Description

[Technical Field]

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

[0002] In the past, when packaging items in a packaging box, it was common to place packaging material between the items and the inner wall of the packaging box in order to cushion the items from external shocks during transport and to prevent the items from moving up, down, left, or right within the box. Such packaging material was often made by filling the box with many small pieces of polystyrene foam or by forming corrugated cardboard or the like into a specific shape in advance. Summary of the Invention [Problem to be solved by the invention]

[0003] However, when small pieces of packing material are used, a large amount of packing material is required to fill the gaps, resulting in a large amount of waste. Also, when using formed corrugated cardboard as packing material, it is necessary to cut it to the appropriate size each time in order to store various items other than the originally planned shape and size, which is time-consuming and inconvenient for accommodating a wide variety of stored items.

[0004] An object of the present invention is to provide a packaging box that forms an appropriate space between the contained article and the inner surface of the packaging box and that can accommodate contained articles of a wide variety of shapes and sizes. [Means for solving the problem]

[0005] The packaging box according to the present invention comprises a container, a sheet for covering an item to be stored in the container, and a plate-shaped fixing member for pressing and holding the item via the sheet. The sheet includes a first belt-shaped sheet extending in a first direction and a second belt-shaped sheet adhesively fixed to the first sheet while stretching in a direction intersecting the first direction. The fixing member has a first band, a second band, and a third band disposed between the first and second bands. The first and second bands are fixed to and supported by an inner wall surface of the container. The third band is stored in a concave shape in the container. When the item is stored, a portion of the third band is bent and protrudes to become convex, and a top region of the inverted convex shape presses and holds the item via the sheet.

[0006] In the packaging box of the present invention, the sheet used as packaging material covers the stored items, thereby forming an appropriate space between the stored items and the inner surface of the container, and when the stored items are stored, a part of the third band portion of the fixing member folds, protrudes, and turns over into a convex shape, and the top area of ​​the turned over convex shape presses and holds the stored items through the sheet, so that a packaging box can be provided that can accommodate stored items of a wide variety of shapes and sizes and can be transported safely.

[0007] Furthermore, in the packaging box according to the present invention, the third band portion of the fixing member may be divided into a plurality of bands in the vertical direction by a notch extending in the extension direction of the fixing member, and each of the divided bands may be folded and protruded according to the shape of the stored item, and inverted into a convex shape, and the top region of the inverted convex shape may be configured to press and hold the stored item through the sheet.

[0008] In addition, in the packaging box according to the present invention, at least one of the plurality of vertically divided bands is configured to be positioned above the top of the article to be stored, and The bottom surface of the belt, which is positioned above the top of the stored item, may be configured to press and hold the stored item via the sheet.

[0009] In addition, in the packaging box of the present invention, the fixing member may be attached to the container so that when the stored item is stored in the container, the bottom surface of the fixing member is positioned higher than the top of the stored item, and the bottom surface of the band may be configured to press and hold the stored item via the sheet. [Effects of the Invention]

[0010] According to the present invention, the sheet used as packaging material covers the stored items, thereby forming an appropriate space between the stored items and the inner surface of the container, and when the stored items are stored, a part of the third band portion of the fixing member folds, protrudes, and turns convex, and the top area of ​​the turned convex shape presses and holds the stored items through the sheet, thereby providing a packaging box that can accommodate stored items of various sizes and can be transported safely.

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. However, this embodiment is merely an example, and the present invention is not limited to this embodiment.

[0013] Fig. 1 is a schematic perspective view of a packaging box 1 according to this embodiment. Fig. 2 is a diagram showing the vertical arrangement of the components that make up the packaging box 1 and the relationship between the components. Fig. 2 shows each component in a state before it is stored and fixed in the packaging box 1.

[0014] Referring to FIG. 1, packaging box 1 may include a first sheet 2 that holds items in the longitudinal (left-right) direction within container 4, a second sheet 3 that holds items in the lateral (front-to-back) direction within container 4, container 4, which is a box made of a material such as cardboard, and a fastening member 5 that holds items in the vertical direction within container 4 through the sheet. First sheet 2 extends in the longitudinal direction of container 4 and has a first region 6, a second region 7, and a third region 8 that connects first region 6 and second region 7. Second sheet 3 extends in the lateral direction of container 4 and has a fourth region 9, a fifth region 10, and a sixth region 11 that connects sixth region 6 and second region 7. In FIG. 1, first sheet 2 and second sheet 3 are folded against the bottom of container 4, and first sheet 2 is folded behind second sheet 3. The lid of container 4 is not shown in each figure. 2, 5, 9, 10, and 16, the thicknesses of the container 4 and the fixing member 5 are omitted.

