<p>PROBLEM TO BE SOLVED: To reliably prevent contents such as books from falling down or moving by forming a groove of a predetermined width in a lengthwise direction of an internal bottom of a storage container and by engaging a stopper with an approximately L-shaped cross section with teeth comprising serrations at predetermined pitches formed on the internal bottom to make them stand detachably. SOLUTION: A groove 6 is formed at an approximate widthwise center of the storage container 1 with a predetermined width across an entire lengthwise direction on an internal bottom 2 of the storage container 1 with an upper face open, and teeth 3 comprising serrations of predetermined pitches are integrally formed like a belt on an internal bottom of the groove 6. A stopper 5 of a predetermined width having an approximately L-shaped cross section formed with teeth 4 to be engaged with the teeth 3 on a lower face of a contact part 5a is provided, wherein when the teeth 3 are engaged with the teeth 4, an upper face of the contact part 5a is leveled with an upper face of the internal bottom 2 to enable the stopper 5 to be supported in a standing state. Thus the stopper 5 serves as bookends on a book shelf, wherein stored books 8 can be prevented from falling down and shifting even if the storage container 1 rocks.</p> |
