Description

Technical Field

[0001] This utility model relates to the technical field of logistics and transportation, and in particular to a container. Background Technology

[0002] Collapsible containers significantly reduce space usage when empty, offering greater cost advantages for warehousing and return logistics compared to non-collapsible containers. As a result, more and more industries are seeking to replace non-collapsible containers; for example, in the liquid packaging sector, collapsible containers are gradually replacing integrated tonne containers. A typical collapsible container consists of a base, two pairs of side panels, and a lid. One side panel also features a small door that opens outwards, allowing workers to easily enter the container for operations. When folded, the first side panel folds roughly flush with the base's support surface, and then the remaining side panels fold sequentially, creating a folded state where the length and width remain the same but the height is reduced. This smaller volume configuration results in various logistical and warehousing benefits.

[0003] Because smaller folded volume brings better savings, the structure of foldable containers is often designed so that the overlap gap between the folded side panels and the adjacent folded side panels or base is as small as possible. This will bring some other inconveniences. For example, some foldable containers that require the use of heating plates need to remove the heating plates after use before the container can be folded, or the safety performance of the heating plates must be sacrificed to minimize the thickness of the heating plates in order to fold with the heating plates.

[0087] This utility model relates to a container 100, which includes a base 1, a first set of side plates, a second set of side plates, a lid 6, a heating plate, and a partition. The base 1 includes a bottom plate 11 and two extension plates 12. The bottom plate 11 is rectangular and has a pair of oppositely arranged first side edges 13 and a pair of oppositely arranged second side edges 14. The first side edges 13 extend along a first direction, and the second side edges 14 extend along a second direction.

[0088] Two extension plates 12 are respectively connected to a pair of second side plates 14 and extend upward.

[0089] The first set of side panels includes a first side panel 2 and a second side panel 3 arranged opposite to each other, while the second set of side panels includes two third side panels 4 arranged opposite to each other.

[0090] The first side plate 2, the second side plate 3, and the pair of third side plates 4 are foldably connected to the four sides of the base 1. Specifically, the first side plate 2 and the second side plate 3 are short side plates and are arranged opposite each other, while the two third side plates 4 are long side plates and are arranged opposite each other. The first side plate 2 and the second side plate 3 are respectively hinged to a pair of first side edges 13 of the base plate 11, and the pair of opposite third side plates 4 are respectively hinged to the top surfaces of two extension plates 12. The two extension plates 12 are mainly used to facilitate the folding of the pair of third side plates 4 inward. The folding direction of the first side plate 2, the second side plate 3, and the third side plate 4 to the base 1 is not restricted.

[0091] In the folded state, the first set of side panels is stacked on the top surface of the base, and the second set of side panels is stacked on the top surface of the first set of side panels. The first side panel 2 of the first set of side panels can be located on the top surface of the base 1, and the second side panel 3 can be located on the top surface of the first side panel 2. Alternatively, the second side panel can be located on the top surface of the base, and the first side panel can be located on the top surface of the second side panel.

[0092] In the embodiment shown in the figure, the first side plate 2 is located on the top surface of the base 1, the second side plate 3 is located on the top surface of the first side plate 2, and a pair of third side plates 4 are stacked on the top surface of the second side plate 3 in sequence. That is, from bottom to top, they are the base plate 11, the first side plate 2, the second side plate 3 and a pair of third side plates 4.

[0093] The lid 6 fits onto the top surface of the four side panels and can be detachably assembled or connected to the four side panels.

[0094] The partition is located between the top surface of the base plate 11 of the base 1 and the first set of side plates. The partition creates a receiving space 16 between the first set of side plates and the base 1, which can be used to receive the heating plate.

[0095] The container 100 of this utility model is foldable. The partition is used to support the first side plate 2, the second side plate 3 and the third side plate 4. That is, a support structure is established between the multiple side plates and the bottom plate 11, so that the side plate that is folded first (that is, one of the first side plate and the second side plate) and the bottom plate 11 form a accommodating space 16 with a height of not less than a certain height. This allows the container 100 to have a certain amount of redundant space to store heating plates and other accessories that need to be included in the box, even when folded. This facilitates the management of the included accessories and can provide a certain degree of protection for the included accessories.

[0096] The base plate 11 is also provided with a discharge port 15 at a certain position. The discharge port 15 is preferably located at the edge of the base 1, for example, near the first side 13 or the second side 14.

