    Title: Container
    Background of the Present Invention Field of Invention
    The present invention relates to a container, and in particular, to a container having a buffer device.
    Description of Related Arts
    Transport with containers is a main form of international transport of goods. The external dimensions, namely the length, the width and the height, of a standard container comply with the provisions in the ISO standards regarding the container. At present, the specifications of the containers include, for example, 20-ft cabinets, 40-ft cabinets, 40-ft tall cabinets, 45-ft tall cabinets, and special containers. The types of the containers of different specifications may be further classified into common containers, tall containers, open-top containers, flat-bottom containers, and containers for a folding platform. In transport process, to facilitate the lifting and stacking of the container as well as positioning connection and case protection in the delivery, top corner fittings and bottom corner fittings (also collectively referred to as "corner fittings") are disposed at end corner portions of the container, and are fixed by using a twist lock (also referred to as "turn lock").
    In a circulation process of the container, as the container itself does not have a buffering function, it is difficult to avoid collision by the corner fittings-based or forklift-based loading/unloading method, thus resulting in damage to the goods in the container. Taking an international maritime container used in the land-and-sea entire transport as an example, when loading/unloading is performed by using a transport truck or on/from a ship, an impact acceleration is produced during the operations at a warehouse, a goods terminal or a container terminal. The impact acceleration is produced instantly, non-periodically and irregularly, and the damage degree of the impact acceleration on the goods stowed in the container completely depends on the magnitude and duration of the impact acceleration. In other words, when a container is descended to contact the ground, the deck, or a top face of another container, a floor face thereof may produce a great impact acceleration in a short period of time, and then, the impact acceleration is conducted to the goods in a short period of time to bring damage to the goods in the container. Especially, when the goods are loaded in the container or the goods are fastened in an inappropriate manner, a greater impact acceleration is probably produced due to jumping or moving of the goods, thereby bringing an immeasurable damage to the goods.
    To solve the problem, one method generally used in the industry is to wholly pack the goods with buffering materials and then place the packed goods in the container, or improve operation accuracy or proficiency of the personnel who transport and move the container. For example, for the issue that the buffering function of the existing international maritime container is insufficient, a lot of wood is generally used in the prior art to perform wooden-case packing. The following defects exist in the wooden-case packing: the use of tools such as a hammer or an iron bar easily to perform the unpacking process of the container brings damage to the goods in the container. Moreover, the wooden-case packing uses a lot of wood, thus resulting in waste of resources, high cost in waste processing, and environmental pollution. For example, 2.5 tons of wood need to be used on average for 40-ft (30 m3) goods; moreover, the wood packing as well as the unpacking process described above requires a long operating time. For example, after the arrival of the goods, the time required in the unpacking occupies 15% of the total time required in unpacking and moving the goods to a specific place, which is unfavorable to the reduction of time and manpower cost.
    On the other hand, as such precision apparatuses as Liquid Crystal Displays (LCDs), semi-conductor apparatuses, solar energy equipment and numerically-controlled machine tools tend to become larger and larger, disassembling the apparatuses takes a long time, and moreover, has bad effects on the apparatuses. When theses apparatuses cannot be placed in the existing container, non-closed flat container is mostly used for transport, and packaging is performed in the foregoing wooden-case packing manner, so that loading/unloading can be performed in the dock in an open-air environment and buffering protection can be provided. However, when the flat container is used, the operation schedule is easily affected by the weather, and it is also very difficult to control the transport quahty. In addition, the flat containers cannot be heaped (stacked or stowed), which greatly reduces the effective utilization of the transport space, results in decrease of the number of cases loadable in the same space during the transport or moving (for example, the effective space utihzation of loading space is more important for a seagoing ship), and thereby causes cost of the transport, storage, and logistics management to be increased.
    Therefore, a technical problem to be solved by persons in the related art currently is to provide a container capable of loading large-sized precision apparatuses and provide desirable buffering protection, so as to ensure the safety and stability of the loaded goods during the loading/unloading process, and meanwhile, improve the effective utihzation of the transport space and reduce the cost in transport and storage, thereby alleviating the defects in the prior art.
