Abstract
The invention provides a container for waste materia, particularly but not exclusively for paper waste, comprising, a casing forming a container for waste material having structure defining an opening for entry to the container, a lid movably mounted on the casing adjacent the opening for movement between an open position allowing waste to be put into the container opening, and a closed position closing the opening of the container, the lid being formed so that in its closed position it extends into the container beyond the extremity of said container structure to occupy a volume within the container at least equal to that of an item of waste for which the container is intended, and means for releasably retaining the lid in its closed position, whereby each time waste is inserted through the opening and the lid closed, the waste in the container is progressively compressed and a space is created for the reception of further waste when the lid is next opened.
