Abstract
Description
Technical Field
[0001] This application relates to the field of packaging box technology, specifically a beer packaging box. Background Technology
[0002] Currently, cardboard boxes or plastic boxes are widely used as transport containers in the beer packaging industry.
[0003] Chinese utility model patent CN218807541 discloses a beer packaging box. This design improves overall cushioning performance by placing a buffer cardboard between a first and second protective box; the design of limiting support columns enhances the stability and compression resistance of the packaging box; beer bottles are divided and fixed in placement slots, with the bottom inserted into the bottle insertion and fixing slot, the middle part cooperating with the limiting plate through a bottle limiting hole, and the top constrained by a docking limiting slot, forming a multi-layer limiting structure that effectively avoids collisions between bottles. However, its bottle insertion and fixing slots only achieve positioning through shape adaptation and lack elastic cushioning materials or structures. In actual transportation, the bottom of the beer bottle is susceptible to vertical vibration or drop impact, and the rigid fixing slot cannot effectively absorb energy, leading to stress concentration at the bottle bottom and a high risk of breakage. Especially in long-distance transportation or complex road conditions, this defect may significantly increase the product breakage rate, thereby affecting transportation costs and user experience.
[0004] Therefore, this application provides a beer packaging box to solve the above-mentioned problems. Utility Model Content
[0005] This application provides a beer packaging box, which aims to solve the problems mentioned in the background art, such as the existing beer bottle insertion and fixing grooves only achieving rigid positioning through shape adaptation, lacking elastic cushioning materials or structures, resulting in the bottle bottom not being able to effectively absorb energy when subjected to vertical impact during transportation, and being prone to cracking due to stress concentration.
[0006] To achieve the above objectives, this application provides the following technical solution: a beer packaging box, comprising an outer box and an inner box disposed inside the outer box, wherein a cushioning cardboard is disposed between the outer box and the inner box;
[0007] To reduce the impact on the bottom of the beer bottle: the inner casing is equipped with an elastic cushioning pad to reduce the impact on the bottom of the beer bottle. The top of the elastic cushioning pad has a fixing groove for the bottom of the beer bottle to be inserted. The fixing groove has multiple elastic protrusions that abut against the beer bottle, and the multiple elastic protrusions are distributed in a spiral shape within the fixing groove. Through the cooperation of the elastic cushioning pad and the spirally distributed elastic protrusions, the protective performance of the bottom of the beer bottle can be improved from two dimensions: "flexible cushioning" and "multi-point restraint". The flexible material of the elastic cushioning pad can absorb the vertical vibration or drop impact energy during transportation, avoiding stress concentration and breakage of the bottle bottom due to rigid contact. The fixing groove restricts the large displacement of the beer bottle, and the spirally distributed elastic protrusions provide circumferential friction through multi-point contact, which not only prevents the bottle from shaking and colliding, but also allows users to easily remove the beer bottle by rotating it, balancing the fixing effect and the convenience of use.
[0008] Preferably, both the elastic cushioning pad and the elastic protrusion are made of EVA foam or bio-based biodegradable foam material. EVA foam or bio-based biodegradable foam material combines elastic cushioning performance with environmental protection characteristics. While meeting shock absorption requirements, it can reduce the environmental pollution problems of traditional plastic packaging, which is in line with the trend of green packaging development. The material has low density, is easy to process, and has good weather resistance and fatigue resistance. It can be reused or recycled, reducing packaging costs and resource waste.
[0009] Preferably, the elastic protrusion is hemispherical. The hemispherical structure further enhances the fixation effect on the beer bottle by optimizing the contact interface morphology: the contact area between the hemispherical curved surface and the bottom of the bottle is larger than that of a flat or angular structure, and the protrusion deforms under pressure, which can closely fit the curved surface of the bottom of the bottle, generating greater static friction and preventing the bottle from shifting due to shaking during transportation; the arc transition design of the hemispherical shape avoids stress concentration, reduces the risk of damage to the protrusion itself, and extends the service life of the cushioning structure.
[0010] Preferably, to improve the cushioning effect of the cushioning cardboard, the cushioning cardboard is honeycomb cardboard. Through its biomimetic structural design, the honeycomb cardboard significantly enhances the cushioning performance between the outer and inner boxes: the honeycomb hollow structure can progressively collapse under compression or impact, absorbing energy in stages, thus improving the cushioning effect compared to traditional flat cardboard; the honeycomb structure achieves maximum structural strength with minimal material, reducing the overall weight of the packaging box while enhancing its resistance to compression and reducing transportation energy consumption.
