Description

[Technical Field]

[0001] The present invention relates to a packaging member that packages a product and also protects the product. [Background technology]

[0002] Conventionally, electronic devices and the like have moving parts or other weak parts (vulnerable parts) that protrude forward or have steps. In such cases, it can be difficult to protect the weak parts from damage or breakdown due to vibrations during transportation using normal packaging methods.

[0003] One possible method of protection would be to add spacers to fit into moving parts or to fill gaps, but increasing the number of parts would make packing and unpacking more complicated. Also, protective parts that are only used during transportation are no longer needed after unpacking and are discarded, so the number of parts must be kept to a minimum, even from an environmental perspective.

[0004] Therefore, a method has been proposed for protecting an article having a movable part, a step, etc. from vibration and impact using a single member. For example, Patent Document 1 discloses a protective member that is inserted into a cavity between an upper and lower part of an article during transportation to protect the article from vibration and impact caused by transportation, and that has an upper surface that contacts the upper part and a lower surface that contacts the lower part formed of a sheet material and are approximately parallel. The lower surface is provided with a vertically erected rib that supports the upper surface, and the rib has a protrusion whose tip is located above the upper surface.

[0005] Patent Document 2 discloses an interior packaging device consisting of a packaging body and vertical and horizontal locking bands. The packaging body is formed with vertical and horizontal flaps that support the loaded item. The locking bands are flexible, strip-shaped sheets or films that cross-cover the surface of the loaded item and apply a tightening force to the vertical and horizontal flaps that support the item.

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-195426 [Patent Document 2] Utility model registration No. 3194333 Summary of the Invention [Problem to be solved by the invention]

[0007] The protective member in Patent Document 1 is inserted into the cavity of a product that has a cavity between the top and bottom to protect the upper part of the item from protrusions or steps, but it is not designed to accommodate weak parts in a multi-layer structure. In Patent Document 2, the protective inner case has a structure in which vertical and horizontal lock bands rise from four directions on the bottom surface, but in this case, in order to place the product on the bottom surface, it is necessary to reach beyond the lock bands to the bottom surface, which creates the problem of making packaging difficult for heavy items.

[0008] In view of the above problems, the present invention aims to provide a packaging member that can protect an item to be packed that has a weak part in one direction and that facilitates packaging work, and a packaging material including the same. [Means for solving the problem]

[0009] In order to achieve the above object, a first configuration of the present invention is a packaging member comprising a main body and a cushioning member. The main body has a rectangular bottom surface on which an item to be packaged is placed and side surfaces connected to three sides of the bottom surface via fold lines, and is assembled by folding a single sheet. The cushioning member is arranged along one side of the main body that is not connected to the side surfaces. The cushioning member has a holding structure that holds the side surfaces in an upright position relative to the bottom surface. [Effects of the Invention]

[0010] According to the first configuration of the present invention, a packaged item having a weak portion in one direction can be effectively protected from external impact by a cushioning member arranged along one side where the side portion is not connected. Furthermore, because the side portion is held upright by the cushioning member, assembly of the packaging material and packaging of the packaged item can be performed simultaneously. Furthermore, because the side portions of the main body are raised from three sides and the remaining side is formed of a cushioning member that is a separate member from the main body, an item can be placed on the bottom portion from the side where the side portion is not formed when the main body is unfolded. Therefore, there is no need to stretch out a long distance when placing an item on the bottom portion, improving assembly ease. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of a packaging material 100 including a packaging member 1 according to one embodiment of the present invention. For ease of explanation, the top surface and two side surfaces on the front side of the outer case 2 are omitted from Fig. 1. As shown in Fig. 1, the packaging material 100 includes the packaging member 1, the outer case 2, and support members 3.

[0013] The packaging member 1 is an inner case (product tray) that packages a product (item to be packed) 4. The packaging member 1 also functions as a protective member that protects the product 4. The detailed configuration of the packaging member 1 will be described later.

[0014] The outer case 2 is a rectangular parallelepiped with an open top, and covers the bottom, sides, and top of the packaging member 1 containing the product 4. In this embodiment, an outer case 2 having an integrally formed bottom, side, and top portion is used, but an outer case 2 that can be separated into an outer case main body having a bottom and side portion and a lid that forms the top portion may also be used.

[0015] The support members 3 are arranged in the gaps between the four corners of the outer case 2 and the corners of the packaging material 1, and protect the product 4 from external impact. The support members 3 also have the function of increasing the pressure resistance when the packaging material 100 is stacked. The support members 3 are formed by folding a cardboard sheet into a predetermined shape.

[0016] FIG. 2 is a perspective view showing an example of a product 4 packaged in the packaging member 1 of this embodiment. In this embodiment, a sheet discharge device is exemplified as the product 4. The product 4 has a device main body 41 and sheet discharge trays 42a and 42b. The sheet discharge trays 42a and 42b protrude from one side of the device main body 41 (the front left side in FIG. 2) so as to overlap in the vertical direction. The tip ends of the sheet discharge trays 42a and 42b are capable of swinging up and down.

