[0057] Hereinafter, specific embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. These drawings illustrate representative embodiments of the present disclosure and do not limit the present disclosure.

[0058] As an international general transportation and logistics tool for multimodal transport, containers are used in increasingly wider areas and involve more and more industries.

[0059] As shown in FIG. 1 to FIG. 19 , an embodiment of the present disclosure provides a container 100 . The container 100 includes a top plate 111 and a top cover 112 .

[0060] The top plate 111 is provided with a feed port 101, and a support plate 123 is provided at the feed port 101 (see Figures 2 and 3). A top cover 112 can be connected to the top plate 111 to close the feed port 101. Referring to Figures 1 and 18, in the example disclosed herein, the feed port 101 is a square port, and the top cover 112 is configured as a matching square structure.

[0061] The top cover 112 includes a cover plate 112a and a back beam 112b, and the back beam 112b is disposed on the inner side 181 of the cover plate 112a. The inner side 181 of the cover plate 112a may refer to the side facing the interior of the container 100 when the top cover 112 is covered on the roof plate 111.

[0062] The back beam 112b is connected to the cover plate 112a and forms a mounting groove 121 with the cover plate 112a. The mounting groove 121 can be used to install an elastic seal 122. Specifically, the mounting groove 121 is located at the circumferential edge 182 of the top cover 112. When the top cover 112 is covered on the top plate 111, the support plate 123 at least partially extends into the mounting groove 121 and cooperates with the elastic seal 122 to seal the feed port 101. It will be understood that the location of the mounting groove 121 corresponds to the location of the support plate 123.

[0063] The circumferential edge 183 of the cover plate 112a is configured to bend toward the back beam 112b to form the outer sidewall 121a of the mounting groove 121. The back beam 112b is formed with the inner sidewall 121b of the mounting groove 121. Thus, when the back beam 112b is connected to the cover plate 112a, the connection location is located on the inner side of the cover plate 112a. On the one hand, the bent portion of the cover plate 112a (the outer sidewall 121a of the mounting groove 121) effectively protects the connection location between the top cover 112 and the support plate 123, improving the sealing effect. On the other hand, when the back beam 112b is welded to the cover plate 112a to close the top cover 112, the weld between the back beam 112b and the cover plate 112a is also located on the inner side of the container 100 and is not exposed on the outside of the container 100, reducing the risk of rust and water leakage at the weld location.

[0064] The bottom wall of the mounting groove 121 can be formed by a portion of the cover plate 112a, or can be formed by the back beam 112b and the cover plate 112a. Referring to the embodiment shown in FIG2 , the bottom wall 121c of the mounting groove 121 is formed by a portion of the back beam 112b.

[0065] When the feed port 101 of the container 100 is arranged on the top plate 111 , the feed port 101 extends vertically. When the top cover 112 closes the feed port 101 , the installation groove 121 faces vertically downward, making it inconvenient to install the elastic seal 122 .

[0066] To better secure the elastic seal 122, at least one of the outer sidewall 121a and the inner sidewall 121b can be configured to be inclined toward the interior of the mounting groove 121. This allows the width of the mounting groove 121 at the notch to be smaller than the width at the bottom. Since the elastic seal 122 is elastic, it can be squeezed and installed into the mounting groove 121 through the notch. Furthermore, the elastic seal 122 can recover from its squeezed state (towards its natural state) within the mounting groove 121, thereby pressing against the inner wall and bottom wall 121c of the mounting groove 121, making it difficult to escape from the notch. This ensures that the elastic seal 122 is stably retained within the mounting groove 121.

[0067] 3 , in one embodiment of the present disclosure, the outer side wall 121 a is configured to be inclined toward the inside of the mounting groove 121 .

[0068] Optionally, the angle α between the outer wall 121a and the inner wall 121b satisfies the following: 1° ≤ α ≤ 10°. As shown in Figure 3, the inner wall 121b is generally configured to be perpendicular to the cover plate 112a. When the angle between the outer wall 121a and the horizontal plane is 80° ≤ Q ≤ 89°, it can effectively restrict the elastic seal 122 within the mounting groove 121 and prevent the elastic seal 122 from falling out of the mounting groove 121. In this embodiment, α is 2°.