    Summary of the Present Invention
    In view of the defects in the prior art, one objective of the present invention is to provide a container, so as to solve the problem in the prior art that the goods in the container are easily damaged in loading/unloading operations as the container does not have a buffer function.
    Another objective of the present invention is to provide a container, so as to solve the problem in the prior art of low transport space effective utihzation incurred as the flat containers cannot be heaped or stacked.
    Still another objective of the present invention is to provide a container, so as to solve such problems in the prior art as waste of resources, high cost in waste processing, environmental pollution, etc.
    To achieve the foregoing objectives and other related objectives, the present invention provides a container placed in a stacking area having many corner fittings, and the corner fittings comprise multiple first corner fittings and second corner fittings, the respective second corner fittings having a reference center distance from the respective first corner fittings. The container at least comprise a container body and positioning buffers, wherein each bottom corner portion of the container body is disposed with a first bottom corner fitting correspondingly connected the respective first corner fittings, a cavity exists in each side wall of the container body located at an outer side of the respective first bottom corner fittings, and the multiple positioning buffers are disposed in the cavities respectively. The positioning buffer comprises a buffer device and a second bottom corner fitting connected to the buffer device, and a center distance between the second bottom corner fitting and the first bottom corner fitting is equal to the reference center distance between the first corner fitting and the second corner fitting in the stacking area. When the container body is at a suspending state, the buffer device is dragged by the gravity of the second bottom corner fitting and then stretches out of the container body to contact the second corner fitting, and enters the cavity at the uniform velocity due to the stress of the gravity of the container body when the second bottom corner fitting and the second corner fitting are connected with each other, so as to cushion the container body.
    In the container according to an embodiment of the present invention, the stacking area is a seagoing ship deck area for carrying a first specification standard case complying with the ISO standard, and the reference center distance between the first corner fitting and the second corner fitting in the seagoing ship deck area complies with the ISO standards.
    In the container according to another embodiment of the present invention, the stacking area is a case top-face area formed by at least three first specification standard cases arranged side by side. The first corner fitting and the second corner fitting in the case top-face area are respectively located on two adjacent first specification standard cases, and the reference center distance between the first corner fitting and the second corner fitting complies with the ISO standards.
    The container of the present invention is a second specification standard case complying with the ISO standards, and the distance between two first bottom corner fittings at the same side of the second specification standard case is equal to a distance between two first corner fittings at the same side of the first specification standard case.
    The positioning buffer further comprises a locking member disposed on a side wall of the cavity, and the locking member comprises a through hole passing through the side wall of the cavity and a pin disposed in the through hole for locking the second bottom corner fitting into the cavity. Correspondingly, the second bottom corner fitting has an insertion hole corresponding to the pin.
    In the container of the present invention, the positioning buffer further comprises a spring disposed between the buffer device and the second bottom corner fitting. The buffer device is an oil-pressure buffer, a hydraulic buffer, or an air-pressure buffer.
    Specifically, the oil-pressure buffer comprises a sleeve fixed in the cavity, a piston movably disposed in the sleeve, a piston rod connected to the piston, and oil-pressure oil filled in the sleeve and sealed by the piston. The sleeve comprises an inner cylinder and an outer cylinder spaced from the inner cylinder, and multiple orifices pass through the inner cylinder. The oil-pressure oil is discharged, when being pushed by the piston, through the orifices to a sandwiched cavity formed by the inner cylinder and the outer cylinder to generate oil-pressure resistance, so as to absorb energy generated by the pushing of the piston. The second bottom corner fitting is fixed to the piston rod of the oil-pressure buffer by a screw, the spring is disposed around the piston rod, and two ends of the spring are connected to the sleeve and the second bottom corner fitting respectively.
