In order to make the technical solution of the present invention better understood, the technical solution of the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

The embodiment of the utility model discloses carton, as shown in fig. 1, fig. 2, it forms to link to each other in proper order by a plurality of cardboard, the cardboard includes curb plate 21, page or leaf board 22, link to each other through curb plate 21 between the cardboard, be equipped with kink 23, at least one between curb plate 21, the page or leaf board 22 be equipped with tangent line 3 on the kink 23 of cardboard, tangent line 3 comprises one or a plurality of incision 31, incision 31 sets up in the cardboard inboard.

As shown in fig. 1 and 2, the top and bottom edges of the side plate 21 are provided with leaf plates 22. The bending part 23 is a crease structure formed by pressing the paperboard in the production process. The tangent lines 3 are arranged in sequence along the extension direction of the bending portion 23.

The embodiment of the utility model provides a through set up tangent line 3 on the kink 23 of cardboard, carry out small destruction to the cardboard structure to reduce the anti-power of dialling that produces when buckling between curb plate 21 and the page or leaf board 22, avoid the carton to open because of anti-power of dialling when cohering the closure, improve the carton seal.

Optionally, as shown in fig. 3, the paperboard is corrugated paperboard, and the cut 31 is a half-through knife cut 31.

The paperboard is a corrugated paperboard and is composed of an inner layer 231, a support layer 232 and an outer layer 233, the cut 31 is arranged on the inner layer 231, and the bottom of the cut 31 is located on the support layer 232.

The embodiment of the utility model provides a through adopting half wearing sword incision 31, make the outer 233 surface of cardboard complete, and inside supporting layer 232 forms small destruction, has effectively reduced the anti-power of dialling of cardboard when buckling, makes the carton surface level and smooth no incision 31 simultaneously, when playing pleasing to the eye, ensures that carton structure itself still can be equipped with good stability.

Alternatively, the tangent 3 is composed of several slits 31 arranged in a straight line.

The embodiment of the utility model provides an in order to equidistant linear arrangement along between each incision 31.

Optionally, as shown in fig. 1, the number of the paper boards is four, and the paper boards are respectively a first main paper board 11, a first side paper board 12, a second main paper board 13, and a second side paper board 14, the first main paper board 11, the first side paper board 12, the second main paper board 13, and the second side paper board 14 are sequentially connected, the flap 22 of the first main paper board 11 is a carton cover plate structure, and the bending portion 23 of the second main paper board 13 is provided with a tangent line 3.

Wherein, the tangent line 3 is only arranged on the bending part 23 of the second main paper board 13, and in actual use, the tangent line 3 can be also arranged on the first main paper board 11, the first side paper board 12, the second main paper board 13 and the second side paper board 14.

In particular, as shown in fig. 1 and 6, the width of at least one of the flaps 22 of the second main blank 13 is no greater than three-quarters of the width of the carton in the closed position.

Wherein, the width is the length of the short side of the page plate and the carton on the horizontal plane in a closed state; if the projection of the page or the carton on the horizontal plane is a trapezoid structure, the width refers to the shortest distance between two long sides of the page.

The width of the page plates 22 of the traditional carton is similar to or the same as that of the carton in a closed state, so that the page plates 22 can completely cover the opening of the carton, and sealing can be realized by matching with the pressing of a cover plate structure of the carton; with the increase of environmental awareness, in order to achieve a paper saving effect, the width of the sheet 22 is reduced in some types of cartons, and the amount of paper used is ensured to be reduced on the premise that sealing is not affected. However, this structure makes the leaf 22 only cover the opening of the carton, and at this time, due to the reduction of the width of the leaf 22, as shown in fig. 11, the contact position of one end of the leaf 22 and the carton cover structure is moved, and the end of the leaf 22 is shortened due to the moment, so that the anti-poking force is increased, which affects the normal closing of the carton.
