The present invention provides a method of producing improved infant care articles characterized by the inclusion of a non-toxic, non-irritating phosphorescent material with the material of construction of components of the infant care articles so that such components phosphorescently emit light visible in a darkened environment, allowing the location and position of the articles to be readily determined without the need for an additional light source. Embodiments of infant care articles produced in accordance with the invention, including infant pacifiers, bottle assemblies, and clothing, are disclosed.

A process for producing infant care articles having one or more components formed of a plastic material by molding or extrusion, so that at least one of such components has the property of phosphorescent emission of light radiation visible to the human eye in a darkened environment, comprising the steps of selecting a non-toxic, non-irritating phosphorescent pigment material for addition to the plastic material from which one or more components of the infant care article is to be formed, such phosphorescent pigment material having a thermal decomposition point above the melting point of the plastic material and not being subject to chemical degradation by the plastic material; then mixing a predetermined quantity of said phosphorescent pigment material with a predetermined quantity of said plastic material in a ratio selected to provide the desired intensity of phosphorescently emitted light; then forming one or more components of the infant care article to be produced from said plastic material containing said phosphorescent pigment material by molding or extrusion; then forming a transparent coating, of a non-toxic nonphosphorescent material, on the surface of said one or more components of the infant care article produced from said plastic material containing said phosphorescent pigment material, so as to provide a barrier between the phosphorescent pigment material and the user of the infant care article and prevent direct contact with said phosphorescent pigment material; forming any remaining components of the infant care article to be produced; and then assembling all components of the infant care article to produce the finished article with one or more components having the property of phosphorescent emission of visible light.