[0017] Figure 3 is a plan view showing a state in which a product 4 is placed on the bottom surface 11 of the main body 10 of the packaging member 1 of this embodiment. In Figure 3 and Figure 4 described below, cut lines are indicated by solid lines and fold lines are indicated by dashed lines. The packaging member 1 has the main body 10 and first to third cushioning members 17 to 19 (see Figure 4).

[0018] The main body 10 has a bottom surface 11 and first to third side surface portions 12a to 12c. The bottom surface 11 is rectangular and has a product 4 placed thereon. The first and second side surface portions 12a and 12b are connected to two opposing sides of the bottom surface 11 via fold lines. The third side surface portion 12c is connected to the other side of the bottom surface 11 via a fold line.

[0019] First and second flaps 13a and 13b are connected via fold lines to the sides (upper sides when assembled) of first and second side surface portions 12a and 12b opposite bottom surface portion 11. First and second flaps 13a and 13b are formed with first and second cutouts 14a and 14b, respectively.

[0020] Third flap 13c and fourth flap 13d are connected via fold lines to two sides (the right and left sides when assembled) of third side surface portion 12c that are perpendicular to bottom surface portion 11. First insertion piece 14c and second insertion piece 14d are formed on third flap 13c and fourth flap 13d, respectively.

[0021] In addition, a buffer structure forming portion 15 having a plurality of fold lines is formed in the center of the third side surface portion 12c. By folding the buffer structure forming portion 15 along the fold lines into a rectangular tube shape, a buffer structure that protects the product 4 from impact is formed.

[0022] Cushioning member fixing pieces 16a, 16b are connected to the two sides of the bottom surface portion 11 where the first side surface portion 12a and the second side surface portion 12b are connected via folding lines.

[0023] Fig. 4 is a perspective view showing a state in which first to third buffer members 17 to 19 have been arranged around the sheet discharge trays 42a and 42b of the product 4 from the state in Fig. 3. Fig. 5 is a perspective view of the product 4 and first to third buffer members 17 to 19 in Fig. 4. Fig. 6 is a perspective view showing a state in which the second buffer member 18 has been removed from the state in Fig. 5.

[0024] The first and second cushioning members 17 and 18 are each formed by folding a cardboard sheet into a rectangular tube shape. The first and second cushioning members 17 and 18 are arranged along the sides of the sheet discharge trays 42a and 42b to protect the sheet discharge trays 42a and 42b from external impacts. The first and second cushioning members 17 and 18 are also arranged to protrude outward from the device body 41 of the product 4 to protect the device body 41 from external impacts.

[0025] As shown in Fig. 5, first and second engagement portions 17a, 18a are formed at the upper ends of the first and second cushioning members 17, 18, respectively. First and second protrusions 17b, 18b are formed at the side ends (ends in the protruding direction of the sheet discharge trays 42a, 42b) of the first and second cushioning members 17, 18, respectively. Insertion holes 20 are formed in the side surfaces (surfaces facing the first and second side surface portions 12a, 12b) of the first and second cushioning members 17, 18. Note that the insertion holes 20 of the first cushioning member 17 are not shown in Fig. 5.

[0026] As shown in Fig. 6, the third cushioning member 19 is formed by folding a cardboard sheet multiple times (twice in this embodiment) into a U-shape when viewed from the side. The third cushioning member 19 has a first folded portion 19a and a second folded portion 19b. The first folded portion 19a has a convex shape that faces outward from the packaging member 1. The second folded portion 19b is formed adjacent to an upper portion of the first folded portion 19a and has a convex shape that faces inward from the packaging member 1. The second folded portion 19b has a slit 19c formed therein into which the first folded portion 17b and the second folded portion 18b are inserted.

[0027] The following describes the procedure for assembling the packaging member 1. First, as shown in Fig. 3, the product 4 is placed on the bottom surface 11 of the main body 10. More specifically, the product 4 is placed so that the sheet discharge trays 42a, 42b of the product 4 face the side of the bottom surface 11 to which the first side surface 12a to third side surface 12c are not connected.

[0028] Next, as shown in FIGS. 4 to 6, the first to third cushioning members 17 to 19 are arranged around the sheet discharge trays 42a and 42b. More specifically, the first cushioning member 17 and the second cushioning member 18 are arranged on the sides of the sheet discharge trays 42a and 42b of the products 4. Then, the third cushioning member 19 is arranged between the first cushioning member 17 and the second cushioning member 18. As shown in FIG. 6, the first bent portion 19a of the third cushioning member 19 covers the tip end of the sheet discharge tray 42a, and the second bent portion 19b is inserted into the gap between the sheet discharge trays 42a and 42b.

