Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, in particular to a container. Background Art

[0002] A container made by foaming panels, where all panels are assembled after foaming. Figure 1 As shown, the top plate 10 includes an outer top plate 11, an inner top plate 12 and a top plate foaming layer 13, and the side plate 20 includes an outer side plate 21, an inner side plate 22 and a side plate foaming layer 23. After assembly, the top plate 10 and the side plate 20 are in contact with each other at the overlapping corners to form a cavity area 60. In order to prevent thermal bridges or the cavity area 60 from causing a decrease in the insulation effect of the box and an increase in the heat leakage value, the cavity area 60 needs to be filled with foam through secondary foaming. In order to prevent water vapor from entering the foam and increase the overall strength of the box, the joints between the side plate 20 and the top plate 10 of the container need to be riveted and sealed with a top corner seal 41.

[0003] In the container of the prior art, the problems existing in the connection structure of the top plate 10 and the side plate 20 include at least the following: First, the secondary foaming greatly restricts the production efficiency of the container. Secondly, the foaming pressure during the secondary foaming is very large. In order to prevent the box sheet from being deformed and to ensure the density of the secondary foamed body, it is necessary to use a mold to maintain the pressure. The use of mold tooling is large and the equipment investment is large. Finally, for the foaming of the cavity area 60, it is necessary to open the injection hole 31 in the top side beam 30, and then seal the injection hole 31 with a rivet 50, which increases the workload and the use of the rivet 50, which is not conducive to cost saving. In addition, because the length direction of the box is long, in order to fix the top corner seal 41 to achieve the sealing effect, the number of rivets 50 used is very large, resulting in a great waste of man-hours and costs, and also increases the risk of water vapor entering the foam body, which is not conducive to product quality assurance and cost saving.

[0004] Therefore, a container is needed to at least partially solve the above problems. Utility Model Content

[0005] A series of simplified concepts are introduced in the utility model content section, which will be further described in detail in the detailed implementation section.

The top plate 110 comprises an inner top plate 112, an outer top plate 111 fixedly connected to the top side beam top 130a, and a top plate foaming layer 113 disposed between the inner top plate 112 and the outer top plate 111. The side plate 120 comprises an inner side plate 122, an outer side plate 121 fixedly connected to the top side beam side portion 130b, and a side plate foaming layer 123 disposed between the inner side plate 122 and the outer side plate 121. The top plate foaming layer 113 extends to the top side beam side portion 130b of the top side beam 130, thereby preventing the corner where the top plate 110 and the side plate 120 are connected from forming a cavity.

[0062] In a preferred embodiment, the top plate foam layer 113 extends and is connected to the side portion 130b of the top side beam, and the top plate foam layer 113 is in contact with the side plate foam layer 123, so that the top plate foam layer 113 and the side plate foam layer 123 fill the connection area between the top plate 110, the side plate 120 and the top side beam 130, avoiding the formation of a cavity and avoiding secondary foaming.

[0063] Specifically, when the top plate foam layer 113 extends to the top side beam side portion 130 b of the top side beam 130 , the lower side surface of the top plate foam layer 113 contacts the upper end surface of the side plate foam layer 123 .

[0064] In this embodiment, the top plate foam layer 113 extends to the top side beam side portion 130 b , so the inner top plate 112 at least partially overlaps with the top end surface of the side plate foam layer 123 to facilitate the manufacture of the top plate foam layer 113 .

[0065] In some preferred embodiments, the inner side plate 122 includes an inner side plate body 122a and a side plate connecting portion 122b. The side plate connecting portion 122b is bent and connected to the inner side plate body 122a, so that the side plate connecting portion 122b can be fixedly connected to the inner top plate 112 in a fitting manner.

[0066] Optionally, the side panel connecting portion 122b is connected to the inner top panel 112 by fasteners (such as rivets 50). Therefore, the connection between the top panel 110 and the side panel 120 does not need to use the top corner seal 41, the number of fasteners and seals required is reduced, and the sealing effect is better.

[0067] Preferably, a sealant is provided at the connection between the inner side plate 122 and the inner top plate 112 to enhance the sealing effect of the connection and prevent moisture from entering the foam of the foam layer. That is, a sealant, such as a sealant 42 and a sponge tape 43, is provided at the connection between the side plate connection portion 122b and the inner top plate 112.