[0097] Furthermore, to facilitate liquid discharge, the top surface height of the base plate 11 gradually decreases from the adjacent and opposite sides of the discharge port 15 to the discharge port 15. In other words, the top surface of the base plate 11 can be designed with a slope sloping towards the discharge port 15, with this slope gradually decreasing from the adjacent and opposite boundaries of the discharge port 15 towards the discharge port 15. However, since this slope affects the overall thickness of the base plate 11, the drop is generally within 15mm, meaning the top surface height of the base 1 gradually decreases from the adjacent and opposite sides of the discharge port 15 to the discharge port 15, and the decrease in height is less than 15mm. Figure 5 In the embodiment shown, the discharge port 15 is located near the first side 13 of the base plate 11, with a drop of 10mm, which can also achieve a good liquid-assisted drainage effect.

[0098] In one embodiment, the partitions are a plurality of spacers 51 located between the first set of side plates and the base 1. The spacers 51 extend along a second direction or along a first direction and are located at the edge of the base 1, for example, near the edge of the first side 13 or the second side 14. Of course, as a preferred embodiment, in order to maintain the stability of the plurality of side plates, two spacers 51 are arranged opposite each other, and preferably are located on the base plate 11 adjacent to a pair of first side 13, or adjacent to the second side 14.

[0099] As a preferred embodiment, the spacer 51 is connected to the top surface of the base plate 11 and can be fixed to the top surface of the base plate 11 by bonding, bolting or other means, without limiting the specific implementation of the spacer 51.

[0100] exist Figure 6 and Figure 7 In the embodiment shown, two spacers 51 are located on a pair of second sides 14 of the base 1, that is, adjacent to the third side plate 4, supporting the first set of side plates, and forming an accommodating space 16 between the first set of side plates and the base plate 11, in which the heating plate or other accessories can be placed, that is, between the two spacers 51.

[0101] In another embodiment, the two spacers 51 can be connected to the inner surfaces of the first side plate 2 and the second side plate, for example, to the top or bottom surface of the first side plate 2, or to the two side edges of the first side plate 2 near the two third side plates 4. After the top surface of the folded base of the first side plate 2 is folded, the two spacers 51 abut against the base plate 11 to support the first side plate 2. Of course, multiple spacers can also be installed on the inner surfaces of the first side plate and the second side plate respectively. Regardless of the top surface of the folded base of either the first side plate or the second side plate, preferably the spacers 51 on the side plate stacked on the top surface of the base abut against the base plate 11, which can form the accommodating space 16.

[0102] Of course, the spacer 51 can also be set as multiple vertically spaced spacers. In order to stably support the first set of side plates, at least three spacers need to be set on the top surface of the base plate 11. The three spacers form a triangular structure to stably support the first set of side plates.

[0103] In addition, the spacer 51 can also be configured in a curved shape, such as a U-shape extending along the edge of the base plate 11, which can stably support the first side plate 2.

[0104] In the second embodiment, as Figure 9 and Figure 10 As shown, the partition consists of two steps 52 on the top surface of the base plate 11. The two steps 52 extend along the second direction and are located on the two second sides 14 of the base plate 11, that is, on the same side as the two third side plates 4.

[0105] Of course, in another embodiment, the two steps 52 can also be set on the base plate 11 near the two first side plates 2, avoiding the discharge port 15. Alternatively, more steps 52 can be set at the edge of the base plate 11.

[0106] In the third embodiment, as Figures 11 to 15 As shown, the first side plate 2 has first engaging portions 21 on both sides facing the two third side plates 4, and the first engaging portions 21 engage with the two third side plates 4. Specifically, the outer surfaces of the two first engaging portions 21 have slots 23, which are open towards the third side plates 4. The inner surfaces of the two third side plates 4 facing the first side plate 2 have locking blocks 41, and when the container 100 is in the open state, the locking blocks 41 are located in the slots 23.

[0107] Furthermore, the inner side of the first engaging portion 21 extends inward beyond the inner side of the first side plate 2. In other words, the inner side of the first engaging portion 21 protrudes beyond the inner side of the first side plate 2. The partition is the portion of the inner side of the first engaging portion 21 that protrudes beyond the inner side of the first side plate 2. This portion of the first engaging portion 21 that protrudes beyond the inner side of the first side plate 2 is defined as the first protrusion 211. When the container 100 is folded, the inner side of the first side plate 2 faces the bottom plate 11, and the first protrusion 211 of the first engaging portion 21 abuts against the bottom plate 11, thus spacing the first side plate 2 and the bottom plate 11 apart.

