Plastic-free logistics box and its recycling method

Abstract

This invention discloses a plastic-free logistics box and its recycling method. By placing multiple locking cards, each including a blocking part, a connecting part, and a first locking tongue, inside the box, the unfolded area of ​​the box is not increased. The connecting part is connected to the blocking part, with the size of the connecting part not exceeding the size of the through hole, while the size of the blocking part is larger than the size of the through hole, allowing the locking cards to be engaged within the through hole. Simultaneously, the first locking tongue is detachably connected to the connecting part, and its size matches that of the first locking hole. Passing the first locking tongue through the through hole and embedding it into the first locking hole seals the plastic-free logistics box. The entire sealing process eliminates the need for plastic tape, avoiding plastic waste pollution and facilitating user convenience. Furthermore, after opening, only new locking cards are needed to reuse the plastic-free logistics box. Without increasing the product's unfolded area, the box can be reused multiple times, saving costs and reducing the box's weight by 30%.

The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0084] like Figures 1-3 As shown, this embodiment provides a plastic-free logistics box, which includes a first side plate 1, a second side plate 2, a third side plate 3 and a fourth side plate 4 connected in sequence, as well as a first cover plate 5, a first lock hole 18, a second cover plate 6, a through hole 21 and a locking card 17.

[0085] The first cover plate 5 is disposed on one side of the first side plate 1, and a first lock hole 18 is provided at the connection between the first cover plate 5 and the first side plate 1.

[0086] One end of the second cover plate 6 is connected to one end of the third side plate 3. The second cover plate 6 has a through hole 21, which is elongated in shape. However, those skilled in the art should understand that the shape of the through hole 21 is not limited to elongated; other shapes are also acceptable. The other end of the second cover plate 6 has a clearance hole 20, with anti-theft lines 23 on both sides of the clearance hole 20 to provide protection and prevent malicious opening of the box. The size of the clearance hole 20 is not smaller than the size of the first locking tongue 173. When sealing the box, the second cover plate 6 covers the first cover plate 5, and the first locking tongue 173 passes through the clearance hole 20 and is inserted into the first locking hole 18.

[0087] The locking card 17 is made of paper or other environmentally friendly materials. There are multiple locking cards 17. The locking card 17 is movable inside the box, which is convenient to take out and replace flexibly, so as to realize the recycling of plastic-free logistics boxes.

[0088] Furthermore, in this embodiment, the locking card 17 includes a blocking portion 171, a connecting portion 172, and a first locking tongue 173.

[0089] The first latch 173 is detachably connected to the connecting part 172. The size of the first latch 173 matches the size of the first lock hole 18 and is smaller than the size of the connecting part 172.

[0090] The first locking tongue 173 passes through the through hole 21 along with the connecting part 172 and is embedded in the first locking hole 18 to seal the plastic-free logistics box.

[0091] Furthermore, in this embodiment, the locking card 17 also includes a tear-out hole 174, which is located at the connection between the first locking tongue 173 and the connecting portion 172. By providing the tear-out hole 174, the user can place their hand into the tear-out hole 174 to grasp the first locking tongue 173, making it easy to tear the first locking tongue 173 off the connecting portion 172, thereby quickly removing the locking card 17, improving opening efficiency, and facilitating user operation.

[0092] like Figures 1-3 As shown, the plastic-free logistics box also includes a first base plate 9, a second lock hole 19, a second base plate 10, and a second lock tongue 22.

[0093] The first base plate 9 is located on the other side of the first side plate 1, and its size is the same as that of the first cover plate 5 and its position corresponds to that of the first cover plate 5.

[0094] One end of the second base plate 10 is connected to the other end of the third side plate 3. Its size is the same as that of the second cover plate 6 and its position corresponds to that of the second cover plate 6.

[0095] The second keyhole 19 is located at the connection between the first side plate 1 and the first bottom plate 9. In this embodiment, the shape, size and other parameters of the second keyhole 19 are the same as those of the first keyhole 18.

