Description

Technical Field

[0001] The invention relates to the field of containers, in particular to a container and a loading process method thereof. Background Art

[0002] With the development of social economy, containers are becoming more and more popular among the public. Containers have significant advantages in terms of cost, construction efficiency and solution platform. They are now widely used in the transportation of goods and can achieve multimodal transport in ships, ports, routes, roads, bridges, tunnels and transfer stations around the world. Conventional containers are generally equipped with end doors at one end. After the end doors are pivoted outward and opened, cargo can be loaded and unloaded from the end doors.

[0003] However, as container transportation becomes more standardized and popularized, special goods can also be transported in standard containers. However, some special goods have higher requirements for the transportation environment. For example, some special goods have requirements for the moisture content, vacuum degree, and cleanliness in the container, and the structure and sealing of general standard containers cannot guarantee the transportation of such special goods.

[0004] Therefore, a new, more airtight container and its loading process must be designed. Summary of the invention

[0005] In order to solve the above problems, the present invention proposes a container, comprising a box body and a door body opened and closed on the box body, the door body comprising a door frame and a door panel, the box body comprising a box panel; a door opening is opened on the box panel or the door panel, and the container further comprises a manhole assembly adapted to the door opening; the manhole assembly comprises a manhole cover that can cover the door opening and a locking member for locking the manhole cover, and when the locking member is in a locked state, the manhole cover is locked and sealed toward the outside of the container;

[0006] A gap is formed between the door frame and the door plate, and the container further comprises a first sealing member clamped in the gap and a second sealing member arranged on the inner surface of the container and capable of sealing the gap.

[0007] As a further improvement of the present invention, an inflation valve is provided on the box panel or the door panel.

[0008] As a further improvement of the present invention, during the cargo transportation process in the container, the air pressure in the container is greater than a standard atmospheric pressure.

[0009] As a further improvement of the present invention, the door body is arranged at the end of the container, the door opening is opened on the door panel, and the manhole assembly is arranged on the door body.

[0010] As a further improvement of the present invention, the manhole assembly also includes a manhole frame, which is fixed on the door panel and corresponds to the door opening. The manhole cover is hinged to one side of the manhole frame and can be pivoted inward to open the door opening or pivoted outward to close the door opening; in the locked state, the locking piece is connected between the manhole frame and the manhole cover.

[0011] As a further improvement of the present invention, the manhole assembly further comprises a track, which is fixed to the inner side of the door panel and corresponds to the door opening, and the manhole cover can slide along the track to open or close the door opening.

[0012] As a further improvement of the present invention, the cross section of the second sealing member is L-shaped and is a disposable sealing strip.

[0013] In order to solve the above problems, the present invention proposes a container loading process method, the loading process method comprising:

[0014] Open the door panel and load the goods into the container;

[0015] Close and lock the door panel;

[0016] Open the manhole cover and enter the box through the door opening;

[0017] A second sealing member is attached to the gap between the door frame and the door panel of the container;

[0018] After passing through the door opening and reaching outside the box, close and lock the manhole cover.

[0019] As a further improvement of the present invention, the step of "closing and locking the manhole cover" includes:

[0020] Open the inflation valve;

[0021] Fill the container with protective gas so that the air pressure inside the container is greater than one standard atmospheric pressure;

[0022] Close the inflation valve.

[0023] As a further improvement of the present invention, the protective gas is nitrogen.

[0024] Beneficial effects of the present invention: Therefore, since a gap is formed between the door frame and the door panel of the container, the gap can be sealed by the first sealing member. Moreover, after the door panel is closed on the door frame, since a door opening is provided, the operator can open the manhole cover and enter the container body through the door opening, and a second sealing member is provided on the inner surface of the container to seal the gap, thereby further improving the overall sealing of the container. In addition, since the locking member of the manhole assembly is provided on the outside of the manhole cover, after the operator has provided the second sealing member, he leaves the container from the door opening and locks the manhole cover through the locking member, thereby realizing the locking and sealing of the container from the outside.

[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] In addition, repeated reference numerals or symbols may be used in different embodiments. These repetitions are only for the purpose of simply and clearly describing the present invention, and do not represent any correlation between the different embodiments or structures discussed.

[0031] In various drawings of the present application, for the convenience of illustration, some sizes of structures or parts are exaggerated relative to other structures or parts, and thus, are only used to illustrate the basic structure of the subject matter of the present application.

