Title: Case for wrap film roll
Inventor: KAI HISAO
IPC: B65D83/08
Filed: 1988-04-15
Abstract: PURPOSE:To improve the cutting sharpness and durability of a wrap film cutting edge, by impregnating a film case with a resin solution or resin latex from its cut face and making the cut face impregnated with the resin at a high con centration to be used as the film cutting edge. CONSTITUTION:For use as case reinforcement, two-pack type resin such as polyurethane resin, phenol resin or thermosetting resin, or one-pack type resin such as polyvinylidene chloride resin is employed. The reinforcement is effected by coating and impregnating the cut face of a film case paper with said resin by a brush or roller. Since said paper is not compressed horizontal-wise, fine pores exist there in a capillary form and with communication with one another, thereby permitting a deep penetration of a large amount of the resin thereinto. The upper edge of a front face 1 is cut and formed into saw-toothed shape. Since this saw-toothed part 7 has an exposed cut face, a viscous resin can be easily penetrated thereinto. Therefore, the paper is hardened with the resin, resulting in improved warp film cutting effect and, even if the application of depressing force upon the case edge is repeated upon film cutting, there is no lowering in the paper tension.
