Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a packaging box with an inner tray. Background Technology

[0002] Packaging boxes are an indispensable part of modern commodity circulation. They not only fulfill the core function of protecting products from damage during transportation and storage, but also increasingly become an important medium for brand display and enhancing user experience. Especially for high-value or fragile products such as electronic products, cosmetics, high-end gifts, and alcoholic beverages, their packaging usually includes an inner tray structure.

[0003] Currently, most packaging boxes on the market with inner trays are made of plastic (such as PVC, PS), foam (such as EPS, EPE), or paper materials through processes such as die-cutting and vacuum forming. The inner tray has a receiving cavity that adapts to the shape of the product. When packaging, the product is embedded in this receiving cavity, and the product is fixed and protected by the wrapping and cushioning of the inner tray.

[0004] However, this traditional packaging method has the following significant drawbacks:

[0005] To ensure protective performance, the inner tray often covers most of the product's volume, leaving it in a "semi-hidden" state after opening the box. Consumers cannot immediately see the product's full appearance and design details, severely weakening the product's visual impact and the sense of occasion when unboxing, thus affecting the efficient transmission of brand value.

[0006] Users need to "pry" or "remove" the product from its tightly wrapped inner tray, which is inconvenient. This removal action may not only be difficult due to excessive friction, but in some cases there is even a risk that the product may slip off due to improper operation, failing to provide users with a smooth and elegant unboxing experience.

[0007] Therefore, we propose a packaging box with an inner tray. Utility Model Content

[0008] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a packaging box with an inner tray.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a packaging box with an inner tray, comprising a packaging box base and a packaging box cover, wherein a plastic inner tray is fixedly connected to the inner surface of the packaging box base, and the packaging box cover is sleeved on the outer surface of the plastic inner tray, wherein a rotating platform is rotatably connected to the inner surface of the plastic inner tray, and a spring rotating assembly is installed between the rotating platform and the plastic inner tray.

[0010] The top of the rotating platform is fixedly fitted with a bottom protective sponge;

[0011] The top of the rotating platform and the top of the plastic inner tray are connected together by a linkage limiting pin, and the linkage limiting pin is fixedly connected to the top of the inner cover of the packaging box.

[0012] The inside of the packaging box cover is equipped with a protective component.

[0013] Furthermore, the spring rotation assembly includes a plastic shaft, which is fixedly connected to the bottom of the rotary table. A spiral spring is fixedly sleeved on the outer surface of the plastic shaft, and the other end of the spiral spring is fixedly connected to the inner plastic support. The energy released after the spiral spring is twisted is used as a stable and continuous rotational power, ensuring that the rotary table starts to rotate smoothly and can complete multiple rotations.

[0014] Furthermore, the top of the rotary table has a first limiting groove on its outer edge and its outer wall, and the top of the plastic inner support has a second limiting groove on its inner edge and its inner wall. The first limiting groove and the second limiting groove are accurately aligned in the closed state, forming a locking channel for inserting an I-shaped pin. This design achieves reliable locking between the rotary table and the fixed inner support.

[0015] Furthermore, the linkage limiting pin includes an I-shaped pin, which is inserted into the first limiting groove and the second limiting groove. A long rope is fixedly connected to the top of the I-shaped pin, and the top of the long rope is fixedly connected to the inner top of the packaging box cover. The long rope links the I-shaped pin with the packaging box cover, so that the opening action and the unlocking action are naturally connected.

[0016] Furthermore, the protective component includes four edge protective sponges and a top protective sponge. The edge protective sponges are symmetrically and fixedly connected to the four inner walls of the packaging box cover, and the top protective sponge is fixedly connected to the inner top of the packaging box cover. The protective component and the bottom protective sponge together form a complete three-dimensional buffer structure that can protect the packaged items.

[0017] Furthermore, the top of the bottom protective sponge is provided with an item slot, which facilitates the positioning and placement of items.

[0018] The beneficial effects of this utility model are:

