In particular, the corrugated carton packaging used for packaging lightweight items on the market is still glued with adhesive tape. The extensive use of adhesive tape is not conducive to the subsequent recycling of cartons, and also causes soil pollution.

Utility model content

The purpose of this utility model is to solve the following shortcomings in the prior art. The packaging of corrugated cartons on the market is still bonded by adhesive tape. The extensive use of adhesive tape is not conducive to the recovery of subsequent cartons, and also causes soil pollution. And propose a kind of glue-free corrugated box.

In order to achieve the above object, the utility model adopts the following technical solutions:

An adhesive-free corrugated box, comprising a plurality of side plates enclosing a rectangular space, both ends of each of the side plates are integrally formed and rotatably connected with a sealing plate, and each of the sealing plates is provided with a plurality of The friction cardboard and the plurality of friction grooves, the friction cardboard and the friction grooves on the two opposite sealing plates can match each other, that is, the friction cardboard is detachably connected in the corresponding friction groove.

Preferably, the cross-sectional area of the friction paperboard is larger than that of the friction groove.

Preferably, a plurality of reinforcing ribs are connected to the inner side wall of the side plate, and each of the reinforcing ribs is hollowly arranged up and down.

Preferably, a fastening belt is sheathed on the outer side wall of the side plate.

Preferably, an observation slot is opened on the side wall of the side plate, and a transparent observation window is installed on the observation slot.

Preferably, a slot is opened in each of the friction cardboards, and an auxiliary cardboard is installed in the slots.

Compared with the prior art, the beneficial effects of the utility model are:

Through the non-smooth treatment of the surface of the friction cardboard, multiple friction cardboards can be inserted into the friction groove to superimpose the friction force, so that the packaging can be carried out without using adhesive tape, reducing the utilization rate of adhesive tape, and avoiding the use of adhesive tape to a certain extent. Pollution.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

Terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in the utility model are only for convenience of description, and are not used to limit the utility model. The applicable scope of the new utility model and the change or adjustment of its relative relationship shall also be regarded as the applicable scope of the utility model if there is no substantive change in the technical content.

Referring to Figures 1-3, an adhesive-free corrugated box includes a plurality of side panels 1 enclosing a rectangular space. 3 is provided with a plurality of friction cardboards 5 and a plurality of friction grooves 4, the plurality of friction cardboards 5 and the friction grooves 4 can be arranged in an array or irregularly, and the surface of the friction cardboard 5 is not smoothed, it is a belt For cardboard with rough edges, the friction cardboard 5 and the friction groove 4 on the two opposite sealing plates 3 can match each other, that is, the friction cardboard 5 is detachably connected in the corresponding friction groove 4, and the friction cardboard on the facing cover plate 3 5 and friction groove 4 are misplaced settings. When packing light objects, including plastic parts, children's toys, books, and light-weight express items, when packaging is required, the two opposite sealing plates 3 are folded, and then the friction cardboard 5 is inserted into the corresponding friction groove 4, and the friction force between multiple friction cardboards 5 and the friction groove 4 is used, so that the two friction grooves 4 are not separated, and when the friction groove 4 is squeezed by the goods, it is As the force increases, its friction also increases, further increasing the degree of stability.

The cross-sectional area of the friction cardboard 5 is greater than the cross-sectional area of the friction groove 4, and the corrugated cardboard box has toughness and can be further compressed. The friction cardboard 5 can be inserted into the friction groove 4. Slight recovery, thereby increasing the frictional force between the friction cardboard 5 and the friction groove 4.

A plurality of reinforcing ribs 7 are connected to the inner side wall of the side plate 1, and each reinforcing rib 7 is hollowly arranged up and down, and the reinforcing ribs 7 can increase the firmness of the entire carton. When squeezed, it acts as a buffer.

The outer wall of the side plate 1 is also covered with a fastening belt 2, which can play the role of wrapping inwards, and when the fastening belt 2 is put on, it can be placed on one side of the package, which further increases the stability , to avoid excessive deformation of the side plate 1 caused by the extrusion of items, which will affect the packaging effect.

An observation slot is provided on the side wall of the side plate 1, and a transparent observation window 6 is installed on the observation slot. The observation window 6 can be used to initially observe the condition of the articles in the packing box, which can be used for monitoring at any time.

Each friction cardboard 5 is provided with a slot, and an auxiliary cardboard 8 is installed in the slot. The auxiliary cardboard 8 can increase the hardness of the entire friction cardboard 5, avoid deformation in the friction groove 4, and increase the difficulty of insertion.

In the present utility model, terms such as "installation", "connection", "connection" and "fixation" should be interpreted in a broad sense unless otherwise specified and limited.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. The equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