[0108] Furthermore, the second side plate 3 is provided with a second engaging part 31 on each side facing the two third side plates 4, and the second engaging part 31 is used to engage with the two second side plates 3.

[0109] The outer side of the second engaging portion 31 is also provided with a slot 23, and the inner side also protrudes from the inner side of the second side plate 3. The portion of the second engaging portion 31 that protrudes from the inner side of the second side plate 3 is defined as the second protrusion 311. To facilitate folding and reduce the gap between the second side plate 3 and the first side plate 2, the outer side of the first engaging portion 21 is provided with a recessed clearance groove 22. When the container 100 is folded, the second protrusion 311 of the second engaging portion 31 is located within the clearance groove 22, thereby allowing the second side plate 3 and the first side plate 2 to fit together, reducing the folding space.

[0110] Of course, as a preferred embodiment, the first side plate 2 and the second side plate 3 have the same shape, the second engaging part 31 has the same shape as the first engaging part 21, and the outer side of the second engaging part is also provided with a clearance groove.

[0111] If the first side plate 2 is preferably stacked on the top surface of the base, and the second side plate is stacked on the top surface of the first side plate, then the first protrusion 211 of the first engaging part 21 abuts against the bottom plate 11 so that the first side plate 2 and the bottom plate 11 are spaced apart, and the second protrusion 311 of the second engaging part 31 is located in the relief groove 22 of the first engaging part.

[0112] If the second side plate is preferentially stacked on the top surface of the base, and the first side plate is stacked on the top surface of the second side plate, then the second protrusion 311 of the second engaging part 31 abuts against the top surface of the base plate, so that the second side plate and the base plate are spaced apart to form an accommodating space, and the first protrusion of the first engaging part is located in the clearance groove of the second engaging part.

[0113] In other words, this utility model does not limit the folding order of the first side plate and the second side plate.

[0114] The second engaging part 31 and the second side plate 3 are integrally formed. The first engaging part 21 and the first side plate 2 are integrally formed, that is, the first side plate 2 and the first engaging part 21 have the same overall shape as the second side plate 3 and the second engaging part 31, which facilitates the processing of the two side plates.

[0115] The two third side plates 4 are provided with buckles on both sides along the second direction to engage with the first engaging part 21 and the second engaging part 31, so as to facilitate the engagement of the two third side plates 4 with the first side plate 2 and the second side plate 3.

[0116] It should be understood that the first side plate 2 and the second side plate 3 can also be detachably connected in other ways, and are not limited to the interlocking method described above. Furthermore, the outer surfaces of the first side plate 2 and the second side plate 3 are the exterior surfaces of the container 100 when it is open, and the inner surfaces are the interior surfaces of the container 100. Similarly, the outer surfaces of the first engaging portion 21 and the second engaging portion 31 are also the exterior surfaces of the container 100 when it is open, while the inner surfaces are the interior surfaces.

[0117] It should be understood that the first side panel 2 and the second side panel 3 can also be long side panels, while the third side panel 4 can be a short side panel. One of the first side panel 2 and the second side panel is the side panel that is folded first in the folding sequence, that is, the side panel located on the top surface of the bottom plate 11 after folding. The partition can be set on the preferred folded side panel. The height D of the partition strip 51, step 52, or first engaging part 21 protruding from the inner side surface of the first side panel 2 or the second side panel is 10mm-15mm. When the container 100 is folded, the partition strip 51 or step 52 can support the first side panel 2 or the second side panel, so that there is at least a height D between it and the top surface of the bottom plate 11. This height space, plus the space formed by the slope of the bottom plate 11, can accommodate and protect the heating plate and other accessories included with the box for storage and safety after the box is folded.

[0118] In another embodiment, such as Figure 17-26 As shown, the container 100 is basically the same as the above embodiment, also including a base 1, a first side plate 2, a second side plate 3, a pair of oppositely arranged third side plates 4, a lid 6 and a heating plate. The base 1 includes a bottom plate 11 and two extension plates 12. The bottom plate 11 is rectangular and has a pair of oppositely arranged first side edges 13 and a pair of oppositely arranged second side edges 14. The first side edges 13 extend along a first direction and the second side edges 14 extend along a second direction.

[0119] Two extension plates 12 are respectively connected to a pair of second side plates 14 and extend upward.

