Description

[Technical field]

[0001] The present disclosure relates to a packaging container and a mobile object. [Background technology]

[0002] Conventionally, technologies related to reinforcing members have been known. For example, Patent Document 1 discloses a box-shaped simple external reinforcing metal fitting that supports the bracing reinforcement and wall reinforcement of the conventional post-and-beam construction method by fixing and holding the foundation and the pillar with a strong L-shaped and inverted T-shaped metal fitting with a box cross section, and prevents the pillar and the foundation from collapsing.

[0003] In addition, packaging containers that store and protect objects are known. For example, a technology related to logistics is known in which a delivery item is stored in such a packaging container and delivered by a moving object such as an aircraft carrying the packaging container. For example, Patent Document 2 discloses a packaging box that allows heavier objects to be transported by an airborne transport object.

[0004] In general, packaging containers are desired to have improved properties such as shock absorption, strength, heat insulation, and light weight. For example, packaging containers used to store deliveries when the deliveries are delivered by a moving object are required to have shock absorption and strength to protect the deliveries from vibrations caused by the movement of the moving object. When protecting medicines, fresh foods, and the like, the packaging containers are also required to have heat insulation properties to maintain the heat insulation effect during transportation. The packaging containers are also required to be light enough to be easily transported by aircraft such as drones. [Prior art documents] [Patent documents]

[0006] However, plastic cardboard, which is commonly used as a packaging container, has low impact absorption and heat insulation. Polystyrene foam, which is also used as a packaging container, is weak against surface abrasion and has low strength. Therefore, it is desired to improve the quality of the packaging container by improving as many of the above-mentioned properties of the packaging container at the same time. In neither of the conventional techniques described in Patent Documents 1 and 2, the improvement of the quality of the packaging container was sufficiently considered.

[0007] The present disclosure aims to provide a packaging container and a moving body that can improve the quality of the packaging container. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] An embodiment of the present disclosure will be mainly described below with reference to the accompanying drawings.

[0013] (First embodiment) Fig. 1 is an external perspective view showing a packaging container 1 according to a first embodiment of the present disclosure in a closed state. Fig. 2 is an external perspective view showing the packaging container 1 of Fig. 1 in an open state. The configuration and function of the packaging container 1 according to the first embodiment will be mainly described with reference to Figs. 1 and 2.

[0014] The packaging container 1 includes a container that holds and protects an object therein. In this disclosure, the "object" includes a delivery item that is delivered by transporting the packaging container 1 using a moving body, as well as any other item different from the delivery item that is protected while the packaging container 1 is being transported, and any item that is protected without the transportation of the packaging container 1. The packaging container 1 has a box body 10 and a reinforcing member 20.

[0015] The box 10 contains a foamable resin and contains an object. The box 10 is formed, for example, from polystyrene foam as a whole. The box 10 has a main body 11 and a lid 12. The box 10 realizes a closed state of the packaging container 1 by fitting the main body 11 and the lid 12 to each other. The box 10 realizes an open state of the packaging container 1 by tilting the lid 12 relative to the main body 11 or shifting the position of the lid 12. The box 10 may be configured such that the main body 11 and the lid 12 are separate parts and are separated from each other when the packaging container 1 is open. The box 10 may be configured such that the main body 11 and the lid 12 are indirectly connected to each other by a connecting part such as a hinge attached to the reinforcing member 20, and the indirect connection between them is maintained even when the packaging container 1 is open.

[0016] The reinforcing member 20 contains a resin and is attached to the box body 10 so as to cover at least a part of the outer surface of the box body 10. The reinforcing member 20 is formed, for example, entirely from a resin. In the present disclosure, "resin" includes hard resins such as thermoplastic resins or cured products of thermosetting resins. More specifically, examples of the resin include polyolefin resins such as polyethylene (PE) and polypropylene (PP); polyamide (PA) resin; rubber-based resins such as acrylonitrile butadiene styrene (ABS) resin, ASA resin, and acrylonitrile / ethylene propylene diene / styrene (AES) resin; aromatic polyester resins such as polycarbonate (PC) resin, polyethylene terephthalate (PET) resin, and polybutylene terephthalate (PBT) resin; polylactic acid (PLA); polyacetal (POM) resin; and polyphenylene sulfide (PPS). Preferred are materials containing one or more thermoplastic resins selected from the group consisting of arylene sulfide (PAS) resins; polyarylene ether resins such as polyether ether ketone (PEEK) resins, and polystyrene (PS) resins, or FRP (fiber-reinforced resin materials such as prepregs, SMCs, or stampable sheets, which are reinforced by impregnating fibers such as glass, carbon fibers, or aramid fibers with the above-mentioned thermoplastic resins, or with thermosetting resins including epoxy resins or vinyl ester resins as a matrix resin and solidifying or curing the impregnated fibers, or molded articles thereof).