[0032] like Figures 1 to 4 As shown, the present invention provides a container 100 and a loading method thereof. Figure 1As shown, the container 100 includes a box body 10 and a door body 20 that is opened and closed on the box body 10, the door body 20 includes a door frame 2 and a door panel 3, and the box body 10 includes a box panel 1. In this specific embodiment, the door body 20 is arranged at the end of the box body 10, that is, the door body 20 is an end door. Of course, if the door body 20 is arranged on the side or upper part of the container 100, the purpose of the present invention can also be achieved.

[0033] A door opening is formed on the box panel 1 or the door panel 3, and the container 100 further comprises a manhole assembly adapted to the door opening; the manhole assembly comprises a manhole cover 4 that can cover the door opening and a locking member 5 for locking the manhole cover 4, and when the locking member 5 is in a locked state, the manhole cover 4 is locked and sealed toward the outside of the box body 10 of the container 100;

[0034] like Figure 4 As shown, a gap 21 is formed between the door frame 2 and the door panel 3 , and the container 100 further includes a first sealing member 22 sandwiched in the gap 21 and a second sealing member 23 disposed on the inner surface of the container 100 and capable of sealing the gap 21 .

[0035] Therefore, since the gap 21 is formed between the door frame 2 and the door panel 3 of the container 100, the gap 21 can be sealed by the first sealing member 22. Moreover, after the door panel 3 is closed on the door frame 2, since a door opening is provided, the operator can open the manhole cover 4 and enter the box body 10 of the container 100 through the door opening, and set a second sealing member 23 on the inner surface of the container 100 to seal the gap 21, thereby further improving the overall sealing of the container 100. In addition, since the locking member 5 of the manhole assembly is set on the outside of the manhole cover 4, after the operator sets the second sealing member 23, he leaves the container 100 from the door opening and locks the manhole cover 4 through the locking member 5, thereby realizing the locking and sealing of the manhole cover 4 from the outside.

[0036] Furthermore, an inflation valve (not shown) is provided on the box panel 1 or the door panel 3. The inflation valve can be opened to inflate the container 100. Moreover, during the transportation of goods in the container 100, the air pressure in the container 100 is greater than one standard atmospheric pressure. It is known that, under normal circumstances, the air pressure outside the container 100 is about one standard atmospheric pressure, and the air pressure in the container 100 is greater than one standard atmospheric pressure by inflating the container 100 through the inflation valve, thereby ensuring that the airtightness of the container 100 is stronger and the locking and sealing effect at the manhole cover 4 is better. In addition, the air pressure in the container 100 is greater than the air pressure outside the container body 10 of the container 100, so that the manhole cover 4 can be pressed outward by force, and during the transportation process, even if a collision occurs, the container 100 will not leak.

[0037] As described above, in the present invention, the door body 20 is arranged at the end of the container 100, that is, the door body 20 is actually the end door of the container 100, the door opening is opened on the door panel 3, and the manhole assembly is also correspondingly arranged on the door body 20. Of course, if the door opening and the manhole assembly are both arranged on the box panel 1, the purpose of the present invention can also be achieved.

[0038] Furthermore, as described above, the manhole assembly includes the manhole cover 4 and the locking member 5, and the locking member 5 is used to lock the manhole cover 4. Of course, the manhole assembly also includes other structures to cooperate with the manhole cover 4 and the locking member 5. In the following, two specific implementations of the manhole assembly are provided in the present invention.

[0039] Specifically, Figure 3 and 4 As shown in the first specific embodiment of the present invention, the manhole assembly also includes a manhole frame 6, which is fixed on the door panel 3 and corresponds to the door opening. The manhole cover 4 is hinged to one side of the manhole frame 6 and can be pivoted into the container 100 to open the door opening or pivoted outward to close the door opening; in the locked state, the locking member 5 is connected between the manhole frame 6 and the manhole cover 4.

[0040] Obviously, the manhole frame 6 is fixed to the inner side of the door panel 3, and the range of the manhole frame 6 is larger than the range of the door opening, so that the manhole cover 4 can gradually cover the door opening when it is pivoted outward. In addition, in the locked state, the locking member 5 is connected between the manhole frame 6 and the manhole cover 4 to lock the manhole cover 4 in the manhole frame 6. Figure 4 As shown in , the manhole assembly further includes a third sealing member 41, which is disposed on the manhole cover 4 to seal between the manhole cover 4 and the manhole frame 6 when the manhole cover 4 is closed. As described above, the air pressure in the container 100 is greater than the air pressure outside the container body 100, so that the manhole cover 4 can be more tightly pressed against the third sealing member 41, and the sealing effect is better.

[0041] Alternatively, in a second specific embodiment of the present invention, the manhole assembly further comprises a track (not shown), which is fixed to the inner side of the door panel 3 and corresponds to the door opening, and the manhole cover 4 can slide parallel to the track to open or close the door opening.

