Description

Carton with cutting function

Technical Field

The utility model relates to the technical field of cartons, in particular to a carton with a cutting function.

Background

Packing carton all kinds on the market, the variety is various, and people also more and more attach importance to the quality and the practical function of packing carton itself when putting attention to packing carton structure, style pleasing to the eye, and good packing carton not only will play protection product, be convenient for circulate, deposit, pleasing to the eye basic function such as clean and tidy, should realize more abundant functions still. For example, a paper box for storing long roll paper and a paper box for storing preservative films not only need to protect the roll paper or the preservative films cleanly and neatly, but also can further provide the cutting function of the roll paper or the preservative films, and provide convenience for users to use. The existing paper box with the cutting function is often provided with a cutting device at a proper position of the paper box or the paper box, the cutting device is used for cutting the roll paper or the preservative film, but the adopted cutting device is often a cutting edge made of other materials, such as metal, so that when the paper box is manufactured, the processing step of fixing the cutting edge is needed, the material cost is increased, and the labor cost is also increased. In addition, when the paper box is recycled, the paper box body and the knife edge are different materials, so that sorting is also needed for separate recycling, which increases the cost of resource recycling.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art and provide a paper box with a cutting function, which is made of paper materials, is safe and environment-friendly and has low production cost.

The technical scheme of the utility model is as follows: a paper box with cutting function comprises a blank plate which can form a box body after being folded and pasted, wherein the blank plate is integrally cut from a hard paper material and comprises a panel and end plates, the end plates are positioned at two sides of the panel, one edge of the panel is a sawtooth edge, a sawtooth structure is arranged on the sawtooth edge, a tearing part is arranged on the panel, and the tearing part is pre-cut to reduce the connectivity of the tearing part and the panel and is easy to tear off the blank plate; after the blank forms the box body, the sawtooth edge on the panel is positioned outside the box body and corresponds to the tearing part. And after the tearing part is torn, the roll-shaped object in the box body can penetrate out of the opening structure left at the position, and is contacted with the sawtooth edge and cut.

Further, the panel is processed by an indenter to form a plurality of indentations which are convenient to fold. Preferably, the indentations are 4 and the panel is divided into 5 parallel small areas.

Furthermore, the tearing part is arranged on a small area farthest from the sawtooth edge, and after the tearing part is torn down, the roll-shaped object in the box body can penetrate out from the left opening.

Further, the tearing part is in an elongated shape, and preferably, the length of the tearing part is adapted to the length of the sawtooth structure on the sawtooth edge.

Further, the width of the tearing part is 5-10 mm.

Furthermore, the tearing part is parallel to the sawtooth edge, so that the shape of the cut roll-shaped object can be ensured to be more regular. Certainly, the tearing part and the serrated edge can be not parallel, so that the roll can be in contact with the serrated edge sequentially, and the roll is more labor-saving, for example, in some embodiments, the serrated edge on the panel can be in an inverted V shape, only the middle serrated edge is in contact with the roll at first, so that the contact area between the serrated edge and the roll is smaller, and according to a system of the stress area and the pressure, when the contact area is smaller, the same force is used, and larger pressure intensity can be generated. In other embodiments, the overall shape of the serrated edge 3 may be wavy, with a viewing port in the panel to facilitate viewing of the remainder of the roll inside the carton.

Compared with the prior art, the utility model has the beneficial effects that: the paper box provided by the utility model can be made of paper materials, so that the manufacturing process is effectively reduced, the manufacturing cost is greatly reduced, and the convenience in environmental protection and recovery is realized.

Detailed Description

The present invention will be described in further detail below with reference to specific examples, wherein methods or features not specifically described are known in the art.

Example 1

As shown in fig. 1, the paper box with cutting function includes a blank 1 which can be folded and pasted to form a box body, the whole blank 1 is made by cutting a hard paper material, the blank 1 includes a panel 11 and an end plate 12, the end plate 12 is located at two sides of the panel 11, one side of the panel 11 is a sawtooth edge 3 on which a sawtooth structure is arranged, a tearing part 2 is arranged on the panel 11, the tearing part 2 is pre-cut to reduce the connectivity with the panel 11, and is easy to tear off from the blank 1; when the blank 1 is formed into a box, the serrated edge 3 on the panel 11 is located outside the box and corresponds to the position of the tearing part 2. And after the tearing part 2 is torn off, the roll-shaped object in the box body can penetrate out from the opening structure left at the position, and is contacted with the sawtooth edge 3 and cut.

The panel 11 in this embodiment is processed by an indenter to form 5 indentations for easy folding, the indentations divide the panel 11 into 5 parallel small areas, and the tear portion 2 is disposed on the small area farthest from the serrated edge 3. Tearing portion 2 is rectangular form, and the length of tearing portion 2 suits with the length of sawtooth structure on the sawtooth limit 3, and the width of tearing portion 2 is 10 mm.

The tearing part 2 in the embodiment is parallel to the sawtooth edge 3, so that the shape of the cut roll-shaped object can be ensured to be more regular.

Example 2

As shown in fig. 2, the present embodiment 2 is different from embodiment 1 only in that: in the embodiment, the sawtooth edge 3 is arranged in an inverted V shape, so that the tearing part 2 is not parallel to the sawtooth edge 3, when the cutting device is used, the middle of the sawtooth edge 3 is firstly contacted with the roll, the contact area between the sawtooth edge 3 and the roll is small, and the roll (such as a preservative film) is subjected to larger pressure, so that the roll is cut more easily.

In other embodiments, in order to ensure the strength of the serrated edge 3, a layer of colloid can be coated on the serrated edge 3, and the colloid has waterproof performance and prevents the paper from softening by absorbing water.

In other embodiments, the whole shape of the serrated edge 3 may also be wavy, a viewing port is provided on the panel to facilitate viewing of the remaining state of the roll inside the carton, and the viewing port may also be provided on the end plates, that is, corresponding notches may be provided on some end plates on the same side of the blank 1, so that after the carton is formed, a viewing port penetrating through the carton body is formed on the end surface of the carton body.

The present invention is not limited to the above embodiments, and various combinations and modifications of the above technical features may be provided for those skilled in the art, and modifications, variations, equivalents, or uses of the structure or method of the present invention in other fields without departing from the spirit and scope of the present invention are included in the protection scope of the present invention.