[0015] FIG. 2 is a perspective view of the packaging box 1 according to the first embodiment, disassembled into individual components. The third region 8 of the first sheet 2 is elongated and straight in the width direction of the container 4, and is fixed to the second sheet 3 at its bottom by adhesive or other means. The sixth region 11 of the second sheet 3 is elongated and straight in the length direction of the container 4, and is fixed to the bottom of the container 4 at its bottom by adhesive or other means. The third region 8, which is the fixed portion between the first sheet 2 and the second sheet 3, has a width in a first direction in which the first sheet 2 extends (the left-right direction in the example of FIG. 2) that is smaller than the width of the second sheet 3 in the left-right direction and is also smaller than the length of the container 4 in its longitudinal direction (the left-right direction). The sixth region 11, which is the fixed portion between the second sheet and the container, has a width in a second direction in which the second sheet 3 extends (the front-to-rear direction in the example of FIG. 2) that is smaller than the width of the first sheet 2 in the front-to-rear direction and is also smaller than the length of the container 4 in its short direction (the front-to-rear direction). Fixing members 5 are arranged alternately at two opposing corners along the inner surface of the vertical wall of container 4, and are fixed to the side of container 4 by a first band portion 13 and a second band portion 14 using adhesive or other methods. Fixing members 5 are bent or folded so as to be concave when viewed from the stored item 16.

[0016] The first sheet 2 can be bent or folded freely within the range of the first region 6 and the second region 7 on the left and right of the third region 8, because the third region 8 is elongated and linearly shaped (Fig. 3). The second sheet 3 can also be bent or folded freely together with the first sheet 2 within the range of the fourth region 9 and the fifth region 10 on the front and rear of the sixth region 11, because the sixth region 11 is elongated and linearly shaped (Fig. 4).

[0017] FIG. 5 is a diagram of the packaging box 1 when the first sheet 2 and second sheet 3 folded onto the bottom are unfolded. The third region 8 of the first sheet 2 is arranged in a long, straight line near the center of the first sheet 2, with spaces for the first region 6 and the second region 7 from the edge of the bottom of the container 4. This allows the first sheet 2 to be bent or folded freely at any position within the range of the first region 6 and the second region inside the container 4. The sixth region 11 of the second sheet 3 is arranged in a long, straight line near the center of the second sheet 3, with spaces for the third region 9 and the fourth region 10 from the edge of the bottom of the container 4. This allows the second sheet 3 to be bent freely together with the first sheet 2 at any position within the range of the fourth region 9 and the fifth region 10 inside the container 4. Gaps (not shown) are formed between the first region 6 and the second region 7 of the first sheet 2 and the second sheet 3 and the container 4, and between the fourth region 9 and the fifth region 10 of the second sheet 3 and the first sheet 2 and the container 4.

[0018] The first sheet 2 and the second sheet 3 are made of a material that is easy to fold and has a certain tensile strength. Typically, it is kraft paper, but nonwoven fabric, polyethylene film, polyvinyl chloride resin film, rolled cardboard, etc. are also acceptable. The first sheet 2 and the second sheet 3 are preferably made of a material that can be neatly folded and that generates a lot of friction when the sheets come into contact with each other.

[0019] FIG. 6 is a perspective view of the fixing member 5. The fixing member 5 is made of a resilient material such as cardboard and has a notch 12 and first and second bands 13 and 14. The fixing member 5 is fixed to the corners of the container 4 by adhesive or other methods at the first and second bands 13 and 14. The portions of the separated bands separated by the notches 12 other than the first and second bands 13 and 14 form the third bands 15. Because the third bands 15 have the notches 12 in a stepped manner, the bottom surface of the lower part of any of the bands can be positioned above the side of the stored item 16, allowing the bottom surface of the lower part of any of the third bands 15 to press and fix the stored item 16 via the sheet. If the third bands 15 do not have a notch 12 and have only one band, it is desirable to install the fixing member 5 above the top of the container 4 so that the bottom surface of the lower part of the band is positioned above the side of the stored item 16.

