A unitary shielded snap type hinge closure including a cap body portion adapted to be secured to a container having a dispending opening therein. The cap body portion includes a top portion raised above a shoulder and a periphery therearound and includes a mating portion. A lid is hinged to the cap body by a solid one-piece unitary hinge member integrally formed between the cap body and the lid, the hinge member being attached on one side directly to the lid and on an opposite side to the cap body by a film hinge and including a central planar portion. The hinge member includes a side shoulder depending from either side of the central planar portion of the hinge member when the lid is in its opened position and being attached on one end directly to the lid and on an opposite end to the cap body by said film hinge so that a snap is provided in the side shoulders during operation of the hinge member and the side shoulders mate with the mating portion of the cap body in a closed position of the lid to inhibit contamination and reduce seepage around the hinge closure.
