Abstract

PURPOSE: To make an inverted-pyramid-shaped bottom plate having slopes convergent to a drain port, easily and cheaply even if the bottom plate is large, by pressing a thin sheet along a plurality of lines intersecting one another on the drain port.
CONSTITUTION: The drain port 11 is made in the center of the thin sheet 10 first. The sheet is sequentially pressed along the diagonals 12, 13 of an oblong defined by lines 14W17. The thin sheet 10 is sequentially bent upward along the lines 14W17. The adjacent edges of planes 18W21 are coupled to each other, thereby making the inverted-pyramid-shaped bottom plate having four slopes convergent to the drain port 14. According to this invention, it is needless to use an upper and a lower dies as in conventional cases, the production cost is reduced, and even a large bottom plate can be easily manufactured. Such a bottom plate is used for the bottom of a freezing or cooling showcase etc.
