Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sealing tool used for sealing, for example, mail storage bags and coin storage bags.

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. (Patent Application No. 186351 (1983)
-75278)). The sealing device proposed in the future is
For example, by inserting the opening of a mail storage bag into the looped part of the string formed through the case and pulling one end of the string outside the case, the opening of the bag can be held by the looped part of the string. It is very convenient because it is tightened and the middle part of the string is held down by the string pressing piece inside the case, making it very easy to seal the mail storage bag. However, the string used in the sealing device is made by twisting together many threads and has elasticity, so in the case of the above-mentioned sealing device, after sealing the opening of the bag, There was a slight fear that the string presser piece would be pushed back slightly by the repulsive force based on the elasticity of the string, and as a result, the force of the string presser piece to hold the string would loosen, resulting in incomplete sealing.

This invention was made in view of the above points,
To provide a sealing tool capable of completely sealing a mail storage bag, etc., without causing the string presser piece to be pushed back at all after sealing the bag.

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

As shown in FIG. 3, case 3 is, for example,
It is made of synthetic resin such as ABS and is made by integrating an upper half 3a and a lower half 3b formed by molding by fusion bonding. The upper half 3a and the lower half 3b are the case 3 divided horizontally at the center of the height. The hollow part 6, the string presser protrusion 13, the string insertion holes 17, 18, 19, the latching recess 24, etc. are each half the size and are formed opposite to each other, and the case in Fig. 3 is different from the case in Fig. 1. For the parts corresponding to the parts in Case 3, "a" is added for the upper half 3a, and "b" is added for the lower half 3b in addition to the reference numerals in the state of case 3. Note that the joint surface 26 between the upper half body 3a and the lower half body 3b
A and 26b are provided with a pair of left and right dowels 27 and 2 to facilitate positioning when combining the two.

A and the lower half 3b are integrally joined to form a case 3, and a sealing tool 1 is produced in which a string presser piece 4 and a string 5 are assembled at predetermined positions in the case 3.

Next, how to use the sealing tool 1 will be explained.

First, 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 2 of the string presser piece 4 is
3 is a standby recess 25 at the rear end of the left side wall 7 of the hollow part 6
It's stuck inside. and the ring-shaped part 16 of the string 5
The opening of the mail storage bag 2 is inserted into the case 3, and in this state, the end 5c of the string 5 on the outside of the rear part of the case 3 is pulled. Then, the size of the annular portion 16 decreases and the object to be sealed 2 is tightened by the annular portion 16, and when the annular portion 16 is tightened the most,
As shown in FIGS. 4 and 5, the string pressing piece 4 is attached to the string 5.
The desired intermediate portion 5b of the string 5 is moved forward together with the one end portion 5a, and the desired intermediate portion 5b of the string 5 is sandwiched between the right side wall 12 of the string presser piece 4 and the right side wall 8 of the hollow portion 6, and the string presser protrusion 1
3 and 14, and the detent protrusion 23 is fitted into the latching recess 24 near the front end and latched to the rear wall of the recess 24, thereby preventing the string holding piece 4 from retreating. This is prevented, and the sealing of the mail storage bag 2 is completed. When the string presser piece 4 moves forward, its detent protrusion 23 moves from the standby recess 25 to the latching recess 24, and then from the rear latching recess 24 to the front latching recess 24. At this time, since the string 5 itself has some elasticity, the string holding piece 4 is moved forward while moving slightly toward the string 5 side, that is, to the left, against the elasticity of the string 5. It is. When the required intermediate portion 5b of the string 5 is pressed down to a state where it can no longer be deformed by the string pressing protrusions 13 and 14, the string holding piece 4 becomes unable to move forward, and at that position, the detent protrusion 23 is latched to the rear wall of the latching recess 24 into which it is fitted, and the string holding piece 4 is also unable to move back, thereby completing the sealing of the mail storage bag 2. It is something to do.

In addition, although the ring-shaped part 16 of the string 5 of the sealing device 1 is wrapped around the opening of the mail storage bag 2 only once in the illustrated example, the ring-shaped part 16 is wrapped around the opening of the mail storage bag 2 two or more times to seal it. You can also do that.

Although these are integrally joined to each other by fusion, the upper half 3a and the lower half 3b may of course be joined by so-called adhesion or welding. Moreover, the case 3 can also be made by other methods. Further, the case 3 is shown in the shape of a circular block, but it may of course be of other block shapes such as rectangular, polygonal, or spherical. 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, in the first embodiment, one end 5a of the string 5 is passed through the string insertion hole 19 of the string presser piece 4, and the knot 15 at the tip is hooked to the rear wall 20 of the string presser piece 4. In addition, for example, the upper wall of the string holding piece 4 is provided with an elongated string-fitting groove that opens forward and upward, and a wide knot-fitting groove connected to the rear of the groove, and the string 5 is inserted into these grooves and the groove. One end 5a of the string 5 may be attached to the string holding piece 4 by fitting the one end 5a and the knot 15, or one end of the string 5 may be attached when the string holding piece 4 is made by molding. The part 5a may be embedded, and one end part 5a of the string 5 is held by the string pressing piece 4.
The means for attaching it to is arbitrary.
