COLOR SLIDE FASTENER, MANUFACTURING APPARATUS

AND METHOD THEREOF

Technical Field

[1] The present invention relates to a multicolor mixing color slide fastener, manufacturing apparatus and method thereof, and more particularly to a color slide fastener, manufacturing apparatus and method thereof allowing a plurality of clamp teeth each arranged on a pair of support tapes in a length direction and coupled and separated by means of a slider to be molded to have various colors and patterns by irregularly mixing various colors, that is, at least two colors and arranged on the support tapes. Background Art

[2] In general, a slide fastener has been widely applied to various products, such as clothing, bags, etc., wherein the slide fastener is constituted to be used as an open and close means by coupling and separating a plurality of clamp teeth each attached to a pair of support tapes (a cloth tape) along a length direction by means of a slider.

[3] Generally, in such a slide fastener, the support tape is formed of a cloth such as fabrics, the single clamp tooth and the slider are formed of synthetic resin or metal, and the support tape, the single clamp tooth, and the slider each is formed of a single color and a single pattern.

[4] In such a conventional slide fastener, since the support tape and the single clamp tooth are formed of a single color and a single pattern, the pattern thereof is significantly different from the pattern of a ground paper so that pattern interrupting portions occur. Therefore, the conventional slide fastener is not suit the design and color sense of clothing, bags and portable products attached therewith so that unbalance pattern and design occur.

[5] As a result, it has the problems that various patterns and colorful fashion can not be achieved, personality can not be expressed, design sense can be damaged, and degree of freedom in a design can be restricted.

[6] Accordingly, as the products using the slide fastener becomes various and the field using this becomes wide, there is ever increasing a demand for a color slide fastener having various colors and peculiar designs.

[7] The applicant created a color slide fastener having a single clamp tooth of various colors by heating, transporting, and injecting molding material of various colors in a spaces separated from each other in order to solve the problems and filed it as Korean Patent Application No. 1998-50581.

[8] Such a color slide fastener is constituted to allow a plurality of clamp teeth fixed on a support tape to form a multi colors or a combination of a group of separate colors, wherein the clamp teeth is formed by means of an injection molding to have various colors, that is, at least two colors.

[9] FIG. 1 is plan view showing one example of a conventional color slide fastener. In the drawing, each of clamp teeth 2; 2a, 2b, 2c, 2d, 2e, 2f formed on a support tape 1 has different colors and one, a pair, or a predetermined number of the clamp teeth 2 are arranged to be sequentially repeated.

[10] Such a conventional slide fastener has the clamp teeth of various colors, making it possible to prevent the generation of pattern interrupting portions and variously express the design and color sense of clothing, bags, and portable products.

[11] FIG. 2 is a photograph taking a real product of a conventional color slide fastener, wherein each of the clamp teeth is constituted to have different colors, such green, orange, blue, etc.

[12] However, in the conventional color slide fastener, since the colors of the clamp teeth 2 are not continued naturally and each of the clamp teeth 2a, 2b, 2c, 2d, 2e, 2f is arranged by color to form a predetermined pattern, it has the problem that color are interrupted in a portion adjacent other color to form the interrupted pattern.

[36] For example, in FIG. 3, when the color of a first single clamp tooth 20a is red and the color of a third single clamp tooth 20c is yellow, a second single clamp teeth 20b formed between the first single clamp tooth 20a and the third single clamp tooth 20c is approximately orange generated by means of the mixing of red and yellow. Since the mixing of colors as above is irregular, colors more approaching red or yellow are variously represented, making it possible to represent indeterminate colors and patterns.

[37] The accompanying FIGs. 4 and 5 are photographs showing a plan and a bottom with respect to a real thing of a multicolor mixing color slide fastener manufactured according to the embodiment of the present invention. Although the clamp teeth 20 have various colors, it does not form an interrupted pattern of colors but obscurely mixes boundary lines or irregularly mixes various colors by means of the mixing of the injected colors, making it possible to generate indeterminate colors and patterns.

[38] The multicolor mixing color slide fastener allows the clamp teeth 20 to naturally represent various colors so that it can be applied to clothing in which various colors are naturally mixed, for example, clothing or bags on which a spotty pattern, a vivid floral pattern print, etc. are printed, making it possible to totally improve design sense.

[39] Herein, it can mold the clamp teeth 20 to have various colors as well as mold each of the single clamp teeth 20a, 20b, 20c to have at least two colors. When molding the single clamp teeth 20a, 20b, 20c to have different colors on the upper and lower thereof, both surfaces of the fastener are represented with different colors, making it possible to apply them to clothing using both surfaces.
