Description

This specification discloses technology related to a packaging container that has a support part that supports the packaged item.

Patent Document 1 discloses a packaging box that has inclined pieces that extend from each of two opposing side panels to the bottom panel. The inclined pieces prevent stored items from tipping over.

Japanese Utility Model Application Publication No. 60-33012

The above technology can prevent the packaged item from rolling around significantly inside the packaging container. However, for example, if the packaged item has a shape that makes it prone to rolling, the inclined piece alone may not be enough to stabilize the packaged item.

This specification provides a technology for stabilizing packaged items within a packaging container.

The first aspect disclosed in this specification relates to a packaging container. The packaging container comprises a container body including a bottom plate, a side wall including a first side plate and a second side plate facing each other across the bottom plate and surrounding the bottom plate, and a support part supporting an item to be packaged in the container body, the support part comprising a first support piece extending from the first side plate and a second support piece extending from the second side plate, the first support piece extending from the first side plate toward the second side plate, a first portion approaching the bottom plate as it approaches the second side plate, and a second side of the first portion. and a second portion extending from the edge of the second side plate toward the bottom plate, the second support piece extending from the second side plate toward the first side plate, a third portion approaching the bottom plate as it approaches the first side plate, and a fourth portion extending from the edge of the third portion on the first side plate side toward the bottom plate, and the first portion, the second portion, the third portion, and the fourth portion may have an opening that conforms to the shape of the packaged item placed between the first support piece and the second support piece.

In this configuration, the packaged item is supported by the opening located in the first support piece and the second support piece extending from the opposing first side plate and second side plate, respectively. Because the opening has a shape that conforms to the packaged item, it is possible to prevent the packaged item from shifting out of the state in which it is contained within the opening inside the packaging container. This allows the packaged item to be stabilized inside the packaging container.

In the second aspect, in the first aspect, the distance from the bottom plate to the edge of the first portion on the second side plate side and the distance from the bottom plate to the edge of the third portion on the first side plate side may each be 1/2 or less of the distance between the bottom plate and the part of the packaged item that is furthest from the bottom plate when the packaged item is contained in the packaging container.

In this configuration, the support portion is positioned half or less from the packaged item at the midpoint between the first side plate and the second side plate. Therefore, half or more of the packaged item is exposed from the support portion. With this configuration, when the packaged item is contained in the packaging container and fits into the opening, the portion of the packaged item exposed from the support portion can be increased, making it easier to view the packaged item from the outside when it is contained in the packaging container.

A third aspect is any one of the first and second aspects above, in which the first portion may extend from an upper edge of the first side plate.

With this configuration, it is not necessary to place the first portion at the middle position in the vertical direction of the first side panel. This allows the first portion to be extended from the upper edge of the first side panel toward the second side panel, and the first portion can be produced, for example, by bending the fold line located at the upper edge of the first side panel.

In a fourth aspect, in any one of the first to third aspects, the fourth part may support the packaged item from the bottom plate side at the opening.

With this configuration, the packaged item can be supported from the bottom plate side in a shape that conforms to the packaged item. This allows the packaged item to be supported more stably than when supported by the bottom plate.

In a fifth aspect, in any one of the first to fourth aspects, the first side panel is connected to the bottom panel via a fold line, and can be folded at the fold line from a first state in which the first side panel is located on the same flat plate as the bottom panel to a second state in which the first side panel stands up against the bottom panel, and the second portion is joined to the bottom panel at an end on the bottom panel side, and in the first state, the first portion and the second portion overlap the first side panel and the bottom panel on the same flat plate, and when folded from the first state to the second state, the first support piece may be formed by folding between the first portion and the second portion.

In this configuration, in the first state, the first and second parts are arranged on the same flat plate, and are placed on top of the first side plate and bottom plate, which are also arranged on the same flat plate. This allows the first and second parts, the first side plate, and the bottom plate to be folded flat in the first state. Also, the second state can be easily created by raising the bottom plate relative to the first side plate and folding it between the first and second parts.