[0042] The manhole cover 4 can slide along the track and can open or close the door opening during the sliding process. Obviously, the tracks are arranged in pairs and can extend along the upper and lower sides of the door opening respectively. In the locked state, the locking member 5 can lock the manhole cover 4 on the track or the door panel 3.

[0043] In addition, the first sealing member 22 is a hollow rubber strip and is sandwiched between the door frame 2 and the door panel 3. The second sealing member 23 has an L-shaped cross section and is a disposable sealing rubber strip. Figure 4 As shown in the figure, one side of the second seal 23 is attached to the inner surface of the door frame 2, and the other side is attached to the inner surface of the door panel 3. The second seal 23 is disposable, so after the operator closes the door body 20 and enters the container 100 through the door opening, the second seal 23 can be attached to the door frame 2 and the door panel 3 to enhance the sealing performance. After arriving at the unloading location, the operator can continue to enter the container 100 through the door opening and tear off the second seal 23 to facilitate opening the door body 20. Of course, the door body 20 can also be directly opened to damage the second seal 23. The second seal 23 is detachable and is an adhesive sealing strip, aluminum foil, etc.

[0044] Alternatively, the second sealing member 23 may be fixed to the door frame 2 and the door panel 3 by other means such as snaps, pressure plates, etc., so that the second sealing member 23 may not be a one-time setting but may be reused.

[0045] The present invention also provides a loading process method, which comprises:

[0046] Open the door panel 3 and load the goods into the box body 10 of the container 100;

[0047] Close and lock the door panel 3;

[0048] Open the manhole cover 4 and enter the box body 10 through the door opening;

[0049] A second sealing member 23 is attached to the gap 21 between the door frame 2 and the door panel 3 of the container 100;

[0050] After passing through the door opening and reaching the outside of the box body 10, the manhole cover 4 is closed and locked.

[0051] Corresponding to the structure of the container 100, through the above method, after the door body 20 has been closed, the operator can still enter the box body 10 by opening the manhole cover 4 and passing through the door opening, and further seal the gap 21 between the door body 20 and the door frame 2, thereby enhancing the sealing of the container 100. In addition, after the second sealing member 23 is set, the operator can still pass through the door opening, close the manhole cover 4 to cover the door opening, and lock the manhole cover 4 through the locking member 5 to ensure the sealing between the manhole cover 4 and the door opening.

[0052] Further, the step of "closing and locking the manhole cover 4" includes:

[0053] Open the inflation valve;

[0054] Filling the container 100 with protective gas so that the air pressure in the container 100 is greater than one standard atmospheric pressure;

[0055] Close the inflation valve.

[0056] Also corresponding to the above, after the step of "closing and locking the manhole cover 4", the operator opens the inflation valve and fills the protective gas into the container 100. After the air pressure in the container 100 is greater than one standard atmospheric pressure, the inflation valve is closed. Thus, the container 100 always maintains a positive pressure state, which can further ensure the sealing between the manhole cover 4 and the door opening, and ensure that the gas, dust, etc. outside the container 100 will not enter the container 100, so that the water content and cleanliness in the container 100 are kept constant.

[0057] Specifically, the protective gas is nitrogen. Of course, if the protective gas is other inert gases, the purpose of the present invention can also be achieved. Filling the container 100 with inert gas can maintain the stability of the chemical state of the goods in the container 100, thereby further improving the stability of the transportation of goods in the container 100.

[0058] In summary, the present invention provides a container 100 and a loading method thereof, so that after the door panel 3 is closed on the door frame 2, since a door opening is provided, the operator can open the manhole cover 4 and enter the box body 10 of the container 100 through the door opening, and set a second sealing member 23 on the inner surface of the container 100 to seal the gap 21, thereby further improving the overall sealing of the container 100. In addition, since the locking member 5 of the manhole assembly is set on the outside of the manhole cover 4, after the operator sets the second sealing member 23, he leaves the container 100 from the door opening, and locks the manhole cover 4 through the locking member 5, thereby realizing the locking and sealing of the container 100 from the outside.

[0059] In addition, the container 100 is provided with an inflation valve, and after the manhole cover 4 is closed and locked, the inflation valve is opened to fill the container 100 with protective gas, so that the air pressure in the container 100 is greater than one standard atmospheric pressure. Therefore, during transportation, the gas, dust, etc. outside the container 100 cannot enter the container 100, thereby maintaining the stability of the internal environment of the container 100, ensuring the humidity, cleanliness, etc. in the container 100, so as to meet the transportation requirements of specific goods. In addition, the protective gas is nitrogen, which can maintain the stability of the chemical state of the goods in the container 100 and further improve the stability of cargo transportation.
