Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a sealing device for coin storage bags and the like, and particularly to a sealing device having a tamper-proofing function.

BACKGROUND OF THE INVENTION The present inventor previously proposed a sealing device for a coin storage bag, etc., which is composed of a case having a hollow part, a string holding piece housed in the hollow part, and one string. He proposed a sealing device (see Japanese Patent Application Laid-Open No. 60-232589). The case of the sealing device proposed in the future is
Because it has a front wall and opens only at the rear, it is difficult to mold, and when assembling the seal, it is relatively difficult to insert the string into the case, making it difficult to work and making it difficult to manufacture. It wasn't easy.
In addition, since the string insertion holes formed on both sides of the front of the case are straight, if you insert a thin rod, etc. into the front end of the string insertion hole, the tip of the rod will easily reach the string presser protrusion, which could lead to unauthorized use. There was a problem that the package could be opened.

Purpose of the Invention The purpose of the present invention is to solve the above-mentioned problems, and to provide a case that is easy to mold, easy to assemble the components of the sealing device, good workability, and easy to manufacture. To provide a sealing device for a coin storage bag or the like that can prevent unauthorized opening.

Composition of the Invention In order to achieve the above object, the present invention has a rectangular cylindrical case with openings in the front and rear, a string holding protrusion on both left and right sides, and a case that is inserted from the rear opening of the case. In a sealing device equipped with a string holding piece fixed to a string and a string bent so as to be wrapped around an object to be sealed, such as a coin storage bag, a string is attached to both the left and right sides of the front end opening of a rectangular cylindrical case. A projecting wall projecting inward is provided, and a front wall that enters the center portion of the front end opening of the case is provided at the front of the string holding piece, and a projecting portion projecting to both left and right sides inside this wall is provided. Between the front projecting wall and left and right side walls of the case, and the front wall and left and right protrusions of the string holding piece, there is an L-shaped string insertion gap through which the left and right intermediate portions of the string are inserted. The gist is a sealing device such as a coin storage bag, which is characterized by the following:

String holding piece 4, string holding piece main body 12 made of ABC resin
and a string holding plate spring 13 made of a stainless steel plate.

The string holding piece main body 12 has a front wall 17 that enters the center part of the front end opening 6 of the case 3 at the front part thereof;
A protrusion 1 that protrudes on both left and right sides inside this
8 and 18 are provided, and a plate comprising, in the center thereof, spring tip rocking permitting recesses 21 and 21 on both left and right sides that are approximately triangular in shape when viewed from above, and an approximately inverted U-shaped groove 22 that communicates the two. A spring fitting recess 20 is provided. A substantially rectangular fitting convex portion 23 protruding downward is provided on the lower surface of the string presser main body 12.
Furthermore, stepped portions 27, 27 are provided on both the left and right sides of the rear end, respectively. A circular recess 29 is provided on the rear central lower surface of the string holding piece main body 12 for receiving a coupling protrusion 28 knocked out from the lower wall of the case 3.

The string-holding leaf spring 13 consists of a roughly U-shaped bent front end 24 at the center and string-holding protrusions 14, 14 extending obliquely backward from both ends of the bent front end 24, and has a roughly inverted Y shape when viewed from above. are doing.

The string holding piece 4 holding the leaf spring 13 is inserted from the rear end opening 7 of the case 3 and fixed to the case 3, thereby allowing the front projecting walls 8, 8 and both left and right side walls of the case 3 to be fixed. 9, 9 and the front wall 17 and protrusions 18, 18 of the string holding piece main body 12, L-shaped bent string insertion gaps 30, 30 are formed, respectively.

One string 5 is folded back at approximately the center of the required length, and the folded portion 5a is hung on the rear surface of the lower wall of the case, and the string portion 15 on one side of the folded portion 5a is attached to the same side of the case 3. It passes through the lower string insertion hole 11 and is taken out from its front end to form a first ring-shaped part 16 for drawing the sealed object, and the middle part 15a of the string part 15 is bent on the opposite side from the front part of the case 3. The end portion 15b of the cord passes through the cord insertion gap 30 and the outside of the cord presser protrusion 14, and is taken out from the rear of the case 3. In addition, the string portion 25 on the other side of the sealing tool 5a passes through the lower string insertion hole 11 on the same side of the case 3 and is taken out from its front end to form a second ring-shaped portion 26 for drawing the object to be sealed. The middle part 25a of the string part 25 passes through the bent string insertion gap 30 on the opposite side of the front part of the case 3, and then passes through the outside of the other string presser protrusion 14, and the tip part 25b of the string part 25 passes from the rear part of the case 3. It is taken outside.

At the front ends of the case 3 and the string holding piece 4, string locking protrusions 31 and 32 are provided which are aligned with each other and have an arcuate cross section. This is to reduce the contact area between the coin storage bag 2 and the case 3 in the sealed state, thereby preventing the string 5 from loosening due to the case 3 swinging up and down. Therefore, such a protrusion 31,
32 does not have to have an arcuate cross section, but may have a substantially triangular shape, for example, and the case 3 and the string holding piece 4
The front end itself may have an arcuate or triangular cross-sectional shape.

