PURPOSE:To prevent the successive release of an adhesive part to firmly connect a tab and a lid main body, by connecting at tab main body part and the adhesive part by a leg part and extending the adhesive surface along both sides of the leg part. CONSTITUTION:A tab 114 is equipped with a tab main body, an adhesive part 128 and the leg part 130 connecting the tab main body part and the adhesive part 128. The adhesive part 128 is connected to the leg part 130 by a connection edge 123 and has the adhesive surface 134 extending to the right of the connection edge 132 and two adhesive surfaces 136 extending to the left of said connection edge 132. That is, the adhesive part 128 has adhesive surfaces on both sides of the connection edge 132 with the leg part 130. Therefore, even when the tab main body part is pulled upwardly or in a right diagnolly upward direction at the time of score breaking or tearing operation, it is prevented that the adhesive part 128 is successively released from the connection edge 132 with a lid main body part and, since shearing force acts on the adhesive part of the adhesive part 128 and the lid main body part, the bonding force thereof is high. |
