Description

Carton capable of being folded and recycled quickly

Technical Field

The utility model relates to the field of packaging, in particular to a carton capable of being folded and recycled quickly.

Background

The folding carton is a packaging container with the widest application range and the most changed structure and shape. It is made of a folding-resistant paperboard with the thickness of 0.3-1.1mm, and can be unfolded and stacked in a flat mode for transportation and storage before being filled with contents, the length of the sheet material is the perimeter of the carton plus the width of a side sealing edge 4, two sides of the sheet material in the length direction of the carton are inwards opened, and a middle box body 3, a lower sealing bottom 2 and an upper side tongue 1 of the carton are separated. Conventional rectangular cartons suffer from the following disadvantages: the upper cover plate is often closed by bending the first pair of upper tongues (usually the short upper tongues) of the opposite sides inwards, and then bending the second pair of upper tongues (the long upper tongues) inwards to press the short upper tongues, so that the upper tongues cannot close the upper ends snugly without being fixed by adhesive tape. When the carton will recycle, if carry out the pile when using as the turnover case and deposit, need joint sealing, unpacking convenience, still need recycle, use the sticky tape joint sealing not only to increase the trouble of joint sealing, unpacking, tear the sticky tape and inevitably take away the leatheroid on surface, influence the intensity of carton, shorten the life of carton, be unfavorable for the reuse of carton.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defect that the existing carton is unfavorable for repeated use, and provides a carton capable of being folded and recycled quickly.

The technical scheme adopted by the utility model is a carton capable of being quickly folded and recycled, the length of a sheet is the width of the circumferential length and the side edge sealing of the carton, two sides of the sheet are inwards opened along the length direction of the carton, and a middle box body, a lower sealing bottom and an upper side tongue of the carton are separated, and the carton is characterized in that: the heights of the upper side tongues are equal, and the upper edges of the same sides of the four upper side tongues are provided with a lap joint.

Because the carton is in standard stacking process, the upper end of the carton does not bear the weight of the internal objects (namely, the gravity of outward expansion is avoided), and the upper end of the carton only needs to be smooth, so that stacking and effective sealing are not influenced, and dust and foreign objects are prevented from entering the carton. The utility model improves the upper side tongues on the structure of the existing carton, the overlapping openings are formed on the upper side tongues, when the upper end of the carton is closed, four sides can be fixed in a sequential pressing mode, after the first upper side tongue is pressed down, the complete side of the adjacent upper side tongue does not need to bend the first upper side tongue, the upper side tongues can enter the lower part of the first upper side tongue along the overlapping openings of the first upper side tongues and are pressed on the first upper side tongue, the four upper side tongues are sequentially inserted and fixed, the fixing by adhesive tapes is not needed, the disassembly and the assembly are convenient, the number of times of the repeated use of the carton is large, and the repeated use of a turnover box or a standard packaging box is facilitated.

The lap joints have the same size and are convenient to manufacture.

The lap joint opening is an isosceles right triangle.

The length of the upper side tongue is longer than the height of the upper side tongue, and the side length of the isosceles right triangle is equal to the height of the upper side tongue.

The side banding design have the socket, the other end of sheet has the inserted sheet with socket matched with. The side sealing edges are fixed by a stapler or glue at present, and the side sealing edges are movably matched and fixed by the inserting holes and the inserting pieces, so that the whole carton is assembled and disassembled.

The side edge banding is designed with 2 sockets.

The inserting piece is made of an aluminum sheet or a copper sheet, and one inserting piece is provided with two separated leaves.

The design of side banding has 2 sockets at least, the inserted sheet cut trilateral in the department that corresponds of socket by the other end of sheet, remain the rectangular that one end sheet meets, the width of inserted sheet is less than the socket width, the length of inserted sheet is greater than the thickness that socket length adds the sheet, the inserted sheet is buckled after stretching out by the socket.

The carton packaging box is free from being fixed by an adhesive tape, the adhesive tape is saved, the carton packaging box is convenient to disassemble and assemble, the upper cover is tightly sealed, the number of times of repeated use of the carton is large, the recycling of a turnover box or a standard packaging box is facilitated, and the carton packaging box is energy-saving and environment-friendly.

Detailed Description

The utility model is described in detail below with reference to the drawings

Embodiment 1, as shown in fig. 1 and 2, a carton capable of being folded and recycled quickly is characterized in that an upper side tongue 1 is improved on the existing carton structure, the length of a sheet is the width of a peripheral edge of the carton and a side sealed edge 4, two sides of the sheet are opened inwards in the length direction of the carton, a middle box body 3, a lower sealed bottom 2 and the upper side tongue 1 of the carton are separated, the heights of the upper side tongues are equal, a lap joint 11 is designed on the upper edge of the same side of four upper side tongues, the lap joints are the same in size and are isosceles right triangle. For cartons in which the length of the upper side tongue is longer than the height of the upper side tongue, the side length of the isosceles right triangle is generally equal to the height of the upper side tongue. The rest of the parts which are not described are the same as the prior art.

Example 2, as shown in figures 3, 4 and 5, to better illustrate the connection of the side seals to the side fixing edges, the carton is made transparent in figure 5, the side seals are designed with insertion openings 41, typically 2 insertion openings for the side seals or one insertion opening at intervals of 4-8cm, and the other end of the sheet (called the side fixing edge) is fixed with insertion tabs 5 that fit into the insertion openings, in this case the opening 31 is designed through the side fixing edge. The inserting pieces are strip-shaped and made of flexible materials such as aluminum sheets or copper sheets, one inserting piece is folded in half to form two sub-leaves, the sub-leaves penetrate through the opening 31 respectively and then enter the side edge sealing socket 41 to be bent towards two sides, and two ends of the carton sheet are fixed. The rest of the composition which is not described is the same as that of example 1.

Embodiment 3, as shown in fig. 6, the side edge sealing design has at least 2 insertion openings, the insertion sheet is formed by cutting three edges at corresponding positions of the insertion openings from the side fixing edges of the sheet materials, a long strip connected with one end of the sheet material is reserved, the width of the insertion sheet is smaller than that of the insertion opening 41, the length of the insertion sheet is larger than the length of the insertion opening plus the thickness of the sheet material, and the insertion sheet 5 is bent after extending out of the insertion opening. The two inserting sheets are designed oppositely or reversely, the scheme is simple, but the strength is not as good as that of the embodiment 2, and the rest parts which are not described are the same as that of the embodiment 1.