[0017] The reinforcing member 20 is integrally attached to the box body 10 by integral molding. In the present disclosure, "integral molding" includes insert molding and the like. The reinforcing member 20 has a first reinforcing member 21 integrally attached to the main body 11 of the box body 10 and a second reinforcing member 22 integrally attached to the lid 12 of the box body 10. When the main body 11 and the lid 12 are fitted together to realize the closed state of the packaging container 1, the first reinforcing member 21 and the second reinforcing member 22 cover the entire edge of the box body 10 from the outside to reinforce the box body 10. At this time, the reinforcing member 20 is attached to the box body 10 so as to have a step toward the outside with respect to the outer surface of the box body 10.

[0018] In this disclosure, "outside" corresponds to the direction toward the opposite side from the center of the packaging container 1. For example, the outside in the direction connecting the lid portion 12 and the bottom wall of the main body portion 11 corresponds to the direction toward the opposite side from the center of the packaging container 1 in that direction. Without being limited to this, the outside does not have to be the direction completely toward the opposite side from the center in that direction, and may correspond to a direction toward the opposite side from the center along a slight diagonal. The same applies to other directions. "Inside" is the opposite of outside.

[0019] When the packaging container 1 is placed on a loading platform or the like, the reinforcing member 20 holds the box body 10 with the bottom wall of the main body 11 located opposite the lid 12 raised above the floor surface of the loading platform. When the packaging container 1 is placed on a loading platform or the like, it maintains its placed state with the bottom wall of the main body 11 of the box body 10 spaced apart from the floor surface of the loading platform. When the packaging container 1 is placed on a loading platform or the like, it maintains its placed state with only the reinforcing member 20 in contact with the floor surface of the loading platform, without the bottom wall of the main body 11 of the box body 10 contacting the floor surface of the loading platform.

[0020] The reinforcing member 20 may be configured such that when the main body 11 and the lid 12 of the box 10 are separate parts, the first reinforcing member 21 and the second reinforcing member 22 are separated from each other when the packaging container 1 is in an open state. The reinforcing member 20 may be configured such that the first reinforcing member 21 and the second reinforcing member 22 are directly connected to each other by a connecting part such as a hinge, and maintain the direct connection to each other even when the packaging container 1 is in an open state.

[0021] The flexural modulus of the resin contained in the reinforcing member 20 is higher than the flexural modulus of the foamable resin contained in the box body 10. The flexural modulus of the resin contained in the reinforcing member 20 is, for example, preferably 800 MPa or more, more preferably 1500 MPa or more. On the other hand, the upper limit is not limited, but may be, for example, 400 GPa or less. The flexural modulus complies with ISO178.

[0022] The packaging container 1 is formed by the following manufacturing method using integral molding.

[0023] The manufacturing method includes a first step of molding a reinforcing member 20 that will become the outer wall of the packaging container 1 by injection molding using a resin. The manufacturing method includes a second step of placing an intermediate body molded in the first step inside a mold used to mold a box body 10 using a foamable resin. The manufacturing method includes a third step of injecting a foamable resin into the intermediate body placed inside the mold in the second step to integrate the intermediate body and the foamable resin.

[0024] In the packaging container 1 as a molded product manufactured based on the manufacturing method as described above, the box body 10 is integrally formed with the reinforcing member 20 by integral molding inside the reinforcing member 20. The reinforcing member 20 forms an outer wall of the packaging container 1.

[0025] In the packaging container 1 according to the first embodiment, the reinforcing member 20 is formed on a portion of the surface of the box body 10. For example, the first reinforcing member 21 of the reinforcing member 20 is formed on each of the outer surfaces of the main body 11 of the box body 10 so as to cover the four corner sides of the outer surface. The first reinforcing member 21 exposes to the outside a wide portion of the outer surface surrounded by the four corner sides.

[0026] The packaging container 1 as a molded product has a two-layer structure based on a box body 10 and a reinforcing member 20. The thickness of the reinforcing member 20 forming the outer first layer is preferably, for example, 0.5 mm or more, and more preferably 1 mm or more. On the other hand, the upper limit is not limited, but may be, for example, 10 mm or less. The thickness of the box body 10 forming the second layer disposed on the inside of the first layer is preferably, for example, 8 mm or more, and more preferably 10 mm or more. On the other hand, the upper limit is not limited, but may be, for example, 100 mm or less.

