Description

Technical Field

[0001] This invention relates to the field of packaging boxes, and more specifically to a packaging box that allows for stable horizontal lifting. Background Technology

[0002] Traditional packaging boxes typically consist of a box body and a handle at the top for easy carrying of the contents. In current technology, handles are often independently installed ropes, plastic handles, or integrally molded plate structures with the box body. However, this design still has several shortcomings in practical use: firstly, the box is prone to tilting during handling, causing items inside to shift or even fall out; secondly, the handle structure often applies concentrated stress to the hand, which can cause discomfort or marks after prolonged use. Furthermore, most handle structures lack effective reinforcement design, making them susceptible to deformation or breakage under load or repeated use.

[0003] Especially for packaging boxes that need to remain level (such as those carrying fragile items, liquid containers, or precision instruments), existing handle designs struggle to maintain the box's horizontal stability throughout the lifting process. Some designs attempt to improve stress distribution by increasing handle width or thickening materials, but this leads to increased material costs, bulkier structures, or inconvenient folding and storage. Furthermore, existing packaging box handles often lack an effective linkage support mechanism with the box body, failing to form a stable mechanical structure during lifting, further limiting their load-bearing capacity and user experience.

[0004] Therefore, there is an urgent need for a new type of packaging box structure that can ensure the box remains level and stable while providing sufficient structural strength and load-bearing reliability, while guaranteeing comfortable handling. Summary of the Invention

[0005] To address the above problems, the present invention provides a packaging box with horizontally stable lifting mechanism:

[0006] A horizontally stable carrying packaging box includes a box body and two integrated handles connected to the upper outer edge of the box body. The handles are circular plate-shaped structures. The box body and the two handles are arranged in an isosceles triangle. The box body is horizontally positioned. The upper ends of the two handles abut against each other. The upper part of the two handles near the abutment point has a hollow straight groove. One or both straight grooves have a flip plate adapted to the straight groove. The upper end of the flip plate is integrally fixed to the upper inner side of the straight groove. When the flip plate is located in the straight groove, there is a scribed gap between the flip plate and the straight groove. When the flip plate is disengaged from the straight groove and flipped inward to a horizontal position, the flip plate abuts against the upper end of the straight groove of the other handle. At this time, the upper parts of the two handles and the flip plate form an isosceles triangle arrangement.

[0007] Preferably, both handles have a rotating plate at their straight grooves, and the two rotating plates are closely fitted together, with the upper rotating plate abutting against the lower rotating plate at the turning bend opposite the handle. When both handles have rotating plates that are fitted together and mutually restrictive, the two rotating plates support each other, forming an interlocking structure. The upper rotating plate abutting against the turning bend of the lower rotating plate, and the lower rotating plate restricting the upper rotating plate, further enhances the rigidity and stability of the overall structure, enabling it to withstand greater weight.

[0008] Preferably, the opposing surfaces of the two flip panels are adhesively or magnetically attached to each other. The adhesive attachment method is via Velcro, while the magnetic attachment method is via magnetically attached surfaces. The flip panels and handle are integrated, requiring no additional assembly, resulting in high connection strength and avoiding the risk of additional parts falling off. The preferred connection method, such as Velcro or magnetic attachment, provides a flexible and reliable fixation method, ensuring the flip panels remain securely within the slot when not in use.

[0009] Preferably, the box body is a paper box structure, the box body includes an upper cover plate and a lower cover plate, the upper cover plate has inner extension side plates on both sides, the lower cover plate has outer extension side plates on both sides, the inner extension side plates are bonded to the inner side of the outer extension side to form the two sides of the box body, and the upper ends of the two outer extension side plates are integrally connected to handles.

