Description

Technical Field

[0001] The present invention relates to logistics equipment, in particular to a foldable container, especially an intermediate bulk container. Background Art

[0002] Foldable intermediate bulk container, also known as foldable IBC, is mainly composed of a base, two pairs of side panels and a lid. Due to its foldable nature, it has obvious cost advantages in empty container storage and return transport compared to traditional non-foldable IBC, so it is widely favored by users in the field of liquid packaging. The traditional foldable IBC structure is roughly as follows: Fig.15 As shown, two pairs of side panels are connected to the base, and adjacent side panels are connected by a bite structure roughly at the corner of the container. Generally, the pair of side panels with shorter width are folded first, and then the other pair of side panels are folded. The advantage of such a structure is that the short side panels are located between the two long side panels when upright, which can help the long side panels resist external push / pressure, but the width of the long side panels is almost the same as that of the base, and the long side panels must lie on the short side guards of the base when folded. In this way, the short side guards and long side guards of the base are not at the same height, making the rigidity of the long side guards to resist the lateral pressure of the liquid when the container is fully loaded not ideal, and even need to add support members inside the base to make up for its lack of strength.

[0003] Stacking containers outdoors is a common usage scenario for IBCs. When the side panels are folded, the height of the base edge guards of traditional IBCs is inconsistent, so that after the cover is closed, there is still a part of the short side edge area that cannot be covered by the cover. After long-term storage, rainwater, dust, etc. will inevitably accumulate in the box, causing mildew or insects, which brings great hygiene problems and increases the difficulty of cleaning.

[0004] Therefore, there is a need in the art for a container that can remain sanitary after being stored outdoors for a long time. Summary of the invention

[0005] The purpose of the present invention is to provide a container to solve the problem of contamination inside the container caused by long-term outdoor storage in the prior art.

[0014] In one embodiment, the connecting body is provided with a hinge hole, and one of the reinforcement members in the reinforcement assembly can be rotatably inserted into the corresponding hinge hole of the connecting body.

[0015] In one embodiment, the side panel comprises an inner panel, an outer panel, and the reinforcing assembly is located between the inner panel and the outer panel, wherein the inner panel and the outer panel are connected to each other.

[0016] In one embodiment, a first biting structure is provided on the second side edge of the connecting body on which one of the side panels is arranged, which is opposite to its first side edge; a second biting structure is provided on the second side edge of the connecting body on which the side panel adjacent to the side panel is arranged, which is opposite to its first side edge, wherein the first biting structure and the second biting structure are operably engaged with each other.

[0017] In one embodiment, the second side edge of the connector provided on one of the side panels and the second side edge of the connector provided on another side panel adjacent to the side panel are provided with mutually matching locking structures.

[0018] In one embodiment, the base comprises a bottom plate and two pairs of opposite protruding plates extending from the periphery of the bottom plate, wherein the heights of the two pairs of opposite protruding plates are the same.

[0019] In one embodiment, the distance between the inner sides of any pair of opposite protruding plates of the base is greater than or equal to the total width of the corresponding side plates.

[0020] In one embodiment, the height of the protruding plate of the base is greater than the sum of the thicknesses of two pairs of opposite side plates.

[0047] Foldable composite IBC (Intermediate Bulk Container) is widely used in the field of logistics. Its dimensions are usually about 1.2 meters long and 1 meter wide. It generally has a base, two pairs of side panels, and a cover, wherein the side panels and the base are detachably connected together.

[0048] See also Figure 1 The container 100 according to the present invention comprises: a base 1, two pairs of opposite side panels 2 and 3 extending vertically from the base 1 and connected to each other, and a cover plate 4 arranged opposite to the base 1. The two pairs of opposite side panels 2 and 3 are detachably connected to the base 1 at the bottom edge, and the two pairs of opposite side panels 2 and 3 are provided with connectors at the edges of both sides, and two adjacent side panels 2 and 3 are operably connected to each other through the cooperation between the corresponding connectors. The two connectors that cooperate with each other constitute corner components 5 and 6. Each side panel 2 and 3 can be hingedly connected to the base 1, so that when not in use, each side panel 2 and 3 can be folded relative to the base 1 for easy storage and storage.