[0027] In the packaging container 1 as a molded product, the total length of the sides of the length, width and height is not particularly limited, but is preferably 260 cm or less, more preferably 200 cm or less, more preferably 160 cm or less, more preferably 140 cm or less, more preferably 120 cm or less, more preferably 100 cm or less, and even more preferably 80 cm or less. On the other hand, the lower limit is not limited, but is preferably 20 cm or more, and more preferably 40 cm or more.

Fig. 4 is a cross-sectional view taken along the arrow line IV-IV of Fig. 2. Fig. 5 is an external perspective view showing an exploded view of the lid 12 and the second reinforcing member 22 of Fig. 1.

[0029] In reality, the box body 10 and the reinforcing member 20 are integrally molded together, but for ease of understanding, the box body 10 and the reinforcing member 20 are virtually separated and shown as separate units in Figures 3 and 5. Accordingly, for example, the first edge 116 of the box body 10, which will be described later, is given such names and symbols for the sake of convenience, but it should be noted that in these components, the box body 10 and the reinforcing member 20 are actually integrally molded together, and are not inherent components of the box body 10.

[0030] In reality, the first rib 213 and the second rib 223 described below are sandwiched between the foamable resin that forms the box body 10, and gaps are formed in the box body 10 in which these ribs are arranged, but in Figures 3 and 5, the illustration of such gaps is omitted for ease of understanding.

[0054] The reinforcing member 20 has an attachment portion 23 that is attached to the flying object as the moving object 100 when the flying object carries the packaging container 1. In a first example shown in FIG. 7, the attachment portion 23 is formed on the first side portion 212 of the first reinforcing member 21 attached to the main body portion 11. For example, as also shown in FIG. 3, the attachment portion 23 is formed on the center portion of the first side portion 212 that covers the first edge 116 of the main body portion 11. For example, the attachment portion 23 is formed on each of a pair of first side portions 212 that face each other. The attachment portion 23 is formed as a part of the first reinforcing member 21 in the form of a hook structure that protrudes outward from the outer surface of the first side portion 212 in the center portion of the first side portion 212 in a rectangular frame shape.

[0055] 7, the movable body 100 transports the packaging container 1 by hooking a claw portion 110 formed at the tip of the arm of the movable body 100 onto an attachment portion 23 formed on a first reinforcing member 21 of the packaging container 1. The claw portion 110 of the movable body 100 and the attachment portion 23 formed on the first reinforcing member 21 of the packaging container 1 engage with each other, whereby the packaging container 1 is attached to the movable body 100 via the attachment portion 23.

[0056] FIG. 8 is a schematic diagram showing a second example of the use of the packaging container 1 according to the first embodiment of the present disclosure.

[0057] In a second example shown in Fig. 8, the attachment portion 23 is formed on the second side portion 225 of the second reinforcing member 22 attached to the lid portion 12. For example, as also shown in Fig. 6, the attachment portion 23 is formed at a third intersection P3 of a pair of second side portions 225 that face the outer surface 124a of the lid portion 12 along a pair of diagonals of the outer surface 124a of the lid portion 12. The attachment portion 23 is formed as a part of the second reinforcing member 22 with a hook structure that protrudes outward in a ring shape from the outer surface of the second side portions 225 at the third intersection P3.

[0058] 8, the movable body 100 transports the packaging container 1 by hooking a hook portion 120 extending downward from the main body of the movable body 100 onto an attachment portion 23 formed on the second reinforcing member 22 of the packaging container 1. The hook portion 120 of the movable body 100 and the attachment portion 23 formed on the second reinforcing member 22 of the packaging container 1 engage with each other, whereby the packaging container 1 is attached to the movable body 100 via the attachment portion 23.

[0059] FIG. 9 is a schematic diagram showing a third example of the use of the packaging container 1 according to the first embodiment of the present disclosure.

[0060] 9, the attachment portion 23 is formed from the first side portion 212 of the first reinforcing member 21 attached to the main body portion 11 to the surface portion 224 of the second reinforcing member 22 attached to the lid portion 12. For example, the attachment portion 23 is formed over the entire vertical direction from the first side portion 212 covering the first edge 116 of the main body portion 11 to the surface portion 224 of the second reinforcing member 22 attached to the lid portion 12. For example, a pair of attachment portions 23 are formed at positions facing each other in the reinforcing member 20. The attachment portion 23 is formed as a part of the reinforcing member 20 in a grippable structure that protrudes outward from the outer surfaces of the first side portion 212 and the surface portion 224.

