A button comprises a button body (10, 10a, 10b) and a prong (20, 20a, 20b) adapted to be arranged on the side of cloth (30) opposite to the side thereof on which the button body mentioned above is set in place to nip the cloth therebetween and to fixedly secure the button body to the cloth. The button body mentioned above contains an outer shell member (13), which comprises a button back (15, 15a, 15b) and a cap (14, 14a, 14b), and an insert (11, 11a, 11b) accommodated in the outer shell member. In order to make a whitish button which could be heretofore obtained only by plating, at least the button back mentioned above is made of aluminum or an aluminum alloy. Preferably, the button back mentioned above is made of an aluminum alloy containing 3-6% by weight of magnesium, and the cross-sectional thickness of the above-mentioned button back is in the range of 0.25-0.6 mm. Further, it is desirable that the above-mentioned cap and the insert should also be made of an aluminum alloy.

The invention concerns a cap rivet having a cupped part (10) with a free-lying top side (12) and a bottom side (14) and a rivet part (20) with a shaft (22) extending from the bottom side (14) of the rivet part (10), a flange (24) stretching to and away from the shaft axis (23), which serves to fix the rivet part (20) to the cap part (10) and two supporting parts (28, 30) placed between the shaft (22) and the cap part (10), extending slightly parallel to the bottom side (14) of the rivet part (10). Two flange windows (26, 27) are formed by bending two flange parts about the folding lines running between the windows (26, 27) and the shaft (22). The invention proposes that one of the supporting parts (28) is bent over the other supporting part (30) in such a way that one of the sides of one supporting part (28) opposing the bottom part (14) of the rivet part (10) lays at least partially on the side of the other supporting part (30) facing the lower part (14) of the rivet part (10).

A method and apparatus for molding a plastic cap (120) on a preformed metallic shanked member (62) includes inserting the shanked member (62) in a strip material (24) by a shank insertion device (60) such that the head (66) of the shanked member (62) is elevated above the strip material (24). A molding device (110), having an open mold cavity (116) is engaged with the strip material (24) such that the strip material (24) acts as a portion of the mold. The elevated head (66) is positioned within the mold cavity (116). Plastic is injected into the mold cavity (116) to surround and encapsulate the head (66).

Disclosed is a snap fastener, comprising a face fastener (1) and a locating fastener (2) which are snapped with each other, wherein the face fastener (1) comprises a face shell (11) provided with an installation chamber (111), and a locating pin (12) made of plastic and integrally formed; and the locating pin (12) comprises a base (121), a rod body (122) and anti-rotation protrusions (125), wherein the base is accommodated in the installation chamber (111), and anti-skidding structures (124) are arranged on the end face, exposed out of the installation chamber (111), of the base (121); the rod body stands exactly on an end face of the base (121), and the end, away from the base (121), of the rod body (122) is used to be connected to the locating fastener (2); the anti-rotation protrusions are arranged at the outer edge of the end face, in connection with the rod body (122), of the base (121) in a protruding manner, and the ends, away from the base (121), of the anti-rotation protrusions (125) retract; and when the locating pin (12) and the face shell (11) are assembled, the face shell (11) completely covers the anti-rotation protrusions (125) and is meshed therewith. In the implementation of the snap fastener of the present invention, the face fastener (1) can be separated into the face shell (11) and the locating pin (12), and the locating pin (12) is manufactured into a standard part for batch production and storage, thereby adapting face shells (11) with continuously updated designs, shortening delivery time, and reducing costs.
摘要:
A pressure button, of the type comprising a male portion and a female portion, to be applied on flaps to be connected, the female portion comprising a fixing element for fixing an active female element, the latter including a plurality of resilient tabs which are mutually arranged with a ring arrangement about a housing recess for housing a projecting part of the male portion. The active female element of the button comprises an annular body to which a clamp element including a plurality of points projecting outside of the active female element is affixed. In particular, the assembling means for assembling the female portion are so arranged as to operate at a separated and moved away position from the resilient tabs, thereby the assembling of the female portion, for applying the latter on a respective material flap, can be performed without modifying the mutual shape and/or arrangement of the resilient tabs, thereby preserving the rated clamping pressure of the button.
摘要:
A button body (11) has a housing (11A) for a tip end (12A) of the fixture (12) to be inserted therein. The fixture (12) has a shoulder (12C) between the tip end (12A) and a tubular portion (12B) formed continuously from the tip end (12A). The shoulder (12C) has an edge (12F) as a cutting portion to cut a fabric (1) with an insertion end (11E) of the housing (11A) of the button body (11). Without applying a big force to the edge (12F), the fabric can be cut easily regardless of the thickness of the fabric.
