Description

Technical Field

[0001] This utility model relates to the field of packaging boxes, and more specifically, to a press-type pull-out packaging box. Background Technology

[0002] In today's society, with the growing popularity of green and environmentally friendly concepts, products such as cardboard-packaged laundry detergent pods are increasingly favored by consumers and are gradually gaining prominence in the market. While traditional cardboard-packaged products meet basic packaging needs to a certain extent, they have revealed many inconveniences and potential risks in actual use.

[0003] On the one hand, ordinary cardboard boxes are seriously inadequate in protecting children's safety, lacking effective child lock mechanisms. Children can easily access and open the lid, posing a constant risk of accidental ingestion of the gel beads inside, thus posing a significant threat to children's health and lives. On the other hand, when using pull-out packaging boxes, the inner box can be opened without restriction, easily detaching completely. Re-aligning and reinstalling it after use is inconvenient and negatively impacts the user experience.

[0004] A storage box with a locking structure disclosed in the prior art includes an outer box and an inner box. The outer box is a hollow structure with an open end. A pressing part is provided on the end of a first surface of the outer box away from the open end. The first surface is one of the surfaces constituting the open end. The inner box is a drawer-type container that is adapted to the shape of the outer box. The inner box can be received into the outer box through the open end. A first spring is fixedly provided on the end of the inner box facing the first surface. When the inner box is completely received into the outer box, the first spring is engaged with the pressing part. A limiting member is provided on the inner surface of the first surface near the open end. The limiting member is formed by folding the extension of the first surface inward at the edge of the open end. It is used to block the first spring during the process of the inner box being pulled out of the outer box, preventing the inner box from completely detaching from the outer box.

[0005] The aforementioned technical solution incorporates a lock on the storage box to prevent children from opening it and also to prevent the inner box from completely detaching from the outer box. However, this structure also causes inconvenience for adults. To open the storage box, one hand must press down on the pressing part to disengage the first spring clip and hold it in place, while the other hand pulls the inner box. This means that the storage box must be placed on a table or other support platform when opening; otherwise, the user must hold the outer box with one hand, and that hand must also press down on the pressing part, which presents a certain level of operational difficulty. Utility Model Content

[0006] To overcome the problem of inconvenient opening of packaging boxes with locking structures in the prior art, this utility model provides a push-pull packaging box with a child lock function and a function to prevent the inner box from falling out of the outer box, and makes it easy for users to pull out the inner box.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a push-to-open pull-out packaging box, including an outer box and an inner box; the outer box has an open end and a closed end at its two ends along a first direction, and the inner box is inserted into the outer box from the open end; the top of the inner box is provided with an opening communicating with the inner cavity of the inner box, and the outer wall of the inner box is provided with a first limiting part and a second limiting part at its two ends along the first direction; the inner wall of the outer box is provided with a third limiting part near the open end; when the inner box is in a closed state, the first limiting part engages with the third limiting part; when the inner box is in an open state, the second limiting part engages with the third limiting part.

[0008] In the above technical solution, the inner box is inserted into the outer box. The inner cavity of the inner box is used to hold objects, and the objects in the inner cavity can be removed when the inner box is in the open state. The inner box being in the open state means pulling it out of the outer box, while the inner box being in the closed state means it is inside the outer box. When the inner box is in the closed state, and the user wants to pull it out, they only need to press the first limiting part with one hand, causing the first limiting part or the inner box to deform, thus disengaging the first limiting part and the third limiting part, allowing the inner box to be pulled out smoothly, achieving simple one-handed operation. If the outer box moves along with the inner box when it is pulled out, the operator only needs to hold the outer box with their other hand, posing no operational difficulty.

[0009] When the inner box is pulled out to a certain distance and the opening is exposed, the inner box cannot be pulled out further because the second limiting part is engaged with the third limiting part, thus preventing the inner box from completely detaching from the outer box.

[0010] The first, second, and third limiting parts can all take various forms. For example, the first and third limiting parts can be interlocking protrusions and grooves, respectively. If the third limiting part is a protrusion, the second limiting part can also be a protrusion, or it can be a groove that slides along the protrusion and is restricted at its end. If the third limiting part is a groove, the second limiting part can be a protrusion that fits into the third limiting part. The protrusions mentioned in the first and second limiting parts can be movable springs connected to the inner box at one end, plate-shaped, columnar, or three-dimensional protrusions that fit against the wall of the inner box, or other components that can increase the thickness of the wall at a certain point of the inner box.

