Abstract
A transparent, light resistant container is provided for storage of medicinal agents, such as tablets, capsules, and the like. In broad terms, the container includes a container body having self-sustaining wall structure of predetermined thickness formed from a synthetic resin composition. A quantity of a coloring agent dispersed in the resin composition. The quantity of the coloring agent is correlated with the thickness of the wall structure to permit transmission through the wall structure of no more than 10% of light having a wavelength of between about 400 nm to 450 nm while permitting transmission through the wall structure of adequate visible light to allow external visual inspection of printed characters on solid medicinal tablets and capsules stored in the container. In addition, an amount of a UV absorber is dispersed in the resin composition. The amount of UV absorber is also correlated with the thickness of the wall structure and sufficient to permit transmission through the wall structure of the predetermined thickness of no more than 10% of light having a wavelength between about 290 nm to 400 nm.