In a sixth aspect, in any one of the first to fifth aspects, the first side panel is connected to the bottom panel via a fold line, and can be folded at the fold line from a first state in which the first side panel is on the same flat plate as the bottom panel to a second state in which the first side panel stands up against the bottom panel, and the total length of the length from the edge of the first part on the first side panel side to the edge of the second part on the second side and the length from the edge of the first part on the first side panel side to the edge of the bottom panel side may be equal to the total length of the length from the location where the edge of the first part on the first side panel side of the first side panel is located to the bottom panel, and the length from the edge of the first side panel on the bottom panel side to the edge of the second part on the bottom panel side.

The above-mentioned deployment body for producing the packaging container is also new and useful.

(First embodiment)
As shown in FIG. 1, the packaging container 10 accommodates the packaged item X. The packaging container 10 covers the packaged item X by covering it from above with the lid portion 70 shown in FIG. 6. When the lid portion 70 is open, the packaging container 10 supports the packaged item X in a state where it is exposed to the outside. The packaging container 10 includes the lid portion 70, but in the following, the main box portion not including the lid portion 70 is also referred to as the packaging container 10. The packaging container 10 is used to transport the packaged item X. The packaged item X has a cylindrical shape. The use of the packaging container 10 is not limited to transportation, and may be used for protection, storage, etc. The front-back, left-right, and up-down directions included in this specification are defined for ease of explanation and do not define the posture during actual use.

The packaging container 10 shown in FIG. 1 is in a packaged state. The packaging container 10 includes a container body 11 and a support portion 40. The container body 11 includes a bottom plate 12 and a side wall 13. As shown in FIG. 3, the packaging container 10 is made by folding a plurality of fold lines provided on a single flat plate-shaped deployable body BL1. Each of the plurality of fold lines has at least one of a groove and a slit along the fold line so that the container can be easily folded along the fold line. The plurality of fold lines are represented by thin dashed lines. In addition, the locations where adhesive is applied are represented by thin lines in a lattice pattern. The deployable body BL1 is made of a single sheet of corrugated cardboard. The deployable body BL1 may be made of paper other than corrugated cardboard or resin.

The bottom plate 12 has a rectangular shape. An insert piece 12a is connected to each of the left and right end edges of the bottom plate 12 via a bend line.

In the packaged state, the bottom plate 12 is surrounded by side walls 13. The side walls 13 include four side plates 14, 16, 18, and 18. The side plate 14 is connected to the rear edge of the bottom plate 12 via a fold line. The side plate 14 has a rectangular shape. The left-right length of the side plate 14 is approximately equal to the left-right length of the bottom plate 12. The side plate 18 is connected to each of the left and right ends of the side plate 14 via a fold line.

The length of the side panel 18 in the front-to-rear direction is approximately equal to the length of the bottom panel 12 in the front-to-rear direction. An adhesive piece 18b is connected to the upper edge of the side panel 18 via a fold line. The adhesive piece 18b is folded so as to overlap the side panel 18, and is adhered to the inside surface of the side panel 18 over the entire surface. In FIG. 3, the area where the adhesive is applied is indicated by parallel diagonal lines. The same applies below. An insert piece 18a is connected to the edge of the side panel 18 opposite the side panel 14 via a fold line. The side panels 18, adhesive pieces 18b, and insert pieces 18a at both left and right ends of the side panel 14 have the same configuration.

A first support piece 20 is connected to the edge of the side panel 14 opposite the bottom panel 12. The first support piece 20 includes a first portion 22, a second portion 24, and an adhesive piece 26. The first portion 22 is connected to the side panel 14 via a bend line. The first portion 22 has a rectangular shape. The left-right length of the first portion 22 is approximately equal to the left-right lengths of the bottom panel 12 and the side panel 14. An insertion piece 22a is connected to each of the left-right end edges of the first portion 22 via a bend line.

The second part 24 is connected to the edge of the first part 22 opposite the side panel 14 via a fold line. The second part 24 has a rectangular shape. The left-right length of the second part 24 is approximately equal to the left-right length of the first part 22. The adhesive piece 26 is connected to the edge of the second part 24 opposite the first part 22 via a fold line. The adhesive piece 26 is adhered to the bottom panel 12. The left-right length of the adhesive piece 26 is approximately equal to the left-right length of the second part 24.

