Description

Technical Field

[0001] This utility model relates to the technical field of containers, and more specifically to a combined container. Background Technology

[0002] Currently, the modular containers on the market, especially those with two or more layers, have only outer panels and corner posts supporting the outer side boxes at the joints between the upper and lower containers.

When the upper and lower containers are stacked, the elastic deformation at the joints exceeds the usage requirements, which obviously does not meet the requirements for multi-layer stacking. At the same time, due to the small assembly redundancy between the upper and lower containers during stacking, the stacking assembly is difficult and the operation is inconvenient.

[0003] Therefore, this utility model provides a combined container to at least partially solve the above-mentioned problems. Utility Model Content

However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0073] The preferred embodiments of this utility model will now be described with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0074] In this document, ordinal numbers such as “first” and “second” used in this invention are merely identifiers and do not have any other meaning, such as a specific order.

[0075] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0076] This utility model provides a combined shipping container. The combined container includes at least one first container, at least one second container, and a seam assembly. The first container includes a first container top beam, which includes a first flat portion and a first mating portion, the first mating portion protruding upwards relative to the first flat portion along the height direction. The second container is stacked on top of the first container, and the second container includes a second container bottom beam, which includes a second flat portion and a second mating portion, the second mating portion being recessed downwards relative to the second flat portion along the height direction. The seam assembly covers the gap between the first container top beam and the second container bottom beam along the height direction. The second flat portion is located above the first flat portion, and the second mating portion and the first mating portion are in a concave-convex fit along the height direction.

[0077] The combined container of this utility model has high strength in the stacking part. The stacking parts of the first container and the second container are concave and convex along the height direction, which makes stacking and assembly convenient and easy, while also being waterproof.

[0078] It should be noted that the "first direction" described in this utility model can be parallel to the length direction or the width direction of the combined container. The first direction is perpendicular to the height direction. When both the upper beam of the first container and the lower beam of the second container are end beams, the "first direction" is parallel to the length direction of the combined container. When both the upper beam of the first container and the lower beam of the second container are side beams, the "first direction" is parallel to the width direction of the combined container. The second direction is perpendicular to both the height direction and the first direction. "Inner" refers to the direction closer to the center of the assembled container, and "outer" refers to the direction farther from the center of the assembled container. The first and second containers can have multiple layers, and this is not intended to limit the combined container to only two layers, but only to limit the lower and upper containers of at least two adjacent layers of containers along the height direction in the combined container.

[0079] The following description uses an implementation method where both the upper beam of the first container and the lower beam of the second container are end beams (i.e., the upper beam of the first container and the lower beam of the second container are the upper end beam of the first container and the lower end beam of the second container, respectively).

[0080] The combined container 100 may include a first container 110 and a second container 130, with the second container 130 stacked on top of the first container 110. The corner fittings of the second container 130 and the corner fittings of the first container 110 are horizontally aligned. The bottom corner fittings of the second container 130 are adjacent to the top corner fittings of the first container 110 in the height direction DH and are horizontally aligned with each other.

[0081] The combined container 100 may also include at least two first containers 110 and at least two second containers 130. The at least two first containers 110 are arranged horizontally, and the at least two second containers 130 are arranged horizontally, with the second containers 130 stacked on top of the first containers 110. Similarly, the corner pieces of the second containers 130 correspond horizontally to the corner pieces of the first containers 110. For example, the second bottom corner piece 137 of the second container 130 is adjacent in the height direction DH to the first top corner piece 118 of the first container 110 and corresponds horizontally.

[0082] refer to Figures 1 to 5In the illustrated embodiment, the combined container 100 may include three first containers 110 and three second containers 130. The three first containers 110 are arranged sequentially along the second direction D2, and the three second containers 130 are arranged sequentially along the second direction D2. The three second containers 130 are stacked on top of the three first containers 110.

[0083] The combined container 100 includes at least one first container 110, at least one second container 130, multiple seals, and a seam assembly 150. The seam assembly 150 covers the gap between the first container 110 and the second container 130 along the height direction DH, specifically covering the gap between the upper beam 111 of the first container and the lower beam 131 of the second container. This improves the sealing performance of the combined container 100.

[0084] The first container 110 may include a first container top beam 111, a first container bottom frame 121, a refrigeration unit 160, a container door 122, first container bottom corner fittings, first container top corner fittings, first container side walls 123, and first container inner panels 124. The two first container top beams 111 are arranged opposite each other along the first direction D1.

