Fig. 1 illustrates an expanded view of a variable volume carton according to an embodiment of the present application. As shown in fig. 1, 2 and 3, the variable volume carton comprises: a box board main body 100; the box main board 100 includes: side panels 110, a cover panel 120, and a bottom panel 130.

The box board main body 100 is provided with a first pressing line 101, a second pressing line 102 and a third pressing line 103 in parallel in the lateral direction thereof; the first pressing line 101 or the second pressing line 102 is divided into a side plate and a cover plate, and the third pressing line 103 is divided into a side plate 110 and a bottom plate 130.

The trunk board main body 100 is provided with a plurality of folding lines 104 in parallel in a longitudinal direction thereof to divide the side panels 110, the cover panel 120, and the bottom panel 130 into a plurality.

By folding the box panel body 100 along the first or second

pressing line

101 or 102, the third pressing line 103, and the folding line 104, a carton having different heights can be formed.

When the carton is folded into a carton with larger height, the carton cover is folded inwards along the first pressing line 101, and the two cover plates 120 at the opposite sides can just seal the top of the carton 100; when the carton is folded into a carton with smaller height, the carton cover is folded inwards along the second pressing line 102, the two cover plates 120 at the opposite sides are mutually overlapped, and the overlapping length depends on the distance between the first pressing line 101 and the second pressing line 102; when folded inwardly along the first press line 101, the bottom area of the carton is unchanged but the height thereof is reduced than when folded inwardly along the second press line 102, so that the overall volume of the carton is reduced and the length of the cover panel 120 is increased.

In one possible implementation, there are four side plates 110, four cover plates 120 and four bottom plates 130, where the four cover plates 120 have the same longitudinal length, the four bottom plates 130 have the same longitudinal length, and corners of the four cover plates 120 and the four bottom plates 130, which are not connected to the side plates 110, are rounded.

In one possible implementation, there are slots 105 between the four cover plates 120; gaps 105 are formed among the four bottom plates 130; the length of the slit 105 is equal to the length of the longitudinal side of the cover plate 120 or the base plate 130.

In one possible implementation, when the carton board body 100 is folded along the first pressing line 101, the height of the carton is the distance from the first pressing line 101 to the third pressing line 103, and the slit 105 extends to the first pressing line 101.

In one possible implementation, when the carton board body 100 is folded along the second pressing line 102, the height of the carton is the distance from the second pressing line 101 to the third pressing line 103, and the slit 105 extends to the second pressing line 101.

In one possible implementation, the side plates 110, the cover plate 120, and the base plate 130 are all square structures; after the folding forming, the carton is of a cuboid structure with a hollow interior.

In one possible implementation, an adhesive edge 111 is connected to a longitudinal edge of one side of the side plate 110, and the adhesive edge 111 can be attached to an inner wall of the longitudinal edge of the opposite side of the side plate 110.

In a possible implementation manner, the adhesive edge 111 is trapezoidal, and the long bottom of the adhesive edge 111 is connected with the side plate 110 and has a length less than or equal to the longitudinal length of the side plate 110.

In a possible implementation manner, the sum of the length of the longitudinal edge of the cover plate 120 and the length of the second pressing line 102 from the top of the side plate 110 is less than the length of the transverse edge of the side plate 110; the length of the longitudinal edge of the cover plate 120 is greater than the length from the second pressing line 102 to the top of the side plate 110, the box can be a cuboid and has no redundant protruding edge in the using process, the whole sealing performance of the carton is better by packaging, and the carton is more tidy when being stored and put.

It should be noted that although a variable volume carton is described above by way of example, those skilled in the art will appreciate that the present application is not so limited. In fact, the user can flexibly set the size and the material of the carton according to personal preference and/or practical application scenes, and only the requirement that the size of the carton can be adjusted according to the size of a product is met.

Like this, through setting up three lines of pressure on the carton, divide into apron, curb plate and bottom plate with the carton, can adjust the proportion of carton curb plate and apron as required, reach the purpose of adjusting the carton height to change the carton volume, when packing less size article, reduce the inside vacant space of carton, can material saving when fixing the product, and the whole occupation space of carton still less.

Having described embodiments of the present application, the foregoing description is intended to be exemplary, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen in order to best explain the principles of the embodiments, the practical application, or improvements to the technology in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