[0120] The first side plate 2, the second side plate 3, and the pair of third side plates 4 are foldably connected to the four sides of the base 1. Specifically, the first side plate 2 and the second side plate 3 are short side plates and are arranged opposite each other, while the two third side plates 4 are long side plates and are arranged opposite each other. The first side plate 2 and the second side plate 3 are respectively hinged to a pair of first side edges 13 of the base plate 11, and the pair of opposite third side plates 4 are respectively hinged to the top surfaces of two extension plates 12. The two extension plates 12 are mainly used to facilitate the folding of the pair of third side plates 4 inward. The folding direction of the first side plate 2, the second side plate 3, and the third side plate 4 to the base 1 is not restricted.

[0121] In the folded state, the first side plate 2 is located on the top surface of the base 1, the second side plate 3 is located on the top surface of the first side plate 2, and a pair of third side plates 4 are stacked sequentially on the top surface of the second side plate 3. From bottom to top, they are the base plate 11, the first side plate 2, the second side plate 3, and a pair of third side plates 4. Of course, in other embodiments, in the folded state, the second side plate is located on the top surface of the base, the first side plate is located on the top surface of the second side plate, and the third side plate is located on the top surface of the second side plate. That is to say, the folding order of the first and second side plates is not limited.

[0122] The first side plate 2 has a first engaging portion 21 on each side facing the two third side plates 4, and the second side plate 3 has a second engaging portion 31 on each side facing the two third side plates 4. The difference is that the two third side plates 4 have a protruding first engaging portion 42 on the side closer to the first side plate 2, and a protruding second engaging portion 43 on the side closer to the second side plate 3.

[0123] When the container 100 is in the unfolded state, the two first snap-fit ​​parts 42 and the two first snap-fit ​​parts 21 of the first side plate 2 snap-fit ​​together, and the two second snap-fit ​​parts 43 and the two second snap-fit ​​parts 31 of the second side plate 3 snap-fit ​​together.

[0124] In the folded state, the first side plate 2 is located on the top surface of the base 1, the second side plate 3 is located on the top surface of the first side plate 2, and the first third side plate 4 is stacked on the top surface of the second side plate 3. The first snap-fit ​​portion 42 and the second snap-fit ​​portion 43 of the third side plate 4 abut against the top surface of the second side plate 3, so that a gap is formed between the first third side plate 4 and the second side plate 3.

[0125] The second third side plate 4 is stacked on the top surface of the first third side plate 4, and the first snap-fit ​​portion 42 and the second snap-fit ​​portion 43 of the second third side plate 4 abut against the top surface of the first third side plate 4, so that a gap is also formed between the second third side plate 4 and the first third side plate 4.

[0126] As a preferred embodiment, the inner surfaces of the first latching portion 42 and the second latching portion 43 of the third side plate 4 are both concave arc surfaces facing outwards, and the inner surfaces of the two first engaging portions 21 and the two second engaging portions 31 are also concave arc surfaces facing inwards, and the arc radius of the first engaging portion 21, the arc radius of the second engaging portion 31, the arc radius of the first latching portion 42, and the arc radius of the second latching portion 43 are the same.

[0127] When the container 100 is in the unfolded state, the arc surfaces of the two first latching parts 42 and the arc surfaces of the two first engaging parts 21 are joined to form an approximately 1 / 4 arc corner 214, and the arc surfaces of the two second latching parts 43 and the arc surfaces of the two second engaging parts 31 are joined to form an approximately 1 / 4 arc corner 214. That is to say, the four corners of the container 100 are seamlessly connected rounded corners 214.

[0128] Collapsible containers 100, especially those for liquid packaging, are very popular in the market and are increasingly being adopted. When used as a liquid packaging solution, collapsible containers 100, combined with disposable liners and filling and drain valves, can effectively protect the hygiene and safety of goods. Therefore, collapsible container 100 packaging solutions are very suitable for industries with high hygiene requirements, such as food and cosmetics. The liner is in a vacuum adsorption state before filling and gradually unfolds and adheres to the inner wall of the container 100 during the liquid filling process. Because the internal space of the container 100 is a square structure, it is difficult to adhere the unfolded liner to the four corners formed by the four side panels. This is related to both the liner structure and the skill of the filling operation. The main purpose of this adhesion is to prevent gaps from forming between the large rounded corners of the liquid bag and the right-angle corners of the container 100, which could cause liquid sloshing during transportation and create a rubbing effect that could affect the safety of the liquid bag.

