       7 . The improved laminated pocket zipper with a zipper-lip of  claim 6 , wherein a second layer of fabric is affixed underneath the upper fabric in the hollow space.  
   
   
       8 . The improved laminated pocket zipper with a zipper-lip of  claim 3 , wherein the first thermally meltable compound is a thermally meltable polyurethane resin in form of a glue film.  
   
   
       9 . The improved laminated pocket zipper with a zipper-lip of  claim 3 , wherein the second thermally meltable compound is a thermally meltable polyurethane resin in form of a glue film.  
   
   
       10 . The improved laminated pocket zipper with a zipper-lip of  claim 1 , wherein the reinforcing member is made of polyurethane (PU).  
   
   
       11 . The improved laminated pocket zipper with a zipper-lip of  claim 2 , wherein the upper fabric, the first and second zipper tapes are made of impregnated woven fabric.  
   
   
       12 . The improved laminated pocket zipper with a zipper-lip of  claim 2 , wherein the upper fabric, the first and second zipper tapes are made of non-impregnated woven fabric.  
   
   
       13 . The improved laminated pocket zipper with a zipper-lip of  claim 2 , wherein the upper fabric, the first and second zipper tapes are made of knit man-made fabric.  
   
   
       14 . The improved laminated pocket zipper with a zipper-lip of  claim 1 , wherein the upper fabric is a shell of the garment.  
   
   
       15 . A method of making a laminated pocket zipper with a zipper-lip, comprising the steps of: 
 a. providing an upper fabric;    b. placing a thermally meltable compound underneath the upper fabric;    c. cutting a slit of a first length through the upper fabric and the thermally meltable compound to divide the upper fabric and the thermally meltable compound each into a base section and a flap section, the flap section having a free edge and an anchor portion;    d. placing a first zipper tape of a second length underneath the anchor portion of the flap section of the upper fabric and substantially parallel to the slit;    e. placing a second zipper tape of the second length underneath the base section of the upper fabric and substantially parallel to the slit in such a manner that the second zipper tape extends beyond the slit to be engageable with the first zipper tape;    f. straddling a reinforcing member of the first length over the free edges of the flap section and the thermally meltable compound; and    g. heat-pressing the upper fabric along the slit with a thermal pressing machine.
