Description of the Related Art Conventionally, for the purpose of protecting a packaged object when the packaged object is transported or handled, the packaged object is stored and packaged inside a packaging container. As such a packaging container, for example, a box-shaped packaging container such as a cardboard box is generally used.

  However, since many packaging containers are rectangular parallelepiped boxes as described above, it is necessary to lift and carry them, for example, during transportation. Furthermore, when there are box-shaped packaging containers having different sizes, there is a problem that if they are stored in the same storage space, the gap increases and the storage efficiency decreases.

  Further, conventionally, a packaged object is sandwiched from above and below by a pair of supports in which an elastic sheet is stretched on a plate-like frame body, and the entire package is placed in a storage container. Hammock packaging that is held away from the wall has been proposed, but in the case of such a hammock packaging, there is a possibility that the position of the object to be packaged sandwiched between the upper and lower elastic sheets may be shifted and kept horizontal. There is a need. However, when handling a conventional packaging container, there is a problem that it is difficult to keep it completely horizontal without being inclined.

  In view of the above points, an object of the present invention is to provide a packaging container that can be easily transported and can keep a packaged item in a horizontal state. Furthermore, it is another object to provide a packaging container that can improve the storage efficiency in the storage space.

  Thereby, no matter what direction the first container (10) is, the second container (12) can freely rotate with respect to the first container (10). For this reason, the to-be-packaged object (17) accommodated in the inside of the 2nd container (12) can always be kept horizontal. Furthermore, the operator can roll and convey a spherical packaging container in the case of conveyance. Therefore, it is not always necessary to lift the spherical packaging container at the time of transportation, and it can be easily transported.

  In the invention according to claim 2, a third spherical container (11) of a spherical hollow body which is accommodated in the first container (10) and accommodates the second container (12) therein. The first surface of the first container (10) and the outer surface of the third container (11) are located on a first straight line passing through the center of the third container (11). Connected at two locations by a first connecting member (13, 14) comprising a shaft (13) and a first bearing (14), the inner surface of the third container (11) and the second container (12) The outer surface is a second rotating shaft (15) and a second bearing (16) that are located on a second straight line that passes through the center of the second container (12) and is orthogonal to the first straight line. It is characterized by being connected at two places by a second connecting member (15, 16) made of Thereby, the 2nd container (12) can have the freedom degree of two axes to the 1st container (10).

  In the invention according to claim 3, the outer surface of the second container (12) is provided with a plurality of support members (18) having a rotatable sphere (18c) at the tip, and the support member (18). The sphere (18c) is pressed against the inner surface of the first container (10). Furthermore, in the invention according to claim 4, a plurality of support members (18) having a sphere (18c) which is rotatable at the tip are provided on the inner surface of the first container (10), and the support member (18). The sphere (18c) is pressed against the outer surface of the second container (12).

  Thereby, when the spherical body (18c) rotates, the second container (12) can have a degree of freedom in all directions with respect to the first container (10).

  In the invention according to claim 5, the center of gravity of the second container (12) is located below the center of the second container (12) in a state in which the article to be packaged (17) is not stored. It is characterized by having. Thereby, even when the packaged item (17) is located at the center of the second container (12), the center of gravity can be shifted from the center of the second container (12).

  In the invention according to claim 6, the second container (12) can be divided into two hemispherical members (12a, 12b), and the opening surfaces of the two hemispherical members (12a, 12b) The elastic sheets (23, 24) are stretched over each other, and the packaged object (17) has elasticity of the elastic sheet (23) of the first hemispherical member (12a) and the elasticity of the second hemispherical member (12b). It is characterized by being sandwiched and held between the sheet (24).

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a cross-sectional view of the spherical packaging container 100 of the first embodiment. As shown in FIG. 1, the spherical packaging container 100 includes three containers 10 to 12 having a spherical hollow body. The containers 10 to 12 include an outer container 10 located on the outermost side, an intermediate container 11 located on the middle, and an inner container 12 located on the innermost side. The diameters of these containers 10 to 12 are in the order of outer container 10> intermediate container 11> inner container 12. As shown in FIG. 1, the intermediate container 11 is accommodated in the outer container 10, and the inner container 12 is accommodated in the intermediate container 11. These containers 10-12 are arrange | positioned so that each center may correspond.

  Moreover, the containers 10-12 can be comprised from materials which have rigidity, such as a synthetic resin and a metal, and the synthetic resin which has rigidity is used in this embodiment.