[0085] refer to Figure 1 and Figure 3 The first container top beam 111 may include a first flat portion 112, a first mating portion 113, a mounting portion 117, a first vertical portion 116, a first reinforcing member 114, and a second reinforcing member 115. The first flat portion 112 is further outward than the first mating portion 113 along a first direction D1, and the first mating portion 113 protrudes upward relative to the first flat portion 112 along a height direction DH. The first vertical portion 116 extends downward from the outer end of the first flat portion, and the mounting portion 117 extends inward and downward from the lower end of the first vertical portion 116 for convenient installation of the refrigeration unit 160.

[0086] The first mating part 113 may include a first vertical plate 113a, a first horizontal plate 113b, and a second vertical plate 113c. The first vertical plate 113a extends upward from the inner end of the first flat plate. The first horizontal plate 113b is connected along the height direction DH to the upper end of the first vertical plate 113a and the upper end of the second vertical plate 113c. The second vertical plate 113c is further inward than the first vertical plate 113a. The lower end of the second vertical plate 113c is sealed and connected to the first sealing connector 172.

[0087] Mounting section 117 includes a first plate, a second plate, and a third plate. The first plate extends inward from the lower end of the first vertical section 116 along a first direction D1. The second plate extends downward from the inner end of the first plate along the first direction D1. The third plate extends inward from the lower end of the second plate along the first direction D1, and is connected to the first container inner panel 124 via snap-fit ​​member 126. The first container inner panel 124 can be sealed to the second vertical plate 113c of the joint assembly 150 and the first mating section 113 via a first sealing connector 172.

[0088] refer to Figure 1 and Figure 3 The snap-fit ​​part can have two snap-fit ​​grooves arranged opposite to each other along the first direction D1, so as to simultaneously snap-fit ​​the mounting part 117 of the first container upper beam 111 and the first container inner panel 124.

[0089] The refrigeration unit 160 includes a refrigeration unit frame 161 and a refrigeration unit body 162. The refrigeration unit frame 161 protrudes upwards from the refrigeration unit body 162 in the height direction DH. The refrigeration unit frame 161 can be fastened to the outside of the mounting part 117 via fasteners 184. Specifically, it can be fastened to the second plate of the mounting part 117. This allows the refrigeration unit 160 to be easily installed or disassembled, and ensures that the fasteners 184 do not protrude outwards from the first container top beam 111, which is both aesthetically pleasing and safe.

[0090] The second container 130 is stacked above the first container 110. The second container 130 includes a second container lower beam 131, a second container end wall 142, a second container side wall 141, a second container top plate 139, and a light 183. The second container lower beam 131 may include a second flat portion 132, a second mating portion 133, a third reinforcing member 134, a second vertical portion 135, a third reinforcing member 134, a fourth reinforcing member 136, and a fifth reinforcing member 144. The two second container lower beams 131 are arranged opposite each other along a first direction D1. The light 183 is located below the second container top plate 139.

[0091] The second mating portion 133 is recessed downward relative to the second planar portion 132 along the height direction DH. The second planar portion 132 is further outward than the second mating portion 133 along the first direction D1.

[0092] In some embodiments, the third reinforcing member 134 may be connected to the inner side of the second vertical portion 135. In other embodiments, the third reinforcing member 134 may be connected to the upper side of the second flat portion 132. In still other embodiments, the third reinforcing member 134 may be constructed as a rectangle, and the third reinforcing member 134 may be connected to both the inner side of the second vertical portion 135 and the upper side of the second flat portion 132. This further improves the strength of the second container lower beam 131, thereby improving the strength of the stacking portion of the combined container 100.

[0093] refer to Figure 3 In some embodiments, the fourth reinforcing member 136 may be disposed on the second transverse plate 133a of the second mating part 133. The fourth reinforcing member 136 may result in an inverted U-shaped configuration. The fifth reinforcing member 144 may connect the third reinforcing member 134 and the fourth reinforcing member 136 along the first direction D1, thereby connecting the third reinforcing member 134, the fourth reinforcing member 136, and the fifth reinforcing member 144 into a whole to improve the strength of the second mating part 133 and further improve the strength of the second container lower beam 131.

[0094] The second flat portion 132 is located above the first flat portion 112, and the second mating portion 133 and the first mating portion 113 are interlocked along the height direction DH. Thus, the container is connected to the container body via the seam assembly 150, resulting in high strength at the stacked portion. The interlocking of the first container 110 and the second container 130 along the height direction DH facilitates easy and simple stacking and assembly, and also improves sealing.

[0095] The dimension of the first planar portion 112 along the first direction D1 can be larger than the dimension of the second planar portion 132 along the first direction D1. The first container upper beam 111 also includes a first reinforcing member 114. The first reinforcing member 114 is disposed between the first container upper beam 111 and the second container lower beam 131 along the height direction DH. The first reinforcing member 114 is disposed between the second planar portion 132 and the first mating portion 113 along the height direction DH.

