PURPOSE: To make the title container visible from outside and to transport the plant received therein without damaging the same, by molding a transparent thermoplastic thin layered plate at a shot and erecting space forming regions wherein right-angled triangular side walls are formed on both sides of said plate.

CONSTITUTION: This container is formed by molding a thermoplastic transparent film at a shot and, after the bottom part of a bowl part A1 is exactly received in the recessed space within a surrounded bottom wall region 1, a pair of space forming regions 2, 3 positioned on both sides of the surrounded bottom wall region 1 are erected on the rib upper surfaces 14a of the surrounded bottom wall region 1 by bending this layered regions 6, 7. By this method, the side walls 20, 30 formed on both sides of the space forming regions 2, 3 are mutually brought into contact with each other and pin-shaped engaging recessed and protruding parts 21A, 21B are respectively engaged with rectangular recessed and protruding parts 22A, 22B and to form the inner space 40 held between the side walls 20, 30 and a lower space 41 fixing the outer periphery of the bowl part A1 is formed to the inner wall surface thereof and a spherical expanding space 42 receiving the plant main body A2 positioned on the bowl part A1 is formed to the upper position thereof and, further, opposed gap recessed parts 23A, 23B function as an air hole and a water injection hole.
