PURPOSE: To form a seal which is sealed until it is opened, and which is resealable thereafter by providing on a jaw a connection member which is moved to the holding position when a rib is inserted in a groove from the first depth to the second depth, and connects the rib to the groove at the third excessively closed insertion depth equal to the second depth, and cutting one side from the connection member in the first separation. CONSTITUTION: At the initial locking position between strips 13 and 14, a rib 17 is connected to a base part of a groove 12 by a peeling seal material 18, and a head part is completely inserted in a groove deeper than the regular one in spaces 19 and 20. Fingers 15 and 16 are operated like a regular fastener to be snap-fitted to an upper part of the head part. In the regular engagement position, a lower side of the head part is loaded on the surface of the fingers 15 and 16 to form a first insertion depth. When the rib is pressed into the groove, the rib is pressed to a second insertion depth where the fingers are snap-fitted to a base part of the head part. Further, a third insertion depth which is far larger is the complete insertion depth where the head part 17 is connected to the peel seal material 18. |
