Abstract: A package of rolled photosensitive mateiral comprising a core, a photosensitive strip material wound around the core, a light-shielding leader connected to the end of the photosensitive strip material to shield the peripheral surface of the photosensitive strip material from light and side light-shielding covers connected to both sides of the light-shielding leader so that the boundary between the side light-shielding covers and the light-shielding leader corresponds to the boundary between the peripheral surface and the side surface of the photosensitive strip material. The core is formed by laminating at least 2 sheets of a base paper being moistureproof.

Abstract: A core sample box for diamond drilled core samples is integrally molded from a plastics material to form an inner core engaging layer and an outer layer adjacent thereto but separated therefrom. The inner layer defines a plurality of part cylindrical receptacles for receiving the cylindrical cores. The outer layer is spaced from the outer surface of the core engaging layer so that the two layers together forms sufficient rigidity to hold the device against twisting. Further rigidity is provided by connection points between the outer layer and the base of the receptacles molded into the outer layer.