[0068] The second preferred embodiment of the utility model is a variation of the first preferred embodiment. The container of the second preferred embodiment has a similar structure and / or configuration as the container of the first preferred embodiment. Therefore, elements having substantially the same functions as those in the first preferred embodiment will be numbered the same here, and will not be described and / or illustrated in detail for the sake of brevity.

[0069] exist Figure 3 The container according to the second embodiment of the present utility model shown in the figure comprises a top plate 210, a side plate 220 and a top side beam 130. The top plate 210 comprises an outer top plate 211, an inner top plate 212 and a top plate foaming layer 213, wherein the top plate foaming layer 213 is located between the outer top plate 211 and the inner top plate 212.

The outer top plate 211 is fixedly connected to the top side beam top 130a of the top side beam 130, and the outer side plate 221 is fixedly connected to the top side beam side 130b of the top side beam 130. The inner side plate 222 is sealed to the inner top plate 212 , and the side plate foaming layer 223 extends to the top side beam top 130 a of the top side beam 130 , thereby preventing the corner where the top plate 210 and the side plate 220 are connected from forming a cavity.

[0070] In a preferred embodiment, the side panel foaming layer 223 extends to the top of the top side beam 130a, is connected to the top of the top side beam 130a and the outer top plate 211, and is in contact with the top plate foaming layer 213, so that the top plate foaming layer 213 and the side panel foaming layer 223 fill the connection area between the top plate 210, the side plate 220 and the top side beam 130, avoiding the formation of a cavity and avoiding secondary foaming.

[0071] Specifically, when the side plate foam layer 223 extends to the top side beam top portion 130 a of the top side beam 130 , the inner side surface of the side plate foam layer 223 contacts the end surface of the top plate foam layer 213 .

[0072] In this embodiment, the side panel foam layer 223 extends to the top 130 a of the top side beam, and the inner side panel 222 at least partially overlaps with the end surface of the top panel foam layer 213 to facilitate the manufacture of the side panel foam layer 223 .

[0073] In some preferred embodiments, the inner top plate includes an inner top plate body 212a and a top plate connecting portion 212b, and the top plate connecting portion 212b is bent and connected to the inner top plate body 212a so that the top plate connecting portion 212b can be fixedly connected to the inner side plate 222 in a fitting manner.

[0074] Optionally, the top plate connecting portion 212b is connected to the inner side plate 222 by fasteners (such as rivets 50). Therefore, the connection between the top plate 210 and the side plate 220 does not need to use the top corner seal 41, the number of fasteners and seals required is reduced, and the sealing effect is better.

[0075] Further preferably, a sealant is provided at the connection between the inner side plate 222 and the inner top plate 212 to enhance the sealing effect of the connection and prevent moisture from entering the foam of the foaming layer. That is, a sealant, such as a sealant 42 and a sponge tape 43, is provided at the connection between the top plate connection portion 212b and the inner side plate 222.

[0076] In one embodiment, the top beam side portion 130b of the top beam 130 includes a vertical extension portion 130b1 and an inclined extension portion 130b2, and the inclined extension portion 130b2 is located between the vertical extension portion 130b1 and the top beam top portion 130a. The side end portion of the top plate foam layer 113 extending to the top beam side portion 130b is adapted to the shape of the top beam 130 to fill the space formed by the top plate 110, the side plate 120 and the top beam 130. The upper end portion of the side plate foam layer 223 extending to the top beam top portion 130a is adapted to the shape of the top beam 130 to fill the space formed by the top plate 210, the side plate 220 and the top beam 130.

[0077] Optionally, the side panel foaming layers 123 , 223 and the top panel foaming layers 113 , 213 are made of polyurethane rigid foam.

[0078] According to the container of the utility model, the foaming size of the top plate 110 or the side plate 220 is increased so that after the top plate 110 and the side plate 120 (top plate 210 and side plate 220) are assembled, the corner formed by the two has as few cavity areas as possible. Therefore, the structure at the connection between the top plate 110 and the side plate 120 (top plate 210 and side plate 220) can be exempted from secondary foaming, and thus there is no need to open a material injection hole in the top side beam 130 and seal it with rivets, which can speed up the production rhythm of the container, reduce the use of pressure-maintaining tooling, and save costs. In addition, the inner top plate 212 is set as a bending structure directly connected to the inner side plate 222, or the inner side plate 122 is set as a bending structure directly connected to the inner top plate 112, which can eliminate the use of the top corner seal 41, reduce the number of required fasteners and seals, and achieve better sealing effect.
