ABSTRACT:
A method is disclosed for making plastic products that enables adjacent portions thereof to be easily folded into juxtaposed relationship. A hinge is formed by utilizing an angled or curved cutting tool to create a continuous slit which in a preferred configuration (when viewed in profile) is generally L-shaped so that it extends from one surface of the product to a first location that is within the products' body and then extends therein from the first location to a second location also within the thickness of the body. The slit opens onto the one surface and thereby forms a flexible bridge integral with those portions of the product adjacent thereto, the bridge permitting such adjacent portions to be flexibly folded into juxtaposed relationship.