  As shown in FIG. 1, two connection points are provided between the inner surface of the outer container 10 and the outer surface of the intermediate container 11 via first connecting members 13 and 14 each including a rotating shaft 13 and a bearing 14. Connected with. The two rotation shafts 13 are located on a first straight line passing through the center of the intermediate container 11, and the intermediate container 11 is rotatable with respect to the outer container 10.

  Similarly, the inner surface of the intermediate container 11 and the outer surface of the inner container 12 are connected to each other at two connection points via second connecting members 15 and 16 each including a rotating shaft 15 and a bearing 16. Yes. The two rotation shafts 15 are positioned on a second straight line that passes through the center of the inner container 12 and is orthogonal to the first straight line, and the inner container 12 is rotatable with respect to the intermediate container 11. Yes.

  Thereby, the inner container 12 is connected to the outer container 10 via the intermediate container 11 and the first and second connecting members 13, 14, 15, and 16. At this time, since the rotation shaft 13 of the intermediate container 11 and the rotation shaft 15 of the inner container 12 are arranged so as to be orthogonal to each other, the inner container 12 has two degrees of freedom of rotation with respect to the outer container 10. Become. Note that the intermediate container 11, the first connecting members 13, 14 and the second connecting members 15, 16 of the present embodiment correspond to the connecting means of the present invention.

  An article to be packaged 17 is stored inside the inner container 12. At this time, since the article 15 to be packaged is disposed below the inside of the inner container 12, the center of gravity of the inner container 12 becomes lower than the center of the inner container 12 due to the weight of the article 17 to be packaged. As described above, the inner container 12 has a degree of freedom of two-axis rotation with respect to the outer container 10, so the inner container 12 rotates freely regardless of the orientation of the outer container 10. The package 17 is always down. Thereby, the to-be-packaged object 17 accommodated in the inner side container 12 can always be kept horizontal.

  Next, opening and closing of the spherical packaging container 100 will be described with reference to FIG. FIG. 2 shows a state where the containers 10 to 12 are opened.

  In the example shown in FIG. 2A, each of the containers 10 to 12 can be separated into two hemispheres. The two separated hemispheres are configured such that one open end fits into the other open end. Moreover, in the example shown in FIG.2 (b), the two hemispheres which each comprise each container 10-12 are connected so that rotation by the hinge (not shown) at one place is possible.

  Although illustration of the connection members 13-16 is abbreviate | omitted in FIG. 2, each container 10-12 was provided with the two connection points connected with the adjacent containers 10-12, ie, connection members 13-16. It can be divided into two hemispheres at locations avoiding the region. The outer container 10 can be divided into a first outer container 10a and a second outer container 10b, the intermediate container 11 can be divided into a first intermediate container 11a and a second intermediate container 11b, and the inner container 12 can be divided into a first inner container 12a and a second inner container 12a. The inner container 12b can be divided.

  As shown in FIG. 2A, when opening the spherical packaging container 100, the outer container 10 is opened, then the intermediate container 11 is opened, and finally the inner container 12 is opened. In this state, the package 17 is put in and out of the inner container 12. Next, when the spherical packaging container 100 is closed, the inner container 12 is closed, then the intermediate container 11 is closed, and finally the outer container 10 is closed. Thereby, it becomes possible to wrap the article to be packaged 17 in the spherical packaging container 100.

  Next, a method for handling the spherical packaging container 100 will be described with reference to FIGS.

  Since the spherical packaging container 100 is spherical, an operator can roll and transport the spherical packaging container 100 as shown in FIG. Therefore, it is not always necessary to lift the spherical packaging container 100 at the time of conveyance, and it can be easily conveyed. Furthermore, as shown in FIG. 4, a transportation lane 200 for rolling and transporting the spherical packaging container 100 can be provided. In this case, if the lane 200 is inclined, the spherical packaging container 100 is naturally rolled from the high side to the low side due to gravity. Thus, even when the spherical packaging container 100 is rolled, the inner container 12 can always be kept horizontal.

  Further, as shown in FIG. 5, it can be thrown into a storage container 210 that stores the spherical packaging container 100, or as shown in FIG. 6, an operator kicks the spherical packaging container 100 with a foot to another worker. You can also hand it over. 6 shows a rectangular parallelepiped container having an open upper end as an example of the storage container 210 that stores the spherical packaging container 100, the present invention is not limited thereto, and a container having an arbitrary shape may be used as the storage container 210. it can.

