Abstract

PURPOSE:To easily perform opening without the possibility of coming-off of an opening tab, by making the root of the fulcrum part of the opening tab flat so as to have flatness of a specific value or less and bonding the mount part of said tab to the fulcrum part by an adhesive. CONSTITUTION:An opening tab 3 is equipped with a press tearing leading end 13 at one end part thereof and a grip part 14 at the other end part thereof and has a fulcrum part 15 between them. An opening tab mount part 19 independent from the deformation of a panel is provided to the opening part 10 of a lid material 2 in close vicinity to a score 9 through the deformation preventing rib 18 of a peripheral step part. At the fulcrum part (bonding part) 15 of an opening tab 3, the flatness of the root 16 is made smaller than + or -50mum. A fold is formed inside both end parts 24, 24 of a U-shaped break 17 is a form of a step 25 in order to enhance the flatness of the root 16 and this lower fold is set as the root 16.
