BACKGROUND1. Field of Invention
The present invention relates to a fastener. More particularly, the present invention relates to a touch fastener with a firm and stable fastening effect.
2. Description of Related Art
Touch fasteners are quite common fasteners used to attach one article with another article in our daily life and are also popular.
With reference to
With reference to
First, using stitches to attach both sides 100 and 100′ of the touch fastener on the interior 141 of the article 140 causes unsightly exterior 142 of the article 140.
With reference to
Furthermore, edges 101 of the loop side 100 and the hook side 100′ may be raised in a direction opposite to the article 140 by the stress caused by the stitches 150. Therefore, the raised edges 101 of the loop side 100 and the hook side 100′ imposes potential hazards that a person may be injured while the person holds, assembles or carries the article 140.
Besides, corners 102 between the edges 101 are also raised and pointed regardless of using single-needle or multi-needle stitches to attach the touch fastener. The potential hazards of injury are still not being addressed.
Moreover, processing speed for stitching the touch fastener is slow, and mistaken stitches are easily occurring regardless of using single-needle or multi-needle stitches. The manufacturing yield is decreased.
With reference to
With reference to
With reference to
Besides, applications of the conventional touch fastener, such as shoe fastener, clothing fastener, carpet fastener, vehicle carpet fastener, mat fastener, parcel fastener, backpack fastener, hat fastener or sofa pad fastener etc. need neat and good-looking appearance. The exposed stitches 150 depress the appearance of the application. Besides, mistaken stitches may occur so that the yield and the quantity of production are decreased.
Therefore, there is a need to provide an improved touch fastener to mitigate or obviate the aforementioned problems.
SUMMARYAn object of the present invention is to provide a touch fastener with a fastening layer and an adhesive that are arranged in a same surface. The touch fastener is convenient to use to bond articles together, and is easy and quick to be attached to the articles with a robust and strong attachment and without resulting any raised edges.
Another object of the present invention is to provide a touch fastener that uses an adhesive to attach it on the articles to prevent any mistakes in processing and decreases the defective rate of processing.
A touch fastener comprises a base, a fastening layer and an adhesive. The base has a first surface and a second surface opposite to the first surface. The fastening layer is formed on the first surface. The adhesive is attached to the first surface adjacent to the fastening layer. When attaching the touch fastener to an article, the adhesive is melted by heat and pressure welding, such as ultrasonic welding or high frequency welding to stick the touch fastener on the article. Since only the first surface with melted adhesive can stick the article, the mistakes in processing operations are prevented. Further, the adhesive can firmly stick the touch fastener on the article to eliminate any raised edges that may impose potential injures.
In addition, a robust and strong connection between the touch fastener and the article can be obtained because of the exact attachment by the adhesive.
Since the mistakes in processing operations are avoided, defective rate of manufacture can be decreased that means the yield can be improved.
These and other features, aspects, and advantages of the present invention will become better understood with regard to the following description, appended claims, and accompanying drawings where:
Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

The touch fastener in accordance with the present invention has several advantages.
First, the touch fasteners 200,200′, and 300 of the abovementioned embodiments arrange the adhesives 230 and 330 adjacent to the fastening layer 220. Thus, when using the touch fasteners 200,200′ and 300 to bind articles, the adhesives 230 and 330 are melted and stuck to the articles with heat and thermo pressure method (such as ultrasonic welding or high frequency welding). The adhesives 230 and 330 are exactly stuck to the articles so as to eliminate raised edges of the touch fastener. The potential hazards of injuring hands are prevented. In addition, the melted adhesive 230 and 330 can help stabilize the connection between the interior structure of the pressed fastening layer 211 and the base 210. Thus, the adhesive 230 and 330 quickly and stably stick the touch fastener on the articles to render a robust and stable connection between the touch fastener and the base 210.
Second, the adhesives 230 and 330 and the fastening layers 220 and 320 can be arranged on the same surface of the base 210 and 310, either on the first surface 211 or on the second surface 212. Only the adhesives 230,330 need to be welded by heat and pressure welding so that mistaking operations can be avoided. The touch fastener prevents mistakes as attaching the touch fasteners to the articles so that the yield has been improved.