[0069] 5 , both the outer sidewall 121a and the inner sidewall 121b of the mounting groove 121 are inclined inwardly. It should be noted that “inwardly” as described herein may refer to the middle of the mounting groove 121 in the width direction D2.

[0070] Optionally, at least one of the outer sidewall 121a and the inner sidewall 121b may be configured to at least partially protrude into the mounting groove 121, thereby reducing the width of a local area (the protruding portion) of the mounting groove 121, thereby also preventing the elastic seal 122 from falling out of the mounting groove 121. This protects the elastic seal 122 in the mounting groove 121 and avoids frequent replacement of the elastic seal 122.

[0071] With reference to Figure 4, with reference to another embodiment of the present disclosure, the side wall (inner wall 121b and / or outer wall 121a) of the mounting groove 121 can be partially protruded into the mounting groove 121 to form a first bend portion 121d. Thus, the elastic seal 122 can be restricted from escaping from the mounting groove by the first bend portion 121d. Along the depth direction of the mounting groove 121, the first bend portion 121d is spaced apart from the bottom wall 121c of the mounting groove 121. Thus, the elastic seal 122 can be clamped and installed between the first bend portion 121d and the bottom wall 121c. As shown in Figure 4 (a), the inner wall 121b of the mounting groove 121 is constructed to partially protrude into the mounting groove 121 to form the first bend portion 121d, and the first bend portion 121d is located in the middle position of the inner wall 121b along the depth direction of the mounting groove 121.

[0072] As shown in FIG4( b ), the outer side wall 121 a is formed with a first bent portion 121 d, and the first bent portion 121 d is located at the notch position of the mounting groove 121. It is understood that after the elastic seal 122 is installed, the outer side wall 121 a can be bent at the notch position toward the mounting groove 121 to form the first bent portion 121 d.

[0073] The bending angle of the first bend portion 121d ranges from 1° to 90°. For example, the bending angle of the first bend portion 121d can be 30°, 45°, 60°, 75°, or 90°. As shown by the dotted line in FIG. (b), the bending angle of the first bend portion 121d is an acute angle. As shown by the solid line in FIG. (b), the bending angle of the first bend portion 121d is approximately 90°. This can better prevent the elastic seal 122 from falling out of the mounting groove 121. This serves to protect the elastic seal 122 in the mounting groove 121.

[0074] Optionally, the bottom wall 121c of the mounting groove 121 is also formed by bending the back beam 112b. That is, the back beam 112b forms the bottom wall 121c and inner side wall 121b of the mounting groove 121. The bottom wall 121c and inner side wall 121b are connected by a third bent portion 121e. Referring to Figures 2 and 3, the bottom wall is positioned in contact with the inner surface of the cover plate 112a. For example, the bottom wall 121c can be welded to the inner surface of the cover plate 112a.

[0075] It should be noted that the back beam 112b mentioned above specifically refers to a beam structure disposed on the inner side of the cover plate 112a, at the circumferential edge thereof, and forming a mounting groove 121 together with the cover plate 112a. In this embodiment, the feed port 101 is a square port, and the top cover 112 is a square. Correspondingly, the back beam 112b includes two horizontal beams and two vertical beams disposed on the inner side of the square cover plate 112a. The two horizontal beams and the two vertical beams are connected to form a square frame (see the dotted line portion around the top cover 112 in FIG. 18 ).

[0076] The back beam 112b can be made of a profile having at least one bent portion 185. For example, the back beam 112b can be made of a profile such as an I-beam, a channel steel, a square tube, or an angle steel, which can improve the structural strength of the top cover 112.

