Proposed is a box container suitable for holding and transporting a plural number of sheet-like bodies such as lead frames for semiconductor devices such as ICs. The box container consists of three parts including (a) an inner box member to hold the sheet bodies, (b) a box tray member into which the inner box member is inserted and (c) a covering member to be engaged with the box tray member. The inner box member is an integral plastic body consisting of a generally rectangular base plate and side plates each connected, independently from the others, at the bottom line to one of the four sides of the base plate while each of the side plates is jointed to the base plate not perpendicularly but with outward inclination from the bottom to the upper periphery in such a resiliently bendable fashion that, when the inner box member is inserted into the box tray member, each side plate is contacted with the side wall of the box tray member with resilience to take a perpendicular disposition to ensure little play between the side plates and the sheet bodies therein while good working efficiency is ensured in putting and taking sheet bodies into and out of the inner box member.
