Description

TECHNICAL FIELD

[0001] The present application relates to the field of logistics transportation, in particular to a foldable container. BACKGROUND

[0002] The existing foldable storage container is generally assembled by two pairs of side plates and a base. The two pairs of side plates are foldable relative to the base, and the side plates and the base are kept upright by a locking mechanism fixed on the side plates to form a storage state of the container. Such a container not only serves as a transportation and packaging carrier, but also has a warehouse function, i.e. intermediate storage and end-of-line display and sale. Therefore, after the goods arrive at the destination, they can directly enter the sales area or the shelf for consumers to choose and purchase. However, the existing storage containers, whether integrated or foldable, generally only have the side plates foldable inward relative to the base. When the storage containers are stacked, the goods and commodities are in a relatively shielded state, and consumers or goods takers cannot pick up the goods through the side plates of the box, which further hinders and restricts the purchasing behavior of consumers.

[0081] Embodiments of the present application are described below with reference to the accompanying drawings.

[0082] The first embodiment of the present application relates to a foldable container 100. The foldable container 100 comprises a base 3, and two pairs of side plates, each pair of side plates is operatively foldable connected with the base 3, and two adjacent side plates are operatively detachably connected through a snap structure 5 and are operatively locked through a locking structure 6.

[0083] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , in this embodiment, the two pairs of side plates are a pair of long side plates 1 and a pair of short side plates 2, and one short side plate 2 is clamped between two long side plates 1. The structure of one pair of short side plates 2 can be the same or different, and the structure of one pair of long side plates 1 can be the same or different. In other embodiments, there can be no distinction between short side plates 2 and long side plates 1. The side edges of the short side plates 2 have protruding limit members 23, and the side edges of the long side plates 1 have grooves 13, the protruding limit members 23 can be embedded into the grooves 13 to form the snap structure 5, and the bottom of the short side plates 2 and the bottom of the long side plates 1 are hingedly connected with the base 3. When folding is needed, the short side plates 2 are tilted towards the inside of the foldable container 100, the protruding limit members 23 are separated from the grooves 13, the short side plates 2 are folded onto the base 3, and the long side plates 1 are also tilted towards the inside of the foldable container 100, and the long side plates 1 are folded onto the base 3. Understandably, in other embodiments, the side edges of the long side plates 1 can have protruding limit members, and the side edges of the short side plates 2 can have grooves, and in addition, the snap structure 5 is not limited to the structure shown in this embodiment, and other snap structures 5 in the art can be used. In this embodiment, the structure of one short side plate 2 is taken as an example, the short side plate 2 has a plate body 21 with an opening 20, and a door plate 22 hingedly connected with the plate body 21. In this embodiment, one short side plate 2 has a plate body 21 with an opening 20 and a door plate 22, and in other embodiments, both short side plates 2 can have a plate body 21 with an opening 20 and a door plate 22, or the long side plates 1 can have a plate body 21 and a door plate 22. The door plate 22 is hingedly connected with the plate body 21, can be flipped to open the opening 20 towards the outside of the foldable container 100, and can be flipped to close the opening 20 towards the inside of the foldable container 100, the plate body 21 is hingedly connected with the base 3, and is detachably connected with the two adjacent side plates, and the hinging axis of the door plate 22 and the plate body 21 is parallel to the hinging axis of the plate body 21 and the base 3.

[0084] As shown in Figure 5 , Figure 6 and Figure 7 , the foldable container 100 further comprises a handle structure 4 movably connected with the door plate 22, as shown in Figure 6 , the handle structure 4 is operatively locked with the plate body 21 and the door plate 22; as shown in Figure 7In the embodiment, the handle structure 4 is operable to move towards the first direction to the first position to unlock the plate body 21 from the adjacent side plate, and the handle structure 4 is operable to move towards the second direction to the second position to unlock the plate body 21 from the door plate 22.

[0085] Further, the first direction is towards the direction away from the base 3, and the second direction is towards the direction towards the base 3. That is, in the embodiment, when the foldable container 100 is unfolded, the handle structure 4 is in the initial position, at which the short side plate 2 is engaged with the two adjacent long side plates 1 and is locked together by the locking structure 6, and the door plate 22 is engaged with the plate body 21 and is locked together. The handle structure 4 in the initial position is pulled towards the first direction, i.e. upwards, to the first position, and the plate body 21 is unlocked from the long side plate 1. The handle structure 4 in the initial position is pulled towards the second direction, i.e. downwards, to the second position, and the plate body 21 is unlocked from the door plate 22. Understandably, in other embodiments, the first direction is towards the direction towards the base 3, and the second direction is towards the direction away from the base 3.

