<p>A sheet container which can be simply and easily assembled by making use of sheet material characteristics such as flexibility, elasticity, resiliency and bendability, provides a simple and novel form, and can simply meet requirements of space-saving storing after use and re-assembling, wherein a flexible sheet body is divided into first, second and third sheet surfaces, joining flaps as binding margins are allowed to extend from the third sheet surface, respective sheet surface and the joining flaps are bent and joined together to form a triangle-tube-form body trunk. Three pieces of lid flaps extending from the base ends of respective sheet surfaces of the body trunk are sequentially bent from the arcuate fold lines formed at the base ends toward the inside of the body trunk, and one edge end of the lastly-bent lid flap is allowed to go into the inside of the other edge end of the firstly-bent lid flap to mutually let engage engaging recesses provided in respective lid flaps for locking and to bend by warping respective lid flaps for closing.</p> |
