Infusion bag

Abstract

An infusion bag is provided and has a drawstring that is doubled through an opening in an upper portion of a bag to form a loop. One portion of the drawstring extends from the loop and around the bag and back through the loop, with another portion of the drawstring proceeding from such loop. These two portions form pull members for squeezing the bag. The drawstring can also extend around the bag in a doubled state. In addition to extending through the bag opening, the doubled drawstring can also extend through a looped end thereof.