[0086] From the above, it can be seen that the side plates are foldably arranged with the base 3 to achieve the foldability of the container. Meanwhile, at least one side plate has the door plate 22 and the plate body 21 with the opening 20, and the door plate 22 is unlocked from the plate body 21 by the handle structure 4 to be flipped towards the outside of the foldable container 100 to open the opening 20, so that the product or goods in the foldable container 100 can be seen or taken through the opening 20 in the case of stacking of the foldable containers 100, which is more convenient. When the goods do not need to be taken, the door plate 22 and the plate body 21 can be locked by the handle structure 4 to prevent the goods from falling. In addition, the two adjacent side plates are detachably connected by the engaging structure 5 and are locked together by the locking structure 6 when the foldable container 100 is used, which is stable in structure. When folding is needed, the two adjacent side plates are unlocked by the handle structure 4 to be folded towards the base 3. Further, the door plate 22 and the plate body 21 are locked and unlocked by the handle structure 4, and the two adjacent side plates are unlocked by the handle structure 4 to fold the foldable container 100, which is more compact and convenient.

[0087] The implementation details of the embodiment will be described in detail below. The following details are provided for the convenience of understanding and are not essential for implementing the embodiment.

[0088] In addition, as shown in Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , Figure 6 and Figure 9 are the states when the locking structure 6 is locked, Figure 7 and Figure 10For the state of unlocking the locking structure, the locking structure 6 comprises: a lock tongue 61 arranged on the plate body 21, and a lock catch 62 arranged on the long side plate 1. The lock catch 62 is operable to be buckled on the lock tongue 61, and the handle structure 4 is operable to move towards the first direction (upward) to push the lock catch 62 off the lock tongue 61.

[0089] Further, the lock tongue 61 is a protruding piece upward as shown in Figure 9 and Figure 10 , one end of the lock catch 62 is embedded on the long side plate 1, and the other end of the lock catch 62 has a clamping groove 620, the protruding piece is operable to be clamped into the clamping groove 620 to realize the locking of the plate body 21 and the long side plate 1. As shown in Figure 7 and Figure 10 , the handle structure 4 is operable to move towards the first direction (upward) to push the other end of the lock catch 62 to make the lock catch 62 rise from the protruding piece. The lock catch 62 is a long strip, which can be elastic, such as a rubber strip with elasticity. When the handle structure 4 pushes the other end of the lock catch 62 upward, the lock catch 62 bends upward to be separated from the protruding piece. In other embodiments, the locking structure 6 can also have other structures, such as arranging an upward opening slot on the plate body 21, and arranging a strip-shaped lock on the long side plate 1, one end of the strip-shaped lock has a downward protrusion which can be nested in the slot to realize the locking, and when unlocking is needed, the handle structure 4 can be used to push the strip-shaped lock to lift, so that the protrusion of the strip-shaped lock is pulled out of the slot.

[0090] Further, as shown in Figure 1 , Figure 11 , Figure 12 and Figure 13As shown, the handle structure 4 comprises: a handle body 41, and at least a pair of oppositely arranged first return member 42 and third return member 45. The first return member 42 and the third return member 45 are elastic rubber strips or the like. The handle body 41 is operable to unlock the plate body 21 from the long side plate 1, and operable to unlock the plate body 21 from the door plate 22. The door plate 22 has a cavity 220 for mounting the handle body 41, and a hand holding portion of the handle body 41 is exposed from the cavity 220. One end of the first return member 42 and the third return member 45 are connected to the handle body 41, and the other end of the first return member 42 and the third return member 45 are respectively abutted against a first abutment wall surface 221 and a second abutment wall surface 222 on the door plate 22, which are respectively located on two sides of the handle body 41 in the height direction. That is, the first return member 42 is connected to the upper side of the handle body 41 and abutted against the first abutment wall surface 221 located above the handle body 41, and the third return member 45 is connected to the lower side of the handle body 41 and abutted against the second abutment wall surface 222 located below the handle body 41. The first return member 42 abutted against the first abutment wall surface 221 is operable to provide a restoring force to the handle body 41 in the direction of the base 3, and the third return member 45 abutted against the second abutment wall surface 222 is operable to provide a restoring force to the handle body 41 in the direction away from the base 3. That is, the handle body 41 in the initial position is pulled upward, the handle body 41 pushes the lock catch 62 upward to disengage the lock tongue, the handle body 41 pushes the first return member 42 connected to the upper side thereof to abut against the first abutment wall surface 221, and the handle body 41 is released, the first return member 42 connected to the upper side thereof pushes the handle body 41 to reset to the initial position. Similarly, the handle body 41 is pushed downward, the third return member 45 connected to the lower side thereof is pushed to abut against the second abutment wall surface 222, the handle body 41 is released, and the third return member 45 connected to the lower side thereof pushes the handle body 41 to reset to the initial position.

