Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-contained porous stamp using quick-drying ink, and particularly to opening and closing the cap without manually re-attaching and removing the cap during the stamping operation. And a seal which enables air-tightness to be maintained with a small pressing force. 2. Description of the Related Art Heretofore, a stamp has a state in which a cap can be manually stamped and stamped. However, there was a problem of inconvenience to take by hand. Therefore, there are various mechanisms that allow the cap to be opened and closed together with the stamping operation.
No. 84 [hereinafter (a)]. In addition, if the cap is taken in a broad sense, the cap may be provided with an ink occluding body impregnated with ink, as disclosed in Japanese Utility Model Laid-Open No. 48-3407 [hereinafter (b)] and Japanese Utility Model Laid-open No. 48-18207 [hereafter. (C)]. Further, there is a seal using a quick-drying ink and provided with a packing, Japanese Utility Model Publication No. Sho 60-21237 [more than (d)] and Japanese Utility Model Laid-Open No. 3-116963 [below (e)]. However, the method (a) does not use a quick-drying ink and does not consider airtightness. Therefore, it has a disadvantage in airtightness. (B) and (c) are intended to apply ink to a stamp, and have the same drawbacks as (a). In (d), quick-drying ink is used, packing is provided on the cap, and the cap and the main body are screw-fitted to keep the airtight. (E) is provided with a U-shaped packing, and presses an independently separable cap against the main body, and holds the packing and claws on both sides,
The cap and the body are kept airtight. Therefore,
There is a disadvantage that the cap cannot be easily opened and closed and airtightly maintained as in (a). In addition, in order to press the packing to maintain the airtightness, a strong pressing force is required if the packing (a) or (e) is attached. Because, even if the packing has a U shape, the opening side is in contact with the holding wall (the opening side is upward and the closing side is downward), so even if a weak pressing force is applied from the opening side, The two parallel sides of the U-shaped gasket hindered the shrinkage of the gasket. For this reason, the cap pressing force must be increased, and the structure becomes strong. [0003] As described above, the present invention overcomes the disadvantages of the prior art. Accordingly, it is an object of the present invention to use a quick-drying ink to easily maintain airtightness with a weak (less) pressing force, and to easily open and close the cap during the stamping operation. A tubular main body 1 has a continuous porous printed body 2 impregnated with quick-drying ink at a lower open end, and is provided above the main body 1 as an ink inlet. At the open end, an elastic member 19 for resiliently supporting the main body A is provided around the main body A to which the refill plug 6 is fitted. A lower packing 14 held by a fixing ring 15 ′ is provided near the lower opening end of the lower outer cylinder 12, and the lower packing 14 is airtightly sealed on the outer surface of the lower outer cylinder 12 by a shaft 27 and a spring member 28. The cap portion 25 is pivotally attached so as to be pressed and rotatable, and furthermore, the locking portion 22 is disposed inside, and the pressing portion 10 having the flange 9 at the lower end is provided above the main body portion A. Airtight fixed to the lower opening end by the collar 9 and the fixing ring 15 The lifting possible upper packing 8 provided a stamp of the upper outer cylinder 17 to hermetically press fit and the lower outer cylinder 12 is characterized in that provided to cover the pressing portion 10. The operation of the present invention will be described with reference to FIGS. 2, 3 and 5. When not in use, the stamp surface is located above the lower opening end of the lower outer cylinder 12, and the cap portion 25 is fixed to the lower packing 14 by a spring member 28 provided around a shaft 27.
To keep the airtight. At this time, the opening side 35
However, in the lower packing having an outward U-shape, the side close to the cap portion is pressed by the cap portion, and the parallel side parallel to the center line of the main body is shifted in the center direction, thereby maintaining airtightness with the receiver. In this way, the airtightness of the two places of the cap portion / receiving member and the lower packing is maintained. Further, the main body portion A is formed by the elastic member 19.
It is resiliently supported, and the flange 9 and the upper packing 8 are in contact. At this time, in the U-shaped upper packing having the opening side 35 facing outward, the side close to the flange 9 is pressed by the flange 9, and the parallel side parallel to the main body center line is shifted in the center direction, so that the side of the holding cover 7 can be moved. Keep airtight. Therefore, since the upper and lower parts are kept airtight and the upper outer cylinder 17 and the lower outer cylinder 12 are fitted so as to be able to maintain airtightness, the impregnated quick-drying ink does not dry. Next, when the convex portion 16 protruding from the upper end surface of the upper outer cylinder 17 is pressed by a finger or the like, the pressing portion 10 is pressed down against the elastic force of the elastic member 19, and is further provided below this. Press down the main body A that has been set. Then, the upper packing 8, the flange 9, and the holding cover 7 are hermetically sealed, and the cap member 25 and the metal receiver 3, which are given a rotational force in a direction to close the upper end surface of the cutout window 13 by the spring member 28 attached to the shaft 27. The airtightness of the lower packing 14 is released. At this time, when the pressing force with which the flange 9 presses the upper packing 8 is released, the airtight contact between the flange 9, the upper packing 8, the upper packing 8, and the holding cover 7 is released, and the cap 25 is moved to the lower packing. When the pressing force pressing the 14 is also released, the airtight contact between the cap portion 25, the lower packing 14, the lower packing 14, and the receiver 3 is released. During the period from the time of non-use to this time, the resiliently supported locking portion 22 can move the pressing portion 10 downward while pressing the inner wall of the upper outer cylinder 17. At this time, the projection 32 always projects from the hole 23. When further pressed, the stamp surface is positioned below the opening end of the lower outer cylinder 12 and the seal is ready for stamping. At this time,
The receiving member 3 is connected to the cap portion 2 against the rotational force of the spring member 28.
