    Abstract: A method and apparatus for sterilizing packaging through irradiation with an excimer ultraviolet lamp which may be integrated on a packaging machine. The excimer ultraviolet lamp emits radiation at a substantially monochromatic wavelength within the ultraviolet band of the electromagnetic spectrum. The excimer ultraviolet lamp is composed of a quartz shell containing one of the following gaseous compounds: Ar.sub.2, Kr.sub.2, Xe.sub.2, ArCl, KrCl, KrF or XeCl. The KrCl gas excimer ultraviolet lamp which generates a wavelength of 222 nanometers is of particular interest for the present invention. In one embodiment, the lamp has a central aperture for flowing through a cooling fluid to remove heat from the lamp. If the excimer ultraviolet lamp is integrated on a form, fill and seal machine, the cooling fluid may be the desired contents filled into a container fabricated on the form, fill and seal machine. The materials sterilized by the present invention are fabricated into many different containers such as flexible pouches, stand-up pouches, parallelpiped containers and gable top cartons. The material may be subjected to a sterilant prior to irradiation by the excimer ultraviolet lamp. The sterilant may be hydrogen peroxide, peracid, ozone or the like. The concentration of the sterilant may have a range of between 1% to 55%.

    Abstract translation: 一种通过用准分子紫外灯照射来包装的方法和装置,该准分子紫外灯可以集成在包装机上。 准分子紫外线灯在电磁波谱的紫外波段内以基本单色的波长发射辐射。 准分子紫外灯由含有以下气体化合物之一的石英壳组成:Ar2,Kr2,Xe2,ArCl,KrCl,KrF或XeCl。 产生波长为222纳米的KrCl气体准分子紫外线灯对于本发明是特别感兴趣的。 在一个实施例中,灯具有用于流过冷却流体以去除灯的热量的中心孔。 如果将准分子紫外线灯集成在一个表格上,填充和密封机器,那么冷却液可以是填充到形成,填充和密封机器上的容器中的所需内容物。 将本发明灭菌的材料制成许多不同的容器,例如柔性袋,立式袋,平行的容器和山形顶部纸箱。 该材料可以在被准分子紫外线灯照射之前经受灭菌剂。 灭菌剂可以是过氧化氢,过酸,臭氧等。 灭菌剂的浓度可以在1%至55%之间的范围内。
