Description

[Technical field]

[0001] The present invention relates to packaging materials. [Background technology]

[0002] Conventionally, packaging materials have been disclosed that are formed so that the packaged items can be packaged and stored in a packaging box. For example, the packaging material disclosed in Patent Document 1 has a cushioning material made of polystyrene foam or the like provided on a sheet-like support material made of cardboard or the like. This cushioning material has an inclined surface that abuts against the inner side wall of the packaging box, so that the packaged items are less likely to tip over when the packaging box is transported after storing the packaged items therein.

[0003] [Patent Document 1] Jpn. Jpn. Published No. 49-29976 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional packaging materials, the cushioning material is attached to a sheet-like support material, which requires a lot of work to manufacture the packaging material, and it is sometimes difficult to separate the cushioning material and the support material even when it is desired to separate and dispose of them. Therefore, there is a demand for packaging materials that are made only of sheet materials such as cardboard.

[0005] An object of the present invention is to provide a packaging material that can prevent a packaged item from tipping over even when the packaging material is formed of only a sheet material and the packaged item is placed in a packaging box. [Means for solving the problem]

[0006] The packaging material of the present invention has a first end portion connected in a connection direction, a bottom portion, a side portion, a top portion, and a second end portion that is overlapped with the first end portion during packaging, and is characterized in that at least one of the bottom portion and the top portion has a polygonal shape when packaged. Effect of the Invention

[0007] According to the present invention, a packaging material can be provided that can prevent packaged items from tipping over even when the packaging material is formed from sheet material alone and the packaged items are stored in a packaging box. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of packaging material 1. Packaging material 1 is a packaging material that can be used to wrap a packaged item, a pot with handle 80 (see FIGS. 2 and 3), by valley-folding folding lines 20 (first folding line 21 to fifth folding line 25) described below, and can be stored in a packaging box 90 (see FIG. 5) for transportation, etc. In the following description, the surface visible in FIG. 1 is the inner surface when packaged. However, packaging material 1 can also be turned over and the opposite surface used as the inner surface when packaged. In this case, folding lines 20 are mountain-folded.

[0010] Packaging material 1 is formed into a sheet-like shape from cardboard. Packaging material 1 is formed into an elongated shape in the direction in which pot 80 is wrapped (the up-and-down direction in FIG. 1, connection direction D indicated by the arrow). Packaging material 1 has bottom surface portion 15 that becomes the bottom of pot 80 when it is packaged. In addition to bottom surface portion 15, first end portion 11, side surface portion 13, top surface portion 14, and second end portion 12 of packaging material 1 are connected in connection direction D (in other words, the elongated direction).

[0011] The bottom surface portion 15 is formed into a polygonal, substantially octagonal shape when packaged (i.e., when the first fold line 21 and the second fold line 22 are folded in; hereinafter, "when packaged" refers to the state in which at least the first fold line 21 to the fifth fold line 25 are woven in). The bottom surface portion 15 has four inclined edges 15a that face each other at positions inclined at 45 degrees with respect to the connection direction D. Between the inclined edges 15a in the connection direction D, two linear straight edges 15b that are parallel to the connection direction D are formed.

[0012] One end side of the bottom surface portion 15 (the end side on the lower side in FIG. 1) is connected to the first end portion 11 via a first fold line 21. Notches 31 are provided on both ends of the first fold line 21. An easy-releasability hole 30, which will be described later, is provided on the first fold line 21.

[0013] The first end 11 is formed in a generally trapezoid shape with the bottom surface 15 side as the long side when packaged. The folded-in portion 16 is connected to the end side (short side of the generally trapezoid) of the first end 11 via the fifth fold line 25. The folded-in portion 16 has a width generally the same as the long side of the generally trapezoid shape of the first end 11, and an inclined edge 16a is formed with a C-chamfered corner on the first end 11 side. The first end 11 is provided with a handle holding portion 11a formed so as to be able to open like a double door at its approximately center. More specifically, the handle holding portion 11a has two parallel cut portions 11a1 and 11a2 that are long in a direction perpendicular to the connection direction D, and a cut portion 11a3 is formed at the approximately center of the cut portions 11a1 and 11a2 so as to connect them in the connection direction D. The handle holding portion 11a can be opened like a double door from the cutout portion 11a3, with the line connecting the ends of the cutout portions 11a1 and 11a2 being the handle holding folding line 27a.

[0014] Also, near both corners on the bottom surface portion 15 side of the first end portion 11, there are provided cut-out portions 11b1 cut in an inclined line. The cut-out portions 11b1 are cut so that a tongue-shaped portion including the corners of the first end portion 11 becomes gradually narrower from the outside to the inside, and the tongue-shaped portion serves as the locked portion 11b. The base end of the locked portion 11b serves as a locking piece folding line 29a.

