A tooth (1) of a slide fastener comprises of:
- a clamp portion (7) is provided on a side, having a slit (2) for receiving a fabric tape, one end of said clamp portion (7) forms a left wall (12) of said tooth (1);
- a hook portion (3) is extended from another end of the clamp portion (7) forming a dimple (8) and a right wall (11) of said tooth (1);
- a slot (4) parallel to said slit (2) is provided on an outer wall of said hook portion (3);
- a blocking member (5) parallel to said slot (4) is provided at said dimple (8);
- and
- a joint member (6) is projected from said right wall (11) where is close to the slot (4).
A slide fastener consists essentially of a left and right fabric tapes (30, 30A), each has a row of indentations corresponding each other to form a chain (40) and a slider (50) for meshing and separating said indentations of two fabric tapes (30, 30A);
- characterized in that:
- each indentation of said left and right fabric tape (30, 30A) is the tooth (1);
- the tooth (1) is affixed to the left and right fabric tape (30) by the clamp portion (7);
- the hook portion (3) of each tooth (1) of left fabric tape (30) engages the dimple (8) of each tooth (1) of said right fabric, tape (31);
- the slot (4) of each tooth (1) of said left fabric tape (30) accommodates the blocking member (5) of each tooth (1) of said right fabric tape (31A);
- and
- the joint member (6) of each tooth (1) of left fabric tape (30) butts the joint member (6) of each tooth (1) of said right tape (30A).
