Benefits of technology

[0009]The main objective of the present invention is to provide a TPU rain boot with a foot section

Problems solved by technology

However, the conventional rain boot is made of plastic by injection molding by a mold and is heavy and not easy to change the shape.
Consequently, the conventional rain boot is unvaried, cumbersome and unaesthetic.
Furthermore, the conventional rain boot has no soft inner pad in the rain boot and causes uncomfortable feeling to a user.
However, the foot section 62 and the shank section 63 of the conventional rain boot are sewed with each other by the sewing line and cause multiple needle holes.
Furthermore, the conventional rain boot cannot be implemented with a soft layer that is sewed on an inner surface of the rain boot because the soft layer causes multiple needle holes in the rain boot and permeable to water into the rain boot.

Embodiment Construction

[0019]With reference to FIG. 1, a TPU rain boot in accordance with the present invention has a sole section 10, a foot section 20, a shank section 30 and a soft layer 40. The sole section 10 is shaped by a mold and has a contour edge, a tiptoe part, a heel part and a heel 11. The heel 11 is disposed at the heel part and protrudes from a bottom of the sole section 10. The heel 11 may be shaped in cylinder or taper and be a high heel or a low heel to improve aesthetic appeal of the TPU rain boot.

[0020]The foot section 20 is made of TPU (Thermoplastic Polyurethane) and thermoplastic. The TPU has many useful properties as elasticity, tenacity, abrasion and waterproof. The foot section 20 is mounted on the contour edge of the sole section 10 with a thermal compressing process or by a high frequency equipment to form a foot containing space and a bonding edge. The bonding edge is formed along the contour edge of the sole section 10 and is continued and sealed to provide a waterproof funct...

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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a boot, and more particularly to a TPU (Thermoplastic Polyurethane) rain boot with a foot section connected to a sole section with a thermal compressing process to provide a waterproof function.[0003]2. Description of Related Art[0004]With reference FIG. 5, a conventional rain boot is made of plastic by injection molding, and is implemented as a sole section 51, a foot section 52 and a shank section 53. The sole section 51 has a contour edge. The foot section 52 is formed on and protrudes from the contour edge of the sole section 51. The foot section 52 is hollow and has a foot containing space. The shank section 53 is formed on and protrudes from the foot section 52, shapes tubular and has a top opening communicating with the foot containing space of the section 52.[0005]However, the conventional rain boot is made of plastic by injection molding by a mold and is heavy and not easy to ch...
