Detailed Description
In order to make the technical solutions in the present invention better understood by those skilled in the art, the technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the accompanying drawings:
the utility model provides a tear corrugated container board, as shown in figure 1, including cardboard body 1, have the line ball 2 that can buckle it on the cardboard body 1, the indentation of this line ball 2 is accomplished through line ball 2 wheel, in order to be used for forming the corner of carton, cardboard body 1 through line ball 2 not only can improve the efficiency of preparation carton, moreover because the indentation atress of line ball 2 is even, form through the extrusion, so this position is for other positions, the atress intensity will be some more high, certain external force can be born to the part, and can not break.
As shown in fig. 2, the paperboard body 1 sequentially includes a surface paper layer 11, a first corrugated paper layer 12, a core paper layer 13, a second corrugated paper layer 14, and a bottom paper layer 15 from top to bottom, the paperboard body 1 further includes a compression-resistant strip 16, the compression-resistant strip 16 is disposed between the first corrugated paper layer 12 and the core paper layer 13, and the compression-resistant strip 16 overlaps the pressing line 2.
Although the 2 positions of line ball of cardboard body 1 have certain intensity after the pressfitting, make the carton, and when being used for the great object of vanning, the 2 positions of line ball can be tightened out darker seal of a government organization in transit by the packing area and then damaged or receive the striking back and lead to the damage of line ball 2 position, to this be provided with the resistance to compression layering 16 between first corrugated paper layer 12 and core paper layer 13, as shown in figure 1, and with the line ball 2 coincidence setting on 16 and the cardboard body 1 of resistance to compression layering, thereby the effectual compressive strength who improves 2 positions of line ball makes this position difficult fracture.
After the carton is manufactured by the carton body 1, the position where the packing belt is fixed on the carton is difficult to determine, and for the position, the length of the compression-resistant pressing strip 16 is consistent with that of the carton body 1, so that the processing is convenient, and the situation that the packing belt on the carton does not act on the compression-resistant pressing strip 16 to cause that the corresponding compression-resistant technical effect cannot be achieved can be avoided.
Preferably, as shown in fig. 2 and 3, the compression-resistant bead 16 is made of a bendable material, side protection plates 17 are respectively arranged on two sides of the compression-resistant bead 16, and the compression-resistant bead 16 and the side protection plates 17 have the same width as the pressing line 2.
After cardboard body 1 made the carton, although line ball 2 position can bear the biggest external force in packing area, but line ball 2's both sides also can receive stronger external force, are provided with side protection board 17 in compression moulding 16's both sides to this, buckle into 90 backs at line ball 2 of carton body, compression moulding 16 and two side protection boards 17 can buckle and form a structure similar to cornerite, can effectually play the effect of protection to the carton through this structure.
Preferably, as shown in fig. 4, the compression beads 16 comprise a foldable metal mesh layer 161 and a protective layer 162 covering the metal mesh layer 161, wherein the protective layer 162 is woven from high-strength synthetic fibers.
The metal mesh layer 161 may be made of a wire mesh which is easily bent in the width direction and is not easily bent in the length direction, and a protective layer woven from high-strength synthetic fibers is bonded to the surface of the metal mesh layer 161 to improve the axial bending resistance of the pressed line 2 of the paperboard body 1 to a certain extent and to further improve the strength and protect the metal mesh layer 161.
Preferably, as shown in fig. 1, in order to make the paperboard body 1 have moisture-proof and antistatic effects, an antistatic plastic film 18 is attached to the outer surfaces of the face paper layer 11 and the base paper layer 15.
The above embodiments are only preferred embodiments of the present invention, not all embodiments, and other embodiments obtained based on the above embodiments by those skilled in the art without any creative work shall fall within the protection scope of the present invention, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