[0061] The movable body 100 transports the packaging container 1 by engaging a gripping portion 130 extending downward from the main body of the movable body 100 with an attachment portion 23 formed on the reinforcing member 20 of the packaging container 1 and gripping the attachment portion 23 with the gripping portion 130. The gripping portion 130 of the movable body 100 and the attachment portion 23 formed on the reinforcing member 20 of the packaging container 1 engage with each other, whereby the packaging container 1 is attached to the movable body 100 via the attachment portion 23.

[0062] FIG. 10 is a schematic diagram showing a fourth example of the use of the packaging container 1 according to the first embodiment of the present disclosure.

[0063] In a fourth example shown in Fig. 10, the attachment portion 23 is formed on the second side portion 214 of the first reinforcing member 21 attached to the main body portion 11. For example, the attachment portion 23 is formed at the first intersection point P1 of the pair of second side portions 214 that face the outer surface 113a of the main body portion 11 along a pair of diagonals of the outer surface 113a of the main body portion 11. For example, the attachment portion 23 is formed at each of the pair of first intersection points P1 that face each other. The attachment portion 23 is formed as a part of the first reinforcing member 21 as an attachment structure for a gimbal mechanism that protrudes outward from the outer surface of the second side portion 214 at the first intersection point P1.

[0064] The movable body 100 transports the packaging container 1 by attaching an attachment portion 140 for the gimbal mechanism, which is formed at the tip of the arm of the movable body 100, to an attachment portion 23 formed on the first reinforcing member 21 of the packaging container 1. The attachment portion 140 of the movable body 100 is attached to the attachment portion 23 formed on the first reinforcing member 21 of the packaging container 1, so that the packaging container 1 is attached to the movable body 100 via the attachment portion 23. At this time, a gimbal mechanism is realized based on the attachment portion 140 of the movable body 100 and the attachment portion 23 of the packaging container 1. For example, the packaging container 1 maintains a horizontal state by the gimbal mechanism, regardless of the attitude of the movable body 100, such as the inclination.

[0065] FIG. 11 is a schematic diagram showing a fifth example of the use of the packaging container 1 according to the first embodiment of the present disclosure.

[0066] In a fifth example shown in FIG. 11, the attachment portion 23 is formed at a first corner portion 211 of the first reinforcing member 21 attached to the main body portion 11. For example, the attachment portion 23 is formed at at least one of the four first corner portions 211 located on the bottom wall 114 side of the main body portion 11. For example, the attachment portion 23 is formed at each of the four first corner portions 211 located on the bottom wall 114 side of the main body portion 11. The attachment portion 23 is formed as a part of the first reinforcing member 21 in the form of abutment protrusion structure that protrudes outward from the outer surface of the first corner portion 211 at the first corner portion 211.

[0067] The movable body 100 transports the packaging container 1 with the packaging container 1 placed on a base 150 attached to the tip of an arm of the movable body 100. At this time, the packaging container 1 is positioned on the base 150 by abutting an attachment portion 23 formed on a first reinforcing member 21 of the packaging container 1 against a protrusion 151 protruding from the placement surface of the base 150 of the movable body 100. The position of the packaging container 1 on the base 150 is fixed by abutting the attachment portion 23 against the protrusion 151. The packaging container 1 is attached to the movable body 100 via the attachment portion 23 by abutting the attachment portion 23 formed on the first reinforcing member 21 of the packaging container 1 against the protrusion 151 of the base 150 of the movable body 100.

[0068] The movable body 100 places the packaging container 1 on the base 150 with the mounting portion 23 formed on the first reinforcing member 21 of the packaging container 1 abutting against the protrusion 151 of the base 150 of the movable body 100, and transports the packaging container 1.

[0069] According to the packaging container 1 according to the first embodiment as described above, it is possible to improve the quality of the packaging container 1. The packaging container 1 can improve the heat insulation of the object contained inside the box body 10 by containing the expandable resin in the box body 10. Similarly, the packaging container 1 can also reduce the weight of the box body 10. In addition, the packaging container 1 can improve the strength of the packaging container 1 by containing a resin having a flexural modulus higher than that of the expandable resin in the reinforcing member 20 attached to the box body 10. As described above, the packaging container 1 can achieve both improved heat insulation and light weight, as well as improved strength. The packaging container 1 can improve more of the characteristics of the packaging container 1 at the same time, thereby improving the quality.

[0070] In the packaging container 1, the reinforcing member 20 has a shape that conforms to the surface shape of the box body 10, so that the reinforcing member 20 can be more closely attached to the box body 10. As a result, the strength of the packaging container 1 is further improved. The reinforcing member 20 in the packaging container 1 can more reliably protect the inner box body 10.

[0071] In the packaging container 1, the reinforcing member 20 is formed on a portion of the surface of the box body 10, so that the molding amount of the reinforcing member 20 formed as the first outer layer can be reduced. Therefore, the packaging container 1 can be made even lighter overall by reducing the weight of the reinforcing member 20.

