Abstract

See full text

A pulp molding container includes a conical pulp container open at an upper end. An inner wall of the open end of the pulp container has a separation space defined therein which is inclined downwards and set outwards. A protruding shoulder is defined on an 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 of the upper container rests on the upper hole of the open end of the lower container, and a separation gap is formed between the separation space of the lower pulp container and an outer wall on the upper pulp container.
