Description

Technical Field

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

[0002] In the field of product sales and display, paper packaging boxes have become the mainstream packaging choice for industries such as food, jewelry, and cultural and creative products due to their advantages such as low cost, environmental friendliness, easy degradation, and strong printability. They not only fulfill the basic functions of protecting goods and facilitating transportation, but also require reasonable structural design to assist in product display—especially in scenarios such as supermarket displays and trade show promotions, where the display effect of packaging boxes directly affects consumers' purchasing intentions. A high-quality display structure can highlight product features and enhance the added value of the product. However, existing paper packaging boxes have significant functional limitations: their core housing frame is mostly a fixed cuboid or cube structure, which can only be placed horizontally and cannot be adjusted at an angle to meet display needs. They often require the use of stands, display platforms, and other auxiliary tools to achieve the desired display effect. This not only increases display costs but also, due to the poor compatibility of these additional tools with the packaging boxes, limits display scenarios, makes operation cumbersome, and significantly reduces practicality. Therefore, developing a paper packaging box with an adjustable frame angle that can achieve efficient display without additional auxiliary tools has become an urgent need to improve the practicality of packaging and help promote products.

Detailed Implementation

[0015] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0016] Please see Figure 1-7 A paper packaging box includes a packaging box body 1, a cover plate 2 installed on the packaging box body 1, and an inner box body 3 disposed inside the packaging box body 1. The packaging box body 1 provides a basic framework for the entire packaging, protecting the inner box body 3 and the goods inside from external impacts. The cover plate 2 can be opened and closed. When closed, it seals the packaging box, protecting the goods from dust and moisture. When opened, it facilitates the removal and display of the goods. The inner box body 3 directly carries the goods and is the core carrier for achieving angle-adjustable display.

[0017] The inner box 3 is rotatably mounted via the mounting shaft 4. An angle adjustment assembly is also provided on the outside of the packaging box body 1. This assembly includes braking units symmetrically mounted on both sides of the packaging box body 1. Each braking unit includes a hollow disc 5, a ratchet 6, a pawl 7, and a spring 8. Circular grooves are symmetrically formed on both side walls of the packaging box body 1. The hollow disc 5 is fixedly embedded within these grooves, and the ratchet 6 is rotatably mounted inside the hollow disc 5. A pawl 7, compatible with the ratchet 6, is also mounted inside the hollow disc 5 via the spring 8. The ratchet 6 is coaxially fixedly mounted on the mounting shaft 4. A knob 9 connected to the pawl 7 is also mounted outside the hollow disc 5. In the side braking unit, the ratchet 6 and pawl 7 are arranged in a mirror image. The mounting shaft 4 serves as the rotation axis of the inner box 3, ensuring stability during angle adjustment. The circular groove provides installation space for the hollow disc 5, which protects the ratchet 6 and pawl 7 from damage. The spring 8 pushes the pawl 7 to always engage with the ratchet 6. The mirror-arranged braking unit restricts the clockwise and counterclockwise rotation of the mounting shaft 4 respectively, thus fixing the tilt angle of the inner box 3 without the need for additional auxiliary tools, solving the problem of requiring a support frame for display in the background technology. The knob 9 can be manually lifted to release the pawl 7, facilitating angle adjustment and making operation convenient.

[0018] Please see Figure 6 The bottom surface of the inner box 3 is also provided with multiple columnar embedded grooves, and an ejector spring 10 is installed in the embedded groove. When the knob 9 is turned to release the lock, the ejector spring 10 can lift the inner box 3 upward, so that the inner box 3 is misaligned with the packaging box body 1, providing initial assistance for the inner box 3 to flip, and making it convenient for the operator to quickly adjust the angle.

