Description

Technical Field

[0001] This utility model relates to a packaging carton, and more particularly to an internally reinforced packaging carton. Background Technology

[0002] Traditional cardboard boxes are prone to deformation and damage during transportation and storage due to the weight of the contents or external pressure. This is especially true when the boxes contain heavy goods, as the bottom and sides experience significant pressure. Without special support, the boxes are easily broken or deformed, leading to damage to the goods. Furthermore, existing cardboard boxes lack the necessary internal structural support, making it difficult to achieve the required strength and stability for damage-free stacking during handling.

[0003] To address the aforementioned issues, some patent documents have proposed technical solutions involving the installation of internal support structures within the cardboard box. For example, patent document CN202222231508.5 discloses a corrugated cardboard box with internal support, in which a support plate is snapped onto the inner wall of the bottom, and the bottom is secured around the perimeter by support rods to enhance the box's stability. However, this solution primarily targets the bottom support, offering limited reinforcement to the sides of the box. Furthermore, the installation of the support structure is relatively complex, hindering the rapid assembly and use of the cardboard box.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a type of internally reinforced packaging carton that would have greater industrial value. Utility Model Content

When in the combined state, the rubber sticker is embedded in the U-shaped buckle.

[0012] Furthermore, in the aforementioned internally supported reinforced packaging carton, the side reinforcement components, support strips, and bottom reinforcement components are corrugated cardboard; or, the side reinforcement components, support strips, and bottom reinforcement components are polycarbonate sheets with a thickness of 2 to 4 millimeters.

[0013] Furthermore, in the aforementioned internally reinforced packaging carton, a reinforcing mesh is attached to the top cover hinge assembly.

[0014] Furthermore, in the aforementioned internally reinforced packaging carton, protective sleeves are fitted around the outer corners of the carton body.

[0043] 17 Reinforced mesh 18 Sheath Detailed Implementation

[0044] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0045] like Figures 1 to 10The internally reinforced packaging carton includes a carton body 1, on which several top-hinged hinge assemblies 2 are distributed. Its unique feature is that side reinforcement assemblies are installed on the inner sides of the left and right side panels or the front and rear side panels of the carton body 1. These assemblies can bear longitudinal stress and prevent excessive local deformation of the side panels of the carton body 1 due to sudden pressure. Simultaneously, a support strip 3 is connected to the top of the side reinforcement assemblies. This ensures that the top has load-bearing capacity after the top-hinged hinge assemblies 2 are closed, preventing excessive denting during stacking and avoiding pressure on the top of the contents. Furthermore, this invention also includes bottom reinforcement assemblies distributed on the inner side of the bottom plate of the carton body 1. This provides adequate support for the bottom plate, preventing abnormal wrinkling or shrinkage deformation of the bottom plate when subjected to external impact. Moreover, the top of the bottom reinforcement assemblies is connected to the support strip 3. Thus, the side reinforcement assemblies, support strip 3, and bottom reinforcement assemblies form a frame structure, which can transfer stress among themselves, preventing local stress accumulation and long-term abnormal deformation. During implementation, in order to achieve the combined positioning with the carton body 1, main positioning mechanisms are distributed on the inner surfaces of the left and right side panels, front and rear side panels, and bottom panel of the carton body 1. Sub-positioning mechanisms connected to the main positioning mechanisms are distributed at the corresponding positions of the side reinforcement components and bottom reinforcement components. In this way, after placement, the corresponding positioning of the left and right side panels, front and rear side panels, and bottom panel is achieved by the cooperation of the main positioning mechanisms and sub-positioning mechanisms.

[0046] In a preferred embodiment of this invention, the side reinforcement component is a U-shaped frame plate 4. This creates a closed shape, facilitating stress transmission at various points and minimizing localized deformation. Simultaneously, the U-shaped frame plate 4 has several connecting protrusions distributed along its upper and lower edges, forming upper protrusions 5 and lower protrusions 6, respectively. Correspondingly, the bearing strip 3 has several positioning holes 7 at both ends. During assembly, the upper protrusions 5 are inserted into the corresponding positioning holes 7 for fixing. Furthermore, the bottom reinforcement component is a U-shaped backing plate 8. This effectively reinforces the bottom edge. Moreover, the edge of the U-shaped backing plate 8 has several connecting holes 9, and the lower protrusions 6 are inserted into the corresponding connecting holes 9 for fixing. During implementation, several reinforcing ribs 10 can be distributed on the U-shaped frame plate 4. This provides better resistance to deformation. Furthermore, considering different stress transmission methods, the reinforcing ribs 10 can be distributed vertically or obliquely.

[0047] Of course, for applications requiring long-term stacking, to better support the inner vertical corners of the packaging carton and prevent the top corners from denting, the side reinforcement component can also be a rectangular support plate 11. Specifically, the upper and lower edges of the rectangular support plate 11 are each provided with several connecting protrusions, forming upper protrusions 5 and lower protrusions 6, respectively. Meanwhile, the two ends of the support strip 3 are provided with several positioning holes 7, with the upper protrusions 5 inserted into the corresponding positioning holes 7. The bottom reinforcement component is a rectangular liner 12, with several connecting holes 9 distributed along its edges, and the lower protrusions 6 inserted into the corresponding connecting holes 9.

