A laser irradiation apparatus includes: multiple irradiation units each to emit a laser beam to a surface of a base to form a pattern, the multiple irradiation units, including: a first irradiation unit to emit a first laser beam; and a second irradiation unit to emit a second laser beam; and a circuitry to: control the first irradiation unit to irradiate only a first irradiation region on a surface of a base with the first laser beam; and control the second irradiation unit to irradiate only a second irradiation region on the surface of the base with the second laser beam. The first irradiation region and the second irradiation region are not overlapping each other.

Laser irradiation apparatus, laser irradiation method, container, and containment body

A method for manufacturing a container product is disclosed. The method includes filling a container with contents; forming information on the container, the information including a number, a letter, and an image, the information being formed by a first pattern, the first pattern being made up of a collection of second patterns; and heating or cooling the container before or after the forming of the information on the container.

Method and system for manufacturing container product

A marking device, a medium, a container, and a marking method. The marking device includes a first marker including a first optical system having a first focal point, the first marker being configured to concentrate a first light onto a first area of a non-planar portion of a medium to perform marking on the first area, the non-planar portion including a plurality of areas including the first area and a second area, and a second marker including a second optical system having a second focal point. The second marker is configured to concentrate a second light onto the second area to perform the marking on the second area, and the second focal point of the second optical system is different from the first focal point of the first optical system in a direction parallel to a central axis of the first optical system.
