Detailed Description

Specific embodiments of the present utility model are described in further detail below. It should be understood that the description herein of the embodiments of the utility model is not intended to limit the scope of the utility model.

Fig. 1 is a schematic structural diagram of a glue-free carton provided by the utility model. The glue-free carton comprises a carton body 10, four outer shaking covers 11 respectively connected with two ends of the carton body 10, and four inner shaking covers 12 respectively connected with two ends of the carton body 10. It is conceivable that the glue free carton further comprises some other functional modules, such as a glue header, a cover, a logo, etc., which are known to the person skilled in the art and will not be described in detail herein.

The box 10 forms a receiving space with two open ends after assembly, and includes a front plate 101, two end plates 102 respectively connected to two ends of the front plate 101, and a rear plate 103 connected to the other side of the two end plates 102. The front plate 101 and the rear plate 103 have the same dimensions such as length, width, and the like. It is conceivable that the front plate 101 and the rear plate 103 may be connected by a glue head, and the fixing manner may be a fastener such as a nail, which is a prior art and is not described herein. It is conceivable that the specific dimensions of the end plate 102 and the front and rear plates 101, 103 should be designed according to practical needs. The case 10 may be made of corrugated board material to increase the strength and shock resistance of the carton, so that the case 10 has the characteristics of light weight, high structural strength and high buffering capacity.

Four of the outer swing covers 11 are provided at both ends of the front plate 101 and the rear plate 103, respectively. The width of the outer swing cover 11 may be half the length of the inner swing cover 12, and the outer swing covers 11 on the same side of the case 10 at two positions may be turned over and combined on a plane perpendicular to the front plate 101 and the end plate 102, i.e. cover as shown in fig. 2. The outer swing cover 11 includes one outer swing cover body 111, and two insertion openings 112 provided on the outer swing cover body 111.

The shape of the outer swing cover body 111 may be rectangular. The socket 112 is rectangular in shape. The direction of arrangement of the two sockets 112 is the same as the direction of arrangement of the two end plates 102. The socket 112 is disposed at a free end of the outer swing cover 11 facing away from the front plate 101 or the rear plate 103, and one end of the socket 112 is open. The distance between the two sockets 112 on each outer swing cover 11 is equal, so that when the outer swing covers 11 are closed, a large socket is formed to be assembled with a plugging part 122, which will be described in detail below.

In the four inner swing covers 12, both ends of each of the end plates 102 are respectively connected to two inner swing covers 12. The inner swing cover 12 includes a receiving portion 121 connected to the end plate 102, and a plug portion 122 connected to the receiving portion 121. The insertion part 122 of the inner swing cover 12 is inserted into a large insertion opening formed by the insertion opening 112 of the outer swing cover 11. The inner swing cover 12 has a smaller size than the outer swing cover 11 in the arrangement direction along the two end plates 102. The area of the inner swing cover 12 on the same side of the box body 10 can be smaller than half of the area of the two ends of the box body 10, so that the consumption materials for manufacturing the paper box can be saved, and the cost is reduced. Of course, the length of the inner swing cover 12 in the direction of the arrangement of the end plates 102 of the case 10 may be reduced according to actual needs, such as bearing capacity.

The receiving portion 121 is connected between the end plate 102 and the insertion portion 122. The shape of the receiving part 121 is rectangular with two right angles cut off on the same side, and the shape of the receiving part 121 is formed simultaneously when the insertion part 122 is cut. The size of the receiving portion 121 is larger than the size of the insertion portion 122 in the arrangement direction along the front plate 101 or the rear plate 103. The shape of the receiving portion 121 at two sides of the plugging portion 122 may be arc-shaped or linear, so that the plugging portion 122 and the receiving portion 121 form a V-shaped structure.

The shape of the insertion portion 122 may be rectangular. The insertion portion 122 is provided on a side of the end plate 102 connected away from the receiving portion 121 where it is located. The plug 122 has the same thickness as the socket 112. The length of the mating portion 122 is twice the length of the receptacle 112. The inner swing cover 12 is an axisymmetric graph, and the symmetry axis of the inner swing cover 12 along the arrangement direction of the front plate 101 and the rear plate 103 is a straight line passing through the midpoint of the connecting line between the bearing part 121 and the end plate 102 and being perpendicular to the end plate 102, so that the arm of force of the outer swing cover 11 on the same side of the box body 10 on the inner swing cover 12 is the same, and therefore, under the condition that the outer swing cover 11 receives the same gravity, the two plugging parts 122 receive the same pressure of the outer swing cover 11 from the same side of the box body 10, the phenomenon of side-by-side weight and side weight damage is avoided, and the service life of the carton is prolonged. When the inserting portion 122 is inserted into the insertion opening 112 of the box 10, the inserting portion 122 bears the weight from the weight in the box 10 so that the inner swing cover 12 and the outer swing cover 11 are mutually pressed, and meanwhile, the inserting portion 122 presses the outer swing cover 11 and is pressed by the goods, so that the inner swing cover 12 and the outer swing cover 11 cannot be scattered, the inserting portion 122 is prevented from sliding off from the insertion opening 112, and the purpose of closing the carton is achieved.

In the process of closing and assembling the tape-free carton, the outer swing cover 11 is turned over first, the inner swing cover 12 is turned over again, then the outer swing cover 11 is pressed towards the inner side of the carton body 10, the receiving part 121 is bent at the same time, until the inserting part 122 is aligned with the inserting opening 112 and inserted into the inserting opening 112, and finally the pressure on the outer swing cover 11 is released, namely the assembly is completed. The outer and inner swing covers 11 and 12 are laid flat on the case 10 under the action of restoring force.

Compared with the prior art, the adhesive tape-free carton provided by the utility model has the advantages that the socket 112 is arranged on the outer shaking cover 11, the bearing part 121 and the inserting part 122 are arranged on the inner shaking cover 12, so that the inserting part 122 can be inserted into the socket 112 by bending the bearing part 121, the outer shaking cover 11 and the inner shaking cover 12 are mutually inserted and fixed together, the outer shaking cover 11 and the inner shaking cover 12 can not be scattered under the condition of no external force, adhesive tape adhesion is not needed when the carton is sealed, the carton can be repeatedly used for a plurality of times, and the environment is protected. Specifically, the sockets 112 disposed on the outer swing covers 11 with different orientations can be combined to form a large socket, the insertion parts 122 bear gravity from the goods in the box 10, so that the inner swing covers 12 and the outer swing covers 11 are mutually pressed, meanwhile, the insertion parts 122 press the outer swing covers 11 and are pressed by the goods, so that the outer swing covers 11 and the inner swing covers 12 cannot be scattered, the insertion parts 122 are prevented from sliding off the sockets 112, the structural strength is improved, the scattering cannot be achieved when the goods are filled in the cartons, and the use requirement that the cartons cannot be scattered after the cartons are covered is met.

The above is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model, and any modifications, equivalent substitutions or improvements within the spirit of the present utility model are intended to be covered by the claims of the present utility model.
