By this bonding, the vertically standing state of the lid side plate 26, the lid side plate 27, and the lid upper plate 25 is maintained. In this way, the lid 2 shown in FIG. 3 is assembled.

"How to open and close the lid"
A method for opening and closing the lid 2 of the paper packaging container 1 will be described. 4 to 6 are explanatory diagrams for explaining a method for opening and closing the lid portion 2 of the paper packaging container 1. Here, FIG. 4 is an arrow view in the X direction in FIGS. 1 and 3.

  When the paper packaging container 1 is covered with the lid 2, the crease c is valley-folded so that the R shape 34 of the lid side plate 27 is lowered from the state of FIG. 3 where the lid side plate 14 stands upright. By lowering the R shape 34 and increasing the degree of valley folding of the crease c, the R shape 34 comes into contact with the protruding portion 22 formed on the container upper surface plate 18 of the container portion 4.

  Further, when the lid side plate 27 is pressed by pushing down the protruding portion 22, the tip of the protruding portion 22 is bent toward the bottom plate 12 as shown in FIG. 5. The pushed and bent protrusion 22 slides on the R shape 34 and further lowers the lid side plate 27. When the notch 31 is further lowered and reaches the position of the protrusion 22, the protrusion 22 is released from being pushed into the notch 31 and inserted (see the solid line in FIG. 4). The state indicated by

  Similarly, when the lid side plate 26 that has been lowered on the facing side presses the protruding portion 21, the protruding portion 21 slides while the R shape 32 is pushed and bent in the state of FIG. 5. When the notch 30 is further lowered and reaches the position of the protrusion 21, the protrusion 21 is inserted into the notch 30. Thus, the fitting structure of the protrusion and the notch shown in FIG. 4 is formed, and the paper packaging container 1 of FIG. 1 is covered. Note that, when descending, the bottom side plate 11 and the bottom side plate 11 are lowered so as to cover the container portion 4 so that the inner side surfaces of the lid side plate 26 and the lid side plate 27 overlap the outer peripheral surface.

  Next, when the lid 2 is opened and the lid of the paper packaging container 1 is opened, the R shape 34 of the lid side plate 27 from the state of FIG. The crease c is pushed up so as to raise it. When raised as shown in FIG. 6, the fitting structure between the projecting portion and the notch is released, and is discharged from the notch 31. That is, as shown in FIG. 6, the tip of the protruding portion 22 discharged is pushed and bent toward the container upper surface plate 18. The pushed and bent protrusion 22 slides on the R shape 34 until the container side plate 27 does not come into contact. After the container side plate 27 stops contacting, the pushed and bent state of the protruding portion 22 is released. Furthermore, the container side plate 27 can be raised to the state shown in FIG. 3 in which the lid 2 is upright, and the lid can be opened.

  Similarly, when the lid side plate 26 raised on the opposite side presses the protruding portion 21, the protruding portion 21 slides while the R shape 32 is pushed and bent in the state of FIG. After being further raised and the container side plate 27 is no longer in contact, the push-bending state of the protruding portion 21 is released. In this manner, the fitting structure between the protrusion and the notch shown in FIG. 4 is released, and the paper packaging container 1 of FIG. 3 with the lid opened can be obtained, and the lid can be opened. By opening the lid, the consumer can eat the stored confectionery 33.

  Since the paper packaging container 1 of the present embodiment is formed on a side surface different from the main surface of the fitting structure and has a conspicuous structure, the design can be further improved. That is, the main upper surface and the bottom surface do not have a fitting structure, and the side surface portion has a fitting structure that is easily caught by the eyes of consumers at the time of over-the-counter sales. When the fitting structure is provided in this way, for example, the upper surface is the surface, and it is difficult to cause an obstacle such as a printing mode printed on the surface.

  The fitting structure is suitable for the reason that it is inconspicuous if it is in the vicinity of the boundary line (folds m, n) between the upper surface portion and the side surface portion of the paper packaging container 1, but is not limited to this. It can be provided at a position appropriately selected over the entire side surface up to the vicinity of the portion. In addition, the fitting structure is preferably provided on both sides of the upper surface, but is not limited thereto. At least one side direction is sufficient, and even one side may be sufficient as a fitting structure. Contrary to the present embodiment, a fitting structure in which the protruding portion is provided in the lid portion and the notch portion is provided in the container portion may be used.

  In the present embodiment, the protrusion is provided and is easily fitted after being inserted into the notch, but is not limited thereto. It is possible to insert one end of the container upper surface plate 18 without providing the protruding portion, and it is a preferable requirement to provide the protruding portion.

  In the present embodiment, the packaging container has a substantially rectangular parallelepiped shape as a suitable one, but is not limited thereto. A hexahedron is preferable as well as a preferable substantially cubic shape. Furthermore, it can be applied to other three-dimensional solids, for example, a triangular prism shape, an octahedron polyhedron, a bottom plate and a top plate are rectangular, trapezoidal, quadrangular, pentagonal, hexagonal, octagonal, and decagonal paper packaging containers. . In the present embodiment, the side surface has a smaller area than the top surface and the bottom surface, but is not limited thereto, and may have a larger area than the top surface and the bottom surface.

  In the present embodiment, a paper packaging container is illustrated, but is not limited to paper. In the case of using paper, for example, materials used for normal paper processing such as coated cardboard, carton paper, cup base paper, cardboard paper, cardboard (including recycled paper), card paper and the like can be used. The thickness of the paper is not particularly limited, but it is preferable to use high strength paper. In addition, the packaging container may be made from different materials such as plastic material and wood.