[0077] In this embodiment, the back beam 112b is constructed by bending a plate. Referring to Figures 2 and 3, the back beam 112b includes three bends 185, and the bend angle of the bend 185 is approximately 90 degrees. Specifically, the back beam 112b is formed with a bottom wall 121c and an inner side wall 121b of the mounting groove 121. The bottom wall 121c is attached to the inner surface of the cover plate 112a and fixed to the cover plate 112a. The bottom wall 121c and the inner side wall 121b are connected by a third bend 121e. The inner side wall 121b of the mounting groove 121 is bent 90 degrees toward the outside of the mounting groove 121 at the notch position, and then bent again 90 degrees toward the cover plate 112a after extending a predetermined length, extending to abut the inner surface of the cover plate 112a and fixed to the cover plate 112a (see Figures 2 and 3). Thus, deformation of the inner sidewall 121 b of the mounting groove 121 can be reduced, and the structural strength of the top cover 112 can be improved.

[0078] In practice, in order to improve the structural strength of the top cover 112, a reinforcing beam 112c may be provided on the inner side of the cover plate 112a, and the reinforcing beam 112c is connected to the cover plate 112a and the back beam 112b. In the embodiment shown in FIG18, the top cover 112 includes a plurality of reinforcing beams 112c.

[0079] In addition, as the container 100 is used, the support plate 123 at the circumferential edge of the feed port 101 will come into contact with the mounting groove 121 , and the support plate 123 may easily damage the elastic sealing member 122 in the mounting groove 121 .

[0080] Optionally, the edge (outer edge) of the support plate 123 can be flipped and bent, so that the outer edge of the support plate 123 is flipped to a position away from the elastic seal 122, thereby preventing the edge of the support plate 123 from directly contacting the elastic seal 122 in the mounting groove 121, thereby reducing damage to the elastic seal 122. As shown in Figure 2, when the support plate 123 is engaged with the elastic seal 122, the flipped and bent outer edge of the support plate 123 extends downward and exceeds the lower surface of the elastic seal 122, preventing the outer edge of the support plate 123 at the feed port 101 from cutting the elastic seal 122, extending the service life of the elastic seal 122, and enhancing the sealing effect.

[0081] With reference to Figure 2, according to one embodiment of the present disclosure, the upper edge of the support plate 123 is bent outward and downward, and a second bent portion 123a is formed. When the top cover 112 is covered on the top plate 111, the second bent portion 123a is used to abut and cooperate with the elastic seal 122. In the embodiment shown in Figure 2, the support plate 123 is a metal plate or a steel plate, which can better support the top cover 112. The surface of the second bent portion 123a formed after the support plate 123 is turned over and bent is a smooth curved surface, which can make the contact surface of the support plate 123 and the elastic seal 122 fit better, and the sealing effect is better without damaging the elastic seal 122. Optionally, the angle β of the support plate 123 at the second bent portion 123a is less than 90°.

[0082] The elastic seal 122 may be made of an elastic material with a relatively large elastic coefficient. Referring to FIG2 , the container 100 of the present disclosure may further include an elastic seal 122 , which is disposed in the installation groove 121 along the extension direction of the installation groove 121 .

[0083] When the top cover 112 is covered on the top plate 111, the elastic deformation of the elastic seal 122 along the depth direction of the installation groove 121 (ie, the height direction D3 of the container 100) reaches a predetermined range, which can ensure good sealing performance.

[0084] Referring to Figure 6, according to an example of the present disclosure, the elastic seal 122 is constructed as a hollow column. It can be understood that the hollow design of the elastic seal 122 can not only ensure the sealing effect, but also effectively reduce the operating force that needs to be applied to the top cover 112 when closing the top cover 112. In this embodiment, the elastic seal 122 can be a sealing strip. In Figure 6, the through-hole structure in the middle of the elastic seal 122 has a dimension L in the depth direction of the mounting groove 121, and when the support plate 123 and the elastic seal 122 are in abutment with each other, it is ensured that the deformation of the elastic seal 122 is at least L (see the example in Figure 6).

[0085] In other embodiments of the present disclosure, the elastic sealing member 122 may be a solid columnar structure to increase the service life of the elastic sealing member 122. Those skilled in the art may make a selection based on actual needs.

[0086] 1 , the top cover 112 is further provided with a handle 116 , which makes it more convenient for a worker to operate to open / close the top cover 112 .

[0087] The top cover 112 can be pivotally connected to the top plate 111 via a shaft 189. Referring to Figures 1 and 7 to 11, the top cover 112 is connected to the top plate 111 via a hinge 113, and the top cover 112 can pivot between an open position for opening the feed port 101 and a closed position for sealing the feed port 101.

