A thermoformed container is formed with a receptacle and a separate cover which is hingeably and detachably attached to the receptacle. The receptacle and cover each have a hinge flange with side skirt walls descending therefrom in which indentations are formed during the thermoforming process. The indentations on one of the cover or receptacle form pivot pins which seat in the sockets defined by the indentations on the other of the cover or the receptacle, defining an axis of rotation about which the cover can rotate with respect to the receptacle. The cover and receptacle can thus can be formed of different plastics or of plastics in which conventional integral living hinges can not be used. The pivot pin indentations are produced in the thermoforming process by forming pins which engage into the softened sheet at the side skirt walls. The plastic material cools and hardens to form sharply defined pivot pins.
