Description

[Detailed Description of the Invention] The present invention relates to an improvement of a stamp whose printing surface is formed of a porous stamp material.

Stamps whose printing surface is formed using a porous printing material such as sponge rubber are widely used because they allow continuous printing without the need for stamp ink to adhere to the printing surface each time a stamp is stamped. There is a problem that it is not only difficult to do this properly, but also that it is easy to get your hands dirty when refilling the stamp ink.

The present invention was developed with the aim of creating a stamp that solves the above-mentioned problems, and the illustrated embodiment will be described in detail below.

Reference numeral 1 denotes a stamp main body, and the stamp main body 1 includes a short cylinder 3 made of a synthetic resin material with excellent solvent resistance such as polypropylene resin with an inner flange 2 provided at the lower end, and a peripheral edge supported by the inner flange 2. A porous stamp material 4 made of sponge rubber or the like is fitted into the short cylinder 3 in this state, an ink storage body 5 is attached to the top surface of the porous stamp material 4, and an ink storage body 5 is detachably attached to the short cylinder 3. It consists of a cover part 6 made of the same material that is fitted, and a handle 8 detachably attached to a short shaft 7 on the upper surface of the cover part 6.

Further, a short flange 9 is provided on the circumferential surface of the intermediate portion of the cover portion 6 of the stamp main body 1, and a sealing ring 10 such as a rubber O-ring is provided below the short flange 9. The sealing ring 10 is connected to a tapered upper end receiving surface 11' formed inside the upper end of the bottom cover 11 which is detachably attached to the stamp main body 1 so as to be in contact with the lower surface of the base of the short flange 9. Close to.

The relationship between the stamp body 1 and the bottom cover 11 is such that a male threaded portion 13 corresponding to the female threaded portion 12 formed on the inner circumferential surface of the bottom cover 11 is formed on the lower outer circumferential surface of the cover part 6. The bottom cover 11 can be detachably attached below the cover part 6 of the stamp main body 1 by screwing the female threaded part 12 and the male threaded part 13 together.

Furthermore, tongue-shaped arcuate protrusions 15 are provided in the cover part 6 at positions corresponding to the appropriate number of valley-shaped notches 14 provided at the upper end of the short cylinder 3, and the upper half of the short cylinder 3 The engagement recess 1 is engaged with the engagement protrusion 16 disposed on the outer peripheral surface of the engagement recess 1.
7 is provided, and when the arcuate protrusion 15 is aligned with the valley-shaped notch 14 and pressed in the vertical direction, the engagement protrusion 16 engages with the engagement recess 17, and the cover part 6 and the short cylindrical body 3 are However, if force is applied to rotate the short cylindrical body 3, the short cylindrical body 3 is guided by the tongue-shaped arcuate protrusion 15 and the valley-shaped notch 14.
is rotated to disengage the engagement protrusion 16 and the engagement recess 17, and the distal end surface of the engagement protrusion 16 has a gentle arc to facilitate such engagement and disengagement. formed on the surface.

Reference numeral 18 denotes anti-slip ridges provided vertically at required intervals on the outer circumferential surface of the lower half of the short cylinder 3. The lid 11 is raised to form an eave-like shape, and a recess 11a with an inner diameter slightly larger than the outside diameter of the short cylinder 3 is formed at the lower end so that the lower end blade part of the short cylinder 3 can be fitted into the lower end. A rotation prevention part 19 such as a ridge corresponding to the rotation prevention ridge 18 is provided on the inner circumferential surface of 11a, and the bottom cover 11 is inverted and fitted to the short cylinder body 3, and then the cover part 6 is fitted. If the bottom cover 11 is rotated with the sides fixed, the short cylindrical body 3 can be easily rotated and the cover part 6 and the short cylindrical body 3 can be easily rotated.
The connection with is now broken.

In the figure, reference numeral 20 denotes a vertical bulge provided on the inner circumferential surface of the thick bottom end of the short cylinder 3, and the bulge 20 engages with a notch 21 provided on the periphery of the porous stamp material 4 to form a porous stamp material. 22 is a long hole provided in the porous stamp material 4 for inserting the stamp, and 23 is an ink hole provided vertically on the top plate of the cover part 6. The occluding body presser 24 and 27 press the hollow portion 25 formed inside the stamp main body 1 into the stamp main body 1 and the bottom cover 11.
The cavity 2 is communicated with the cavity 26 formed between the
In order to be able to adjust the internal pressure difference of 5.26, there are communication narrow grooves and communication notches formed in the cover part 6, the three short cylinders, and the lower end of the ink storage body presser 23.

With this structure, if the ink absorbing body 5 absorbs stamp ink such as quick-drying stamp ink using a volatile solvent in advance, the porous hole made of sponge rubber or the like at the lower end of the stamp main body 1 can be used. An appropriate amount of stamp ink that has gradually oozed out onto the printing surface of the stamp material 4 is transferred to the short cylinder 3 of the stamp main body 1.
The bottom cover 11 attached to the lower end of the printer prevents the printer from drying out and also prevents the printed surface from touching and staining other objects.

However, when refilling the stamp ink, first remove the bottom cover 11 and then turn the bottom cover 11 upside down.
As shown in FIG.
If the bottom cover 11 is fitted into the recess 11a and rotated, the recess 11a
Since a detent portion 19 corresponding to the detent ridge 18 provided on the circumferential surface of the short cylindrical body 3 is provided on the inner circumferential surface of the short cylinder body 3,
Rotation force is also transmitted to the short cylinder 3 under the engagement of the ridge 18 and the rotation stopper 19.

Therefore, the cover of the stamp main body 1 is assembled by engaging the arcuate protrusion 15 and the engagement recess 17 with the trough-shaped notch 14 provided at the upper end and the engagement protrusion 16 for connecting part of the cover provided on the outer circumferential surface. The short cylindrical body 3 connected to the portion 6 has a valley-shaped notch 14 and an arc-shaped projection 15.
is rotated under the guidance of , the engagement between the engagement recess 17 and the engagement protrusion 6 is released, and the short cylinder 3 is left on the bottom lid 11 side and separated from the cover part 6 with the handle 8. Therefore, replenish the stamp ink from the upper end opening of the short cylinder 3, and after replenishing, align the valley-shaped notch 14 and the arcuate protrusion 15, and press the cover part 6 strongly against the short cylinder 3. Since both the cover portion 6 and the short cylinder body 3 are made of synthetic resin, the engagement protrusion 16 is elastically engaged with the engagement recess 17 under the guidance of the valley-shaped notch 14 and the arcuate protrusion 15. , the cover part 6 and the short cylinder body 3 are assembled into the stamp main body 1 which is connected and integrated, and during this process, the bottom cover 11 and the handle 8 are attached without touching the short cylinder body 3, where stamp ink tends to adhere. Since all you have to do is hold the cover part 6 and perform a series of attachment/detachment operations, there is no risk of getting your hands dirty.

In addition, when stamping, if the bottom cover 11 detachably attached to the stamp main body 1 is removed, and the handle 8 is grasped and a normal stamping operation is performed, continuous stamping can be performed with an appropriate amount of stamp ink leached onto the printing surface. It can be performed.

Therefore, the present invention has great practical value as a stamp using a porous stamp material that allows stamp ink to be replenished accurately and easily without staining hands and fingers.
