Description

  The present invention relates to a packaging box, and more particularly to a packaging box in which a sheet-like material is folded into a rectangular parallelepiped.

  As another example of a conventional packaging box, a rear panel, a side panel, a front panel, a side panel, and a sticking piece are connected via a folding line, and a ceiling panel is connected to the top of the rear panel via a folding line. An open / close panel is connected to the top panel via a folding line, a top panel and an insertion piece are sequentially connected to the top of the front panel via a folding line, and the surface of the sticking piece and the back surface of the rear panel A carton that forms a cylindrical body by providing an opening region surrounded by a break line and a part of an edge of the front panel on the front panel, and the opening / closing panel on the upper surface of the front panel A thin easy-open carton has been proposed in which the opening region and the back surface of the open / close panel are bonded to each other (for example, see Patent Document 1).

  In the thin easy-open carton proposed by Patent Document 1, a certain area on the upper surface is doubled, and it is possible to obtain a three-dimensional effect, beauty of overlay, alertness, fun, etc., rather than simple flat printing. . In addition, the edge part that is recognized only after opening is formed in the lower sheet material of the double part in a desired shape, and the range of use of the packaging box after opening is expanded, or the strength as a packaging box due to the upper surface remaining part It is also possible to secure this. However, when a large number, for example, 12 of the thin easy-open cartons proposed by Patent Document 2 are stacked, the height of the vertical direction, that is, the thickness of the thin easy-open cartons is the sheet material in the single part and double part of the upper surface. There is a problem that the thin easy-open carton gradually tilts as it goes upwards, and it becomes difficult to integrally wrap the entire stack.

  As still another example of a conventional packaging box, a rectangular tube body formed by connecting a back plate, a lower plate, an upper plate, and a front plate, and the back plate, the lower plate, the upper plate, and the front plate, respectively. A side portion for sealing the rectangular tube-shaped body portion formed by side flaps continuously provided on the side of the upper plate, and an upper portion of the front plate that is continuous with the upper plate and overlapped with the front plate 4 surface. Formed by a top cover plate attached to the surface of the opening pattern region 6 formed by a cut-off portion, and the side flap of the front plate is formed from the side flap surface of the back plate and the notch formed in the flap. There has been proposed a carton that is laminated and adhered to the exposed side flap surface (see, for example, Patent Document 2).

  In the carton proposed by Patent Document 2, a certain area on the upper surface is doubled, and a three-dimensional effect, a superb overlay beauty, alertness, interestingness, and the like can be obtained rather than simple planar printing. In addition, the opening pattern region is cut in half in the lower sheet material of the double part, the edge that is recognized only after opening is made into a desired shape, and the use range of the packaging box after opening is expanded, It is also possible to ensure the strength as a packaging box by the upper surface remaining portion. However, when a large number, for example, 10 or more of the cartons proposed by Patent Document 3 are stacked, the vertical height, that is, the thickness of the carton differs by the thickness of the sheet material between the single portion and the double portion of the upper surface. However, there is a problem that the thin easy-open carton gradually tilts as it goes upward, and it becomes difficult to integrally wrap the entire stack.

  In another embodiment of the present invention, the width of the upper surface outer panel flap in the direction of the one row is less than the width of the upper surface outer panel in the direction of the row when the thickness of the sheet-like material is t. It is characterized by being 5t to 1.5t smaller.

  According to this embodiment, the same packaging box manufacturing apparatus as the conventional one is used, and no special work is required, and the effects of the present invention can be obtained.

It is a top view of the sheet-like material which creates the packaging box of this invention. It is a perspective view of the packaging box of this invention. It is a perspective view of the opened state of the packaging box of this invention. It is a perspective view of the resealed state of the packaging box of this invention.

  Embodiments of the packaging box of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the sheet-like material 10 forming the packaging box 1 includes an upper surface inner panel 12, an upper surface inner panel 14, a bottom panel 16, an upper surface outer panel 18, and an upper surface outer panel 20 via a folding line b. It is provided in a row. The folding line b can be easily bent as desired by lowering the rigidity of the desired cutting line position by providing a partially connected lead ruled line, perforation line, ruled line, half cut line, etc. To. Let the thickness of the sheet-like material 10 be t.

  The sheet-like material 10 is further provided with an upper surface side panel 30 at both ends in a direction perpendicular to the direction of the one row of the upper inner panel 12 (hereinafter referred to as a single line direction), and upper surfaces at both ends of the upper inner panel 14. The bottom panel 34 is provided at both ends of the inner panel flap 32 and the bottom panel 16, and the top outer panel flap 36 is provided at both ends of the top outer panel 18.

  The top inner panel 12 has substantially the same shape and dimensions as the bottom panel 16, but is provided with an open half-cut line 52 that forms an opening 50 when the packaging box 1 is opened. The opening half-cut line 52 is provided with cuts and connecting portions alternately along the cut line. The upper inner panel 12 is also provided with a temporary sealing cut 54 for inserting a temporary sealing protrusion 72 described later.

  The upper surface inner panel 14 and the upper surface outer panel 18 have substantially the same shape and dimensions, but the upper surface outer panel 18 is configured to increase the rigidity of the packaging box being opened. That is, after opening, the region near the folding line b on the upper surface outer panel flap 36 side in the upper surface outer panel 18 is made substantially integral with the upper surface side panel 30, the bottom surface side panel 34, and the upper surface outer panel flap 36. Therefore, the upper outer panel 18 has two half-cut curves 19 from the folding line b between the upper outer panel 18 and the upper outer panel 20 to the folding line b between the bottom panel 16 and the upper outer panel 18.