[0010] Preferably, a metal mesh layer is adhered to the upper surface of the top cover. This metal mesh layer is composed of elastic metal wires with a mesh structure, and its upper surface is used to support objects. The metal mesh layer not only increases the yield strength of the cardboard, allowing the upper surface of the box to support new objects, but also provides a certain surface roughness to prevent objects from sliding. By integrating a metal mesh layer into the top cover of the box, the paper packaging box is given additional yield strength and load-bearing capacity, allowing its upper surface to be safely stacked or supporting other objects, thus expanding its functionality. The natural roughness of the metal mesh layer provides an anti-slip effect. Its upward-curving outer edge, together with the handles on both sides, forms an enclosed limiting area, effectively preventing stacked items from sliding off, further enhancing safety and versatility.

[0011] Preferably, the metal mesh layer has upward-curving outer edges on both sides corresponding to the upper cover plate, and the two outer edges and two handles constitute a limiting structure that surrounds the metal mesh layer.

[0012] This application has the following beneficial effects:

[0013] 1. The box body and two handles form an isosceles triangle layout, and when lifted, the two handles and the flip panel again form an isosceles triangle. This double-triangular mechanical stability structure ensures that the box body remains horizontal during lifting, effectively preventing items inside from shifting, colliding, or even spilling due to tilting. It is particularly suitable for transporting fragile items, liquids, or precision objects. The horizontal nature of the box body maximizes its load-bearing area, stabilizes the center of gravity of the items, and avoids the risk of items breaking out of the box during movement due to tilting.

[0014] 2. Traditional openwork handles exert direct stress on the palm due to the groove edges, causing discomfort or even injury during prolonged use. This invention addresses this by incorporating a flip plate within the straight groove. When lifting, the user's palm is supported by the flip plate surface, significantly increasing the contact area and transforming concentrated line stress into dispersed surface stress. This fundamentally eliminates the problem of pressure marks, resulting in a more comfortable and effortless lifting experience. Users simply pass their fingers through the straight grooves of the two handles and naturally grip the flip plate to lift, a ergonomic, intuitive, and convenient design.

[0015] 3. When in the carrying position, the flip plate flips over, and its free end abuts against the upper end of the straight groove of the other handle. This design is equivalent to adding a "support beam" between the force points of the handle structure, transforming the unidirectional bending that the handle plate might have originally caused into a stable triangular truss structure. This greatly improves the handle's resistance to bending, prevents irreversible deformation or creases under heavy loads, and extends the service life of the packaging box.

[0023] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described with reference to Examples 1-3.

[0024] Example 1: As Figure 1-4 As shown, a horizontally stable carrying packaging box includes a box body 1 and two integrated handles 2 connected to the upper outer edges of the box body 1. The box body 1 is a cardboard box structure, and includes an upper cover plate 6 and a lower cover plate 7. The upper cover plate 6 has inner side plates 8 on both sides, and the lower cover plate 7 has outer side plates 9 on both sides. The inner side plates 8 are glued to the inner surfaces of the outer side plates to form the two sides of the box body 1. The upper ends of the two outer side plates 9 are integratedly connected to the handles 2.

[0025] The handle 2 has a circular plate-like structure. The box body 1 and the two handles 2 are arranged in an isosceles triangle. The box body 1 is horizontal. The upper ends of the two handles 2 abut against each other. The upper part of the two handles 2 has a hollow straight groove 3 near the abutment point. One of the straight grooves 3 has a flip plate 4 that fits into the straight groove 3. The upper end of the flip plate 4 is integrally fixed to the upper inner side of the straight groove 3. When the flip plate 4 is in the straight groove 3, there is a scribed gap between the flip plate 4 and the straight groove 3. When the flip plate 4 is disengaged from the straight groove 3 and flipped inward to a horizontal position, the flip plate 4 abuts against the upper end of the straight groove 3 of the other handle 2. At this time, the upper parts of the two handles 2 and the flip plate 4 form an isosceles triangle arrangement.

[0026] Example 2: As Figure 5 As shown, a horizontally stable carrying packaging box includes a box body 1 and two integrated handles 2 connected to the upper outer edge of the box body 1. The box body 1 is a cardboard box structure. The box body 1 includes an upper cover plate 6 and a lower cover plate 7. The upper cover plate 6 has inner extension side plates 8 on both sides, and the lower cover plate 7 has outer extension side plates 9 on both sides. The inner extension side plates 8 are glued to the inner side surface of the outer extension side to form the two sides of the box body 1. The upper ends of the two outer extension side plates 9 are integratedly connected to the handles 2.

