Description

  The present invention relates to a packaging material using corrugated paper, and more particularly to a packaging box which can be creased at a designed position and has a high compressive strength.

  Corrugated paper has a corrugated sheet and therefore has a buffering effect, and is widely used as a packaging container for transporting boxes, cans, cartons, containers and the like, and as a structural material for transferring heavy objects such as pallets. However, corrugated cardboard has directionality because corrugated grooves are formed in a direction transverse to the paper feeding direction.

For example, corrugated paper is also used in the packaging box of the annular fluorescent lamp shown in Patent Document 1. This conventional corrugated cardboard is composed of three sheets each having a flat sheet bonded to both outer sides of a corrugated sheet. And since it bends along the corrugated groove attached in the horizontal direction, if the folding surface hits the position of the corrugated groove, it may be bent at the position of the next corrugated peak, There was a drawback that it could not be applied exactly as designed.
JP 2002-274582 A

  If this corrugated paper can be made into two sheets in which a flat sheet is bonded to only one side of the corrugated sheet, it is preferable in terms of saving material. However, the box assembled with two sheets has a drawback that it is recessed along the step of the groove and is bent when compressed and does not have strength.

  In view of the above circumstances, a problem to be solved by the present invention is to provide a packaging box using corrugated cardboard paper having a crease as designed and having high compressive strength.

  In order to achieve the above object, the present invention is a packaging box using corrugated cardboard having corrugated sheets, wherein the corrugated grooves are formed at a bias of 45 degrees with respect to the longitudinal and lateral directions of the corrugated sheets. It constitutes a packaging box using cardboard paper cut and assembled.

  The packaging box using the corrugated cardboard of the present invention has improved machine suitability and can be creased at the position as per the design drawing.

  The packaging box using the corrugated cardboard of the present invention has increased the compressive strength of the assembly box.

  The packaging box using the corrugated cardboard of the present invention can serve as a cushioning material if two sheets of outer sheets are flat sheets and inner surfaces are corrugated sheets.

  Hereinafter, a packaging box using the corrugated cardboard of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a state in which a cover of an assembly box of an annular fluorescent lamp showing an embodiment of a packaging box using the cardboard of the present invention is opened, and FIG. 2 is a perspective view showing one side of the cardboard. FIG. 3 and FIG. 3 are development views of the corrugated cardboard.

  The ordinary corrugated cardboard is composed of three sheets having a flat sheet bonded to both sides of the corrugated sheet. It has become.

  The packaging box 4 assembled using the corrugated cardboard 1 is configured such that the outer surface O is a flat sheet 3 and the inner surface 1 is a corrugated sheet 2. Therefore, the corrugated sheet 2 comes into contact with an object to be packaged and serves as a cushioning material.

  However, the corrugated cardboard 1 of the present invention is characterized in that it is assembled by cutting the corrugated grooves 5 so as to form a bias of 45 degrees with respect to the longitudinal and lateral directions of the corrugated sheet 2.

  The packaging box 4 is formed of a single corrugated cardboard sheet that is formed in a box shape and has six sides. As shown in FIG. 3, the packaging box 4 includes a front surface portion 11 and a back surface portion 12. Between the two, a rear surface portion 13 is provided via folds 30a and 30b.

  Side surfaces 14 and 15 are connected to the front surface portion 11 through fold lines 31a and 31b, and side surface portions 16 and 17 are connected to the back surface portion 11 through fold lines 32a and 32b. The lid surface part 18 and the folding part 19 are connected via 33b. Further, the ear portion 20 is connected to the side surface portion 16 through a fold line 34a, and the ear portion 21 is connected to the side surface portion 17 through a fold line 34b.

  A concave portion 22 is provided on the side edge of the surface portion 11, and a window portion 23 is provided on the lid surface portion 18. And since the corrugated groove 5 of corrugated cardboard having corrugated sheets is cut so as to form a bias of 45 degrees with respect to the longitudinal and lateral directions of the corrugated sheet 2, the corrugated grooves 5 of corrugated paper have a 45 degree bias. It is provided.

  In order to assemble the packaging box from the single cardboard sheet, the side surface portions 14 and 15 are folded from the surface portion 11 through the fold lines 31a and 31b, the rear surface portion 13 is folded through the fold lines 30a and 30b, and the fold line is formed. The side surface parts 16 and 17 are folded up via 32a and 32b.

  Next, the side surface portions 14 and 15 are placed outside, the side surface portions 16 and 17 are polymerized, and the side surface portions 14 and 15 are adhered by being glued to the outer surfaces of the side surface portions 16 and 17. Next, the ear part 20 is folded inward through the fold line 34a, the ear part 21 is also folded inward through the fold line 34b, the lid surface part 18 is folded inward through the fold line 33a, and the folded part 19 is surfaced through the fold line 33b. The packaging box 4 formed into a box shape having six sides is assembled by folding inside the part 1.

  The packaging box using the corrugated paper of the present invention is a box, can, carton, container, etc. by corrugating corrugated sheet of paper and cutting it so as to be formed into a bias of 45 degrees with respect to the vertical and horizontal directions. The present invention can be widely used for packaging containers for transportation and packaging materials ranging from reinforced corrugated paper in which two to three layers of corrugated paper are stacked.

It is a perspective view which shows the state which opened the cover of the assembly packaging box of the annular fluorescent lamp which shows one Example of the packaging material using the cardboard paper of this invention. It is a perspective view which shows one surface of the cardboard paper. It is an expanded view of the corrugated cardboard.
