Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

The invention provides a novel paper-plastic carton, which comprises: the packaging box 1 is embedded in a rectangular paper-plastic frame 2 at the bottom of the packaging box 1; the packing box 1 comprises a box body 11 and a box cover 12, wherein the box body 11 comprises side plates 111 arranged at two sides and folding parts 112 respectively folded inwards from the side plates 111; the folding part 112 is folded inwards and then abuts against the rectangular paper-plastic frame 2, so that part of the rectangular paper-plastic frame 2 is accommodated in a space formed by the side plate 111 and the folding part 112.

As a further improvement, four sides of the paper-plastic 2 are provided with foldable buffer structures 22, the foldable buffer structures 22 and the paper-plastic main body are provided with clamping corners capable of mutually matching, and the four sides of the foldable buffer structures 22 can be folded and fixed on the paper-plastic main body.

As a further improvement, after the foldable buffer structure 22 is folded and fixed on the paper-plastic main body, the rectangular paper-plastic frame 2 is in a double-layer ladder shape with gradually decreasing height from outside to inside, and the foldable buffer structure 22 forms a high-rise ladder.

As a further improvement, the connecting part of the bottom layer step and the high layer step at the two sides of the rectangular paper-plastic frame 2 is provided with an inserting groove 21, and the turning part 112 is turned inwards and then inserted into the inserting groove 21.

As a further improvement, the width of one side of the rectangular paper-plastic frame 2 is defined as D, wherein the width of the high-rise ladder is 1/3-1/2D; wherein the width of the high step is the height of the collapsible cushioning structure 22; when the width of the high step is less than 1/3D, the height of the foldable buffer structure 22 is too low, the buffer capacity is reduced, and at the same time, the distance between the folding part 112 and the side plate 111 is reduced, and the side surface becomes weak; when the width of the high-rise step is larger than 1/2D, the volume of the packing box is reduced, and the width of the low-rise step is reduced, so that the product is difficult to accommodate. Preferably, the width of the high-rise ladder of the product is 5/12D.

In order to verify whether the novel paper-plastic carton A can better cope with the impact action in the distribution process compared with the traditional pizza box B, three groups of experiments for carrying out impact tests on six surfaces of a packing box are respectively completed in each group. And the mounting position of the accelerometer is positioned at the geometric center of the side surface of the packing box in the testing direction.

Wherein, novel carton A test environment is moulded to paper does: the falling height is 76cm, the weight of the product is 5.65Kg, the weight of the packaged product is 7.79Kg, the weight of a power line is 0.17Kg, the weight of a VGA line is 0.12Kg, the weight of a plastic bag is 0.02Kg, the weight of a shock absorption member is 0.84Kg, the weight of a carton is 0.99Kg, the external dimension of the packaged product is 625 x 425 x 175mm, the filtering frequency is 5000Hz, and a half sine wave is simulated in an impact response spectrum software.

Wherein, the traditional pizza box B test environment is as follows: the falling height is 76cm, the weight of the product is 5.65Kg, the weight of the packaged product is 7.99Kg, the weight of a power line is 0.17Kg, the weight of a VGA line is 0.12Kg, the weight of a plastic bag is 0.02Kg, the weight of a shock absorption piece is 0.84Kg, the weight of a carton is 1.185Kg, the external dimension of the packaged product is 650 x 425 x 195mm, the filtering frequency is 5000Hz, and a half sine wave is simulated in an impact response spectrum software.

Table 1 is the experiment back, and the comparison of impact response spectrum acceleration value G value, wherein novel paper plastic carton A's G value is obviously less than traditional pizza box B is the G value under same experimental condition, compares under novel paper plastic carton's shock resistance is stronger.

TABLE 1

After the test, the function, the machinery and the safety factor are checked without any problem; the package vibration test is passed; the package drop test passed. The experimental result shows that, according to the invention, as the folding part 112 is folded inwards and props against the rectangular paper-plastic frame 2, so that part of the rectangular paper-plastic frame 2 is accommodated in the space formed by the side plate 111 and the folding part 112, the strength of the paper boards on two sides of the packing box is improved, and compared with the traditional pizza box, the shock resistance of the invention on each side of the paper box is stronger; meanwhile, the whole volume of the packing box is reduced by about 13.7%, the whole weight is reduced by about 2.5%, the occupied space and the transportation cost are reduced, and a large amount of manpower and material resources are saved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