[0011] Furthermore, the first limiting part is a protrusion provided on the outer wall of the inner box, the third limiting part is a protrusion provided on the inner wall of the outer box; and the second limiting part is a protrusion provided on the outer wall of the inner box.

[0012] Furthermore, the second limiting part is a movable spring, which is formed by not completely cutting the outer wall of the inner box.

[0013] Furthermore, the inner box is provided with a cutting line at the first limiting part. When the first limiting part is pressed, the cutting line allows the first limiting part to deform more effectively toward the center of the inner box, thereby disengaging from the third limiting part and reducing the deformation of the entire inner box. At the same time, the cutting line also has an elastic force to allow the first limiting part to return to its original position.

[0014] Furthermore, the thickness of the first limiting part is less than or equal to the wall thickness of the inner box; the thickness of the third limiting part is less than or equal to the wall thickness of the outer box. The greater the thickness of the first and third limiting parts, the stronger the engagement between them. However, this requires greater deformation of the first limiting part or the inner box to separate the first limiting part from the third limiting part and pull out the inner box. To balance the two, the thickness of the first limiting part should not exceed the wall thickness of the inner box, and the thickness of the third limiting part should not exceed the wall thickness of the outer box.

[0015] Furthermore, both the first and second limiting parts are located on the wall surface adjacent to the opening. The first and third limiting parts can be located on any wall surface of the inner box except for the two ends in the first direction. Being located on the wall surface adjacent to the opening means that the first limiting part can be pressed from the side, facilitating user operation. Simultaneously, this avoids the situation where, when both the first limiting part and the opening are located on the top surface of the inner box, the presence of the opening on the top surface results in insufficient strength, making repeated pressing prone to damage and lacking sufficient elasticity to allow the first limiting part to spring back to its original position.

[0016] Furthermore, both ends of the inner box in the first direction are located inside the outer box. The outer box has a first cutout portion for exposing the first limiting portion, and a second cutout portion for exposing at least a portion of the inner box is provided on the side of the outer box opposite the first cutout portion. The entire inner box is located inside the outer box, resulting in a more aesthetically pleasing design. Additionally, the inner box can be pulled out by holding the portion of the inner box exposed from the first and second cutout portions and simultaneously pressing the first limiting portion.

[0017] Furthermore, the first hollow portion is elongated, and the second hollow portion has a different shape from the first hollow portion. The thumb is the part of the hand that is easiest to exert force on. Setting the first hollow portion to be elongated can just accommodate the thumb, allowing the thumb to exert force at the most suitable position of the first limiting portion, thus making it easier for the first limiting portion to separate from the third limiting portion. At the same time, this shape can also serve to distinguish the two parts for the user.

[0018] Furthermore, the second cutout portion is fan-shaped, semi-circular, polygonal, or irregular in shape; the area of ​​the second cutout portion is larger than the area of ​​the first cutout portion. The second cutout portion can be of any shape, and having a larger area is only necessary to accommodate multiple fingers touching the inner box, thereby facilitating the gripping of the inner box and the application of force with the thumb.

[0019] Furthermore, the inner box has a cover portion at the opening to close the opening, and an easy-tear line is provided between the cover portion and the inner box. The cover portion can seal the object inside the cavity of the inner box, making it convenient for the inner box to be sold as a separate replacement pack, while the easy-tear line allows the cover portion to be torn off quickly and accurately.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the snap-fit ​​of the first limiting part and the third limiting part gives the packaging box a child lock function, and the second limiting part and the third limiting part prevent the inner box from easily detaching from the outer box. With these two locking functions, the user only needs to press the first limiting part when holding the inner box with one hand to disengage the first limiting part from the third limiting part, and then pull it outward to pull out the inner box. The operation is simpler and has no operational difficulty. Attached Figure Description

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0032] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0033] Example 1

