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 has a problem in that if only one of the two loops is pulled strongly from the object to be sealed in the sealed state, there is a slight possibility that the string may loosen. Ta.

This invention solves the above-mentioned problems and provides a sealing device that can achieve a perfect seal without causing the string to loosen at all even when only one of the string portions is pulled strongly from the side of the object to be sealed in the sealed state. It is intended to.

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.

The height of 2 is almost the same as the height of the string presser protrusions 13, 13, and string release gaps 53, 53 are formed between the stoppers 52, 52 and the inner surface of the upper wall 19 of the case 3. There is. On the inner side of each upper edge of the wedges 50, 50, string release notches 54, 54 are provided with gaps 53, 5.
It is located at almost the same level as 3. In some cases, the stoppers 52, 52 may be omitted. The inner surfaces of the wedges 50, 50, that is, the string abutment surfaces are made into uneven surfaces to increase the frictional resistance with the string 5. Of course, these string contact surfaces may be flat.

The string presser piece 4 has a substantially truncated triangular shape when viewed from above, and three string presser protrusions 13 are provided on the left and right side walls 11 and 12 thereof. Further, a thin wall portion 17 is formed on the lower side of the rear end of the string holding piece 4, and a detent protrusion 18 is provided at the tip of this thin wall portion 17. Correspondingly, two latching recesses 21 into which the detent projections 18 are fitted are provided at predetermined locations on the lower wall 20 of the hollow portion 6 of the case 3, and one latching recess 21 on the rear side thereof.
A recess 22 for waiting the detent protrusion is provided. Here, the bottom wall of the standby recess 22 is flat, but the bottom wall of the latching recess 21 is inclined upward toward the front. Latch recess 21
are arranged continuously, and the detent protrusion 18
is sealed by fitting into the first latching recess 21, but the string 5 is further tightened with a stronger force than this.
The cord presser piece 4 is configured to move forward even when the cord is tightened.

A sealed state display projection 43 is provided on the upper wall of the string holding piece 4 and is urged outward by an inverted U-shaped support member 42 when viewed from the elastic side. A sealed state display window 44 into which the protrusion 43 is fitted is opened at a predetermined location on the upper wall 19 of the case 3 on the same side as the protrusion 43, and the protrusion 43 and the upper side 42a of the support member 42 are formed on the inner surface of the upper side wall 19. Concave grooves 45 for guiding the window 44 are provided on both front and rear sides of the window 44 so as to extend the grooves. In the state shown in FIGS. 1 and 5 with two-dot chain lines before sealing, the projection 43 and the front end of the upper side 42a of the support member 42 are fitted into the guide groove 45. Further, an inclined surface 46 is provided at the rear end of the base of the supporting member 42, and the inclined surface 46 is inclined downward toward the rear. This allows the air to escape effectively to the inside of 3.

On both sides of the bent portion of the support member 42 at the front end of the string presser piece 4, triangular-shaped protrusions 47, 47 for preventing lifting of the string presser piece are provided. The upper ends of these protrusions 47, 47 are opposed to the upper wall 19 on both sides of the guide groove 45 with a slight gap, and as described later, when the string holding piece 4 moves forward,
When the front end of the upper side 42a of the support member 42 integrated with this supports passes directly under the sealing state display window 44, the front end of the upper side 42a is prevented from fitting into the display window 44. It is something.

Furthermore, thin string separation protrusions 48, 48 and 49, 49 are provided on both left and right sides of the string presser protrusions 13, 13 at the front and rear ends of the string presser piece 4, respectively. These projecting parts 48, 48, 49,
49 serves to separate the upper and lower parts of the string 5 on both the left and right sides of the string presser piece 4, and also to separate the string 5 parts arranged above and below from each other on both sides of the string presser piece 4. , serves to prevent the string holding piece 4 from rotating within the case 3.

As shown in FIG. 1, a knot 23 is provided at the center of the required length of one string 5 to prevent the string 5 from slipping, and the string 5 is tied approximately at the center around this knot 23. This folded part 5

In addition, on both the left and right sides of the string holding piece 4, the starting ends 15a,
25a and the intermediate portions 15b, 25b are arranged to overlap vertically. Here, string part 1
Since the starting ends 15a, 25a of the wedges 5, 25 do not need to be held down during sealing, they are arranged on both the left and right sides of the narrow support member 42 above the string holding piece 4, and Relief notch 5
4, 54 and the string release gap 5 between the stoppers 52, 52
3 and 53 so as to be opposed to these. On the other hand, both string parts 15, 2
The intermediate portions 15b, 25b of 5 are positioned between the string presser protrusions 13, 13 on both left and right sides of the presser piece 4 and the wedges 50, 50 in order to be held down during sealing, respectively. It is located at the bottom.

At the front end of the case 3, a string locking protrusion 37 having an arcuate cross section is provided. 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 37 does not have to have an arcuate cross-sectional shape, 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-sectional shape. It may be something that you have.