[0011] Preferably, to prevent collisions between adjacent beer bottles, a partition assembly is also included. This partition assembly comprises horizontal and vertical plates disposed inside the inner box, dividing the internal space of the inner box into multiple independent storage areas. The partition assembly, consisting of horizontal and vertical plates, divides the inner box into independent storage areas, achieving "dual anti-collision protection": each storage area holds only one bottle of beer, preventing contact and collision between adjacent bottles during transport vibrations, especially protecting vulnerable parts such as the bottle neck and shoulder; the cross-connection of the horizontal and vertical plates suppresses deformation of the inner box, and together with the cushioning cardboard, forms a composite protection system of "external cushioning + internal support".
[0012] Preferably, to prevent the box from becoming moldy due to moisture, ventilation holes are provided on both the horizontal and vertical panels. These ventilation holes promote air circulation inside the box, preventing mold growth caused by moisture. The ventilation holes solve the problem of mold growth in humid environments: the ventilation holes connecting the horizontal and vertical panels connect all storage areas inside the box, accelerating moisture removal, reducing local humidity, and inhibiting mold growth; during transportation, temperature changes can easily cause condensation on the bottle surface, and the ventilation holes guide the water flow to diffuse or evaporate, preventing water from soaking the cardboard or bottle label and protecting the integrity of the packaging.
[0013] The top of the cushioning cardboard has a positioning groove for inserting the horizontal and vertical plates. The positioning groove enables precise assembly of the cushioning cardboard and the partition assembly, improving the overall stability of the packaging box: the lower ends of the horizontal and vertical plates can be directly inserted into the positioning groove without additional connectors, simplifying the assembly process and improving production efficiency; the insertion and engagement of the groove and the partition can constrain the lateral displacement of the inner box, so that the cushioning force of the cushioning cardboard and the supporting force of the partition are linked, avoiding the decrease in protective performance caused by component misalignment.
[0014] This application enhances the protective performance of the beer bottle bottom from two dimensions: "flexible cushioning" and "multi-point restraint," through the combination of an elastic cushioning pad and spirally distributed elastic protrusions. The flexible material of the elastic cushioning pad can absorb vertical vibration or drop impact energy during transportation, preventing the bottle bottom from cracking due to stress concentration caused by rigid contact. The fixing groove restricts the large displacement of the beer bottle, and the spirally distributed elastic protrusions provide circumferential friction through multi-point contact, which not only prevents the bottle from shaking and colliding, but also allows users to easily remove the beer bottle by rotating it, thus balancing the fixing effect and the convenience of use.
[0015] This application uses a partition assembly composed of horizontal and vertical plates to divide the inner box into independent storage areas, achieving "dual anti-collision protection": each storage area can only hold one bottle of beer, avoiding contact and collision between adjacent bottles during transportation vibration, especially protecting vulnerable parts such as the neck and shoulder of the bottle; the cross connection of the horizontal and vertical plates can suppress the deformation of the inner box, and together with the cushioning cardboard, it forms a composite protection system of "external cushioning + internal support".
