Description

Technical Field

[0001] The utility model relates to the technical field of daily chemical product packaging, in particular to a storage box. Background Art

[0002] As consumers increasingly embrace green and environmentally friendly concepts, laundry detergent beads and dishwashing tablets packaged in paper boxes are increasingly appearing on the market. However, current paper boxes lack latches or childproof locks, making it easy for children to open the lids, potentially exposing them to the risk of accidental ingestion and injury. Utility Model Content

[0003] The purpose of the utility model is to provide a storage box to alleviate the technical problem that the existing storage boxes do not have a child lock function.

[0004] The utility model provides a storage box, comprising:

[0005] An outer box, wherein the front end surface of the outer box has an opening communicating with the inside and outside, the outer box includes a first bottom surface and a first top surface, a first limiting structure is provided on the inner wall of the first bottom surface, and a distance L1 is defined between the top surface of the first limiting structure and the inner wall of the first top surface in the vertical direction;

[0006] An inner box, the inner box comprising a second bottom surface and a second top surface, the second top surface being provided with a window communicating with the inside and outside; a second limiting structure being provided on an outer wall of the second bottom surface, wherein a distance L2 between a bottom surface of the second limiting structure and an outer wall of the second top surface in a vertical direction is less than or equal to L1, so that the inner box can vertically move relative to the outer box between a locked state and an unlocked state;

[0007] 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 relative to the outer box;

[0008] 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.

[0009] Furthermore, the outer box is formed by folding and pasting the first paperboard.

[0010] Furthermore, the first paperboard includes a first adhesive portion, a first outer panel, a second outer panel, a third outer panel, and a fourth outer panel arranged in sequence along the left and right sides, a first outer fold is defined between the first adhesive portion and the first outer panel, a second outer fold is defined between the first outer panel and the second outer panel, a third outer fold is defined between the second outer panel and the third outer panel, and a fourth outer fold is defined between the third outer panel and the fourth outer panel, and the first outer fold, the second outer fold, the third outer fold, and the fourth outer fold are parallel to each other;

[0011] The first outer panel, the second outer panel, the third outer panel and the fourth outer panel are folded to form the upper, lower, left and right sides of the outer box; the first adhesive portion is used to adhere to the fourth outer panel;

[0012] A first limiting piece extending toward the left is integrally formed on the left edge of the first adhesive portion, and the first limiting piece forms the first limiting structure.

[0013] Furthermore, the inner box is formed by folding and pasting the second paperboard.

[0014] Furthermore, the second paperboard includes a second adhesive portion, a first inner panel, a second inner panel, a third inner panel, and a fourth inner panel arranged in sequence along the left and right sides, a first inner fold is formed between the second adhesive portion and the first inner panel, a second inner fold is formed between the first inner panel and the second inner panel, a third inner fold is formed between the second inner panel and the third inner panel, and a fourth inner fold is formed between the third inner panel and the fourth inner panel, and the first inner fold, the second inner fold, the third inner fold, and the fourth inner fold are parallel to each other;

[0015] The first inner panel, the second inner panel, the third inner panel and the fourth inner panel are folded to form the upper, lower, left and right sides of the inner box; the second inner panel is provided with the window; the second adhesive portion is used to be attached to the fourth inner panel;

[0016] A second limiting piece extending toward the left is integrally formed on the left edge of the second adhesive portion, and the second limiting piece forms the second limiting structure.

[0017] Furthermore, the storage box further includes a limiting insert, a portion of which is inserted between the first top surface and the second top surface to prevent the inner box and the outer box from moving in the up and down directions.

[0018] Furthermore, two notches are symmetrically provided on the left and right side walls of the outer box, the notches are communicated with the opening, and the notches are used for the user to pinch the inner box.

[0021] Furthermore, a third limiting structure is provided on the outer wall of the second bottom surface. In the vertical direction, the distance between the bottom surface of the third limiting structure and the outer wall of the second top surface is L3, and L3 is greater than L1.