[0027] The handle 2 has a circular plate-like structure. The box body 1 and the two handles 2 are arranged in an isosceles triangle. The box body 1 is horizontal. The upper ends of the two handles 2 abut against each other. The upper part of the two handles 2 has a hollow straight groove 3 near the abutment point. A flip plate 4 is provided in the two straight grooves 3 to fit the straight grooves 3. The upper end of the flip plate 4 is integrally fixed to the upper inner side of the straight groove 3. When the flip plate 4 is in the straight groove 3, there is a scribed gap between the flip plate 4 and the straight groove 3. When the flip plate 4 is disengaged from the straight groove 3 and flipped inward to a horizontal position, the flip plate 4 abuts against the upper end of the straight groove 3 of the other handle 2. At this time, the upper parts of the two handles 2 and the flip plate 4 form an isosceles triangle arrangement. The two flip plates 4 are closely fitted together, with the upper flip plate 4 abutting against the turning bend of the lower flip plate 4 relative to the handle 2. The lower flip plate 4 provides a corresponding limiting effect on the upper flip plate 4. The two flip panels 4 are bonded together by adhesive tape 5. Both adhesive and magnetic bonding methods are acceptable, with magnetic bonding achieved by using magnetic adhesive surfaces to attract each other.

[0028] Example 3: As Figure 6 As shown, a horizontally stable carrying packaging box includes a box body 1 and two integrated handles 2 connected to the upper outer edge of the box body 1. The box body 1 is a cardboard box structure. The box body 1 includes an upper cover plate 6 and a lower cover plate 7. The upper cover plate 6 has inner extension side plates 8 on both sides, and the lower cover plate 7 has outer extension side plates 9 on both sides. The inner extension side plates 8 are glued to the inner side surface of the outer extension side to form the two sides of the box body 1. The upper ends of the two outer extension side plates 9 are integratedly connected to the handles 2.

[0029] The handle 2 has a circular plate-like structure. The box body 1 and the two handles 2 are arranged in an isosceles triangle. The box body 1 is horizontal. The upper ends of the two handles 2 abut against each other. The upper part of the two handles 2 has a hollow straight groove 3 near the abutment point. A flip plate 4 is provided in the two straight grooves 3 to fit the straight grooves 3. The upper end of the flip plate 4 is integrally fixed to the upper inner side of the straight groove 3. When the flip plate 4 is in the straight groove 3, there is a scribed gap between the flip plate 4 and the straight groove 3. When the flip plate 4 is disengaged from the straight groove 3 and flipped inward to a horizontal position, the flip plate 4 abuts against the upper end of the straight groove 3 of the other handle 2. At this time, the upper parts of the two handles 2 and the flip plate 4 form an isosceles triangle arrangement. The two flip plates 4 are closely fitted together, with the upper flip plate 4 abutting against the turning bend of the lower flip plate 4 relative to the handle 2. The lower flip plate 4 provides a corresponding limiting effect on the upper flip plate 4. The two flip panels 4 are bonded together by adhesive tape 5. Both adhesive and magnetic bonding methods are acceptable, with magnetic bonding achieved by using magnetic adhesive surfaces to attract each other.

[0030] A metal mesh layer 10 is bonded to the upper surface of the top cover plate 6. The metal mesh layer 10 is composed of elastic metal wires with a mesh structure, and its upper surface is used to support objects. The metal mesh layer 10 not only increases the yield strength of the cardboard, allowing the upper surface of the box to support new objects, but also provides a certain surface roughness to prevent objects from sliding. The metal mesh layer 10 has upward-curving outer edges 11 on both sides corresponding to the top cover plate 6. The two outer edges 11 and the two handles 2 form a limiting structure that encloses the metal mesh layer 10.
