Title:
COVER MEMBER PROVIDED WITH LIQUID DISCHARGE HOLES
Document Type and Number:
WIPO Patent Application WO/2012/008064
Kind Code:
A1
Abstract:
A second pull tab (4) for liquid discharge is provided on a cover body (2) of a cover material. A first half cut (10) is formed in a bottom sheet (5) so as to cut across the base part of the second pull tab and so as to connect two points (10a, 10b) on the outer edge of the bottom sheet (5). A subregion extending from the first half cut inwards toward the surface of the cover body is formed as a peeling region to be peeled at the time of liquid discharge. Multiple half cuts (12) for discharge holes are formed in the bottom sheet in said subregion. When the second pull tab is peeled off, the top sheet peels off and is separated from the bottom sheet (6) in the direction from the first half cut area towards the prescribed subregion. At this time, the discharge hole half-cut areas are removed along with the top sheet, creating discharge holes (12A). A second half cut (9) may optionally be made from the aforementioned two points (10a, 10b), or from two points (11a, 11b) which are defined by shifting the first two points (10a, 10b) on the outside edge of the top sheet in the direction away from the second pull tab.
