PAPER CONTAINER
Document Type and Number:
WIPO Patent Application WO/2020/059883
Kind Code:
A1
Abstract:
Provided is a paper container 1, wherein: mutually facing surfaces of a first top seal panel 20 and a second top seal panel 22 are adhered to each other to seal a top part 4; a side panel 16 is folded at a first side surface panel folding line 26 and a second side surface panel folding line 27 to form an approximately triangular flap 35; a front surface-side top surface panel vertical folding line 17, a front surface-side top surface panel vertical folding line 18, and a front surface-side top seal vertical folding line 23 are mountain-folded; and a second top part horizontal folding line 15 and a rear surface-side top seal vertical folding line 24 are valley-folded to form a top part 4 by folding the flap 35 onto the left and right side surfaces of a cylindrical body part 3, the width W1 in the left-right direction of a front surface-side top seal panel 20a inside the first top seal panel 20 is formed larger than the width W4 in the left-right direction of the cylindrical body part 3, so that a resistive force with respect the folding of the flap is reduced and bending of the flap is suppressed. Thus, a paper container is obtained in which bulging of the body is suppressed, and which has a pleasing design and does not cause failure during storage and transportation.
