A detent protrusion standby recess 22 into which the detent protrusion 18 is fitted, and a detent protrusion latching recess 21 on the front side thereof are provided. The inner walls of the left and right rising portions 33 and 34 of the lower half body 3b constitute the left and right side walls 7 and 8 of the hollow portion 6 of the case 3, and a string release notch is provided at the upper inner side of the front part of the lower half body 3b. 14, 14 are provided, respectively. The string loosening prevention protrusion 37 is provided on the lower half body 3b.

The upper half 3a is connected to the lower half 3b, and the left and right hanging parts 2 are attached to the outside of these left and right rising parts 33 and 34.
When combined so that 9 and 30 are positioned, a hollow part 6 is formed between the upper half body 3a and the lower half body 3b, and string insertion holes communicating with the front end of the hollow part 6 are provided on both sides of the front wall 35. 27, 27 are formed. In addition, the rear wall 31 of the upper half 3a has both left and right rising portions 33,3.
Cord insertion holes 28, 28 are formed between the rear wall 31 and the rising portions 33, 34 to communicate with the rear end of the hollow portion 6. The left and right side walls of the case 3 are constituted by the hanging portions, the rising portions 29, 33, and 30, 34.

Between the upper half body 3a and the lower half body 3b, there is a cord presser piece 4, that is, a cord presser main body 9 and a presser member 11.
and one string 5 are assembled as shown in FIG.
The upper half body 3a and the lower half body 3b are integrally joined by fusing the lower walls of both the left and right hanging parts 29, 30 of a and the left and right side edges of the upper wall of the lower half body 3b. Then, a case 3 is formed, and a sealing tool 1 is produced in which a string presser piece 4, a pair of wedges 50, 50, and a string 5 are assembled in a predetermined arrangement.

For example, the sealing tool 1 has a length of 2 cm, a width of 1.6 cm,
It is small, about 0.6 cm thick, and how to use it will be explained below.

In the state before sealing of the sealing tool 1, as shown in FIGS. 1 to 3, the string holding piece 4 is arranged at the rear inside the case 3, and the detent protrusion 18 of the string holding piece 4 is hollow. The seal state display projection 43 is fitted into the standby recess 22 of the lower wall 20 of the portion 6 , and is pressed into the case 3 against the elastic force of the support member 42 . The first ring-shaped part 16 and the second ring-shaped part 2 of the string 5
6 forms a double ring with case 3 in between.

And these first and second annular portions 16, 2
Insert the opening of the coin storage bag 2 into the inside of the coin storage bag 6, and in this state, insert both ends 15 of the string 5 on the outside of the rear of the case 3.
c, pull 25c. Then, the first and second
The sizes of the ring-shaped parts 16, 26 are both reduced, and the opening of the coin storage bag 2 is tightened by these ring-shaped parts 16, 26, and when both the ring-shaped parts 16, 26 are tightened the most, As shown in FIGS. 4 to 6, the string holding piece 4 is moved forward together with the string folded portion 5a.

As the string presser piece 4 moves forward, the required intermediate portions 15b, 25b of the string 5 are firmly held down by the string presser protrusions 13, 13 made of metal strips of the string presser piece 4, and the string presser piece 4 detent protrusion 18
is pressed inward together with the thin-walled portion 17 by the elasticity of the thin-walled portion 17, and then the detent protrusion 18 is fitted into the latching recess 21 and latched to the rear wall of the recess 21. , the string presser piece 4 is prevented from retreating, and the sealing of the coin storage bag 2 is completed.
At the same time, the sealing state display projection 43 fits into the window 44 of the case 3 due to the elastic force of the support member 42, thereby allowing the sealing state to be determined from the outside.

Note that the first and second ring-shaped portions 16 and 26 of the string 5
is wrapped around the opening of the coin storage bag 2 only once in the figure, but these looped parts 16, 2
6 can also be wrapped twice or more to seal.

Further, in the above embodiment, the sealing state displaying protrusion 43 is attached to the string presser piece 4 via the L-shaped support member 42 with a transverse surface. It may be attached to the holding piece 4, and the shape of the projection 43 is arbitrary.

Further, in the above embodiment, the case 3 is composed of an upper half body 3a and a lower half body 3b, which are integrally joined to each other by fusion.
Of course, the upper half body 3a and the lower half body 3b may be joined by so-called adhesion or welding. In addition, the case 3 can also be made by integral molding. Further, although the illustrated case 3 has a box shape, it may of course have a cylindrical shape, a truncated cone shape, or the like. String 5
is made of nylon, for example, but it may of course be made of other synthetic fibers or materials such as hemp. Alternatively, a knot may be provided at the center of the required length of the string 5, and the knot may be hung on the rear wall of the string holding piece 4.

The reason why one string 5 is used in a folded state as described above is because it is convenient when hooking the string 5 to the string presser piece 4. Therefore, for example 2
By using strings that are approximately the same length as the book, one end of each is fixed to the string holding piece 4, and the two ring-shaped parts 16 and 26 are formed by these two strings.
Of course, this invention may be implemented. In this case, the strings 5 are connected together via the string presser piece 4, but it is somewhat troublesome to separately fix one end of each of the two strings 5 to the string presser piece 4. be.

Further, in the above embodiment, the string presser protrusions 1 are provided on both the left and right sides.
3 and 13 is made from one metal strip, but it may also be made from two metal strips, for example, by cutting the central part of the bent portion 12. good. The shape of the string presser protrusions 13, 13 is not limited to that shown in the drawings, and may be any suitable shape.

In addition, the string 5 shown in the figure has predetermined portions including string insertion holes 27, 27 formed on both left and right sides of the front wall 35 of the case 3, and string insertion holes 28, 28 formed on both left and right sides of the rear wall 31. In addition, string insertion holes are made in the front and rear parts of the case 3 that pass through both the upper and lower walls or the left and right sides of the case 3, and the string 5 is taken out from these holes. A predetermined portion may be taken out to the outside.

Furthermore, in each of the above embodiments, the coin storage bag 2 is sealed using the sealing tool 1 of the present invention.
The sealing device 1 of the present invention is not limited to this, and can also be used to seal various other items.

As described above, the sealing tool 1 according to the present invention is composed of the case 3, the string holding piece 4 housed in the middle part 6 of the case 3, and one string 5, and the string holding piece 4 is It is composed of a string presser body 9 made of synthetic resin, and a metal presser member 11 which is combined with the string presser body 9 and has string presser protrusions 13, 13 on both sides that project from the main body 9 to the left and right sides. In the sealed state, the middle parts 15b, 25b of the string 5 are firmly held down by the strong metal string presser protrusions 13, 13, so the string 5 does not loosen at all. , it is possible to achieve a complete seal. Moreover, such a string presser protrusion 13,
Since the holding member 11 having the holding member 13 is made of a metal with high strength, the main body 9 for holding the string holding member 13 can be made of an inexpensive synthetic resin with relatively low strength, and the shape of the main body 9 is also simple. Therefore, the material cost is reduced accordingly, and the mold manufacturing cost of the main body 9 is also reduced, which has the effect of reducing the manufacturing cost of the sealing tool.
