Technical Field

The utility model belongs to the carton packing field specifically is a convenient uncovered case cut-parts that piles up.

Background

The carton is common packing thing, has multiple shape, and what this scheme was discussed is the carton that has the rectangle lateral wall of a plurality of heights. In a common carton, a box cover is arranged above a box body. The box cover has the second function, namely, the box body is closed, and the platform is formed above the box body, so that a plurality of cartons with the same specification can be conveniently and longitudinally stacked. There are some cartons, and the main function is for the show, therefore the box top is open design, does not design the case lid. The problem with this is that it is very difficult to stack the same size cartons longitudinally due to the lack of a top platform. In order to solve the problem, a common method is to rotate the upper and lower layers of cartons around the longitudinal axis of the stack for a certain angle to form dislocation and then stack the cartons. The treatment mode has two problems, firstly, the weight of the upper layer carton is only born by partial side walls of the lower layer carton, so the side walls of the lower layer carton are easy to deform under pressure; and secondly, the longitudinal whole row of cartons is uneven, which is not only beneficial to saving space, but also beneficial to storage and transportation operation.

SUMMERY OF THE UTILITY MODEL

In order to realize the purpose of the invention, the utility model adopts the following technical scheme: an open box cutting piece convenient to stack comprises a plurality of rectangular side plates, wherein each side plate is equal in height, adjacent side plates are connected through a longitudinal crease line, a bottom structure is connected below each side plate, and an inward pushing structure is arranged between each two adjacent side plates; the inner pushing structure is as follows: a left oblique crease line extending in the upper left-lower right direction is arranged at the upper right corner of the left side plate, and a right oblique crease line extending in the upper right-lower left direction is arranged at the upper left corner of the right side plate; the left oblique crease line and the right oblique crease line are intersected at a point on the longitudinal crease line; on the left side plate, a left oblique crease line, a longitudinal crease line and the upper side edge of the left side plate are enclosed to form a left inner pushing area; on the right side curb plate, right oblique crease line, vertical crease line and right side curb plate upper flank enclose and form the right side and push away the district.

The convenient open case cut-parts that piles up of this technical scheme design refers to the overall arrangement structure of 0201 carton, and the top is the round curb plate, and folding surrounds the lateral wall that constitutes the carton after, and the below is bottom structure then. The side plates are all rectangles with equal height, so that the section shape of the carton related to the scheme can be triangular, rectangular or polygonal in other forms, the lengths of the sides are not required to be equal, and the carton is specifically determined by design requirements. The underlying base structure can be a conventional structure such as the 0201 carton base structure, can be a lock base structure popular in the time, or can be selected by those skilled in the art as required by design requirements in the prior art. An inward pushing structure is designed between each two adjacent side plates. Specifically, the upper right corner of the left side plate is provided with a left oblique crease line extending in the upper left-lower right direction, and the upper left corner of the right side plate is provided with a right oblique crease line extending in the upper right-lower left direction. And the left oblique crease line and the right oblique crease line are intersected with the longitudinal crease line at a point. From this, on the left side curb plate, the side encloses and forms left side pushing in district on left side oblique crease line, vertical crease line and the left side curb plate, on the right side curb plate, the side encloses and forms right side pushing in district on right side oblique crease line, vertical crease line and the right side curb plate. When the folding box is folded, the left inner pushing area and the right inner pushing area are pushed to be sunken towards the inner direction of the box, so that the upper side edges of the two adjacent side plates are changed into broken lines from straight lines, and the whole inner pushing structure forms a tetrahedron in space. After each of the pushers is operated in the same manner, the top surface of the carton forms a virtual top surface formed by each of the pushers, which top surface can then be used to stack longitudinally to carry the upper carton. Each surface of the tetrahedron is triangular, and has very strong pressure resistance in mechanics, so that the load bearing problem can be well solved. Because this design does not need the carton axial rotation, consequently the horizontal pile up of carton also can be very compact, has practiced thrift the space.

Preferably, the outer side surfaces of the left inner pushing area and the right inner pushing area are provided with fixing structures which are tightly attached to each other. The fixing structure may be a paste or a nail, for example, a double-sided tape is used to closely adhere the outer side surfaces of the left and right pushing-in areas when the box is folded. This has the effect of preventing the tetrahedron formed by the push-in structure from loosening.

Preferably, the bottom structure is each lower rocking cover connected to the lower side of each side plate respectively; a positioning convex tongue is convexly arranged on the upper side edge of the side plate upwards, and a positioning hole is correspondingly arranged on the lower side edge of the side plate and communicated with the connecting part of the lower rocking cover; the positioning convex tongue and the positioning hole are in adaptive splicing relation. When the upper layer box and the lower layer box are stacked, the positioning holes of the upper layer box are sleeved outside the positioning convex tongues of the lower layer box to form a positioning effect, and the longitudinal stacking is tidy. The matching relationship between the positioning convex tongue and the positioning hole can be arranged on each side plate, and can also be arranged on the side plate at the opposite position, and the matching relationship can be selected by the skilled person according to the needs.

To sum up, the beneficial effects of the utility model are that: the folded open box can be conveniently and orderly longitudinally stacked.