[0034] like Figure 1-5 The illustration shows an embodiment 1 of a push-to-open pull-out packaging box, comprising an outer box 100 and an inner box 200. The outer box 100 has an open end and a closed end at its two ends along a first direction, and the inner box 200 is inserted into the outer box 100 from the open end. The top of the inner box 200 has an opening 210 communicating with the inner cavity of the inner box 200. The outer wall of the inner box 200 has a first limiting portion 220 and a second limiting portion 230 at its two ends along the first direction. The inner wall of the outer box 100 has a third limiting portion 110 near the open end. When the inner box 200 is in a closed state, the first limiting portion 220 engages with the third limiting portion 110; when the inner box 200 is in an open state, the second limiting portion 230 engages with the third limiting portion 110. The first direction is the length direction of the inner box 200 and the outer box 100, and is also the direction of sliding movement of the inner box 200 relative to the outer box 100.

[0035] Specifically, the first limiting part 220 is a protrusion on the outer wall of the inner box 200, and the third limiting part 110 is a protrusion on the inner wall of the outer box 100; the second limiting part 230 is a movable spring on the outer wall of the inner box 200, which is formed by not completely cutting the outer wall of the inner box 200. Both the protrusions and the glued joints are formed simultaneously during the manufacturing process at the cardboard box factory, ensuring structural stability and consistency.

[0036] In this embodiment, as Figure 2 As shown, the inner box 200 has a cutting line portion 240 at the first limiting portion 220. In this embodiment, the cutting line portion 240 is provided along the outer contour of the mating end of the first limiting portion 220 and the third limiting portion 110. When the first limiting portion 220 is pressed, the cutting line portion 240 can better deform towards the center of the inner box 200, thereby disengaging from the third limiting portion 110, reducing the deformation of the entire inner box 200. At the same time, the cutting line portion 240 also has an elastic force to allow the first limiting portion 220 to return to its original position.

[0037] In this embodiment, both the first limiting part 220 and the second limiting part 230 are located on the wall surface adjacent to the opening 210. The first limiting part 220 and the second limiting part 230 can be located on any wall surface of the inner box 200 except for the wall surfaces at both ends in the first direction. Being located on the wall surface adjacent to the opening 210 means that the first limiting part 220 can be pressed from the side, which is convenient for the user to operate.

[0038] Specifically, both ends of the inner box 200 in the first direction are located inside the outer box 100, such as... Figure 4 and 5 As shown, the outer box 100 has a first cutout portion 120 for exposing the first limiting portion 220, and a second cutout portion 130 for exposing at least a portion of the inner box 200 is provided on the side opposite to the first cutout portion 120. The first cutout portion 120 is elongated, and in this embodiment, elongation refers to a shape whose length is greater than its width along the first direction, and it can be rectangular or have curves or arcs. The second cutout portion 130 is fan-shaped, semi-circular, polygonal, or irregular; in this embodiment, it is semi-circular. The function of the first cutout portion 120 and the second cutout portion 130 is that when the inner box 200 is completely inside the outer box 100, the inner box 200 can be directly held through the first cutout portion 120 and the second cutout portion 130. The first hollow portion 120 is elongated to accommodate a thumb, allowing the thumb to be positioned optimally at the first limiting portion 220, thus facilitating separation of the first limiting portion 220 from the third limiting portion 110. The second hollow portion 130 has a larger area, allowing multiple fingers to contact the inner box 200, thus facilitating gripping of the inner box 200 and thumb exertion. The difference in shape and area between the first and second hollow portions serves to differentiate them for the user.

[0039] In addition, in this embodiment, when the inner box 200 is in an open state, the second limiting part 230 is at least partially located at the first hollow part 120.

[0040] The working principle or workflow of this embodiment is as follows: The inner box 200 is inserted into the outer box 100. The inner cavity of the inner box 200 is used to hold objects, and the objects in the inner cavity can be removed when the inner box 200 is in the open state. For example... Figure 7 As shown, the inner box 200 being in the open state means that the inner box 200 is pulled out from the outer box 100, as... Figure 6 As shown, the inner box 200 being in a closed state means that the inner box 200 is located inside the outer box 100. When the inner box 200 is in a closed state, and the user wants to pull out the inner box 200, they only need to place their thumb on the first limiting part 220 exposed from the first cutout 120, and place at least two other fingers on the wall of the inner box 200 exposed from the second cutout 130. After gripping the inner box 200, the thumb applies force to press the first limiting part 220, causing the first limiting part 220 to compress and deform the inner box 200, causing the first limiting part 220 and the third limiting part 110 to separate, and then pull the inner box 200 out from the outer box 100, achieving a simple one-handed operation. If the outer box 100 moves along with the inner box 200 when it is pulled out, the operator only needs to hold the outer box 100 with their other hand, which is not difficult to operate.

