Description SPANGLE
Technical Field
[1] The present invention relates, in general, to corn spangles and, more particularly, to corn spangles attached to clothes, footwear, bags, belts, scarves, headgear and a variety of textiles, to be used for decoration. Background Art
[2] Generally, spangles are used in order to decorate a variety of textiles, clothes, bags, headgear and so on. Most of the spangles are formed by processing a reflective body of a thin film, and then using them on clothes, handbags, and shoes, etc. as accessories for decoration. Spangles are mostly flat and have round, hexagonal or plate shapes, the sizes of which are generally 0.4cm to 0.5D in diameter. However, there are also large spangles whose diameter is close to 2D. Most spangles have through holes for sewing through the central parts thereof. Thus, the spangles are usually threaded through the holes and fixed to objects to which the spangles are attached (hereinafter referred to as "attachment objects") such as textiles or clothes.
[3] However, as conventional spangles are manufactured with a thin film, they are disadvantageous in that they do not exhibit a sufficient glittering effect when viewed from lateral angles. That is, since the conventional spangles are not three-dimensional, the glittering effect thereof is limited. For this reason, the conventional spangles have difficulty making brilliant and beautiful impressions.
[4] In addition, since the conventional spangles are threaded on and fixed to cloths by a sewing thread, to do such a job is very inconvenient and a long period of time is consumed in doing the job. Even after they are fixed onto an attachment object, the sewing thread is inclined to be easily broken when a frictional force, e.g., one caused by laundering or washing, is externally applied thereto, such that the spangles become detached from the attachment object.
[5] Korean Patent No. 367926 discloses a spangle manufactured so as to provide an effect of reflecting brilliant light, by having various illuminating surfaces formed thereon in order to enhance the glittering effect.
[6] However, this spangle still retains the problem of the conventional fixing method based on the sewing as described above, and the effect of reflecting light is not maximized because the reflecting area of the illuminating surfaces is not so wide when viewed from the lateral angles. Disclosure of Invention Technical Problem
[7] Accordingly, the present invention has been made keeping in mind the above problem occurring in the prior art, and an object of the present invention is to provide a corn spangle having a hemispherical shape so as to maximize the light reflecting effect and a hot-melt adhesive layer formed on the bottom surface thereof in order to allow it to be easily attached to an attachment object.
[8] Another object of the present invention is to provide a hemispherical corn spangle whose edges are sharp so that the sharp edges firmly penetrate into an attachment object when the spangle is attached to the attachment object, thereby preventing it from easily becoming detached. Technical Solution
[9] In order to accomplish the above objects, the present invention provides a corn sp angle, characterized in that it comprises: a base film layer, both surfaces of which are treated by corona discharge, and a top surface of which reflects light, and a hot melt adhesive layer formed on a bottom surface of the base film layer, whereby the corn spangle generally has the shape of a hemisphere, whose top surface is convex and bottom surface is concave.
[10] The corn spangle further comprises: a glittering layer, provided by applying glittering materials on the top surface of the base film layer, and a transparent coating layer, provided by applying a transparent resin paint so that the applied glittering materials are firmly attached.
[11] In the corn spangle, the edge of the hemisphere is substantially shaped as a
"λ"-shape viewed in a section, both ends of which are sharp, so that both ends are widened and can firmly penetrate into an attachment object when the spangle is attached to the attachment object with pressure.
[12] The objects of the present invention described above will be further clarified from the embodiments of the present invention which will be described later with reference to the accompanying drawings.
Advantageous Effects
[13] According to the present invention, since a corn spangle has a hemispherical shape, the reflective power is maximized to thereby obtain an excellent glittering effect. In addition, since the spangle is directly attached to an attachment object as a hot melt adhesive layer formed on the bottom surface thereof is melted, it is easy and quick to attach it to the attachment object, thereby improving the operational efficiency.
[14] When the corn spangle according to the present invention is attached to an attachment object with pressure and while applying heat to the hot melt adhesive layer, both ends of the lower edge are widened and firmly penetrate into the attachment object, thereby having improved attaching force and fixing force. Therefore, even if
external friction is applied, the spangle is not detached from the attachment object, thereby being effective in continuously maintaining its original state. Brief Description of the Drawings

[16] FIG. 2 is a sectional view illustrating a corn spangle according to a second embodiment of the present invention;
[17] FIG. 3 is a sectional view illustrating a corn spangle according to a third embodiment of the present invention; and
[18] FIG. 4 illustrates a state in which an edge of the spangle securely penetrates into an attachment object in FIG. 3. Best Mode for Carrying Out the Invention
[19] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a sectional view illustrating a corn spangle according to a first embodiment of the present invention, and FIG. 2 is a sectional view illustrating a corn spangle according to a second embodiment of the present invention.
[20] In order to maximize the reflecting effect in all directions, the corn spangle according to the present invention features in a configuration such that it is generally has the shape of a hemisphere, whose top surface is convex and bottom surface is concave.
[21] Referring to FIG. 1, the corn spangle according to the first embodiment of the present invention comprises a base film layer 10 and a hot melt adhesive layer 20 formed on the bottom surface of the base film layer 10.
