Description

Manual eight-square box cutting piece

Technical Field

The utility model belongs to the technical field of folding carton technique and specifically relates to a manual eight corner box cut-parts.

Background

Cartons are common packages, with rectangular corner cartons being the most common. Taking the common four-corner carton as an example, from the analysis of mechanical angle, on the premise of equal circumference and consistent thickness, the more the number of the edges of the enclosing shape of the side wall in the stress direction is, the more the side wall tends to be circular, and the better the stress strength is. Due to the limitation of packaging, storage and transportation, if the side wall of the carton in the stress direction is made into a cylindrical shape, the cost, the bearing effect and the space occupation are not ideal. If can improve on the basis of current four corners carton, form more continuous vertical lateral wall, just can improve the vertical atress effect of carton by a wide margin after enclosing. Octagonal box is the improvement of going on this basis, and octagonal box has the inconvenient problem of production folding among the prior art.

For example, chinese patent document CN 210708351U discloses an octagonal carton, comprising: the left side of the front plate is connected with the first left plate in a bendable manner, the right side of the front plate is connected with the first right plate in a bendable manner, the left side of the rear plate is connected with the third left plate in a bendable manner, the right side of the rear plate is connected with the third right plate in a bendable manner, the parallel two sides of the second left plate are respectively connected with the first left plate and the third left plate in a bendable manner, and the parallel two sides of the second right plate are respectively connected with the first right plate and the third right plate in a bendable manner; and the tearing guide sheet is formed by encircling broken lines arranged at intervals and is arranged on the top sealing cover plate and the front plate. The disadvantages are that: the butt-positive performance is poor, the top sealing cover plate and the bottom sealing cover plate are both of special-shaped structures, and the box opening device or the top sealing cover plate and the bottom sealing cover plate must be matched during folding forming, so that the box opening device cannot be formed or is not formed properly, and the production efficiency is low.

Disclosure of Invention

Based on prior art's the aforesaid is not enough, the utility model provides a manual eight angle case cut-parts can be folding by pure hand, need not with the help of the instrument, and the practicality is good.

In order to achieve the above purpose, the present invention adopts the following technical solution.

A manual octagonal box cut-parts is characterized by comprising four coaxially arranged side plates, wherein the four side plates are alternately arranged in a congruent manner, transition angle plates are respectively arranged on the same sides of the four side plates on an axis, the adjacent side plates are connected through the transition angle plates, cover plates and bottom plates are respectively arranged at two ends of each side plate, and sealing edges corresponding to the transition angle plates are arranged on the bottom plates and the cover plates on at least two congruent side plates; the cover plates and the bottom plates at the two ends of the side plate are symmetrically arranged around the axis of the side plate.

Compared with the special-shaped structure in the prior art, the cut pieces are of the axisymmetric structure, so that the alignment is good, the carton can be manually formed without tools, and the squareness and regularity of the carton are ensured; has higher application prospect and commercial value; the reliable cooperation that the bottom plate curb plate can be accomplished to being equipped with the edge of sealing on bottom plate and the apron on having two congruent curb plates, also can increase the edge of sealing structure on bottom plate and the apron that correspond to other curb plate on the basis of two congruent curb plates certainly, can improve structural strength.

Preferably, the length of the edge of the seal is equal to the length of the corresponding transition gusset. The reliability of the sealing edge and the sealing edge of the transition angle plate is ensured.

Preferably, the sealing edge is located at one end of the cover plate and the bottom plate which are attached to the side plates, and the sealing edge is obliquely arranged from the long side plate. Simple structure and convenient cutting and forming.

Preferably, the cover plate and the bottom plate corresponding to the two ends of the short side plate are both rectangular in shape. The shaping is made conveniently, and the apron and the bottom plate at short curb plate both ends can play the effect of inside lining as apron and bottom plate on the long curb plate, strengthen the intensity of eight angle boxes.

Preferably, the outermost transition corner plate is provided with a connecting edge or the outermost side plate is provided with a connecting edge. Make things convenient for four blocks of curb plates and four pieces of transition scutches to connect through the flange and circularize, can adopt modes such as sticky or nail admittedly, cut-parts folding forming is convenient.

Preferably, the connecting edge is shaped like an isosceles trapezoid, and an included angle formed by the waist of the connecting edge is arranged outwards. The both ends of connecting plate form chamfer structure, simple to operate.

Preferably, the manual octagonal box cutting piece is made of corrugated paper. The cut pieces need to be of sufficient strength and thickness so that a suitable corrugated paper is selected and the length direction of the corrugations is recommended to be arranged along the height direction of the side panels.

The utility model discloses following beneficial effect has: the symmetry is good, the cutting and forming of cut pieces are convenient, and the arrangement of a cutting die is simple; the folding device is convenient to fold, can be folded by hands without tools, and has high folding efficiency, good practicability and high commercial value.
