Description

The present invention relates to a sealing tag that makes it difficult to open the manhole cover illegally.

Conventionally, a technique has been used in which a label is attached to an adherend provided with an opened portion to prevent a third party from illegally opening the adherend. Further, in recent years, it has been considered that such a label can detect illegal peeling by a third party by leaving a trace of the peeling from the adherend (see, for example, Patent Document 1).

By the way, terrorist attacks such as bombings have occurred all over the world these days, and it is required to prevent terrorist attacks especially when a big event is held or when a VIP comes to Japan. One of the preventive measures against such terrorist attacks is to ensure the safety inside the manhole. If a bomb is set inside the manhole, it is expected that many casualties will occur indiscriminately, so it is important to prevent the manhole cover from being opened illegally from the viewpoint of ensuring safety inside the manhole. preferable.

Therefore, it is conceivable to attach a label as described above to the manhole cover and its surroundings so that the manhole cover cannot be opened illegally.

Manholes are generally laid on roads, but roads are often paved with asphalt, and as described above, to ensure safety inside the manhole, the manhole cover and the asphalt around it A label will be attached across the road.

However, asphalt has a number of recesses irregularly on its surface, so even if the label is attached across the manhole cover and the asphalt around it, the part of the label that is attached to the asphalt is easy. There is a problem that it will come off.

The present invention has been made in view of the problems of the conventional technique as described above, and the sealing tag can be prevented from being easily peeled off when the manhole cover and the asphalt are adhered to each other. The purpose is to provide.

In order to achieve the above object, the present invention
A sealing tag that is attached across the manhole cover and asphalt.
Consists of a base material made of caulking agent,
A part of the base material has entered the recesses existing on the surface of the asphalt in the region facing the asphalt.

In the present invention configured as described above, it is composed of a base material made of a caulking agent, and in a state where the base material itself is attached across the manhole cover and the asphalt, the base material itself is in a region facing the asphalt. Since a part of the recess is inserted in the recess existing on the surface of the asphalt, it is possible to prevent the region facing the asphalt from being easily peeled off from the asphalt.

Further, if the base material has a color-developing layer that develops color when the region of the base material is destroyed, at least in the region facing the boundary portion between the manhole cover and the asphalt, the manhole cover and the asphalt are used. When the area facing the boundary portion is destroyed and the manhole cover is opened, the color-developing layer develops color, and a trace of the attempt to open the manhole cover remains.

In addition, the above-mentioned sealing tag is
The process of applying caulking agent over the manhole cover and asphalt,
The step of laminating the color-developing layer on the applied caulking agent, and
It is conceivable that the product is manufactured by a step of applying a caulking agent so as to cover the color-developing layer.

According to the present invention, the base material is composed of a base material made of a caulking agent, and the base material partially penetrates into a recess existing on the surface of the asphalt in the region facing the asphalt, so that the base material straddles the manhole cover and the asphalt. It is possible to prevent it from being easily peeled off when it is attached.

Further, in the base material having a coloring layer that develops color when the region of the base material is destroyed, at least in the region facing the boundary portion between the manhole cover and the asphalt, the boundary between the manhole cover and the asphalt. When the area facing the portion is destroyed and the manhole cover is opened, the color-developing layer develops color, and a trace of the attempt to open the manhole cover can be left.

As shown in FIG. 1, the present embodiment is a sealing tag 1 attached across the manhole cover 3 and the asphalt 2 around the manhole cover 3 in a predetermined region of the outer periphery of the manhole cover 2, and is composed of a caulking agent. The color-developing layer 30 and the display member 20 are included in the base material 10.

As the caulking agent constituting the base material 10, one made of a modified silicone-based MS (Modified Silicone) polymer is preferable because it has excellent weather resistance, and when a curing medium is added, it reacts with water in the air at room temperature. A liquid polymer that becomes an elastic body can be used. Examples of such a caulking agent include Kaneka MS Polymer manufactured by Kaneka Corporation. Further, the caulking agent constituting the base material 10 is not limited to one made of a modified silicone-based MS (Modified Silicone) polymer, and may be a polyurethane-based one.

The color-developing layer 30 has an outer shape slightly smaller than that of the base material 10, so that when the sealing tag 1 is attached across the manhole cover 3 and the asphalt 2 around the manhole cover 3, the manhole cover 3 and the asphalt 2 are attached to each other. It is in a state of being arranged in the area facing the boundary portion.

As the color-developing layer 30, a well-known one that develops color when it is destroyed can be used. For example, we used an ink that is simply a sheet of pigment, and when the base material 10 is destroyed, the pigment oozes out from the destroyed portion, or an ink that develops color when exposed to the atmosphere. Things etc. can be considered. Further, the pigment or the like may be contained in the microcapsules, and in that case, the pigment or the like exudes to the outside due to the destruction of the microcapsules, resulting in color development. Further, it may consist of a mixture of microcapsules containing a color former and a color developer. In that case, the microcapsules are destroyed and the color developer mixes with the color developer to develop a color. It will be.

