Vulcanized fiber sheet having a serrated cutting edge, a carton having said sheet adhered thereto, and a method of adhesion thereof
InactiveUS6173876B1Increase elasticityImprove rigidityBox making operationsFlat article dispensingMetallic foilFiber
The present invention is a sheet having a serrated cutting edge attached to a carton case containing a roll of a cooking sheet such as a synthetic resin film, paper sheet and metallic foil, the sheet having a serrated cutting edge used for cutting the cooking sheet. The sheet having a serrated cutting edge is made of a vulcanized fiber. A moisture-proof film of a synthetic resin is formed on the two surfaces of a vulcanized fiber blank in order to make the most of the rigidity and elasticity which are advantages of the vulcanized fiber and decreases moisture absorption which is a disadvantage thereof. The invention also is a carton to which the sheet having a serrated cutting edge is adhered to as well as to a method of adhering the sheet having a serrated cutting edge to the carton by utilizing the moisture-proof film and ultrasonic adhesion.

As shown in FIG. 1, a helical flute has a constant lead part and a gradually increased lead part. The constant lead part has an axial length ranging from 0.3xLA to 1.2xLA and includes at least entirety of a leading part, so that the cutting performance of a cutting edge at the leading part and shape of chips (curled shape, etc.) are stable. In the constant lead part, because a lead is the smallest and a helix angle is large, a rake angle of the cutting edge is large, so that an excellent cutting quality is obtained and the chips become curled well. Meanwhile, in the gradually increased lead part, because of the lead gradually increased toward a shank, the chips are rapidly discharged toward the shank. Thus, the excellent cutting performance and the chip discharge performance rendered by the gradually increased lead are highly stabilized by the presence of the constant lead part. In this way, the durability is further improved.
