PROBLEM TO BE SOLVED: To make the rear surface section of a housing section hard to crush even when a load is applied to a lid upper surface section by superposing reinforcing pieces which are formed by extending both right and left side surface sections of the housing section respectively, and have a length of a specified ratio or higher of the length of the rear surface section of the housing section, from both sides of the rear surface section of the housing section along the internal surface of the rear surface section. SOLUTION: This container 10 comprises a housing section 12 and a lid section 11. The housing section 12 comprises a front surface section 13, a bottom surface section, and a rear surface section 14 which have a laterally long rectangular shape, and a right side surface section 15a and a left side surface section 15b which have an approx. square shape. Then, by extending both right and left side surface sections 15a and 15b respectively, reinforcing pieces 16a and 16b of which the lengths L1 and L2 are 10% or more of the length of the rear surface section 14, are formed. The reinforcing pieces 16a and 16b are superposed along the internal surface of the rear surface section 14, from both sides of the rear surface section 14. The lengths of the reinforcing pieces 16a and 16b are preferably the same length as the shorter edge or less of the rear surface section 14 of the housing section. By this constitution, since the reinforcing pieces 16a and 16b are superposed on the rear surface section 14 of the housing section, the rear surface section becomes hard to crush.