[0088] In the embodiment shown in Figure 1 , two top covers 112 are provided on the top of the container 100, spaced apart along the length direction D1. The rotation axis 189 of each top cover 112 is configured to extend generally along the length direction D1 of the container 100. The two top covers 112 open and close in the same direction (the rotation axis 189 of each top cover 112 is located on the same side in the width direction D2).

[0089] A damping member 114 is also connected between the top cover 112 and the top plate 111. As the top cover 112 pivots between the open and closed positions, the damping member 114 generates a damping force to slow the pivoting speed of the top cover 112. This effectively reduces the operator's operating force when opening and closing the top cover 112, and also reduces vibration during the opening and closing process, preventing the top cover 112 from colliding with the box body and causing damage (preventing violent collisions between the top cover 112 and the top plate 111). In this embodiment, the damping member 114 is a torsion spring.

[0090] A door lock 115 is further provided between the top cover 112 and the top plate 111 . The door lock 115 may be a lock rod and lock seat assembly for locking the top cover 112 in a closed position.

[0091] The container 100 further includes a locking device 192 for locking the top cover 112 in the open position. Referring to the embodiment shown in Figures 8 to 11 , the open position specifically refers to the fully open position of the top cover 112. Referring to Figure 8 , in this open position, the cover plate 112a of the top cover 112 faces the roof plate 111 of the container 100.

[0092] The locking device 192 includes a connecting hook 118 and a connecting ring 117. The connecting hook 118 is provided to one of the top cover 112 and the top plate 111, and the connecting ring 117 is provided to the other of the top cover 112 and the top plate 111. In this embodiment, the connecting hook 118 is provided to the top cover 112, and the connecting ring 117 is provided to the top plate 111.

[0093] The connecting ring 117 can pivot between a locked position and an unlocked position. When the top cover 112 is pivoted to the open position, the connecting ring 117 in the locked position can cooperate with the connecting hook 118 to keep the top cover 112 in the open position and prevent the top cover 112 from pivoting to the closed position.

[0094] Specifically, with reference to FIG9 , with the top cover 112 in the open position and the connecting ring 117 positioned outside the top cover 112, and with the connecting ring 117 in the unlocked position, the connecting ring 117 can be operated to pivot toward the top cover 112 so that the connecting hook 118 at least partially passes through the connecting ring 117 (see FIG10 and FIG11 ). In FIG10 and FIG11 , the connecting ring 117 is in the locked position. With reference to FIG11 , at this point, the connecting hook 118 partially passes through the connecting ring 117, and the top cover 112 in the open position cannot pivot toward the closed position.

[0095] 1 , 8 and 9 , in this embodiment, the pivot direction of the connecting ring 117 intersects with the pivot direction of the top cover 112 , which can achieve better locking of the top cover 112 and prevent the top cover 112 from shaking.

[0096] In the embodiment shown in FIG18 , the top of the container 100 is provided with two top covers 112, spaced apart along the longitudinal direction D1. The rotation axis 189 of each top cover 112 is configured to extend generally along the width direction D2 of the container 100. The two top covers 112 open and close in opposite directions (the rotation axis 189 of each top cover 112 is located on different sides along the longitudinal direction D1). The top covers 112 shown in FIG18 are similarly connected to the top panel 111 using hinges 113 and dampers 114.

[0097] The damping member 114 mentioned above can effectively reduce the operating force required to open and close the top cover 112. For details, see Figures 1, 7, 8, and 21. In Figures 1 and 7, the top cover 112 is in the closed position. At this point, the damping member 114 is configured to apply a force to the top cover 112, causing it to move toward the open position. This force acts as a force assisting the opening operation of the top cover 112, thereby reducing the operating force required to open the top cover 112. In Figures 8 and 21, the top cover 112 is in the open position. At this point, the damping member 114 is configured to apply a force to the top cover 112, causing it to move toward the closed position. This force acts as a force assisting the closing operation of the top cover 112, thereby reducing the operating force required to close the top cover 112. Therefore, the damping member 114 can be referred to as a force-applying member.

