Abstract
Description
[Technical Field]
[0001] The present invention relates to a packaging member. [Background technology]
[0002] Conventionally, packaging members that include a packaging box for storing packaged items and a cushioning material placed inside the packaging box have been widely used. The cushioning material is placed outside the storage area for storing the packaged items and protects the packaged items from impacts.
[0003] For example, a conventional packaging unit disclosed in Patent Document 1 includes an upper case and a lower case arranged opposite each other in the vertical direction, and multiple cushioning materials. The upper cushioning material has a storage section for storing the contents of the packaged object. The packaging unit also includes a lid-shaped holding member that is placed over the upper cushioning material. The upper case is placed over the holding member. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Publication No. 2020-147324 Summary of the Invention [Problem to be solved by the invention]
[0005] However, the above-mentioned conventional technology has a problem in that a holding member is required in addition to the upper case, lower case, and cushioning material to hold the packaged items stored in the storage section of the upper cushioning material, which increases the number of parts and raises concerns about the high cost of the packaging unit.
[0006] The present invention has been made in consideration of the above points, and aims to provide a packaging member that can suitably hold and protect packaged items with a low-cost configuration. [Means for solving the problem]
[0007] In order to solve the above problems, the packaging member of the present invention comprises a packaging box and an upper cushioning material. The packaging box has an opening at the top, through which a first packaged item and a second packaged item are inserted and removed. The upper cushioning material is disposed adjacent to the opening above the first packaged item and has an internal storage area for the second packaged item. The packaging box has an outer flap, an inner flap, and a protrusion. The outer flap is provided on the upper edge of the packaging box and is capable of opening and closing the opening. The inner flap is provided on the upper edge of the packaging box and is disposed inside the outer flap when the opening is closed by the outer flap. The protrusion is provided on the inner flap and protrudes toward the storage area in the upper cushioning material and contacts the second packaged item when the opening is closed by the outer flap. [Effects of the Invention]
[0008] According to the configuration of the present invention, the protrusion of the inner flap can hold the second packaged item in the storage area by contacting the second packaged item. By providing the protrusion that holds the second packaged item on the inner flap of the packaging box, there is no need to prepare a separate holding member for the second packaged item. This reduces the number of parts. Therefore, it is possible to provide a packaging member that can optimally hold and protect the packaged items with a low-cost configuration.

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following. In this description, the direction indicated by the arrow D1 in the drawings is the "first direction" (the longitudinal direction of the second packaged item Pr2), and the direction indicated by the arrow D2 is the "second direction" (the lateral direction of the second packaged item Pr2). The first direction D1 and the second direction D2 are perpendicular to each other.
[0011] Fig. 1 is a perspective view of a packaging member 1 of an embodiment. Fig. 2 is a perspective view of the packaging member 1 of Fig. 1, showing a state in which a packaging box 20 has been removed. Fig. 3 is a partial development view of the packaging box 20 of the packaging member 1 of Fig. 1.
[0012] As shown in FIG. 1, the packaging member 1 has an outer shape of a substantially rectangular parallelepiped, and includes a tray-equipped pallet 10, a packaging box 20, and a cushioning material 30.
[0013] The tray-equipped pallet 10 includes a tray 40 and a pallet 50. The tray 40 is fixed to the upper surface of the pallet 50. The tray 40 has a bottom 41 that is rectangular in plan view and four side walls 42. The bottom 41 and the four side walls 42 are formed in the shape of a flat plate. Each of the four side walls 42 is connected to the four sides of the bottom 41 and extends upward.
[0014] The pallet 50 includes a top plate 51 and a bottom plate 52 that are rectangular in plan view, and a plurality of support posts 53. The top plate 51 and the bottom plate 52 are formed in a flat plate shape and have the same shape as the bottom 41 of the tray 40. The top plate 51 is fixed to the bottom 41 of the tray 40 using nails, screws, etc. (not shown). The plurality of support posts 53 are aligned horizontally in a predetermined array, and the top plate 51 and the bottom plate 52 are fixed to the upper and lower ends thereof.
[0015] The packaging box 20 accommodates a first packaged item Pr1 and a second packaged item Pr2 inside. In this embodiment, the first packaged item Pr1 is the main body of the packaged item, and the second packaged item Pr2 is an item bundled with the main body of the first packaged item Pr1. The packaging box 20 is a rectangular parallelepiped with an open bottom, and covers the sides and top of the first packaged item Pr1. The packaging box 20 has an upper opening (opening) 20a that appears when an outer flap 22 and an inner flap 23, which will be described later, are opened. The first packaged item Pr1 and the second packaged item Pr2 are inserted into and removed from the packaging box 20 through the upper opening 20a.
