A package for an infusion bag is disclosed comprising a cavity defined by front and rear opposing surfaces and top and bottom lids. The top lid outwardly biases top edges of the front and rear opposing surfaces for preventing the top edges from brushing against a string during retraction of the infusion bag. A lid is located on the bottom of the cavity, opposing the top lid, where the bottom lid has one free edge, and wherein inwardly biasing side edges of the surfaces outwardly biases the free edge of the bottom lid from the adjacent surface.