[0015] The side surface portion 13 is connected to the other end side (the upper end side in FIG. 1) of the bottom surface portion 15 via a second fold line 22. The side surface portion 13 is formed in a substantially trapezoid shape with the bottom surface portion 15 side as the long side when packaged. The second fold line 22 is provided between the two inclined edges 15a on the other end side. The side surface portion 13 is provided with a handle holding portion 13a formed so as to be able to open like a double door. More specifically, the handle holding portion 13a has two parallel cut portions 13a1 and 13a2 that are long in a direction perpendicular to the connection direction D, and a cut portion 13a3 is formed at the substantially center of the cut portions 13a1 and 13a2 so as to connect them in the connection direction D. As a result, the handle holding portion 13a can be opened like a double door from the cut portion 13a3, with the line connecting the ends of the cut portions 13a1 and 13a2 as the handle holding fold line 27b.

[0016] The top surface portion 14 is connected to the other end of the side surface portion 13 via a third fold line 23. The top surface portion 14 is formed into a polygonal, substantially octagonal shape during packaging. The top surface portion 14 has an inclined edge 14a formed on one of a pair of opposing sides that face each other at an angle of 45 degrees with respect to the connection direction D. The other pair of opposing sides, that is, fold lines 26, are each provided with an entry prevention piece 17 that extends from the fold line 26 in the connection direction D.

[0017] One of the two intrusion prevention pieces 17 (intrusion prevention piece 17-1) is extended toward one end side (first end 11 side) of the packaging material 1, and the other (intrusion prevention piece 17-2) is extended toward the other end side (second end 12 side described later) of the packaging material 1. A notch 32 is provided between the intrusion prevention piece 17-1 extended toward one end side and the side surface portion 13, and between the intrusion prevention piece 17-2 extended toward the other end side and the second end 12. A straight edge 14b parallel to the connection direction D is formed between the inclined edge 14a and the folding line 26. The straight edge 14b is linearly continuous with the outer edge of the intrusion prevention piece 17. In addition, a round hole serving as a lid confirmation hole 14c is formed in the approximate center of the top surface portion 14. The top surface portion 14 equipped with the intrusion prevention piece 17 is formed symmetrically with respect to a point.

[0018] The second end 12 is connected to the other end of the top surface 14 via a fourth fold line 24. The second end 12 is formed in a generally trapezoid shape with the other end side as the long side when packaged. An elongated rectangular opening 12a is provided in the generally central portion of the second end 12 in a direction perpendicular to the connection direction D. In addition, in the vicinity of both corners on the end side of the second end 12, a slanted linear cut line 12b1 is provided. The cut line 12b1 is cut so that the tongue-shaped portion including the corners of the second end 12 gradually narrows, and the tongue-shaped portion is the locking piece 12b. The base end of the locking piece 12b is the locking piece fold line 29b. The edge 12b2 of the locking piece 12b in the direction perpendicular to the connection direction D may be formed so as to be continuous with the generally trapezoid edge line 12c of the second end 12, or the edge 12b2 may be formed so as to protrude.

[0019] In this way, packaging material 1 has multiple fold lines 20 (first fold line 21 to fifth fold line 25) formed in a direction perpendicular to connection direction D. Packaging material 1 is formed by cutting or slitting a single sheet of cardboard. Also, in pot 80 with two handles of this embodiment, the diameter of the bottom is smaller than the diameter of the upper opening, so the area of ​​bottom portion 15 is set smaller than the area of ​​top portion 14.

[0020] As shown in Fig. 2, the packaging material 1 can be used to package a pot 80 as a packaged item and place it in a packaging box 90 (see Fig. 5) for transport or the like. To package the pot 80, first place the pot 80 on the flat surface of the bottom portion 15. At this time, it is recommended that the lid 82, which is made of glass or the same material (enamel, etc.) as the pot body 81, be set upside down on the pot body 81 so that the handle 82a of the lid 82 faces the pot body 81 (inside). The two handles 83 of the pot 80 are arranged along the connection direction D.

[0021] After placing the pot 80 on the bottom surface 15, the fold lines 20 (first fold line 21 to fifth fold line 25) are folded in a valley and the pot 80 is wrapped in the packaging material 1. At this time, as shown in FIG. 3, the handle holding portions 11a, 13a are opened outward so that the handle 83 of the pot 80 protrudes. At this time, the handle 83 of the pot 80 is protected by the handle holding portions 11a, 13a which are opened like a double door. Therefore, the packaging material 1 can compactly package the pot 80 with the handle protruding, while also protecting the protruding handle 83.

