Abstract

PROBLEM TO BE SOLVED: To smoothly open a lid by easily pulling away the lid from a case body when the lid is to be opened even when the pressure in the lid is reduced due to change of temperature and the lid is sucked by the case body. SOLUTION: A back edge of a lid 2 is hinged to a back edge of a case body 1 for housing an inkpad. A hook piece is provided at the front edge of the lid 2. At the front edge of the case body 1, a lock button 25 in which the hook piece locks in a state that the lid is closed is provided. Further, a cam slant face 31 is provided at the front edge of the lid 2, and a protrusion 30 which abuts against the cam slant face 31 of the lid 2 when the lock button 25 operates to release the locked state of the hook piece of the lid 2 so as to push up the front edge of the lid 2 is provided at the lock button 25.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stamp base for transferring ink to a stamp surface.

[0002]

2. Description of the Related Art Heretofore, there has been known a stamp base having a structure in which a rear side of a lid body is hinged to a rear side of a case body containing an ink pad. In order to prevent the ink pad from drying, such a stamp base is often provided with a seal member for improving the sealing property in a closed state. However, when the sealing property is enhanced, there is a problem that the inside of the lid is decompressed due to a temperature change or the like, so that the lid is unlikely to be opened by adsorbing to the case body like a suction cup.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to solve the problem that even if the inside of the lid is decompressed due to a temperature change or the like and the lid adheres to the case body, the lid is opened from the case body. An object of the present invention is to provide a stamp base that can easily separate a body and open a lid smoothly.

[0004]

The above object is achieved by the present invention, that is, the rear side of the lid 2 is hinged to the rear side of the case body 1 for accommodating the ink pad 8, and the front of the lid 2 is provided. Hook pieces 23 and 24 are provided on the sides, and a lock button 25 for locking the hook pieces 23 and 24 in a closed state is provided on the front side of the case body 1. Is provided with a cam slope 31, and the hook pieces 23,
When the lock button 25 performs an operation for releasing the locked state of the cover 24, the cover 2 is brought into contact with the cam slope 31 of the cover 2.
The stamp base is characterized in that the lock button 25 is provided with the projection 30 for pushing up the front side of the stamp button.

[0005] In order to save the trouble of opening the lid 2, a spring 14 for automatically opening the lid 2 when the locked state of the hook pieces 23, 24 of the lid 2 and the lock button 25 is released. Is preferably attached between the lid 2 and the case body 1 on the rear side.

[0006]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. First, FIGS. 1 and 2 show a state in which the lid 2 is closed with respect to the case body 1. Hinge bearings 3 and 4 are protrudingly provided on the left and right sides of the rear side of the case body 1, respectively.
The lid 2 is openable and closable by rotatably fitting the small diameter portions of both ends of the hinge shaft portion 5 projecting from the rear side surface to the hinge bearing portions 3 and 4, that is, by hinged.

The case body 1 comprises a bottom plate 6, an upper frame 7 and a middle frame 12.
The case body 1 houses an ink pad 8. The ink pad 8 is composed of a cushion material 9 placed on the bottom plate 6, an ink occluding body 10 superimposed on the cushion material 9, and a top cloth 11 covering the top thereof. It is sandwiched between the frame 7 and the middle frame 12.

A frame-shaped rubber packing 1 is provided on the inner surface of the lid 2.
The packing 13 is attached to the surface of the upper frame 7 in a state in which the lid 2 is closed, and the ink pad 8 is prevented from drying by being tightly sealed.

A torsion coil spring 14 for automatically opening the cover 2 is mounted between the cover 2 and the case body 1. That is, as shown in FIGS. 2 and 4, a groove 15 is formed on the inner surface side of the hinge shaft 5 of the lid 2, and the torsion coil spring 1 is formed.
4 is accommodated in the groove 15 thereof,
The arm 17 at one end of the torsion coil spring 14 is sandwiched between the bottom plate 6 and the upper frame 7 of the case main body 1, and the L at the tip of the arm 17
The torsion coil spring 14 is fixed so as not to come off by inserting the bent portion 18 into the vertical hole 20 of the convex portion 19 provided on the rear surface of the bottom plate 6. The torsion coil spring 14
The arm 21 at the other end of the cover 2 comes into contact with the inner surface of the lid 2.

Next, as shown in FIG. 4, the lid 2 is provided with hook pieces 23 and 24 at both ends of the front side. On the other hand, a lock button 25 having locking holes 26 and 27 at both ends is installed at the front side of the case body 1, and the lid 2 is
Insert the lock buttons 2 and 3 into the lock holes 26 and 27
5, the closed state is maintained. The lock button 25 is a support shaft 2 protruding from both left and right ends.
8, 29, it is rotatably attached to the case body 1, and the bottom surface thereof is supported by the coil spring 22. When the front end of the lock button 25 is pressed downward, the lock button 25 is tilted to release the hook pieces 23 and 24 from the locking holes 26 and 27, and the lid 2 is automatically turned by the force of the torsion coil spring 14 described above. It is designed to open.

A protrusion 30 is provided at the center rear end of the upper surface of the lock button 25, and a recess 32 having a cam slope 31 is provided at the center of the front side of the lid 2.
In the closed state, the projection 30 of the lock button 25 is located slightly behind the concave portion 32 of the lid 2, and the slope 33 of the projection 30 and the cam slope 31 face each other. And the lock button 25
When the lock button 25 is inclined by pressing the front end portion downward, the slope 33 of the projection 30 comes into contact with the cam slope 31 to push up the lid 2 as shown in FIG.

[0012]

The stamp base of the present invention is as described above. The cam slope 31 is provided on the cover 2 and the projection 30 is provided on the lock button 25.
Even if the inside of the container is decompressed and the lid 2 is adsorbed on the case body 1,
By performing an operation of releasing the locked state between the hook pieces 23 and 24 of the lid 2 and the lock button 25, the projection 30 of the lock button 25 abuts on the cam slope 31 of the lid 2 and pushes up the lid 2. The lid 2 is forcibly separated from the case main body 1 so that the lid 2 can be opened smoothly. Further, if a spring 14 is attached between the lid 2 and the case body 1 as described in claim 2, the lid 2 is automatically opened, so that the labor for manually opening the lid can be omitted.
