Embodiments include a dead person's locking pull tab (42L, 43L), a locking tab holder (44), a locking pull tab (40T), additional molding (40M, 40E 42M), locking flanges (42R, 42F, 42), and a releasable, interlocking rigid buckle for instantly coupling the closure system.

Abstract: An inclined slope face portion is formed on a top face of a box member. This slope face portion has a downward gradient from a side wall of a box-pin-insertion hole up to a side wall of an insert-pin-insertion hole. The insert pin is inserted into the box member in which the box pin is inserted and fixed in a box-pin-insertion hole thereof. Then, when a rear end portion of a slider is brought into contact with the box member, the slider is inclined relative to the box member. Although conventionally, the insert pin was inserted into the insert-pin-insertion hole of the box member from just above the box member, this invention allows the insert pin to be inserted obliquely from above the box member. Therefore, the insertion operation can be carried out smoothly and easily. Thus, the slider is disposed in an inclined posture relative to a box member of the separable bottom stop assembly so as to achieve a smooth operation for inserting the insert pin.

Abstract: By fusing reinforcing tapes with bottom end attaching portions of fastener tapes by pressurizing heating means with different pressures (i.e., high and low), thus weakening of attaching portions can be prevented. Core threads are fitted to side edges of fastener tapes to form core portions. Reinforcing tapes formed of thermoplastic elastomer film or thermoplastic resin film are fused to wrap tape end portions including the core portions so as to form the bottom end attaching portions. The reinforcing tapes fused the core portions and vicinity portions to the fastener tapes with a low pressure and at tape main body portions to the fastener tapes with a high pressure, thereby making the core portions and the vicinity portions flexible and thick and making the tape main body portions stiff and thin to form stepped portions. The stepped portions are positioned outside flanges of a slider.