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

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

[0024] The utility model has at least the following advantages or beneficial effects:

[0025] The storage box provided by the utility model comprises: an outer box and an inner box, the front end surface of the outer box having an opening communicating with the inside and the outside, the outer box comprising a first bottom surface and a first top surface, the inner wall of the first bottom surface being provided with a first limiting structure, and in the vertical 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 comprising a second bottom surface and a second top surface, the second top surface being provided with a window communicating with the inside and the outside; a second limiting structure being provided on the outer wall of the second bottom surface, and in the vertical 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 relative to the outer box to a locked state and an unlocked state; 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 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] During use, the inner box is located inside the outer box and can hold materials. The first top surface prevents the materials from escaping through the window. To access the materials, the user holds the outer box with their right hand and the inner box with their left hand, then pulls the inner box upward to unlock it. Pulling the inner box forward allows the inner box to be pulled out of the outer box, exposing the window. Without pulling the inner box upward, the inner box is locked, with the first retaining structure blocking the second retaining structure, preventing it from being pulled out. Therefore, removing the inner box requires a special opening procedure to prevent children from accidentally opening the storage box and ingesting the contents. Furthermore, when the outer box is not in use (i.e., when the child lock is not required), the user can flip the outer box upside down. When combined with the inner box, the first and second retaining structures are staggered, one above and one below. This creates an unrestricted position, allowing the inner box to be opened freely without the child lock. This allows the user to flexibly switch between usage modes.

[0047] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0048] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0049] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0050] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is typically placed when in use. These terms are intended solely to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation.

[0051] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0052] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0053] like Figure 1 - Figure 9 As shown, the storage box provided by the present invention can be used to hold laundry beads.

[0054] like Figure 1 - Figure 3 As shown, the storage box includes an outer box 100 and an inner box 200, wherein the inner box 200 is placed in the outer box 100. The inner box 200 and the outer box 100 are both roughly rectangular.

[0055] like Figure 2 As shown, the front end 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.

[0056] A first limiting structure 130 is provided on the inner wall of the first bottom surface 110. The first limiting structure 130 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.

[0057] 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 usage, the second bottom surface 210 faces downward and the second top surface 220 faces upward. A window 230 connecting the inside and the outside is provided on the second top surface 220 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 - Figure 9 shown.

[0058] like Figure 7 As shown, in the locked state, that is, 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.

[0059] like Figure 8 and Figure 9As shown, in the unlocked state, the user needs to manually adjust the inner box 200 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. The first limiting structure 130 no longer stops the second limiting structure 240, allowing the second limiting structure 240 to pass over the first limiting structure 130 and exit from the opening.

[0060] During use, the inner box 200 is located inside the outer box 100. Materials can be stored in the inner box 200, and the materials cannot escape through the window 230 due to the obstruction of the first top surface 120. When the user needs to access the materials, they can hold the outer box 100 with their right hand and the inner box 200 with their left hand, then pull the inner box 200 upward to switch the inner box 200 to the unlocked state. Pulling the inner box 200 forward allows the inner box 200 to be pulled out of the outer box 100, exposing the window 230. Without pulling the inner box 200 upward, the inner box 200 is locked, and the first limiting structure 130 blocks the second limiting structure 240, preventing the inner box 200 from being pulled out. Therefore, removing the inner box 200 requires a special opening procedure to prevent children from accidentally opening the storage box and ingesting the materials inside.

[0061] like Figure 5 As shown, to reduce the transportation cost of the storage box, the outer box 100 can be formed by folding and gluing a first cardboard sheet. Similarly, the inner box 200 is formed by folding and gluing a second cardboard sheet. The first and second cardboard sheets are planar. After gluing the inner box 200 and outer box 100 together, they can still be folded flat, saving transportation costs. After being shipped to the condensation bead factory, they only need to be manually folded to form a three-dimensional box structure, without any equipment investment.

[0062] 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 arranged in sequence 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 fold between the first adhesive portion 310 and the first outer panel 320, a second outer fold between the first outer panel 320 and the second outer panel 330, a third outer fold between the second outer panel 330 and the third outer panel 340, and a fourth outer fold between the third outer panel 340 and the fourth outer panel 350, and the first outer fold, the second outer fold, the third outer fold and the fourth outer fold are parallel. The first paperboard is folded according to the first outer fold, the second outer fold, the third outer fold and the fourth outer fold, 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 folding along the first outer panel 320, the second outer panel 330, the third outer panel 340 and the fourth outer panel 350, it forms the upper, lower, left and right sides of the outer box 100. The cylindrical structure can still be compressed into a thin sheet for easy 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 .

[0063] Furthermore, a foldable fifth cover plate 421, sixth cover plate 431, seventh cover plate 441, and eighth cover plate 451 may be sequentially provided at the lower edges of the first outer panel 320, the second outer panel 330, the third outer panel 340, and the fourth outer panel 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.

[0064] The folding method of the outer box 100 is roughly the same. 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, which are arranged in sequence along the left and right sides. The first inner panel 420, the second inner panel 430, the third inner panel 440, and the fourth inner panel 450 are all rectangular. In addition, 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. 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, second, third, and fourth inner folds, and then the second adhesive portion 410 is connected to the fourth inner panel 450 using adhesive to form a cylindrical structure. The first, second, third, and fourth inner panels 420, 430, 440, and 450, when folded, form the top, bottom, 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 adhere to the fourth inner panel 450.