The above-mentioned sealing tools are combined, for example, in the following manner. First, one string 5 of the required length is folded back at approximately the center, the folded part 5a is hung on the rear surface of the lower wall of the case 3, and the string part 15 on one side of the folded part 5a is attached to the lower part of the same side of the case 3. The string portion 25 at the other end is taken out from the front end through the lower string insertion hole 11 on the same side. Then, the end portions 15b, 25b of these string portions 15, 25 are joined to each other by fusion in a state in which they are juxtaposed horizontally or vertically. Next, twist the string portions 15 and 25 once so that they intersect in an X shape, and pass the connected end portions 15b and 25b of the string 5 into the case 3 through the front end opening 6 of the case 3, and Take it out from the opening 7. As a result, the first ring-shaped part 16 and the second ring-shaped part 26 for drawing the object to be sealed are formed in the front of the case 3. In this case, since both ends 15b and 25b of the connected string 5 are inserted into the case 3 and taken out, the work is very simple. Then, the leaf spring 1 is inserted through the rear end opening 7 of the case 3.
Insert the string presser piece 4 having the number 3. At this time, since the downward fitting convex portion 23 of the string holding piece 4 is fixedly guided by the guide groove 19, the operation of inserting the string holding piece 4 is extremely smooth and accurate. The downward fitting protrusion 23 is the guide groove 1
9, that is, the state in which the string presser piece body 1 is in contact with the front end.
With the front wall 17 of the case 3 inserted into the approximately central portion of the front end opening 6 of the case 3, a predetermined knock-out type joining device presses and heats a predetermined portion of the lower wall of the case 3 to separate the string presser piece body. The sealing tool 1 is manufactured by connecting the string holding piece 4 to the case 3 by punching it out slightly on the 12 side and fitting the protrusion 28 into the circular recess 29.

The coin storage bag 2 is sealed by the sealing tool 1 in the following manner.

That is, the first ring-shaped part 16 and the second ring-shaped part 26 of the string 5 of the sealing tool 1 are connected to each other through the case 3 as if they were two rings.
These first and second rings form a heavy ring.
The opening of the coin storage bag 2 is fitted into the ring-shaped parts 16 and 26, and in this state, both ends 15b and 25b of the string 5 on the outside of the rear part of the case 3 are pulled. Then,
The sizes of the first and second annular parts 16, 26 are both reduced, and the opening of the coin storage bag 2 is narrowed by these annular parts 16, 26, so that both the annular parts 16,
When the string 26 is most tightened, the required intermediate portions 15a, 25a of the string 5 are firmly held down by the string pressing protrusions 14, 14 of the string pressing piece 4. In this state, the string 5 can no longer be pulled out to the coin storage bag 2 side, and the sealing of the bag 2 is completed.

In the sealed state, even if a thin rod or the like is inserted from the front end of the string insertion gap 30 of the sealing device 1, the gap 30
Since it is bent, hold the tip of the thin rod with the string holding protrusion 1.
4, it cannot be inserted deeply, and unauthorized opening can be prevented. Strap presser projections 14, 14
extends diagonally backward, so it is difficult to open the seal from the rear side of the seal 1.
Even if you insert a thin rod from one side of the rear end opening 7,
In this embodiment, step portions 10 and 27 are provided on the side wall 9 of the case 3 and the side portions of the string holding piece main body 12, respectively, so that the thin rod cannot be inserted too deeply and unauthorized opening can be prevented.

FIG. 6 shows a second embodiment of the invention. Here, the difference from the first embodiment is that the front end 2 of the leaf spring 13 attached to the string holding piece 4 is
4 is thinly bent like a hairpin, the shape of the leaf spring 13 is different, there is no insertion hole in the lower part of the case 3, and the string 5 forms a single ring-shaped part 16. The two points are that the string is folded as shown in FIG.

7 to 11 show a third embodiment of the present invention. Here, the difference from the first embodiment is that the string holding piece 4 is made of a synthetic resin molded product such as Jyuracon, and the string holding piece 4
The strap presser protrusions 14, 14 are integrally provided on both the left and right sides.

The other points of the above two embodiments and the third embodiment are the same as those of the above first embodiment, so the same parts are given the same reference numerals in the drawings.

In each of the above embodiments, the looped portions 16 and 26 of the string 5 are wrapped around the opening of the coin storage bag 2 only once, but these looped portions 16 and 26 may be wrapped around the opening of the coin storage bag 2 two or more times. It can also be sealed.

Further, in the above embodiment, a case was shown in which a bank coin storage bag 2 was sealed with the sealing tool 1 of the present invention, but the sealing tool 1 of the present invention is not limited to this. It can be used to seal various things.
