innermost layer (11) and an adjacent layer (12) contacting the innermost layer (11), a recessed portion (8) and a flange (2) and (b) a lid member (3) melt sealed (6) to the innermost layer (11) of the multilayer container body (1) at the flange (2), where the innermost layer (11) and the adjacent layer (12) are peelable from each other and having between them a peel strength smaller than the peel strength between the lid member (3) and the innermost layer (11). The flange (2) has two circular notches (4, 5) made in the innermost layer (11), and the multilayer container body (1) and the lid member (3) are melt sealed between the two circular notches (4, 5), with the proviso that a portion (7) of the melt sealed area (6) projects outwardly from the outer circular notch (5), and a depression (13) is made in the innermost layer (11) at the outermost edge of the projecting portion (7) of the melt sealed area (6) by pressing the innermost layer (11) through the lid member (3). Opening is performed by the peeling off the innermost layer (11) together with the lid member (3) from the adjacent layer of the multilayer container body between the two circular notch and begins easily by breaking the innermost layer (11) at the depression (13) at the outermost edge of the projecting portion (7) of the melt sealed area (6). <IMAGE> <IMAGE> |
