Abstract: It is an object of the present invention to obtain in an inexpensive manner a case that allows adjacent cases to be connected to each other, and to provide an article accommodating case that can easily be recycled. In order to achieve this object, an article accommodating case 1 having the shape of a rectangular solid that has an opening 2 at the top is formed, this article accommodating case being characterized in that flanges 3 that protrude outward are formed on the outside surfaces of the opening edges of the respective side walls 1a, 1a, 1a, 1a, and the respective coupling elements of dovetail projections 4a and dovetail grooves 4b of dovetail coupling means 4 are formed in the flanges 3 of the side walls 1a, 1a that face each other.
