The cross section of the general engaging part 11 in the tooth thickness direction is generally omega-shaped, that is, the front end of the general engaging part 11 in the engaging direction is a convex head part in a circular arc shape, and the rear end is a neck part in a contraction shape, when the two engaging parts 11 are engaged in the front and rear direction, the convex head part of one engaging part 11 on one side cloth belt 2 is pressed into from the convex head parts of the two engaging parts 11 on the other side cloth belt 2, so as to be clamped between the neck parts of the two engaging parts 11, thereby forming an engaging state. Specifically, the cross section of the engaging portion 11 in the tooth thickness direction may be made to be convex so that a groove on one side can accommodate half of the front protrusion, and thus a cavity capable of accommodating the front protrusion is formed between two adjacent fastener elements at the groove formed by the neck portion after the protrusion is blocked.

Wherein fixed part 12 is used for fixed strap 2, mainly has tape slot 13, and tape slot 13 extends along 2 extending direction of strap to through tape slot 13 card on strap 2, with at 2 extending direction of strap, with the strap 2 between the transmission effort, transmit the effort of zip fastener switching direction promptly. The tank bottom of taking draw-in groove 13 generally is circular or square groove portion that expands to hold the rib portion of 2 one sides of strap, and the notch of taking draw-in groove 13 is the throat type, and the groove width generally suits with 2 area face thicknesses of strap, so that 2 area face portions of strap pass the throat type notch, with be connected with the rib portion in the tank bottom, prevent through the throat type notch that the rib portion of strap 2 shifts out taking draw-in groove 13 along the notch direction of taking draw-in groove 13. The engaging portion 11 and the fixing portion 12 are generally integrally formed, but may be fixedly connected by bonding, welding, or the like.

Wherein the engaging part 11 is less than 180 degrees and is greater than 90 degrees angles at tooth thickness direction central plane and the central plane contained angle of taking draw-in groove 13 in the groove width direction to the strap 2 of two meshing chain tooth strips when making the meshing is the contained angle and arranges, and the contained angle is greater than 0 degree and is less than 180 degrees angles. Wherein the thickness direction of the fastener elements of the engaging portion 11, i.e., the direction perpendicular to both the extending direction of the tapes 2 and the engaging direction. The central plane of the tape slot 13 in the slot width direction, that is, the thickness direction of the cloth tape, it should be noted that, when in use, the tooth thickness direction and the slot width direction of the tape slot 13 are both the inside and outside directions of the closed mouth closed by the fastener element strip. In the flat type fastener element, the angle between the center plane of the engaging portion 11 in the tooth thickness direction and the center plane of the tape slot 13 in the slot width direction is equal to 180 degrees.

In the zipper element, when in use, the zipper 1 elements are uniformly arranged on two cloth belts 2, and the corresponding zipper element 1 is selected according to the included angle between the opening edges at two sides of the closed opening and the included angle between the central plane of the meshing part 11 in the tooth thickness direction and the central plane of the belt clamping groove 13 in the groove width direction. If the angle between the mouth edges on both sides of the closed end is 90 degrees, then correspondingly, the fastener element 1 may be selected such that the angle between the central plane of the engaging portion 11 in the tooth thickness direction and the central plane of the tape slot 13 in the slot width direction is 135 degrees. In the fastener element 1, the included angle between the central plane of the engaging part 11 in the tooth thickness direction of the fastener element 1 and the central plane of the tape clamping groove 13 in the groove width direction is changed, so that the included angle between two engaged chain belts can be changed, the use of a closed opening with the included angles of the mouth edges at two sides not being flat angles is further met, and the use mode is simple and convenient. In conclusion, the zipper element 1 can effectively solve the problem that the zipper is inconvenient to use when the opening is not flat.
