Document Type and Number:
Japanese Patent JP7364332
Kind Code:
B2
Abstract:
Provided is a food packaging container in the form of a plastic molded product and in which a hole can be made. The container is provided with a container body having an opening at the top and a lid body for covering the opening of the container body. The lid body is provided with a flat section (30) formed to a thickness t1 of 150 µm or thicker and a hole-making half-cut part (320) formed on the flat section (30). The thickness t2 of the half-cut part (320) satisfies a condition of (1 µm ≤ thickness t2 of half-cut part 320 ≤ 50 µm). The half-cut part (320) is formed by advancing a high-precision cutting blade formed on a slide into a sheet material while performing parallelism control by independently driving three or more shafts supporting a slide of a press machine.