[22] It is preferable that the top surface of a film forming the base film layer 10 reflects light, and the surface thereof is desirably treated by corona discharge. Here, the corona discharge treatment changes the surface condition of the film by applying an electric attack or transmitting the laser to the surface of the film, so that fine scratches are formed on the surface of the film and enhance the adhering force. The corona discharge treatment technique is well-known in the related art, and thus, detailed description thereof will be omitted.
[23] As described above, since the base film according to the present invention is treated by corona discharge, the hot melt adhesive layer on the bottom surface retains the well- adhered state. Also, when a separate coating solution is applied on the top surface in order to improve the reflective power, the coating solution can maintain a well-adhered state.
[24] The hot melt adhesive layer 20 is formed by applying a hot melt adhesive on the bottom surface of the base film layer 10 to a predetermined constant thickness and then
drying it. The spangle is attached to an attachment object (P) as the hot melt adhesive is melted when predetermined heat is applied thereto using an ultrasonic fusion machine. There is no special limitation to materials used as hot melt adhesive, but polyester or polyurethane is mainly used.
[25] Here, the attachment object (P) may be any selected from among clothes, footwear, bags, belts, scarves, headgear and a variety of textiles.
[26] Since the corn spangle having the configuration described above has a hemispherical shape, the light reflecting effect of the spangle is excellent from all angles, including front and lateral sides, thereby being capable of maximizing the glittering effect.
[27] In addition, since the hot melt adhesive layer is formed on the bottom surface of the corn spangle and the spangle is directly attached to the attachment object when the hot melt adhesive layer is fused, it is possible to attach the spangle more easily, firmly and beautifully than the conventional method of fastening the spangle using sewing thread. Further, the spangle attached to the attachment object P provides the sense that the spangle and the attachment object are integral, not the sense that they are separated. Accordingly, the external beauty thereof is improved.
[28] The structure of the corn spangle according to the second embodiment of the pr esent invention will be described with reference to FIG. 2.
[29] In the same manner as that described for the first embodiment of the present invention, the corn spangle according to the second embodiment basically comprises a base film layer 10 and a hot melt adhesive layer 20 formed on the bottom surface of the base film layer 10, but it further comprises a glittering layer 30 formed by applying glittering materials to the top surface of the base film layer, and a transparent coating layer 40 formed by applying a transparent resin paint so that the applied glittering materials are firmly attached.
[30] The base film layer 10 and the hot melt adhesive layer 20 are the same as described in the first embodiment described above, and thus, description thereof will be omitted.
[31] The glittering layer 30 is formed by applying glittering materials having the property of efficiently reflecting light, and a variety of colors can be applied to the glittering materials. The glittering materials forming the glittering layer 30 are not specifically limited, but it is preferable that polyester films be mainly used. Preferably, polyester film is printed with colors, and then cut into small particles to then use it.
[32] The transparent coating layer 40 is formed by applying a conventional transparent resin paint, whose components are excellent in adhesion and withstand bending, onto the glittering layer 30 and drying it. This layer is designed to prevent the glittering materials attached on the film from being easily detached by friction with external elements, moisture, etc.
[33] The corn spangle according to the second embodiment of the present invention with the above-described construction has the same effect and operation as the first embodiment described above. In addition, since the glittering layer having various colors and the transparent coating layer are formed, it is possible to produce a design of the spangle more beautifully and freely. And, even if friction from an external element is applied to the glittering layer, the glittering materials are not easily detached since the transparent coating layer protects the glittering layer, thereby continuously maintaining its original state.
[34] Next, a corn spangle according to a third embodiment of the present invention will be described with reference to FIGS. 3 and 4.
[35] The corn spangle according to the third embodiment features that lower edges 12 of the hemispherical spangle substantially have a "λ"-shape in section. These figures show the first embodiment of this spangle described above, but it is applicable to the second embodiment.
[36] Here, the edge 12 substantially having a "λ"-shape is sharp at both ends 12a. Thus, it is desirable that both ends are widened and securely penetrate into the attachment object when the spangle is attached to an attachment object with pressure.
[37] To enhance the adhering force of the "λ"-shaped edge 12, the hot melt adhesive
20-1 may be applied as indicated by a virtual line in FIG. 3.
[38] The corn spangle according to the present embodiment is attached by the hot melt adhesive to an attachment object. Further, when the spangle is attached to the attachment object while applying heat and pressure as illustrated in FIG. 4, both ends of the lower edge of the spangle are widened and the sharp portions deeply penetrate into the attachment object, thereby making it possible to more firmly attach it. Owing to this firm attachment, even if pressure such as friction is externally applied, the spangle is not detached from the attachment object. Other operations and effects of the spangle according to the present embodiment are the same as described above, and description thereof will be omitted. Industrial Applicability
[39] The corn spangles according to the present invention can be usefully applied to bags, clothes, footwear, hair pins, hair bands, headgear, waist belts, fashion accessories, decorative sheets, and patches for clothes, etc.
