## Background
CROSS REFERENCE
The present application is a division of U.S. application Ser. No. 13/404,084 filed on Feb. 24, 2012, now U.S. Pat. No. 8,894,788.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a decorative element and, more particularly, to a decorative element comprising a TPU film and methods for forming it.
2. Description of the Related Art
The design of commercial products has varied enormously. In addition, fashion has often dictated many design elements, such as products having uneven outsides, patterns, or trademarks sewn on the outside of products to make a certain style look attractive. Presently, the ornament sewn on the outside of products requires a large amount of manual labor for sewing.
Further, the ornament must previously reserve the outlet seam to provide a space to be sewn on the outside of products, so that a small size or complex ornament is hard and inconvenient to be sewn on the outside of products and increases manufacturing costs. Moreover, the ornaments sewn on the outside of products will form sewing traces arranged on the outside to make the products look promiscuous and unattractive.
Additionally, when the outside of the product is non-planar, processors cannot paste the protecting film onto the ornaments and outside of the product easily, and air bubbles will be formed between the protecting film and the outside of the product easily too.
The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.
SUMMARY OF THE INVENTION
According to the present invention, the main purpose is to provide a method for producing a decorative element includes the steps of: (a) preparing a thermoplastic polyurethane (abbreviated TPU) film, at least one ornament, and a releasing film, which has been coated with a glue layer on a plane thereof; (b) disposing the plane of the releasing film coated with the glue layer facing the ornament; (c) arranging the ornament located between the TPU film and the releasing film to form a stacked array; and (d) hot pressing the stacked array.
An advantage of the method for producing the decorative element according to the present invention is that the TPU film, the ornament, and the releasing film are connected with each other by hot pressing, thereby allowing the decorative element to be processed accurately, conveniently and in a cost-saving manner.
Another advantage of the decorative element according to the present invention is that the decorative element can be coupled to a desired place easily, quietly, and conveniently.
An additional advantage of the decorative element according to the present invention is that the TPU film is transparent and pervious to light, so that the ornament can be seen for aesthetic enjoyment.
Other objects, advantages, and new features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanied drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be described through detailed illustration of embodiments referring to the drawings.
Referring to FIG. 1, a method for producing a decorative element includes the steps of: (a) preparing a thermoplastic polyurethane (abbreviated TPU) film, at least one ornament, and a releasing film coated with a glue layer on a plane thereof; (b) disposing the plane of the releasing film coated with the glue layer facing the ornament; (c) arranging the ornament located between the TPU film and the releasing film to form a stacked array; and (d) hot pressing the stacked array.
Referring to FIGS. 2 through 3, there is shown a decorative element 1 in accordance with the present invention. The decorative element 1 is adapted for coupling with a desired place.
Step (a): preparing a roll of TPU film 10, at least one roll of ornament 20, and a roll of releasing film 30 coated with a glue layer 40 on a plane thereof. The TPU film 10 is transparent and pervious to light. The ornament 20 may be constructed of cotton thread or other decorative materials. The releasing film 30 includes first and second planes 31 and 32 disposed at two opposite ends thereof. The first plane 31 is adapted to be coated with the glue layer 40 and to face the TPU film 10.
Step (b): disposing the first plane 31 of the releasing film 30 coated with the glue layer 40 facing the ornament 20.
Step (c): arranging the ornament 20 located between the TPU film 10 and the first plane 31 to form a stacked array. The ornament 20 is located between the TPU film 10 and the first plane 31 of the releasing film 30 and contacted with the glue layer 40, so the ornament 20 is enclosed securely between the TPU film 10 and the releasing film 30 to form a stacked array.
Step (d): hot pressing the stacked array. The stack array is hot pressed by a hot pressing machine 2 to form the decorative element 1 to avoid air bubbles formed between the TPU film 10 and the releasing film 30. Additionally, the TPU film 10 is transparent and pervious to light, so that the ornament 20 can be seen for aesthetic enjoyment.
Referring to FIGS. 4 through 5, the TPU film 10 defines a first width W1. The ornament 20 defines a second width W2. The releasing film 30 defines a third width W3. The first width W1 is equal to the third width W3 generally, and the second width W2 is less than the third width W3, so that the TPU film 10 and the releasing film 30 coated with the glue layer 40 contact each other with a big contact area resulting in the ornament 20 enclosed securely between the TPU film 10 and the releasing film 30. Moreover, the releasing film 30 can be stripped from the glue layer 40, so that the decorative element 1 is adapted for coupling with a desired place easily and conveniently.
Referring to FIGS. 6 through 8, they respectively show the decorative element 1 to be applied to a shoe 3 and luggage 4, with the ornament 20 shown in FIGS. 6 through 8 consisting of multiple, spaced threads free of interconnection therebetween. The decorative element 1 is adapted for coupling with a desired place such as a vamp of a shoe 3 or outside of luggage 4 easily, quietly, and conveniently, and can be adjustable with quantity and configuration.
In view of the foregoing, an advantage of the method for producing the decorative element 1 according to the present invention is that the TPU film 10, the ornament 20, and the releasing film 30 are connected with each other by hot pressing, thereby allowing the decorative element 1 to be processed accurately, conveniently and in a cost-saving manner.
Another advantage of the decorative element 1 according to the present invention is that the decorative element 1 can be coupled to a desired place easily, quietly, and conveniently.
An additional advantage of the decorative element 1 according to the present invention is that the TPU film 10 is transparent and pervious to light, so that the ornament 20 can be seen for aesthetic enjoyment.
Thus since the invention disclosed herein may be embodied in other specific forms without departing from the spirit or general characteristics thereof, some of which forms have been indicated, the embodiment described herein is to be considered in all respects illustrative and not restrictive. The scope of the invention is to be indicated by the appended claims, rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
