Description

TECHNICAL FIELD OF THE INVENTION A manufacturing method of a light-transmissive collar airbag for shoes and a light-transmissive collar airbag for shoes manufactured by the present invention TECHNICAL FIELD

The present invention relates to a method of manufacturing a light-transmissive color airbag for shoes and to a light-transmissive color airbag for shoes manufactured by the present invention. More specifically, a shoe having a visually superior design having a predetermined color and having a light transmissive appearance The present invention relates to a method for manufacturing a light-transmissive color airbag for shoes that can easily produce a light-transmissive color airbag for shoes, and to a light-transmissive color airbag for shoes manufactured thereby.

In general, shoe airbags are widely used in the middle sole of a shoe or under the insole, and are widely used to absorb shocks when walking by cushioning an air chamber in which air is stored therein. These shoe airbags are equipped with pillars for supporting the air chamber as the size of the shoes increases, and the shapes are also variously manufactured, such as round and square, and these shapes cause a visually unique aesthetic feeling to consumers. It is becoming.

A representative example of such a conventional shoe airbag is shown in FIG. 1. 1 is a photograph of a shoe airbag of a conventional transparent color. The conventional shoe airbag shown in FIG. 1 is manufactured to have a transparent color by using a publicly known blow molding or extrusion molding method for displaying a transparent color, and is simply manufactured to perform a shock absorbing function.

However, in recent years, in order to meet a variety of consumer needs in addition to such functionality in consideration of the design aspect, color air bags having various colors have been manufactured and used in shoes. The manufacturing method of the conventional shoe color airbag is divided into two types.

One of the manufacturing methods is to prepare a material in which a dye having a predetermined color is mixed with a material exhibiting a transparent color, and then, manufacture the color airbag for a shoe through the blow molding or compression molding method using the mixed material.

However, the shoe color airbag manufactured as described above has an opaque color, and thus, when the shoe color airbag is mounted on the shoe, the shape of the air chamber and the pillar, which is a unique shape inside the airbag, is not visible, and thus the aesthetics are not so beautiful that the visual appearance is not excellent.

Another manufacturing method is to paint the shoe by spraying or painting a color paint having a predetermined color on a predetermined portion of the surface of the shoe color airbag transparently manufactured to solve the above problems by spraying or painting with a tool such as a spray gun or a brush To produce a color airbag, a shoe color airbag manufactured as such is shown in FIGS. 2 and 3. 2 and 3 are photographs of shoe color airbags in which color paint having a predetermined color is painted on predetermined portions of the surface of shoe airbags of transparent colors, respectively.

However, the shoe color airbags shown in FIGS. 2 and 3 are complicated to manufacture and increase in cost due to the addition of a painting process, and the color paint on the surface is peeled off. Even when painting, the painted part is opaque color, so there is a problem that the aesthetics are not beautiful. In addition, the shoe color airbags for which the painting operation is completed, there is a problem that the raw materials can not be recycled due to the painted color paint if the defects.

On the other hand, in order to solve the problem that the color paint painted on the surface is peeled off recently (Patent Document 1) of the late [prior art document] which paints by injecting color paint into the inner wall of the airbag body through the injection hole communicating with the air chamber Patent registration No. 1025955, "Shoe color airbag manufacturing method" was developed.

However, in the case of Patent Document 1, a color paint injection process must be added, and it is not easy to inject paint through a small injection hole, and there is a problem that uniform painting of the entire inner wall of the airbag body is difficult. In addition, the painted part is not opaque because it is an opaque color, the shoe color airbags for which the painting operation is completed, there is a problem that can not be recycled as well as raw materials.
