Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, specifically to a side-opening packaging box. Background Technology

[0002] Existing packaging boxes, such as traditional cigarette boxes, mostly open with a top-flip lid. This opening method is monotonous, and each box typically only contains one type of item, limiting its usability. While some improved side-opening packaging box designs exist, such as opening by lifting the inner box from the bottom, these designs often suffer from inconvenient opening, inaccurate positioning, and the inner box easily falling off. For example, the side-opening packaging box disclosed in prior art CN 212373967 U uses an opening hole at the bottom of the outer box to lift the inner box. While novel, its positioning structure relies on the cooperation of a positioning clip and a positioning clip slot, resulting in unsatisfactory positioning in both open and closed states, and the inner box may accidentally open due to shaking. Furthermore, the complex inner box structure of existing packaging boxes makes it inconvenient to handle strip-shaped items. Therefore, it is necessary to design a new type of side-opening packaging box to solve the aforementioned technical problems. Utility Model Content

[0003] The purpose of this invention is to provide a side-opening packaging box with a reasonable structure and reliable positioning.

[0004] A side-opening packaging box includes an outer box and an inner box for use with the outer box. The outer box has an outer box receiving cavity, which houses the inner box. One side of the outer box has an opening for the inner box to be flipped open on one side. The inner box includes a perimeter composed of several connecting edges, within which the inner box receiving cavity is located, and an opening is provided at the top. A limiting structure is provided at the top inner side of the outer box, and the opening end of the inner box has a limiting ear 1 and a limiting ear 2. When the inner box is rotated open, the limiting ear 1 moves into the limiting structure and engages. When the inner box is closed, the limiting ear 2 abuts against the top of the outer box to achieve a limiting effect.

[0005] The single-sided flip-opening structure makes opening the packaging box more convenient, while the double-limiting design ensures stability during use.

[0006] Preferably, the inner box includes a first connecting edge connected to the outer box, a second connecting edge disposed on the opposite side of the first connecting edge, and two third connecting edges between the two ends of the first and second connecting edges, with the end face of the third connecting edge near the opening being an arc-shaped connecting surface.

[0007] The curved connecting surface design makes the inner box flip more smoothly and reduces frictional resistance.

[0008] Preferably, the first connecting edge and the second connecting edge are arranged in parallel, and the length of the first connecting edge is much shorter than the length of the second connecting edge.

[0009] The asymmetrical connecting edge design allows the inner box to tilt at the optimal angle when opened, making it easy to put in and take out items.

[0010] Preferably, the first connecting edge is provided with a limiting ear one at the end near the opening, and the second connecting edge is provided with a limiting ear two at the end near the opening.

[0011] The placement of the limiting ears should be arranged reasonably to ensure the optimal limiting effect.

[0012] Preferably, the limiting structure is U-shaped, including a mounting part, an abutment part, and a limiting slot disposed between the two. The mounting part is fixedly connected to the inner wall of the top of the outer box, and the abutment part is inclined from the side away from the mounting part to the side of the limiting slot to form an inclined surface, so that the end of the abutment part near the side of the limiting slot can abut and limit the second limiting ear during the process of flipping and opening the inner box.

[0013] The U-shaped limiting structure provides multiple limiting functions to ensure precise positioning of the inner box in both open and closed states.

[0014] Preferably, the outer box, on the side opposite the inner box, has a flip-open side cover. The side cover has a slot away from the connecting side, and the outer box side wall has a buckle. The outer box can be closed and opened by the cooperation of the buckle and the slot. Beneficial effect: The design of the side cover and buckle enhances the sealing of the packaging box, effectively preventing dust and moisture.

[0015] Preferably, the inner box is surrounded by a flexible material, and the outer box cavity is connected to the bottom of the inner box cavity.

[0016] Flexible materials reduce damage when handling items, and the bottom open design enhances ease of use.

[0017] Preferably, the opening is located on a single side of the outer box, allowing for single-sided flip-opening.

[0018] The single-sided opening method makes operation simpler and more intuitive, improving the user experience.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) Reliable limiting: By using the U-shaped limiting structure set on the top of the outer box and the double limiting ears on the inner box, precise limiting is achieved in the open and closed states respectively, effectively preventing the inner box from being accidentally opened or falling off, and the stability of use is high; (2) Smooth opening: The arc-shaped surface design of the inner box connecting edge and the guiding slope on the limiting structure together ensure the smoothness of the inner box flipping process, making operation labor-saving and convenient. (3) Optimized structure: The inner box adopts an asymmetrical connecting edge design, so that it presents the best tilt angle after opening, which is convenient for picking up and putting down items; at the same time, the added side cover and buckle structure further improve the sealing and integrity of the packaging box.

Detailed Implementation

[0026] The technical solutions in the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Those skilled in the art can obtain other embodiments in conjunction with the embodiments of this utility model without creative effort, and these other embodiments are also within the protection scope of this utility model.

[0027] Example 1 See Figures 1 to 5 This embodiment provides a basic implementation method for a side-opening packaging box.

[0028] The side-opening packaging box mainly includes an outer box 100 and an inner box 200 that can be flipped and housed within the outer box 100. The outer box 100 is typically a rectangular box made of rigid cardboard or plastic, with an outer box receiving cavity 110 formed inside. One side wall of the outer box 100 (with...) Figure 1 An opening 111 is provided on the left side wall (as shown in the direction indicated), the size of which allows the inner box 200 to be flipped outward and extended.

