DETAILED DESCRIPTION OF THE INVENTION

[0010] A packaging material according to an embodiment of the present invention, a packaged item packaged with the packaging material, and a packaging method for packaging an item with the packaging material will be described below with reference to the drawings. FIG. 1 is a development view showing the configuration of the packaging material according to this embodiment, FIG. 2 is a perspective view showing the configuration of a package in which an item is packaged with the packaging material according to this embodiment, and FIG. 3 is a perspective view showing the configuration of the packaging material according to this embodiment and the configuration of an item to be packaged with the packaging material. In the following, an XYZ Cartesian coordinate system shown in FIG. 1 is set, and the positional relationship of each part will be described with reference to this Cartesian coordinate system. The X axis is set to the left-right direction on the plane of FIG. 1, the Y axis is set to the up-down direction on the plane of FIG. 1, and the Z axis is set to a direction perpendicular to the plane of FIG. 1.

[0011] As shown in Figure 2, package 1 according to this embodiment is packaged by surrounding packaged item 2 with packaging material 6. As shown in Figures 2 and 3, packaged item 2 according to this embodiment is five stacks 4 of several hundred sheets (e.g., 500 sheets) of copy paper wrapped in wrapping paper, stacked in the Z direction. Below, the positional relationship between packaged item 2 and packaging material 6 will be described, with surface 2c of packaged item 2 being the plane, surface 2d being the left side, surface 2e being the front, the side parallel to the X-axis direction being the horizontal side, the side parallel to the Z-axis direction being the vertical side, and the side parallel to the Y-axis direction being the depth side.

[0012] The packaging material 6 according to this embodiment is made of cardboard and is a packaging material that encloses four sides (flat surface 2c, bottom surface, left side surface 2d, and right side surface) of the packaged item 2, including depth (Y direction) sides 8a to 8c and a depth side not shown. In the unfolded state (the state shown in FIG. 1 ) before enclosing the packaged item 2, the packaging material 6 has a rectangular enclosing portion 10 for enclosing the flat surface 2c, bottom surface, left side surface 2d, and right side surface of the packaged item 2, and a gluing portion 12 at one end in the shorter direction of the enclosing portion 10 (the end on the -X direction side).

[0013] The enclosing part 10 has a rectangular bottom region 10a connected to the overlap part 12, a rectangular right side region 10b connected to the bottom region 10a, a rectangular flat region 10c connected to the right side region 10b, and a rectangular left side region 10d connected to the flat region 10c. The length L1 of the enclosing part 10 in the short side direction (Y direction) is the same as the length L2 of the depth (Y direction) of the packaged item 2. Both ends 16a to 16d and 17a to 17d of the enclosing part 10 in the long side direction (X direction) are located on the horizontal and vertical sides of the packaged item 2 in the packaged state after enclosing the packaged item 6 (the state shown in Figure 2).

[0014] Specifically, the end 16a on the -Y side of the bottom region 10a is located on the horizontal side 20a on the -Z side of the front surface 2e of the packaged item 2 in the packaged state after the wrapping. The end 17a on the +Y side of the bottom region 10a is located on the horizontal side (not shown) on the -Z side of the back surface of the packaged item 2 in the packaged state after the wrapping.

[0015] The -Y side end 16b of the right side region 10b is located on the vertical side 20b on the +X side of the front surface 2e of the packaged item 2 in the packaged state after the enclosure. The +Y side end 17b of the right side region 10b is located on the vertical side (not shown) on the +X side of the back surface of the packaged item 2 in the packaged state after the enclosure. The -Y side end 16c of the flat region 10c is located on the horizontal side 20c on the +Z side of the front surface 2e of the packaged item 2 in the packaged state after the enclosure. The +Y side end 17c of the flat region 10c is located on the horizontal side 21c on the +Z side of the back surface of the packaged item 2 in the packaged state after the enclosure. The -Y side end 16d of the left side region 10d is located on the vertical side 20d on the -X side of the front surface 2e of the packaged item 2 in the packaged state after the enclosure. An end 17d on the +Y direction side of the left side surface region 10d is located on a vertical side 21d on the −X direction side of the back surface of the packaged item 2 in the packaged state after wrapping.

