Document Type and Number:
WIPO Patent Application WO/2023/226968
Kind Code:
A1
Abstract:
A composite sheet for packaging, a sleeve for packaging, and a container and a manufacturing method therefor. The composite sheet comprises main fold lines (100), which extend in a first direction (D1) and divide the composite sheet into a main region (200) and peripheral regions (300), wherein the main region (200) is connected to the peripheral regions (300) in a second direction (D2) that intersects the first direction (D1). The peripheral regions (300) each comprise first fold pattern regions (310), which each comprise: a first fold line (101) and a second fold line (102), which extend in the second direction (D2) and are spaced apart from each other in the first direction (D1); a first auxiliary fold line (101A), which is located at the side of the first fold line (101) facing the second fold line (102) and at least partially extends in the second direction (D2); and a second auxiliary fold line (102A), which is located at the side of the second fold line (102) away from the first fold line (101) and at least partially extends in the second direction (D2). In the first direction (D1), the maximum distance between the first fold line (101) and the first auxiliary fold line (101A) and the maximum distance between the second fold line (102) and the second auxiliary fold line (102A) are respectively less than or equal to 20% of the distance between the first fold line (101) and the second fold line (102).