The first support piece 20 has three openings 28 spanning the first portion 22 and the second portion 24. Each opening 28 penetrates the first portion 22 and the second portion 24. Each opening 28 has a shape that follows the outer shape of the packaged item X in the packaged state. A pressing piece 28a formed by cutting both left and right end edges from a flat plate to form each opening 28 is connected to the first portion 22 via a fold line. A portion of the adhesive piece 26 includes a portion that is cut from the flat plate that constitutes the second portion 24 to create the opening 28. In other words, a portion of the adhesive piece 26 is positioned beyond the fold line between the adhesive piece 26 and the second portion 24.

The side plate 16 is connected to the front edge of the bottom plate 12 via a fold line. The second support piece 30 is connected to the edge of the side plate 16 opposite the bottom plate 12. The second support piece 30 includes a third portion 32, a fourth portion 34, an adhesive piece 36, and two insert pieces 32a. The side plate 16, the third portion 32, the fourth portion 34, the adhesive piece 36, and the two insert pieces 32a have the same configuration as the side plate 14, the first portion 22, the second portion 24, the adhesive piece 26, and the two insert pieces 22a. However, the shape of the opening 38 arranged in the third portion 32 and the fourth portion 34 is different from the opening 28. This is because the openings 28 and 38 are determined by the shape of the packaged item X. The side plate 16, the third portion 32, the fourth portion 34, the adhesive piece 36, and the two insert pieces 32a are arranged symmetrically with the side plate 14, the first portion 22, the second portion 24, the adhesive piece 26, and the two insert pieces 32a, excluding the opening 38, with respect to a plane parallel to the left and right directions at the center of the front-rear direction of the bottom plate 12. Note that the side plate 18 is not connected to the side plate 16.

Three openings 38 are arranged across the third portion 32 and the fourth portion 34. Each opening 38 penetrates the third portion 32 and the fourth portion 34. Each opening 38 has a shape that follows the outer shape of the packaged item X in the packaged state. A pressing piece 38a formed by cutting both left and right end edges from a flat plate to form each opening 38 is connected to the third portion 32 via a fold line. A part of the adhesive piece 36 is composed of a part that is cut from the flat plate that constitutes the fourth portion 34 to create the opening 38. In other words, a part of the adhesive piece 36 is arranged beyond the fold line between the adhesive piece 36 and the fourth portion 34.

(Packaging container 10 in transport state)
A method of producing the packaging container 10 in the transport state shown in Fig. 4 from the unfolded body BL1 will be described. First, the unfolded body BL1 is folded along the fold line between the side plate 14 and the first support piece 20. As a result, the adhesive piece 26 overlaps the bottom plate 12. The adhesive piece 26 is adhered to the bottom plate 12 over its entire surface. Note that the portion of the adhesive piece 26 that was located within the opening 28 in the unfolded body BL1 does not need to be adhered. Next, the unfolded body BL1 is folded along the fold line between the side plate 16 and the second support piece 30. As a result, the adhesive piece 36 overlaps the adhesive piece 26. An adhesive is applied to the portion of the adhesive piece 36 that overlaps with the adhesive piece 26, and the adhesive piece 36 is adhered to the upper surface of the adhesive piece 26.

The adhesive pieces 18b on both the left and right sides are folded so as to overlap the side plate 18, and are adhered to the inner surface of the side plate 18 over the entire surface. This produces a packaging container 10 in a transport state. In the transport state, the first portion 22, the second portion 24, and the adhesive piece 26 of the first support piece 20 are arranged on the same flat plate, the bottom plate 12 and the side plates 14 and 16 are arranged on the same flat plate, and the third portion 32, the fourth portion 34, and the adhesive piece 36 of the second support piece 30 are arranged on the same flat plate. In the transport state, except for the portion where the bottom plate 12, the adhesive piece 26, and the adhesive piece 36 overlap each other, the first portion 22, the second portion 24, and the adhesive piece 26 on the same flat plate and the bottom plate 12 and the side plate 14 on the same flat plate overlap each other, and the third portion 32, the fourth portion 34, and the adhesive piece 36 on the same flat plate and the bottom plate 12 and the side plate 16 on the same flat plate overlap each other.

