Winding body accommodating box and accommodating box containing winding body

Abstract

The invention provides a winding body accommodating box preventing long objects from being damaged and an accommodating box containing a winding body. The winding body accommodating box comprises a body part accommodating a winding body having a long object wound thereon; and a cover part covering the opening face of the body part. When the front panel of the body part is covered by the cover part, a clamping part for clamping the long object is formed on the covered area. The covered area is divided into a main area with three areas and a central area. The area of the clamping part surrounded by an outer edge with a gap is defined as the first area which is larger than the second area and the third area. The maximum height of the clamping part in the first area is more than a half of the maximum height of the first area itself. When the width central part is held to draw out the long object and the long object is disengaged with the clamping part, the clamping force on the end part where the component force along the length direction has increased tension becomes smaller. Therefore, the long object can be prevented from being damaged.

Description

technical field [0001] The present invention relates to a winding body storage case and a winding body storage case, and particularly to a winding body storage case and a winding body storage case capable of suppressing damage to a long object pulled out from the winding body. box. Background technique [0002] Food wrapping film (preservation film) is widely used to wrap ingredients and / or dishes, or tableware such as plates for each dish. Packaging film for food. Typically, a long plastic film (rolled body) wound into a roll is stored in a long rectangular parallelepiped container (storage box), and the film at the front end is pulled out from the roll when used. The required amount is cut off with a cutting blade mounted on the lid of the container. In one product, in order to prevent the cut end of the pulled out film from being rolled back into the container, a temporary fixing portion for locking the cut film is provided on the outer upper portion of the front surfac...

Problems solved by technology

[0005] However, in the storage box of the packaging film described in the above-mentioned Patent Document 1, the length of the notch in the longitudinal center of the tape body is longer than the length of the notches in the longitudinal ends of the tape body, so when the temporary fixing part is formed When the temporarily fixed film is peeled off from the front plate, if the center of the width of the film is pinched and peeled off, the component force in the longitudinal direction of the tension acting on the part of the film that is locked to the two protrusions with strong adhesion increase, the membrane may rupture