[0049] Figure 2The stereogram of the base 1 is shown. The base 1 comprises a substantially rectangular bottom plate 19 and two pairs of opposite protruding plates 18 extending vertically from the periphery of the bottom plate 19, wherein the heights of the two pairs of opposite protruding plates are the same. A plurality of openings are provided on the inner side of each protruding plate, and the figure shows three openings 11, 12, 13 on one protruding plate 18 and three openings 14, 15 and 16 on another protruding plate. Each opening is open upward and inward, and is used to receive each protruding portion provided on the bottom edge of the side panels 2 and 3, respectively. Each opening is optionally provided with a hanging groove 131, 141 or a hinge groove 132, 142 to cooperate with the hanging platform 241, 331 or the hinge pin 242, 332 optionally provided on each protruding portion on the bottom edge of the side panels 2 and 3 to form a hinged structure of the side panel relative to the protruding plate 18, so that the side panel can be folded in the box. In order to facilitate the stacking of the side panels, the height of the slotted openings 14, 15 and 16 on a pair of extended panels in the illustrated embodiment is greater than the height of the openings 11, 12 and 13 on the other pair of extended panels 18. Thus, a pair of side panels can be folded at different heights relative to the other pair of side panels, thereby facilitating the stacking of the side panels.

[0050] A discharge port 9 is provided between the bottom plate 19 and the extension plate 18 of the base 1, and the discharge port 9 communicates the inside and the outside of the base 1, so as to facilitate the discharge of the contents of the container 100 to the outside when necessary. Figure 1 and 2 As shown, the base 1 is further provided with a forklift hole 10 below the bottom plate 19 , so that the fork of a forklift can be inserted therein to carry the container 100 .

[0051] Figure 3 The three-dimensional view of each side panel 2 and 3 connected to each other is shown. The bottom edge of the side panels 2 and 3 is provided with a protrusion extending downward from the bottom edge, and the figure shows the protrusions 24, 25 and 26 extending downward from the bottom edge of one side panel 2 and the protrusions 31, 32 and 33 extending downward from the bottom edge of one side panel 3. Each protrusion can be received in each open portion accordingly to achieve the connection between each side panel 2 and 3 and the base 1. Optionally, the corresponding protrusion is also provided with a hanging platform 241, 331 or a hinge pin 242, 332 to cooperate with the hanging groove 131, 141 or the hinge groove 132, 142 optionally provided in each open portion to form a hinge connection structure, so that each side panel can be folded in the container. Although the drawings show that each side panel is connected to the base 1 through three groups of open portions and protrusions, it should be understood that the number of open portions and protrusions can also be set as needed without departing from the scope of the present invention.

[0052] Figure 4The figure shows a stereoscopic view of one side of the side panel 2. As shown in the figure, the side panels 2 are provided with grooves 21, 22 and 23 arranged in sequence from bottom to top. The grooves 21, 22 and 23 penetrate the thickness of the side panel 2 and are spaced apart from each other along the side edges. The side panels 3 are also provided with the same grooves on the side edges, which will not be described in detail here.

[0053] The side panels 2 and 3 are formed by connecting two layers of panels spaced apart from each other. The side panel 2 is provided with a reinforcement assembly between the two layers of panels, i.e., the inner panel and the outer panel. The two sides of the reinforcement assembly respectively include two vertical pivot tubes 7 vertically penetrating the side panel 2. The pivot tubes 7 are exposed from the side panel 2 at each of the slots 21, 22 and 23. The other side panels 2 and 3 are also provided with slots and reinforcement assemblies. The reinforcement assembly can be made of a material with higher strength than the two layers of panels of the side panel 2. For example, the reinforcement assembly can be formed by connecting a plurality of transverse reinforcement members and a plurality of vertical reinforcement members to form a frame structure. However, it should be understood that the reinforcement assembly can be arranged in other ways as required.

[0054] Figure 5 and 6 The perspective view of the corner assembly 6 is shown. The height of the corner assembly 6 is the same as that of the side panels 2 and 3. The corner assembly 6 is composed of a connector 6a and a connector 6b. The outer sides of the connectors 6a and 6b are their first side edges, and the first sides of the connectors 6a and 6b are respectively provided with extensions 6a1, 6a2, 6a3 and 6b1, 6b2, 6b3. Each extension is provided with a vertically extending through hole 6a4 and 6b4 for interconnecting with a pivot tube. Each extension 6b1, 6b2, 6b3 corresponds to each slot 21, 22 and 23 on the side panel, respectively, and can be inserted into each slot 21, 22 and 23. The pivot tube 72 can be inserted into each extension 6b1, 6b2, 6b3 in sequence, thereby forming a hinged connection with the side panel 2. The vertically extending through hole 6b4 is used as a hinge hole, and the pivot tube 72 can be rotatably inserted into the vertically extending through hole 6b4. Thus, one side of the corner component 6 is hingedly connected to the side panel 2. The other side of the corner component 6 is also hingedly connected to the adjacent side panel 3. Thus, the two adjacent side panels 2 and 3 are connected to each other through the corner component 6. However, it should be understood that the side panels and the connector can be hingedly connected by other methods known in the art without departing from the scope of the present invention.

