Abstract
A container for granular substances, having a mouth which opens diagonally and upwardly into a triangular shape at an upper part of a left side board. The mouth comprises a pasting piece, which is slightly higher than a front board and a rear board and a sliding board, consisting of an arcuate part and a flap piece contiguous to the circumference of the arcuate part. The sliding board is supported and slides between the inner surface of the front board and the outer surface of a tongue piece formed at the front board. The circumferential edge of the arcuate part always projects above a ceiling board, whether the mouth is opened or closed. The container ensures perfect sealing of granular substances contained therein while the mouth is closed.