    In the container of the present invention, each top corner portion of the container body further comprises a first top corner fitting located in the same vertical fine with the first bottom corner fitting, a second top corner fitting located in the same vertical line with the second bottom corner fitting, and a third top corner fitting disposed at an outer side of the second top corner fitting and located at a top-corner end of the container body. Specifically, the numbers of the first bottom corner fittings, the positioning buffers and the third top corner fittings are all four.
    In the container of the present invention, the floor of the container body is disposed with multiple bundling rings or rope hooks for a bundling belt to vertically bind the goods in the container. Specifically, the bundling rings or rope hooks are fixed on the floor by lashing bolts. The floor is a stainless steel plate floor.
    In the container of the present invention, inner side walls around the container body are disposed with multiple bundling rails for the bundling belt to horizontally bind the goods in the container. The bundling rails are fixed on the side walls by lashing bolts.
    As described above, the container of the present invention has the following beneficial effects.
    1. In the container of the present invention, a positioning buffer is disposed at each bottom corner portion of the container body. When the container is loaded on or unloaded from a seagoing container trailer or a container ship by using a crane, an impact force generated due to collision can be efficiently reduced, thereby ensuring the safety and stability of the goods in the container. Moreover, as the floor and the side walls of the container body are all disposed with bundling rings and bundling rails for the bundling rings and bundling belts to vertically and horizontally bind the goods in the container, the goods in the container are internally fixed, thereby further avoiding damage to the goods in the container during the loading/unloading operations.
    2. In the container of the present invention, the bottom corner fittings and the top corner fittings are disposed on the bottom corner portions and the top corner portions of the container body, so that the containers can be stacked or stowed. Moreover, as the disposition of the corner fittings of the container of the present invention complies with the ISO standards, the container of the present invention and containers of other specifications can be stacked or stowed together, thereby improving effective utihzation of the transport space, reducing the transport and storage costs, and particularly having a higher industrial application value for the seagoing ships with limited and precious transport space.
    3. The container of the present invention is a totally closed container, thereby overcoming the defects in the prior art that the loading/unloading schedule for the flat container is easily affected by the weather, and solving such problems existing in the prior art as waste of wood resources, high cost in waste processing and environmental pollution resulted from the wood packing manner, and effectively reducing the transport and loading/unloading costs.

    The present invention provides a container placed in a stacking area with multiple corner fittings. The corner fittings include multiple first, corner fittings and multiple second corner fittings, and the respective second corner fittings have a reference center distance from the respective first, corner fittings correspondingly. In a specific embodiment, the first corner fittings and the second corner fittings are top-face corner fittings capable of being fit with twist locks of container complying with the ISO standards, and the top-face corner fittings have top-face holes fit with the twist locks.
    To simplify the description, the reference center distance between the first corner fitting and the second corner fitting adjacent to the first corner fitting is referred to as LI, and a reference center distance between two first corner fittings or between two second corner fittings is referred to as L2, wherein the reference center distance is a center hole distance located between top-face holes in the corner fittings, and the center hole distance complies with the ISO standards.
    It should be particularly noted that, the container of the present invention may also be placed, for example, on an open ground or in an area of a cabin deck without a fixing member or a positioning member. In other words, in the case that no substantial change is made to the technical content regarding the specific structure of the container of the present invention, the foregoing area is also considered to be suitable for implementing the present invention.
    In an embodiment, referring to Fig. 1, a schematic view of a stacking area formed by positioning connection beams and disposed on a deck of container ship is shown. As shown in Fig. 1, the stacking area may also be a deck area of a seagoing ship for carrying a first specification standard case complying with the ISO standards, and the deck area of the seagoing ship is formed by multiple positioning connection beams 1. First corner fittings 11 and second corner fittings 12 are integrally formed on the positioning connection beams 1, and a reference center distance between the first, corner fitting 11 and the second corner fitting 12 complies with the ISO standards. The reference center distance between the first corner fitting 11 and the second corner fitting 12 adjacent to the first corner fitting 11 is LI, and a reference center distance between two first corner fittings 11 or two second corner fittings 12 is L2, and the reference center distance is a center hole distance between top-face holes in the corner fittings, and the positioning connection beam 1 is disposed on the deck of container ship and used for positioning and fixing the container when the container is loaded/unloaded. In practical conditions, the deck of container ship has multiple positioning connection beams 1 which are parallel to each other and used for fixing the first specification container.
