Fastener for brassier or brassier-like garment, a manufacturing method thereof and a brassier or brassier-like garment using such a fastener

Abstract

Right and left fastener parts attached to the right and left ends of a brassier strap. The male fastener part comprises a male tape piece, which is cut out from a male cloth tape on which at least one row of synthetic resin male snap buttons is formed and fastened in such a way that there is at least one button per row. The female fastener part comprises a female tape piece, which is cut out from a female cloth tape on which at least two rows of synthetic resin female snap buttons are formed and fastened in such a way that there is at least one button per row. The male snap button has an engagement protrusion that extends directly from the cloth tape rather than from a base.

         2 . A fastener according to  claim 1 , in which the upper and lower ends of the male tape piece and female tape piece, i.e., the parts at which the tapes are cut, are ultrasonically welded, and free ends of the respective tape pieces and sections adjacent to the snap buttons are sewn up.  
     
     
         3 . A fastener according to  claim 1 , in which reinforcement base cloths are provided under the male tape piece and the female tape piece respectively.  
     
     
         4 . A fastener according to any one of  claims 1  to  3 , in which the exteriors of the male snap button and the female snap button are ring-shaped when viewed from either the face side or the back side.  
     
     
         5 . A fastener for a brassier or brassier-like garment equipped with a strap, comprising right and left fastener parts attached to the right and left ends of the strap, in which: 
 the male fastener part comprises a male cloth tape on which at least one row of synthetic resin male snap buttons is formed and fastened in such a way that there is at least one button per row;    the female fastener part comprises a female cloth tape on which at least one row of synthetic resin female snap buttons is formed and fastened in such a way that there is at least one button per row; and    the male fastener part and the female fastener part have directionality for engagement and disengagement.    
     
     
         6 . A fastener for a brassier or brassier-like garment according to  claim 5 , in which: 
 the male snap button has an engagement protrusion provided with an engagement-protrusion-forming slant surface, an engagement socket and a base, said engagement protrusion extending diagonally upwards from the face side of the base in the direction of the engagement socket, while a slant surface, which is parallel with the protrusion-forming surface, is formed on the face side of the engagement socket of the base; and    the female snap button has an engagement protrusion provided with an engagement-protrusion-forming slant surface, an engagement socket and a base, said engagement protrusion extending diagonally downwards from the face side of the base in the direction of the engagement socket, while a slant surface, which is parallel with the protrusion-forming slant surface, is formed on the face side of the engagement socket of the base, creating, together with the engagement socket, a space for receiving the engagement protrusion of the male snap button when the male and female snap buttons are engaged.    
     
     
         7 . A method for manufacturing a fastener for a brassier or brassier-like garment equipped with a strap, said fastener comprising right and left fastener parts attached to the right and left ends of the strap, in which: 
 from a male cloth tape, on which a plurality of rows of synthetic resin male snap buttons are formed and fastened in such a way that there is at least one button per row, a tape piece having at least one row is cut out to make the right fastener part;    from a female cloth tape, on which a plurality of rows of synthetic resin female snap buttons are formed and fastened in such a way that there is at least one button per row, a tape piece having at least two rows is cut out to make the left fastener part;    the male snap button has an engagement protrusion that extends directly from the cloth tape rather than from a base; and    the left and right fastener parts are attached to the right and left ends of the strap of the brassier or brassier-like garment.    
     
     
         8 . A method for manufacturing a fastener for a brassier or brassier-like garment equipped with a strap, said fastener comprising right and left fastener parts attached to the right and left ends of the strap, in which: 
 from a male cloth tape, on which a plurality of rows of synthetic resin male snap buttons are formed and fastened in such a way that there is at least one button per row, a tape piece having at least one row is cut off to make the right fastener part;    from a female cloth tape, on which a plurality of rows of synthetic resin female snap buttons are formed and fastened in such a way that there is at least one button per row, a tape piece having at least two rows is cut off to make the left fastener part; and    the male snap button and female snap button have directionality for engagement and disengagement.    
     
     
         9 . A method according to  claim 7  in which the male snap button is formed by inserting a cloth tape of a coarse texture that allows the permeation of molten resin under a forming pressure between an upper die and a lower die, which are provided with a space for forming the fastener, then the part of the cloth tape that is in the hollow inside the engagement protrusion of the male snap button is clamped by the upper and lower dies, after which synthetic resin is injected into the space for forming, thereby integrating the front part and the back part of the male snap button formed on either side of the cloth tape with the synthetic resin that permeates through the cloth tape.  
     
     
         10 . A method according to  claim 7  in which the female snap button is formed by inserting a cloth tape of a coarse texture that allows the permeation of molten resin under a forming pressure between an upper die and a lower die, which are provided with a space for forming the fastener, then the part of the cloth tape that is in the engagement socket of the female snap button is clamped by the upper and lower dies, after which synthetic resin is injected into the space for forming, thereby integrating the front part and the back part of the female snap button formed on the cloth tape with the synthetic resin that permeates through the cloth tape.  
     
     
         11 . A brassier or brassier-like garment having snap buttons according to any one of  claims 1  to  6 .
