Description

Technical Field

[0001] The utility model relates to the technical field of honeycomb cartons, in particular to a deformation-resistant honeycomb carton structure. Background Art

[0002] Honeycomb paperboard is made of honeycomb paperboard as the main material through stamping, cutting, pasting and other processes. It is light in material, heavy in load-bearing capacity, excellent in cushioning performance, environmentally friendly and energy-saving.

[0003] At present, honeycomb cartons are widely used in the express delivery industry. Generally, the items are placed in the honeycomb cartons, which are then sealed with tapes. Then, a large number of honeycomb cartons are stacked in the cargo compartment for transportation. The transportation journey is divided into long-distance transportation and short-distance transportation. In short-distance transportation, the honeycomb cartons at the bottom need to withstand pressure for a shorter time, and the sides of the honeycomb cartons are not easy to deform. Compared with short-distance transportation, the honeycomb cartons at the bottom need to withstand pressure for a longer time in long-distance transportation, and the sides of the honeycomb cartons are prone to deformation to varying degrees, thereby causing varying degrees of squeezing of the items in the honeycomb cartons, which can easily damage the items.

[0004] In order to solve the above problems, the present application proposes a deformation-resistant honeycomb carton structure. Utility Model Content

[0005] The utility model aims at the technical problems existing in the prior art and provides a honeycomb paper box structure which is resistant to deformation.

[0006] The utility model solves the above technical problems with the following technical solutions: a deformation-resistant honeycomb paper box structure, comprising an inner paperboard layer, one side of which is sequentially provided with a honeycomb layer, an outer paperboard layer, a waterproof layer, a buffer layer, and an anti-scratch layer;

[0007] The honeycomb layer package is specifically a honeycomb paperboard, and an elastic roll is arranged in the honeycomb layer, and the elastic roll is specifically an elastic paper;

[0008] Both sides of the inner circle of the elastic roll are provided with adhesive, and the elastic roll is respectively adhered to the outer paperboard layer and the inner paperboard layer through the adhesive on both sides, so as to fix the inner circle of the elastic roll.

[0009] The outer paperboard layer and the inner paperboard layer are specifically corrugated paper layers, and the outer paperboard layer and the inner paperboard layer are provided as the base material of the carton;

[0010] The waterproof layer is specifically an acrylic waterproof coating layer, which is used to prevent the outer paperboard layer, the honeycomb layer, the inner paperboard layer and the elastic roll from being soaked by water as much as possible;

[0011] The buffer layer is specifically a polyurethane foam layer, which is used to reduce the impact force on the carton when loading and unloading goods.

[0012] The anti-scratch layer is specifically an anti-scratch paint layer, and the anti-scratch layer is set as an anti-scratch paint layer to prevent the carton from being scratched during transportation as much as possible.

[0013] The beneficial effects of the utility model are:

[0014] By rolling the elastic paper as many times as possible and inserting the elastic roll into the honeycomb layer, the elastic roll is pre-set with an outward force, so that the elastic roll has an outward prestressed force to cope with the pressure from top to bottom, thereby enhancing the compression resistance of the honeycomb paperboard, thereby achieving the effect of improving the anti-deformation ability of the honeycomb carton, and avoiding the deformation of the honeycomb carton due to long-term pressure during long-distance transportation, which is helpful to protect the items in the honeycomb carton;

[0015] The waterproof layer with acrylic waterproof coating can prevent the carton from being soaked by rain and splashing water during transportation, and ensure the carton's ability to resist deformation.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0022] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise clearly and specifically defined.

[0023] In the description of the present application, the term "for example" is used to mean "used as an example, illustration or description". Any embodiment described as "for example" in the present application is not necessarily to be construed as being more preferred or advantageous than other embodiments. In order to enable any technician in the field to implement and use the utility model, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the utility model can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the utility model obscure. Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0024] Reference Figure 1-2 , a deformation-resistant honeycomb carton structure, comprising an inner cardboard layer 8, a honeycomb layer 2, an outer cardboard layer 1, a waterproof layer 3, a buffer layer 4, and an anti-scratch layer 5 are sequentially arranged on one side of the inner cardboard layer 8, the honeycomb layer 2 is specifically a honeycomb cardboard, and an elastic roll 6 is arranged inside the honeycomb layer 2, and the elastic roll 6 is specifically an elastic paper. The elastic paper can be deformed when subjected to an external force, but can quickly return to its original state after the external force disappears. Common scenarios are: items that are frequently folded or unfolded, such as paper airplanes and paper crafts. In the present technical solution, the elastic paper needs to be consistent with the thickness of the honeycomb layer 2, and then the elastic paper is curled as many times as possible, and then the elastic roll 6 is inserted into the honeycomb layer 2. At this time, the elastic roll 6 is pre-set with an outward force, so that the elastic roll 6 has an outward prestressed force to cope with the pressure from top to bottom, thereby enhancing the compressive strength of the honeycomb cardboard, thereby achieving the effect of improving the anti-deformation ability of the honeycomb carton, and trying to avoid the deformation of the honeycomb carton under long-term pressure during long-distance transportation, which is helpful to protect the items in the honeycomb carton;

[0025] It should be added that the elastic roll 6 can also be made of kraft paper, which has good toughness and life. In addition, if cost is not considered, materials other than paper can be used, such as plastic and elastic steel. However, it should be noted that when using such materials, the thickness of the honeycomb paperboard must be considered to avoid the sharp outer ring of such materials from puncturing the honeycomb paperboard.

