Abstract
A small needle tip cover is provided which is capable of rendering a used disposable needle safe from accidental punctures. The needle tip cover can take the form of a small rectangular piece of sheet metal that is bent back upon itself. The bend is shaped to provide a spring means which is operable to force the opposing sides of the cover together. The inner surfce of each side includes a plurality of serrated burrs which contact the shaft of a used needle and prevent the tip thereof from escaping. The needle tip cover is kept open by a collapsible column. Until the introduction of a used needle tip therebetween, the column is subject to failure from any slight transverse force, such as that provided by the shaft of the needle pressing there against.
