[0022] The third limiting structure is located behind the second limiting structure, and when the second limiting structure is in an unlocked state, the third limiting structure is used to stop with the first limiting structure to prevent the inner box from completely sliding out of the outer box;

[0023] Furthermore, when the third limiting structure abuts against the first limiting structure, the window is at least partially exposed to the outside of the outer box.

[0024] The present invention has at least the following advantages or beneficial effects:

[0025] The storage box provided by the present invention comprises: an outer box and an inner box, the front end surface of the outer box has an opening connecting the inside and the outside, the outer box comprises a first bottom surface and a first top surface, a first limiting structure is arranged on the inner wall of the first bottom surface, and in the up-down direction, the distance between the top surface of the first limiting structure and the inner wall of the first top surface is L1; the inner box comprises a second bottom surface and a second top surface, and a window connecting the inside and the outside is arranged on the second top surface; a second limiting structure is arranged on the outer wall of the second bottom surface, and in the up-down direction, the distance between the bottom surface of the second limiting structure and the outer wall of the second top surface is L2, and L2 is less than or equal to L1, so that the inner box can move vertically to a locked state and an unlocked state relative to the outer box; in the locked state, the bottom surface of the second limiting structure is lower than the top surface of the first limiting structure, and the first limiting structure is located on the movement path of the second limiting structure to prevent the inner box from moving toward the opening side relative to the outer box; in the unlocked state, the bottom surface of the second limiting structure is higher than or flush with the top surface of the first limiting structure, so that the second limiting structure can pass over the first limiting structure and leave the opening.

[0026] When in use, the inner box is located inside the outer box, and the inner box can hold materials. Under the obstruction of the first top surface, the materials cannot escape from the window. When the user needs to take the materials, he can hold the outer box with his right hand and the inner box with his left hand, and then pull the inner box upwards, so that the inner box is switched to the unlocked state, and the inner box can be pulled forward to pull the inner box out of the outer box and expose the window. If there is no action of pulling the inner box upward, the inner box is in a locked state, and the first limiting structure stops and limits the second limiting structure, and the inner box cannot be pulled out. Therefore, special opening steps are required to remove the inner box to prevent children from accidentally opening the storage box and accidentally eating the materials in the inner box. In addition, when there are no children, that is, when the user does not need a child lock, the outer box can be flipped up and down. When combined with the inner box, the first limiting structure and the second limiting structure are staggered, one up and one down, and the first limiting structure and the second limiting structure have no limit effect, and the inner box can be opened at will, and the child lock is invalid. Therefore, the user can flexibly switch the use mode. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] Example 1

[0054] like Figure 1 - Fig. 9 As shown, the storage box provided by the present invention can be used to hold laundry beads.

[0055] like Figure 1 - Figure 3 As shown, the storage box includes: an outer box 100 and an inner box 200, and the inner box 200 is placed in the outer box 100. The inner box 200 and the outer box 100 are both roughly rectangular as a whole.

[0056] like Figure 2 As shown, the front end surface of the outer box 100 has an opening communicating with the inside and outside, and the inner box 200 enters the outer box 100 through the opening. The outer box 100 includes a first bottom surface 110 and a first top surface 120. In normal use, the first bottom surface 110 faces downward and the second top surface 220 faces upward to place the storage box.

[0057] The inner wall of the first bottom surface 110 is provided with a first limiting structure 130, which has a certain height and acts as a stop. In the vertical direction, the distance between the top surface of the first limiting structure 130 and the inner wall of the first top surface 120 is L1.

[0058] like Figure 3 and Figure 4 As shown, the inner box 200 includes a second bottom surface 210 and a second top surface 220. In conventional use, the second bottom surface 210 faces downward and the second top surface 220 faces upward. The second top surface 220 is provided with a window 230 connecting the inside and the outside for taking and placing materials. A second limiting structure 240 is provided on the outer wall of the second bottom surface 210, and the second limiting structure 240 is used to stop and limit with the first limiting structure 130. In the up and down directions, the distance between the bottom surface of the second limiting structure 240 and the outer wall of the second top surface 220 is L2, and L2 is less than or equal to L1, so that the inner box 200 can move vertically relative to the outer box 100 to a locked state and an unlocked state, as shown in FIG. Figure 7 - Fig. 9 shown.

