The second lateral pressure portion is located outside the first fastener portion formed closer to the opening, and the second lateral pressure portion is outside the second fastener portion formed farther from the opening portion of the bag body than the first fastener portion. This is a slider of a bag formed so as to be located at a position.

[0006]

The second lateral pressure portion is formed continuously from the end of the first lateral pressure portion opposite to the horizontal portion, and the first lateral pressure portion is formed at a position closer to the opening of the bag body. The second lateral pressure part is located outside the one fastener part, and the second lateral pressure part is located outside the second fastener part formed farther from the opening of the bag body than the first fastener part. Has been the first
It is pressed and locked by the lateral pressure part to close the first fastener part, and is pressed and locked by the second lateral pressure part to close the second fastener part.

[0007]

According to the invention, a second lateral pressure portion is formed at the end of the first lateral pressure portion opposite to the laterally extending portion and continuously protrudes, and the first lateral pressure portion is located closer to the opening of the bag body. And the second lateral pressure portion is located outside the first fastener portion formed in the first fastener portion.
Since it is formed so as to be located outside the second fastener portion formed farther from the opening portion of the bag body than the fastener portion, the first fastener portion and the second fastener portion can be formed by one operation.
Any of the fasteners can be closed. Also,
Between the first lateral pressure portions, a projection is formed so as to protrude from the horizontal portion so as to be located between the fastener portions.
The first fastener portion can be disengaged and opened.

Therefore, the person using the bag does not forget to close both the first fastener and the second fastener, and can open and close both fasteners very easily. It can be kept even more.
