Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a self-contained porous stamp that uses quick-drying ink, and particularly to a stamp that allows the cap to be opened and closed without having to manually attach and detach the cap during marking work, enabling airtight maintenance with a small pressing force. Is.

[0002]

[Prior Art]

 Conventionally, the stamp has been in a state in which the cap can be manually picked and stamped. However, there was a problem of inconvenience to take by hand. Therefore, there are various mechanisms that can open and close the cap as well as the marking operation, for example, Japanese Utility Model Publication No. 58-11584 [hereinafter (a)]. If the cap is to be understood in a broad sense, it is possible to use an ink storage material impregnated with ink in the cap, as described in Japanese Utility Model Publication No. 48-3407 [hereinafter (b)] and Japanese Utility Model Publication No. 48-18207 [ Below (C)]. Furthermore, the stamps using quick-drying ink and provided with packing are Jikken Sho 60-21237 [above (d)] and Jikkaihei 3-116963 [below (e)]. However, in (a) above, a quick-drying ink is not used, and airtightness is not considered. Therefore, it has a drawback in terms of hermeticity. (B) and (c) are intended to apply ink to the stamp and have the same drawbacks as (a) above. In (d), quick-drying ink is used, the cap is provided with packing, and the cap and the main body are screw-fitted to maintain airtightness. (E) is provided with a U-shaped packing, and an independently separable cap is pressed against the main body, and the packing and the claws on both sides hold the cap and the main body airtight. Therefore, there is a drawback that the cap cannot be opened and closed and the airtightness cannot be easily maintained as in (a). In addition, in order to press the packing and keep it airtight, a strong pressing force is required if the packing of (a) and (e) is attached. This is because even if the packing is U-shaped, even if a weak pressing force is applied from the opening side, the opening side is in contact with the holding wall (opening side is upward and closed side is downward). The parallel two sides of the U-shaped packing hinder the packing from contracting. Therefore, the cap pressing force must be increased, and the structure becomes strong.

[0003]

[Problems to be solved by the device]

 As described above, the present invention overcomes the drawbacks of the prior art. Therefore, the purpose of the present invention is to easily maintain the airtightness by using a quick-drying ink with a weak (small) pressing force, and to easily open and close the cap during the marking work.

[0004]

[Means for solving problems]

 The cylindrical main body 1 has a continuous porous printing body 2 impregnated with quick-drying ink at the lower opening end, and a replenishment port plug 6 is fitted to the upper opening end of the main body 1 serving as an ink inlet. An elastic member 19 that elastically supports the main body portion A is provided around the main body portion A. A lower outer cylinder 12 is provided on the outer periphery of the elastic member 19 and a lower opening of the lower outer cylinder 12 is provided. A lower packing 14 held by a fixing ring 15 ′ is provided near the end, and a shaft 27 and a spring member 28 make airtight pressure contact with the lower packing 14 on the outer surface of the lower outer cylinder 12 to rotatably attach a cap portion 25. Further, a pressing portion 10 having a locking portion 22 arranged therein and having a collar 9 at its lower end is provided above the main body portion A, and the outer periphery thereof has the above-mentioned collar 9 at its lower opening end. An upper packing 8 fixed by a fixing ring 15 capable of maintaining airtightness is provided, and Upper outer casing 17 of outer sleeve 12 and the gas-tight press fit is stamp, characterized in that provided to cover the pressing portion 10.

[Action]

 The operation of the present invention will be described with reference to FIGS. 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 pressed against the lower packing 14 by the spring member 28 provided around the shaft 27 to maintain airtightness. I'm doing it. At this time, in the lower packing whose opening side 35 is an outward U-shape, the side close to the cap part is pressed by the cap part and the parallel side parallel to the center line of the main body is displaced toward the center to maintain the airtightness with the receiver. To do. In this way, the airtightness of the two parts of the cap part, the receiving plate and the lower packing is maintained. The body A is elastically supported by the elastic member 19, and the collar 9 and the upper packing 8 are in contact with each other. At this time, in the U-shaped upper packing with 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 center line of the main body is displaced toward the center, and the side surface of the holding cover 7 Keep airtight. Therefore, since the upper and lower parts are airtightly held and the upper outer cylinder 17 and the lower outer cylinder 12 are fitted so as to be airtightly maintained, 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 with a finger or the like, the pressing portion 10 is pushed down against the elastic force of the elastic member 19, and further provided below this. Push down the main part A that was taken. Then, the upper packing 8, the collar 9 and the holding cover 7 are hermetically sealed, and the spring member 28 attached to the shaft 27 rotates the cap portion 25 and the receiving portion 3 which are given a turning force in a direction of closing the upper end surface of the cutout window 13. And the airtightness of the lower packing 14 is released. At this time, when the pressing force with which the collar 9 presses the upper packing 8 is released, the airtight contact between the collar 9 and the upper packing 8 / the upper packing 8 and the holding cover 7 is released, and the cap portion 25 is attached to the lower packing. When the pressing force pressing 14 is also released, the airtight contact between the cap portion 25, the lower packing 14, and the lower packing 14, and the receiving metal 3 is released. During this period from the time of non-use to this time, the elastically 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 protrusion 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 state where the marking is possible is made. At this time, the receiving metal 3 continues to press the cap portion 25 against the turning force of the spring member 28. The locking portion 22 is locked by a claw 30 provided in the U-shaped notch 11 of the pressing portion 10, the stamp surface is located below the opening end of the lower outer cylinder 12, and is maintained in a state capable of being stamped. be able to. Then, the protrusion 32 surely protrudes more than during the movement. Further, when the stamping work is completed and the stamp face needs to be stored, when the protrusion 32 of the locking portion 22 protruding from the outer peripheral surface of the upper outer cylinder 17 is pushed with a finger (from right to left in FIG. 3), the claw 30 is engaged. The engagement with the stopper 22 is disengaged, and the restoring elastic force of the elastic member causes the main body A, the pressing portion 10 and the convex portion 16 to rise upward, and the locking portion 22 slides in the notch 11. At the same time, the contact between the receiving metal 3 and the cap portion 25 is released, and the cap portion 25 and the receiving metal 3 are pressed into contact with the lower packing 14 and the upper packing 8 with the flange 9 and the holding cover 7 to keep airtightness again. ..
