Description

[Technical Field]

[0001] The present invention relates to a packaging device for packaging an object to be packaged. [Background technology]

[0002] With the spread of mail-order sales such as online shopping, the transportation of goods using home delivery services is becoming more common. In transporting these goods, packaging devices that can stably transport various packaged items of different shapes and sizes are required.

[0003] A conventionally known example of this type of packaging device is a packaging box consisting of a packaging device made of a cardboard plate-shaped member and a tubular, stretchable, flexible film member in which the plate-shaped member is housed, and a cardboard box that houses the packaging device (see Patent Document 1).

[0004] In this packaging device, the plate-like member has a placing section on which the item to be packaged is placed and standing sections arranged on both sides of the placing section, and a first fold line is provided at the boundary between the placing section and the standing sections, which allows the standing sections to be valley-folded above the placing section, and a second fold line is perpendicular to the first fold line, which allows the placing section and the folded-back section to be valley-folded.

[0005] When packaging an object to be packaged using this packaging device, the plate-like member is valley-folded along the second fold line to create a gap between the plate-like member and the flexible film member, and the object to be packaged is then inserted. When each upright portion is then folded upward from the first fold line, the previously folded second fold line is restored to its original, unfolded state, causing tension in the flexible film member.

[0006] As a result, the object to be packaged is supported by being pressed against the placing portion by the flexible film member. This packaging device, with the object to be packaged wrapped, is placed in an outer box such as a cardboard box and transported as a package box. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Special Publication No. 9-501128 Summary of the Invention [Problem to be solved by the invention]

[0008] However, this type of packaging device has the disadvantage that, because it uses a flexible film member, it must be separated from the cardboard when it is disposed of.

[0009] In view of the above, an object of the present invention is to provide a packaging device that is easy to dispose of. [Means for solving the problem]

[0010] In order to achieve this object, a packaging device according to a first aspect of the present invention is a packaging device comprising a plate-shaped member on which an item to be packaged is placed, and wrapping paper capable of covering at least the item to be packaged placed on the plate-shaped member, wherein the plate-shaped member has a placing section on its surface on which the item to be packaged is placed, upright sections connected to both the left and right sides of the placing section via a first fold line extending in the vertical direction, and a second fold line extending in the horizontal direction connecting the ends of the left and right upright sections, the wrapping paper being tubular with openings on the left and right sides into which the plate-shaped member is inserted, and having a mesh section that stretches in the vertical direction at least in the area covering the placing section, the mesh section having multiple perforations in the vertical direction, in which unit cuts and unprocessed sections are arranged alternately on a straight line extending in the horizontal direction, and the arrangement of the unit cuts and the unprocessed sections is staggered in the vertical direction, and the unit cuts adjacent in the vertical direction are formed so that they partially overlap each other when viewed in the vertical direction.

[0011] In the first packaging device of the present invention, a plate-shaped member is inserted into a tubular wrapping paper, and by valley-folding this plate-shaped member along the second fold line, the gap between the mounting portion of the plate-shaped member and the wrapping paper can be increased, making it easy to insert the item to be packaged.

[0012] Furthermore, standing portions are connected to both sides of the placing portion via a first fold line, and since the first fold line and the second fold line intersect, when both standing portions are folded along the first fold line, the second fold line that was previously folded is forcibly restored to an unfolded state, and the wrapping paper is pulled in the vertical direction by the upper and lower ends of the plate-shaped member.

[0013] In this case, the wrapping paper of the first invention has a mesh portion that is formed so that there are multiple perforations in the vertical direction, in which unit cuts and unprocessed sections are arranged alternately on a straight line extending in the left-right direction, and the arrangement of the unit cuts and the unprocessed sections is staggered in the vertical direction, and adjacent unit cuts in the vertical direction partially overlap each other when viewed along the vertical direction, so that it can expand and contract in the vertical direction, and can support the object to be packaged by pressing it against the loading section while being pulled by the upper and lower ends of the plate-shaped member.

[0014] Conventional packaging devices mainly use transparent flexible film members, allowing the packaged object to be seen through the film, but the packaging device of the present invention uses wrapping paper, which poses a new problem in that if the entire packaged object is covered with wrapping paper, it becomes difficult to see what is contained in the packaging device.

[0015] In this regard, in the first packaging device of the present invention, when the wrapping paper is pulled, each unit cut opens into a hexagonal shape, and through this opening it is possible to determine what packaged item is stored in the packaging device before opening it.