[0096] Optionally, the dimension of the first mating part 113 along the first direction D1 is smaller than the dimension of the second mating part 133 along the first direction D1. Therefore, when the second container 130 is stacked and assembled on top of the first container 110, the second container 130 can be directly fitted onto the first container 110 without adjusting its size, thus reducing the assembly difficulty.

[0097] The first reinforcing member 114 can be constructed as a rectangle. The first reinforcing member 114 is welded to the first flat portion 112, thereby forming a stepped structure between the first reinforcing member 114 and the first flat portion 112 to prevent water (e.g., rainwater, etc.) from entering the container from the outside of the combined container 100. Furthermore, the first reinforcing member 114 can further improve the strength of the first container upper beam 111, thereby improving the strength of the stacking part of the combined container 100.

[0098] In some embodiments, the second reinforcing member 115 may also be connected to the inner side of the first vertical portion 116. In other embodiments, the second reinforcing member 115 may also be connected to the lower side of the first flat portion 112. In still other embodiments, the second reinforcing member 115 is connected to both the inner side of the first vertical portion 116 and the lower side of the first flat portion 112. Thus, the strength of the first container upper beam 111 can be further improved by the second reinforcing member 115, thereby improving the strength of the stacking portion of the combined container 100.

[0099] The second reinforcing member 115 can be constructed as a rectangle or an L-shape, and the specific choice can be made flexibly according to actual needs.

[0100] The first container upper beam 111 may also include a seventh reinforcing member. Figure 3 (Not shown in the image) The seventh reinforcing member can connect the first flat portion 112 and the second reinforcing member 115, thereby further enhancing the connection strength and stability.

[0101] refer to Figure 3 The first container top beam 111 may also include an eighth reinforcing member 127, which is fixedly connected to the lower part of the first cross plate 113b, thereby further improving the strength of the first container top beam 111. The eighth reinforcing member 127 may be L-shaped. The eighth reinforcing member 127 extends downward from the first cross plate 113b to be sealingly connected to the first sealing connector 172.

[0102] refer to Figures 1 to 3 The combined container 100 may further include a first seal 171, which is disposed along the height direction DH between the first flat portion 112 and the second flat portion 132. The first seal 171 is constructed as an insulating elastic sheet. This further improves the sealing and insulation performance. The insulating elastic sheet can be a flat rubber strip.

[0103] The combined container 100 may further include a fourth seal 178, which is disposed along the height direction DH between the first reinforcing member 114 and the second mating part 133. This further improves the sealing performance of the combined container 100. The first seal 171 may be constructed as an insulating elastic sheet. This further improves both sealing and insulation performance. The insulating elastic sheet may be a flat rubber strip.

[0104] In some embodiments, the first seal 171 may be fixed to the first flat portion 112 of the first container's upper beam 111. Thus, when the second container 130 is stacked and assembled on top of the first container 110, the second container 130 compresses the first seal 171 under its own weight, thereby creating a sealing and insulation effect between the second flat portion 132 of the second container 130 and the first flat portion 112 of the first container 110.

[0105] In some embodiments, the fourth seal 178 may be fixed to the top of the first reinforcement 114 of the first container's upper beam 111. Thus, when the second container 130 is stacked on top of the first container 110, the second container 130 compresses the fourth seal 178 under its own weight, thereby creating a sealing and insulation effect between the second flat portion 132 of the second container 130 and the first reinforcement 114 of the first container 110.

[0106] The second mating part 133 of the second container lower beam 131 includes a second horizontal plate 133a, an inclined plate 133b, and a third vertical plate 133c. The inclined plate 133b extends upward along the height direction DH from the inner end of the second planar part 132 along the first direction D1 and inward along the first direction D1 to the second horizontal plate 133a. The second horizontal plate 133a extends inward along the first direction D1 from the top of the inclined plate 133b to the third vertical plate 133c. The waterproof structure of the inclined plate 133b of the second mating part 133 ensures that water will not seep into the connection and cause contamination.

[0107] The third vertical plate 133c extends upward from the inner end of the second horizontal plate 133a along the first direction D1 to connect to the second container inner panel 143 via the second sealing connector 173 (see below). This further improves the sealing and insulation performance. The second sealing connector 173 can be made of an insulating elastic material, such as PVC.

[0108] The inner panel 143 of the second container can be securely connected to the wall of the second container 130.