[0059] like Figure 7 As shown, in the locked state, that is, in the natural state (no human interference), the bottom surface of the second limiting structure 240 is lower than the top surface of the first limiting structure 130, and the first limiting structure 130 is located on the movement path of the second limiting structure 240 to prevent the inner box 200 from moving toward the opening side relative to the outer box.

[0060] like Figure 8 and Fig. 9As shown, in the unlocked state, the user needs to manually adjust the inner box 200, so as to switch the inner box 200 to the unlocked state, that is, to lift the inner box 200 upward relative to the outer box 100. The bottom surface of the second limiting structure 240 is higher than or flush with the top surface of the first limiting structure 130, and the first limiting structure 130 no longer stops the second limiting structure 240, so that the second limiting structure 240 can pass over the first limiting structure 130 and leave from the opening.

[0061] When in use, the inner box 200 is located inside the outer box 100, and materials can be placed in the inner box 200. Under the obstruction of the first top surface 120, the materials cannot escape from the window 230. When the user needs to take materials, he can hold the outer box 100 with his right hand and the inner box 200 with his left hand, and then pull the inner box 200 upwards, so that the inner box 200 is switched to the unlocked state, and the inner box 200 is pulled forward to pull the inner box 200 out of the outer box 100 and expose the window 230. If there is no action of pulling the inner box 200 upwards, the inner box 200 is in a locked state, and the first limiting structure 130 stops and limits the second limiting structure 240, so that the inner box 200 cannot be pulled out. Therefore, taking out the inner box 200 requires a special opening step to prevent children from accidentally opening the storage box and accidentally eating the materials in the inner box 200.

[0062] like Figure 5 As shown, in order to reduce the transportation cost of the storage box, the outer box 100 can be formed by folding and pasting the first cardboard. Similarly, the inner box 200 is formed by folding and pasting the second cardboard. The first cardboard and the second cardboard are flat. After the inner box 200 and the outer box 100 are pasted and formed, they can still be in a flat folded state, saving transportation costs. After being transported to the condensed bead factory, they only need to be manually folded to form a three-dimensional box structure without any equipment investment.

[0063] Specifically, the first paperboard includes a first adhesive portion 310, a first outer panel 320, a second outer panel 330, a third outer panel 340 and a fourth outer panel 350 which are sequentially arranged along the left and right sides. The first outer panel 320, the second outer panel 330, the third outer panel 340 and the fourth outer panel 350 are all rectangular, and the first outer panel 320 and the third outer panel 340 are consistent in shape and size, and the second outer panel 330 and the fourth outer panel 350 are the same in shape and size. There is a first outer crease between the first adhesive portion 310 and the first outer panel 320, a second outer crease between the first outer panel 320 and the second outer panel 330, a third outer crease between the second outer panel 330 and the third outer panel 340, and a fourth outer crease between the third outer panel 340 and the fourth outer panel 350, and the first outer crease, the second outer crease, the third outer crease and the fourth outer crease are parallel. The first paperboard is folded according to the first outer crease, the second outer crease, the third outer crease and the fourth outer crease, and then the first adhesive portion 310 is connected to the fourth outer panel 350 by adhesive. The first paperboard can be folded into a cylindrical structure, and after being folded along the first outer panel 320, the second outer panel 330, the third outer panel 340 and the fourth outer panel 350, the upper, lower, left and right sides of the outer box 100 are formed. The cylindrical structure can still be compressed into a thin sheet for convenient transportation. A first limiting piece 311 extending to the left is integrally formed on the left edge of the first adhesive portion 310 . The first limiting piece 311 is also adhered to the fourth outer plate 350 . The first limiting piece 311 forms the first limiting structure 130 .

[0064] Further, a foldable fifth cover plate 421, a sixth cover plate 431, a seventh cover plate 441 and an eighth cover plate 451 may be sequentially arranged at the lower edges of the first outer plate 320, the second outer plate 330, the third outer plate 340 and the fourth outer plate 350. The fifth cover plate 421, the sixth cover plate 431, the seventh cover plate 441 and the eighth cover plate 451 may be cross-folded to form a fully enclosed structure.

