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. (Patent Application No. 175770 (1983)
-Refer to No. 64884). 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 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 concern 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.