[0016] This application utilizes ventilation holes to promote air circulation within the inner box, preventing mold growth due to moisture. The ventilation holes solve the problem of mold growth in humid environments: the holes connecting the horizontal and vertical panels link different storage areas inside the box, accelerating moisture removal, reducing local humidity, and inhibiting mold growth; during transportation, temperature changes can cause condensation on the bottle surface, and the ventilation holes guide the water flow to diffuse or evaporate, preventing water from soaking the cardboard or bottle label and protecting the integrity of the packaging.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0023] Example 1
[0024] This embodiment provides a beer packaging box, such as Figure 1-3As shown, the packaging box includes an outer box 1 and an inner box 2 disposed inside the outer box 1. A cushioning cardboard 3 is disposed between the outer box 1 and the inner box 2. In order to reduce the impact on the bottom of the beer bottle, an elastic cushioning pad 4 is disposed inside the inner box 2 to reduce the impact on the bottom of the beer bottle. The top of the elastic cushioning pad 4 is provided with a fixing groove 41 for the bottom of the beer bottle to be inserted. Multiple elastic protrusions 42 that abut against the beer bottle are disposed in the fixing groove 41. The multiple elastic protrusions 42 are distributed in a spiral shape in the fixing groove 41. By combining the elastic cushioning pad 4 with the spirally distributed elastic protrusions 42, the protective performance of the bottom of the beer bottle can be improved from two dimensions: "flexible cushioning" and "multi-point restraint". The flexible material of the elastic cushioning pad 4 can absorb the vertical vibration or drop impact energy during transportation, and prevent the bottle bottom from cracking due to stress concentration caused by rigid contact. The fixing groove 41 restricts the large displacement of the beer bottle, and the spirally distributed elastic protrusions 42 provide circumferential friction through multi-point contact, which not only prevents the bottle from shaking and colliding, but also allows users to easily remove the beer bottle by rotating it, thus balancing the fixing effect and the convenience of use. When the beer carton is subjected to external impact, the elastic cushioning pad 4 first absorbs energy through its own deformation, reducing the transmission of impact to the bottom of the bottle; after the bottom of the beer bottle is inserted into the fixing groove 41, the spirally distributed elastic protrusions 42 form point contact with the curved surface of the bottle bottom. The protrusions are squeezed and undergo elastic deformation, generating a frictional force opposite to the direction of bottle movement, thus constraining the lateral displacement of the bottle; at the same time, the spiral arrangement structure allows the tangential component of the force of the protrusions to guide the bottle to smoothly detach from the fixing groove 41 when the bottle is rotated, avoiding the jamming problem of traditional rigid grooves.
[0025] Both the elastic cushioning pad 4 and the elastic protrusions 42 are made of EVA foam or bio-based biodegradable foam materials. EVA foam or bio-based biodegradable foam materials combine elastic cushioning performance with environmentally friendly characteristics. While meeting shock absorption requirements, they can reduce the environmental pollution problems of traditional plastic packaging, aligning with the trend of green packaging development. The materials have low density, are easy to process, and possess good weather resistance and fatigue resistance. They can be reused or recycled, reducing packaging costs and resource waste. When impacted, the porous structure inside EVA foam or bio-based foam materials causes the cell walls to bend, stretch, or compress, converting external mechanical energy into internal energy and achieving energy dissipation. Bio-based materials use renewable resources as raw materials and form an elastic three-dimensional network structure through a foaming process. The flexibility of its molecular chains allows it to recover its original shape after multiple impacts, maintaining cushioning performance. Simultaneously, the biodegradable components decompose naturally through microorganisms after disposal, reducing white pollution.
[0026] The elastic protrusion 42 is hemispherical. The hemispherical structure further enhances the fixation of the beer bottle by optimizing the contact interface morphology: the contact area between the hemispherical curved surface and the bottle bottom is larger than that of a flat or angular structure, and the protrusion deforms under pressure, tightly conforming to the curved surface of the bottle bottom, generating greater static friction and preventing the bottle from shifting due to shaking during transportation; the hemispherical arc transition design avoids stress concentration, reduces the risk of breakage of the protrusion itself, and extends the service life of the cushioning structure. When the beer bottle is inserted into the fixing groove 41, the hemispherical elastic protrusion 42 undergoes radial compression under the pressure of the bottle bottom, forming a surface contact between the spherical surface and the bottle bottom. The intermolecular forces of the material in the contact area and the elastic recovery force generated by deformation together constitute the frictional force; compared to a planar protrusion, the isotropic symmetry of the hemispherical shape provides balanced constraint resistance in both lateral and longitudinal vibrations, and the curvature of the spherical surface guides the bottle to slide along the tangential direction, adapting to the operation logic of rotational loading and unloading.
[0027] To improve the cushioning effect of the cushioning cardboard 3: the cushioning cardboard 3 is a honeycomb cardboard. Through biomimetic structural design, the honeycomb cardboard significantly enhances the cushioning performance between the outer box 1 and the inner box 2: the honeycomb hollow structure can progressively collapse under compression or impact, absorbing energy in stages, thus improving the cushioning effect compared to traditional flat cardboard; the honeycomb structure achieves maximum structural strength with minimal material, reducing the overall weight of the packaging box while enhancing its compression resistance and reducing transportation energy consumption. The honeycomb core layer of the cushioning cardboard 3 is composed of multiple layers of paper or plastic sheets bonded into a regular hexagonal columnar structure. When the outer box 1 is subjected to external pressure, the honeycomb core columns bear the load in the vertical direction, and the column walls absorb energy through bending or crushing deformation; the horizontal impact force is transmitted and dispersed throughout the cushioning layer through the in-plane stiffness of the honeycomb structure, avoiding local overload; this "three-dimensional force transmission + progressive deformation" mechanism effectively protects the inner box 2 and the beer bottle under conditions such as drops and compression.