[0065] The folding method of the outer box 100 is roughly the same, and the second paperboard includes a second adhesive portion 410, a first inner panel 420, a second inner panel 430, a third inner panel 440 and a fourth inner panel 450 arranged in sequence along the left and right sides, and the first inner panel 420, the second inner panel 430, the third inner panel 440 and the fourth inner panel 450 are all rectangular, and the first inner panel 420 and the third inner panel 440 are consistent in shape and size, and the second inner panel 430 and the fourth inner panel 450 are the same in shape and size. There is a first inner fold between the second adhesive portion 410 and the first inner panel 420, a second inner fold between the first inner panel 420 and the second inner panel 430, a third inner fold between the second inner panel 430 and the third inner panel 440, and a fourth inner fold between the third inner panel 440 and the fourth inner panel 450, and the first inner fold, the second inner fold, the third inner fold and the fourth inner fold are parallel. The second paperboard is folded along the first inner fold, the second inner fold, the third inner fold and the fourth inner fold, and then the second adhesive portion 410 is connected to the fourth inner panel 450 by adhesive, so that the second paperboard can be folded into a cylindrical structure. The first inner panel 420, the second inner panel 430, the third inner panel 440 and the fourth inner panel 450 are folded to form the upper, lower, left and right sides of the inner box 200. The second inner panel 430 is provided with the window; the second adhesive portion 410 is used to be attached to the fourth inner panel 450.

[0066] A second limiting piece 411 extending to the left is integrally formed on the left edge of the second adhesive portion 410 . The second limiting piece 411 is also adhered to the fourth inner plate 450 . The second limiting piece 411 forms the second limiting structure 240 .

[0067] Furthermore, a first cover plate 321 may be disposed on the upper edge of the first inner plate 420 , a first buckle tongue 322 may be disposed on the upper edge of the first cover plate 321 , and a first bottom cover 323 may be disposed on the lower edge of the first inner plate 420 .

[0068] The first shoulder plate 331 is disposed on the upper edge of the second inner plate 430 , and the second bottom cover 332 is disposed on the lower edge of the second inner plate 430 .

[0069] The third bottom cover 341 is disposed on the lower edge of the third inner plate 440 .

[0070] The second shoulder plate 351 is disposed on the upper edge of the fourth inner plate 450 , and the fourth bottom cover 352 is disposed on the lower edge of the fourth outer plate 350 .

[0071] There are folds between the first inner plate 420 and the first cover plate 321, between the first cover plate 321 and the first buckle tongue 322, between the second inner plate 430 and the first shoulder plate 331, between the second inner plate 430 and the second bottom cover 332, between the third inner plate 440 and the third bottom cover 341, between the fourth inner plate 450 and the second shoulder plate 351, and between the fourth inner plate 450 and the fourth bottom cover 352. After the second paperboard is folded into a cylindrical structure, the first shoulder plate 331 and the second shoulder plate 351 can be folded in half relative to each other, and then the first cover plate 321 is covered on the outside of the first shoulder plate 331 and the second shoulder plate 351, and then the first buckle tongue 322 is inserted into the gaps between the first shoulder plate 331 and the second shoulder plate 351 and the third inner plate 440 respectively. The first bottom cover 323, the second bottom cover 332, the third bottom cover 341, and the fourth bottom cover 352 can be cross-folded to form a fully enclosed structure.

[0072] The storage box further includes a limiting insert 600, and the limiting insert 600, the first limiting insert 311, and the second limiting insert 411 may all have the same thickness. When selling, a portion of the limiting insert 600 may be inserted between the first top surface 120 and the second top surface 220 to prevent the inner box 200 and the outer box 100 from moving in the vertical direction, thereby preventing the inner box 200 from being switched to the unlocked state and falling out.

[0073] Two notches 140 are symmetrically arranged on the left and right side walls of the outer box 100, and the notches 140 are connected to the opening. The notches 140 are used for the user to pinch the inner box 200 so that the inner box 200 can be completely stored in the outer box 100. If the notches 140 are not arranged, the inner box 200 can be arranged to be longer in the front-to-back direction, so that a part of the front end of the inner box 200 is exposed outside the opening of the outer box 100.

