Description

A non-cutting and non-pasting clamshell carton and its folding method

technical field

The invention relates to a flip-top carton without cutting and pasting and a folding method thereof.

Background technique

There are two main types of existing non-cutting and non-sticking clamshell cartons:

The first is to set creases, fold the cardboard along the creases to form a general box shape, and then use a bonding process to bond the parts that are abutting together to maintain the box shape. It has the following disadvantages: the processing technology is complicated, the environmental protection performance is poor, and it can only be destructively removed after bonding.

The second is to set creases, set specific structures on the edge of the cardboard, fold the cardboard along the creases to form a general box shape, and then insert the corresponding specific structures to maintain the box shape. It has the following disadvantages: a cutting process is required, the processing process is complicated, and the cost is high.

The four horizontal creases 11, 12, 13, 14 are respectively the first horizontal crease 11, the second horizontal crease 12, the third horizontal crease 13, and the fourth horizontal crease 14 arranged in sequence. The longitudinal creases 15 and 16 are divided into a first longitudinal crease 15 and a second longitudinal crease 16 arranged in sequence from left to right. The spacing between the first transverse crease 11 and the front edge of the cardboard, the spacing between the second transverse crease 12 and the third transverse crease 13, the spacing between the fourth transverse crease 14 and the rear edge of the cardboard are equal; the first transverse crease 11 and the The spacing of the second transverse crease 12, the spacing of the third transverse crease 13 and the fourth transverse crease 14 are equal; The spacing is equal; the spacing between the first longitudinal crease 15 and the left edge of the cardboard, and the spacing between the first transverse crease 11 and the front edge of the cardboard are equal. Both the transverse and longitudinal creases run through the paperboard.

The part between the two transverse creases 12 and 13 in the middle constitutes a rear wall 24 between the two longitudinal creases 15 and 16 and two square parts 31 respectively located on the left and right sides of the rear wall 24. The diagonal lines are all set as the first oblique creases 32 .

A lower front wall 25 between the two longitudinal folds 15, 16 and two lower folded parts 33 respectively located on the left and right sides of the lower front wall 25 are formed between the frontmost horizontal fold 11 and the front side of the cardboard 10. The folding part 33 is provided with at least one second oblique crease 34 along at least one diagonal line; as required, two second oblique creases 34 can be provided along the two diagonal lines. A second oblique crease 34. At this time, the starting point of the diagonal line is the junction of the frontmost transverse crease and the two longitudinal creases. Between the transverse crease 14 on the rearmost side and the rear side of the cardboard 10, an upper front wall 23 between the two longitudinal creases 15, 16 and two upper folded parts 35 respectively located on the left and right sides of the upper front wall 23 are formed. The folded portion 35 is provided with two third oblique creases 36 along the two diagonals. The upper folded portion 35 and the lower folded portion 33 have the same structure and form a square structure.

Fold the cardboard 10 along the transverse creases 11, 12, 13, 14, longitudinal creases 15, 16, first oblique crease 32, second oblique crease 34, third oblique crease 36 to form the lower front wall of the carton 25. One upper front wall 23, one rear wall 24, one box cover 21 between the third horizontal crease 13 and the fourth horizontal crease 14 and two vertical creases 15, 16, one between the first horizontal crease 11 and the second horizontal crease 12 and the bottom box 22 between the two vertical creases 15 and 16, two upper side walls 26 and 28 that are respectively located on the left and right sides of the box cover 21, and two upper side walls that are respectively located on the left and right sides of the bottom box 22. Lower side walls 27,29.

The upper front wall 23 is located in front of the lower front wall 25 , and the isosceles triangular upper folded portion 35 formed by folding along the third oblique crease 36 is pressed against the lower front wall 25 and the upper front wall 23 .

For example, to facilitate folding, it is better to reduce the height of the lower side wall. Then, the connection points of the frontmost transverse crease 11 and the two vertical creases 15, 16 are respectively located at a point on the side edge of the lower side wall 27, 29. A fourth oblique crease 37 is extended. Preferably, the length of the fourth oblique crease 37 is consistent with the length of the second oblique crease. When in use, the lower side wall can be bent along the fourth oblique crease 37 to reduce the height of the front upper end of the lower side wall, so that the lower side wall The distance from the rear lower point to the front upper point of the lower side wall is roughly equal to the length of the upper side wall, which is convenient for flip-top cartons without cutting and pasting, and it is convenient to open or close the cartons smoothly.