[0094] In addition, as shown in Figure 6 , Figure 7 , Figure 9 and Figure 10 , the handle body 41 extends along the length direction of the door panel 22 and extends below the lock catch 62, the handle body 41 is operable to move towards the first direction to push the lock catch 62 away from the lock bolt 61. The side edges of the two long side panels 1 are both connected with the lock catch 62, the two ends of the handle body 41 are both below the lock catch 62, and in the process of being pushed upwards, the two lock catches 62 are simultaneously pushed upwards to separate from the corresponding lock tongue.

[0095] Further, as shown in Figure 1 , Figure 14 , Figure 15 and Figure 16 , wherein Figure 15 is the state of the handle body 41 in the initial position, Figure 15In the state that the handle body 41 is pulled down, the long side plate 1 has a flange 11 extending to the side where the short side plate 2 is located, and the flange 11 covers part of the outer surface of the plate body 21. The flange 11 has a notch 12. The handle body 41 is clamped between the plate body 21 and the flange 11 to lock the plate body 21 and the door plate 22. The flange above the notch 12 limits the handle body 41. The handle body 41 can be operated to move towards the second direction (downward) so that the part of the handle body 41 clamped between the plate body 21 and the flange 11 is located at the notch 12 to unlock the plate body 21 and the door plate 22. That is, when the handle structure 4 is in the initial position, the handle body 41 is located between the plate body 21 and the flange 11, and the door plate 22 is locked and cannot be flipped. The handle body 41 is pulled down so that both ends of the handle body 41 slide to the notch 12, and both ends of the handle body 41 are exposed. The flange 11 cannot block the handle body 41, and the door plate 22 and the plate body 21 are unlocked. The door plate 22 can be flipped out of the foldable container 100 to open the opening 20.

[0096] In addition, as shown in Figure 6 、 Figure 7 、 Figure 17 and Figure 18 , when the door plate 22 closes the opening 20, the door plate 22 and the plate body 21 are connected by engagement, that is, the side edge of the door plate 22 has a protrusion 24, and the side wall of the opening 20 has a groove 25. The protrusion 24 is embedded in the groove 25, and when the door plate 22 is flipped out, the protrusion 24 is separated from the groove 25. The door plate 22 and the plate body 21 are connected by double hinge shafts. The upper hinge shaft 72 is sleeved on the bottom of the door plate 22 and the connecting piece 71, and the lower hinge shaft 73 is sleeved on the top of the plate body 21 and the connecting piece 71. When the door plate 22 is flipped out of the foldable container 100, the connecting piece 71 rotates around the lower hinge shaft 73, and the door plate 22 rotates around the upper hinge shaft 72. The door plate 22 can be closer to the plate body 21, and after being flipped, the door plate 22 is approximately parallel to the plate body 21, so that the opening 20 is completely opened and is not disturbed by the door plate 22. The door plate 22 also does not occupy too much space of the foldable container 100.