[0016] Furthermore, since the plate-like members and wrapping paper that make up the packaging device of the first aspect of the present invention are both made of paper, there is no need to separate them when disposing of them, making disposal easy.

[0017] In addition, a packaging device according to a second aspect of the present invention is a packaging device comprising a plate-shaped member on which an item to be packaged is placed, and wrapping paper capable of covering at least the item to be packaged placed on the plate-shaped member, wherein the plate-shaped member comprises a placing section on its surface on which the item to be packaged is placed, upright sections connected to both the left and right sides of the placing section via a first fold line extending in the vertical direction, and a second fold line extending in the horizontal direction connecting the ends of the left and right upright sections, the wrapping paper covering the placing section and having its upper and lower ends fixed to the back side of the plate-shaped member, respectively, and a mesh section that stretches in the vertical direction is provided in at least the area covering the placing section, the mesh section having multiple perforations in the vertical direction, in which unit cuts and unprocessed sections are arranged alternately on a straight line extending in the horizontal direction, the mesh section being formed so that the arrangement of the unit cuts and the unprocessed sections alternates in the vertical direction, and the unit cuts adjacent in the vertical direction partially overlap each other when viewed in the vertical direction.

[0018] In the second packaging device of the present invention, the wrapping paper covers the surface of the mounting portion, and its upper and lower ends are fixed to the back side of the plate-shaped member, respectively.By valley-folding the plate-shaped member along the second fold line, the gap between the mounting portion of the plate-shaped member and the wrapping paper can be increased, making it easy to insert the item to be packaged.

[0019] Furthermore, standing portions are connected to both sides of the placing portion via a first fold line, and since the first fold line and the second fold line intersect, when both standing portions are folded along the first fold line, the second fold line that was previously folded is forcibly restored to an unfolded state, and the wrapping paper is pulled in the vertical direction by the upper and lower ends of the plate-shaped member.

[0020] At this time, since the wrapping paper of the second invention has a mesh portion, it can stretch in the vertical direction, and as it is pulled by the upper and lower ends of the plate-like member, it can stretch and press the object to be wrapped against the placing portion to support it.

[0021] In addition, in the second packaging device of the present invention, when the wrapping paper is pulled, each unit cut opens in a hexagonal shape, and through this opening it is possible to determine what packaged item is stored in the packaging device before opening it.

[0022] Furthermore, since the plate-like members and wrapping paper that make up the packaging device of the second invention are both made of paper, there is no need to separate them when disposing of them, making disposal easy.

[0023] Furthermore, a packaging device according to a third aspect of the present invention is a packaging device comprising a plate-shaped member on which an object to be packaged is placed, and wrapping paper capable of covering at least the object to be packaged placed on the plate-shaped member, wherein the plate-shaped member comprises a placing section on the surface of which the object to be packaged is placed, upright sections connected to both the left and right sides of the placing section via a first fold line extending in the vertical direction, and a second fold line extending in the horizontal direction connecting the ends of the left and right upright sections, the upper and lower ends of the wrapping paper being fixed to the surface of the plate-shaped member on both the top and bottom sides of the second fold line, and a mesh section that stretches in the vertical direction is provided in at least the area covering the placing section, the mesh section having multiple perforations in the vertical direction, in which unit cuts and unprocessed sections are arranged alternately on a straight line extending in the horizontal direction, and the arrangement of the unit cuts and the unprocessed sections is staggered in the vertical direction, and the unit cuts adjacent in the vertical direction are formed so that they partially overlap each other when viewed in the vertical direction.

[0024] In the third packaging device of the present invention, the upper and lower ends of the wrapping paper are fixed to the surface of the plate-shaped member on both the upper and lower sides of the second fold line, so that by valley-folding the plate-shaped member along the second fold line, the gap between the mounting portion of the plate-shaped member and the wrapping paper can be increased, making it easy to insert the item to be packaged.

[0025] Furthermore, since the upright portions are connected to both sides of the placement portion via the first fold line and the first fold line intersects with the second fold line, when both upright portions are folded along the first fold line, the previously folded second fold line is forcibly restored to its unfolded state. Then, since the upper and lower ends of the wrapping paper are fixed to both the upper and lower sides of the second fold line of the plate-like member, the wrapping paper is pulled in the vertical direction.

[0026] At this time, since the wrapping paper of the second invention has a mesh portion, it can stretch in the vertical direction, and as it is pulled by the upper and lower ends of the plate-like member, it can stretch and press the object to be wrapped against the placing portion to support it.