[0029] Thereafter, the first convex portion 17b of the first buffer member 17 and the second convex portion 18b of the second buffer member 18 are inserted into the slit 19c of the third buffer member 19. As a result, the third buffer member 19 is fixed to the first buffer member 17 and the second buffer member 18 in a bridging manner.

[0030] Next, the buffer structure forming portion 15 of the third side surface portion 12c of the main body portion 10 is folded along the fold line to form the buffer structure. Then, the first side surface portion 12a to the third side surface portion 12c are raised vertically from three sides of the bottom surface portion 11. At this time, the third flap 13c and the fourth flap 14d connected to the third side surface portion 12c are folded inward and overlapped with the inside of the first side surface portion 12a and the second side surface portion 12b, respectively. Then, the first insertion piece 14c of the third flap 13c and the second insertion piece 14d of the fourth flap 13d are inserted into the insertion holes 20 of the first buffer member 17 and the second buffer member 18, respectively. This holds the third side surface portion 12c in an upright position.

[0031] Furthermore, the cushioning member fixing pieces 16a and 16b are bent perpendicular to the bottom surface portion 11 and inserted into the insertion holes 20 of the first cushioning member 17 and the second cushioning member 18, respectively, and fixed therein. As a result, the first cushioning member 17 and the second cushioning member 18 are positioned relative to the bottom surface portion 11.

[0032] Finally, first flap 13a connected to first side surface portion 12a and second flap 13b connected to second side surface portion 12b are folded inward. Then, first cutout portion 14a and second cutout portion 14b are engaged with first engagement portion 17a of first cushioning member 17 and second engagement portion 18a of second cushioning member 18, respectively. This holds first side surface portion 12a and second side surface portion 12b in an upright state. First engagement portion 17a, second engagement portion 18a, and insertion hole 20 form a holding structure that holds first side surface portion 12a to third side surface portion 12c in an upright state relative to bottom surface portion 11.

[0033] The packaging member 1 assembled as described above is placed inside the outer case 2, the support member 3 is inserted into the gap between the packaging member 1 and the outer case 2, and then the outer case 2 is sealed to package the product 4 using the packaging material 100.

[0034] In the packaging member 1 of this embodiment, the first to third side surface portions 12a to 12c face each other in three directions excluding the direction in which the sheet discharge trays 42a and 42b of the product 4 protrude, and the first to third cushioning members 17 to 19 are arranged in the direction in which the sheet discharge trays 42a and 42b protrude. The first cushioning member 17 and the second cushioning member 18 also have first engagement portions 17a and second engagement portions 18a, and insertion holes 20, which hold the first to third side surface portions 12a to 12c upright relative to the bottom surface portion 11.

[0035] This prevents damage to the sheet discharge trays 42a, 42b, which are vulnerable to vibrations and shocks in the vertical direction, because they are held by the first bent portion 19a and the second bent portion 19b of the third buffer member 19. In other words, the product 4, which has a weak portion (sheet discharge trays 42a, 42b) with a multi-layer structure in one direction, can be effectively protected from external shocks.

[0036] Furthermore, the packaging member 1 has the first side surface portion 12a to the third side surface portion 12c of the main body portion 10 raised from three directions, and the remaining side surface is formed of a member (first cushioning member 17 to third cushioning member 19) separate from the main body portion 10. This allows the product 4 to be placed on the bottom surface portion 11 from a direction where the first side surface portion 12a to the third side surface portion 12c are not formed, when the main body portion 10 is unfolded. Therefore, there is no need to stretch one's hand far when placing the product 4 on the bottom surface portion 11, improving ease of assembly.

[0037] Furthermore, by arranging the first buffer member 17 and the second buffer member 18 so that they protrude outward from the device body 41 of the product 4 and providing a buffer structure forming portion 15 on the third side portion 12c, the product 4 can be effectively protected from external impacts in three directions other than the protruding direction of the sheet discharge trays 42a and 42b.

[0038] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention. For example, in the above-described embodiment, the third buffer member 19 is folded twice into a U-shape in side view to form the first folded portion 19a and the second folded portion 19b, but by changing the number of folds, the present invention can be applied to products 4 having a fragile portion with a one-layer structure or a three-layer or more structure.

[0039] In addition, in the above embodiment, a sheet discharge device was exemplified as an example of a product 4 packaged by the packaging material 1, but the packaging material 1 of the present invention can be equally applied to products 4 that have a weak portion in one direction other than a sheet discharge device.

[0040] In the above embodiment, the packaging material 100 is described as including the packaging member 1, the outer case 2, and the support member 3, but the packaging material 100 may include other components. For example, a buffer member may be disposed between the upper surface of the packaging member 1 and the top surface of the outer case 2. [Industrial Applicability]

[0041] The present invention can be used for a packaging member that can protect a product while also packaging the product. By using the present invention, it is possible to provide a packaging member that can protect an object to be packaged that has a weak part in one direction and that makes packaging easy, and a packaging material including the same.
