Problems solved by technology

[0011] The existing rocker cover, bottom cover, and body plate have the same thickness and structure. When only tiles are considered to increase the compressive strength of the body plate, the material of the rocker cover and bottom cover will increase and the cost will increase.

Embodiment 1

[0118]Example 1 Overview of the base plate 1 and the reinforcing plate 2: the base plate 1 is a double-layer or four-layer corrugated cardboard, the reinforcing plate 2 is a three-layer, five-layer or seven-layer corrugated cardboard, and the reinforcing plate 2 is bonded to on the corrugated paper layer of the middle board 12 , or: the reinforcing board 2 is glued on the corrugated paper layers of both the middle board 12 and the lower board 13 . It can be seen from the above that the corrugated surface of the double-layer or four-layer corrugated cardboard is exposed, and its bonding surface with the reinforcing plate 2 is the corrugated paper surface, and the single-number corrugated cardboard of the three-layer, five-layer or seven-layer corrugated cardboard has two flat paper surfaces (also known as Container board), one of its two flat paper faces is bonded to the corrugated paper of double- or four-ply corrugated board.

Embodiment 2

[0127] Embodiment 2 Substrate 1 and reinforcement board 2 Overview: the substrate 1 is a double-layer or four-layer corrugated cardboard, the reinforcement board 2 is a double-layer or four-layer corrugated board, and the reinforcement board 2 is bonded to the on the corrugated paper layer of the middle board 12, or, the reinforcing board 2 is glued on the corrugated paper layers of both the middle board 12 and the lower board 13 through its face paper. The corrugated paper layers bonded to both the middle board 12 and the lower board 13 have the following relationship: the number of layers of the corrugated board of the reinforced board bonded to the middle board 12 is greater than or equal to the number of layers of corrugated boards bonded to the lower board 13 The number of layers of corrugated cardboard for the board. For example: taking the specific layer structure of the reinforcing plate and the base plate as an example, it is described as: the corrugated cardboard of ...

Embodiment 3

[0137] The technical solution of this patent is relatively simple and easy to understand, wherein the drawings are based on an odd number of three-layer substrates and are connected with reinforcing plates. Figure 1-Figure 10 It shows the embodiment of bonding different reinforcing boards at different positions of the three-layer substrate, and also includes the setting of the covering paper.

[0138] Example 3 Overview of substrate 1 and reinforcement board 2: the substrate 1 is three-layer or five-layer or seven-layer corrugated cardboard, the reinforcement board 2 is three-layer, five-layer or seven-layer corrugated board, and the reinforcement board 2 is glued on the middle board 12, or the reinforcing board 2 is bonded on both the middle board 12 and the lower board 13.

[0139] The corrugated paper layers bonded to both the middle board 12 and the lower board 13 have the following relationship: the number of layers of the corrugated board of the reinforced board bonded ...

Abstract

The invention belongs to the technical field of packaging articles, and particularly relates to a paperboard and a carton made of the same. The paperboard comprises a base board and a reinforcing board, the base board and the reinforcing board are multi-layer corrugated boards, the corrugated direction of the base board is consistent with that of the reinforcing board, the length of the base board is larger than that of the reinforcing board in the corrugated direction, the base board comprises an upper board, a middle board and a lower board which are integrally connected, the reinforcing board is arranged on the middle board, or the reinforcing board is arranged on the middle board and the lower board. A top cover, a body board and a bottom cover of the carton are formed by the two or three areas with different thicknesses of the paperboard respectively, the thickness of the top cover of the carton made of the paperboard is smaller than that of the body board of the carton made of the paperboard, and paper is saved and cost is reduced while compressive strength of a packaging box is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of packaging articles, and in particular relates to a cardboard and a carton made of it. Background technique [0002] Corrugated cardboard is made by bonding face paper, inner paper, middle paper and corrugated paper processed into corrugated corrugated. [0003] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper interlayer (commonly known as "pit sheet", "corrugated paper", "corrugated core paper", "corrugated core", "corrugated base paper") and a layer Cardboard (also known as "boxboard", "boxboard") has high mechanical strength and can withstand collisions and falls during handling. The actual performance of corrugated cardboard depends on three factors: corrugated paper and cardboard The characteristics and the structure of the carton itself. [0004] In 1920, double corrugated cardboard came out, and its use expanded rapidly. During Wor...
