Description
- This invention relates to a corrugated fibreboard box, and more particularly to a corrugated fibreboard shipping box for packing a stack of sheet materials of a predetermined number.
- In packing a stack of sheet materials such as photosensitive plates consisting of aluminium substrates and photosensitive resin layers disposed thereon, a predetermined number of the sheet materials are stacked together and packed in an interior package and then further packed in a corrugated fibreboard shipping box.
- Corrugated fibreboard shipping boxes are described in US-A-1 677 918. Flaps there are folded to form hollow cushions but they are not folded tightly to form end portions which are "full" of material.
- Also US-A-3 516 593 discloses a shipping box in which the flaps are folded reversally at the end. Therefore those flaps cannot be folded repeatedly many times into tightly folded portions.
- A basic disadvantage of those hollow cushions formed around shipping boxes of the prior art is a lack of stability against knocks and hits from the outside.
- It is the purpose of the invention to improve the stability of corrugated shipping boxes which are able to sufficiently support sheet material having comparatively high weight. Especially stability against knocks and hits should be improved.
- These objects are accomplished by this invention as claimed. Especially in accordance with the present invention as claimed the automatic packing by use of a packing machine is possible.
- The objects, features and advantages of the present invention will be described in further detail with reference to particular embodiments thereof referring to accompanying drawings in which:
- Figure 1 is a plan view of a box blank of the corrugated fibreboard box in accordance with an embodiment of the present invention,
- Figure 2 is a fragmentary sectional view of the corrugated fibreboard box containing a stack of sheet materials in accordance with an embodiment of the present invention as shown in Figure 1,
- Figure 3A is a fragmentary plan view showing a part of a corrugated fibreboard,
- Figure 3B is a sectional view showing a part of the corrugated fibreboard as shown in Figure 3A for explaining the dimensions of the corrugated fibreboard bent,
- Figure 4 is an enlarged fragmentary sectional view of the folded portion of the corrugated fibreboard box in accordance with the embodiment of the present invention as shown in Figure 1, and
- Figure 5 is a perspective view partly broken away of the corrugated fibreboard shipping box in accordance with the embodiment of the present invention as shown in Figure 1 in which a stack of sheet materials are contained.
- Now a preferred embodiment of the present invention will be described in detail with reference to Figures 1 to 5. The structure of the corrugated fibreboard shipping box in accordance with an embodiment of the present invention will best be understood referring to Figures 1 and 2. Referring to Figure 1, the box blank com- proses a
bottom section 1,side sections bottom section 1,top half sections side sections bottom flaps bottom section 1, andtop flaps top half sections flaps side sections adjacent sections - The top section of the corrugated fibreboard shipping box is divided into two
top half sections top half sections - The
flaps end portions - Now the dimensions of the flaps with scores will be described in detail with reference to figures 3A, 3B and 4. In order that a corrugated fibreboard is folded to provide an inner size of C as shown in Figure 3B, the fibreboard must be folded or bent at the folding lines F spaced by a distance C plus the thickness of the fibreboard Th as shown in Figure 3A. When the thickness of the stack of sheet materials to be packed in a shipping box is T, the thickness of the folded
end portions - When the thickness of the folded end portions is to be (B ± a) x (T/2 ± a), the spaces C1 and C2 are made to be (B - Th/2) ± a, and Th ± a. The distances C3, C4 are determined on basis of the distances C1, C2 and the thickness of the corrugated fibreboard Th. Thus, the proper distances C1 to C4 can be simply determined in accordance with the thickness of the stack of sheet materials to be packed.
- The length L1 of the
bottom section 1,side sections top half sections - When the corrugated fibreboard shipping box constructed as described above is used for packing a stack of sheet materials, the
flaps end portions bottom section 1 and the foldedend portions 4P and 6P are located to hold the stack of sheet materials at the end faces of the stack. Then, theside sections top half sections end portions 5P and 7P are brought to the position to hold the stack in the placed position as shown in Figures 2 and 5. The upper foldedend portions 5P and 7P and the lower foldedend portions 4P and 6P are bound together by use of adhesive. Thetop half sections top half sections - In the above described embodiment of the invention, the flaps are provided with four folding lines or scores F1 to F4. It will be understood, however, that the number of the scores is not limited to four but may be properly selected according to the thickness of the stack of sheet materials.
- Further, it is possible to initially provide a number of scores and properly crush some parts between some scores according to the thickness of the stack to be packed, whereby it is prevented to prepare a various kinds of box blanks for different thicknesses of stacks.
- In accordance with the present invention, a corrugated fibreboard shipping box which has a function similar to the conventional fibreboard shipping box provided with shock absorbing pads can be obtained only by folding a box blank. Therefore, the troublesome work for preparing a number of pads and adhering the pads to the predetermined positions of the box can be omitted. Further, in accordance with the corrugated fibreboard shipping box of this invention, the edges and corners of the packed stack of sheet materials are well protected. In addition, the folded end portions formed by the flaps at both of the ends of the top half sections and the bottom section are more advantageous than the folded end portions formed only one of the bottom section and the top half sections in that the strength thereof is improved. Therefore, by the folded end portions having such a high strength is sufficiently able to protect the stack of sheet materials having a large weight such as the photosensitive plates consisting of an aluminium substrate and a photosensitive layer disposed thereon.