[0072] The packaging container 1 can obtain the strength required to protect the object contained therein by making the reinforcing member 20 forming the first outer layer have a thickness of 0.5 mm or more. The strength of the packaging container 1 can be improved as the reinforcing member 20 becomes thicker. On the other hand, the weight of the reinforcing member 20 can be reduced by making the reinforcing member 20 forming the first outer layer have a thickness of 10 mm or less. The packaging container 1 can achieve both improved strength and improved lightness by making the reinforcing member 20 have a thickness of 0.5 mm or more and 10 mm or less.

[0073] The packaging container 1 can obtain the heat insulating properties required to protect the object contained therein by having the thickness of the box body 10 forming the second inner layer be 8 mm or more. The packaging container 1 can improve its heat insulating properties as the thickness of the box body 10 increases. On the other hand, the packaging container 1 can reduce the increase in size of the box body 10 by having the thickness of the box body 10 forming the second inner layer be 100 mm or less. The packaging container 1 can improve its heat insulating properties while avoiding an increase in size more than necessary by having the thickness of the box body 10 be 8 mm or more and 100 mm or less.

[0074] The packaging container 1 has a total length of its length, width, and height of 260 cm or less, which facilitates transportation of the packaging container 1 by a moving body 100 for the purpose of delivering a delivery item, for example. The packaging container 1 can be easily transported by the moving body 100. The smaller the total length of the sides of the length, width, and height of the packaging container 1, the more easily the transportability of the packaging container 1 can be improved. On the other hand, the packaging container 1 has a total length of its length, width, and height of 20 cm or more, which enables the packaging container 1 to maintain the spatial volume of the container required to contain the target object. The packaging container 1 has a total length of its length, width, and height of 20 cm or more and 260 cm or less, which enables the packaging container 1 to improve its transportability while maintaining the spatial volume of the container.

[0075] The packaging container 1 has at least one corner portion of the reinforcing member 20 that covers a corner of the box body 10, so that the corner of the box body 10 is protected by the reinforcing member 20 to improve the strength of the packaging container 1. For example, the packaging container 1 has at least one first corner portion 211 that covers a first corner 115 of the main body portion 11 of the box body 10, so that the first corner 115 of the main body portion 11 is protected by the first reinforcing member 21 to improve the strength of the packaging container 1. For example, the packaging container 1 has at least one second corner portion 221 that covers a second corner 125 of the box body 10, so that the second corner 125 of the box body 10 is protected by the second reinforcing member 22 to improve the strength of the packaging container 1.

[0076] If the reinforcing member 20 is composed only of at least one corner portion covering the corner of the box body 10 and does not have a first side portion 212, 222, etc., the packaging container 1 can be made lighter while improving the strength of the packaging container 1 by reinforcing only the corner portion of the packaging container 1.

[0077] The packaging container 1 has a first side portion where the reinforcing member 20 connects a pair of corners along the edge of the box body 10, so that the edge of the box body 10 is protected by the reinforcing member 20 to improve the strength of the packaging container 1. For example, the packaging container 1 has a first side portion 212 where the pair of first corners 211 are connected along the edge of the main body portion 11 of the box body 10, so that the edge of the main body portion 11 is protected by the first reinforcing member 21 to improve the strength of the packaging container 1. For example, the packaging container 1 has a first side portion 222 where the pair of second corners 221 are connected along the edge of the lid portion 12 of the box body 10, so that the edge of the lid portion 12 is protected by the second reinforcing member 22 to improve the strength of the packaging container 1.

[0078] Since the reinforcing member 20 of the packaging container 1 is composed only of the corners and the first side portions and does not have a surface that fills the gap between the first side portions, it is possible to improve the strength of the packaging container 1 while reinforcing only the corners and sides of the packaging container 1, and also to achieve a lightweight container.

[0079] The packaging container 1 has a first side formed in an L-shape along the edges of a pair of outer surfaces that are perpendicular to each other in the box body 10, making it possible to improve the load-bearing characteristics in the direction perpendicular to each of the two inner surfaces that are perpendicular to each other in the first side.

[0080] For example, the packaging container 1 can receive a load from the inner surface of the first side portion 212 along the second edge 117 of the main body portion 11 in two directions, a first direction and a second direction perpendicular to the direction connecting the ceiling wall 124 and the bottom wall 114. For example, the packaging container 1 can receive a load from the inner surface of the first side portion 212 along the third edge 118 of the main body portion 11 in two directions, a direction connecting the ceiling wall 124 and the bottom wall 114 and a first direction perpendicular to the direction. For example, the packaging container 1 can improve the load-bearing characteristics in the up-down direction, which is the direction connecting the ceiling wall 124 and the bottom wall 114, by the first side portion 212.