[0020] The fixing member 5 is folded and fixed to the corners of the container 4 along the inner side surface of the container 4 by a first band portion 13 and a second band portion 14 using adhesive or other methods (FIG. 9). The fixing member 5 is installed in the corner of the container 4 in a folded, concave state, with a third band portion 15 being the only portion that is not fixed by adhesive or other methods other than the first band portion 13 and the second band portion 14.

[0021] Since the fixing member 5 is provided on the side of the container 4 in a concave state when viewed from the stored item 16, the length of the band of the third band portion 15 is longer than the straight-line distance between the boundary between the first band portion 13 and the third band portion 15 and the boundary between the second band portion 14 and the third band portion 15. Therefore, the fixing member 5 can fold any part of the third band portion 15, pulling out and inverting all or part of the band of the third band portion 15 from its concave state to make it convex, and the convex shape is maintained by tension.

[0022] 7 is a diagram showing the state in which the concave portion of the third band portion 15 of the fixing member 5 has been pulled out and inverted to form a convex shape. The dotted line portion indicates the length of the third band portion 15 when the fixing member 5 is in the concave state, and this length is longer than the linear distance between the boundary between the first band portion 13 and the third band portion 15 and the boundary between the second band portion 14 and the third band portion 15. Therefore, the fixing member 5 can fold all or part of the band portion of the third band portion 15, pulling out the concave state and inverting it to form a convex state.

[0023] The fixing member 5 has the first band portion 13 and the second band portion 14 fixed to the container 4, and since the fixing member 5 is made of an elastic material such as cardboard, when the stored item 16 is pressed and fixed through the first sheet 2 and the second sheet 3, distortion occurs in the bottom surface of the lower part of the band of the band portion 15 that comes into contact with the stored item 16 through the sheets, and stress (elastic force) is generated in the direction of distortion (downward) in the fixing member 5, allowing the stored item 16 to be elastically held and fixed.

[0024] FIG. 8 shows the state in which the concave portion of the third strap portion 15 of the fixing member 5 is pulled out and inverted to make it convex, and the stored item 16 is elastically pressed and fixed via the sheet 3. FIG. 8 shows the state in which the stored item 16 (not shown), which is wrapped by the sheet 3 and the sheet 2 inside it, is pressed and fixed by the second strap from the top and the first strap from the top of the strap portion 15 via the sheet. The second strap from the top of the strap portion 15 is in contact with the stored item 16 via the sheet at its bottom surface. The fixing member 5 is configured such that the first strap portion 13 and the second strap portion 14 are attached to the container 4 (not shown). Since the fixing member 5 is fixed to the wall of the container, the bottom surface of the container 4 and the bottom surface of the lower part of the band of the band part 15 sandwich the stored item 16 through the sheet, and since the fixing member 5 is made of an elastic material such as cardboard, distortion occurs at the bottom surface of the lower part of the band of the band part 15, so stress (elastic force) is generated in the direction of distortion (downward) in the fixing member 5, elastically holding and fixing the stored item 16. In Figure 8, the bottom surface of the first band from the top presses against the top surface of the second band from the top, assisting in the pressing.

[0025] Furthermore, the fixing member 5 is in an elastically distorted state due to being stored in a concave shape in the container 4, and since the fixing member 5 is made of an elastic material such as cardboard, when the concave state is pulled out and inverted to a convex state, elasticity is generated in the fixing member 5 in the distortion direction (front-back and left-right directions) against the stored item 16, and the stored item 16 can be elastically held and fixed.

[0026] The fixing members 5 may be provided at the left rear and right front positions of the container 4 (Fig. 9) or at the left front and right rear. The fixing members 5 may also be provided facing in the same direction, such as at the left rear and right rear (Fig. 10) or at the left front and right front. The fixing members 5 may also be provided at the four corners of the box, front, back, left and right. The vertical positional relationship between the first sheet 2 and the second sheet 3 may be reversed.

[0027] <How to pack box 1> The user unfolds the folded first sheet 2 and second sheet 3 of the packaging box 1, places the item 16 (for example, an ellipsoid) on the first sheet 2 near the center of the container 4 as shown in Figure 11, and folds either the left or right surface of the first sheet 2 near the side of the item 16 (the longitudinal edge of the item 16). Next, the user folds either the left or right surface of the first sheet 2 near the side of the item 16 (the longitudinal edge of the item 16). This fixes the item 16 in the longitudinal direction of the container 4 (Figure 13).

