Claim:
A backpack comprising: a strap assembly for mounting the backpack to a user, the strap assembly comprising an anchor portion having cord-support surfaces; a body coupled to the strap assembly, the body having a closure portion defining an opening through which an interior region of the body can be accessed selectively, the closure portion having an opened position with end portions extended away from one another thus permitting access to the interior region of the body through the opening, and the closure portion having a closed position with end portions moved toward one another thus inhibiting access to the interior region of the body through the opening; and a cord coupled to the strap assembly and to the end portions of the closure portion of the body, the cord having a first configuration permitting extension of the end portions of the closure portion away from one another and movement of the closure portion to the opened position, the cord also having a second configuration inhibiting extension of the end portions of the closure portion away from one another and maintaining the closure portion in the closed position, wherein the cord is positioned to slide with respect to two pairs of the cord-support surfaces, each pair of the cord-support surfaces being movable with respect to one another from relatively near positions to relatively far positions as the closure portion is moved from the opened position to the closed position, wherein each pair of cord-support surfaces comprises an upper cord-support surface and a lower cord-support surface, wherein the upper cord-support surfaces and lower cord-support surfaces are movable with respect to one another from relatively near positions to relatively far positions as the closure portion is moved from the opened position to the closed position.
