A container used for selling powders such as a washing powder and the like comprises a main body for filling the powders therein and a lid member for covering an upper opening of the main body. A band member is disposed through a score at a peripheral edge of the lid member except at a part of the peripheral edge thereof and has a peeling-off projection formed at its end. A picking-up projection is disposed at a wall of the lid member just above a space where no band member is defined. Each of these projections has a rectangular shape and has opposite surfaces. The surfaces of the peeling-off and picking-up projection are at approximately right angles to each other. These projections serve to protect one another from impacts or shocks exerted on one another. As the result, these projections are prevented them from deformation. Therefore, the container gives confidence that it can be opened by the impacts or the shocks exerted thereon at ease. After it has been opened, the fact can be confirmed because it cna hardly be opened without peeling off the band member.At least a pair of rivets is preferably formed at upper portions of pillars of a frame member of the main body because the pillars have a mechanical strength enough to hold out against a force exerted through the handle member on the rivets.
