The zipper head 30 of the present invention is provided with a partitioning piece 31, by which the partitioning piece 31 can partition the upper and lower sides of the zipper head 30 from an upper guiding groove 32 and a lower guiding groove 33, respectively. A top plate 34 is disposed above the upper guide groove 32, and a pull tab 35 for pulling the zipper head 10 forward and backward is disposed above the top plate 34.

 The seal type zipper head 30 of the present invention is characterized in that the partition piece 31 is extended and extended toward the front end and the rear end, respectively. When the separator 31 is expanded toward the front end, a sealed end 311 having a beveled triangular block shape is formed. The shape of the upper or lower surface of the partitioning piece 31 extending toward the sealing end 311 may be a flat surface or a slightly arcuate convex shape, and is not particularly limited thereto, but can be applied to the chaining of the fastener tape in the future. The chain belt is more conformable, and it is preferably a slightly arcuate convex shape. While the separator 31 is extended toward the front end, the right side plate 313 is also extended and lengthened at the same time. In addition, in order to match the shape of the slit, when the separator 31 is expanded toward the front end, the sealed end 311 formed by the cross section may also be an equilateral triangle (see FIG. 9), and the surface on the second side may also be slightly arcuate. It is convex, but its configuration is not particularly limited herein.

 On the other hand, the separator 31 is extended to the rear end to form a closed end 312. When the separator 31 is extended rearward, the distance between the original separator 31 and the top plate 34 is gradually narrowed, that is, the height of the upper guide groove 32 is gradually lowered toward the rear end of the slider 30, and the upper guide groove is formed. The height of the 32 (the height between the closed end 312 and the top plate 34) is such that the first chain groove 211 slides through, forming a tight state between the first chain groove 211 and the upper guide groove 32, avoiding the upper guide groove 32. In communication with the lower guide groove 33, a leak path through the upper guide groove 32 to the surface of the slider 30 is formed by the lower guide groove 33. In addition, in order to further strengthen the gap between the lower guide groove 33 and the second chain groove 221, when the partition piece 31 is extended rearward, the height between the bottom plate 36 and the closed end 312 can be the second chain groove 221 at the same time. When the slip is passed, the tight state can be simultaneously formed between the second chain groove 221 and the lower guide groove 33, and the sealing effect is further enhanced.