As a result, in the transport state, the container is made up of two overlapping flat plates, except for the portion where the bottom plate 12, adhesive piece 26, and adhesive piece 36 overlap each other. The portion where the bottom plate 12, adhesive piece 26, and adhesive piece 36 overlap each other is made up of three overlapping flat plates. With this configuration, the packaging container 10 can be folded flat in the transport state.

In the packaging container 10 in the transport state, the length D1 from the edge of the side panel 14 on the first portion 22 side to the edge of the second portion 24 on the bottom plate 12 side, i.e., the boundary position between the second portion 24 and the adhesive strip 26 (position 12b in FIG. 3), is equal to the length D2 from the edge of the first portion 22 on the side panel 14 side to the edge of the second portion 24 on the bottom plate 12 side. Similarly, the length D1 from the edge of the side panel 16 on the third portion 32 side to the edge of the fourth portion 34 on the bottom plate 12 side, i.e., the boundary position between the fourth portion 34 and the adhesive strip 36 (position 12c in FIG. 3), is equal to the length D2 from the edge of the third portion 32 on the side panel 16 side to the edge of the fourth portion 34 on the bottom plate 12 side.

(Transformation from transport state to packaged state)
1 and 2 in order to accommodate the packaged item X, the side plates 14, 16 are each folded upward and raised with respect to the bottom plate 12, as shown in Fig. 5. At this time, in the first support piece 20, the second portion 24 is folded upward with respect to the adhesive piece 26, and the first portion 22 is folded with respect to the side plate 14 and the second portion 24 so as to extend from the upper end of the second portion 24 to the upper end of the side plate 14, while being spaced from the side plate 14. Similarly, in the second support piece 30, the fourth portion 34 is folded upward with respect to the adhesive piece 36, and the third portion 32 is folded with respect to the side plate 16 and the fourth portion 34 so as to extend from the upper end of the fourth portion 34 to the upper end of the side plate 16, while being spaced from the side plate 16, while being spaced from the side plate 16.

Next, each of the two insert pieces 12a is raised upward relative to the bottom plate 12. Additionally, each of the two insert pieces 22a is bent downward relative to the first portion 22, and each of the two insert pieces 32a is bent downward relative to the third portion 32. Each of the two side plates 18 is bent relative to the side plate 14 and placed at each of the left and right ends of the packaging container 10. The insert pieces 18a are inserted into the packaging container 10 along the inner surface of the side plate 16.

The fourth portion 34 includes a support portion 38b that supports from below the packaged item X placed in the openings 28, 38. This allows the packaged item X to be supported more stably than when the cylindrical packaged item X is supported by abutting against the bottom plate 12.

In addition, the pressing piece 28a presses the packaged item X placed in the openings 28 and 38 forward, and the pressing piece 38a presses the packaged item X placed in the openings 28 and 38 backward, thereby stably supporting the packaged item X.

The first portion 22 is inclined downward from the side plate 14 toward the third portion 32, i.e., toward the center of the packaging container 10 in the front-rear direction. The third portion 32 is also inclined downward from the side plate 16 toward the first portion 22. The portion of the packaged item X arranged in the openings 28, 38 that is furthest from the bottom plate 12, i.e., the distance from the highest point of the packaged item X to the bottom plate 12, is at least twice the distance from the end of the first portion 22 on the second portion 24 side to the bottom plate 12, and is at least twice the distance from the end of the third portion 32 on the fourth portion 34 side to the bottom plate 12. The end of the first portion 22 on the second portion 24 side and the end of the third portion 32 on the fourth portion 34 side are located in the center of the packaging container 10 in the front-rear direction. The highest point of the packaged item X is also located in the center of the packaging container 10 in the front-rear direction. As a result, in the center of the front-to-rear direction of the packaging container 10, more than half of the packaged item X is exposed from the packaging container 10 in the up-down direction. This means that a large portion of the packaged item X is exposed when it is contained in the packaging container 10. As a result, the packaged item X can be confirmed while it is contained in the packaging container 10.

