ABSTRACT:
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority to Japanese Patent Application 11-180637, filed Jun. 25, 1999.
Technical Field
This invention concerns a stamp pad with a rotatory lid and the manufacturing method thereof.
Background of the Invention
Traditionally, stamp pads are widely used for rubber stamp affixation. A stamp pad has an ink storage body and a pad base and is known to have various shapes and sizes.
Some of such stamp pads have lids removable from main bodies.
FIG. 8
shows a schematic cross-sectional view of an example of traditional stamp pads.
FIG. 9
is a schematic view of such a stamp pad with its lid opened. As shown in the figure, the traditional stamp pad consists of pad base
21
which has a concave surface
22
, with such concave surface
22
having an ink storage body
23
which is made of ink-absorbing material, such as sponge and cloth, into which ink is absorbed, with the top portion
29
of such ink storage body
23
permanently stored on the pad base
21
in the manner that the former somewhat protrudes from the latter, forming the main body
20
. The ink storage body
23
is covered from above by the lid
24
, with the periphery of the pad base
21
having a groove
25
engraved thereon, whereby the tip of the periphery of the lid
24
is engageable with the engraved groove
25
in a freely engaging and disengaging manner for the purpose of placing and removing the lid.
In affixing a rubber stamp using such a stamp pad, the lid
24
is removed from the main body
20
, the rubber stamp is pressed lightly on the ink storage body
23
of the stamp pad to apply ink on the stamp, and the stamp is affixed on paper and other applicable materials.
Some of the traditional stamp pads are known to have the structure which connects the main body and the lid with a hinge.
FIG. 10
shows a schematic cross-sectional view of an example of traditional stamp pads with hinges. As shown in the figure, the ink storage body
33
made of ink-absorbing material, such as felt or sponge, with ink absorbed in it, is seated in the pad base
31
, forming the main body
30
. The ink storage body
33
is covered from above by the lid
34
and the lid
34
and the main body
30
are connected to each other with the hinge
31
in a freely rotatory manner for the purpose of placing the lid.
A stamp pad with a removable lid as shown in
FIG. 9
requires a place to set the lid
24
when it is removed from the main body
20
as a rubber stamp is pressed on the ink storage body
23
of the stamp pad for ink application and stamp affixation.
Similarly, in the case of a stamp pad with the main body and the lid connected to each other with a hinge as shown in
FIG. 10
, the lid
34
occupies space when it is separated from the main body
30
and rotated 180 degrees to open it as a rubber stamp is pressed on the ink storage body
33
of the stamp pad for ink application and stamp affixation.
For these reasons, traditional stamp pads need a place to set the lids for stamp affixation. Moreover, the removable lids can be lost.
SUMMARY OF THE INVENTION
This invention is made to improve such shortcomings of the prior art as described above and is intended to provide a stamp pad with a rotatory lid and the manufacturing method thereof which eliminates the need for a place to set the lid by way of connecting a hinge plate to the main body and the rotatory lid in a freely rotatory manner and by way of rotating one full rotation the rotatory lid separated from the main body and storing the same underneath the main body, in which the hinge plate connected to the main body and the rotatory lid does not slip off easily and in which the hinge plate is easily connectable with the main body and the rotatory lid while the shape of the hinge plate is being changed.
