An apparatus for filling empty spouted and flexible fluid bags with a fluid substance, said filling apparatus comprising:

• means first including pushing assemblies for advancing at least individual ones of the empty bags towards a filling station;
• means for sterilizing at least a portion of each spout in a sterilizing chamber;
• second means for advancing each spouted bag through said sterilizing means;
• said sterilizing means including means for introducing gaseous hydrogen peroxide into said sterilizing chamber and means for irradiating the spouts in said chamber with preselected ultraviolet radiation;
• and,
• means for filling the empty bags with a fluid substance in a sterile environment;
• said first advancing means includes separating means for separating individual bags from a strip of flexible strips;
• said first advancing means includes track means for guiding spouts of successive bags in response to movement of said pushing assemblies.

A method of filling empty spouted flexible fluid bags with a fluid substance, said method comprising the steps of:

• advancing at least individual ones of the empty bags;
• sterilizing at least a portion of each spout in a sterilizing chamber;
• advancing each spouted bag through the sterilizing chamber;
• said sterilizing step including introducing gaseous hydrogen peroxide into the sterilizing chamber and irradiating the spouts with preselected ultraviolet radiation;
• and
• filling the empty bags with a fluid substance in a sterile environment;
• said advancing steps include providing a pair of intermittently reciprocatable pushing assemblies, each mounted in laterally spaced apart relationship to each other;
• each of said pushing assemblies includes a pivotal spout engaging arm having one position engaged with a spout and a second position removed from the spout;
• each of said pushing assemblies includes means operable for selectively moving said spout engaging arms between said engaged and removed positions;
• each of said arms being oriented at an angle such that they do not interfere with the other said arm along the predetermined feed path when in said removed position and pushing a spout to advance an associated bag when an arm of one pushing assembly is in a spout engaging position while retracting an arm of the other pushing assembly when it is in its removed position.

• further including the step of providing the sterilization chamber with tunnel means for sealingly receiving the cap and spout;
• and
• conveying the cap and spout by conveying means comprising a pair of laterally spaced apart endless conveyor assemblies in combination with the tunnel means to define the sterilization chamber, each of the conveyor assemblies including a plurality of slats horizontally extending therefrom, each of the slats having at least a recess formed thereon so as to form, in combination with recesses of adjacent ones of the slats, a spout engaging arrangement for engaging and advancing each spout.
