Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sealing device such as a coin storage bag.

The present inventor previously proposed a sealing device of this type that was composed of a case having a hollow part, a string holding piece housed in the hollow part, and a single string. (See Japanese Patent Application No. 1985-11985). The previously proposed sealing device is designed by inserting the opening of the coin storage bag into the ring-shaped part of the string formed twice through the case, and by pulling both ends of the string, the opening of the bag can be inserted into the ring-shaped part of the string. The coin storage bag is tightened by the string, and the middle part of the string is held down by the string pressing piece inside the case, making it very convenient to seal the coin storage bag very easily. However, the previously proposed sealing device had a problem in that it was difficult for general users to determine the sealing state, so they did not know to what extent the string should be tightened, and there was a risk that a perfect seal could not be achieved.

The object of the present invention is to solve the above-mentioned problems and provide a sealing tool that allows even general users to easily determine the sealing state, and therefore always achieves a perfect seal.

This invention will be explained below based on embodiments shown in the drawings.

In this specification, front and back, left and right, and top and bottom are based on FIG. 1, and front means the upper side of FIG.
"Rear" refers to the bottom side of the drawing, "left" refers to the left side of the drawing, "right" refers to the right side of the drawing, and "top" refers to the front side of the drawing sheet.
Bottom means the same back side.

In the drawing, a sealing tool 1 for sealing a coin storage bag 2, etc. is a small box-shaped case 3 made of synthetic resin having a hollow part 6, and a synthetic resin such as Diuracon housed in the hollow part 6. Made of string presser piece 4
For example, a string 5 made of nylon round string.
It is composed of: Hollow part 6 of case 3
The left and right side walls 7, 8 are inclined inward toward the front.

The string holding piece 4 has a substantially truncated triangular shape when viewed from above, and four string holding protrusions 13 are provided on the left and right side walls 11 and 12 of the piece, each having a relatively long shape in the shape of a fish's spine when viewed from above. It is being Further, a slit 14 notched in the width direction of the string holding piece 4 is provided at the rear of the string holding piece 4, a thin walled portion 17 is formed below the slit 14, and a detent protrusion is formed at the tip of this thin walled portion 17. A section 18 is provided. Correspondingly, two latching recesses 21 into which the detent protrusions 18 are fitted are provided at predetermined locations on the lower wall 20 of the hollow portion 6 of the case 3, and one detent protrusion on the rear side thereof. A standby recess 22 is provided. Here, the bottom wall of the standby recess 22 is flat, but the latching recess 2
The bottom wall of No. 1 is inclined upward toward the front. Two latching recesses 21 are arranged consecutively, and the detent protrusion 18 is sealed by fitting into the first latching recess 21.
Furthermore, even if the string 5 is pulled with a force stronger than this, the string presser piece 4 can move forward.

A sealing state display projection 43 is provided on the upper wall 40 of the string holding piece 4 and is urged outward by an inverted U-shaped support member 42 when viewed from the elastic side. And case 3 on the same side as this protrusion 43

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 48 does not have to have an arcuate cross section, but may have a substantially triangular shape, for example, and the front end of the case 3 itself may have an arcuate or triangular cross section. It may be something that you have.

The case 3 is made of synthetic resin such as ABS, and as shown in FIGS. 3 to 7, an upper half 3a and a lower half 3b formed by a mold are integrated by fusion. It is created by doing.
The upper half 3a has a rectangular shape when viewed from above, and has drooping parts 29 and 30 on both left and right edges of the upper half 3a, and a rear wall 31 on the rear end thereof. Rear wall 31 and left and right hanging parts 29,3
A gap 32, 32 of a required width is provided between the rear end portion of 0 and the rear end portion of 0, respectively. The lower half 3b is the upper half 3

Between the front wall 35 and the front end portions of the left and right rising portions 33, 34, gaps 36, 36 having a width through which 52 strings can be inserted are formed in an inverted C shape when viewed from above. Also lower body 3
The upper wall of b is the hollow part 6 of the case 3 after assembly.
The upper wall of the lower half 3b has a recess 22 in which the detent protrusion 18 of the string presser piece 4 is fitted, and a detent protrusion standby recess 22 for fitting the detent protrusion 18 of the string holding piece 4 thereinto. Concave part 2 for latching the detent protrusion on the front side of

When the upper half 3a is combined with the lower half 3b so that the left and right hanging parts 29, 30 are located outside of the left and right rising parts 33, 34, the upper half 3a and the lower half 3b are combined. A hollow part 6 is formed therebetween, and string insertion holes 27, 27 are formed on both sides of the front wall 35 to communicate with the front end of the hollow part 6. Further, the rear wall 31 of the upper half body 3a has both left and right rising portions 3.
3 and 34, and the rear wall 31
Strap insertion holes 28, 28 communicating with the rear end of the intermediate portion 6 are formed between the two rising portions 33, 34.
And the hanging part and the rising part 29, 33 and 30, 3
4 constitute the left and right side walls of the case 3.

