Carton construction

This creation relates to a carton construction, in particular to a carton structure having the effect of displaying the contents of the carton, being easy to stack, and being foldable and assembled by machine.

The traditional carton is closed on six sides in packaging and shipping. After the goods arrive at the destination, they cannot be directly put on shelves and display the contents, and the traditional carton is not used for display on the shelf. However, the use of a displayable package, for example, a package that is divided into a cover and a two-part case, is generally low in height and is not easy to stack on a large number of handling.

In the manufacture of cartons, it is basically necessary to rely on manual assembly, which is inefficient in production and cannot be supplied in large quantities. In general, the carton structure fixed by the glue can be assembled using the machine's production line, but the design of the carton structure itself is fixed by eliminating the glue, and the assembly method is complicated, and it is difficult to assemble the carton by using the machine.

Therefore, in view of the above problems, the present invention provides a carton structure having an effect of displaying contents in a carton, being easy to stack, and being foldable and assembled by a machine.

In order to achieve the above object, the present invention adopts the following technical means:

(1) A carton structure characterized in that it has a quadrangular bottom surface, and the second side wall extending from the bottom surface is provided with two opposite first side walls and two opposite second side walls having an outer portion and an inner surface. The first side wall is provided with a top flap extending into the box body and a side flap for fixing to the second side wall, and each of the side strips and the first side wall are formed by a fold line a protrusion is formed on the top portion, and a notch portion corresponding to the protrusion portion is disposed between the four corners of the bottom surface and the first side wall and the second side wall; the top flap is shorter than one half of the second side wall. Thereby, the box space is displayed.

(2) The carton structure of the above item 1, wherein the top flap is provided with fixing pieces on both sides thereof, and the second side wall is provided with fixing holes corresponding to the fixing pieces; one side of the fixing piece is beyond the fixing hole width One of the oblique sides, and the fixing hole is provided with a cutting opening corresponding to the side of the oblique side beyond the width of the fixing hole, so that the fixing piece is inserted and fixed.

(3) The carton structure according to the above item 1 or 2, wherein the top flap has a curved shape toward one side of the box.

With the creation of the first item, the second side wall of the present carton structure has a double structure to increase the wall thickness to make the carton stronger. In addition, the carton structure is provided with protrusions and notches at four corners, so that the carton can be stably stacked, and the top surface of the carton structure is unclosed, and the contents in the carton can be directly viewed and easily taken. Display function.

By the creation of the second item, the carton structure of the creation is fixed, eliminating the use of adhesive fixing, saving materials and being environmentally friendly. In addition, a cutting opening is provided on one side of the fixing hole, so that one oblique edge beyond the fixed width is inserted into the fixing hole from the cutting hole, which not only assists in the assembly of the carton structure, but also has the effect of fixing. With this fixing method, the carton structure of the present invention can be assembled into a box using a machine.

In addition, as in the creation of item 3, further to the side of the top flap to one side of the box Curved, this technical feature helps to hold the carton better when handling.

Referring to the perspective view of the carton structure of the embodiment shown in Fig. 1, the carton body 1 has a quadrangular bottom surface 10, and the extended bottom surface 10 is provided with two opposite first side walls 11A, 11B and two opposite outer portions 13A, 13B. And a box space surrounded by the second side walls 12A, 12B of the double structure of the inner surface portions 14A, 14B.

The first side wall 11A, 11B is provided with a top flap 22 extending into the box body and The side flaps 16 for fixing to the second side walls 12A, 12B, the fold lines formed by the respective side panels 16 and the first side walls 11A, 11B are extended to the top with protrusions 20, and the four corners of the bottom surface 10 are One side wall 11A, 11B and the second side wall portion 12A, 12B are provided with a notch portion 21 corresponding to the protruding portion 20. As shown in FIG. 3, when a plurality of carton bodies 1 are stacked, the protruding portion 20 is fixed to the notch portion 21 of the other carton body 1, so that the carton bodies 1 are stably stacked.

The top flap 22 is shorter than one half of the length of the second side wall 12A, 12B, so that the box space is displayed.

A fixing piece 23 is disposed on both sides of the top flap 22, and a fixing hole 24 corresponding to the fixing piece 23 is disposed on the second side wall 12A, 12B. Further, in this embodiment, the fixing hole 24 is disposed on the upper surface portion 15A, 15B. One side of the fixing piece 23 is beyond the oblique side of the width of the fixing hole 24, and the fixing hole 24 is provided with a cutting opening 25 corresponding to the side of the oblique side which is beyond the width of the fixing hole 24, so that the fixing piece 23 is inserted and fixed.

Further, the top flap 22 has a curved shape toward one side of the box.

A schematic view of the cardboard structure before assembly of the carton structure of the present embodiment will be described below with reference to Fig. 4 .

As shown in FIG. 4, the first side walls 11A and 11B are extended on the left and right sides of the bottom surface 10, and the second side walls 12A and 12B are extended on the upper and lower sides. The first side walls 11A and 11B are connected to the two ends of the bottom surface 10 and the second side. The side walls 12A, 12B are in contact with the two ends of the bottom surface 10, that is, the four corners of the bottom surface 10 are provided with notches 21.

The side walls 16 are fixed on both sides of the first side wall 11A for fixing to the second side walls 12A, 12B, and the side flaps 16 are inserted in order to leave the fixing pieces 23 inserted. a portion of the first side wall 11A and the bottom side of the first side wall 11A are provided with a protrusion 20; The sheet 22 and the top flap 22 are provided with fixing pieces 23 on both sides thereof. The fixing piece 23 has a beveled edge beyond one of the top flaps 22, and one side of the other side of the top flap 22 is in contact with the first side wall 11A. shape. The first side wall 11B is the same as the above configuration.

The second side wall 12A has a double structure of the outer surface portion 13A and the inner surface portion 14A, and sequentially extends from the bottom surface 10 to the outer surface portion 13A, the upper surface portion 15A, and the inner surface portion 14A. In the present embodiment, the outer surface portion 13A and the upper surface portion 15A A fixing hole 24 corresponding to the fixing piece 23 is disposed, and a cutting hole 25 is disposed on one side of the fixing hole 24 of the upper surface portion 15A, and the cutting hole 25 corresponds to a position of the oblique portion of the fixing piece 23 beyond the top flap 22; Further, side plates 17 are provided on both sides of the inner surface portion 14A, and the side plates 17 have the function of reinforcing the first side walls 11A, 11B.
