The four corners of the corner-wrapped carton are wrapped by the four sharp corners folded from the inside of the box, so that the four corners are fixed and formed. The covered parts overlap each other to make the four sides more straight and neat. The side lengths and heights of the four corners are in the golden ratio, making the box more aesthetically pleasing.

Description

Corner box

technical field

The utility model relates to a daily necessities, in particular to a paper box which is easy to make and can contain small items.

Background technique

There are many kinds of known cartons, some are simple to make, but the thickness of the four sides is uneven; some are complicated to make, but the volume ratio is small.

The invention provides a corner-wrapped paper box, which is characterized by four wrapping corners, has a simple manufacturing method, and has uniform thickness on four sides. It is practical as well as ornamental.

Contents of the invention

In order to overcome the shortcomings of the existing paper box with uneven thickness on the side and low volume ratio due to complex production, the utility model provides a corner-wrapped paper box with a simple and practical manufacturing method.

The technical scheme adopted by the utility model to solve its technical problems is: the upper opening of the carton is opened to be a square; the side of the carton is rectangular, the side length is less than the height, and the side length is 38% of the height; the four corners have four corners; Each wrapping angle is composed of left wrapping angle 1 and right wrapping angle 2, which is the part of an isosceles triangle with an angle of 45 degrees that is higher than the box body at the bottom of the box and folded into the box to wrap the corner of the box; left wrapping angle 1 and The right wrap angle 2 is two isosceles triangles with two bases at 45° angle; the waist connecting the left wrap angle 1 and the right wrap angle 2 is the wrap angle fold 3; the left wrap angle 1 and the right wrap angle 2 are located in the box Two adjacent sides; two wrapping corners on the same side are overlapped; the corner wrapping part is made of four layers of paper; the corner wrapping part is made of seven layers of paper; the bottom of the box is a layer of paper.

The beneficial effect of the utility model is that the four corners of the corner-wrapped carton are wrapped by the four sharp corners folded out of the box, so that the four corners are fixed and shaped. The covered parts overlap each other to make the four sides more straight and neat. The side lengths and heights of the four corners are in the golden ratio, which makes the box more aesthetically pleasing.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Figure 1 is a square paper with folds; the dotted line is the positive fold line, and the circled solid line is the reverse fold line. The four corners are divided into four congruent squares. Squares with four corners are folded in the same way. Take the small square in the upper right corner as an example. Line segment AC is 38% of the side length of the square paper. Line segment AF = line segment DF; line segment BF = line segment EF; line segment BD = line segment ED.

Fig. 2 is a perspective view of a semi-finished product folded according to Fig. 1;

Fig. 3 is a perspective view of the corner-wrapped carton.

In the figure 1, the left wrap angle is composed of two isosceles triangles whose two bases are 45 degree angles; 2, the right wrap angle is composed of two isosceles triangles whose two bases are 45 degree angles; 3, the left wrap angle 1 The crease of the waist connected to the right corner 2.

Detailed ways

The corner-wrapped carton is folded out of a square paper; take the square paper to make a fold, the dotted line is the forward fold line, and the solid line circled is the reverse fold line, as shown in Figure 1.

Fold the square at the four corners according to the creases to form the shape in Figure 2.

Fold the four sharp corners of the upper part according to the crease, and wrap the four corners to form the shape shown in Figure 3, and the corner wrapped carton is completed.

The technical scheme adopted by the utility model to solve its technical problems is: the upper opening of the carton is opened to be a square; the side of the carton is rectangular, the side length is less than the height, and the side length is 38% of the height; the four corners have four corners; Each wrapping angle is composed of left wrapping angle 1 and right wrapping angle 2, which is the part of an isosceles triangle with an angle of 45 degrees that is higher than the box body at the bottom of the box and folded into the box to wrap the corner of the box; left wrapping angle 1 and The right wrap angle 2 is two isosceles triangles with two bases at 45° angle; the waist connecting the left wrap angle 1 and the right wrap angle 2 is the wrap angle fold 3; the left wrap angle 1 and the right wrap angle 2 are located in the box Two adjacent sides; two wrapping corners on the same side are overlapped; the corner wrapping part is made of four layers of paper; the corner wrapping part is made of seven layers of paper; the bottom of the box is a layer of paper.