After the string presser piece 4 and one string 5 are assembled between the upper half body 3a and the lower half body 3b as shown in FIG. The upper half 3a and the lower half 3b are integrally joined by welding the lower walls of the left and right hanging parts 29, 30 and the left and right edges of the upper wall of the lower half 3b to each other. , case 3 is formed, case 3
A sealing tool 1 is produced in which a string presser piece 4 and a string 5 are incorporated 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 and 2, the string presser piece 4 is arranged at the rear inside the case 3, and the detent protrusion 18 of the string presser piece 4 is hollow. The sealed 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 case 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. 11 and 12, the string holding piece 4 is moved forward together with the string folded portion 5a, and the desired intermediate portions 15b, 2 of the string 5 are moved forward.
5b is sandwiched between the left and right side walls 11, 12 of the string presser piece 4 and the left and right side walls 7, 8 of the hollow part 6 and is held down by the string presser protrusions 13, 13, and the string presser piece 4 After the detent protrusion 18 is pressed inward together with the thin part 17 by the elasticity of the thin part 17, the detent protrusion 18 is pushed into the latching recess 21.
By being fitted into the recess 21 and hanging on the rear wall of the recess 21, the string holding piece 4 is prevented from retreating.
The sealing of 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. In addition, in this state, the string 5
Because the knot 23 enters the lower side of the protrusion 43,
The protrusion 43 is further pushed up by the knot 23, so even if the protrusion 43 fitted in the display window 44 is pushed down a little from the outside, the case 3
Don't go inside.

In addition, in this embodiment, the string presser protrusions 13, 13
Since these protrusions extend relatively long on both the left and right sides of the string presser piece 4, these protrusions 13, 13 are bent slightly as the string presser piece 4 moves forward, and the string 15 is firmly held against the left and right side walls 7, 8. The restoring force of these protrusions 13, 13 increases the string 15.
Therefore, even if one string intermediate portion 25 is pulled from the bag 2 side in the sealed state, the string 5 will never loosen and a perfect seal can be achieved. Although the first and second ring-shaped parts 16 and 26 of the string 5 are wound around the opening of the coin storage bag 2 only once in the illustrated example, these ring-shaped parts 16 and 26 can be wrapped around the opening of the coin storage bag 2 twice or more. It can also be wrapped and sealed.

In the above embodiment, the sealing state displaying protrusion 43 is attached to the string holding piece 4 via the support member 42 having a U-shape with a lateral surface. It may be attached to the holding piece 4, and the shape of the projection 43 is arbitrary. The protrusion 43 is provided on the upper wall 40 of the string holding piece 4;
1, in which case the detent protrusion 18 may be provided on the upper wall 40, or may be omitted in some cases. Of course, the display window 44 is provided on the upper wall 19 or the lower wall 20 of the case 3 in correspondence with the projection 43.

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, but the upper half body 3a and the lower half body 3b Of course, they may be joined by so-called adhesion or welding. In addition, the case 3 can also be made by integral molding. Furthermore, although the illustrated case 3 has a box shape, it may of course have a cylindrical shape, a truncated cone shape, or the like. Although the case 3 and the string holding piece 4 are made of synthetic resin, they may be made of other materials. The string 5 is made of nylon, for example, but may of course be made of other synthetic fibers or materials such as hemp. Further, although a knot 23 is provided at the center of the required length of the string 5, this may be omitted. In that case, it is preferable to fix the folded portion 5a of the string 5 to the string presser piece 4 by adhesive or the like, but since the string 5 is difficult to shift from side to side during sealing work, simply attach the folded portion 5a of the string 5 to the string presser piece 4. Alternatively, the folded portion 5a may be fitted into a fitting groove provided in the string holding piece 4.

Further, in the above embodiment, four string presser protrusions 13, 13 are provided on each of the left and right side walls 11, 12 of the string presser piece 4;
It is sufficient that at least one is provided for each
Also, on both the left and right sides of the string presser piece 4, the left and right side walls 7, 8 of the hollow part 6 and the left and right side walls 1 of the string presser piece 4.
It suffices if it is provided in either one of 1 and 12. 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, in the embodiment, a thin wall portion 17 and a detent protrusion 18 are provided on the lower rear side of the string presser piece 4, but these are located on both upper and lower sides of the front part of the string presser piece 4 and on both upper and lower sides of the rear part of the string presser piece 4. , it suffices if it is provided in at least one location. Of course, corresponding to the detent protrusions 18 provided on these string holding pieces 4, detent protrusion latching recesses 21 are provided at predetermined locations on both upper and lower side walls 19, 20 of the hollow portion 6 of the case 3. . In addition, although there are two latching recesses 21 in the illustration,
One or three or more may be provided consecutively in the front-rear direction.

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.

Further, in the above embodiment, the coin storage bag 2 is sealed with the sealing tool 1 of the present invention, but the sealing tool 1 of the present invention is not limited to this, and can be used to seal various other items. It can also be used for

As described above, in the sealing tool according to the present invention, a sealing state indicating projection 43 is provided on the string presser piece 4 housed in the case 3 and is urged outward by an elastic support member 42. A sealing status display window 44 into which the protrusion 43 is fitted is provided on the upper wall 19 of the case 3 in correspondence with this protrusion 43, so that the sealing status display protrusion 43 is inserted into the supporting member 42 at the same time as sealing is completed. Case 3 due to elasticity
This allows the sealed state to be determined from the outside. For this reason, even a general user can easily determine the sealing state, and therefore, there is an effect that perfect sealing can always be achieved.