[0098] In addition to the closed and open positions described above, the top cover 112 may also have a transition position between the open and closed positions, as shown in FIG20 . In this transition position, the force applied by the force-applying member to the top cover 112 does not exceed a preset value. The preset value may range from 0 to 10N, for example, any suitable value such as 0N, 2N, 4N, 6N, 8N, or 10N. When the force applied by the force-applying member to the top cover 112 is within the preset range, the force-applying member will not hinder or promote the opening or closing movement of the top cover 112. In other words, when the force applied by the force-applying member to the top cover 112 is within the preset range, the force-applying member is in a non-operating state and does not apply an effective force to the top cover 112 to assist in the opening or closing operation of the top cover 112. Preferably, in the transition position, the force applied by the force-applying member to the top cover 112 is zero.

[0099] In the embodiment shown in Figure 20, when the top cover 112 is in the transition position, the top cover 112 is in a vertical or substantially vertical state, that is, the top cover 112 is vertical or substantially vertical relative to the top plate 111. However, the transition position of the top cover 112 is not limited to the position shown in Figure 20.

[0100] In the embodiments shown in Figures 7, 20 and 21, the force-applying member is configured as a torsion spring. When the top cover 112 is in the transition position shown in Figure 20, the torsion spring is in a free (initial) state without elastic deformation, and does not apply a force to the top cover 112, or the torsion spring has a small elastic deformation, and the force applied to the top cover 112 does not exceed the above-mentioned preset value. In the closed position shown in Figure 7, the torsion spring is in a stressed state and has a large elastic deformation, which will generate a restoring force to recover toward the free state shown in Figure 20 or the state with small elastic deformation. This restoring force can be applied to the top cover 112 as a booster during the opening of the top cover 112 to facilitate the opening operation of the top cover 112. That is, in the closed position shown in Figure 7, the torsion spring is configured to apply a force to the top cover 112 to move it toward the open position. In the open position shown in FIG21 , the torsion spring is in a stressed state and has a large elastic deformation, generating a restoring force toward the free state or the state with a small elastic deformation shown in FIG20 . This restoring force can be applied to the top cover 112 during the closing of the top cover 112 as an assist force, thereby facilitating the closing operation of the top cover 112. That is, in the open position shown in FIG21 , the torsion spring is configured to apply a force to the top cover 112 to cause it to move toward the closed position.

[0101] However, if needed and / or desired, the force-applying member may also be constructed as a device or element other than a torsion spring, as long as it can be constructed to apply a force to the top cover 112 to move it toward the closed position when the top cover 112 is in the open position, and to apply a force to the top cover 112 to move it toward the open position when the top cover 112 is in the closed position.

[0102] The body of the container 100 is roughly a rectangular parallelepiped structure, including a top plate 111 and a bottom frame 190 spaced apart along the height direction D3, a front end and a rear end spaced apart along the length direction D1, and a left side and a right side spaced apart along the width direction D2. The doors of the container 100 can be set at the front end, the rear end, the left side, and the right side. As shown in Figures 12 and 13, the container 100 in this embodiment is a bulk container 100, and the container 100 also includes wall panels 131. The wall panels 131 include wall panels 131 (end walls) located at the front and rear ends of the container 100 and wall panels 131 (side walls) on the left and right sides. The wall panels 131 extend along the height direction D3 of the container 100.

[0103] Referring to Figure 12 , the wall panel 131 is a corrugated sheet with raised portions 131a extending from the interior of the container 100 toward the exterior. (The corrugated sheet also has recessed portions extending from the exterior of the container 100 toward the interior 103 of the container 100, with the recessed portions and raised portions 131a alternating between them.) An anti-accumulation plate 136 is also provided within the container 100. The anti-accumulation plate 136 is positioned at the bottom end 187 of the raised portion 131a along the height direction D3 and is inclined relative to the height direction D3. As shown in Figure 12 , the anti-accumulation plate 136 is inclined toward the exterior of the container 100, and the distance (height difference) between the top surface 188 of the anti-accumulation plate 136 and the top surface 191 of the container 100 chassis 190 decreases from the exterior of the container 100 toward the interior. It should be noted that when the anti-accumulation plate 136 is connected to the raised portion 131a, its shape conforms to that of the raised portion 131a. This eliminates dead corners within the container and prevents cargo from remaining. Optionally, guide plates can be installed at the corner posts 119 of the container 100. These guide plates can be arranged at an angle relative to the wall panels 131 and extend along the height direction D3 to prevent cargo from remaining at the corner posts 119.

