Problems solved by technology

However, if the edge of the packaging film is protruded from the front wall of the box, when the cutting blade is rotated to the cutting position of the packaging film, the moving blade tip will abut against the protruding packaging film portion, and the above-mentioned blade scrape may occur. question

Abstract

A wrap film cutting device having an improved flap is provided to remove a blade trace from the cut wrap film. A wrap film cutting device comprises: a main body of box which includes a front wall(121), a rear wall(122), a bottom wall(124), two marginal walls facing each other, and an open hole of the box, and an adhesive layer, and a flap(50) to make a wrap film marginal end separated from the front wall of the box; and a cover of a box which includes a front wall of the cover(24), a cut blade(22) fixed on the front wall of the cover, a V-shaped blade end and an upper wall(21). A size of the flap(H) satisfies a following equation: S x cosR = A x sinR + H x cosX, and H x sinX <= (A x corR + S x sinR) - B.

Description

technical field [0001] The present invention relates to a wrapping film device that accommodates a roll of wrapping film used for packaging food and other articles in a container and can easily pull the wrapping film out of the container. More specifically, the present invention provides a packaging film device that does not cause the phenomenon called "knife edge rubbing" in which the cutting blade touches the packaging film pulled out from the container and damages the packaging film. And the packaging film and its edge (cutting edge) can be separated from the container wall by the flap, so that the packaging film can be pulled out of the container by pinching the edge of the packaging film with fingers. Background technique [0002] In the past, it is known to store the packaging film roll used for packaging food or other articles in the container, when the packaging film is used, a predetermined amount of packaging film is pulled out of the container by hand, and the pac...