[0055] In the present invention, the side panels 2 and 3 are both provided with reinforcement components, and the side panels 2 and 3 are connected to each other through the corner components 5 and 6 connected to the pivot tube 7 of the reinforcement component, thereby replacing the direct bite between the side panels in the prior art to achieve a higher strength connection. Since the existing bite structure is eliminated for the side panels 2 and 3, the manufacturing process is no longer limited to welding processes such as hot plate welding or vibration friction welding, and twin sheet forming or blow molding processes can also be used.

[0056] like Figure 5 and 6 As shown, the side of the connectors 6a and 6b opposite to each other is a second side edge, and the second side edges of the connectors 6a and 6b are respectively provided with a first bite structure 6a5 and a second bite structure 6b5. The first bite structure 6a5 and the second bite structure 6b5 are operably engaged with each other. The connectors 6a and 6b are connected to each other through the first bite structure 6a5 and the second bite structure 6b5. The bite structure is an engagement tooth, an engagement groove or an engagement hook extending from the opposite edges of the connectors 6a and 6b along the extension plane where the connectors are located. The shape of the engagement structure can be dovetail-shaped, T-shaped or other shapes. The extension direction of the engagement structure is set so that the connector can be disengaged from the engagement with the adjacent engagement body after rotating around the axis hole ( Fig. 9 ). This structure allows the connectors 6a and 6b to rotate a certain angle around the pivot tube 7 of the side plate, so that the two connectors in the connected state can be disconnected, thereby allowing a folding operation. In the illustrated embodiment, the connectors 6a and 6b are located in the same plane with each other when they are engaged with each other.

[0057] Figure 7 The top view of the container 100 of the present invention in the use state is shown. Figure 8 Shows Figure 1 The enlarged image of the circled part. Figure 7 As shown, the adjacent side panels 2 and 3 are connected to each other by corner components 5 and 6. Wherein the corner components 5 and 6 are respectively formed by a pair of connectors and are arranged at an angle with the adjacent side panels. Thus, from a top view, the connector of each side panel is inclined toward the container relative to the side panel, and a pair of connectors of the corner components are located on the same plane, so two pairs of side panels 2 and 3 and two pairs of corner components 5 and 6 form an octagonal shape. In the preferred embodiment shown, the corner components 5 and 6 are at an angle of 45° with the plane where the side panels are located, but it should be understood that the corner components 5 and 6 can also be at other angles with the plane where the side panels are located. The sum of the width W0 of each side panel and the width W1 of the connector connected to the side panel projected on the normal direction of the side panel is less than the distance between the inner wall surfaces of a pair of adjacent side panels. When the connector connected to the side panel can be expanded relative to the side panel, the sum of the width W0 of each side panel and the width W2 of the connector connected to the side panel after expansion is also less than the distance between the inner wall surfaces of a pair of adjacent side panels.

[0058] like Figure 8As shown, when the side panel 2 and its connector are flattened, the distance between the first side edge of the connector and the plane where the inner wall surface of the adjacent side panel 3 is located is D1, and when the side panel 3 and its connector are flattened, the distance between the first side edge of the connector and the plane where the inner wall surface of the adjacent side panel 2 is located is D2. In order to ensure that the side panel does not interfere with the adjacent side panel during the folding process and can be folded into an adjacent pair of protruding panels 18, D1 and D2 should be greater than zero. Preferably, D1 ≥ 3mm, and D2 ≥ 3mm. Due to this size setting, the total width of each side panel and the connector connected to it after flattening is smaller than the width between a pair of protruding panels 18 of its adjacent base 1, so that each side panel can be completely laid flat in the container base after being folded relative to the base 1 ( Fig.12 ), therefore, the four protruding plates of the base 1 can be set to the same height.

[0059] Fig. 9 A schematic diagram showing a connector of a corner assembly 6 of a container 100 according to the present invention rotates relative to a side panel 2 to disengage from an adjacent connector. In the figure, a connector 6a connected to the side panel 2 rotates inwardly around a hinge hole and is at an angle α relative to the connector 6a in the use state.

[0060] Fig.10 2 shows a schematic diagram of the side panel 2 of the container 100 according to the present invention being folded downward relative to the base 1. As shown in the figure, during the folding process, the side panel 2 and the connecting bodies 6a and 5a connected thereto are in a flattened state, and during the folding process, the distance between the side panel 2 and its connecting bodies 6a and 5a and the inner walls of two adjacent side panels 3 is D2, thereby ensuring that the side panel 2 and its connecting bodies 6a and 5a are completely placed between the corresponding pair of protruding panels 18 of the base 1.

