Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sealing tool used, for example, to seal a coin bag.

A conventional sealing odor of this type consists of a fan-flat rectangular block made of lead and having four through holes for string insertion extending in the length direction and arranged in parallel.

The seal is made by first folding the opening of the bag into a zigzag shape on the double layer formed on the outside of one end of the seal by inserting the length into the four through holes of the sealing tool in a predetermined order. Fold it and put it in, then tighten the ring by squeezing both ends of the thin strip tightly.
Finally, the sealing punch was used to transform the sealing odor into a wave shape. The necessity of sealing such a coin bag is
For example, in the following case. In other words, bus companies that use one-man cars collect a large amount of coins every day. Calculating the total amount of such coins is very troublesome, so a bank employee takes a coin bag to the bus company, fills it with the collected coins without calculating it, seals it, and takes it to the bank. Once you get it home, calculate it and put it into your savings account. The sealing punch is from a bank, so not only is it a hassle to have to bring it with you every time you seal, but the opening of the bag is forced to fold into a zigzag shape against the restoring power of the cloth. , it is necessary to punch the sealing tool while holding both ends of the string tightly pulled by hand, and this operation requires a certain level of skill. An object of the present invention is to provide a very convenient sealing device that can be sealed by simply pulling a string inserted through the sealing odor without using a sealing punch. The sealing odor according to this invention consists of a block-shaped sealing body, a string inserted through the sealing odor body, and a narrow leaf spring for preventing pulling out built into the sealing body. A pair of string insertion through-holes are formed, each of which has a bent portion that bends inward from each other in a dogleg shape, and between the string insertion through-holes of the seal main body. The position includes a communication hole that connects the through-hole for inserting the rain thread, and a board-stamping storage that extends on both sides between the place where the communication hole is suitable for insertion and the bent part of the through-hole for both string insertions. The thin pull-out prevention leaf spring has two movable parts whose tips protrude into the through-holes for inserting the string, and the leaf spring storage space is formed to accommodate the movement of the string pull-out prevention spring. It has a space in which the portion is bent inward and accommodated.

Since the sealing odor according to the present invention has the above-described configuration, sealing can be performed by a simple operation such as pulling a string inserted through the sealing odor.

In addition, since both of the string insertion through-holes each have a bent portion, insert something like a screwdriver into the narrow insertion through-hole to bend the movable portion of the thin pull-out prevention leaf spring inward. Misbehavior such as pulling the string can be prohibited. In this specification, left refers to the left side of Figure 1, right refers to the right side of Figure 1, front refers to the lower side of Figure 1, rear refers to the upper side of Figure 2, and upper refers to the upper side of Figure 2. , and below refers to the lower side of the same figure.

Embodiments of the present invention will be described below with reference to the drawings.

1 to 7 show a first embodiment of the invention.

This sealing tool includes a sealing tool main body 1 having a fan-square shape, a round strip 2 inserted into the sealing odor main body 1, and a thin strip spring 3 for preventing the odor from being pulled out built in the sealing odor main body 1. Seal body 1
is made of polyacetal resin. In the sealing odor main body 1,
A pair of left and right through-holes 4 and 5 for general military use are shown, which are substantially parallel to each other.

The cross sections of the thin insertion through holes 4 and 5 are vertically elongated rectangles, and are formed in a size that allows two strings 2 to be passed through them, one above the other. Further, the rear ends of the through-holes 4 and 5 for inserting the strings are bent inward from each other in the shape of a 〈〉, and these portions serve as bent portions 41 and 51. At a position between the through holes 4 and 5 for inserting both strings in the sealing body 1, there is a communication hole 6 that connects the center of the length of the through holes 4 and 5 and the front end thereof with each other, and a connecting hole 6 for connecting both strings. Both sides of the through holes 4 and 5 for insertion communicate with each other at a position between the place where the communication hole 6 passes and the bent portions 41 and 51 (at the center of the length of the through holes 4 and 5 for both string insertion). A space 7 for storing a leaf spring is formed. The cross-sectional shape of the communication hole 6 is formed into a rectangular shape similar to the through holes 4 and 5 for thin insertion. The leaf spring storage space 7 is approximately in the shape of an inverted V when viewed from above, and consists of a central curved portion 71 and both side oblique portions 72. It has a wide width and is suitable for narrow insertion through holes 4 and 5. Both inclined surfaces of this both-side inclined portion 72 are indicated by 73 and 74. Recesses 8 are formed in the front and rear end surfaces of the sealing odor main body 1, respectively. Such a sealing odor main body 1 has various hole forming bodies 9 in order to incorporate a thin pull-out prevention plate spring 3.
and a hole cover body 10. The various hole forming bodies 9 include through-holes 4 and 5 for thin insertion with open upper surfaces, communication holes 6,
It has a cavity 7 for storing a leaf spring and a recess 8. Moreover, the various hole forming bodies 9 are formed with hard parts 11 on both sides.
The hole cover 10 has a flat plate shape and has downwardly projecting greens 12 formed on both sides. This hole cover 10 closes the string insertion application through holes 4 and 5, the communication hole 6, and the leaf spring storage space 7 of the various hole forming bodies 9, and forms the upper wall of the recess 8. The thin pull-out prevention leaf spring 3 has a substantially inverted V shape when viewed from above, and includes a fixed part 31 housed in the central curved part 71 of the leaf spring storage space 7 and two movable parts 32 housed in the inclined parts 72 on both sides. It consists of.