[0027] In addition, in the second packaging device of the present invention, when the wrapping paper is pulled, each unit cut opens in a hexagonal shape, and through this opening it is possible to determine what packaged item is stored in the packaging device before opening it.

[0028] Furthermore, since the plate-like members and wrapping paper that make up the packaging device of the second invention are both made of paper, there is no need to separate them when disposing of them, making disposal easy.

[0029] In the packaging device according to the present invention, the unit cuts are preferably wavy.

[0030] When the wrapping paper of the present invention is pulled and each unit cut opens into a hexagonal shape, it rises in directions that intersect the up-down and left-right directions, so the cut edge of the unit cut comes into contact with the object to be packaged. Therefore, if the unit cut is wavy, the cut edge only comes into point contact with the object to be packaged, reducing the possibility of the cut edge damaging the object to be packaged.

[0031] In addition, in the packaging device according to the present invention, it is preferable that the mesh portion is provided at a position spaced apart from the object to be packaged in the vertical direction.

[0032] A packaging device having this configuration can ensure stretchability when supporting an object to be packaged, while reducing the possibility of the object being damaged by the cut end surfaces of the unit cuts.

[0033] In addition, in the packaging device according to the present invention, it is preferable that the mesh portion is provided in the middle portion in the left-right direction, at a position where it comes into contact with the object to be packaged.

[0034] With a packaging device further having this configuration, when the packaging object is supported in the middle part in the left-right direction, the left and right sides of the middle part do not have a mesh part formed and are less likely to stretch, so the packaging object can be prevented from falling out.

[0035] In addition, in the packaging device according to the present invention, it is preferable that the mesh portion is provided at a position spaced apart from the upper and lower end edges of the plate-like member.

[0036] According to a packaging device further having this configuration, the unprocessed portion is broken at the upper and lower edges of the plate-like member and connected to the unit cuts, thereby preventing holes from being made in the mesh portion. [Brief explanation of the drawings]

[0038] A first embodiment of the present invention will be described with reference to the drawings.

[0039] As shown in Fig. 1, a packaging device 1 for transporting goods (hereinafter referred to as packaging device 1) of the first embodiment has a plate-shaped member 2 and wrapping paper 3. The packaging device 1 holds an object to be packaged K between the plate-shaped member 2 and the wrapping paper 3, and is housed in an outer box (not shown) made of cardboard.

[0040] The plate-shaped member 2 is a substantially rectangular corrugated cardboard sheet. As shown in FIG. 2, the plate-shaped member 2 is divided into a placing portion 21 and upright portions 22, 22 disposed on both sides of the placing portion 21.

[0041] The placing section 21 is a horizontally long rectangular section on which the packaging object K secured in the central region of the plate-like member 2 is placed. The standing sections 22 are vertically long rectangular sections that are connected to the left and right edges of the placing section 21 via first fold lines a (corresponding to the "first fold line" of the present invention) and are folded upward.

[0042] The first fold line a is a fold line that allows for a valley fold and is parallel to the left and right edges of the plate-like member 2. The first fold line a is formed by providing a crease on the surface.

[0043] This allows the standing portion 22 to be bent to a position facing upward and generally perpendicular to the placing portion 21.

[0044] A second fold line b (corresponding to the "second fold line" of the present invention) that passes through the placing portion 21 and the standing portions 22, 22 and intersects with the first fold lines a, a is formed in the plate-like member 2. The second fold line b is a fold line that is parallel to the upper and lower edges of the plate-like member 2 and allows for a valley fold.

[0045] 1 is formed into a cylindrical shape by overlapping and fixing the upper and lower ends with an adhesive, and the plate-like member 2 is inserted from one opening in the direction along the second fold line b. The wrapping paper 3 needs to be formed so as to cover at least the packaging object K in the axial direction, and in the first embodiment, it is formed so as to cover most of the placing portion 21.

[0046] The length of the wrapping paper 3 in the circumferential direction is designed to be approximately the same as the outer periphery of the plate-shaped member 2 in the short side direction or slightly larger so that the plate-shaped member 2 can be housed therein.

[0047] As shown in FIG. 1 (partially enlarged) and FIG. 3, the wrapping paper 3 has a mesh portion 31 formed on the entire surface.

[0048] The mesh portion 31 is configured by a plurality of perforations 32 extending in the left-right direction and formed at equal intervals in the up-down direction.

