Abstract: An apparatus is disclosed, the apparatus including a primary storage cavity and an expandable and collapsible secondary storage cavity. The secondary cavity may be selectively attachable, and/or may include one or more rigid reinforcing structures contained within the secondary storage cavity. In some embodiments, the apparatus is a handbag, purse, tote, or clutch. In some examples, the apparatus includes a secondary storage cavity defining a first volume when a secondary access mechanism is closed, and a pliable material that is at least partially contained above an inversion boundary, and where the secondary cavity defines a larger, second volume when the secondary access mechanism is open, and the pliable material is at least partially below the inversion boundary. In certain examples, the apparatus includes a primary and secondary container with connection components configured to releasably attach the containers when they are aligned and brought into close proximity to each other.

Abstract: An apparatus is disclosed, the apparatus including a primary storage cavity, an expandable and collapsible secondary storage cavity, and at least one pair of rigid reinforcing structures contained within the secondary storage cavity. In some embodiments, the apparatus is a handbag, purse, tote, or clutch. In addition, a handbag is disclosed, the handbag including a primary storage cavity, an expandable and collapsible secondary storage cavity, at least one pair of rigid reinforcing structures contained within the secondary storage cavity, and a fastening mechanism configured to fasten the materials defining the secondary storage cavity in a collapsed position.