The tip end of each movable part 32 projects into the string insertion through holes 4 and 5, respectively. The leaf spring 3 is made, for example, by bending a band-shaped metal plate. The seal is assembled as follows.

First, from the rear of the various hole forming bodies 9, the thin strips 2 are inserted into the bent portions 41 of one of the thin through-holes 4, the communication hole 6, and the bent portions 51 of the other string insertion through-holes 5. Then, the end of the string 2 extending rearward from one through-hole 4 for narrow insertion is inserted from the rear into the through-hole 5 for narrow insertion so that a double ring 13 is formed at the rear of the various hole forming bodies 9. At the same time, the end of the slender 2 extending forward from the other slender insertion through-hole 5 is inserted into one slender insertion through-hole 4 from behind. Next, the leaf spring 3 is ironed into the leaf spring storage space 7 while bending the movable portion 32 inward. Then, the hole cover body 10 is placed over the various hole forming bodies 9 so that its downward protruding edge 12 rests on the step portion 11 of the various hole forming bodies 9, and is welded to the various hole forming bodies 9. This state is shown in FIGS. 1-3. To seal the coin bag, after putting the row 4 of the coin bag into the double ring 13 formed at the rear of the sealing device, pull both ends of the thin strip 2 extending forward from the front end of the sealing body 1. The diameter 13 becomes smaller and the mouth 14 of the bag is closed.

The movable part 32 of the leaf spring 3 is bent inward to allow the movement of the thin 2 in the direction of pulling the thin 2 (front direction), but the direction of pulling the thin 2 out of the odor sealing body 1 (backward) In contrast, the tip of the movable part 32 bites into the string 2 due to the elastic force of the leaf spring 3. When the opening 14 of the bag is closed according to theory 13, the restoring force tries to open it and loosen the ring 13, but Hosho 2 cannot move in the direction of loosening the ring 13, so the opening 14 of the bag is closed. It is kept in this state and the sealing is completed here. This state is shown in FIG. After sealing, even if you try to pull out the thin 2 from the sealed odor main body 1 by pulling the logic 13, the tip of the movable part 32 of the leaf spring 3 will dig deeper into the thin 2, so you will not be able to pull out the thin 2.

Even if you try to pull out the thin strip 2 forcibly, the movable part 32 will fall on the inclined surface 7.
4, the tip of the movable part 32 is still narrowed to 2 and is kept in a compressed state. And finally, the moving part 3
The string 2 is cut from the point where the tip of the string 2 is bent. Therefore, it cannot be restored. If the string 2 is cut in this way, it means that the bag has been tampered with. Furthermore, even if you insert something like a screwdriver into the through holes 4 and 5 for thin insertion and try to bend the movable part 32 of the leaf spring 3 inward to pull out the thin 2, the tip of the driver will not fit through the through holes 4 and 5 for thin insertion. The leaf spring 3 is stopped by the bent portions 41 and 51 of 4 and 5.
The movable part 32 cannot be bent inward.

8 and 9 show a second embodiment of the invention.

In this embodiment, the shape of the leaf spring storage space 7A of the sealing odor main body 1 and the thin pull-out prevention leaf spring 3A are different from those of the first embodiment.

The width of the central straight portion 71A gradually increases toward the rear end, and the rear end portion is formed into a substantially semicircular shape when viewed from above. The both-side inclined portions 72A are substantially the same as the both-side inclined portions 72 of the first embodiment. The leaf spring 3A has a substantially inverted Y shape when viewed from above, and has a substantially inverted U-shaped fixed part 31A that is stored and fixed in the central straight part 71A of the leaf spring storage space 7, and two movable parts that are stored in both side inclined parts 72A. It consists of a section 32A.

This leaf spring 3A is made by bending a band-shaped metal plate. In this sealing tool, the leaf spring 3A is formed into a substantially inverted Y shape when viewed from above, and its fixing part 31A is firmly fixed to the central straight part 71A of the leaf spring storage space 7A.
The leaf spring 3A does not shift within the space 7A. FIG. 10 shows a modification of the thin pull-out prevention leaf spring.

The shape of this leaf spring 38 is almost the same as that of the leaf spring 3A of the second embodiment (Y-shape), and consists of a fixed part 31B in the center and movable parts 32B on both sides. It is made by aligning L-shaped metal plates symmetrically and welding them together.In this case, the space for storing the leaf spring in the odor sealing body 1 is shaped like an inverted Y when viewed from the top, almost the same as in the second embodiment. It is formed in the shape of a letter.The material of the odor sealing body is polypropylene made of polyacetal resin, nylon,
A suitable synthetic resin such as Amo resin is used.
