Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging paper box technology, specifically to a honeycomb core composite impact-resistant color box. Background Technology
[0002] Interlocking cartons / boxes typically consist of two or more pieces, commonly known as top-and-bottom cartons. Their characteristic is that the lid and the carton (sometimes including the bottom) are separate, offering good sturdiness and compressive strength. In structural design, the bottom dimensions should be calculated first, and then the manufacturing dimensions of the lid should be determined based on the external dimensions of the bottom. The key feature is that the carton body and lid are separate and only interlocked to form the carton body. When the carton is placed upright, the lid can partially or completely cover the carton body. This type of carton is well-suited for packaging requiring high stacking load strength.
[0003] To improve the impact and cushioning function of cardboard boxes, existing technologies, such as the patent with publication number CN215664856U, disclose a high-strength, tear-resistant, and environmentally friendly cardboard box with impact and cushioning function. This is achieved by setting an inner box supported by damping strips and support blocks inside the outer box to achieve cushioning and shock absorption. However, the structure of this cardboard box is too complex, which makes it difficult to manufacture and results in high production costs. Utility Model Content

[0024] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.
[0025] See Figure 1-4 In one embodiment of this utility model, a honeycomb core composite impact-resistant color box includes:
[0026] Outer box 1, the outer box 1 is a rectangular tube structure with openings at both ends;
[0027] Inner box 2 has the same structure as outer box 1, which is also a rectangular tube structure with openings at both ends. The inner box 2 is smaller than outer box 1. Specifically, the length, width and height of inner box 2 are smaller than those of outer box 1. Inner box 2 is coaxially arranged inside outer box 1.
[0028] Four honeycomb panels 3 are provided, corresponding to the four sides of the outer wall of the inner box 2. After installation, the honeycomb panels 3 are placed within the annular space formed between the inner and outer boxes. In implementation, the honeycomb panels 3 are bonded to the outer wall of the inner box 2 by adhesive application. The honeycomb panels 3 are slidably connected to the inner wall of the outer box 1 without adhesive application. In other words, the honeycomb panels and the inner box are bonded together by adhesive application, simplifying assembly, improving production efficiency, and ensuring that the honeycomb panels will not be misaligned or fall off when the inner box moves. In particular, the honeycomb core of the honeycomb panel 3 is axially... (i.e., the direction of the ducts) are all perpendicular to the outer wall of the inner box to which they are attached, that is, perpendicular to the corresponding inner wall of the outer box, to ensure maximum compressive strength in the main pressure direction; in implementation, the size of the honeycomb panel 3 is smaller than the size of the outer wall of the corresponding inner box 2; the four honeycomb panels form an efficient lateral buffer layer between the inner box and the outer box; the setting of the honeycomb core axis perpendicular to the wall surface allows the honeycomb panel to fully utilize the high axial compressive strength of its core material to absorb impact energy when subjected to impact or stacking pressure from the side of the color box, effectively protecting the contents;
[0029] The lid 4 includes a rectangular box-shaped lid body with an opening at the top, and a cushioning pad 41 located at the lower end of the lid body. The lid body is slidably fitted into the opening at the top of the outer box 1 and the upper side of the inner box 2. The lower end of the lid body abuts against the inner box 2, and the upper end of the lid body is flush with the top of the outer box 1. The cushioning pad 41 is made of low-cost plastic foam. The cushioning pad 41 is located inside the inner box 2, and the outer edge dimension of the cushioning pad 41 is adapted to the inner circumference dimension of the inner box 2. In this way, the cushioning pad 41 can limit the circumferential rotation of the inner box 2, ensuring the stability of the inner box 2 after it is installed.
[0030] The fixed cover 5 has the same structure as the box cover 4, which reduces the types of molds, simplifies production management and material preparation, and significantly reduces production costs. The fixed cover 5 is fixed to the bottom inner side of the outer box 1 by adhesive bonding. Specifically, the cover body of the fixed cover 5 is symmetrically arranged with the cover body of the box cover 4. The outer wall of the cover body of the fixed cover 5 is bonded to the inner wall of the outer box 1, and the upper end of the cover body of the fixed cover 5 abuts against the lower end of the inner box 2. In this way, the fixed cover 5 and the box cover 4 together realize the bidirectional (top and bottom) movement of the inner box inside the color box. Longitudinal and circumferential limiting effectively prevent the inner box from shaking, shifting, or rotating during transportation, improving the overall structural stability; the lower end of the fixed cover 5 is flush with the bottom end of the outer box 1, making the color box look flat and beautiful when closed; the cushioning pad of the fixed cover 5 is located inside the inner box 2; the plastic foam cushioning pads inside the box cover and the fixed cover are respectively embedded in the upper and lower ends of the inner box, directly contacting the contents (or inner packaging), providing reliable top and bottom cushioning; at the same time, the design of the cushioning pad embedded in the inner box enhances the circumferential stability of the inner box;
[0031] Pull ring 6 is located at the center of the top outer surface of the lid 2 to facilitate the application of force to open the lid 2.
[0032] In this embodiment, the honeycomb panel 3 (space) provides lateral cushioning, and the upper and lower cushioning pads provide top and bottom cushioning, giving the color box a high impact resistance.
[0033] In one embodiment, the lid 4 has an annular EVA foam strip or rubber strip at the top of the outer wall of the lid and / or the inner wall of the outer box 1 in the fitting contact area, so as to improve the stability of the lid 4 after it is closed, and at the same time ensure that the internal space of the color box is sealed and moisture is prevented.
[0034] Through this technical solution, the impact-resistant color box achieves excellent impact resistance, internal structural stability, and convenient operation by using an innovative honeycomb panel lateral buffer structure between the inner and outer boxes, a symmetrical upper and lower lid embedded buffer design, and structural uniformity of key components. At the same time, it takes into account the simplicity of production and cost-effectiveness, making it particularly suitable for product packaging that requires a high level of protection.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
