[0024] The present invention will be further described below with reference to the specific embodiments of the drawings.

[0025] Embodiment 1:

[0026] like Figures 1 to 5 As shown, a carton is folded using a one-piece piece with an inner corner buffer structure. In this embodiment, the carton is used as a common outer packaging box and is in the shape of a cuboid when in use. The one-piece piece with an inner corner buffer structure includes a main body piece 1 and an inner corner column piece 104 that can constitute the carton. The main body piece 1 is used to form the carton body, and the inner corner column piece 104 is used to form an inner corner column 2 at the intersection of adjacent inner walls of the carton after molding. The main body piece 1 includes four side pieces 101 arranged in a line, and also includes four upper cover pieces 102 and four lower cover pieces 103. The side pieces 101 are used to form the sides of the carton. Figure 1The four side panels 101 are the first side panel, the second side panel, the third side panel and the fourth side panel from left to right. The four side panels 101 are two long and two short. The long and short side panels 101 are arranged at intervals. The longer second side panel and the fourth side panel constitute the longer two side surfaces of the carton, and the shorter first side panel and the third side panel constitute the shorter two end surfaces of the carton. The inner corner column pieces 104 are arranged at intervals and connected in sequence with the side panels 101, that is, the rear end of a side panel 101 is connected to an inner corner column piece 104, and the inner corner column piece 104 is connected to another side panel 101. According to this rule, the inner corner column pieces 104 and the side panels 101 are connected in a string. The upper cover piece 102 and the lower cover piece 103 correspond to each other and are connected to the opposite sides of the side piece 101 respectively. The upper cover piece 102 and the lower cover piece 103 are also different in length. The length of the upper cover piece 102 and the lower cover piece 103 on the longer side piece 101 is also correspondingly longer. The length of the upper cover piece 102 and the lower cover piece 103 is equal to the length of the side piece 101. The side piece 101, the upper cover piece 102, the lower cover piece 103 and the inner corner column piece 104 are integrally formed and are formed by die-cutting and creasing the same two-layer corrugated cardboard. There are folds between the side piece 101 and the inner corner column piece 104, between the side piece 101 and the upper cover piece 102, and between the side piece 101 and the lower cover piece 103, which facilitates the folding parts to be accurately and smoothly folded when the one-piece piece is folded into a carton. The inner corner column piece 104 itself is also provided with two folds, so that when the carton is formed, the inner corner column piece 104 can also be folded along its own folds into a straight triangular prism-shaped inner corner column 2, and the two side surfaces of the inner corner column 2 are respectively correspondingly fitted with two adjacent side pieces 101. In this embodiment, the cross section of the inner corner column 2 is an isosceles triangle.

[0027] The process of folding the one-piece cut piece with the inner corner buffer structure into a direction is as follows: first, the third side piece and the fourth side piece are folded close together to form an angle of approximately 90°, and the inner corner column cut piece 104 between the third side piece and the fourth side piece is also folded within the angle between the third side piece and the fourth side piece. The inner corner column cut piece 104 is folded along its two folds to form a straight triangular prism-shaped inner corner column 2. At the same time, the inner corner column cut piece 104 is folded along the fold between the third side piece and the fold between the fourth side piece, so that the two sides of the inner corner column 2 are respectively attached to the third side piece and the fourth side piece. When the third side piece and the fourth side piece intersect and contact to form a ridgeline of the carton, the third side piece and the fourth side piece are adhered and fixed on the outside of the side piece 101 with adhesive tape. According to the above method, the second side piece and the third side piece are adhered and fixed, and the first side piece and the second side piece are adhered and fixed to form a corresponding inner corner column 2. Finally, the first side piece is brought close to the fourth side piece and fixed with adhesive tape, so that the four side pieces 101 are connected end to end to form a closed side surface of the carton, and the side surface of the inner corner column 2 between the first side piece and the fourth side piece needs to be separately attached to the first side piece with adhesive tape for reinforcement. Then, each lower cover piece 103 is folded into place and glued with adhesive tape to form the bottom of the carton, and the carton is basically formed and ready for use.

[0028] Embodiment 2:

[0029] A carton is formed by folding a one-piece cut piece with an inner corner buffer structure. In this embodiment, the carton is used as a common outer packaging box and is in the shape of a cuboid when in use. The one-piece cut piece with an inner corner buffer structure includes a main cut piece 1 and an inner corner column cut piece 104 that can constitute the carton. The main cut piece 1 is used to form the main body of the carton, and the inner corner column cut piece 104 is used to form an inner corner column 2 at the intersection of adjacent inner walls of the carton after molding. The main cut piece 1 includes four side pieces 101 arranged in a line, and also includes four upper cover pieces 102 and four lower cover pieces 103. The side pieces 101 are used to form the sides of the carton. Figure 1 The four side panels 101 are the first side panel, the second side panel, the third side panel and the fourth side panel from left to right. The four side panels 101 are two long and two short. The long and short side panels 101 are arranged at intervals. The longer second side panel and the fourth side panel constitute the longer two side surfaces of the carton, and the shorter first side panel and the third side panel constitute the shorter two end surfaces of the carton. The inner corner column pieces 104 are arranged at intervals and connected in sequence with the side panels 101, that is, the rear end of a side panel 101 is connected to an inner corner column piece 104, and the inner corner column piece 104 is connected to another side panel 101. According to this rule, the inner corner column pieces 104 and the side panels 101 are connected in a string. The upper cover piece 102 and the lower cover piece 103 correspond to each other and are connected to the opposite sides of the side piece 101 respectively. The upper cover piece 102 and the lower cover piece 103 are also different in length. The length of the upper cover piece 102 and the lower cover piece 103 on the longer side piece 101 is also correspondingly longer. The length of the upper cover piece 102 and the lower cover piece 103 is equal to the length of the side piece 101. The side piece 101, the upper cover piece 102, the lower cover piece 103 and the inner corner column piece 104 are integrally formed and are formed by die-cutting and creasing the same two-layer corrugated cardboard. There are folds between the side piece 101 and the inner corner column piece 104, between the side piece 101 and the upper cover piece 102, and between the side piece 101 and the lower cover piece 103, which facilitates the folding parts to be accurately and smoothly folded when the one-piece piece is folded into a carton. The inner corner column cut piece 104 itself is also provided with two folds, so that when the carton is formed, the inner corner column cut piece 104 can also be folded along its own folds into a straight triangular prism-shaped inner corner column 2, and the two side surfaces of the inner corner column 2 are respectively correspondingly fitted with two adjacent side panels 101. Different from the embodiment 1, the cross section of the inner corner column 2 in this embodiment is not an isosceles triangle. When the carton is in use, the three angles of the cross section triangle of the inner corner column 2 are approximately 40°, 50°, and 90°, respectively.

[0030] The process of folding the one-piece cut piece with the inner corner buffer structure into a direction is as follows: first, the third side piece and the fourth side piece are folded close together to form an angle of approximately 90°, and the inner corner column cut piece 104 between the third side piece and the fourth side piece is also folded within the angle between the third side piece and the fourth side piece. The inner corner column cut piece 104 is folded along its two folds to form a straight triangular prism-shaped inner corner column 2. At the same time, the inner corner column cut piece 104 is folded along the fold between the third side piece and the fold between the fourth side piece, so that the two sides of the inner corner column 2 are respectively attached to the third side piece and the fourth side piece. When the third side piece and the fourth side piece intersect and contact to form a ridgeline of the carton, the third side piece and the fourth side piece are adhered and fixed on the outside of the side piece 101 with adhesive tape. According to the above method, the second side piece and the third side piece are adhered and fixed, and the first side piece and the second side piece are adhered and fixed to form a corresponding inner corner column 2. Finally, the first side piece is brought close to the fourth side piece and fixed with adhesive tape, so that the four side pieces 101 are connected end to end to form a closed side surface of the carton, and the side surface of the inner corner column 2 between the first side piece and the fourth side piece needs to be separately attached to the first side piece with adhesive tape for reinforcement. Then, each lower cover piece 103 is folded into place and glued with adhesive tape to form the bottom of the carton, and the carton is basically formed and ready for use.

The side piece 101 is used to form the side of the carton. Figure 6The four side panels 101 in the middle are the first side panel, the second side panel, the third side panel and the fourth side panel from left to right. The four side panels 101 are two long and two short. The long and short side panels 101 are arranged at intervals. The longer second side panel and the fourth side panel constitute the longer two side surfaces of the carton, and the shorter first side panel and the third side panel constitute the shorter two end surfaces of the carton. The inner corner column pieces 104 are arranged at intervals and connected in sequence with the side panels 101, that is, the rear end of a side panel 101 is connected to an inner corner column piece 104, and the inner corner column piece 104 is connected to another side panel 101. According to this rule, the inner corner column piece 104 and the side panel 101 are connected in series. The lower cover panel 103 also has different lengths. The length of the lower cover panel 103 on the longer side panel 101 is also correspondingly longer, and the length of the lower cover panel 103 is equal to the length of the side panel 101. The side piece 101, the lower cover piece 103 and the inner corner column piece 104 are integrally formed. Different from the first embodiment, the side piece 101, the lower cover piece 103 and the inner corner column piece 104 are formed by die-cutting and creasing the same three-layer corrugated paperboard. There are folds between the side piece 101 and the inner corner column piece 104, and between the side piece 101 and the lower cover piece 103, which facilitates the folding part to be accurately and smoothly folded when the one-piece piece is folded into a carton. The inner corner column piece 104 itself is also provided with two folds, so that when the carton is formed, the inner corner column piece 104 can also be folded into a straight triangular prism-shaped inner corner column 2 along its own folds, and the two side surfaces of the inner corner column 2 are respectively correspondingly fitted with two adjacent side pieces 101. In this embodiment, the cross section of the inner corner column 2 is an isosceles triangle.