  Further, as shown in FIG. 5, the spherical packaging container 100 is stored in a stacked state in the storage container 210. At this time, it is desirable that the sliding friction coefficient of the outer surface of the outer container 10 is 0.42 or less. As a result, it is possible to minimize the catching due to the friction between the adjacent spherical packaging containers 100, and it is possible to smoothly fill the spherical packaging container 100 into the storage container 210. Furthermore, it becomes easy to slip also with respect to the floor surface which installs a spherical packaging container by making the sliding friction coefficient of the outer surface of the outer side container 10 or less into 0.42. Thereby, when the outer container 10 rotates with respect to a floor surface, it becomes easy to keep the inner packaging material 17 horizontal.

  When a plurality of spherical packaging containers 100 are stored in the storage container 210, it is desirable that a plurality of types of spherical packaging containers 100 having different diameters are mixed. Thereby, the packaging container 100 with a small diameter can enter into the clearance generated when a plurality of packaging containers 100 with a large diameter are stored in the storage container 210, and the space filling rate can be improved.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS.

  FIG. 7 is a perspective view showing a state where the spherical packaging container 101 of the second embodiment is closed, and FIG. 8 is a perspective view showing a state where the spherical packaging container 101 is opened.

  As shown in FIGS. 7 and 8, the spherical packaging container 101 includes two containers, an outer container 10 and an inner container 12. Each container 10 and 12 is transparent, and the inside can be seen through. A plurality of support members 18 are fixed to the outer surface of the inner container 12. Each support member 18 is provided so as to stand upright on the outer surface of the inner container 12. In addition, the support member of this embodiment is equivalent to the connection means of this invention.

  FIG. 9 is a perspective view of the support member 18. As shown in FIG. 9, the support member 18 includes a nut 18a that is fixed to the outer surface of the inner container 12, and a bolt 18b that is fitted to the nut 18a. A sphere 18c is rotatably provided at the tip of the bolt 18b. By rotating the bolt 18b, the length of the portion exposed from the nut 18a can be changed, whereby the length of the support member 18 can be adjusted.

  The length of the support member 18 is obtained by halving the length obtained by subtracting the outer diameter of the inner container 12 from the inner diameter of the outer container 10. The tip of the support member 18 provided on the outer surface of the inner container 12 is pressed against the inner surface of the outer container 10. The inner container 12 is supported by a plurality of support members 18, and the inner container 12 floats inside the outer container 10. At this time, since the sphere 18c of the support member 18 and the inner surface of the outer container 10 are in contact with each other, the inner container 12 is independent of the orientation of the outer container 10 inside the outer container 10 by rotating the sphere 18c. Can be rotated.

  As shown in FIGS. 7 and 8, the outer container 10 and the inner container 12 can be divided into two hemispheres 10a, 10b, 12a, and 12b, respectively. The first outer container 10a and the second outer container 10b are rotatably connected by a hinge 19 and can be fixed by a stopper 20. Similarly, the 1st inner side container 12a and the 2nd inner side container 12b are rotatably connected by the hinge 21, and can be fixed with the fastener 22.

  A so-called hammock package is used for the inner container 12 of the present embodiment. Elastic sheets 23 and 24 are stretched over the first inner container 10a and the second inner container 10b so as to cover the respective openings. The package 17 is sandwiched between the two elastic sheets 23 and 24 and is held away from the inner surface of the inner container 12.

  As the elastic sheets 23 and 24, for example, a sheet made of a material selected from polyurethane-based thermoplastic elastomer, polyamide, ethylene-vinyl acetate copolymer, single-site catalyzed polyolefin, polybutylene succinate and polybutylene succinate adipate is suitable. Can be used. In addition, natural rubber, various rubbers, various synthetic rubbers, polyethylene, chlorinated polyethylene, or fluororesin can be used. Depending on the characteristics of these materials, it is preferable to increase the strength by crosslinking or stretching by electron beam irradiation depending on the properties. The form of the elastic sheets 23 and 24 is not limited to a sheet or a film, and may be a net (net-like) or a non-woven fabric. The term “sheet” in the present specification is used to mean not only a sheet but also a net and a non-woven fabric.

  In addition, a weight 25 having a predetermined weight is fixed to a lower portion inside the inner container 12, that is, the second inner container 12b. As described above, by providing the weight 25 at the lower portion of the inner container 12, the center of gravity of the inner container 12 can be made lower than the center of the inner container 12 in a state where the package 17 is not stored in the inner container 12. it can. Thereby, even when the article to be packaged 17 is located at the center of the inner container 12, the center of gravity can be shifted from the center of the inner container 12.