In addition, the side wall 13 is lower than the highest point of the packaged item X. This allows a larger exposed portion of the packaged item X when it is contained in the packaging container 10.

The first support piece 20 extends from the upper edge of the side plate 14. This eliminates the need to position the first support piece 20 in the vertical center of the side plate 14. This allows the first support piece 20 to be connected to the upper edge of the side plate 14 via only a fold line, making it easy to create the first support piece 20 from the deployable body BL1.

As shown in FIG. 7, the lid 70 includes a top plate 78 and side plates 72, 72, 74, and 74. The corners of the side plates 72 and 74 include abutment pieces 76 that abut against the upper edges of the side walls 13 to position the lid 70 in the up-down direction.

Second Example
7 to 10, the packaging container 210 of this embodiment will be described, mainly focusing on the differences from the packaging container 10. As shown in Fig. 7, the packaging container 210 accommodates one packaged item Y. The packaged item Y is, for example, a bottle for a beverage.

The packaging container 210 shown in FIG. 7 is in a packaged state. The packaging container 210 comprises a container body 211 and a support portion 240. The container body 211 comprises a bottom plate 212 similar to the bottom plate 12 and a side wall 213 similar to the side wall 13. As shown in FIG. 9, the packaging container 210 is produced by folding a number of fold lines provided on a single flat, unfoldable body BL2.

An insert piece 212a similar to the insert piece 12a is connected to the bottom plate 212. The side wall 213 has four side plates 214, 216, 218, 218 similar to the four side plates 14, 16, 18, 18. The side plate 218 has an insert piece 218a and an adhesive piece 218b similar to the insert piece 18a and adhesive piece 18b, similar to the side plate 18.

A first support piece 220 is connected to the edge of the side plate 214 opposite the bottom plate 212. The first support piece 220 includes a first portion 222, a second portion 224, and an adhesive piece 226. The first portion 222 is connected to the side plate 214 via a bend line. The first portion 222 has a rectangular shape. The left-right length of the first portion 222 is approximately equal to the left-right lengths of the bottom plate 212 and the side plate 214. An insertion piece 222a is connected to each of the left-right end edges of the first portion 222 via a bend line.

The second part 224 is connected to the edge of the first part 222 opposite the side plate 214 via a fold line. The second part 224 has a rectangular shape. The left-right length of the second part 224 is approximately equal to the left-right length of the first part 222. The adhesive piece 226 is connected to the edge of the second part 224 opposite the first part 222 via a fold line. The adhesive piece 226 is adhered to the bottom plate 212. The left-right length of the adhesive piece 226 is approximately equal to the left-right length of the second part 224. A part of the adhesive piece 226 extends beyond the fold line between the adhesive piece 226 and the second part 224 to the second part 224 side.

The first support piece 220 has one opening 228 spanning the first part 222 and the second part 224, and each opening 228 penetrates both the first part 222 and the second part 224. In the packaged state, the opening 228 has a shape that follows the outer shape of the packaged item Y. In the first part 222, a plurality of pressing pieces 228a are connected to the periphery of the opening 228 via fold lines by making cuts in the flat plate except for the periphery of the opening 228 to form the opening 228.

A second support piece 230 is connected to the edge of the side panel 216 opposite the bottom panel 212. The second support piece 230 includes a third portion 232, a fourth portion 234, an adhesive piece 236, and two insert pieces 232a. The third portion 232, the fourth portion 234, the adhesive piece 236, and the two insert pieces 232a have the same configuration as the first portion 222, the second portion 224, the adhesive piece 226, and the two insert pieces 222a. The shape of the opening 238 arranged in the third portion 232 and the fourth portion 234 is the same as the shape of the opening 228, in accordance with the shape of the packaged item Y.

