Tpu rain boot

Abstract

The TPU rain boot has a sole section and a foot section. The sole section has a contour edge. The foot section is made of TPU and mounted on the contour edge of the sole section by a thermal compressing process and has a front slice, two side slices and a top opening. The front slice is mounted on the contour edge of the sole section and covers a tiptoe part of the sole section. The side slices are mounted on the sole section and surround a heel part of the sole section. Each side slice has a front end overlapped and mounted on the front slice and a rear end overlapped and mounted on the rear end of the other side slice with a thermal compressing process. The top opening is formed and surrounded by the side slices.

1 . A TPU (Thermoplastic Polyurethane) rain boot comprising:
 a sole section having a contour edge, a tiptoe part and a heel part; and   a foot section made of TPU and mounted on the contour edge of the sole section with a thermal compressing process and having
 a front slice mounted on the contour edge of the sole section with a thermal compressing process and covering the tiptoe part of the sole section; 
 two side slices mounted on the sole section with a thermal compressing process and surrounding the heel part of the sole section, and each side slice having
 a front end overlapped and mounted on the front slice by a thermo compression molding and formed a font seal; and 
 a rear end overlapped and mounted on the rear end of the other side slice by a thermo compression molding and formed a rear seal; and 
 
 a top opening formed and surrounded by the side slices. 
   
     
     
         2 . The TPU rain boot as claimed in  claim 1 , wherein
 the foot section has a top edge defined around the top opening; and   a shank section is tubular and mounted on the top edge of the foot section with a thermal compressing process.   
     
     
         3 . The TPU rain boot as claimed in  claim 2 , wherein the shank section has two shank slices, and each shank slice having
 a bottom end overlapped and connected with the top edge of the foot section with a thermal compressing process and formed a bottom seal; and   two sides respectively overlapped and connected with the two sides of the other shank slice with a thermal compressing process to shape the shank tubular and form two side seals.   
     
     
         4 . The TPU rain boot as claimed in  claim 1 , wherein a soft layer is sewed on an inner surface of the foot section. 
     
     
         5 . The TPU rain boot as claimed in  claim 2 , wherein a soft layer is sewed on an inner surface of the foot section. 
     
     
         6 . The TPU rain boot as claimed in  claim 3 , wherein a soft layer is sewed on an inner surface of the foot section and an inner surface of the shank section.