[0129] When container 100 is fully loaded, it often needs to be stacked for storage or transportation. Due to the structure of base 1, the area near the corner where the first side plate 2, the second side plate 3, and the two third side plates 4 connect needs to bear most of the weight of the upper container. When container 100 is transported fully loaded, multiple containers 100 are often stacked and loaded onto the vehicle, with the stacked containers 100 close together to reduce displacement during transportation. When the vehicle accelerates or decelerates suddenly, the violent shaking of the liquid can cause the four side plates of container 100 to bulge significantly. The bulging side plates will affect the tightly packed containers 100, forcing their side plates to concave inward, thus affecting the interlocking connection structure between the side plates of container 100 and threatening the safety of the cargo.

[0130] This utility model achieves this by rounding the four corners of the container 100, such as... Figure 27As shown, after testing, the rounded corners have strong bending resistance, which can improve the strength of the four side plates and make it easier to fit the liner bag after filling. Because this utility model improves the safety of full-load transportation of the liner bag, enhances the stacking and load-bearing stability of the container 100, and has a better ability to prevent liquid surges from impacting the seal, it comprehensively improves the reliability of the container 100 itself and can better protect the safety of the internal goods.

[0131] As a preferred embodiment, the arc radius of the first engaging portion 42 and the arc radius of the second engaging portion 43 are both specified. The arc radius of the first engaging portion 21 and the arc radius of the second engaging portion 31 range from 15mm to 40mm, specifically 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm, 30mm, 31mm, 32mm, 33mm, 34mm, 35mm, 36mm, 37mm, 38mm, 39mm, and 40mm.

[0132] More preferably, the arc radius of the first engaging portion 42 and the arc radius of the second engaging portion 43 are both 25 mm or 30 mm.

[0133] Of course, in some embodiments, only the inner surfaces of the two first latching portions 42 and the two first engaging portions 21 can be set as curved surfaces, and the radius of curvature of the two first latching portions 42 and the radius of curvature of the two first engaging portions 21 can be the same or different; they can be arcs or non-arcs. Alternatively, the inner surfaces of the two second latching portions 43 and the two second engaging portions 31 can be set as curved surfaces, and the radius of curvature of the two second latching portions 43 and the radius of curvature of the two second engaging portions 31 can be the same or different; they can be arcs or non-arcs. Alternatively, the two first latching portions 42 or the two second latching portions 43 can be curved surfaces, while the two second engaging portions 31 and the two first engaging portions 21 can be flat surfaces. Alternatively, the inner surfaces of the two first engaging portions 21 or the two second engaging portions 31 can be curved surfaces, and the inner surfaces of the two first latching portions 42 and the two second latching portions 43 can be curved surfaces. Of course, the curved surfaces do not need to be arcs.

[0134] In the embodiment shown in the figure, the engagement method of the first engaging portion 42 and the first engaging portion 21 is the same as the engagement method of the second engaging portion 43 and the second engaging portion 31.

[0135] Taking the implementation of the first latching part 42 and the first engaging part 21 as an example, the first latching part 42 includes a first latching block 423 and a first protrusion 422. The first protrusion 422 is connected to the inner side of the third side plate 4, and the inner side of the first latching block 423 and the first protrusion 422 are connected and form a first latching groove 421 with the first protrusion 422. The first latching groove 421 is open to the inner side of the container 100.

[0136] The first engaging part 21 includes a second engaging block 212, which is connected to the end of the first side plate 2 and forms a second engaging groove 213 with the end face of the first side plate 2 that is open to the outside.

[0137] When the container 100 is in the unfolded state, the second locking block 212 of the first locking part 21 is engaged in the first locking groove 421 of the first locking part 42, and the first locking block 423 of the first locking part 42 is engaged in the second locking groove 213 of the first locking part 42. The inner side of the first protrusion 422 and the inner side of the second locking part 31 are joined to form a rounded corner.

[0138] Of course, in other embodiments, the first engaging portion 21 and the first engaging portion 42 may also adopt other implementation methods, which are not necessarily the embodiments shown in the figure of this utility model, as long as the inner surfaces of the first engaging portion 21 and the second engaging portion 43 form rounded corners 214.

[0139] Of course, in other embodiments, the outer corners 215 on both sides of the first side plate 2, the second side plate 3, or the second side plate 3 can also be set as rounded corners 214.

[0140] The preferred embodiments of the present invention have been described in detail above, but it should be understood that, if necessary, aspects of the embodiments can be modified to utilize aspects, features, and concepts from various patents, applications, and publications to provide other embodiments.