[0081] The packaging container 1 has a second side portion in which the reinforcing member 20 connects a pair of corners along a diagonal of the outer surface of the box body 10, so that the outer surface of the box body 10 is protected by the reinforcing member 20, thereby improving the strength of the packaging container 1.

[0082] For example, the packaging container 1 has a second side portion 214 that connects a pair of first corner portions 211 along a diagonal line of the outer surface 113a of the main body portion 11, and thus the outer surface 113a of the main body portion 11 can be protected by the first reinforcing member 21 to improve the strength of the packaging container 1. For example, the packaging container 1 has a second side portion 214 that connects a pair of first corner portions 211 along a diagonal line of the outer surface 114a of the main body portion 11, and thus the outer surface 114a of the main body portion 11 can be protected by the first reinforcing member 21 to improve the strength of the packaging container 1. For example, the packaging container 1 has a second side portion 225 that connects a pair of second corner portions 221 along a diagonal line of the outer surface 124a of the lid portion 12, and thus the outer surface 124a of the lid portion 12 can be protected by the second reinforcing member 22 to improve the strength of the packaging container 1.

[0083] The packaging container 1 is capable of protecting the box body 10 disposed inside the reinforcing member 20 by attaching the reinforcing member 20 to the box body 10 so that the reinforcing member 20 has a step toward the outside with respect to the outer surface of the box body 10. In addition, when the packaging container 1 is placed on a loading platform or the like, the bottom wall 114 of the main body 11 can be lifted off the floor surface of the loading platform. When the packaging container 1 is placed on a loading platform or the like, the bottom wall 114 of the main body 11 can be separated from the floor surface of the loading platform and only the first reinforcing member 21 can be in contact with the bottom wall 114 of the main body 11 to maintain the loaded state. This reduces friction between the packaging container 1 and the floor surface when the packaging container 1 is carried from the loading platform, making it easier to slide off. This makes it easier to carry the packaging container 1.

[0084] The packaging container 1 has a rib formed so that the reinforcing member 20 bites into the box body 10, thereby making it possible to improve the attachment strength of the reinforcing member 20 to the box body 10. The packaging container 1 can attach the reinforcing member 20 to the box body 10 more firmly. For example, the packaging container 1 has a first rib 213, thereby making it possible to improve the attachment strength of the first reinforcing member 21 to the main body portion 11 of the box body 10. For example, the packaging container 1 has a second rib 223, thereby making it possible to improve the attachment strength of the second reinforcing member 22 to the lid portion 12 of the box body 10.

[0085] The packaging container 1 can be attached to the flying object by configuring the attachment portion 23 in various ways as shown in Figs. 7 to 11, since the reinforcing member 20 has the attachment portion 23 that is attached to the flying object when the flying object transports the packaging container 1. The packaging container 1 can easily form an attachment structure while ingenuity is applied to various parts of the reinforcing member 20. In the packaging container 1, the attachment structure of the packaging container 1 to the flying object can be formed with a greater degree of freedom. The packaging container 1 can improve the extensibility of attachment to the flying object. The packaging container 1 can improve the attachment to the flying object. In the conventional technology, the technical idea of ​​forming an attachment structure on the reinforcing member on the container side as in the present disclosure is not so much focused on, and it is common to ingenuity the attachment structure on the flying object side rather than the container side. Therefore, the packaging container 1 according to the first embodiment of the present disclosure has the remarkable effects as described above compared to such conventional technology.

[0086] In addition, the packaging container 1 has the reinforcing member 20 that is stronger than the box body 10, which allows the formation of the above-mentioned mounting portion 23. By forming the mounting portion 23 in the strong reinforcing member 20, the packaging container 1 can be attached to the aircraft at a portion of the packaging container 1 that has high strength. Therefore, the packaging container 1 can be stably attached to the aircraft.

[0087] In the packaging container 1, the reinforcing member 20 is integrally attached to the box body 10 by integral molding, and thus the attachment strength of the reinforcing member 20 to the box body 10 can be improved. In the packaging container 1, the reinforcing member 20 can be attached more firmly to the box body 10. For example, in the packaging container 1, the first reinforcing member 21 is integrally attached to the main body portion 11 of the box body 10 by integral molding, and thus the attachment strength of the first reinforcing member 21 to the main body portion 11 can be improved. For example, in the packaging container 1, the second reinforcing member 22 is integrally attached to the lid portion 12 of the box body 10 by integral molding, and thus the attachment strength of the second reinforcing member 22 to the lid portion 12 can be improved.