The case 3 is made of synthetic resin such as ABS, and as shown in FIGS. 8 to 11, 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 the left and right edges of the upper half 3a, and a rear wall 31 on the rear end thereof.
is provided. Rear wall 31 and left and right hanging parts 2
A gap 32 of a required width between the rear ends of 9 and 30,
32 are opened in each. The lower half body 3b has a rectangular shape of the same size as the upper half body 3a, and has a pair of rising portions 33, 34 on the left and right side edges of the lower half body 3b.
In addition, a triangular front wall 35 is provided at the center of the front end, and 52 strings can be inserted between the front wall 35 and the front ends of the left and right rising portions 33 and 34, respectively. width gap 36,
36 is opened in an inverted C shape when viewed from the plane. In addition, the upper wall of the lower half body 3b is the case 3 after combination.
It constitutes the lower wall 20 of the hollow part 6,
At the rear of the upper wall of the lower half 3b, there is a detent protrusion standby recess 22 into which the detent protrusion 18 of the string holding piece 4 is fitted, and a detent protrusion latching recess on the front side thereof. 21 is 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 11 and 12 of the hollow portion 6 of the case 3, and a wedge-fitting recess 51, 51 are provided respectively. The string loosening prevention protrusion 37 is provided on the lower half body 3b.

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 installing the string holding piece 4, a pair of wedges 50, 50, and one string 5 between the upper half body 3a and the lower half body 3b as shown in FIG. The upper half 3a and the lower half are bonded by welding the lower walls of the left and right hanging parts 29, 30 of the upper half 3a and the left and right edges of the upper wall of the lower half 3b to each other using a welding device. The body 3b is integrally joined to form a case 3, and a sealing tool 1 is attached in which a string pressing piece 4, a pair of wedges 50, 50, and a string 5 are incorporated in a predetermined arrangement. It will be done. In order to facilitate the work of assembling the pair of wedges 50, 50, for example, when molding the wedges 50, 50, a thin band-shaped connecting piece is integrally formed to connect the wedges 50, 50 to each other. In some cases, they may be inseparable. In this case, the belt-like connecting piece is the string holding piece 4.
It may be arranged below or above so as not to obstruct the back and forth movement of the string presser piece 4.

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 device 1 is sealed, Fig. 1 and Fig. 2
As shown by the two-dot chain in the drawings and FIG.
The sealed state display projection 43 is fitted into the standby recess 22 and is pressed into the case 3 against the elastic force of the support member 42. Wedge 50,5
0 are recesses 51 and 5 in the left and right side walls 7 and 8 of the case 3
1 in a relatively free state.
The first ring part 16 and the second ring part 26 of the string 5 form a double ring with the 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. 3 to 5, the string presser piece 4 is moved forward together with the string folded portion 5a. The wedges 50, 50 on both sides of the string holding piece 4 are fitted into the recesses 51, 51 of the case 3 in a relatively free state, and the wedges 50, 50 are in contact with the rear wall of the recesses 51, 51 from the beginning. In this case, it does not move as it is, but the wedges 50, 50 are in the recesses 51, 51.
When the string holding piece 4 moves forward as described above, the wedges 50, 50 on both sides of the string holding piece 4 are pushed against the inclined side walls 7, 8 of the case 3 due to the reaction force. The wedges 50, 50 eventually come into contact with the rear walls of the recesses 51, 51 in any case. Therefore, the wedges 50,50 and the stoppers 52,5
There will be a gap between the two.

As the string presser piece 4 moves forward, the desired intermediate portions 15b, 25b of the string 5 are moved against the left and right side walls 11,
12 and the wedges 50, 50 and is held down by the string pressing protrusions 13, 13, and the detent projection 18 of the string pressing piece 4 is held together with the thin part 17 by the elasticity of the thin part 17. After the detent protrusion 18 is fitted into the latching recess 21 and latched to the rear wall of the recess 21, the string holding piece 4 is prevented from retreating, and the coin is The sealing of 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 in this state, the knot 23 of the string 5 fits under the protrusion 43, so the protrusion 43 is further pushed up by the knot 23, so that the protrusion 43 fitted into the display window 44 Even if you push it down a little from the outside, it will not go into case 3.

Further, in the sealed state by tightening the string 5, only one of the string portions 15, 25 of the two ring-shaped portions 16, 26, for example, the string portion 15, is attached to the object to be sealed.
When it is pulled strongly from the side, as shown in FIG. The intermediate portion 15b of the string 5 is further firmly held down by the secondary force, and therefore the string portion 15 is not pulled out toward the object to be sealed 2 at all. . Therefore, the string 5 never loosens and can achieve a perfect seal.

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, but these ring-shaped parts 16, 2
6 can also be wrapped twice or more to seal.

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. Although the protrusion 43 is provided on the upper wall of the string presser piece 4, it may also be provided on the lower side wall of the string presser piece 4, in which case the detent protrusion 18
may be provided on the upper wall 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.
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. 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, the folded part 5a of the string 5 is attached to the string pressing piece 4.
Although it is preferable to fix the string 5 with adhesive or the like, it is difficult for the string 5 to shift from side to side during the sealing work. The folded portion 5a may be fitted into the fitting groove.

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 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. It is.

Further, in the above embodiment, three cord presser protrusions 13, 13 are provided on each of the left and right side walls 11, 12 of the cord presser piece 4;
It is sufficient that at least one is provided.
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.

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 hollow part 6 of the case 3, the left and right pair of wedges 50, 50, and one string 5. In the sealed state in which the intermediate parts 15b and 25b are held down by the string holding piece 5 by tightening the string 5, the string portions forming the two ring-shaped parts 16 and 26 are viewed from the side of the object to be sealed 2. Even if only one of the strings 15 and 25 is pulled more strongly, the so-called secondary holding action of the wedge 50 prevents the string 5 from loosening at all, thus achieving a complete seal. It has the effect of gaining.
