Description

[Detailed Description of the Invention] The present invention relates to a wall structure of a synthetic resin tube body, and its purpose is to further enhance the decorative effect of pearl essence.

In order to enhance the decorative effect of tube bodies made of thermoplastic synthetic resin, a method has traditionally been used in which pearl essence is mixed into the synthetic resin material to create a pearlescent appearance on the exterior of the molded tube body. .

The pearl decoration effect of this synthetic resin product is
It appears as a faint shine, so if you apply pearl decoration to the entire surface of the product, the entire surface of the product will be decorated with pearls almost uniformly, and the shine will not be emphasized. In some cases, the pearl decoration effect was hardly visible.

In addition, this pearl decoration effect, as mentioned above,
Since it appears due to the reflective action of the pearl essence located on the surface of the synthetic resin product, the shine is flat and has a good effect.

The present invention was devised to eliminate the above-mentioned conventional drawbacks and dissatisfaction. When a curved surface is formed by combining flat surfaces, the inclination angle of the synthetic resin product surface with respect to the incident light changes digitally. And, by making the reflected light from the pearl essence pass through a transparent body that creates a crystal effect, it can be seen, thereby emphasizing the brilliance caused by the pearl decoration effect and obtaining a deep brilliance. It is.

An embodiment of the present invention will be described below with reference to the drawings.

The tube body according to the present invention includes an inner tube 1 made of thermoplastic synthetic resin mixed with pearl essence and having a polygonal tube shape, and an outer tube made of transparent synthetic resin and having a linear cylindrical shape inscribed with the inner tube 1. 4, it has a double wall structure.

In the case of the illustrated embodiment, the inner cylinder 1 is formed into a regular polygonal (16-sided) cylinder shape, and is twisted around its central axis, and its surface 2 and ridge line 3 are formed into a spiral shape. has been done.

The outer cylinder 4 is inscribed with the inner cylinder 1.
The inner cylinder 1 is inscribed in the outer cylinder 4 to the extent that each ridge line 3 of the inner cylinder 1 lightly contacts the inner circumferential surface of the outer cylinder 4.

Therefore, a narrow gap is formed between the inner peripheral surface of the outer cylinder 4 and the surface 2 of the inner cylinder 1.

Therefore, in the tube body according to the present invention, when the inner tube 1 and the outer tube 1 are assembled, each ridgeline 3 of the inner tube 1 is in contact with the outer tube 4, as is clear from FIG. , the ridgeline 3 is visible as it is through the outer cylinder 4, while each surface 2 of the inner cylinder 1
A gap is formed between the outer cylinder 4 and the outer cylinder 4, and while the surface 2 is a flat surface, the portion of the outer cylinder 4 facing the surface 2 has an arcuate convex wall structure. Therefore, the reflected light beam at the surface 2 is subjected to an optical effect by the outer tube 4 portion located opposite to this surface 2.
In other words, the surface 2 is refracted under the action of a prism, and due to the lens effect caused by this refraction, the surface 2 is viewed in a deep state.

In addition, since the angle of each surface 2 is changed stepwise, even if the surfaces 2 are adjacent to each other, the direction of reflection of incident light from a certain direction will be greatly different. Therefore, in a state where any surface 2 strongly exhibits a pearl decoration effect, the surfaces 2 on both sides almost exhibit a pearl decoration effect because the irradiation direction of the reflected light from this surface 2 is greatly shifted. Therefore, the pearl decoration effect on the above-mentioned arbitrary surface 2 becomes more emphasized.

In this way, in the tube body according to the present invention, the inner tube 1 made of synthetic resin material mixed with pearl essence is molded into a polygonal tube shape, so that the angle of the outer peripheral surface of the inner tube 1 relative to the viewer can be adjusted digitally. In other words, the pearl decoration changes discontinuously, and as a result, a large difference occurs in the pearl decoration effect that appears on adjacent surfaces 2, and the pearl decoration is emphasized. The lens effect of the outer tube 4 made of transparent synthetic resin makes it possible to obtain a deep pearl decoration.The tube body according to the present invention has, for example, a mouth tube at the upper end, as shown in the figure. It is used as a commonly known tube container with an integrated head.

As is clear from the above description, the tube body according to the present invention can emphasize the pearl decoration effect that appears on the inner tube 1, and can also make the pearl decoration that appears deep. , and its simple structure makes it easy to mold.
Furthermore, since it has a double wall structure, it has many excellent effects such as being able to obtain sufficient mechanical strength.