[0065] 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 .

[0066] Furthermore, a first cover plate 321 may be provided on the upper edge of the first inner plate 420 , a first buckle tongue 322 may be provided on the upper edge of the first cover plate 321 , and a first bottom cover 323 may be provided on the lower edge of the first inner plate 420 .

[0067] 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 .

[0068] The third bottom cover 341 is disposed on the lower edge of the third inner plate 440 .

[0069] A second shoulder plate 351 is provided on the upper edge of the fourth inner plate 450 , and a fourth bottom cover 352 is provided on the lower edge of the fourth outer plate 350 .

[0070] Creases are located between the first inner panel 420 and the first cover panel 321, between the first cover panel 321 and the first buckle 322, between the second inner panel 430 and the first shoulder panel 331, between the second inner panel 430 and the second bottom cover 332, between the third inner panel 440 and the third bottom cover 341, between the fourth inner panel 450 and the second shoulder panel 351, and between the fourth inner panel 450 and the fourth bottom cover 352. After the second paperboard is folded into a cylindrical structure, the first and second shoulder panels 331 and 351 can be folded in half. The first cover panel 321 can then be placed over the outsides of the first and second shoulder panels 331 and 351. The first buckle 322 can then be inserted into the gaps between the first and second shoulder panels 331 and 351, respectively, and the third inner panel 440. 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.

[0071] The storage box also includes a retaining plate 600. The retaining plate 600, the first retaining plate 311, and the second retaining plate 411 can all have the same thickness. During sales, a portion of the retaining plate 600 can 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 vertically, thereby preventing the inner box 200 from being released when the inner box 200 is unlocked.

[0072] Two notches 140 are symmetrically provided on the left and right side walls of the outer box 100. The notches 140 communicate with the opening and allow a user to grasp the inner box 200 so that the inner box 200 can be completely accommodated within the outer box 100. If the notches 140 are not provided, the inner box 200 can be made longer in the front-to-back direction, so that a portion of the front end of the inner box 200 is exposed outside the opening of the outer box 100.

[0073] There are at least two second limiting structures 240 in the front-to-back direction, and two adjacent second limiting structures 240 are spaced apart. When the inner box 200 is completely inside the outer box 100, it can be unlocked by lifting the inner box 200. After the inner box 200 is pulled so that the second limiting structure 240 near the outside passes the first limiting structure 130, the user can stop pulling the inner box 200 upward. After the inner box 200 is lowered, the inner box 200 can be pulled forward again, causing the second second limiting structure 240 to abut against the first limiting structure 130. At this point, the window 230 can be exposed. The second second limiting structure 240 prevents the inner box 200 from being completely pulled out.

[0074] The second top surface 220 is provided with a tear structure 800 that seals the window 230. 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 the first use of the material to expose the window 230.

[0075] 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 is reusable, and the inner box 200 can be sold separately as a replacement, reducing 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.

[0076] The first paperboard and the second paperboard can be made of the same material or different materials, such as E-flute or F-flute paperboard. The difference between L2 and L1 is roughly the thickness of the paper used.

[0077] The user can customize whether to activate the child lock mode of this storage box. If there are no children at home and there is no need to activate the child lock structure, but the user still wants to have more convenient access to the products, the outer box 100 can be flipped upside down, the first limiting structure 130 inside the outer box 100 is turned upward, and then the inner box 200 is placed inside. At this point, 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 remains on the outer side of the bottom. The limiting structures of the inner and outer boxes 100 do not touch each other, and the inner box 200 can be opened and closed smoothly at any time.

[0078] Example 2

[0079] like Figure 10 - Figure 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.

[0080] Specifically, a third limiting structure 700 is disposed on the outer wall of the second bottom surface 210. The third limiting structure 700 is thicker than the second limiting structure 240. In the vertical 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 unlocked, the third limiting structure 700 is used to stop 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 the first limiting structure 130, the window 230 is at least partially exposed outside the outer box 100.

[0081] When materials need to be taken out, the user can first pull the inner box 200 upwards, so that the second limiting structure 240 is higher than the first limiting structure 130, and then pull the inner box 200 outwards. 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.

[0082] 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:

[0083] 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 its limiting function, and unlocking is achieved. Due to the tilted opening, the material is pressed against the front surface of the inner box 200, pushing the inner box 200 outward (the storage box can be gently shaken, and under the action of centrifugation, the inner box 200 is more easily removed from the opening). After the window 230 is exposed, the material falls through the window 230, and the inner box 200 will not leave the outer box 100 due to the action of the third limiting structure 700.