[0049] The perforations 32 are formed by alternately arranging unit cuts 33 and unprocessed portions 34 on a straight line extending in the left-right direction. The perforations 32 adjacent to one perforation 32 above and below are formed so that the arrangement of the unit cuts and the unprocessed portions alternates in the up-down direction, and the unit cuts adjacent to one another in the up-down direction are formed so that they partially overlap each other when viewed in the up-down direction.

[0050] As a result, as shown in Figure 3, the wrapping paper 3 can expand and contract between a normal state (Figure 3A) and a vertically stretched state (Figure 3B). Specifically, the unit cuts 33 open into a roughly hexagonal shape, and the roughly hexagonal shapes are connected by unprocessed portions 34 extending in the left-right direction, transforming into a mesh shape.

[0051] When the mesh portion 31 opens, the wrapping paper 3 stands up in a direction (front and back directions in FIG. 3B) intersecting the horizontal direction (up and down directions and left and right directions).

[0052] Next, a procedure for packaging an item K using the packaging device 1 will be described with reference to FIGS. 4A to 4C.

[0053] First, as shown in Fig. 4A, the plate-shaped member 2 is folded in a valley fold along the second fold line b. Next, the object to be packaged K is inserted between the placement portion 21 of the plate-shaped member 2 and the wrapping paper 3. At this time, as described above, folding the plate-shaped member 2 in advance causes the wrapping paper 3 to slacken, making it easier to insert the object to be packaged K.

[0054] Next, as shown in Fig. 4B, the plate-like member 2 folded along the second fold line b is restored to a flat plate shape against the tension caused by the elasticity of the wrapping paper 3. As a result, the wrapping paper 3 is pulled toward the upper and lower edges of the placing section 21 and becomes taut, pressing the packaging object K against the placing section 21. As a result, the packaging object K is fixed in a predetermined position.

[0055] Furthermore, as shown in FIG. 4B, the standing portions 22, 22 are folded along the first fold lines a, a toward the front surface of the placement portion 21 (in the direction of the arrows in FIG. 4B).

[0056] As a result, the standing portion 22 gradually stands up, and stands above the placement portion as shown in FIG. 4C.

[0057] With the above, the packaging of the object K to be packaged using the packaging device 1 is completed.

[0058] 4B, the plate-like member 2 bent along the second fold line b is returned to its original unfolded state, and then the standing portions 22, 22 are folded along the first fold lines a, a toward the front surface of the mounting portion 21. However, since the second fold line b and the first fold line a intersect, both fold lines cannot be folded simultaneously. Therefore, the second fold line b, which was previously bent, is automatically restored to its original state (unfolded state) by forcibly bending the first fold line a.

[0059] Finally, the packaging device 1 is placed in a cardboard outer box (not shown), and the product is transported by a parcel delivery service or the like.

[0060] According to the packaging device 1 of the first embodiment described above, the packaging object K can be supported on the placement portion by the packaging paper 3 without using a conventional flexible film member.

[0061] Furthermore, since the packaging device 1 has mesh portions 31 provided on the entire surface of the wrapping paper 3, the packaging object K also comes into contact with the mesh portions 31. Therefore, the packaging object K is frictionally engaged by the unevenness of the multiple mesh portions 31, and is less likely to slip on the placing portion 21.

[0062] Furthermore, since the net portion 31 of the packaging device 1 opens in a mesh shape, the contents wrapped in the wrapping paper 3 can be seen before opening it. Note that, since this window portion 32 is sufficiently small compared to the size of the object K to be packaged, the object K to be packaged will not fall through the window portion 32 and become detached from the packaging device 1.

[0063] Furthermore, since the plate-like members and wrapping paper that constitute the packaging device 1 are both made of paper, there is no need to separate them when disposing of them, making disposal easy.

[0064] Next, another embodiment will be described with reference to FIGS.

[0065] In the first embodiment, the wrapping paper 3 is formed into a cylindrical shape by overlapping the upper and lower ends and fixing them with an adhesive, but the present invention is not limited to this.

[0066] That is, as shown in FIG. 5A, the wrapping paper 3 may cover the surface of the placing portion 21, and the upper and lower ends thereof may be fixed to the back side of the placing portion 21 with adhesive G (second embodiment).

[0067] According to the second embodiment, unlike the cylindrical wrapping paper 3, the wrapping paper 3 is fixed to the plate-like member 2, so that the wrapping paper 3 does not unintentionally fall off from the plate-like member 2 before use.