[0109] The seam assembly 150 may include a connecting housing 151 and a connecting plate 152. The connecting plate 152 extends upward and downward beyond the connecting housing 151 to connect the walls of the second container 130 and the first container 110, respectively. This facilitates sealing of the gap between the second container 130 and the first container 110 via the seam assembly 150. Specifically, the upper end of the connecting plate 152 is connected to a second sealing connector 173. The lower end of the connecting plate 152 can be connected to a first sealing connector 172. This further improves both insulation and sealing performance.

[0110] refer to Figure 3The first sealing connector 172 and the second sealing connector 173 both have snap-fit ​​grooves to snap-fit ​​the first container inner panel 124 and the second container inner panel 143 respectively.

[0111] An insulation section 154 may be provided inside the connecting shell 151. This further improves the insulation performance of the stacked parts of the combined container 100, thereby improving the overall insulation performance of the combined container 100. The insulation section 154 may be in the form of a block or plate, such as polyurethane foam material.

[0112] The combined container 100 may also include a first sealing connector 172 and a second sealing connector 173. The first sealing connector 172 is sealed to the inner lower end of the first container upper beam 111 and the container wall of the first container 110 or the outer lower end of the first container upper beam 111 via the first container inner panel 124.

[0113] The second sealing connector 173 is sealed to the wall of the second container 130 and the inner upper end of the lower beam 131 of the second container. The joint assembly 150 also includes two second seals 153. One second seal 153 extends upward from the upper end of the connecting housing 151 and is connected to the first sealing connector 172. The other second seal 153 extends downward from the lower end of the connecting housing 151 and is connected to the second sealing connector 173.

[0114] The second container lower beam 131 may also include a sixth reinforcing member 145, which is fixedly connected to the fourth reinforcing member 136. The fourth reinforcing member 136 is connected to the upper side of the second mating part 133 and can be sealed to the second sealing connector 173 via the sixth reinforcing member 145. This further improves the strength and ensures the sealing performance.

[0115] refer to Figure 3 The combined container 100 may also include a third seal 174, which is disposed in the gap between the upper beam 111 of the first container and the lower beam 131 of the second container. This further improves the sealing and insulation performance.

[0116] refer to Figure 5 Three second containers 130 are stacked on top of three first containers 110. The outermost first top corner piece 118 and its corresponding second bottom corner piece 137 along the first direction D1 can be connected via a first twist-lock connector 175. This ensures the connection stability between the first containers 110 and the second containers 130, guaranteeing safety after stacking.

[0117] Two adjacent bottom corner pieces 119 of two adjacent first containers 110 along the first direction D1 can be connected via a second twist-lock connector 176. This ensures the stability and security of the connection between the two or more first containers 110. Two adjacent top corner pieces 138 of two adjacent second containers 130 along the first direction D1 can be connected via a second twist-lock connector 176. This ensures the stability of the connection between the two or more second containers 130 and guarantees the safety after stacking and assembly.

[0118] The two adjacent first corner brackets 118 of two adjacent first containers 110 and the two adjacent second corner brackets 137 of their corresponding adjacent second containers 130 are connected via a third twist-lock connector 177. This further ensures the connection stability between the two adjacent first containers 110 and the two adjacent second containers 130 above them, guaranteeing the safety after stacking and assembly.

[0119] refer to Figure 2 and Figure 4 The first container 110 may further include two upper side beams 128, which are arranged opposite each other along the second direction D2. The second container 130 may further include two lower side beams 146, which are arranged opposite each other along the second direction D2. The connection between the upper side beams 128 and the lower side beams 146 along the height direction DH is similar to... Figure 1 and Figure 3 The connection between the first container upper beam 111 and the second container lower beam 131 is provided, and the two are connected by a seam assembly 150. Figure 1 and Figure 3 The connection between the first container upper beam 111 and the second container lower beam 131 is different in that, since the first container side wall 123 is not equipped with a refrigeration unit 160, the lower end of the first container upper side beam 128 is directly connected (e.g., welded) to the wall panel of the first container 110. Figure 2 and Figure 4 The connection between the upper side beam 128 of the first container and the lower side beam 146 of the second container shown is illustrated below. The remaining undescribed parts are referred to... Figure 1 and Figure 3 The description and accompanying drawings of the connection between the first container upper beam 111 and the second container lower beam 131 are omitted for brevity.

[0120] Of course, the refrigeration unit 160 may not be installed at the front end of the first container 110. In an embodiment without the refrigeration unit 160, it can be similar to the embodiment shown in the figure. Figure 4As shown, the first container upper beam 111 does not have an installation part 117, and the first vertical part 116 extends directly downward and is connected (e.g., welded) to the wall panel of the first container 110.
