PAPER CONTAINER

WIPO Patent Application WO/2020/196127

A1

In order to obtain a paper container that achieves safety by smoothing the corners of a bottom-part seal part to prevent damage to the hands of a person or to other paper containers, and that also improves the design properties of the paper container, the present invention provides a paper container in which a bottom part 9 is formed from first and second outside bottom-surface panels 12, 13 and first and second inside bottom-surface panels 16, 17 that are connected to a trunk-part front-surface panel 5, trunk-part left- and right-side-surface panels 6, 7, and a trunk-part rear-surface panel 8, wherein: the second outside bottom-surface panel 13 is formed so that the distal-end-direction length thereof is greater than that of the first and second inside bottom-surface panels 16, 17 and the first outside bottom-surface panel 12; cutout parts 24 are formed at both distal-end sides of the second outside bottom-surface panel 13, the cutout parts 24 being cut out from cutout lines 23 composed of inclined lines 23a that are inclined relative to the distal-end direction and are linked to distal-end sides 16a, 17a of the first and second inside bottom-surface panels 16, 17 and substantially straight lines 23b that are linked to a distal-end side 13a of the second bottom-surface panel 13 from the distal end of the inclined line 23a; and a projecting edge part 25 is formed at a central portion of the distal end of the second outside bottom-surface panel 13 by the cutout parts 24.