[0097] The second embodiment of the present application relates to a foldable container 200. The second embodiment is basically the same as the first embodiment, and the main difference is that in the first embodiment, the handle body 41 directly pushes the locking piece 62 to unlock the long side plate 1 and the plate body 21, and the locking between the door plate 22 and the plate body 21 is limited by the flange 11 of the long side plate 1 and the plate body 21 to limit the handle body 41. In the second embodiment of the present application, as shown in Figure 19 and Figure 20As shown, the plate body 21 has a main frame plate 211, a follower 212 movably arranged on the main frame plate 211, and a second reset member 213 which can be a spring or a resilient piece. The main frame plate 211 is hingedly connected with the base 3 and connected with two adjacent long side plates 1. The structure of the connection between the main frame plate 211 and the two long side plates 1 is the same as that in the first embodiment, and the main frame plate 211 is locked by the engagement structure 5 and the locking structure 6, which will not be described in detail here. The door plate 22 is hingedly connected with the main frame plate 211, and the structure of the connection between the door plate 22 and the main frame plate 211 is the same as that in the first embodiment, which will not be described in detail here. The opening 20 is formed on the main frame plate 211. The two ends of the second reset member 213 abut against the follower 212 and the main frame plate 211 respectively, and the second reset member 213 operatively provides the follower 212 with a restoring force towards the base 3. The handle body 41 operatively moves towards the first direction (upward) to push the follower 212 to push the locking piece 62 away from the locking tongue piece 61. The handle body 41 cooperatively connects with the follower 212 to lock the main frame plate 211 and the door plate 22. The handle body 41 operatively moves towards the second direction to disconnect with the follower 212 to unlock the main frame plate 211 and the door plate 22. When the handle body 41 is pulled upward from the initial position, the handle body 41 pushes the follower 212 to slide upward along the main frame plate 211, the follower 212 pushes the locking piece 62 away from the locking tongue piece 61, the follower 212 pushes the second reset member 213, the handle body 41 is released, and the second reset member 213 provides the follower 212 with a downward pushing force to push the handle body 41 back to the initial position.

[0098] Further, as shown in Figure 21 、 Figure 22 、 Figure 23 、 Figure 24 、 Figure 25 、 Figure 26 wherein Figure 22 and Figure 25 are the states of the handle structure in the initial position, Figure 23 and Figure 26In the state of the handle structure after being pulled up, the driven member 212 has a driven main body part 2121 and a protruding part 2122 connected with the driven main body part 2121. The protruding part 2122 extends to below the lock catch 62, and the protruding part 2122 is operable to push the lock catch 62 away from the latch part 61. The bottom end of the driven main body part 2121 has a stop part 2125 extending towards the base 3, and the stop part 2125 is opposite to the main body frame along the thickness direction of the first side plate to form a limiting cavity 2123. One end of the handle body 41 is located in the limiting cavity 2123 and is located on the side of the stop part 2125 towards the main body frame plate 211 and the door plate 22. One end of the handle body 41 is operable to slide out of the limiting cavity 2123 to unlock the main body frame plate 211 and the door plate 22. Specifically, when the handle body 41 is in the initial position or moves upward from the initial position, one end of the handle body 41 is located in the limiting cavity 2123, and the top of the limiting cavity 2123 has an embedding groove, and the handle body 41 has a protrusion 44 embedded in the embedding groove. Since the driven member 212 is on the main body frame plate 211, one end of the handle body 41 is located in the limiting cavity 2123, and the stop part 2125 limits the handle body 41, so that the handle body 41 and the door plate 22 cannot be flipped out of the foldable container 200, thereby achieving locking of the door plate 22. When the handle body 41 is pulled downward from the initial position, one end of the handle body 41 slides out of the lower end of the limiting cavity 2123, and is separated from the driven member 212. The stop part 2125 of the limiting cavity 2123 cannot limit the handle body 41, and the door plate 22 is unlocked from the main body plate 21, and the handle body 41 and the door plate 22 can be flipped out of the foldable container 200.

[0099] As shown in Figure 21 , Figure 22 , Figure 23 , Figure 27 , Figure 28 , Figure 29 wherein Figure 22 and Figure 28 are the state of the handle structure in the initial position, Figure 23 is the state of the handle structure after being pulled up, Figure 29 is the state of the handle structure after being pulled down, the side wall of the driven main body part 2121 has a protruding hook body 2124, and the main body frame plate 211 is provided with a longitudinally extending channel 2110 for the driven main body part 2121 to slide up and down. The channel wall of the channel 2110 has a sliding groove for the hook body to embed. When the driven main body part 2121 slides up and down, the channel 2110 limits the sliding direction of the driven main body part 2121, and the hook body 2124 slides along the sliding groove.