[0016] In addition, "in the packaged state after wrapping, both longitudinal ends 16a to 16d, 17a to 17d of the enclosing portion 10 are positioned on the horizontal sides (20a, 20c, 21c, one side not shown) and vertical sides (20b, 20d, 21d, one side not shown) of the packaged item 2" includes not only the case where the short-side length L1 of the enclosing portion 10 is equal to the depth length L2 of the packaged item 2 (L1 = L2), but also the following cases. That is, this includes cases where (1) the length L1 is 100 mm or more but 0 mm shorter than the length L2, and the ends of the front 2e and back sides of the packaged item 2 protrude from the end of the packaging material 6 by more than 0 mm but 50 mm or less in the packaged state after the surrounding, and (2) the length L1 is 0 mm but less than 20 mm longer than the length L2, and the ends 16a to 16d, 17a to 17d of the packaging material 6 protrude from the end of the front 2e and back sides of the packaged item 2 by more than 0 mm but 10 mm.

[0017] The overlap portion 12 is glued to the other end of the short side of the enclosing portion 10 (left side region 10d) in the packaged state after enclosing the packaged item 6 (the state shown in FIG. 2). When multiple packages 1 shown in FIG. 2 are stacked in the Z direction, the other end of the short side of the enclosing portion 10 (left side region 10d) is located at one of the two bottom edges of the depth of the package 1 (in this embodiment, the bottom edge 1a of the depth on the -X direction side). By positioning the other end of the short side of the enclosing portion 10 (left side region 10d) at the bottom edge 1a of the depth of the package 1, stability is increased when the packages 1 are stacked.

[0018] Next, a packaging method for obtaining a package 1 in which an item 2 to be packaged according to this embodiment is packaged in packaging material 6 using a packaging machine will be described. First, the packaging material 6 is conveyed to the packaging section of the packaging machine by the packaging material conveying section of the packaging machine. Once the packaging material 6 is set in the packaging section of the packaging machine, the item 2 to be packaged is conveyed to the packaging section of the packaging machine by the item conveying section of the packaging machine and placed on the bottom area 10a of the enclosing section 10. At this time, the item 2 to be packaged is placed on the packaging material 6 (bottom area 10a) so that the lateral side 20a of the item 2 to be packaged is positioned at the edge 16a of the bottom area 10a and the lateral side (not shown) on the -Z direction side of the back of the item 2 to be packaged is positioned at the edge 17a of the bottom area 10a.

[0019] Next, in the packaging section of the packaging machine, the fold line 14b between the bottom region 10a and the right side region 10b, the fold line 14c between the right side region 10b and the flat region 10c, and the fold line 14d between the flat region 10c and the left side region 10d are folded in this order, so that the four sides of the packaged item 2, i.e., the bottom, right side, flat region 2c, and left side 2d, are surrounded by packaging material 6. Then, in the packaging section of the packaging machine, the fold line 14a between the overlap portion 12 and the bottom region 10a is folded, and the overlap portion 12 is glued to the Y-direction end of the left side region 10d using adhesive that has been applied to the overlap portion 12 in advance.

[0020] The packaging material 6, packaged item 1, and packaging method according to this embodiment can facilitate opening, reduce costs, and conserve resources. That is, compared to conventional packaging materials that have multiple glued areas, the packaging material 6 has only one glued area, making it easier to open and preventing nail damage during opening. Furthermore, compared to conventional packaging materials that cover the entire surface of the packaged item 2, the packaging material 6 surrounds only the top surface 2c, bottom surface, left side surface 2d, and right side surface of the packaged item 2, and does not cover the front surface 2e and back surface, eliminating the need for cardboard to cover the front surface 2e and back surface. Therefore, compared to conventional packaging materials, the packaging material 6 can reduce material costs and further reduce waste after use.

[0021] In the above-described embodiment, a stack of copy paper 4 was used as an example of the paper bundle. However, other types of paper, such as fine paper or form paper, may also be used. Furthermore, in the above-described embodiment, the packaged item 2 was described as a stack of five paper bundles 4. However, the packaged item may be a stack of two to four or six to ten paper bundles 4. As shown in FIG. 4(A), the packaged item 2' may be two rows of multiple (two to five) paper bundles 4. That is, the packaged section 2' contains a total of four to ten paper bundles 4. In this case, as shown in FIG. 4(B), the packaged item 2' is packaged by surrounding four sides (24a, 24b, and two sides not shown) of the packaged item 2' with a packaging material 6' having a rectangular surrounding section 10' and a flap 12'. This includes the depth sides (22a, 22b, 22c, and a side not shown). [Explanation of symbols]