[0061] Fig.11 1 shows a top view of the container 100 according to the present invention, in which both pairs of side panels are folded on the base 1, wherein the side panel 3 is located above the side panel 2. As shown in the figure, during the folding process, the side panel 3 and the connecting bodies 6b and 5b connected thereto are in a flattened state, and during the folding process, the distance between the side panel 3 and its connecting bodies 6a and 5a and the inner walls of the two adjacent side panels 2 is D1, thereby ensuring that the side panel 3 and its connecting bodies 6a and 5a are completely placed between the corresponding other pair of protruding panels 18 of the base 1.

[0062] Fig.12 1 shows a three-dimensional view of a container 100 according to the present invention when both pairs of side panels 2 and 3 are folded on the base 1. As shown in the figure, the height of the extension panel 18 is greater than the sum of the thicknesses of the two pairs of side panels 2 and 3, so the two pairs of side panels 2 and 3 are placed flat in the space surrounded by the extension panel 18 and do not protrude from the extension panel 18. Therefore, after folding, the cover panel 4 can be placed on the folded box body. Back Figure 1The cover plate 4 has a cover plate body 41 and an outer peripheral edge extending downward from the cover plate body 41, and the inner peripheral surface profile of the outer peripheral edge matches the outer peripheral surface profile of the extension plate 18, so that the cover plate 4 can be tightly covered on the folded box body. This structure ensures that even if the container 100 of the present invention is placed outdoors in a folded storage state, it will not be polluted by rainwater or the like.

[0063] Fig.13 and 14 Another embodiment of the container according to the present invention is shown. The difference between this embodiment and the previous embodiment is that the two connectors of the corner assembly are respectively formed integrally with the side panels 2 and 3, and the adjacent connectors are located on the same plane. In the preferred embodiment shown, the corner components 5 and 6 are at an angle of 45° to the plane where the side panels are located, but it should be understood that the corner components 5 and 6 can also be at other angles to the plane where the side panels are located. The edges of the two connectors of the corner assembly facing each other are provided with a bite structure that cooperates along the direction parallel to the extension direction of the side panels 3. Fig.14 Shows Fig.13 The enlarged view of the circled part in the figure, wherein the edge of the side panel 2 is integrally provided with a connector 2a, and the edge of the side panel 3 is integrally provided with a connector 3a, the edge of the connector 2a is provided with a hook 2b, and the outer end 3b of the connector 3a is formed with a corresponding slot, and the hook 2b of the connector 2a is inserted into the slot of the connector 3a along the extension direction parallel to the side panel 3, so as to realize the bite between the connectors. When the side panels 2 and 3 need to be folded, the side panel 2 is folded first, and the bite between the side panel 2 and the side panel 3, that is, the bite between the connectors 2a and 3a is disengaged while the side panel 2 is folded downward. Then the side panel 3 is folded downward. The distance between the outer edge of the connector 2a and the plane where the inner wall surface of the side panel 3 is located is D4, and the distance between the outer edge of the connector 3a and the plane where the inner wall surface of the side panel 2 is located is D3. Similarly, D4 ≥ 3 cm, D3 ≥ 3 cm, so as to ensure that a certain gap is maintained between the side panels 2 and 3 and the adjacent side panels and the extended panels 18 during the folding process, and to ensure that the side panels and their connectors are completely placed flat between the corresponding pair of extended panels 18 of the base 1. Similarly, the sum of the width W0 of each side panel and the width W1 of the connector connected to the side panel projected in the normal direction of the side panel is less than the distance between the inner wall surfaces of the adjacent pair of side panels.

[0064] In addition, the engagement between adjacent side panels needs to be locked, which can be achieved by any locking mechanism known or to be developed in the prior art, which will not be described in detail herein. Preferably, the relative connectors provided with adjacent side edges of two adjacent side panels are provided with mutually cooperating locking mechanisms 6c.

[0065] The inventor found that by chamfering the traditional side panels at the connecting corners and then designing the interlocking structure according to certain size specifications, the side panels can be completely folded into the extended panels of the base. The chamfer can be a certain angle (30° to 45°), or a rounded angle or a near-rounded angle. When the side panels are completely folded into the base, the four extended panels of the base can be designed to be of uniform height, and it is convenient to keep the box in a better sanitary condition.

[0066] Preferred embodiments of the present invention have been described above in detail, but it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide further embodiments.

[0067] These and other changes can be made to the embodiments in light of the above detailed description.In general, in the claims, the terms used should not be considered limited to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which these claims are entitled.
