Abstract
To provide an air passage for torch combustion in the torch main body to ensure the freedom of design. A decorative elongated object according to the present invention includes an elongated material (100) with a cross section having a plurality of radial lines (L2) and being uniform from one end (1a) to another end (1b), a cavity being formed at the center of the elongated material, in which the elongated material has a side surface at least partially tapered to be thinner toward the other end (1b) from the one end (1a), with the radial lines (L2) partially cut and removed along a side surface cutting plane intersecting with the side surface.
Claims13
A decorative elongated object comprising an elongated material with a cross section having a plurality of radial lines extending from an inner side toward an outer side, and being uniform from one end to another end, wherein the elongated material has a side surface at least partially tapered to be thinner toward the other end from the one end, with the radial lines partially cut and removed along a side surface cutting plane intersecting with the side surface, and the one end has an end surface being angled toward a space of the end surface.
A method for manufacturing a decorative elongated object that is at least partially tapered, the method comprising:
- molding, by extrusion molding, an elongated material having a cross section having a plurality of radial lines extending from an inner side toward an outer side;
- cutting and removing a side surface of the elongated material, the cutting being performed in an angled direction with respect to the side surface;
- and cutting and removing an end surface at one end of the elongated material in an angled direction toward a space of the end surface.
