Abstract:
1. An infusion bag for manually filling and closing the bag, comprising: an infusion bag defined by front and rear opposing surfaces, top and bottom opposing ends, and first and second opposing side edges joining the front and rear surfaces wherein said top end is open forming a mouth through which material can be placed in the bag, wherein said bag is substantially rectangular having top corners and a top edge at the top end, and a pair of adjacent apertures located in said rear opposing surface adjacent the top edge thereof, midway between said side edges; first and second loops, said first and second loops being disposed respectively, on the respective top corners of said rear surface of said bag, and a third loop being disposed on said front surface of said bag midway between said first and second opposing side edges, and a string having first and second ends, wherein a single strand of said string passes continuously through said first loop, both apertures, and said second loop on the rear surface of said bag and then portions of the single strand loop around each opposing side edge onto the front surface of the bag and coming together down through the third loop in a double strand and ending below the third loop in two free ends; each of said apertures and said loops being present in association with a reinforcing element; said apertures and loops being positioned in said bag, and said string being movable through said apertures and said loops such that when said free ends of said string are pulled downwardly, a first pair of diagonal fold lines in said front and rear opposing surfaces defined by said reinforcement elements permit the top corners of said bag to fold down, and a third fold line parallel to a top edge of said bag and defined by said reinforcing elements permit a second fold of said bag when said string is pulled further, causing said first and second loops to be pulled adjacent said third loop, resulting in cinching of the folded top corners and completely closing the mouth of the bag.