[0074] In the front-to-back direction, the number of the second limiting structures 240 is at least two, and two adjacent second limiting structures are arranged at intervals. When the inner box 200 is completely located inside the outer box 100, unlocking can be achieved by lifting the inner box 200. After the inner box 200 is pulled so that the second limiting structure 240 near the outside passes through the first limiting structure 130, the user can stop pulling the inner box 200 upwards. After the inner box 200 is lowered, the inner box 200 is pulled forward again, so that the second second limiting structure 240 abuts against the first limiting structure 130. At this time, the window 230 can be set to be exposed. The second second limiting structure 240 can prevent the inner box 200 from being completely pulled out.

[0075] The second top surface 220 is provided with a tear structure 800 that closes the window 230, and the tear structure 800 is connected to the second top surface 220 by cutting a tear line. In other words, the window 230 can be sealed, and the tear structure 800 is removed before taking the material for the first time to expose the window 230.

[0076] This storage box is divided into an outer box 100 and an inner box 200, and is designed to be detachable. The outer box 100 has a simple, sturdy structure and can be reused, and the inner box 200 can be sold separately as a replacement, which reduces the overall cost of the paper box. It is also more low-carbon and environmentally friendly, in line with the concept of green environmental protection.

[0077] The materials of the first paperboard and the second paperboard can be the same or different, such as E-flute or F-flute paperboard. The difference between L2 and L1 is roughly the thickness of the paper used.

[0078] The user can customize whether the child lock mode of the storage box needs to be activated. If there are no children at home, there is no need to activate the child lock structure, but the user also wants to access the products more conveniently. The outer box 100 can be turned upside down, the first limiting structure 130 inside the outer box 100 can be turned upward, and then the inner box 200 can be put in. At this time, the first limiting structure 130 of the outer box 100 appears on the inner side of the top, and the second limiting structure 240 of the inner box 200 is still on the outer side of the bottom. The limiting structures of the inner and outer boxes 100 do not contact each other, and the inner box 200 can be opened and closed smoothly at any time.

[0079] Example 2

[0080] like Fig.10 - Fig.13 As shown, the difference from Embodiment 1 is that, in this embodiment, the inner box 200 has a second limiting structure 240 and a third limiting structure 700, and the heights of the two are different.

[0081] Specifically, a third limiting structure 700 is disposed on the outer wall of the second bottom surface 210, and the third limiting structure 700 is thicker than the second limiting structure 240. In the up-down direction, the distance between the bottom surface of the third limiting structure 700 and the outer wall of the second top surface 220 is L3, and L3 is greater than L1. The third limiting structure 700 is located behind the second limiting structure 240. When the second limiting structure 240 is in an unlocked state, the third limiting structure 700 is used to stop with the first limiting structure 130 to prevent the inner box 200 from completely sliding out of the outer box 100. When the third limiting structure 700 abuts against the first limiting structure 130, the window 230 is at least partially exposed to the outside of the outer box 100.

[0082] When the material needs to be taken out, the user can first pull up the inner box 200 so that the second limiting structure 240 is higher than the first limiting structure 130, and then pull out the inner box 200. However, since L3 is greater than L1, the third limiting structure 700 will stop and limit with the first limiting structure 130 after the window hole is exposed, thereby preventing the inner box 200 from completely falling out.

[0083] At the same time, the storage box in this embodiment can be operated with one hand, that is, the materials can be taken out with only one hand. The specific operation is as follows:

[0084] The user holds the outer box 100 and flips the storage box, that is, the first top surface 120 is downward and the first bottom surface 110 is upward, and then tilts the storage box so that the opening is tilted downward. As the outer box 100 flips, under the action of gravity, the first inner box 200 moves downward, and the second limiting structure 240 is offset from the first limiting structure 130, losing the limiting function, and unlocking is achieved. Due to the inclined opening, the material is pressed on the front end surface of the inner box 200, and the inner box 200 is pushed outward (the storage box can be gently shaken, and under the centrifugal effect, the inner box 200 is more likely to escape from the opening). After the window 230 is exposed, the material falls from the window 230, and under the action of the third limiting structure 700, the inner box 200 will not leave the outer box 100.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
