Abstract
A vial cap of plastic having a skirt portion press fit onto the neck of a vial. A transversely extending wall having a central opening is integral with the upper end portion of the skirt, and a sealing disc is positioned between the open end of the vial and the transverse wall. A plastic lid having a plastic hinge integrally connected between the lid and the skirt is provided for closing the central opening of the cap during storage. By the construction and arrangement of the plastic vial cap, the fear of aluminum toxicity is overcome and the lid prevents the accumulation of dust and other debris on the sealing disc while the vial is in storage.