[0016] When the packaging box 20 is unfolded, it becomes the development diagram shown in Fig. 3. Note that Fig. 3 omits the illustration of a part of the packaging box 20 (the left side of Fig. 3). The packaging box 20 is a single sheet material (blank) that has a substantially rectangular outer shape when unfolded and flat, and is made of, for example, cardboard. That is, the packaging box 20 is formed by folding a single sheet material.
[0017] The packaging box 20 has four side walls 21, two outer flaps 22, and two inner flaps 23. Each of the side walls 21, the outer flaps 22, and the inner flaps 23 is formed in a flat plate shape that is rectangular in plan view.
[0018] The four side walls 21 are connected in one direction (the left-right horizontal direction in FIG. 3) in the packaging member 1 made of a flat sheet material. The four side walls 21 are connected at both ends in the connecting direction (the left-right horizontal direction in FIG. 3) to form a rectangular tube shape extending in the up-down direction as shown in FIG. 1. The four side walls 21 are arranged overlapping on the inside of the four side walls 42 of the tray 40 in the packaging member 1 in the assembled state shown in FIG.
[0019] The two outer flaps 22 and the two inner flaps 23 are each provided on the upper edge of the packaging box 20. In other words, the two outer flaps 22 and the two inner flaps 23 are each connected to the upper edges of the four side wall portions 21. The two outer flaps 22 are connected to two sides of the side wall portion 21 that face each other in the horizontal direction. The two inner flaps 23 are perpendicular to the outer flaps 22 and are connected to two sides of the other side wall portion 21 that face each other in the horizontal direction.
[0020] The two outer flaps 22 have a rectangular shape in a plan view and can close the upper opening 20a when aligned horizontally. That is, the two outer flaps 22 can open and close the upper opening 20a. The two inner flaps 23 are positioned inside (below) the two outer flaps 22 when the upper opening 20a is closed by the two outer flaps 22. The detailed configuration of the inner flaps 23 will be described later.
[0021] The cushioning material 30 is placed in the gap between the first packaged item Pr1 and the packaging box 20 to protect the first packaged item Pr1 from impact. The cushioning material 30 is formed, for example, by folding a cardboard sheet into a predetermined shape. The cushioning material 30 includes side cushioning materials 31 and an upper cushioning material 32.
[0022] The side cushioning materials 31 are arranged to cover the four corners of the side surfaces of the first packaged item Pr1. When viewed from the top and bottom, the side cushioning materials 31 are formed in an L-shape, and extend vertically along the corners of the first packaged item Pr1. The upper cushioning material 32 is arranged above the first packaged item Pr1, adjacent to the top opening 20a. The upper cushioning material 32 has an internal storage area S for the second packaged item Pr2. The detailed configuration of the upper cushioning material 32 will be described later.
[0023] Next, detailed configurations of the inner flap 23 and the upper cushioning material 32 will be described using Figures 4 to 7 in addition to Figures 1 to 3. Figures 4 and 5 are a cross-sectional perspective view and a vertical cross-sectional view of the packaging member 1 of Figure 1. Figures 6 and 7 are partial perspective views of the upper cushioning material 32 and inner flap 23 of the packaging member of Figure 1.
[0024] The upper cushioning material 32 has a storage section 321 for the second packaged item Pr2. When the upper opening 20a is closed by the two outer flaps 22, the storage section 321 is located inside (below) the inner flap 23 having a protrusion 231 described below.
[0025] 4, 5, and 6, the accommodating section 321 is formed with a U-shaped cross section when viewed from the first direction D1, which is the horizontal direction of the packaging member 1. A storage area S for the second packaged item Pr2 is provided inside the accommodating section 321. The accommodating section 321 stores the second packaged item Pr2, which is a long member extending in the first direction D1.
[0026] The storage section 321 has a bottom 321a and a pair of side walls 321b. The bottom 321a has a rectangular shape in plan view that extends elongatedly in the first direction D1 when viewed from the top-bottom direction. The pair of side walls 321b are connected to both ends of the bottom 321a in the second direction D2.
[0027] The pair of side walls 321b are arranged opposite both ends of the storage section 321 in the second direction D2, with the storage area S in between. Each of the pair of side walls 321b has a rectangular shape extending long in the first direction D1 when viewed from the opposing direction (second direction D2). The pair of side walls 321b are formed by bending upward from the peripheral edges (both ends in the second direction D2) of the bottom 321a. The second packaged item Pr2 is arranged adjacent to one of the pair of side walls 321b that is closer to the side wall 21 of the packaging box 20 within the storage area S, and extends in the first direction D1.
[0028] The inner flap 23 has a protrusion 231. As shown in Figures 1, 4 and 5, the protrusion 231 is provided on the inner surface side of the inner flap 23. The protrusion 231 protrudes toward the storage area S in the upper cushioning material 32 when the outer flap 22 closes the upper opening 20a. In other words, the protrusion 231 is provided on the inner flap 23 located above the storage area 321 of the upper cushioning material 32 when the outer flap 22 closes the upper opening 20a. The protrusion 231 comes into contact with the second packaged item Pr2 from above in the storage area S in the upper cushioning material 32.