[0068] Furthermore, as shown in FIG. 5B, the upper and lower ends of the wrapping paper 3 may be fixed to the upper and lower ends of the placing portion 21 with adhesive G (third embodiment).

[0069] According to the third embodiment, unlike the cylindrical wrapping paper 3, the wrapping paper 3 does not need to cover the back side of the plate-like member 2, and the amount of wrapping paper 3 used can be reduced.

[0070] In the third embodiment, the upper and lower ends of the wrapping paper 3 are fixed to the upper and lower ends of the placing portion 21 as an example, but the adhesive position is not limited to the upper and lower ends as long as it is fixed to both the upper and lower sides of the second fold line b.

[0071] Next, other modifications will be described.

[0072] In the first embodiment, the mesh portion 31 is formed on the entire surface of the wrapping paper 3, but the present invention is not limited to this.

[0073] That is, as shown in Figure 6A, the wrapping paper 3 may have a mesh portion 31 only in the central portion in the vertical and horizontal directions of the front side of the plate-shaped member 2 (more specifically, at a position spaced apart from the upper and lower edges of the plate-shaped member 2, and in the middle portion in the horizontal direction, at a position that comes into contact with the item to be wrapped) (fourth embodiment).

[0074] According to the fourth embodiment, when the packaging object K is supported in the middle part in the left-right direction, the left and right sides of the middle part do not have a mesh part formed thereon and are therefore less likely to stretch, thereby preventing the packaging object K from falling out.

[0075] Furthermore, if the mesh portion 31 is formed on the entire surface of the wrapping paper 3, when the wrapping paper 3 is pulled toward the upper and lower edges of the placing portion 21, the unprocessed portion 34 may break at the upper and lower edges of the plate-like member 2 and connect with the unit cuts, causing holes to form in the mesh portion.

[0076] In contrast, according to the fourth embodiment, there is no mesh portion 31 in the area that contacts the upper and lower edges of the plate-like member 2, so that the unprocessed portion 34 of the mesh portion 31 can be prevented from being broken at the upper and lower edges.

[0077] Furthermore, as shown in FIG. 6B, the wrapping paper 3 may not have the mesh portion 31 formed in the area that comes into contact with the wrapping object K, but may have the mesh portion formed only in the other area (fifth embodiment).

[0078] As described above, when the mesh portion 31 opens, the wrapping paper 3 rises in a direction (front / back direction in Figure 3B) that intersects the horizontal direction (up / down and left / right directions). Therefore, in the first embodiment in which the mesh portion 32 is provided on the entire surface of the wrapping paper 3, the cut end surface of the unit cut may come into contact with the item to be wrapped K and be damaged.

[0079] In contrast to this, according to the fifth embodiment, there is no mesh portion 31 in the area that comes into contact with the packaging object K, so the packaging object K is not damaged by the cut end surface.

[0080] Next, a modified example of the plate-like member 2 will be described with reference to FIG.

[0081] The plate-like member 20 according to the modified example is a substantially rectangular corrugated cardboard sheet. The plate-like member 20 is weighted and has clamping portions 23 at the top and bottom ends in the center in the left-right direction.

[0082] As shown in Figure 7, taking the clamping portion 23 on the lower end side as an example, the clamping portion 23 has a pair of notches 24, 24 extending upward from the lower edge, a pair of rotational fold lines c, c that are connected to the notches 24 and extend in the left-right direction toward the center, and a convex-concave cut line 25 that connects the pair of rotational fold lines c, c.

[0083] The clamping portion 23 can be raised by swinging it to the front side (or back side) of the plate-shaped member 20 along the rotation fold line c, and at this time, the clamping portion 23 comes out along the concave-convex cut line 25, thereby forming corresponding concave-convex and convex-concave portions and concave-convex portions on the lower end side of the plate-shaped member 20 and the upper end side of the clamping portion 23, respectively.

[0084] In addition, since the concave-convex cut line 25 is formed in an uneven shape at a position away from the rotation fold line c toward the lower end of the plate-shaped member 20, a space is created between the upper edge and the surface of the plate-shaped member when the clamping portion 23 is erected.

[0085] Then, when the wrapping paper 3 is inserted into this space from the center of the surface of the plate-shaped member 20 and the raised clamping portion 23 is returned to its original state, the wrapping paper 3 is clamped by the unevenness on the lower end side of the plate-shaped member 20 formed by the uneven cutting line 25 and the unevenness on the upper end side of the clamping portion 23.

