<p>PURPOSE:To make the dimension of a shaking-out port constant and further make it possible to surely close the port. CONSTITUTION:A triangular section 1a is defined in the upper corner of a front panel 1 near, a left side panel 2 by a broken line, while a triangular section 1a having the same size as the aforementioned section is defined in the upper corner of a rear panel near the left side panel 2 by a broken line, and the left side panel 2 is divided into an upper section 2a and a lower section 2b by an opening whose upper end being a point of intersection of broken lines. A horizontal incision 20 is formed in a left side inner wall 6 at a location crossing a triangular protrusion 19 provided at the lower end of the section 2a. If the section 1a is cut off along the broken line to turn an opening part, a shaking-out port S having a certain size is exposed, so that the contents can be shaken out therefrom. If the protrusion 19 at the end of the opening part is inserted into the incision to close the port S, the opening part is prevented from being opened easily and hence the port S can be closed surely.</p> |