    In another embodiment, Fig. 2 is a schematic view showing that containers of the present invention are stacked at a stacking area formed by the first specification standard case. As shown in Fig. 2, the stacking area is a top-face area formed by at least three first specification standard cases 21, 22 and 23 arranged side by side. A first corner fitting 211 and a second corner fitting 221 or 231 in the top-face area are respectively located on two adjacent first specification standard cases 21, 22, or 21, 23, that is, as shown in Fig. 2, the first corner fitting 211 is located on the first specification standard case 21, and the second corner fittings 221 and 231 adjacent to the first corner fitting 211 are respectively located on two first specification standard cases 22 and 23 at two sides of the first specification standard case 21. A reference center distance between the first corner fitting 211 and the second corner fitting 221 or 231 adjacent to the first corner fitting 211 is LI, a reference center distance between two first corner fittings 211 is L2, and the reference center distance is a center hole distance between top-face holes in the corner fittings.
    It should be particularly noted that, for the convenience of the illustration of the principle and efficacy of the present invention, in the following embodiments, the case that the stacking area of the container of the present invention is the top-face area formed by at least three first specification standard cases 21, 22, and 23 arranged side by side is taken as an example for illustration, and is described in detail later.
    The first specification standard cases 21, 22 or 23 may be any one type of, for example, a 20-ft cabinet, a 40-ft cabinet, a 40-ft tall cabinet, a 45-ft tall cabinet and a special container, but the present invention is not limited thereto. The standard specification of the container is known by persons skilled in the art, so the details are not described herein again.
    As shown in FIG. 2, the container 3 of the present invention at least includes a container body 31 and multiple positioning buffers 32 disposed at each bottom corner portion of the container body 31. The container of the present invention is a second specification standard case of a specification different from that of the first specification standard case. In other words, in this embodiment, the case that the width of the first specification standard cases 21, 22 and 23 is 2490 mm and the width of the second specification standard case 3 is 2990 mm is taken as an example for illustration, but the present invention is not limited thereto. In other embodiments, the first specification standard case and the second specification standard case may have other specification dimensions. However, it should be noted that, the specification dimension of the second specification standard case of the present invention shall be greater than that of the first specification standard case.
    Each bottom corner portion of the container body 31 is disposed with a first bottom corner fitting 311 correspondingly connected to each first corner fitting 211, and a side wall of the container body located at an outer side of each first bottom corner fitting 311 has a cavity 312. In this embodiment, a distance between two first bottom corner fittings 311 at the same side of the container body 31 is equal to a distance between two first corner fittings 211 at the same side of the first specification standard case 21 (that is, a reference center distance between the two first corner fittings 211 is L2). In other words, a distance between two first bottom corner fittings 311 at the same side of the container body 31 is L2, thereby ensuring that, when the container 3 being the second specification standard case is stowed on the top-face area formed by the first specification standard cases 21, 22, and 23, the two first bottom corner fittings 311 of the container can fully correspond to the two first corner fittings 211 on the first specification standard case 21.
    In this embodiment, the cavity 312 is formed inside the side wall of the container body 31, and is located at the outer side of the first bottom corner fitting 311. There are four first bottom corner fittings 311 and four cavities 312 respectively distributed at four bottom corner portions of the container body 31.
    Four positioning buffers 32 are respectively disposed in the cavities 312, and each includes a buffer device 321, a second bottom corner fitting 322 connected to the buffer device 321, a locking member 323 and a spring 324.
    Fig. 3 and Fig. 4 are schematic views showing a process of stacking the containers of the present invention in the stacking area formed by the first specification standard cases.
