Abstract: A carrying case or portable pack is constructed in the form of an attache case. A tray storage area providing receptacles for separately holding relatively long and narrow objects is releasably attachable to the inner surface of the lid and flat bulk storage is provided between the base of the tray and said inner surface. A holding material is attached along the inner side walls of the base and individual pockets, for separate package storage, have a surface material mounted on the exterior thereof which permits releasable attachment to said holding material. The pouches or pockets may vary in size, thus permitting flexibility in storing the packaged materials. In addition, the pouches may be coded, as by color coding, for rapid identification and selection of items to be used for a particular function, for example in a medical procedure.