[0033] The process of folding the one-piece cut piece with the inner corner buffer structure into a direction is as follows: first, the third side piece and the fourth side piece are folded close together to form an angle of approximately 90°, and the inner corner column cut piece 104 between the third side piece and the fourth side piece is also folded within the angle between the third side piece and the fourth side piece. The inner corner column cut piece 104 is folded along its two folds to form a straight triangular prism-shaped inner corner column 2. At the same time, the inner corner column cut piece 104 is folded along the fold between the third side piece and the fold between the fourth side piece, so that the two sides of the inner corner column 2 are respectively attached to the third side piece and the fourth side piece. When the third side piece and the fourth side piece intersect and contact to form a ridgeline of the carton, the third side piece and the fourth side piece are adhered and fixed on the outside of the side piece 101 with adhesive tape. According to the above method, the second side piece and the third side piece are adhered and fixed, and the first side piece and the second side piece are adhered and fixed to form a corresponding inner corner column 2. Finally, the first side piece is brought close to the fourth side piece and fixed with adhesive tape, so that the four side pieces 101 are connected end to end to form a closed side surface of the carton, and the side surface of the inner corner column 2 between the first side piece and the fourth side piece needs to be separately attached to the first side piece with adhesive tape for reinforcement. Then, each lower cover piece 103 is folded into place and glued with adhesive tape to form the bottom of the carton, and the carton is basically formed and ready for use.

[0034] Embodiment 4:

[0035] A carton is formed by folding a one-piece cut piece with an inner corner buffer structure. Different from Example 1, the carton in this embodiment is used as a gift packaging box and is in the shape of a regular hexagonal prism when in use. The one-piece cut piece with an inner corner buffer structure includes a main cut piece 1 and an inner corner column cut piece 104 that can constitute the carton. The main cut piece 1 is used to form the main body of the carton, and the inner corner column cut piece 104 is used to form an inner corner column 2 at the intersection of adjacent inner walls of the carton after forming. The main cut piece 1 includes six side pieces 101 arranged in a line, and also includes six upper cover pieces 102 and six lower cover pieces 103. The side pieces 101 are used to form the sides of the carton. The six side pieces 101 are sequentially the first side piece, the second side piece, the third side piece, the fourth side piece, the fifth side piece and the sixth side piece from one end to the other end, and the six side pieces 101 are equal in length. The inner corner column pieces 104 and the side pieces 101 are arranged at intervals and connected in sequence, that is, the rear end of a side piece 101 is connected to an inner corner column piece 104, and the inner corner column piece 104 is connected to another side piece 101. According to this rule, the inner corner column pieces 104 and the side pieces 101 are connected in a series. The upper cover piece 102 and the lower cover piece 103 correspond to each other and are respectively connected to the opposite sides of the side piece 101. The upper cover piece 102 and the lower cover piece 103 are both equilateral triangles, and a connecting tongue is integrally provided on one side of each upper cover piece 102, which is used to bond and close the adjacent upper cover pieces 102 when the carton is used. The lower cover piece 103 is also provided with a connecting tongue with the same function as above. The side lengths of the upper cover piece 102 and the lower cover piece 103 are equal to the length of the side piece 101. The side piece 101, the upper cover piece 102, the lower cover piece 103 and the inner corner column piece 104 are integrally formed, and are formed by die-cutting and creasing the same two-layer corrugated paperboard. There are folds between the side piece 101 and the inner corner column piece 104, between the side piece 101 and the upper cover piece 102, and between the side piece 101 and the lower cover piece 103, which facilitate the folding part to be accurately and smoothly folded when the one-piece piece is folded into a carton.

The inner corner column cut piece 104 is folded along its two folds to form a straight triangular prism-shaped inner corner column 2. At the same time, the inner corner column cut piece 104 is folded along the fold between the fifth side piece and the fold between the sixth side piece, so that the two side surfaces of the inner corner column 2 are respectively attached to the fifth side piece and the sixth side piece. Different from Example 1, when the fifth side piece and the sixth side piece intersect and contact to form an edge line of the carton, the fifth side piece and the sixth side piece are bonded and fixed at the joint part with quick-drying glue. According to the above method, the fourth side piece, the fifth side piece, the third side piece, the fourth side piece, the second side piece, the third side piece, the first side piece, the second side piece are all bonded and fixed to form corresponding inner corner columns 2. Finally, the first side piece is brought close to the sixth side piece and bonded and fixed with quick-drying glue, so that the four side pieces 101 are connected end to end to form the closed side surface of the carton. The side surface of the inner corner column 2 between the first side piece and the sixth side piece needs to be bonded and reinforced with the first side piece separately with glue. Then, each lower cover piece 103 is folded into place and bonded with glue to form the bottom of the carton. The carton is basically formed and ready for use.