    A center distance between the second bottom corner fitting 322 and the first bottom corner fitting 311 is equal to the reference center distance between the first corner fitting 211 and the second corner fitting 221 in the top-face area formed by the first specification standard cases 21, 22, and 23. That is, as shown in Fig. 3, the reference center distance between the first bottom corner fitting 311 and the second bottom corner fitting 322 adjacent to the first bottom corner fitting 311 is LI, thereby ensuring that, when the container 3 being the second specification standard case is stowed on the top-face area formed by the first specification standard cases 21, 22 and 23, the two second bottom corner fittings 322 of the container 3 may respectively correspond to the two second corner fittings 221 and 231 located on the first specification standard cases 22 and 23.
    Under a suspending state of the container body 31, the buffer device 321 is dragged by the gravity of the second bottom corner fitting 322, stretches out of the container body 31 to contact the second corner fitting 221 or 231, and enters the cavity 312 at a uniform velocity due to the stress of the gravity of the container body 31 when the second bottom corner fitting 322 and the second corner fitting 221 or 231 are connected with each other, so as to cushion the gravity of the container body 31.
    Fig. 5 is a schematic view showing a locking state of the positioning buffer of the container of the present invention. As shown in Fig. 5, the positioning buffer 32 further includes a locking member 323 which is disposed on a side wall of the cavity 312 and includes a through hole (not shown) passing through the side wall of the cavity 312 and a pin (not shown) disposed in the through hole for locking the second bottom corner fitting 322 into the cavity 312. Correspondingly, the second bottom corner fitting 322 has an insertion hole (not shown) corresponding to the pin, so as to lock the second bottom corner fitting 322 into the cavity 312 when the positioning buffer 32 is not used.
    The positioning buffer 32 further includes a spring 324 disposed between the buffer device 321 and the second bottom corner fitting 322. In a specific embodiment, the buffer device 321 may be an oil-pressure buffer, a hydraulic buffer, or an air-pressure buffer, and is used for cushioning impact acceleration generated when the container body 31 is descended to contact the ground, the deck, or a top face of another container.
    In this embodiment, as an example, the oil-pressure buffer is used as the buffer device 321 for illustration. Referring to Fig. 6 and Fig. 7, a schematic structural view and a schematic principle view of the oil-pressure buffer in the container of the present invention are respectively shown. As shown in Fig. 6 and Fig. 7, the buffer device 321 includes a sleeve 3211, a piston 3212, a piston rod 3213, and oil-pressure oil 3214.
    The sleeve 3211 is fixed in the cavity 312 by a locking screw. Specifically, the sleeve 3211 includes an inner cylinder 32111 and an outer cylinder 32112 spaced from the inner cylinder 32111, and multiple orifices 32113 piercing through a side wall of the inner cylinder are distributed on the inner cylinder 32111, so that the oil-pressure oil 3214 in the inner cylinder 32111 is discharged under pressure through the orifices 32113 into a sandwiched cavity formed by the inner cylinder 32111 and the outer cylinder 32112.
    The piston 3212 is movably disposed in the inner cylinder 32111 of the sleeve, and is connected to the piston rod 3213 with a screw. The oil-pressure oil 3214 is filled in the inner cylinder 32111 and is sealed by the piston 3212. The oil-pressure oil 3214 may be discharged under pressure through the orifices 32113 into the sandwiched cavity formed by the inner cylinder and the outer cylinder to generate oil-pressure resistance, so as to absorb energy generated by the pushing of the piston 3212.
    The second bottom corner fitting 322 is fixed to the piston rod 3213 of the oil-pressure buffer by a screw. The spring 324 is disposed around the piston rod 3213 and the two ends thereof are connected to the sleeve 3211 and the second bottom corner fitting 322 respectively, so as to provide an elastic restoring force to assist the gravity of the second bottom corner fitting 322. Therefore, the piston rod 3213 stretches out of the container body 31 to prepare for the next operation when the container body 31 is at a suspending state.