[0104] In this embodiment, the container 100 may further include a ventilation assembly 130, which is attached to a wall panel 131. Referring to Figures 13 to 15 , the wall panel 131 is further provided with ventilation holes 132 near the top panel 111, and the ventilation assembly 130 and the ventilation holes 132 are in communication. The ventilation holes 132 increase the ventilation area and prevent negative pressure from forming within the container 100 during unloading. In this embodiment, the ventilation holes 132 are provided on one end wall of the container 100 (see Figure 13 ) and are located in a recessed portion (see Figure 15 ).

[0105] The ventilation assembly 130 may include an orifice plate 135, a mounting plate 133, and a baffle 134. As shown in Figures 14 and 15, the orifice plate 135 is located outside the wall panel 131, covering the ventilation hole 132 and connected to the wall panel 131. As shown in Figure 15, the mounting plate 133 is located near the ventilation hole 132, connected to the wall panel 131, and extends toward the outside of the container 100. The mounting plate 133 may be welded to the wall panel 131. The baffle 134 is located outside the orifice plate 135 and connected to the mounting plate 133. The baffle 134 and orifice plate 135 are spaced apart along the axial direction of the ventilation hole 132. Thus, the baffle 134, the support plate 123, and the wall panel 131 enclose a channel structure at the location of the recess. During unloading of the container 100, the interior and exterior of the container can communicate through this channel structure, the orifice plate 135, and the ventilation hole 132.

[0106] In this embodiment, ventilation hole 132 is located at the upper front end of container 100 and has a diameter of 60 mm. A discharge door 141 (described below) is located at the rear end of container 100. A perforated plate 135 is positioned outside ventilation hole 132, with 3 mm diameter air holes evenly distributed on the plate.

[0107] In this embodiment, the baffle 134 does not extend beyond the outer contour of the container 100, and has a compact and more beautiful structure. It is not easy to bump into, and meets the transportation requirements of the container 100. The baffle 134 can prevent rainwater, dust and other debris in the environment from entering the container 100 through the perforated plate 135 and the ventilation hole 132. Optionally, a water absorption device 186 can be provided between the baffle 134 and the perforated plate 135 to absorb moisture in the air and prevent moisture from entering the container 100. In other words, a water absorption device 186 can be provided in the channel structure, which does not affect the circulation of gas while ensuring better water tightness of the box. For example, a water-absorbing sponge and / or water-absorbing resin can be provided between the baffle 134 and the perforated plate 135 to achieve the effects of filtering, absorbing water, and preventing moisture.

[0108] It should be noted that the water-absorbing sponge or water-absorbing resin should be fitted to the orifice plate 135 during installation, and should be arranged to cover the outside of the orifice plate 135 , so as to ensure the waterproof performance of the box.

[0109] Referring to Figures 12, 16, 17, and 19, a container 100 is provided with a discharge port 102 at one end in the longitudinal direction D1. A lintel beam 142, a threshold beam 143, and a discharge door 141 are provided at the discharge port 102. The lintel beam 142 is located in the middle of the height direction D3 of the container 100 and extends along the width direction D2 of the container 100. The threshold beam 143 extends along the width direction D2 of the container 100 and is spaced apart from the lintel beam 142 along the height direction D3. Specifically, the lintel beam 142 is connected between two corner posts 119 on either side of the discharge port 102. The threshold beam 143 is located at the bottom of the container 100 and connected between two bottom corner fittings of the container 100. In this embodiment, the discharge port 102 is located near the base frame 190 , and the lintel beam 142 , the threshold beam 143 and the corner column 119 together constitute the door frame of the discharge door 141 .

