A tray portion (21) is constituted by a front receiving panel (1), a bottom surface panel (2), a rear surface panel (3), bottom side panels (6) integrally connected to the respective sides of the bottom surface panel (2), and rear side panels (7) integrally connected to the respective sides of the rear surface panel (3). A lid portion (22) is constituted by a top surface panel (4), a front surface panel (5), top side panels (8) integrally connected to the respective sides of the top surface panel (4), and front side panels (9) integrally connected to the respective sides of the front surface panel (5). The front receiving panel (1), the bottom surface panel (2), the rear surface panel (3), the top surface panel (4), and the front surface panel (5) are integrally connected one to another, and configured to cover products. A cut line (12a) for separating the lid portion (22) from the tray portion (21) is formed so as to pass through only an area of the rear surface panel (3), only an area of the top surface panel (4), or areas of both the rear surface panel (3) and the top surface panel (4). When products are exhibited in the tray portion (21), the lid portion (22) is severed along the cut line (12a), and separated from the tray portion (21).