    When the container body 31 is lifted up, the piston rod 3213 of the buffer device 321 stretches out of the container body 31 due to the gravity of the second bottom corner fitting 322 and the elastic force of the spring, so that the second bottom corner fitting 322 fixed on the piston rod 3213 contacts the second corner fitting 221 or 231 located in a lower stacking area. When the container body 31 is laid down, the second bottom corner fitting 322 is connected to the second corner fitting 221 or 231. The container body 31 may impose an impact force on the second corner fitting 221 or 231 due to its gravity. At this time, the piston rod 3213 drives the piston 3212 to shde upward along an inner surface of the inner cylinder 32111, and the oil-pressure oil 3214 of the fully-filled inner cyhnder 32111 is discharged under pressure through the orifices 32113 to the sandwiched cavity formed by the inner cylinder 32111 and the outer cylinder 32112, thereby generating the oil-pressure resistance to absorb impact energy. As the piston slides upward, the piston blocks theses orifices 32113, so a flow area of the oil-pressure oil is reduced. Therefore, in the entire sliding section of the piston 3212, a certain oil-pressure resistance force is basically generated for the operation thereof. This makes it possible to efficiently alleviate the impact force resulted from collision, ensuring the reduction of the descending speed of the container body 31 and thereby providing a cushioning effect and protection for the goods in the container.
    Referring to Fig. 8 and Fig. 9, schematic structural views of a bundling ring and a bundling rail disposed in the container of the present invention are respectively shown. As shown in Fig. 8 and Fig. 9, to further provide the cushioning effect and protection for the goods in the container, a floor 33 of the container body 31 in the container according to the present invention has multiple bundling rings 351 or rope hooks (not shown) disposed thereon so that a bundling belt (not shown) may vertically bind the goods in the container, wherein the bundling rings 351 or rope hooks (not shown) are fixed on the floor 33 by lashing bolts 361. Specifically, the bundling rings 351 and the lashing bolts 361 are integrally formed. The floor 33 is a stainless steel plate floor, that is, a Steel Use Stainless (SUS) plate.
    Meanwhile, inner side walls 34 around the container body 31 have multiple bundling rails 352 disposed thereon so that the bundling belt (not shown) may horizontally bind the goods in the container. In this embodiment, the bundling rails 352 are fixed on the side walls by lashing bolts 362. Specifically, the side walls 34 include left and right side walls, a single-face side wall door, front and rear walls, front and rear doors, etc. The bundling rails 352 on each side wall are disposed in three layers, that is, upper layer, middle layer and lower layer, so that bundling belts may be used to horizontally bind the goods loaded in the container at different heights, thereby protecting the goods in the container from damage resulted from collision of the goods during the loading/unloading operations.
    As mentioned above, the container 3 according to the present invention has the positioning buffer 32 disposed at its each bottom corner portion. Therefore, when the container is loaded to or unloaded from the land, a seagoing container trailer, or a container ship by using a crane, the impact force resulted from collision can be efficiently reduced, thereby ensuring the safety and stability of the goods in the container. Moreover, as the floor and the side walls of the container body are all disposed with bundling rings and bundling rails for bundling belts to vertically and horizontally bind the goods in the container, the goods in the container are internally fixed, thereby further avoiding the damage to the goods in the container during the loading/unloading operations. The more prominent advantage is that it is possible to avoid such problems existing in the prior art as waste of wood resources, high cost in waste processing, environmental pollution resulted from the wood packing manner.
    Fig. 10 is a schematic structural view showing distribution of corner fittings of the container according to the present invention. As shown in Fig. 10, in the container according to the present invention, each top corner portion of the container body 31 further includes a first top corner fitting 313, a second top corner fitting 314 and a third top corner fitting 315. The first top corner fitting 313 and the first bottom corner fitting 311 are located in the same vertical hne, and the second top corner fitting 314 and the second bottom corner fitting 322 are located in the same vertical hne, and the third top corner fitting 315 is disposed at an outer side of the second top corner fitting 314.