[0048] Furthermore, in order to ensure stable connection and positioning between each reinforcing component and the carton body 1 and to avoid unnecessary shaking, the main positioning mechanism includes a main self-adhesive fastener 13 that is adhered to the inside of the carton body 1, and the secondary positioning mechanism includes secondary self-adhesive fasteners 14 that are attached to the corresponding positions of the side reinforcing components and the bottom reinforcing components. When in the combined state, the main self-adhesive fastener 13 and the secondary self-adhesive fastener 14 are adhered to each other.

[0049] Meanwhile, considering the simplification of the connection, a U-shaped buckle 15 can be used to form the main positioning mechanism. Correspondingly, the secondary positioning mechanism includes a rubber sticker 16 adhered to the corresponding position of the side reinforcing component. When in the connected state, the rubber sticker 16 is embedded within the U-shaped buckle 15. In this way, relying on the friction and expansion deformation of the rubber sticker 16, an interference fit-like installation connection can be achieved. Furthermore, the U-shaped buckle 15 can be connected to the inner wall of the packaging carton by adhesive, nailing, or other methods. Moreover, for certain non-replacement applications, both the main and secondary positioning mechanisms are adhesive strips, directly achieving bonding and positioning through these strips.

[0050] In practical implementation, the side reinforcement components, load-bearing strip 3, and bottom reinforcement components are made of corrugated cardboard. This provides adequate resistance to deformation, is easy to manufacture, and meets the deformation resistance requirements of the packaging carton even in non-multi-layer stacking conditions. It also absorbs external stresses during daily transportation, preventing excessive abnormal deformation. Furthermore, for certain higher reinforcement requirements, the side reinforcement components, load-bearing strip 3, and bottom reinforcement components are made of polycarbonate (PC) sheets with a thickness of 2 to 4 mm, preferably 3 mm. This ensures proper stress transfer and good resistance to deformation, preventing side panel bending or top corner collapse even in multi-layer stacking.

[0051] Furthermore, considering the relatively large mass of some contents, and to prevent top collapse during stacking, a reinforcing mesh 17 can be attached to the top hinge assembly 2. During implementation, wire mesh or plastic mesh can be used to construct the reinforcing mesh 17. The main purpose is to ensure that the top hinge assembly 2 has sufficient load-bearing capacity and resistance to deformation when closed. Alternatively, a honeycomb mesh made of corrugated cardboard can also be used.

[0052] Furthermore, considering the protection of corners and edges during daily stacking and transportation, protective sleeves 18 are provided on the outer corners of the carton body 1. Simultaneously, to meet the need for adequate waterproofing and prevent improper rainwater infiltration during rain exposure, a waterproof membrane (not shown in the figure) can be attached to the outside of the carton body 1. During manufacturing, aluminum foil or other waterproof films can be directly pasted onto the carton blank.

[0053] The working principle of this utility model is as follows:

[0054] Example 1

[0055] Fold and glue the blank into the carton body 1. Then, attach the main self-adhesive fastener 13 to the inside of the carton body 1. Attach the secondary self-adhesive fastener 14 to the corresponding positions of the U-shaped frame plate 4 and the U-shaped backing plate 8.

[0056] Next, place the U-shaped backing plate 8 into the carton body 1 and secure the bottom. Then, insert two U-shaped frame plates 4, connecting the U-shaped frame plates 4 to the U-shaped backing plate 8 and positioning them with the carton body 1, and reinforce the corresponding side panels.

[0057] Next, insert the contents, and fill with foam or use other methods to help position the contents.

[0058] Then, the support strip 3 is placed in and its two ends are connected to the upper end of the U-shaped frame plate 4 to form a processing frame.

[0059] Finally, close the top hinge component 2 and seal it.

[0060] Example 2

[0061] Install the U-shaped buckle 15 at a predetermined position inside the carton body 1, preferably on the side of the middle section of the side panel of the carton body 1. Then, attach the rubber sticker 16 to the bottom corner of the rectangular support plate 11.

[0062] Next, the rectangular liner 12 is placed inside the carton body 1, and the bottom is secured. Then, two rectangular support plates 11 are placed in and joined using corresponding protrusions. At the same time, the rubber pads 16 are embedded into the corresponding U-shaped buckles 15 for auxiliary positioning.

[0063] Next, the contents are placed in. Then, the support strip 3 is placed in, connecting its two ends to the top of the rectangular support plate 11. Subsequently, reinforcing mesh 17 is attached to the inside or outside of the paired hinge assemblies 2 for additional reinforcement.

[0064] Finally, close the top hinge component 2 and encapsulate it.

[0065] As can be seen from the above textual description and the accompanying drawings, the present invention has the following advantages:

[0066] 1. It can achieve pressure resistance and deformation resistance at the bottom and side panels of the carton body, effectively protecting the contents.

[0067] 2. It can work with the load-bearing strips to form a complete internal frame structure, achieving better load-bearing and protective effects, and can distribute stress to avoid abnormal deformation of the carton caused by excessive local stress.

[0068] 3. A reinforcing mesh can be added to prevent the top from collapsing and the top of the contents from being improperly squeezed during stacking.

[0069] 4. The side reinforcement components can be distributed individually or completely on the inner side of the left and right side panels or the front and rear side panels as needed to meet different compressive load requirements.

[0070] 5. The main positioning mechanism and the auxiliary positioning mechanism work together to provide auxiliary positioning for the side reinforcement components and the bottom reinforcement components.

[0071] 6. The overall structure is simple and can be modified from existing packaging cartons, making it easy to implement.

[0073] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
