Title: Color mark structure applying on rubber product and method for making the same

Description:
FIELD OF THE INVENTION 
     The present invention relates to a color mark, and more particularly to a color mark structure applying on rubber product and method for making the same. 
     BACKGROUND OF THE INVENTION 
     Because the vulcanized rubber is capable of flowing and strengthening, the mark unit with brand may be blurred when the general mark unit is attached/adhered on the rubber product. Therefore, the color mark unit attached/adhered on the tire (for cars, trucks, buses, and etc.) is hard to show the brand mark clearly. 
     The conventional method for making color mark may reference to TW patent no. 1242758. It disclosed a method and end product of color mark on tensile rubber products. The steps of the method comprises material drawing step (step A), coating step (step B), attaching step (step C), vulcanizing step (step D), adhering step (step E), and cutting step (step F). The vulcanized rubber or the compounding rubber which is not vulcanized is drawn to be the raw material. A color mark unit is attached on the raw material with an adhesive. And then, the color mark unit and the raw material are totally attached together after they are vulcanized. A paste is coated on the side of the raw material opposite to the color mark unit so as to attach a protective film. Therefore, the rubber product may show color mark with brand thereon. 
     According to above mentioned method, the protective film of the end product after being cut is peeled off so as to attach on the rubber tire, such as for bicycles, motorcycles, cars, trucks. After pressurizing and vulcanizing, the raw material and the rubber tire are become one piece. However, the position and the angle of the raw material relative to the rubber product after pressurizing and vulcanizing are not fine-tuned. If the error happens while vulcanizing, the tire which may be high price is scrapped so that the defect rate and the cost become higher. 
     In view of the foregoing circumstances, the inventor has invested a lot of time to study the relevant knowledge, compare the pros and cons, research and develop related products. After quite many expetireents and tests, the “color mark structure applying on rubber product” of this invention is eventually launched to improve the foregoing shortcomings, to meet the public use. 
     SUMMARY OF THE INVENTION 
     An object of this invention is providing a color mark structure applying on rubber product. When the pattern shape is attached on the tire, the position and the angle of the pattern shape may be fine-tuned due to directly be adhered by the adhesive. Compared to the conventional method, the transfer paper and the cellophane are vulcanized first and then attached/adhered to the tire. It may not cause the high-price tire to be scrapped and further may lower the defect rate. Additional, the use of the adhesive may prevent the pattern shape from peeling off. 
     To achieve above objects, a color mark structure applying on rubber product may comprise a cellophane; and a transfer paper, arranged on the cellophane, and a predetermined color or a predetermined pattern with a predetermined color is printed thereon by screen printing; wherein the transfer paper having the predetermined color or the predetermined pattern with the predetermined color and the cellophane are attached on the rubber product, and the upper and lower sides of the transfer paper are respectively connected with the cellophane and the rubber product. 
     In some embodiments, a size of the transfer paper and the cellophane which are attached together is cut to fit a machining size of a vulcanizer for vulcanizing. 
     In some embodiments, the transfer paper and the cellophane which are attached together and vulcanized are cut according to a predetermined shape or the predetermined pattern to form a pattern shape by laser cutting or a cutting machine. 
     In some embodiments, the pattern shape is attached on a tire by an adhesive which at least includes Ethyl cyanoacrylate. 
     To achieve above objects, a method for making the color mark structure is disclosed. The steps of the method may comprise: step S1: arranging a transfer paper on a cellophane and printing a predetermined color or a predetermined pattern with a predetermined color thereon by screen printing; step S2: cutting a size of the transfer paper and the cellophane which are attached together to fit a machining size of a vulcanizer for vulcanizing; step S3: putting the transfer paper and the cellophane which are attached together on a rubber product and peeling off the cellophane; step S4: vulcanizing the transfer paper and the rubber product in a vulcanizer; step S5: cutting the transfer paper and the cellophane which are attached together and vulcanized according to a predetermined shape or the predetermined pattern to form the pattern shape which includes shapes and words by laser cutting or a cutting machine; and step S6: attaching the pattern shape on a tire by an adhesive which at least includes Ethyl cyanoacrylate. 
     Further features and advantages of the present invention will become apparent to those of skill in the art in view of the detailed description of preferred embodiments which follows, when considered together with the attached drawings and claims.
