Abstract: The present invention provides a molding sheet material having a sandwich structure produced by preparing a fiber reinforced thermoplastic resin layer (A) reinforced with a woven fabric or a knitted web and a fiber reinforced thermoplastic resin layer (B) reinforced with a random mat and using the layer (A) as a core layer and the layer (B) as a skin layer, or using the layer (B) as a core layer and the layer (A) as a skin layer. When this sheet material is molded into a three-dimensional structure, the layer (B) serves as a cushion to prevent the occurrence of a wrinkle or a crease in the layer (A). A toe puff for a safety shoe having a light weight and excellent pressing resistance can be prepared through the molding of this sheet material. In the sheet materials, the core layer or the skin layer consisting of a thermoplastic resin reinforced with a woven fabric or a knitted web of a reinforcing fiber may be prepared from a woven fabric or a knitted web of a reinforcing fiber alone.

Abstract: A button for being attached to a garment fabric has a button body composed of a double-walled tubular stem with an annular flange extending radially outwardly therefrom, a cap having an internal back place mounted on the annular flange, and a tack member having a central shank for penetrating the garment fabric and for extending into the tubular stem to join the tack member to the button body with the garment fabric interposed therebetween. The annular flange includes a first marginal wall flaring radially outwardly and having a plurality of radially outward projections. The cap also has a second marginal wall fitted over the first marginal wall and including a plurality of protuberances deformed radially outwardly by the projections, respectively. The projections and the protuberances are held in interlocking engagement for preventing the button body and the cap from rotating relatively to each other.

Abstract: A snap fastener for use on garment pieces comprises a male member attached by a first rivet to one of the garment pieces and a female member attached by a second rivet to the other garment piece. The male member includes a first cylindrical wall having an annular rim snapped in an annular groove defined in a second cylindrical wall of the female member. The male member and the first rivet have reinforcing ribs biting in the garment piece sandwiched therebetween, and similarly the female member and the second rivet have reinforcing ribs held in biting engagement with the garment sandwiched therebetween. The male and female members, and the first and second rivets are prevented by these reinforcing ribs from rotating with respect to the garment pieces, an advantage which manifests itself especially where the first and second rivets have directional ornamental patterns on their heads.

Abstract: A fastening for use on a garment comprises a base, and at least two flat spikes initially projecting from the base for being pierced through the garment into apertures of a hasp, and then for being deflected into a clenched condition against the hasp, there being at least two cold-pressed grooves each opening into an outer surface of the fastening and extending longitudinally thereof across a shoulder or joint between the base and a respective one of the spikes. The fastening accordingly has a greater hardness in a region around the grooves than at other regions thereof so that the fastening is resistant to bending or other deformation around the grooves when the spikes are pierced and clenched.