[0088] In the packaging container 1, the resin contained in the reinforcing member 20 includes a thermoplastic resin, such as ABS, so that the strength of the reinforcing member 20 can be improved compared to the box 10 that contains a foamable resin.

[0089] It is obvious to those skilled in the art that the present disclosure can be realized in other specific forms other than the first embodiment described above without departing from the spirit or essential characteristics thereof.

The reinforcing member 20 may have only one of a corner portion and a first side portion. The reinforcing member 20 may further have not only a corner portion and a first side portion, but also a surface portion that fills the entire gap between the first side portions. Conversely, the reinforcing member 20 may not have the surface portion 224 in the second reinforcing member 22, and the second reinforcing member 22 may be configured as a frame based only on the second corner portion 221 and the first side portion 222, similar to the first reinforcing member 21.

The portions may be formed discontinuously along the second edges 117 over at least a portion of the second edges 117 in the up-down direction.

[0102] In the above first embodiment, the first side portion is formed along the edges of a pair of outer surfaces of the box body 10 that are perpendicular to each other, but is not limited thereto. In the box body 10, the pair of outer surfaces may not be perpendicular to each other. In the box body 10, the pair of outer surfaces may intersect with each other at any angle via an R surface or the like.

Similarly, the corner portion of the reinforcing member 20 may have a shape that follows the shape of the corner of the box body 10.

[0103] Fig. 16 is a cross-sectional view of a packaging container 1 according to a fifth modified example of the present disclosure, corresponding to Fig. 4. Fig. 17 is a cross-sectional view of a packaging container 1 according to a sixth modified example of the present disclosure, corresponding to Fig. 4. The reinforcing member 20 may be formed in a T-shape or an H-shape along the outer surface of the box 10 that is planar.

[0104] 16, the first reinforcing member 21 may be formed in a T-shape along the flat outer surface 113a of the main body 11 of the box 10. The portion formed in a T-shape on the outer surface 113a may be formed continuously along the outer surface 113a over at least a portion of the outer surface 113a in the up-down direction. The portion may be formed discontinuously along the outer surface 113a over at least a portion of the outer surface 113a in the up-down direction.

The portion may be formed discontinuously along the outer surface 113a over at least a portion of the outer surface 113a in the up-down direction.

[0106] In the above first embodiment, the reinforcing member 20 is attached to the box body 10 so as to have a step toward the outside with respect to the outer surface of the box body 10, but the present invention is not limited thereto. The reinforcing member 20 may be attached to the box body 10 so that the outer surface of the reinforcing member 20 and the outer surface of the box body 10 are flush with each other. For example, the first reinforcing member 21 may be attached to the main body 11 so that the outer surface of the reinforcing member 20 and at least one of the outer surfaces 113a and 114a are flush with each other. For example, the second reinforcing member 22 may be attached to the lid 12 so that the outer surface of the reinforcing member 20 and the outer surface 124a are flush with each other.

[0107] The packaging container 1 is attached to the box body 10 so that the reinforcing member 20 is flush with the outer surface of the box body 10, and this can reduce the overall air resistance by suppressing the air resistance caused by the steps of the box body 10 and the reinforcing member 20 when the packaging container 1 is transported by the moving body 100, for example. This allows the moving body 100 that transports the packaging container 1 to reduce the energy consumed by the air resistance associated with transportation. The moving body 100 can achieve energy saving when transporting the packaging container 1. In addition, the packaging container 1 can also improve noise reduction when transported by the moving body 100.

[0108] In the first embodiment, the reinforcing member 20 has a rib formed to bite into the box body 10, but is not limited thereto. The reinforcing member 20 may not have such a rib. Conversely, the reinforcing member 20 may have a rib based on another configuration and arrangement instead of or in addition to the configuration and arrangement of the ribs shown in FIG. 3 and FIG. 5. For example, the first rib 213 may also be formed on the inner surface of the first side portion 212 covering the first edge 116 so as to bite into each of the four first edges 116 of the main body portion 11. For example, the second rib 223 may also be formed on the inner surface of the first side portion 222 covering the first edge 126 so as to bite into each of the four first edges 126 of the lid portion 12.

[0109] In the above first embodiment, the reinforcing member 20 has been described as having the attachment portion 23 that is attached to the flying object when the flying object carries the packaging container 1, but this is not limited thereto. The reinforcing member 20 may not have such an attachment portion 23. The packaging container 1 may not be one that is carried by a moving object 100 including an flying object. Alternatively, the packaging container 1 may be carried by a moving object 100 including an flying object even if it does not have the attachment portion 23. For example, the packaging container 1 may be carried by the moving object 100 without the attachment portion 23 by being housed inside the main body of the moving object 100 as an flying object.

