The disclosure discloses a method for forming a rubber layer on a surface of a resin material. In the method, painting is first performed on the surface of the resin material to form a painting layer, using a paint to which a pigment has been added; then, rubber coating is performed to form a rubber layer on the painting layer. The method of the disclosure may be used in surface treatment of a fastener product. The disclosure further discloses a slide fastener, a buckle and a snap button using the method of the disclosure. The method of the disclosure may solve a conventional problem that a rubber coating is likely to fall off a resin surface, and the rubber on the surface of the resultant fastener product is less likely to fall off.

The present invention relates to a sensing device (10) designed for being applied on a first flap (11) and on a second flap (12) of an opening (13) arranged in a wearable item (14). The sensing device (10) comprises: a triggering element (20) arranged on the first flap (11) of the opening (13) and comprising an activating component (23); a switch element (30) arranged on the second flap (12) of the opening (13) and comprising a sensing component (33); the sensing component (33) being designed for emitting an electrical output signal when it is put in a predetermined mutual position with respect to the activating component (23). According to the invention the triggering element (20) is provided with at least one alignment component (22; 22A, 22B) designed for interacting with a corresponding alignment component (32; 32A, 32B) of the switch element (30) so as to autonomously and automatically put in said predetermined mutual position the activating component (23) and the sensing component (33) when the first flap (11) is drawn close to the second flap (12), or viceversa. The invention also relates to a closure device comprising said sensing device (10) and to a method for manufacturing said sensing device (10).

A child resistant zipper closure for a plastic bag includes a double slider, including a first slider and second slider. The first and second sliders are oriented on the zipper closure such that when at least one of the first slider and second slider is moving in a direction toward the other of the first slider and second slider, the zipper is interlocking; and when at least one of the first slider and second slider is moving in a direction away from the other of the first slider and second slider, the zipper is unlocking. The first and second sliders can be realeasably connected together.