[0029] The inner box 200 is movably disposed within the outer box cavity 110, and is enclosed by a perimeter 240, with an opening 211 at the top for taking out and placing items. Specifically, the inner box 200 includes a first connecting edge 201 that is hinged to or flexibly connected to the outer box 100 (e.g., in the bottom area near the opening 111), a second connecting edge 202 opposite to the first connecting edge 201, and two third connecting edges 203 connecting the ends of the first and second connecting edges 201 and 202. Preferably, the length of the first connecting edge 201 is significantly shorter than the length of the second connecting edge 202, so that the inner box 200 can form an angle that facilitates taking out items after opening. The upper end of the third connecting edge 203 near the opening 211 is provided with an arc-shaped connecting surface 204, which ensures a smooth transition of contact between the inner box 200 and the inner wall of the outer box 100 during the flipping process, reducing friction and jamming.

[0030] To achieve reliable positioning, a positioning structure 300 is fixedly provided on the top of the inner side of the outer box 100. This positioning structure 300 can be a separate component fixed by adhesive or snap-fit, or it can be an integrally formed structure on the top of the outer box 100. In this embodiment, the positioning structure 300 is preferably U-shaped, including a mounting portion 301 fixed to the inner wall of the top of the outer box 100, an abutment portion 302 opposite to and spaced apart from the mounting portion 301, and a positioning groove 303 formed between the mounting portion 301 and the abutment portion 302. An inclined surface 305 is formed on the side of the abutment portion 302 facing the positioning groove 303.

[0031] Correspondingly, at the opening end of the inner box 200, a limiting ear 310 is provided at the upper end of the first connecting edge 201, and a limiting ear 320 is provided at the upper end of the second connecting edge 202. The limiting ear 310 and the limiting ear 320 can be protrusions integrally formed with the edge of the inner box 200, or they can be independent components added later.

[0032] The working principle of this embodiment is as follows: Closed state: The inner box 200 is completely contained within the outer box cavity 110. At this time, the limiting ear 320 abuts against the inner top wall of the outer box 100 under its own weight or a slight external force, thereby restricting the inner box 200 from moving further toward the opening 111 and maintaining a stable closure.

[0033] Opening process: The user presses the area near the second connecting edge 202 of the inner box 200 from the outside with their finger, causing the inner box 200 to flip outward around the base of the first connecting edge 201. During this process, the second limiting ear 320 slides along the inclined surface 305 of the limiting structure 300, receiving guidance and initial limiting. Simultaneously, the first limiting ear 310 moves towards the limiting slot 303 as the inner box 200 rotates.

[0034] Fully open (see appendix) Figure 1 To be continued Figure 3 When the inner box 200 is flipped to a certain angle (for example, the maximum opening angle is limited by the limiting structure 300 or the outer box 100 structure), the limiting ear 310 slides into and engages with the limiting slot 303. At this time, the engagement between the limiting ear 310 and the limiting slot 303 provides the main holding force in the open state, preventing the inner box 200 from accidentally falling back. The inner box 200 is tilted due to the shorter first connecting edge 201, making it easier to put in and take out items.

[0035] To further enhance the sealing of the outer box 100, a side cover (with) can be connected to the side wall (left side wall) of the outer box 100 opposite to the opening 111 via a flip-up connection (such as an indentation line or a hinge). Figure 3 The free end of the side cover is provided with a slot 410, and a corresponding elastically deformable buckle 400 is provided on the side wall of the outer box 100. When the side cover is closed, the buckle 400 engages with the slot 410 to lock it in place.

[0036] Example 2 The main difference between this embodiment and Embodiment 1 lies in the material of the inner box 200 and its connection method with the outer box 100.

[0037] In this embodiment, the perimeter 240 of the inner box 200 is made of a flexible material, such as soft plastic, silicone, or special composite paper with a certain degree of elasticity and toughness. This design allows the inner box 200 to undergo slight deformation when squeezed, which on the one hand better adapts to and protects the contents, reducing bumps and damage during handling; on the other hand, its flexibility also makes the flipping and opening process smoother, which helps the limiting ears cooperate with the limiting structure.

[0038] Furthermore, the bottom of the outer box cavity 110 is connected to the bottom of the inner box cavity 210 of the inner box 200. This bottom connection design facilitates air circulation inside the packaging box, which is beneficial for items that require moisture dissipation and heat dissipation (such as certain foods and electronic products); at the same time, it is also easy to clean, as any debris that falls in can be cleaned up from the bottom connection.

[0039] Example 3 The main difference between this embodiment and Embodiment 1 lies in the way the limiting structure 300 and the limiting ear work together.

[0040] In this embodiment, the limiting structure 300 is not an independent "U"-shaped component, but rather a recessed latch formed directly by stamping or molding from the inner top wall of the outer box 100. The shape of the first limiting ear 310 can be adjusted to a ball-headed column shape to better form a point-contact engagement with the recessed latch. Simultaneously, the second limiting ear 320 can be designed as a short column with a guide cone surface. During the closing process, this guide cone surface contacts the edge of the limiting structure 300 (or the inner side of the top wall of the outer box), allowing it to slide more smoothly into the closed limiting position.

[0041] This one-piece molding limiting method can reduce the number of parts and lower production costs, making it suitable for cost-sensitive large-scale production scenarios.

[0042] Example 4 This embodiment is a further functional supplement to the above embodiments, with a focus on the sealing method of the outer box 100.

[0043] In this embodiment, the top wall (and not just the side wall) of the outer box 100 adjacent to the opening 111 is also provided with a flip-up top cover. The free end of this top cover is also provided with a slot or magnetic closure, which engages with a buckle or another magnetic closure on the outer box 100. This design provides double closure: the inner side-opening box 200 is used for frequently accessed items, while the outer top cover provides stronger overall sealing and protection, suitable for scenarios with higher requirements for dust and moisture protection, such as packaging high-end tea or precision components. This side-opening packaging box of the present invention achieves reliable double locking through a clever mechanical structure, is simple to operate, and highly practical.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