[0110] Specifically, the discharge door 141 is configured as an upward-turning door and is pivotally connected to the lintel beam 142 between an open position for opening the discharge port 102 and a closed position for closing the discharge port 102. Referring to FIG16 , the discharge door 141 is also provided with a handle 116 for easy operation by the operator.

[0111] Referring to Figure 16 , the discharge door 141 is provided with a locking rod 152. A first lock seat 151, which cooperates with the locking rod 152, is disposed near the threshold, that is, near the threshold beam 143, and is located on the corner posts 119 on both sides of the discharge port 102. When the discharge door 141 pivots to the closed position, the locking rod 152 and the first lock seat 151 cooperate to lock the discharge door 141 in the closed position.

[0112] In this embodiment, when the discharge door 141 is in the closed position, it can also seal the discharge port 102. Specifically, a first sealing strip 171 is provided on the circumferential edge 145 of the discharge door 141. When the discharge door 141 is pivoted to the closed position, the first sealing strip 171 can abut against the lintel beam 142, the threshold beam 143, and the corner post 119 to seal the gap between the discharge door 141 and the door frame, thereby improving the waterproof effect of the container 100 and preventing leakage of cargo inside the container.

[0113] As shown in Figure 19, the lintel beam 142 is further provided with an edge seal 142a near the inside 103 of the container 100. The edge seal 142a is configured to extend toward the door sill 143. When the discharge door 141 is pivoted to the closed position, the edge seal 142a and the inner surface 146 of the discharge door 141 face each other. The edge seal 142a blocks the gap between the discharge door 141 and the lintel beam 142 from the inside of the container 100, preventing material accumulation in the gap between the discharge door 141 and the lintel beam 142. This prevents bulk cargo from being trapped in the gap of the discharge door 141, making it difficult to open the door and damaging the first sealing strip 171.

[0114] Similarly, as shown in Figure 19, in this embodiment, the threshold beam 143 is partially bent to form a shielding surface 143a. The shielding surface 143a extends along the height direction D3 toward the lintel beam 142. When the discharge door 141 is pivoted to the closed position, the shielding surface 143a and the inner surface 146 of the discharge door 141 face each other. A second sealing strip 172 is provided between the discharge door 141 and the shielding surface 143a of the threshold beam 143. The second sealing strip 172 is attached to the inner surface 146 of the discharge door 141 and is configured to abut against the shielding surface 143a.

[0115] Optionally, the container 100 further includes a positioning assembly 160 , which can limit the closed position of the discharge door 141 and reduce the risk of damage to the locking rod 152 due to interference; the positioning assembly 160 can also achieve secondary locking of the discharge door 141 .

[0116] Specifically, referring to the embodiment shown in FIG17 , the positioning assembly 160 includes a positioning pin 161, a positioning block 162, and a second lock seat 163. The positioning block 162 is provided to the discharge door 141, and the second lock seat 163 is provided to the threshold beam 143. The positioning block 162 is provided with a first through hole 193, and the second lock seat 163 is provided with a second through hole 194. When the discharge door 141 pivots to the closed position, the positioning block 162 abuts against the outer surface 144 of the threshold beam 143, and the first through hole 193 and the second through hole 194 are coaxial. At this time, the positioning pin 161 can be inserted through the first through hole 193 and the second through hole 194 to lock the discharge door 141 in the closed position. Referring to FIG17 , in order to prevent the positioning pin 161 from being lost, in this embodiment, the positioning pin 161 is tied to the positioning block 162 by a hanging chain.

[0117] It should be noted that when positioning block 162 abuts outer surface 144 of door sill 143, discharge door 141 pivots to a position where the sealing strips (first sealing strip 171 and second sealing strip 172) precisely seal the gap between discharge door 141 and the door frame, ensuring a good seal while preventing excessive compression of the sealing strips. Thus, the provision of positioning assembly 160 can also extend the service life of the sealing strips.

[0118] According to an example of the present disclosure, the feed port 101 can also be configured to cooperate with an automated material transfer system, thereby realizing automation of cargo loading, reducing dust, improving loading efficiency, and reducing labor intensity.
