Claims (1)

[Scope of utility model registration request] Two layers of inner and outer walls are coated with a film of strip-shaped base paper and face each other with one surface facing the outside and the other surface is inside, and an inner surface is attached to the outer edge of the inner wall that is continuous with the outer wall. an annular frame in which one longitudinal end of a closed cross-sectional base having a bent piece attached thereto is inserted and coupled between the inner and outer walls of the other end, and the inner wall along the bent end surface of the annular frame; A slit with discontinuous portions interposed therebetween is formed around the entire circumference of the section, and the peripheral edge of the bottom plate is removably fitted into the slit, and the lower surface near the inner circumference of the peripheral edge is connected to the bent piece. What is claimed is: 1. A food container that is supported by an end surface and has a notch formed in a peripheral portion of the bottom plate that bypasses and corresponds to a discontinuous portion of the slit.