[0086] Therefore, by clamping the wrapping paper 3 between the upper and lower clamping portions 23, the wrapping paper 3 can be formed into a cylindrical shape using adhesive, or the wrapping paper 3 can be attached to the plate-shaped member 20 without being glued to the plate-shaped member 2.

[0087] Therefore, the packaging device 1 including the plate-like member 20 does not require the use of adhesive, making it more environmentally friendly.

[0088] Next, other modifications common to the first to fifth embodiments will be described.

[0089] Although the plate-shaped member 2 in the above embodiment is formed of corrugated cardboard, it may be made of thick paper. Also, in the above embodiment, the plate-shaped member 2 is described as being substantially rectangular, but the plate-shaped member 2 is not limited to this and may be polygonal, circular, or elliptical as long as it has first fold lines a, a and second fold line b.

[0090] In the above embodiment, the first fold line a is described as a valley fold and the standing portion 22 is folded upward, but the present invention is not limited to this, and the first fold line a may be a mountain fold and the standing portion 22 may be folded downward.

[0091] In the above embodiment, the first fold line a is described as a fold line parallel to the left and right edges of the plate-like member 2, but it may be a curve with a slight radius.

[0092] In the above embodiment, the first fold line a is described as being formed by creating a line on the surface, but it may also be formed by creating a line on the back, or by cutting in half or by perforating.

[0093] In the above embodiment, the first fold line a, a and the second fold line b are described as being perpendicular to each other, but the present invention is not limited to this and they may simply intersect, and the second fold line b may diagonally connect the left and right edges of the plate-like member 2.

[0094] In the above embodiment, the wrapping paper 3 is described as being formed into a cylindrical shape by overlapping the upper and lower ends and fixing them with adhesive, but it can also be fixed with adhesive tape or double-sided tape.

[0095] In the above embodiment, the plate-shaped member 2 is simply inserted from one opening of the tubular wrapping paper 3 in a direction along the second fold line b, but the wrapping paper 3 and the plate-shaped member 2 can also be fixed to each other on their back surfaces with adhesive G.

[0096] In the above embodiment, the wrapping paper 3 is described as being formed so as to cover roughly the entire loading section 21, but as long as it is capable of supporting the packaging object K, it is sufficient that it covers at least a portion of the packaging object K in the axial direction.

[0097] In the above embodiment, the circumferential length of the wrapping paper 3 is designed to be approximately the same as or slightly larger than the outer periphery in the short side direction of the plate-shaped member 2 so that the plate-shaped member 2 can be stored therein, but if the height of the object to be packaged K is large, it is necessary to increase the circumferential length of the wrapping paper 3. In other words, the circumferential length of the wrapping paper 3 can be selected appropriately depending on the size of the object to be packaged K to be stored therein.

[0098] In the above embodiment, the unit cut 33 is described as being linear, but the unit cut may have a wave shape such as a sine wave, a sawtooth wave, or a triangular wave.

[0099] As described above, when the mesh portion 31 opens, the wrapping paper 3 rises in a direction (front / back direction in Figure 3B) that intersects the horizontal direction (up / down and left / right directions), so the cut end surface of the unit cut may come into contact with the item to be wrapped K and be damaged.

[0100] In contrast, if the unit cuts are formed in a wave shape, the cut end surfaces will only come into point contact with the packaging object K, reducing the possibility of the packaging object being damaged by the cut end surfaces.

[0101] In the above-mentioned fourth embodiment, Figure 6A shows an example in which the mesh portion 31 is provided only in the central portion in the vertical and horizontal directions of the front side of the plate-like member 2, but the mesh portion 31 may be provided over the entire vertical direction as long as it is in the middle portion in the horizontal direction, or may be provided over the entire horizontal direction as long as it is located away from the upper and lower edges of the plate-like member.

[0102] In the above fifth embodiment, Figure 6B was shown and explained to form a mesh portion 31 in an area of the surface of the plate-shaped member 2 that does not come into contact with the packaged item K. However, as in the first and third embodiments, if the wrapping paper 3 reaches the back surface of the plate-shaped member 2, the mesh portion 31 may be provided only on the wrapping paper 3 on the back surface side of the plate-shaped member 2.

[0103] In addition, in this embodiment, an example has been described in which the mesh portion 31 is formed uniformly over a certain area of the wrapping paper 3, but the present invention is not limited to this, and the tension of the wrapping paper 3 can also be adjusted by arranging multiple mesh portions 31, for example, alternating between areas where the mesh portion 31 is formed and areas where it is not formed.