[0029] According to the above configuration, the protrusion 231 of the inner flap 23 comes into contact with the second packaged item Pr2, thereby holding the second packaged item Pr2 in the storage area S. By providing the protrusion 231 that holds the second packaged item Pr2 on the inner flap 23 of the packaging box 20, there is no need to prepare a separate holding member for the second packaged item Pr2. This reduces the number of parts. Therefore, it is possible to provide a packaging member 1 that can optimally hold and protect packaged items with a low-cost configuration.
[0030] Furthermore, when the upper opening 20a of the packaging box 20 is opened, the second packaged item Pr2 can be easily released from the protrusion 231 at the same time as the inner flap 23 is opened. This makes it possible to improve the workability when opening the package.
[0031] In this embodiment, the inner flap 23 has two protrusions 231. The two protrusions 231 are arranged side by side in the first direction D1, that is, in the longitudinal direction of the second packaged item Pr2.
[0032] Furthermore, the protrusion 231 is formed using a part of the inner flap 23. More specifically, the protrusion 231 is formed by cutting out a part of the flat inner flap 23 and forming it into a shape that protrudes toward the storage area S in the upper cushioning material 32. With this configuration, the protrusion 231 can be easily formed as a holding portion for the second packaged item Pr2 using a part of the inner flap 23.
[0033] The protrusion 231 is formed as a cut-and-raised piece 231S on the inner flap 23 of the packaging box 20 made of sheet material shown in Fig. 3. The protrusion 231 is formed in a triangular shape when viewed from the second direction D2 by folding the cut-and-raised piece 231S toward the inside (downward) of the inner flap 23 along three fold lines 23f that are spaced apart in the first direction D1 and extend in the second direction D2 (see Fig. 7).
[0034] The protrusion 231 has an engagement groove 231g penetrating the sheet material in the thickness direction, and the inner flap 23 has an engagement piece 23e arranged in the first direction D1 at a distance from the cut-and-raised piece 231S. The engagement piece 23e is also cut and raised to have a rectangular shape.
[0035] The engagement groove 231g faces adjacent to the engagement piece 23e when the cut-and-raised piece 231S is bent into a triangle to form the protrusion 231. The engagement piece 23e is inserted into the engagement groove 231g. The length of the engagement piece 23e in the second direction D2 is equal to or longer than that of the engagement groove 231g, and the engagement piece 23e fits into the engagement groove 231g.
[0036] As described above, the protrusion 231 is formed by bending it in a V shape toward the storage area S for the second packaged item Pr2 in the upper cushioning material 32. With this configuration, the protrusion 231, which serves as a holding portion for the second packaged item Pr2, can be formed with a strong configuration. This makes it possible to optimally hold and protect the second packaged item Pr2.
[0037] 4, 5, and 6, the storage section 321 of the upper cushioning material 32 has a holding piece 321h. The holding piece 321h is arranged in the center in the first direction D1 within the storage area S for the second packaged item Pr2. The holding piece 321h is formed by cutting out a portion of the bottom 321a of the upper cushioning material 32. In other words, the holding piece 321h is formed by lifting up a portion of the center in the first direction D1 of the bottom 321a. The holding piece 321h holds the second packaged item Pr2 by sandwiching it between itself and the inner bottom of the storage section 321.
[0038] According to the above configuration, by providing the protrusion 231 and the holding piece 321h as a holding portion for the second packaged item Pr2, it is possible to enhance the effect of holding and protecting the second packaged item Pr2 in the storage portion 321. It is also possible to prevent the second packaged item Pr2 from being completely released from its hold upon opening the inner flap 23. This makes it possible to prevent the second packaged item Pr2 from unintentionally falling out of the storage portion 321 when the inner flap 23 is opened.
[0039] The holding piece 321h may be formed by cutting out a part of the side wall portion 321b of the upper cushioning material 32 and raising it.
[0040] As described above, the inner flap 23 has two protrusions 231. The two protrusions 231 are arranged on both outer sides of the holding piece 321h, sandwiching the holding piece 321h, in the first direction D1, i.e., the longitudinal direction of the second packaged item Pr2.
[0041] The above configuration makes it possible to prevent one side of the second packaged item Pr2 in the longitudinal direction (first direction D1) from being displaced in the second direction D2 in the storage section 321. This makes it possible to improve the function of holding and protecting the second packaged item Pr2 in the storage section 321.
[0042] The number of protrusions 231 is not limited to two, but may be one, or three or more.
[0043] Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these, and various modifications can be made without departing from the spirit of the invention. [Industrial Applicability]
[0044] The present invention can be used in packaging members including packaging boxes that contain packaged items. [Explanation of symbols]
