DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin sealing device used for sealing a certified measuring instrument such as a taxi meter.

[0002]

2. Description of the Related Art Meters such as taxi meters are provided with a cover for the meter so that the meter cannot be readjusted after being adjusted and verified in order to ensure that the indicated value of the meter is accurate. It is sealed.

Conventionally, this sealing is performed by using a wire such as a copper wire and a sealing member such as lead or brazing to form a loop between the lid and the body with a wire so that the lid is hardly opened. And
The connection portion is fixed by a seal member, and a unique mark held by an inspection organization or a guarantor is pressed on the seal member portion.

In order to release the sealing, it is necessary to cut the wire such as the copper wire or to peel off the sealing member such as lead at the connection portion to release the connection. Therefore, the wire portion and the seal with the stamp are required. If there is no damage to the member and this is sound, it can be considered that this seal has not been opened.

[0005] That is, the sealing and engraving provide evidence that the sealed portion has been released so that the fact that the sealed portion is released becomes clear when the sealed portion is released.

[0006] Such a sealing is used in addition to various meters, and a cash bag for transportation, a container for transportation, and the like are similarly sealed.

In Japanese Unexamined Patent Publication No. 10-101111, an elastically deformable filament portion 1 as shown in FIG. 16 is provided at both ends with a socket portion 2 having a tab T and an insertion hole 2b of the socket portion 2. A sealing device 10 made of synthetic resin provided with an engaging head 4 to be fitted has been proposed. When this sealing device 10 is used, as shown in FIG. The sealing operation can be performed extremely simply by inserting the portion 4 into the insertion hole 2b of the socket portion 2. Then, a tab T protruding from the socket portion 2 is stamped.

[0008]

However, in these sealings, the manual operation of forming a loop with a wire such as a copper wire and a sealing member such as lead is troublesome, and if the attention is distracted, the sealing member cannot be used. The wire is held at the end, and the wire may be dislodged from the sealing member with a small force.
There is a problem that it is not possible to perform 00% reliable sealing.

In particular, when the sealing operation is performed halfway and the sealing is incomplete, it is necessary to determine whether the wire has come off due to a sealing error or intentionally unsealing. This makes it difficult to provide a proof of opening, so that the sealing function cannot be performed.

In the sealing device disclosed in Japanese Patent Application Laid-Open No. 10-101111, the size of the loop formed by the engagement between the engagement head 4 and the socket portion 2 is constant, and the tip of the filament portion 1 is formed. Since the engaging head 4 is formed at the bottom, a small loop cannot be formed. for that reason,
There is a problem that the sealing of the taximeter cannot be used for sealing such a small portion because a sufficient margin for opening the lid arises, so that the sealing cannot be performed sufficiently.

SUMMARY OF THE INVENTION The present invention has been made in order to solve such a problem, and an object of the present invention is to make it possible to easily perform a sealing operation for forming a minimum loop, and to determine whether or not sealing has been performed securely. It is an object of the present invention to provide a sealing device that can easily determine the position of the user and can easily display the identification mark.

[0012]

The sealing device of the present invention for achieving the above object is constituted as follows.

Consisting of an engagement through hole having a piece, wherein the locking band portion is
A locking portion that can be inserted into the engaging through-hole in the insertion direction and that is immovable by engaging with the engaging piece in the direction opposite to the insertion direction so as to be immovable. It is formed by arranging a plurality of pieces in the longitudinal direction.

The engaging through hole is formed to have an opening at a portion near the upper end surface such as the upper end surface or the side end surface of the main body, and the opening at the outlet side is inserted into the opening at the inlet side. The locking band portion is formed so as to be smoothly inserted therethrough. In addition, the relative position between the connection portion of the locking band portion and the engagement through hole is easier to insert when parallel, but may be inclined, and is not limited to the parallel state.

According to this configuration, the engaging teeth are sequentially engaged with the engaging through-holes by inserting the locking band portion in which a plurality of engaging teeth are arranged in the engaging through-hole and pulling the tip. By engaging the stop, a minimum loop can be easily formed and fixed.

Since the locking band portion is formed in a band shape, it can have a larger cross-sectional area and a higher tensile strength than a filamentous band portion. Therefore, even when the entire sealing device and the locking band are formed small so as to be used for sealing a small portion, there is no risk of breakage when the tip of the locking band is pulled to reduce the loop.

Further, since the locking band portion has a band shape, it is easy to hold, and the band portion at the tip end and the flat band portion spreading on both side surfaces of the engaging teeth serve as a guide, so that the band is inserted into the engaging through hole. easy.

By simply inserting the locking band into the engaging through-hole, a loop can be reliably formed, halfway engagement is eliminated, and this loop has an engaging piece with an engaging tooth. Since the loop is formed by meshing, once the loop is formed, the loop cannot be released unless the engaging teeth of the locking band portion or the locking piece of the engaging through hole is damaged. Is released, the trace remains.