  FIGS. 10A and 10B show a state in which the outer container 10 is rotated. As described above, since the inner container 12 can freely rotate with respect to the outer container 10, as shown in FIGS. 10 (a) and 10 (b), the outer container 10 can be in any orientation. The weight 25 is always downward. Therefore, the package 17 stored in the inner container 12 can always be kept horizontal.

  The same effect as that of the first embodiment can also be obtained by the configuration of the spherical packaging container 101 described above. In addition, in the hammock packaging in which the package 17 is sandwiched between the two elastic sheets 23 and 24, there is a problem that the package 17 is displaced when the packaging container 12 is tilted. Since the packaging container 12 can always keep horizontal, it can prevent that the to-be packaged object 17 shifts | deviates.

  Moreover, by making the outer container 10 and the inner container 12 constituting the spherical packaging container 101 transparent as in the present embodiment, the state of the inner package 17 can be changed without opening the containers 10 and 12. Can be confirmed. Furthermore, only the inner container 12 may be transparent. In this case, if the outer container 10 is opened, the state of the article 17 to be packaged in the inner container 12 can be confirmed.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to FIGS.

  FIG. 11 shows the overall configuration of the transport system of the third embodiment. As shown in FIG. 11, the transfer lane 200 of the third embodiment is branched into a plurality of lanes 200 a, 200 b, and 200 c toward the downstream side. The spherical packaging container 102 is distributed to one of the lanes 200a, 200b, and 200c at the branch point of the transportation lane 200, and is transported to different destinations. In this embodiment, the first lane 200a conveys the spherical packaging container 102 to the vehicle, the second lane 200b conveys the spherical packaging container 102 to the adjacent conveyance lane, The lane 200c is for transporting the spherical packaging container 102 to the ship.

  A guide member 201 for guiding the spherical packaging container 102 to a target destination is provided at a branch point of the transfer lane 200. The guide member 201 can be comprised from the plate-shaped member arrange | positioned in the flow path of the spherical packaging container 102 so that rotation is possible, for example.

  FIG. 12 shows a block configuration of the transport system. As shown in FIG. 12, an IC tag 26 is provided on the spherical packaging container 102 of the third embodiment. The IC tag 26 is a recording medium in which electronic information can be read and written in a non-contact manner, and package information such as a destination (conveyance destination) and type of the packaged item is stored in advance.

  The transport lane 200 is provided with a reading device 202, an actuator 203, a passage detection sensor 204, and a control device 205. The reading device 202 reads information stored in the IC tag 26 in a non-contact manner. The reading device 202 is provided on the upstream side of the guide member 201 in the transport lane 200. The actuator 203 operates the guide member 201. The passage detection sensor 204 detects that the spherical packaging container 102 has passed through the guide member 201. The control device 205 controls the actuator 203 based on signals from the reading device 202 and the passage detection sensor 204.

  Next, the conveyance method of the spherical packaging container 102 by the conveyance system of this embodiment is demonstrated.

  First, when the spherical packaging container 102 flows down the transport lane 200 and approaches the branch point, the package information of the IC tag 26 incorporated in the spherical packaging container 102 is read by the reading device 202. Then, the control unit 205 controls the actuator 203 so that the spherical packaging container 102 is guided to the target destination by the guide member 201 based on the destination (conveyance destination) of the packaged item included in the package information.

  As a result, the spherical packaging container 102 is distributed to the intended destination at the branch point of the transport lane 200. When the passage detection sensor 204 detects the passage of the spherical packaging container 102, the control unit 205 controls the actuator 203 so that the position of the guide member 201 is returned to the original state.

  With the above configuration, the spherical packaging container 102 flowing down the transfer lane 200 can be automatically distributed to a target destination, and the operator does not need to perform the sorting operation of the spherical packaging container 102.

  In addition, as shown in FIG. 11, an extrusion device 220 that imparts kinetic energy to the spherical packaging container 102 with an elastic member such as a spring is provided in the transfer lane 200 in which the spherical packaging container 102 is conveyed in the second lane 200 b. Is provided. When the operator releases the spring that has been pulled and compressed, kinetic energy is imparted to the spherical packaging container 102 by the elastic energy of the spring. Thereby, the spherical packaging container 102 is pushed out vigorously and rolls on the transportation lane 200. By providing such an extrusion device 220, the spherical packaging container 102 can be transported without using gravity even when the transport lane 200 is not inclined downward.