The display member 20 is a sheet-like material that is laminated on the color-developing layer 30 so as to be able to enter the date and the like on which the sealing tag 1 is attached across the manhole cover 3 and the asphalt 2. Is.

The sealing tag 1 configured as described above is attached across the manhole cover 3 and the asphalt 2 around the manhole cover 3, but as shown in FIG. 1 (b), in the region facing the asphalt 2 , A part of the base material 10 has entered the recess 2a existing on the surface of the asphalt 2.

Hereinafter, a method for manufacturing the sealing tag 1 configured as described above will be described.

When manufacturing the sealing tag 1 shown in FIG. 1, first, a frame member 4 having an outer shape of a base material 10 in a region of the manhole cover 3 and the asphalt 2 around the manhole cover 3 to which the sealing tag 1 is attached. Is arranged, and the caulking agent 10a is applied into the frame member 4 (FIG. 2A). As a result, the caulking agent 10a is applied over the manhole cover 3 and the asphalt 2 around the manhole cover 3. At that time, a number of recesses 2a are irregularly present on the surface of the asphalt 2, but the caulking agent 10a is in a liquid state and is in a state of entering the recesses 2a.

Next, the color-developing layer 30 and the display member 20 are sequentially laminated on the caulking agent 10a (FIGS. 2 (b) and 2 (c)).

Next, the caulking agent 10b is applied so as to cover the coloring layer 30 and the display member 20, and the caulking agent 10a and the caulking agent 10b are joined to form a base material 10 containing the coloring layer 30 and the display member 20. (Fig. 2 (d)).

After that, the frame member 4 is removed to complete the sealing tag 1 shown in FIG. The frame member 4 may have a sufficient height so that the applied caulking agents 10a and 10b do not flow out of the region to which the sealing tag 1 is attached, and a tape or the like is used. You may.

As described above, the sealing tag 1 of the present embodiment is not manufactured in advance before being attached across the manhole cover 3 and the asphalt 2, but is manufactured at the site where the sealing tag 1 is attached. be.

The operation of the sealing tag 1 manufactured as described above will be described below.

The sealing tag 1 manufactured as described above is composed of a base material 10 made of caulking agents 10a and 10b, and is attached to the base material 10 across the manhole cover 3 and the asphalt 2. Since a part of itself has entered the recess 2a existing on the surface of the asphalt 2 in the region facing the asphalt 2, it is avoided that the region facing the asphalt 2 is easily peeled off from the asphalt 2. It will be.

FIG. 3 is a diagram for explaining the action of the sealing tag 1 shown in FIG. 1 by the color-developing layer 30.

In a state where the sealing tag 1 is attached across the manhole cover 3 and the asphalt 2 around it as shown in FIG. 1, as shown in FIG. 3A, the manhole cover 3 is sealed in an attempt to open it. When the region of the stop tag 1 facing the boundary between the manhole cover 3 and the asphalt 2 is destroyed by cutting with a blade 5 such as a cutter knife, the coloring layer 30 contained in the base material 10 is destroyed. Color is developed, and as a result, the color-developing region 31 appears visibly from the outside as shown in FIG. 3 (b). Therefore, the color-developing region 31 makes it possible to leave a visible trace of opening the manhole cover 3.

FIG. 4 is a diagram for explaining a method of peeling the sealing tag 1 shown in FIG. 1 from the manhole cover 3 and the asphalt 2.

When the sealing tag 1 attached across the manhole cover 3 and the asphalt 2 is peeled off as described above, the base material 10 adheres to the manhole cover 3 and the asphalt 2 as shown in FIG. 4 (a). A blade 5 such as a cutter knife is inserted into the boundary between the surface and the surface of the manhole cover 3 or the asphalt 2, and the base material 10 is peeled off from the surface of the manhole cover 3 or the asphalt 2 as shown in FIG. 4 (b). As a result, the sealing tag 1 can be peeled off from the manhole cover 3 and the asphalt 2.

In this embodiment, the color-developing layer 30 has an outer shape slightly smaller than that of the base material 10, so that the sealing tag 1 is attached across the manhole cover 3 and the asphalt 2 around the manhole. Although it is in a state of being arranged in a region facing the boundary portion between the lid 3 and the asphalt 2, the coloring layer 30 is a region of the base material 10 facing at least the boundary portion between the manhole cover 3 and the asphalt 2. It suffices if it is placed in. Further, the display member 20 may be arranged so as to overlap only a part of the color-developing layer 30, or may be arranged side by side with the color-developing layer 30.

Further, of the base material 10 constituting the sealing tag 1 shown in FIG. 1, only the upper side of the coloring layer 30 and the display member 20 in the figure is sealed with the coloring layer 30 and the display member 20 laminated.
