A polyethylene terephthalate container having a hydrogen generator and catalyst disposed or otherwise incorporated in components of the container, including the closure, closure insert, label, label glue, andor any other portions of the final container assembly. Optically tuned to specifically eliminate the non-germicidal wavelength polychromatic emissions from mercury lamps, this unique optical filter approach significantly reduces the cost in manufacturing reliable water purification systems employing ultraviolet light. The method can be operated on an automated robotic system having a modular architecture. The device further includes a stop apparatus projecting into the conveying path of the second printed sheets and gripping the front edges of the second printed sheets, wherein the stop apparatus is adaptable to be shut off when the first printed sheets are conveyed past.