[0041] When the inner box 200 is pulled out a certain distance and the opening 210 is exposed, it is in an open state. Because the second limiting part 230 and the third limiting part 110 are engaged, the inner box 200 cannot be pulled out further, thus preventing the inner box 200 from completely detaching from the outer box 100. If you want the inner box 200 to completely detach from the outer box 100 at this time, you can press the second limiting part 230 located at the first hollow part 120. Since the second limiting part 230 in this embodiment is a movable spring, you only need to press the movable spring to allow the inner box 200 to continue to move outward, allowing the entire inner box 200 to detach from the outer box 100.

[0042] The beneficial effects of this embodiment are as follows: the engagement of the first limiting part 220 and the third limiting part 110 gives the packaging box a child lock function; the second limiting part 230 and the third limiting part 110 prevent the inner box from easily detaching from the outer box 100. With these two locking functions, the user only needs to press the first limiting part 220 while holding the inner box 200 with one hand to disengage the first limiting part 220 from the third limiting part 110, and then pull it outwards to pull out the inner box 200. The operation is simpler and has no operational difficulty.

[0043] Other implementations of the first limiting part 220, the second limiting part 230, and the third limiting part 110 are also provided. Both the first limiting part 220 and the second limiting part 230 are protrusions, and the third limiting part 110 is a groove extending from the open end to the closed end. Both the first limiting part 220 and the second limiting part 230 extend into the groove to form a limit, thereby pressing the first limiting part 220 and the second limiting part 230 out of the groove, allowing the inner box 200 to move relative to the outer box 100. Alternatively, the first limiting part 220 and the second limiting part 230 can be grooves, while the third limiting part 110 is a protrusion, with the same principle. However, due to the low convenience of processing grooves on the cardboard box and the impact on strength, its practicality is poor.

[0044] Another embodiment of the inner and outer boxes is provided, wherein the inner box portion is located outside the outer box, and a portion of the first limiting portion 220 is also located outside the outer box to facilitate pressing by the user.

[0045] Example 2

[0046] A second embodiment of a push-to-open pull-out packaging box differs from embodiment 1 in that the thickness of the first limiting part 220 is less than or equal to the wall thickness of the inner box 200; and the thickness of the third limiting part 110 is less than or equal to the wall thickness of the outer box 100. The greater the thickness of the first limiting part 220 and the third limiting part 110, the stronger the interlocking force. This requires greater deformation of either the first limiting part 220 or the inner box 200 to separate the first limiting part 220 from the third limiting part 110 and pull out the inner box 200. To balance these two aspects, the first limiting part 220 should not exceed the wall thickness of the inner box 200, and the thickness of the third limiting part 110 should not exceed the wall thickness of the outer box 100. In this embodiment, the packaging box is folded from a single sheet of paper; therefore, the thickness of the first limiting part 220 is equal to the wall thickness of the inner box 200, and the thickness of the third limiting part 110 is equal to the wall thickness of the outer box 100.

[0047] The remaining working principles and features of this embodiment are the same as those of Embodiment 1.

[0048] Example 3

[0049] A third embodiment of a push-to-open pull-out packaging box, based on embodiment 1 or 2, differs from embodiment 1 or 2 in that, as... Figure 3 As shown, the inner box 200 has a cover portion 250 at the opening 210 to close the opening 210, and an easy-tear line is provided between the cover portion 250 and the inner box 200. The cover portion 250 can seal the object inside the cavity of the inner box 200, making it convenient for the inner box 200 to be sold as a separate replacement pack, and the easy-tear line allows the cover portion 250 to be torn off quickly and accurately.

[0050] The remaining working principles and features of this embodiment are the same as those of Embodiment 1 or Embodiment 2.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