[0019] In use, this invention utilizes a spring-loaded rotating component within the plastic inner tray and a limiting pin structure linked to the packaging box lid. When the box is opened, the lifting motion of the lid automatically releases the limiting pin, releasing the potential energy of the spiral spring and driving the rotating platform and the product it supports to rotate smoothly. This allows the product to be dynamically and completely displayed to the consumer the moment it is opened, effectively solving the problems of insufficient visual presentation and inconvenient removal caused by overly tight inner trays in traditional packaging. It significantly enhances the sense of ceremony, visual impact, and user experience of opening the box. Simultaneously, the bottom protective sponge and protective components ensure the product's safety during transportation. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-3As shown, a packaging box with an inner tray is disclosed, comprising a packaging box base 1 and a packaging box cover 2. A plastic inner tray 7 is fixedly connected to the inner surface of the packaging box base 1, and the packaging box cover 2 is sleeved on the outer surface of the plastic inner tray 7. A rotating platform 9 is rotatably connected to the inner surface of the plastic inner tray 7. A spring rotating assembly is installed between the rotating platform 9 and the plastic inner tray 7. The spring rotating assembly includes a plastic shaft 13, which is fixedly connected to the bottom of the rotating platform 9. The plastic shaft 13 and the rotating platform 9 are integrally injection molded to ensure the connection strength between the two. The outer surface of the plastic shaft 13 is fixedly connected to the inner surface of the rotating platform 9. A spiral spring 12 is fitted onto the inner plastic support 7, and the other end of the spiral spring 12 is fixedly connected to the inner plastic support 7. The spiral spring 12 is made of stainless steel strip to ensure good elasticity and fatigue life. In actual production, a spring with moderate torque is selected rather than a particularly strong one. Excessive torque will cause rapid rotation or even vibration. Moderate torque provides smooth start-up and speed. Secondly, there is slight frictional resistance between the rotary table 9 and the inner plastic support 7. The product itself and the rotary table 9 have a certain mass (inertia), and starting and stopping require a process, which makes the movement look more stable and elegant.

[0028] The top of the rotating platform 9 is fixedly fitted with a bottom protective sponge 8, and the top of the bottom protective sponge 8 has an item slot.

[0029] The top of the rotating platform 9 and the top of the plastic inner tray 7 are connected by a linkage limiting pin, and the linkage limiting pin is fixedly connected to the top of the inner side of the packaging box cover 2. The top of the rotating platform 9 has a first limiting groove 11 on its outer edge and its outer wall, and the top of the plastic inner tray 7 has a second limiting groove 10 on its inner edge and its inner wall. The linkage limiting pin includes an I-shaped pin 6, which is inserted into the first limiting groove 11 and the second limiting groove 10. A long rope 5 is fixedly connected to the top of the I-shaped pin 6, and the top of the long rope 5 is fixedly connected to the top of the inner side of the packaging box cover 2. The I-shaped pin 6 is made of plastic and is inserted into the first limiting groove 11 and the second limiting groove 10 by compression, which increases the movement resistance of the I-shaped pin 6 and prevents the I-shaped pin 6 from disengaging from the first limiting groove 11 and the second limiting groove 10 when the entire packaging box is inverted.

[0030] The inner side of the packaging box cover 2 is equipped with a protective component, which includes four edge protective sponges 4 and a top protective sponge 3. The edge protective sponges 4 are symmetrically and fixedly connected to the four inner walls of the packaging box cover 2, and the top protective sponge 3 is fixedly connected to the inner top of the packaging box cover 2.

[0031] Working principle: When the packaging box is in the closed state, the packaging box cover 2 is tightly fitted onto the plastic inner tray 7. At this time, the I-pin 6 is inserted into the second limiting groove 10 and the first limiting groove 11, which plays a crucial locking role.

[0032] Restricting rotation: The I-shaped pin 6 acts like a latch, locking the rotary table 9 to the fixed plastic inner support 7, preventing any rotation of the rotary table 9.

[0033] Compression spring: In the locked state, the spiral spring 12 pre-tightly installed on the plastic shaft 13 at the bottom of the rotary table 9 is in a state of torsional energy storage, storing elastic potential energy.

[0034] Meanwhile, the protective components (top protective sponge 3 and edge protective sponge 4) inside the packaging box cover 2 press against the top and sides of the item, working together with the bottom protective sponge 8 embedded on the rotating platform 9 to form a comprehensive and flexible clamping and cushioning of the item from six sides, ensuring its absolute safety during transportation.

[0035] When the user lifts the lid of the packaging box 2, a smooth, automated display process occurs:

[0036] As the packaging box cover 2 moves upward, and just before it is fully opened, the long rope 5 is taut. Then, as the packaging box cover 2 moves again, the I-shaped pin 6 connected to it via the long rope 5 is simultaneously pulled out from the first limiting groove 11 and the second limiting groove 10. The mechanical lock between the rotating platform 9 and the plastic inner tray 7 is released.

[0037] Once the lock is released, the compressed spiral spring 12 immediately releases its stored elastic potential energy. This energy drives the plastic shaft 13 and causes the entire rotary table 9 to rotate slowly relative to the fixed plastic inner support 7.

[0038] The items embedded in the slot rotate smoothly along with the rotating platform 9, supported by the bottom protective sponge 8. When the user removes the packaging box cover 2, what they see is not a static product, but a product that is elegantly rotating and actively presenting its full appearance, creating a strong visual impact and a sense of unboxing ritual.

[0039] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
