Definitions

  • the present invention relates to a pair of roll support members that are used when housing in a packaging material a roll-form recording material comprising a long length of recording material sheet wound around a cylindrical core, and a recording material package in which a roll-form recording material has opposite ends thereof supported by a pair of roll support members and is housed in a packaging material.
  • the recording material sheet when storing and transporting a long length of recording material sheet, the recording material sheet is generally wound into roll form around a cylindrical core, then housed in a pulp-made packaging material such as a corrugated cardboard housing, and stored and transported.
  • the outermost peripheral portion of such a roll-form recording material sheet (hereinafter called a roll-form recording material) is usually covered by a light-shielding sheet so that, when the recording material is a light-sensitive material, it is not exposed to light or damaged, and the opposite ends thereof in the width direction are also protected by light-shielding protecting plates so that it is not exposed to light or damaged from the opposite ends.
  • a roll support member having a protruding portion formed integrally with a flat substrate (a flange having a protruding portion) has been proposed.
  • the roll-form recording material is supported by the flat substrates when housing the roll-form recording material in the packaging material, and it is therefore possible to support the recording material so that it is not in contact with the packaging material.
  • this roll support member is formed using a synthetic resin material as a main component, the flat substrate has the problem that its cushioning properties and mechanical strength are insufficient.
  • the roll-form recording material when the roll-form recording material is stored for a long period of time, in a case in which the recording material is a light-sensitive material, a silver compound, etc. contained in the light-sensitive material reacts with moisture in air, thus degrading the light-sensitive material and causing uneven recording in some cases. Since the outer peripheral portion and the end portion of the light-sensitive material roll are covered by the light-shielding sheet and the protecting plate as described above, moisture in the air hardly penetrates it.
  • a pulp material is widely employed as the core of the light-sensitive material roll, the pulp material being advantageous in terms of strength and cost but having poor moisture resistance, and the hollow portion thereof is usually in contact with the outside air.
  • the light-sensitive material roll when the light-sensitive material roll is stored for a long period of time, not only is it necessary to protect the light-sensitive material roll from physical impact and prevent it from being deformed or damaged, but also it is necessary to prevent the hollow portion of the core from contacting the outside air and moisture penetrating.
  • a roll support member has been proposed that is formed from a highly moisture-resistant synthetic resin, can be inserted (fitted) into a core, and is used in combination with a cushioning member formed from a low density material, that is, a recording material package (recording material) in which a roll-form recording material core and a roll support member therefor are united with a cushioning member therebetween and housed in a packaging material. Since the roll-form recording material core is thus blocked by the highly moisture-resistant roll support members inserted (fitted) thereinto, the hollow portion of the core is not in contact with the outside air. Moreover, even when the recording material package is exposed to a physical impact such as being dropped, since the cushioning member, which is formed from a low density material, alleviates the impact, the roll support member and the roll-form recording material are resistant to deformation and damage.
  • the above-mentioned roll support member comprising the roll support member and the cushioning member has the problem that the cushioning member, which is a low density material, has poor resilience and is deformed by a physical impact such as being dropped.
  • the cushioning member is deformed, thus degrading the cushioning properties.
  • the recording material package receives an impact in this state, the impact is readily transmitted to the roll-form recording material, thus damaging or deforming the roll-form recording material. Because of this, in order to store and transport the roll-form recording material for a long period of time, it is necessary to make the cushioning member larger so that even when the cushioning member is deformed, the cushioning properties can be retained.
  • the cushioning member makes the cushioning member larger requires a large packaging material for it to be housed in, it is disadvantageous in terms of resources and cost, and the space efficiency for its subsequent storage and the efficiency of transporting it are correspondingly degraded. Furthermore, since the roll support member and the cushioning member are molded using different materials, the number of production steps is large, the cost is high, and there are also disadvantages when it is recycled or disposed of after use.
  • An object of the present invention is therefore to provide a roll support member that can support a roll-form recording material without damaging, deforming, or degrading the roll-form recording material even when it is housed in a packaging material and stored or transported for a long period of time, and that can reduce the production cost by making the thickness of the roll support member material thinner.
  • Another object of the present invention is to provide a recording material package that enables efficient storage and transportation to be carried out.
  • a roll support member comprising a four corner-cut rectangular substrate portion, a cylindrical protruding portion that is formed integrally with the substrate portion in the center of the surface on one side of the substrate portion and has the extremity thereof closed, and projecting portions that are formed integrally with the substrate portion so as to extend from each of four corners of the substrate portion in the direction in which the cylindrical protruding portion is formed, wherein the substrate portion has ribs formed on the surfaces of both sides thereof, the cylindrical protruding portion has a hollow interior portion formed therein, the hollow interior portion has a rib disposed in a cylindrical shape that is substantially concentric with the cylindrical protruding portion, and a radial rib disposed so as to provide a connection between the concentric cylindrical rib and the surface on the hollow interior portion side of the cylindrical protruding portion, the side of the substrate portion on which the cylindrical protruding portion is formed is provided with a U-shaped channel in a section where the cylindrical protruding portion and the substrate portion intersect, the channel surrounding the base of the cylindrical
  • the other object of the present invention can be solved by the recording material package below.
  • a roll support member having high resistance to drop impact can be obtained with low cost even when it is made of a thin, low strength material.
  • FIG. 1 shows a schematic perspective view of each member when a roll-form recording material having the roll support member of the present invention mounted on each end thereof is housed in a case.
  • a roll-form recording material 1 wound around a hollow cylindrical core 2 is wrapped with a light-shielding leader 14 and a light-shielding flange 15.
  • Roll support members 3 are preferably made by injection molding.

  • the four corners of the substrate portion 4 are preferably cut off so that an impact will not be concentrated on the corners and break them.

  • the height of the cylindrical protruding portion 3 is preferably in the range of 10 to 40 mm, and more preferably in the range of 20 to 30 mm.