[0019] Please see Figure 1 , Figure 4 and Figure 7 The packaging box body 1 has a notch 11 on the side away from the cover plate 2. The cover plate 2 is also provided with a rotating plate 12. The rotating plate 12 is fitted with the notch 11 with a gap. Both the rotating plate 12 and the inner box body 3 are provided with multiple magnetic buckles 13. The notch 11 provides space for the rotating plate 12 to be accommodated and rotated. The rotating plate 12 can rotate around the cover plate 2. Rotating the rotating plate 12 makes it fit against the inner box body 3. It is fixed by magnetic buckles 13, which can realize the sealing of the packaging box body 1 by the cover plate 2, and further enhance the stability of the packaging box body 1 when sealed.

[0020] Please see Figure 7 The notch 11 is also provided with a slot 14 for engaging the rotating plate 12. The slot 14 makes it easy for the operator to insert their fingers to engage the rotating plate 12, improving ease of use and preventing the rotating plate 12 from being too tightly fitted to the notch 11, which would make it difficult to open.

[0021] Please see Figure 1 , Figure 4 and Figure 7A connecting rope 15 is symmetrically installed between the cover plate 2 and the side wall of the packaging box body 1. The connecting rope 15 can limit the maximum flipping angle of the cover plate 2, so as to prevent the cover plate 2 from taking up too much space when fully unfolded. It is especially suitable for scenarios with limited space, such as supermarket shelves and exhibition booths, and improves the practicality of display.

[0022] Please see Figure 1 and Figure 7 A reinforcing unit is also fixedly installed on the side of the cover plate 2 between the two connecting ropes 15. The reinforcing unit includes multiple reinforcing ribs 16 bonded to the side of the cover plate 2. The multiple reinforcing ribs 16 are staggered and form multiple reinforcing grooves 17 in a "well" structure. The staggered reinforcing ribs 16 and the "well" reinforcing grooves 17 can disperse the impact force on the cover plate 2, enhance the structural strength of the cover plate 2, prevent the paper cover plate 2 from being deformed and damaged due to collision, and extend the service life of the packaging box.

[0023] Please see Figure 1 and Figure 7 The reinforcing groove 17 is also equipped with a cushioning sponge 18. When the cover 2 is closed, the cushioning sponge 18 fits against the top of the inner box 3 and can cushion the impact on the cover 2 during transportation or carrying, so as to prevent the goods from being worn or damaged due to collision. At the same time, it can also protect the top of the goods when they are displayed.

[0024] Please see Figure 2 and Figure 4 The bottom surface of the packaging box body 1 is also provided with a protective plate 19. Each of the four corners of the protective plate 19 is provided with a vertically arranged protective corner protector 20. The protective corner protector 20 is glued to the four corners of the packaging box body 1. The protective plate 19 enhances the strength of the bottom of the packaging box and prevents the bottom from deforming when placed. The protective corner protector 20 is made of wear-resistant materials (such as cardboard or plastic sheet) to protect the corners of the packaging box from collision damage, improve the overall protective performance, and meet the needs of long-distance transportation.

[0025] When displaying goods, the rotating plate 12 is disengaged from the notch 11 by using the slot 14, and the cover 2 is flipped upwards. The connecting rope 15 limits the flipping angle of the cover 2 to save space. The knob 9 on one side of the packaging box body 1 is turned to lift the pawl 7 on that side to release the ratchet 6. The inner box 3 is offset from the packaging box body 1 by the push of the ejector spring 10. The inner box 3 is manually flipped to the ideal display angle. The knob 9 is released, and the pawl 7 on that side re-engages with the ratchet 6 under the action of the spring 8. At the same time, the pawl 7 of the braking unit on the other side always locks the ratchet 6, fixing the angle of the inner box 3 in both directions. When storing goods, the knob 9 is turned to release the lock, the inner box 3 is reset, the ejector spring 10 is compressed, the cover 2 is closed, the rotating plate 12 returns to the notch 11, and the inner box 3 is further fixed by the magnetic snap 13. The cushioning sponge 18 fits against the top of the goods to provide protection, and the protective corner protector 20 and the protective plate 19 ensure transportation safety. This design addresses the shortcomings of the prior art, which required auxiliary tools for display, through an "adjustable angle + stable fixation" structure, thus balancing both display and protection.

[0026] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
