Description

Corrugated cardboard boxes with additional layers in key parts

technical field

The utility model relates to the field of packaging, in particular to a corrugated box.

Background technique

Corrugated box is a widely used packaging product, especially in the fast moving consumer goods industry, the usage is huge. At present, the corrugated boxes on the market are all made of corrugated cardboard through one or several processes such as printing, slotting, die-cutting, nailing, and gluing. There are many types of corrugated boxes, but at present No matter what kind of box-type cartons are on the market, the number of material layers of each part of the same piece of corrugated cardboard is the same. In the use of such cartons, often some parts have insufficient physical properties or some Some physical properties of parts are excessive, resulting in insufficient protection of the packaged items or waste of materials used in cartons. Especially the standard slotted carton, the international standard 0201 box type, this kind of carton is made of a single piece of corrugated cardboard. Because the upper and lower sides of the screen are composed of four rocker covers and four bottom covers, many parts overlap, which leads to waste of the upper and lower sides due to excessive use of materials. Conversely, in some cases, the upper and lower sides While just meeting the performance requirements, the four sides are only composed of a single piece of corrugated cardboard, so the physical properties are not enough, such as the data of compression resistance and burst resistance are not up to the standard, resulting in insufficient protection for the packaged items.

Based on the above deficiencies, the inventor proposes an innovative corrugated box to solve the existing deficiencies.

Contents of the invention

In order to solve the above-mentioned shortcomings of the existing corrugated boxes, the utility model proposes a corrugated box with layers added to key parts. This design ensures the compressive strength and bursting strength of the carton, and saves materials in the secondary parts of the carton, that is, The cost is reduced, and the convenience of use is also guaranteed because no separate parts are added during the use of this carton.

The technical scheme that the utility model adopts is as follows:

The corrugated cardboard box with layers added to the key parts is characterized in that: the layer added is to increase the number of layers in a certain part of the corrugated cardboard used in the corrugated cardboard that needs to be strengthened, thereby enhancing the physical properties of the key parts. It is glued and integrated with the original whole piece of cardboard, thus ensuring the convenience of use of this new carton.

The added layer is any corrugated structure composed of a layer of corrugated paper and a layer of paper. In order to pursue higher performance, there is another case for the added layer, which can be added on the basis of the original layer. Corrugated paper and a layer of paper form any type of corrugated structure.

There are two situations for the key parts, one is to add layers on the four sides of the carton, and the other is to add layers to the four sides of the carton and the bottom surface of the carton at the same time.

The layering can be added on the basis of the original corrugated cardboard of any shape and any number of layers.

Beneficial effects of the utility model

The compressive and bursting strength of the four sides of the carton can be increased independently, and the supporting strength of the bottom of the carton can be increased at the same time, so as to better protect the products in the carton. It can reduce the paper material used in the whole carton while ensuring the compressive and bursting strength of the four sides of the carton, thereby reducing the packaging cost.

detailed description

As shown in Figure 1 and Figure 3, a corrugated box with layers added to key parts, it is a corrugated box with layers added to key parts on four sides (2 in Figure 1), and the four sides are the four supports of the carton On the surface, a layer of corrugated paper and a layer of paper (4 and 5 in Figure 2) are added on the basis of the original cardboard corresponding to the four sides, that is, a single corrugated structure (1 in Figure 3) is laminated. , The laminated cardboard and carton are integrated, so the convenience of using the carton is guaranteed. The cardboard material on the four sides of the carton with layers added to this key part has two more layers of paper (4 and 5 in Figure 4) than its top and bottom surfaces, thereby increasing the compressive strength and strength of these important parts. Bursting strength, the data in this aspect is equivalent to that of double corrugated cartons made of five-layer paper, so it plays a role in strengthening the protection of packaging in practical applications. Conversely, if the compressive and bursting strength of these important parts of the carton can only be met with a double corrugated box made of five-layer paper, the top of the corrugated box with layers added to this key part The top and bottom of the carton have two layers of paper less than the four sides, so the paper materials on the top and bottom of the carton can be saved while meeting the performance requirements of these key parts such as compression resistance and burst resistance. For example, if the single-box packaging is not very heavy, but it needs to be stacked and arranged in multiple layers on the pallet, it is most suitable in this case, because this situation has higher requirements on the compressive and bursting strength of the four sides of the carton. High, but the requirements for the top and bottom of the carton are not high. The stacking force is on the four sides of the carton. The requirements for breaking resistance are basically on the four sides. The bottom of the carton only bears the gravity of the packaging in a single box. The top surface of the carton is not stressed, and the materials on the top and bottom of this box-type carton overlap after the lid is closed, so the bottom and top materials do not need to have the same number of layers as the four sides to meet the performance.

According to the above embodiment, another embodiment is developed, as shown in Fig. 5 and Fig. 6, a kind of corrugated cardboard box with layers added on the key parts, which is added on the four sides and the bottom surface (1 in Fig. 5) as the key parts The four sides are the four supporting surfaces of the carton, and the bottom surface refers to the four bottom flaps. A Single corrugated structure, the laminated cardboard and carton are integrated, so the convenience of using the carton is guaranteed. The cardboard material on the four sides and the bottom of the corrugated box with layers added to this key part has two more layers of paper than its top material (4 and 5 in Figure 6), thereby increasing the compressive strength of these important parts Compared with the bursting strength, the data in this aspect is equivalent to that of double corrugated cartons made of five-layer paper, so it plays a role in strengthening the protection of the packaging in practical applications. Conversely, if the compressive and bursting strength of these important parts of the carton originally requires a double corrugated carton with five layers of paper to meet the requirements, the top surface of the corrugated carton with layers added to this key part There are two layers of paper less than the four sides and the bottom surface, so it can save the material on the top surface while meeting the performance requirements of compression resistance and burst resistance. For example, the single-box packaging is relatively heavy, but it needs to be stacked and arranged in multiple layers on the pallet. In this case, it is most suitable, because this situation requires the compressive and bursting strength of the four supporting surfaces of the carton. Higher, the bottom surface of the carton needs to support the heavy packaging of the single box when handling a single box, so the requirements for the supporting force of the bottom surface of the carton are relatively high, but the requirements for the top surface of the carton are not high, and the stacking force is all in the carton On the four support surfaces, the burst resistance requirements are basically on the four support surfaces, and the top surface of the carton is not stressed.

In addition, according to the above method of adding layers, it can be analogized to add layers on the basis of double corrugated cardboard with five layers of paper.

The above is only a description of the preferred implementation of the present utility model, and does not limit the technical solution of the present utility model thereto. Those skilled in the art can obtain the changed result for various reasonable transformations on the basis of the disclosure content of the specification. Technical solutions, as long as they do not deviate from the spirit of the utility model, various technical solutions after changes are within the scope of protection of the utility model.