[0096] The second latch 22 is located at the other end of the second base plate 10. Anti-theft lines 23 are also provided on both sides of the second latch 22, which can play a protective role and prevent malicious opening of the box during transit. The size of the second latch 22 matches the size of the second lock hole 19. When sealing the box, the second latch 22 can be inserted into the second lock hole 19 and locked. In this embodiment, the shape, size and other parameters of the second latch 22 are the same as those of the first latch 173.

[0097] like Figures 1-3 As shown, the plastic-free logistics box also includes a third cover plate 7, a fourth cover plate 8, a third bottom plate 11, and a fourth bottom plate 12.

[0098] The third cover plate 7 is located at one end of the second side plate 2, and the third bottom plate 11 is located at the other end of the second side plate 2, that is, the two are symmetrically arranged with respect to the second side plate 2. The third cover plate 7 is provided with a first folding plate 13 near the first cover plate 5, and the third bottom plate 11 is provided with a third folding plate 15 near the first bottom plate 9.

[0099] The fourth cover plate 8 is located at one end of the fourth side plate 4, and the fourth bottom plate 12 is located at the other end of the fourth side plate 4, that is, the two are symmetrically arranged with respect to the fourth side plate 4. The fourth cover plate 8 is provided with a second folding plate 14 away from the second cover plate 6, and the fourth bottom plate 12 is provided with a fourth folding plate 16 away from the second bottom plate 10.

[0100] The dimensions of the first folding plate 13 and the second folding plate 14 after splicing match the dimensions of the first lock hole 18. When sealing the box, the first folding plate 13 and the second folding plate 14 are spliced ​​together and folded together 90 degrees to close the first lock hole 18.

[0101] The dimensions of the third fold plate 15 and the fourth fold plate 16 after splicing match the dimensions of the second lock hole 19. When sealing the box, the third fold plate 15 and the fourth fold plate 16 are spliced ​​together and folded together 90 degrees to close the second lock hole 19.

[0102] like Figure 4 and Figure 5 As shown, this embodiment also provides a method for recycling plastic-free logistics boxes, which uses the aforementioned plastic-free logistics boxes and includes a sealing operation and a reuse operation after opening the box. The sealing operation includes the following steps:

[0103] First step (S1): Remove the locking card 17 from the plastic-free logistics box;

[0104] The second step (S2) is to cover the first cover plate 5;

[0105] In the third step (S3), the connecting part 172 and the first locking tongue 173 are passed through the through hole 21;

[0106] Fourth step (S4): Cover with the second cover plate 6;

[0107] Fifth step (S5): Insert the first latch 173 into the first lock hole 18.

[0108] like Figure 5 As shown, the unpacking and reuse process includes the following steps:

[0109] The sixth step (S6) involves pulling the first bolt 173 out of the first keyhole 18;

[0110] Step 7 (S7): Open the second cover plate 6;

[0111] In the eighth step (S8), the connecting part 172 and the first locking tongue 173 are pulled out from the through hole 21;

[0112] Ninth step (S9): Open the first cover plate 5;

[0113] Step 10 (S10): Repeat steps 1 through 5.

[0114] This embodiment of the plastic-free logistics box uses multiple locking cards 17, each including a blocking part 171, a connecting part 172, and a first locking tongue 173, placed inside the box. This eliminates the need to increase the box's unfolded area. The connecting part 172 connects to the blocking part 171, with the size of the connecting part 172 not exceeding the size of the through hole 21, while the size of the blocking part 171 is larger than the through hole 21. This allows the locking cards to be secured within the through hole 21. Simultaneously, the first locking tongue 173 is detachably connected to the connecting part 172, and its size matches the first locking hole 18. Passing the first locking tongue 173 through the through hole 21 and embedding it into the first locking hole 18 seals the plastic-free logistics box. The entire sealing process eliminates the need for plastic tape, preventing plastic waste pollution and simplifying user operation. Furthermore, after opening, the box can be reused simply by replacing the locking cards. Without increasing the product's unfolded area, the box can be reused multiple times, saving costs and reducing its weight by 30%.

[0115] It should be noted that in the claims and specification of this patent, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
