Tubular body having decorative layer and method for forming decorative layer on tubular body

Abstract

A tubular body having a decorative layer formed by ink-jet printing which is less prone to be broken by an external force. Tubular structures 3, 5, and 7 include a tubular body 20 and a decorative layer formed by ink-jet printing on a particular region in a surface of the tubular body in a circumferential direction. The decorative layer includes a plurality of coloured layers 32A, 32B, 32C, and 32D formed in a circumferential arrangement, and wherein each of the coloured layers includes overlap portions 40 where the coloured layer overlaps with neighbouring coloured layers at border areas thereof. The layers are formed by forming a first coloured layer and subsequently rotating the tubular structure by a predetermined angle before forming a second coloured layer. The angle of rotation is chosen such that the first and second coloured layers overlap. The decorative layer as a whole can form a graduated or lattice pattern and maybe formed on a fishing rod or the like.

Description

technical field [0001] The present invention relates to a tubular body with a decorative layer on its surface and a method for forming the decorative layer on the tubular body. Background technique [0002] Various decorations are applied to various products commonly found in the market. Such decoration is sometimes accomplished by printing a decorative layer on the surface of the product, for example by inkjet. For example, among fishing rods, one of the common products on the market, there are fishing rods with a decorative layer applied to the surface by inkjet printing, so as to be able to adapt to various preferences of users, or to stimulate purchase enthusiasm (for example, refer to Patent Document 1 and Patent Document 2). In addition, many techniques for decorating tubular products other than fishing rods by inkjet have been proposed (for example, refer to Patent Document 3).

AI Technical Summary

Problems solved by technology

[0008] In addition, especially when inkjet printing is carried out in the circumferential direction of the pole in several stages, the above-mentioned phenomenon will cause the circumferential boundaries between the decorative layers printed in each stage (the parts where the ink concentration of the decorative layer in each stage is adjacent to each other) area) to produce stripes with light ink density (seams formed by uneven ink density on a part of the circumference of the rod), which impairs the decorative appearance

Furthermore, especially in the case of a product such as a fishing rod in which a long tubular body is frequently subjected to bending force, the above-mentioned circumferential stripes (seams) may cause peeling and damage of the decorative layer.
