Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sealing tool used for sealing, for example, hard bags.

Conventional seals of this type have consisted of a flat rectangular block made of lead and having four through-holes extending in the lengthwise direction and arranged in parallel for the passage of cords. Then, the seal is first attached to a double ring formed on the outside of one end of the sealing device using strings that are inserted in advance into the four through holes of the sealing device in a predetermined order.
This was accomplished by folding the opening of the bag in a zigzag pattern, then tightening both ends of the string to shorten the loop, and finally using a sealing punch to transform the seal into a wavy 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 extremely troublesome, so bank employees bring coin bags to the bus company, fill them with the collected coins without calculating them, seal them, and send them to the bank. They take it home, calculate it, and then put it into savings. Since the sealing punch is from a bank, not only is it a hassle to have to bring it with you every time you seal the bag, but the opening of the bag is forced to fold into a zigzag shape against the restoring force 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 skill.

An object of the present invention is to provide a very convenient sealing tool that can be sealed by simply pulling a string inserted through the sealing tool without the need for a sealing punch.