[0022] 3, second end 12 is positioned so as to overlap the outside of first end 11. Then, opening 12a of second end 12 matches handle holding portion 11a of first end 11, exposing open handle holding portion 11a and handle 83. Furthermore, when packaging material 1 is wrapped, fold-in portion 16 extending from first end 11 is positioned from the edge of the opening of pot 80 to the upper side of pot 80.

[0023] Furthermore, locking piece 12b of second end 12 is folded in toward the inside of packaging material 1 (pot with two handles 80) and is locked to locked portion 11b. At this time, by folding locking piece 12b, the tongue-shaped portion of locked portion 11b is also folded in along with locking piece 12b. Locking piece 12b is then sandwiched and locked in the space created by the folded tongue-shaped portion of locked portion 11b. Here, the width of the tongue-shaped portion of locking piece 12b is made wider overall than the width of the tongue-shaped portion of locked portion 11b, and this, together with the tapered shape of each tongue-shaped portion, more reliably locks locking piece 12b to locked portion 11b.

[0024] During packaging, as shown in FIG. 4(a) as viewed from the bottom side (direction P in FIG. 3), the easy-release hole 30 is semicircular when viewed from the bottom of the bottom portion 15. Then, as shown in FIG. 4(b), by inserting a finger into the easy-release hole 30, the finger can be hooked on the edge portion 12d of the second end portion 12 corresponding to the easy-release hole 30. Therefore, when unwrapping the packaging material 1, the finger can be inserted into the easy-release hole 30, hooked on the edge portion 12d of the second end portion 12 and pulled outward to separate the locking piece 12b from the locked portion 11b, thereby releasing the locking between the locking piece 12b and the locked portion 11b. Here, the pot body 81 is not shown in FIG. 4(a) and FIG. 4(b).

[0025] Furthermore, even after wrapping with the wrapping material 1 and engaging piece 12b and engaged portion 11b are engaged, it is possible to check through lid confirmation hole 14c whether or not lid 82 has been wrapped together with the main body of pot 80.

[0026] 5 shows two pots 80 packaged in packaging material 1 stored in a packaging box 90. Two opposing inclined edges 14a of top surface 14 abut against the inner surface of the side wall of packaging box 90. Additionally, entry prevention pieces 17 are folded toward bottom surface 15 along inclined fold lines 26, thereby abutting against the inner surface of the side wall of packaging box 90 and entry prevention pieces 17 of adjacent packaged pots 80.

[0027] In this way, even when the pot 80 packaged with the packaging material 1 is stored in a packaging box 90 and transported, one of the sloping edges 14a of the roughly octagonal top surface 14 abuts against the inner wall surface of the packaging box 90, preventing the pot 80 packaged with the packaging material 1 from tipping over during transport, etc. In this embodiment, the sloping edge 14a of the top surface 14 abuts against the inner surface of the packaging box 90, but this is not limited to the above, and the sloping edge 15a of the bottom surface 15 may also abut.

[0028] Although the embodiment of the present invention has been described above, the present invention is not limited to the embodiment, and various modifications can be made. For example, in the present embodiment, the intrusion prevention piece 17 is provided, but the intrusion prevention piece 17 can be omitted, or the packaging material 1 can be provided with only one intrusion prevention piece 17. In this case, it is preferable that the packaging box 90 is capable of storing one packaged two-handled pot 80. In addition, a holding portion is formed in the bottom portion 15, and the intrusion prevention piece 17 can be folded so that its tip is held by the holding portion. In this way, the intrusion prevention piece 17 functions as a support that supports the bottom portion 15 and the top portion 14 so that the gap between them is not crushed. In addition, in the present embodiment, the area of ​​the bottom portion 15 is set smaller than the area of ​​the top portion 14, but for example, in a packaging material for a stockpot, the areas of the bottom portion 15 and the top portion 14 can be made equal, and the area of ​​the bottom portion 15 can also be made larger than the area of ​​the top portion 14, and various shapes can be selected according to the shape of the packaged item. In this embodiment, the top surface 14 and the bottom surface 15 are formed into a substantially octagonal shape when packaged, but they can be formed into other polygonal shapes, such as a substantially hexagonal shape, depending on the shape of the packaging box 90 and the pot 80. In this embodiment, the packaged item is the pot 80, but the present invention can be applied to packaging materials for packaging other cooking utensils and other items. The packaged item can also be packaged in the packaging material 1 so that it is curved without providing all or some of the fold lines 20 (first fold line 21 to fifth fold line 25), but if the fold lines 20 are formed, the packaged item can be packaged more compactly. The packaging material 1 may be made of any material other than cardboard, as long as it is a sheet-like material. [Explanation of symbols]
