illustrative, and the present invention is not limited thereto.

[Modes for carrying out the invention]

[0025] A preferred embodiment of the pen-type self-inking stamp according to the present invention will be described in detail below with reference to the drawings.

[0026] Referring to Figures 1 to 5, the pen-type self-inking stamp 1 includes two or more bodies 10, 11 that can be fitted and separated in the axial direction. Each of the two or more bodies 10, 11 includes a forward projection 10F, 11F that holds a rectangular stamp surface 15, and a rear recess 10B, 11B. A storage compartment S for storing one or more refill inks 20 is formed in the rear recess 11B of at least one of the two or more bodies 10, 11. Note that 12 is a rear cap, and its skirt 12S, which extends downward, engages with the inner surface of the rear recess 11B of the body 11. Also, 13 is a front cap, and as will be described later, its rear recess 13B is configured to engage with the forward projection 10F of the body 10. In the illustrated example, there are seven bodies 10, 11, but the number is arbitrary and can be two or more, allowing for the transfer of as many different images as there are bodies.

[0027] In the example shown in the figure, the main body 10, 11, the rear cap 12, and the front cap 13 may have a rounded rectangular prism shape, and when all of them are fitted together, they may be configured to form a pen-type shape with minimal surface steps, as shown in Figure 1. However, this is just one example, and these shapes are not particularly limited.

[0028] The storage compartment S formed in the rear recess 11B of the main body 11 should be sized (length, width, and height) to accommodate, for example, three refill inks, each filled with ink of the same or different colors in a bottle-shaped container, arranged in a triangular pattern. The inner shape and structure of the storage compartment S, and the inner shape and structure of the skirt 12S of the rear cap 12, should be appropriately determined to prevent the refill ink 20 from moving around unnecessarily inside the storage compartment S.

[0029] The forward projections 10F and 11F may have an elliptical or oval shape. A stamp surface holding portion consisting of a rectangular recess is formed at the tip of the columnar forward projections 10F and 11F, where the rectangular stamp surface 15 is held. On one pair of sides of the columnar forward projections 10F and 11F (the front and back in Figures 4 and 5), a pair of holding recesses 102 are formed, and on the other pair of sides (the right and left sides in Figures 4 and 5), a pair of L-shaped key grooves 104 are formed. As shown in the figures, the holding recesses 102 may be formed by recessing the peak of a mountain shape that rises from the surface of the forward projection in a half-pipe shape. In addition, a stopper 105 that rises from the bottom surface of the groove may be formed at the bottom of the L-shaped key groove 104.

[0030] Furthermore, the sides of the columnar forward protrusions 10F and 11F may be formed with raised ridges 111, recessed grooves 112, and textured surfaces 113, which function as markers for precise alignment of the image.

[0031] The inner surfaces of the rear recesses 10B and 13B may have an elliptical or oval shape. On one pair of surfaces (the front and back in Figure 5) of the inner surfaces of the rear recesses 10B and 13B, a pair of retaining protrusions 101 are formed, and on the other pair of surfaces (the right and left sides in Figure 5), a pair of keys 103 are formed. As shown in the figure, the retaining protrusions 101 may be formed to bulge out in a semi-cylindrical shape.

[0032] Excluding the rectangular stamp surface 15, the main body 10, 11, rear cap 12, and front cap 13 can be made from plastics such as ABS (acrylonitrile butadiene styrene), PE (polyethylene), PC (polycarbonate), POM (polyacetal), AS (acrylonitrile styrene), PS (polystyrene), and PP (polypropylene). The shapes of the main body 10, 11, rear cap 12, and front cap 13 can all be molded integrally using injection molding plastic processing technology by creating molds for each part, and by partially texturing the molds for the main body 10 and 11 as needed. However, the shape and structure are not limited to specific processing technologies or processes.

[0033] The rectangular stamp surface 15 can be made from a porous sheet with open cells, which is molded by adding a foaming agent to a resin or rubber such as thermoplastic silicone resin, urethane resin, or thermoplastic polyethylene resin.

[0034] The ink may be, for example, a quick-drying ink containing formaldehyde resin, benzyl alcohol, octyl diphenyl phosphate, propylene glycol ethers, glycol ethers, and dyes. This ink can be directly impregnated into the rectangular stamp surface 15, or it can be stored in a bottle-shaped container for refill ink 20.

