Abstract

Deep-drawn tin plate container has a cross-section designed to assist removal of the container from the forming tool. The container has a base (3) of uniform thickness connected by a circular arc section (4) to a section (5) where the metal thickness decreases rapidly. Above this is the main wall of the container (6). This part of the container is of conical shape. Round the top of the container is a thicker rim (2) connected to the side by a tapering section (7). The material of the rim is softer than the rest of the container, and is used as a lug for the removal devices (C) to press against. The container, which has a smooth inner surface, is formed using a conically shaped deep drawing tool.