[0026] Reference Figure 2and Figure 3 , adhesive 7 is provided on both sides of the inner circle of the elastic roll 6, and the elastic roll 6 is respectively adhered to the outer paperboard layer 1 and the inner paperboard layer 8 through the adhesive 7 on both sides. The adhesive 7 specifically adopts a rubber-type adhesive, which is mainly made of synthetic rubber or natural rubber, has good adhesion and is resistant to aging. The inner circle of the elastic roll 6 is fixed to the outer paperboard layer 1 and the inner paperboard layer 8 by the adhesive 7, which helps to improve the stability of the elastic roll 6.

[0027] Reference Figure 1 The outer paperboard layer 1 and the inner paperboard layer 8 are specifically corrugated paper layers, and the specific material used is corrugated paper. Using corrugated paper as the basis and main material of the carton makes the carton have good properties of corrugated paper, such as:

[0028] Good cushioning performance: Due to the special structure of corrugated cardboard, 60% to 70% of the volume of the cardboard structure is empty, so it has good shock absorption performance. This feature enables the corrugated box to effectively prevent the packaged items from collision and impact, thereby protecting the safety of the internal items;

[0029] Light and strong: Corrugated cardboard is a hollow structure, which uses less material to form a more rigid box, which makes the corrugated box more stable among similar boxes. Compared with wooden boxes of the same volume, the weight of the corrugated box is only about half of that of the wooden box, so it is lighter.

[0030] Reference Figure 1 The waterproof layer 3 is specifically an acrylic waterproof coating layer, and the specific material used is acrylic waterproof coating. Acrylic waterproof coating is a water-soluble waterproof material, which has elasticity and ductility after conjunctiva, and is a very dense waterproof material;

[0031] When in use, you can add water to dilute it appropriately, and then apply the acrylic waterproof coating on the corrugated paper of the outer cardboard layer 1, so as to avoid the carton from being soaked by rain and splashing water during transportation, which helps to protect the outer cardboard layer, honeycomb layer, inner cardboard layer and elastic roll, and achieves the effect of ensuring the carton's anti-deformation ability as much as possible.

[0032] It should be noted that other waterproof coatings may also be used for the waterproof layer 3, including but not limited to polyurethane coatings. It should be noted that the selected waterproof coatings need to have a short drying time to avoid damage to the corrugated cardboard due to the long drying and film formation time of the waterproof coating.

[0033] Reference Figure 1, the buffer layer 4 is specifically a polyurethane foam layer, and the material used is polyurethane foam. It is a polymer formed by mixing with the help of various additives such as foaming agents, catalysts, and flame retardants, and then foaming on-site by high-pressure spraying through special equipment, so that the foam adheres to the outside of the waterproof layer 3, which helps to improve the impact resistance of the carton. The usage scenario can be: when the carton loaded with items is being carried, it will experience multiple pick-ups and placements, and during this process, the carton is likely to collide with other objects. At this time, the buffer layer 4 plays a buffering role.

[0034] Refer to Figure 1 , the scratch-resistant layer 5 is specifically a scratch-resistant paint layer, and the material used is scratch-resistant paint, which can provide strong scratch resistance and help protect the buffer layer 4 and the waterproof layer 3 of the carton from being scratched by other objects during handling and placement, and try to avoid reducing the anti-deformation ability of the carton.

[0035] Working principle:

[0036] For the honeycomb carton structure with anti-deformation function, by curling the elastic paper as many turns as possible, and then inserting the elastic coil 6 into the honeycomb layer 2. At this time, the elastic coil 6 is preset with an outward force, so that the elastic coil 6 has an outward prestress to cope with the downward pressure, thereby enhancing the compressive resistance of the honeycomb cardboard, and thus achieving the effect of improving the anti-deformation ability of the honeycomb carton, and trying to avoid the deformation of the honeycomb carton due to long-term compression during long-distance transportation, which helps to protect the items in the honeycomb carton.

[0037] For the honeycomb carton structure with anti-deformation function, the waterproof layer 3 with acrylic waterproof coating is used to avoid the water such as rainwater and splashed water during handling from wetting the carton, which helps to protect the outer cardboard layer, honeycomb layer, inner cardboard layer and elastic coil, and achieves the effect of ensuring the anti-deformation ability of the carton as much as possible. The buffer layer 4 with polyurethane foam improves the impact resistance of the carton, and the scratch-resistant layer 5 with scratch-resistant paint improves the strong scratch resistance.

[0038] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications once they know the basic creative concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0039] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