[0035] Referring to Figure 4, the outer surface of the front projection 10F may have markers formed on it that are positioned substantially parallel to at least one side of the rectangular stamp surface 15 (for example, two or more raised ridges 111, two or more recessed grooves 112 and L-shaped key grooves 104 that extend in the axial direction, or a textured surface 113, or a combination thereof). For example, the two raised ridges 111 and the textured surface 113 on the front and back of the front projection 10F may be formed to match the lateral position of the original image formed on the rectangular stamp surface 15. Similarly, the grooves that extend in the axial direction on both the left and right sides of the front projection 10F, including the recessed grooves 112 and L-shaped key grooves 104, may be formed to match the vertical position of the original image formed on the rectangular stamp surface 15. With this configuration, the user can hold the outer circumference of the rear recess 10B side of the main body 10 with their fingers and stamp while accurately aligning the image (adjusting the position and direction) by relying on the markers, without directly looking at the original image on the rectangular stamp surface 15. This also applies to the main body 11 in which a storage compartment S is formed in the rear recess 11B.

[0036] Next, with reference to Figures 6 and 7, the mechanism by which the rear recess 10B of one body 10 and the front protrusion 10F of the other body 10 engage when the two bodies 10 are fitted together in the axial direction will be explained in detail.

[0037] Align the pair of keys 103 in the rear recess 10B of one body 10 with the pair of L-shaped key grooves 104 in the front projection 10F of the other body 10. At this time, the front projection 10F is in a positional relationship rotated by a predetermined angle relative to the rear recess 10B. In this state, insert the keys 103 along the L-shaped key grooves 104. Figure 6 shows a cross-sectional view of the positional relationship between the front projection 10F and the rear recess 10B when the keys are inserted in this manner. The pair of retaining projections 101 of the rear recess 10B are located at the base of the mountain shape formed by the pair of recesses 102 of the front projection 10 at its apex. From this state, rotate the other body 10 by a predetermined angle relative to the first body 10. This rotation operation is indicated by arrows in Figure 6.

[0038] As shown in Figure 7, this rotational operation causes a pair of retaining protrusions 101 on one body 10 to be positioned in a pair of retaining recesses 102 on the other body 10, and a pair of keys 103 on one body 10 to engage with a pair of L-shaped key grooves 104 on the other body 10. This completes the fitting of the rear recess 10B of one body 10 with the front protrusion of the other body 10. If a stopper 105 is formed at the bottom of the L-shaped key groove 104, the stopper 105 functions to suppress the circumferential movement of the key, thus helping to prevent unintended rotation of the bodies or separation of the bodies.

[0039] According to a preferred embodiment, even if the inner surface of the rear recess 10B of one body 10 has a shape other than a cylindrical inner surface, represented by an elliptical or oval contour, and the outer surface of the front projection 10F of the other body 10, which has a rectangular stamp surface 15, has a shape other than a cylindrical outer surface, represented by an elliptical or oval contour, there is an excellent advantage in that a secure fit between the bodies can be achieved by the engagement of the key and the keyway, and the engagement of the retaining projection and the retaining recess.

[0040] To separate the main bodies, one simply needs to perform the reverse rotation and pulling operations described above for fitting the main bodies together. The same operations apply to fitting and separating the main bodies 10 together, as well as fitting and separating the main body 10 and main body 11, and fitting and separating the front cap 13 and main body 10 (see Figure 3).

[0041] Although preferred embodiments have been described in detail above, various modifications can be made to their components. For example, an ink-impregnated body may be provided on the back of the rectangular stamp surface 15. Regarding the marker formed on the forward protrusion 10, the marker is described as consisting of a combination of two or more protrusions 111, two or more recessed grooves 112 and an axially extending groove among the L-shaped keyway 104, and a textured surface 113, but the marker may consist of any one of the two or more protrusions, two or more recessed grooves, and a textured surface.

[0042] As shown in Figures 1 and 2, the main body 11 located at the rear has a hole formed in one of its rounded corners for passing a strap through, but alternatively, a clip integrated with the main body 11 may be provided.

[0043] Furthermore, one body, on which a pair of retaining protrusions and a pair of keys are formed, may be swapped with the other body, on which a pair of retaining recesses and a pair of L-shaped keyways are formed. That is, the outer surface of the front protrusion of the other body may be formed with a pair of retaining protrusions and a pair of keys, while the inner surface of the rear recess of the one body may be formed with a pair of retaining recesses and a pair of L-shaped keyways. Even with this configuration, a secure fit between the bodies can be achieved through the engagement of the keys and keyways, and the engagement of the retaining protrusions and retaining recesses.