[0028] Next, as shown in Figure 7, the user folds either the front or back of the now cylindrical first sheet 2 near the side of the item 16 to be stored (the short-side edge of the item 16), and then folds the second sheet 3 together with the first sheet 2. Next, the user folds either the front or back of the now cylindrical first sheet 2 near the side of the item 16 to be stored (the short-side edge of the item 16), and then folds the second sheet 3 together with the first sheet 2. This fixes the short-side direction of the container 4 for the item 16 to be stored (Figure 13).

[0029] When the first sheet 2 and the second sheet 3 are positioned such that the second sheet 3 is on top, the user folds the sheets in the short direction of the container 4 and then in the long direction of the container 4.

[0030] Next, the user adjusts the height of the stored item 16 by pulling out the appropriate portion of the third band portion 15, as shown in Figure 14, and sequentially pulls out all or part of the appropriate bands of the third band portion 15 so that the third band portion 15 comes into contact with the second sheet 3, changing the concave state of the third band portion 15 to a convex state. (In Figure 14, only the first and second bands from the top are shown.)

[0031] Figure 15 is a schematic diagram of a packaging box viewed from the front, in which the strap portion has been pulled out and inverted to make the concave corners of the strap portion convex so that it contacts the second sheet covering the stored item. As shown in Figure 15, the bottom surfaces of the first and second straps from the top of the third strap portion 15 apply pressure to the stored item 16 from above via the second sheet 3 and the first sheet 2 therein, thereby holding the stored item 16. The bottom surfaces of the third, fourth, and fifth straps from the top of the third strap portion 15 apply pressure to the second sheet 3 and the first sheet 2 therein, thereby indirectly holding the stored item 16. In this way, the stored item 16 is fixed vertically within the storage box by the folding of the sheets, friction between the sheets, and the stress and elasticity of the third strap portion 15, which has been inverted to form a convex shape by the fixing member 5.

[0032] Each band of the third band portion 15 simultaneously elastically holds the stored item 16 in the front, back, left, and right directions via the sheet from the side. The third band portions 15 located above the third band portion 15 in contact with the second sheet 3 may be overlapped and convex to prevent the third band portion 15 in contact with the second sheet 3 from bending upward. The user then closes the lid of the container 4.

[0033] There is an appropriate space between the first sheet 2 and second sheet 3 covering the stored item 16 and the container 4, and the fixing member 5 holds the stored item 16 through the sheets with stress and elasticity, so that external impacts are absorbed and the stored item can be held in a way that prevents it from moving back and forth, left and right, up and down inside the packaging box.

[0034] By providing multiple notches 12 in the fixing member 5, multiple bands of the third band portion 15 can be provided. In this case, the directions of the inverted tops of each band are different, which distributes the direction of strain and pressure and distributes stress, thereby achieving the same effect as when multiple cushioning materials are used, and ensuring the strength of the packaging box.

[0035] The first and second sheets 2 and 3 of the packaging box 1 are arranged in a cross direction, and the bottoms of the first and second sheets 2 and 3 and the container 4 are fixed in the elongated, straight-line third and sixth regions 8 and 11, respectively, so that the first and second sheets 2 and 3 can be folded or bent at any position within the first, second, fourth, and fifth regions to fit the stored items 16. The fixing member 5 can also be provided with one or more notches 12 to provide multiple third band portions 15 in stages, allowing the third band portions 15 to be selected to fit the vertical height of the stored items 16, and any number of the stored items 16 can be pulled out and inverted. The packaging box 1 can therefore secure and hold stored items 16 of a wide variety of shapes and sizes in all directions, front to back, left to right, top to bottom.

[0036] Although the embodiments of the present invention have been described above, the packaging box of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, the container 4 may be a rectangular parallelepiped, a cube, or other shapes such as a cylindrical shape (FIG. 16). Furthermore, the dimensions and dimensional ratios of each part of the container, first and second sheets, and fixing member are not particularly limited. Furthermore, the materials of the container and fixing member are not particularly limited, and may be cardboard other than cardboard, various types of resin cardboard, or resin board.

[0037] Furthermore, the actions and effects shown in the above-described embodiments are merely a list of the most preferable actions and effects resulting from the present invention, and the actions and effects of the present invention are not limited to these. [Explanation of symbols]