(Packaging container 10 in transport state)
A method of producing the packaging container 210 in the transport state shown in Fig. 10 from the unfolded body BL2 will be described. Similar to the case of producing the packaging container 10 in the transport state from the unfolded body BL1, folding is performed between the side plate 214 and the first support piece 220, and the adhesive piece 226 is adhered to the bottom plate 212. Next, folding is performed between the side plate 216 and the second support piece 230, and the adhesive piece 236 is adhered to the adhesive piece 226.

The adhesive pieces 218b on both the left and right sides are folded so as to overlap the side panels 218, and are glued to the inside surface of the side panels 18 over their entire surfaces. This creates a packaging container 210 that is folded flat, similar to the packaging container 10 in the transport state.

In the packaging container 210 in the transport state, the length D3 from the edge of the side plate 214 on the first portion 222 side to the edge of the second portion 224 on the bottom plate 212 side, i.e., the boundary position between the second portion 224 and the adhesive strip 226 (position 212b in FIG. 9) is equal to the length D4 from the edge of the first portion 222 on the side plate 214 side to the edge of the second portion 224 on the bottom plate 212 side. Similarly, the length D3 from the edge of the side plate 216 on the third portion 232 side to the edge of the fourth portion 234 on the bottom plate 212 side, i.e., the boundary position between the fourth portion 234 and the adhesive strip 236 (position 212c in FIG. 9) is equal to the length D4 from the edge of the third portion 232 on the side plate 214 side to the edge of the fourth portion 234 on the bottom plate 212 side.

(Transformation from transport state to packaged state)
In order to transform the packaging container 210 from the transport state to the packaged state, similarly to the packaging container 10, each of the side plates 214, 216 is bent upward relative to the bottom plate 212, the second portion 224 is bent upward relative to the adhesive piece 226, and the first portion 222 is bent so as to extend from the upper end of the second portion 224 to the upper end of the side plate 214 relative to the side plate 214 and the second portion 224, and is bent to the outside of the packaging container 210. Similarly, in the second support piece 230, the fourth portion 234 is bent upward relative to the adhesive piece 236, and the third portion 232 is bent so as to extend from the upper end of the fourth portion 234 to the upper end of the side plate 216, and is bent so as to extend from the upper end of the fourth portion 234 to the upper end of the side plate 216, relative to the side plate 216 and the fourth portion 234.

Next, similar to the packaging container 10, the insert pieces 212a, 222a, and 232a are folded, and each of the two side plates 218 is folded relative to the side plate 214 and placed at each of the left and right ends of the packaging container 210. The insert piece 218a is inserted into the packaging container 210 along the inner surface of the side plate 216.

The packaging container 210 can achieve the same effect as the packaging container 10. The fourth part 234 has a support part 238b that supports the packaged item Y placed in the openings 228, 238 from below. Similarly, the second part 224 also has a support part 238b that supports the packaged item Y placed in the openings 228, 238 from below. This allows the packaged item Y to be supported more stably than when the cylindrical packaged item Y is supported by abutting against the bottom plate 212.

The above describes the embodiments of the present invention in detail, but these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and variations of the specific examples given above.

The first support piece 20 and the second support piece 30 do not have to be arranged symmetrically with respect to a plane parallel to the left and right direction at the center of the front-rear direction of the bottom plate 12. For example, the length of the first portion 22 from the side plate 14 may be longer than the length of the third portion 32 from the side plate 16.

At least one of the first support piece 20 and the second support piece 30 may extend below the upper edge of at least one of the side panels 14, 16.

The adhesive piece 36 does not have to be arranged overlapping the adhesive piece 26. For example, the adhesive piece 36 may be directly adhered to the bottom plate 12. Also, the first support piece 20 does not have to be adhered to the bottom plate 12 by the adhesive piece 26. The first support piece 20 only needs to be joined to the bottom plate 12 so that the second portion 24 rotates around the edge on the bottom plate 12 side relative to the bottom plate 12. Similarly, the second support piece 30 only needs to be joined to the bottom plate 12 so that the fourth portion 34 rotates around the edge on the bottom plate 12 side relative to the bottom plate 12.

The technical elements described in this specification or drawings have technical utility either alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. The technologies illustrated in this specification or drawings achieve multiple objectives simultaneously, and achieving any one of those objectives is itself technically useful.
