Abstract

The invention provides a cutting-off edge and a thin film roll container. Cutting-off performance of the cutting-off edge arranged on the thin film roll container is completely realized, and the safety is ensured so that a user won't be hurted. The cutting-off edge (50) is configured into a long strip along a length direction of the thin film roll container (1) and is used for cutting off a thin film (F) drawn from a thin film roll (R) of the thin film roll container. The central part of the cutting-off edge (50) has bulges (60) in the length direction, the bulges protruding in a direction facing the drawn thin film (F). The bulges (60) have approximately trapezoid shapes, which have flat linear parts (70) at the end sides. The length (L1) of each linear part (70) is more than 1% and less than 5% of the length of the cutting-off edge (50) in the length direction. Variable angles at the two ends of each linear part (70) are less than 7 degrees.

Description

technical field [0001] In particular, the present invention relates to a cutting blade and a film roll storage container. The cutting blade is provided on a film roll storage container for storing a film roll for cutting a film pulled out from the film roll. The film roll is a rolled food product. Plastic wrap, aluminum foil, parchment paper, etc. (hereinafter referred to as "film") for packaging. Background technique [0002] Usually, a film is wound around a paper core to constitute a film roll, and the film roll is housed in a paper-made cuboid film roll storage container. The film roll storage container generally has: a storage part, the upper surface of which is opened, and accommodates the film roll; The film cut off from the roll is pulled out. The cutting edge is usually formed in an elongated shape along the longitudinal direction of the cover. [0003] Since the above-mentioned film is cut and used by the user every time, the cutting edge of the film roll storag...
