PROBLEM TO BE SOLVED: To provide a built-up container capable of building up or folding side plates by an extremely simple operation such as a one-touch operation by a simple constitution. SOLUTION: Coupling pins 430 are provided on both upper sides of a second side plate 420, and a one-touch retainer 450 for engaging the coupling pins 430 with each other is provided on an outer surface of a side frame 412 of a first side plate 410 opposing the same. The one-touch retainer 450 has a pot-bellied pin therein to engage/disengage the coupling pin 430 by the elastic deformation thereof. As a result, when the second side plate 420 is firmly pressed against the side frame 412 of the first side plate 410, the coupling pin 430 is engaged with the one-touch retainer 450. When the second side plate is firmly detached, the second side plate 420 is decoupled from the first side plate 410 to enable the build-up in one action. COPYRIGHT: (C)2009,JPO&INPIT