Further, since an engaging through-hole having a locking piece is provided on a side portion of the main body and can be formed separately from the locking band portion,
The size of the main body can be relatively large, and the sign display portion can be formed in a required size.

2) In the above-mentioned sealing device, the sign display portion is formed of an aggregate of minute projections, and the minute projections are crushed by pressing, and have a gloss different from that of the background that has not been crushed. Form.

The size of the fine projection is 0.1 mmφ in diameter.
~ 0.3mmφ, preferably 0.2mmφ, height 0.1mm ~ 0.4mm, preferably 0.25mm,
The adjacent distance is 0.05 mm to 0.15 mm, preferably 0.1 mm.

According to this configuration, since the marker display portion for displaying a seal or the like is formed by the minute projections, when the stamp is pressed, the pressed minute projections are damaged and formed by the unbreakable minute projections. An engraved mark is displayed by a group of crushed microprojections emitting gloss different from the background to be performed.

3) In the above-mentioned sealing device, the minute projections of the sign display portion are formed of a material which causes a whitening phenomenon when crushed.

According to this configuration, when a synthetic resin (plastic) product is subjected to a strong stress, the portion becomes white due to a whitening phenomenon, and the crushed portion of the minute projection is whitened. Easier to do. The whitening phenomenon can be further easily caused by mixing a whitening filler.

4) In the above sealing device, a fragile portion which can be broken by a manual operation is provided near the connecting portion of the locking band portion with the main body.

The fragile portion has a tensile strength equal to or higher than that of the other portions, but is vulnerable to bending or twisting, and is a flat member or a band portion having a plurality of narrow columns or perforations. Etc., which can be cut only by manual operation without using a cutter such as scissors or pliers.

Since the sealing device is provided with the fragile portion, the sealing can be easily released without using tools such as scissors and pliers, so that the work efficiency when releasing the sealing is remarkably improved. I do.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a closure according to the present invention.

First Embodiment As shown in FIGS. 1 to 8, a closure 20 according to a first embodiment of the present invention is integrally formed of a synthetic resin such as nylon, low-density polyethylene, or polypropylene. A plate-shaped main body 21 having a sign display surface 22, a locking band 23 having one end connected to an upper end surface 21u of the main body 21, and one end side 25 connected to the upper end surface 21u.
u is open and the other end 25d is open downward.
And an engagement through hole 25 having

The locking band 23 has locking teeth 24.
Are arranged continuously in the longitudinal direction and are provided in a sawtooth shape. The locking teeth 24 are formed so as to be able to be inserted into the engagement through holes 25 in the insertion direction A, but in a direction B opposite to the insertion direction A.
In FIG. 8, as shown in FIG. 8, the front end is formed by an inclined surface 24a and a rear end by a vertical surface 24b so as not to move by engaging with the engaging piece 26.

If the locking teeth 24 are provided on the front and back sides instead of the side portions of the locking band 23, the locking teeth 24 can be formed large, and the locking band 23 can be formed on the side of the band. Since it is difficult to bend, it is easy to bend to the front and back sides of the band, and the bending direction is determined, it is very easy to operate when the locking band portion 23 is bent and inserted into the engagement through hole 25.

The sign display portion 22 formed on the surface of the main body 21 is formed by an aggregate of minute projections 22p which are crushed by the pressing at the time of engraving and have a gloss different from the background which is not crushed, The sign display unit 22 is formed by the minute projections 22p.
Cover.

The minute projection 22p has a diameter of 0.1 mmφ.
~ 0.3mmφ, preferably 0.2mmφ, height 0.1mm ~ 0.4mm, preferably 0.25mm,
The adjacent distance is 0.05 mm to 0.15 mm, preferably 0.1 mm.

Further, the sealing device 20 is made of a material which causes a whitening phenomenon, for example, a synthetic resin such as polypropylene, so that the minute projections 22p of the sign display portion 22 may cause the whitening phenomenon of the plastic due to the crush. In addition, the minute projection 2
Since the 2p portion only needs to be whitened, if possible, it may be formed of a material which is easily whitened partially, or a filler for whitening may be added.

The entrance side opening 25 of the engagement through hole 25
The cast-through prevention holes 27 are provided on both sides of u to prevent deformation of the engagement through-hole 25 due to solidification and shrinkage, and secure dimensional accuracy of the engagement through-hole 25.

The engaging through-hole 25 does not necessarily need to have an opening at the upper end surface 21u to which the locking band portion 23 is connected, and the opening is formed at the side end surface, for example, in the horizontal direction in FIG. May be provided with an engagement through hole 25, or an opening may be formed at the side end surface and the lower end surface, and the engagement through hole 25 may be provided at an angle, or provided at a part of a plate-shaped main body. I just need.