[0028] Example 2
[0029] Unlike Embodiment 1, to prevent collisions between adjacent beer bottles, a partition assembly 5 is also included. The partition assembly 5 includes a horizontal plate 51 and a vertical plate 52 disposed inside the inner box 2. The horizontal plate 51 and the vertical plate 52 divide the internal space of the inner box 2 into multiple independent storage areas 53. The partition assembly 5, composed of the horizontal plate 51 and the vertical plate 52, divides the inner box 2 into independent storage areas 53, achieving "dual anti-collision protection": each storage area 53 can only hold one bottle of beer, avoiding contact and collision between adjacent bottles during transportation vibrations, especially protecting vulnerable parts such as the neck and shoulder of the bottle; the horizontal plate 51 and the vertical plate 52 are cross-connected, which can suppress the deformation of the inner box 2, and together with the cushioning cardboard 3, form a composite protection system of "external cushioning + internal support". The partition assembly 5 constructs a grid-like support structure inside the inner box 2 through the vertical insertion of the horizontal plate 51 and the vertical plate 52, and each storage area 53 becomes an independent rigid unit. When the packaging box is subjected to lateral or longitudinal impact, the partition can disperse the impact force to the four walls of the inner box 2 to avoid excessive force on a single bottle. At the same time, the independent space restricts the displacement range of the beer bottle. Even if vibration occurs, the bottle will only contact the elastic buffer pad 4 and the partition, rather than directly impacting adjacent bottles, thus eliminating the risk of collision damage from the source.
[0030] To prevent mold growth on the box due to moisture, ventilation holes 54 are provided on both the horizontal plate 51 and the vertical plate 52. These ventilation holes 54 promote air circulation inside the inner box 2, preventing mold growth. The ventilation holes 54 also solve the problem of mold growth in humid environments: the ventilation holes 54, connecting the horizontal plate 51 and the vertical plate 52, connect all storage areas 53 inside the inner box 2, accelerating moisture removal, reducing local humidity, and inhibiting mold growth; during transportation, temperature changes can easily cause condensation on the bottle surface, and the ventilation holes 54 guide the water flow to diffuse or evaporate, preventing water from soaking the cardboard or bottle label and protecting the integrity of the packaging. The air inside the inner box 2 forms a convection channel through the ventilation hole 54. Dry air from the outside can enter the storage area 53 through the gap between the outer box 1 and the inner box 2, the pores of the cushioning cardboard 3, and the ventilation hole 54, while humid air is discharged through the reverse path. When condensation occurs on the surface of the beer bottle due to temperature difference, the water droplets flow down the bottle wall. Some of them drip down to the bottom of the inner box 2 through the ventilation hole 54, and some evaporate through air flow, thereby maintaining a relatively dry environment inside the inner box 2 and destroying the humidity conditions for mold growth.
[0031] The top of the cushioning cardboard 3 is provided with a positioning groove 43 for the horizontal plate 51 and the vertical plate 52 to be inserted. The positioning groove 43 enables the precise assembly of the cushioning cardboard 3 and the partition assembly 5, improving the overall stability of the packaging box: the lower ends of the horizontal plate 51 and the vertical plate 52 can be directly inserted into the positioning groove 43 without the need for additional connecting parts, simplifying the assembly process and improving production efficiency; the insertion and cooperation between the groove and the partition can constrain the lateral displacement of the inner box 2, so that the cushioning force of the cushioning cardboard 3 and the supporting force of the partition are linked, avoiding the decrease in protective performance caused by component misalignment. The positioning groove 43 on the top of the cushioning cardboard 3 is designed according to the cross-sectional dimensions of the horizontal plate 51 and the vertical plate 52 to form a "convex-concave fit" structure. During assembly, the lower end of the partition assembly 5 is inserted into the groove and fixed by the elastic clamping force of the cardboard to form a mechanical connection. During transportation, when the inner box 2 is subjected to lateral impact, the positioning groove 43 can transfer the impact force to the cushioning cardboard 3 through friction and the shear resistance of the insertion structure, so as to prevent the partition assembly 5 from tilting or shifting, and ensure that all protective components work together to maintain stable protective performance.
[0032] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.
[0033] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
