Bag with collapsible pocket

Abstract

A bag includes an interior compartment defined by front, rear, side, bottom, and top panels. A collapsible pocket is disposed in the interior compartment and is defined by a vertical divider, a front wall, a rear wall, and a bottom wall. The vertical divider is disposed between the front and rear panels and is slidable relative to the front and rear panels. The front wall is adjacent an inside surface of the front panel and is attached at opposite ends thereof to the one of the side panels and the vertical divider. The rear wall is adjacent an inside surface of the rear panel and is attached at opposite ends thereof to the side panel and the vertical divider. The collapsible pocket includes an expanded configuration the divider is spaced from the side panel and a collapsed configuration wherein the vertical divider is disposed adjacent the side panel.
