Abstract (en)
[origin: EP3266603A1] The present invention pertains to the following: a manufacturing method and a manufacturing device for a paper cup in which a pair of embossing rolls form opposing embossments in a middle section of the paper cup or an outer sleeve which is wrapped around the outer circumference of the middle section; and the improvement of the paper cup. [Solution] Each of dies formed on the surface of a pair of embossing rolls has substantially an identical shape and is provided with the following: a frame section that is formed of a flat surface and that partitions cells which are surrounded by lattice frames extending at regular intervals in the horizontal and vertical directions and mutually crossing; and a projection section that includes four lateral-wall surfaces that raise up from the four directions of the sides of a cell towards the center of the cell, and a peak section formed in a plane or linear shape by assembled distal ends of the lateral-wall surfaces. A pair of the dies are characterized in that: the projection sections of the dies are disposed in a direction of approaching a blank; the vertical and horizontal lengths of a quadrangular shape of a unit section are each set as one pitch, the unit section including a cell, frame sections of two sides respectively extending along the adjacent vertical and horizontal side of the cell, and an intersection of these two frame sections; and one die of the pair is offset by half the pitch in the horizontal and vertical directions with respect to the other die.
