Corrugated cardboard facilitating stacking

Abstract

This utility model discloses a corrugated cardboard that is easy to stack, comprising a face paper layer, a corrugated core paper layer, and a bottom paper layer. A set of transverse reinforcing ribs is fixedly embedded inside the face paper layer and the corrugated core paper layer, and a set of longitudinal reinforcing ribs is fixedly embedded inside the corrugated core paper layer. A cross-shaped protrusion is connected to the upper surface of the face paper layer, and a cross-shaped groove adapted to the cross-shaped protrusion is formed on the bottom surface of the bottom paper layer. This device, through the longitudinal and transverse reinforcing ribs, can form a reinforcing rib grid, effectively increasing the load-bearing capacity of the face paper layer, corrugated core paper layer, and bottom paper layer, thereby increasing the overall stability of the corrugated cardboard and facilitating stable stacking. Furthermore, the cross-shaped protrusion, cross-shaped groove, limiting plate, and U-shaped limiting groove enable the cardboard to be stacked in a collet configuration, and provide corresponding positional limiting during stacking, facilitating stable stacking and transportation of the corrugated cardboard.

Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard technology, and in particular to a corrugated cardboard that is easy to stack. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper and one layer of cardboard. It has high mechanical strength and can withstand collisions and drops during handling. It is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods. As a core material of the modern packaging industry, the stacking stability of corrugated cardboard is directly related to logistics efficiency and transportation safety.

[0003] Among them, the utility model patent with announcement number CN212477281U discloses an energy-saving and environmentally friendly corrugated cardboard that is easy to stack. However, the above patent still has some shortcomings in use. When stacking corrugated cardboard, it is not possible to effectively limit the position of the corrugated cardboard. Moreover, the internal stability of the corrugated cardboard is poor, which is not convenient for the stable stacking and transportation of corrugated cardboard. Therefore, we propose a corrugated cardboard that is easy to stack to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a corrugated cardboard that is easy to stack, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A type of corrugated cardboard that is easy to stack includes a corrugated cardboard, which includes a face paper layer, a corrugated core paper layer and a bottom paper layer. A set of transverse reinforcing ribs are fixedly embedded inside the face paper layer and the inside of the bottom paper layer. A set of longitudinal reinforcing ribs are fixedly embedded inside the corrugated core paper layer. A cross protrusion is connected to the upper surface of the face paper layer, and a cross groove that matches the cross protrusion is opened on the bottom surface of the bottom paper layer.

[0007] In a further embodiment, a logo is sprayed onto the upper surface of the face paper layer, and the logo is located at the right end of the face paper layer.

[0008] In a further embodiment, two limiting plates are connected to both the front and back of the corrugated cardboard, and each limiting plate has a U-shaped limiting groove on its upper surface.

[0009] In a further embodiment, the limiting plate is made of the same material as the corrugated cardboard.

[0010] In a further embodiment, both the transverse reinforcing ribs and the longitudinal reinforcing ribs are made of rubber.

[0011] In a further embodiment, the front side of the corrugated cardboard is provided with a set of positioning arrows, and the number of the positioning arrows in the set is at least two.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device, through its longitudinal and transverse reinforcing ribs, forms a reinforcing rib grid, effectively increasing the load-bearing capacity of the face paper layer, corrugated core paper layer, and bottom paper layer, thereby increasing the overall stability of the corrugated board and facilitating stable stacking. Furthermore, through the inclusion of cross protrusions, cross slots, limiting plates, and U-shaped limiting grooves, it enables the cardboard to be stacked in a collet configuration and provides corresponding positional limits during stacking, facilitating stable stacking and transportation of the corrugated board.

[0019] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0022] Please see Figure 1-4 In this utility model, a corrugated cardboard that is easy to stack includes a corrugated cardboard 1. The corrugated cardboard 1 includes a face paper layer 11, a corrugated core paper layer 12, and a bottom paper layer 13. A set of transverse reinforcing ribs 8 are fixedly embedded inside the face paper layer 11 and the bottom paper layer 13. A set of longitudinal reinforcing ribs 7 are fixedly embedded inside the corrugated core paper layer 12. A cross protrusion 2 is connected to the upper surface of the face paper layer 11. A cross groove 6 that matches the cross protrusion 2 is opened on the bottom surface of the bottom paper layer 13.

[0023] The upper surface of the face paper layer 11 is sprayed with a logo mark 5, which is located at the right end of the face paper layer 11. The logo mark 5 can express the trademark of the corrugated cardboard 1, which is convenient for the sale of the corrugated cardboard 1. The front and back of the corrugated cardboard 1 are connected to two limiting plates 3. Each limiting plate 3 has a U-shaped limiting groove 31 on its upper surface. The limiting plate 3 is made of the same material as the corrugated cardboard 1 and can limit and block the corrugated cardboard 1 when it is stacked, which is convenient for the stable stacking of the corrugated cardboard 1.

[0024] Both the transverse reinforcing ribs 8 and the longitudinal reinforcing ribs 7 are made of rubber, which can increase the load-bearing capacity of the corrugated cardboard 1.