    In this embodiment, the distance between the two first top corner fittings 313 at the same side of the container body 31 is equal to the center distance L2 between two first bottom corner fittings 311 at the same side, thereby ensuring that, when another first specification standard case is heaped on the top face of the second specification standard case 3, the bottom corner fittings of the first specification standard case can fully correspond to the two first top corner fittings 313 of the second specification standard case, or when another second specification standard case is heaped on the top face of the second specification standard case, the first bottom corner fittings thereof can fully correspond to the two first top corner fittings 313 of the lower second specification standard case.
    In this embodiment, the distance between the first top corner fitting 313 and the second top corner fitting 314 at the same side of the container body 31 is equal to the center distance LI between the first bottom corner fitting 311 and the second bottom corner fitting 322 at the same side, thereby ensuring that, when another second specification standard case is heaped on the top face of the second specification standard case, the second bottom corner fittings connected to the buffer device 321 can fully correspond to the two first top corner fittings 313 of the lower second specification standard case, so as to provide an accurate landing point for the buffer device.
    In this embodiment, the third top corner fitting 315 is disposed at the outer side of the second top corner fitting 314, so as to facihtate the lifting operation of the container 3.
    Therefore, as the disposition of the top corner fittings and the bottom corner fittings (collectively referred to as "corner fittings") of the container 3 complies with the ISO standards, which ensures that the container 3 not only can be placed in a seagoing ship deck area for carrying the first specification standard cases complying with the ISO standards, but also can be heaped on a top-face area formed by at least three first specification standard cases arranged side by side. Moreover, as the top corner portions of the container 3 are also disposed with top corner fittings complying with the ISO standards, the heaping (stacking or stowing) of the containers can be implemented, thereby greatly improving the effective utihzation of the transport space. Therefore, the number of the containers capable of being loaded in the same space is relatively increased in a transport or moving period. Especially for the precious loading space of the seagoing ships, it is more significant to improve the utihzation of the effective space, thereby greatly reducing costs in the transport, storage, and logistics management.
    As mentioned above, in the container according to the present invention, the positioning buffer is disposed at each bottom corner portion of the container body. When the container is loaded to or unloaded from the seagoing container trailer or a container ship by using a crane, the impact force resulted from collision can be efficiently reduced, thereby ensuring the safety and stability of the goods in the container. Moreover, as the floor and the side walls of the container body are all disposed with bundling rings and bundling rails for the bundling belts to vertically and horizontally bind the goods in the container, the goods in the container are internally fixed, thereby further avoiding damage to the goods in the container during the loading/unloading operations.
    In the container according to the present invention, the bottom corner fittings and the top corner fittings are disposed on each of the bottom corner portions and each of the top corner portions of the container body, so that the containers can be stacked or stowed. Moreover, as the disposition of the corner fittings of the container in the present invention comphes with the ISO standards, the container of the present invention and containers of other specifications can be stacked or stowed together, thereby improving effective utihzation of the transport space, reducing the transport and storage costs, and particularly possessing a higher industrial application value for the seagoing ships with limited and precious transport space.
    The container of the present invention is a totally closed container, thereby overcoming the defect in the prior art that the loading/unloading schedule for the flat container is easily affected by the weather, and solving such problems existing in the prior art as waste of wood resources, high cost in waste processing and environmental pollution resulted from the wood packing manner, and effectively reducing the transport and loading/unloading costs. Therefore, the present invention effectively overcomes the disadvantages of the prior art, and has a high industrial application value.
    The description of the above embodiments is only to illustrate the principle and effect of the present invention, but is not intended to limit the present invention. Any persons skilled in the art can make modification or variation to the above embodiments without departing from the spirit and scope of the present invention. Any equivalent modification and change made by persons with ordinary skill in the art without departing from the spirit and technical thought disclosed in the present invention shall all fall within the scope of claims of the present invention.
