Abstract
A pulp molding negative angle container comprises a conical pulp container which is open on the upper end. The inner wall of the open end of the pulp container has a separation space which is inclined downwards and set outwards. A protruding shoulder is provided on the outer wall of the open end of the pulp container, wherein the outer diameter of the protruding shoulder is larger than the inner diameter of the hole on the open end. When two pulp containers are nested over each other, the protruding shoulder is placed on the upper hole of the open end and a separation gap is formed between the separation space on one pulp container and the outer wall on the other pulp container.