[0110] In the first embodiment, the mounting portion 23 is exemplified as having the configurations shown in Fig. 7 to Fig. 11, but is not limited to these configurations. The shape, pattern, size, arrangement, orientation, type, number, etc. of the mounting portion 23 are not limited to the above description and the contents illustrated in the drawings. The shape, pattern, size, arrangement, orientation, type, number, etc. of the mounting portion 23 may be arbitrarily configured as long as the function can be realized.

[0111] For example, in the first embodiment, the attachment portion 23 is described as being formed as part of the first reinforcing member 21 with a hook structure that protrudes outward from the outer surface of the first side portion 212 in a rectangular frame shape at the center of the first side portion 212 as shown in Fig. 3, but is not limited to this. The attachment portion 23 may be formed in the first reinforcing member 21 as a portion where the first side portion 212 is bent outward so that a gap is formed between the first edge 116 and the first side portion 212 at the center of the first side portion 212.

[0112] In the above first embodiment, the reinforcing member 20 is described as being integrally attached to the box body 10 by integral molding, but the present invention is not limited thereto. The reinforcing member 20 may be attached to the box body 10 in any manner other than integration by integral molding. For example, the reinforcing member 20 may be attached to the box body 10 by adhesion using an adhesive, double-sided tape, or the like.

[0113] In the first embodiment, the reinforcing member 20 is configured so that the first reinforcing member 21 and the second reinforcing member 22 are not overlapped with each other and are flush with each other when the packaging container 1 is closed, but is not limited thereto. The reinforcing member 20 may be configured so that one of the first reinforcing member 21 and the second reinforcing member 22 overlaps the other from the outside at an arbitrary position on the outer surface of the other. The reinforcing member 20 may be configured so that a different reinforcing member overlaps from the outside at an arbitrary position on the outer surface of at least one of the first reinforcing member 21 and the second reinforcing member 22. For example, the reinforcing member 20 may be configured so that a different reinforcing member overlaps from the outside at an outer surface of at least one of the first corner portion 211 of the first reinforcing member 21 and the second corner portion 221 of the second reinforcing member 22.

[0114] In the first embodiment, the thickness of the reinforcing member 20 is uniform overall, but is not limited to this. The thickness of the reinforcing member 20 may vary depending on the reinforcement location. For example, the thickness of the first corner portion 211 of the first reinforcing member 21 may be greater than the thickness of the first side portion 212. For example, the thickness of the second corner portion 221 of the second reinforcing member 22 may be greater than the thickness of the first side portion 222.

[0115] In the above first embodiment, the moving body 100 has been described as including an air vehicle such as a flying drone, but is not limited thereto. The moving body 100 may include any vehicle, vehicle, submarine, etc. The moving body 100 may include, for example, a submarine such as a drone for underwater movement. The moving body 100 may include, for example, a vehicle such as a hovercraft that can move on at least one of water and land.

[0116] The configuration of the packaging container 1 in the first embodiment is not limited, and for example, the reinforcing member 20 containing resin may be further molded integrally with a metal member. For example, the reinforcing member 20 may be further molded integrally with a metal member such as a hinge that connects the main body 11 and the lid 12. For example, the reinforcing member 20 may be configured such that the mounting portion 23 that is attached to the aircraft when the aircraft transports the packaging container 1 is not a part of the reinforcing member 20 but is a metal member made of a metal different from the resin, and further molded integrally with the mounting portion 23.

[0117] Second embodiment Fig. 18 is an external perspective view showing a packaging container 1 according to a second embodiment of the present disclosure in an open state. Fig. 18 corresponds to Fig. 2. In the above first embodiment, the reinforcing member 20 is described as being formed on a portion of the surface of the box body 10, but this is not limited thereto. As shown in Fig. 18, the reinforcing member 20 may be formed on the entire surface of the box body 10. For example, the first reinforcing member 21 of the reinforcing member 20 is formed on each of the outer surfaces of the main body 11 of the box body 10 so as to cover the entire outer surface.

[0118] In the packaging container 1, the reinforcing member 20 is formed on the entire surface of the box body 10, so that it is possible to increase the molding amount of the reinforcing member 20 formed as the first outer layer. Therefore, it is also possible to further improve the overall strength of the packaging container 1 by improving the strength of the reinforcing member 20.

[0119] Other configurations, functions, effects, and modifications described in the first embodiment also apply to the second embodiment. The corresponding descriptions in the first embodiment also apply to the packaging container 1 according to the second embodiment.
