<p>PROBLEM TO BE SOLVED: To reduce a weight of a synthetic resin container and improve washing efficiency. SOLUTION: The synthetic resin container 10 comprises a lower frame 11 having a rectangular base and a base grid 14 formed of circular rods in a grid inside the lower frame 11. A sidewall comprises an upper frame 13, circular- rod-formed longitudinal rods 20 for connecting the upper and lower frames 11 and 13 with each other at a predetermined interval and lateral rods 21 formed to intersect with the longitudinal rods 20. The lateral rods 21 have an internal surface formed to be flat in the direction of removing a mold. Gaps can be enlarged, whereby a container received inside can be easily washed. Since the circular rod grid can be formed on the sidewall, the weight can be reduced while securing a strength.</p> |