According to the sealing device 20 having the above-described configuration, the locking band portion 23 in which a plurality of engaging teeth 24 are arranged in a sawtooth shape is inserted into the engaging through-hole 25 having the locking piece 26 and the tip is pulled. Thereby, the engaging teeth 24 are sequentially engaged with the locking pieces 26 of the engaging through-holes 25, so that the loop can be easily formed into a required minimum loop state and sealed.

Then, the locking band portion 23 is connected to the engaging through hole 2.
Since the loop can be reliably formed only by passing through the loop 5, the halfway engagement state can be avoided and the sealing can be surely performed. At the same time, once the loop is formed, this loop cannot be released unless the engaging teeth 24 of the engaging band portion 23 or the engaging piece 26 of the engaging through hole 25 is damaged, and thus the loop is incorrectly released. In some cases, its traces remain.

The locking band 23 is connected to the upper end face 21u of the main body 21, and the engaging through hole 25 is also provided in the upper end face 21u. It can be formed large if necessary, and the loop becomes U-shaped, so that the sign display section 22 can be reliably held at a position where it can be easily seen. Therefore, it looks good.

Further, the sign display section 22 is provided with a minute projection 22p.
Since the small projections 22p are pressed by the projections of the stamp when the stamp is pressed, the stamps are displayed by the unevenness of the minute projections 22p.

Further, if the minute projections 22p of the sign display portion 22 are formed of a material that causes a whitening phenomenon when crushed, the crushed portions of the minute projections are whitened when the stamp is pressed and pressed, and the stamp is raised to white. It will be easier.

[Second Embodiment] Next, FIGS.
A sealer 20A according to a second embodiment of the present invention shown in FIG.

The closure 20A of the second embodiment is
The difference is that the sign display surface 22A is not formed of a group of minute projections, and that a fragile portion 28A that can be broken manually is provided near the connecting portion of the locking band portion 23A with the main body 21A. Is the same.

When the sign display surface 22A is formed as a flat surface, it is difficult to stamp the stamp by pressing, but it is possible to give a sign by printing or a seal.

The fragile portion 28A has a tensile strength substantially equal to or higher than that of the other portions of the locking band portion and the engagement of the engaging portion, but is weak against bending and twisting. , Which are formed so that they can be cut only by manual operation without using a cutter such as scissors or pliers.

In the closure 20A of the second embodiment, the fragile portion 28A is provided with a base 28a on the upper end surface 21Au of the main body 21A as shown in FIG. 15, and the base 28a has a flat member 28b and a narrow member on both sides. Pillars 28c are erected to support a lower cylindrical portion 23Aa on the lower side of the locking band 23A and a supporting portion 28d formed in a triangular shape from the side surface of the cylindrical portion 23Aa.

When holding the main body 21A by hand and holding the base of the locking band portion 23A with another hand and twisting the portion, first,
The narrow column 28c is damaged, and the flat member 28b is damaged,
8A is disconnected.

According to the sealing device 20A having the above structure, since the fragile portion 28A is provided, the sealing can be easily opened without using tools such as scissors and pliers, and the working efficiency is remarkably improved. Can be improved.

[0049]

As is clear from the above description, according to the closure of the present invention, the following effects can be obtained.

1) The locking band can be inserted into the engaging through-hole in the insertion direction in the inserting direction, and cannot be moved by engaging with the engaging piece of the engaging through-hole in the direction opposite to the inserting direction. Since a plurality of locking portions are provided in the longitudinal direction of the locking band portion, the locking band portion in which the engagement teeth are arranged in a saw blade shape is inserted into the engagement through hole, and the tip is pulled, The minimum teeth can be easily formed and sealed by sequentially engaging the engagement teeth with the engagement pieces of the engagement through holes. Therefore, the loop can be reliably formed only by inserting the locking band into the engagement through hole.

Since the locking band is formed in a belt shape, it can have a larger cross-sectional area and a higher tensile strength than a filament-shaped one, and can be used for sealing small parts for use in measuring instruments such as taxi meters. In this case, it is possible to eliminate the possibility of breakage when the loop is reduced by pulling the tip of the locking band.

Further, since the locking band portion has a band shape, it is easy to hold, and the band portion at the tip and the flat band portion spreading on both sides of the engaging teeth serve as a guide, so that it is easy to insert into the engaging through hole. .

2) Further, since the sign display portion for displaying a seal or the like is formed by a group of minute projections, the minute projections pressed when the stamp is pressed are damaged. By generating irregularities on the minute projection group, the engraved mark can be clearly displayed.

3) By forming the minute projections of the sign display portion from a material which causes a whitening phenomenon when crushed, the crushed portions of the minute projections are whitened and the markings are raised to white, so that the identification is facilitated. Can be.

4) Further, by forming a fragile portion which can be broken by hand in the vicinity of the connection portion of the locking band portion with the main body, the sealing can be easily performed without using tools such as scissors and pliers. The work efficiency can be remarkably improved.
