SUMMERY OF THE UTILITY MODEL

Based on the problem, the utility model provides a unsettled buffering formula carton cut-parts only needs single cut-parts, cooperates the sola elastic membrane, can fold into the case, plays the cushioning effect to content, convenient production and use.

For convenience of description, in the following definition of the direction of the cut segment portion, the direction in which the left side panel extends outwardly is left, the direction in which the right side panel extends outwardly is right, and the direction in which the front side panel extends outwardly is front, and vice versa, from the bottom panel as a reference position with the cut segment in a flat state as a reference view. This directional definition is only used to introduce the present solution herein. Also, the definition of the direction is not exclusive and therefore does not limit the present disclosure to any other suitable direction. Furthermore, to the cut-parts of this scheme along the symmetry axis that the fore-and-aft direction is placed in the middle, symmetry axis bilateral symmetry. For economy of space, hereinafter, referring to the symmetrical structure, only one side of the axis of symmetry will be described in detail, and the description of the other side will be omitted.

In order to realize the purpose of the invention, the utility model adopts the following technical scheme: the utility model provides a unsettled buffering formula carton cut-parts, is equipped with the preceding curb plate that the shape is the rectangle, and preceding curb plate connects gradually roof, posterior lateral plate and the bottom plate of aequilate on length direction, still extends on the length direction of bottom plate to be connected with the buffer board, and the length of buffer board is not less than the length of bottom plate, and the width is not more than the width of bottom plate.

This technical scheme design's unsettled buffering formula carton cut-parts, on traditional carton cut-parts can encircle the structure basis of the preceding curb plate of round, roof, posterior lateral plate and bottom plate, still extend on the length direction of bottom plate and be connected with the buffer board.

Preferably, the buffer plate is provided with an elastic membrane tensioning structure. The elastic film is fixed and tensioned to cover the back surface of the cushion plate, and the specific structure is also adopted in many cases, for example, bonding, clamping, nailing and the like, and the elastic film is only required to be tensioned so that the contents can be fixed on the cushion plate. The skilled person can select it as desired.

Preferably, the elastic membrane tensioning structure is: a buffer plate backward bending plate is connected in an extending manner in the length direction of the buffer plate, the length of the buffer plate backward bending plate is not more than that of the rear side plate, and the width of the buffer plate backward bending plate is not more than that of the buffer plate; the two sides of the buffer plate in the width direction are respectively connected with a buffer plate right bending plate and a buffer plate left bending plate in an extending manner; the right secondary bending plate is arranged on the buffer plate and extends towards the free end of the buffer plate rear bending plate, and the inner side edge of the right secondary bending plate is connected with the right side edge of the buffer plate rear bending plate; the left bending plate of the buffer plate extends towards the free end of the rear bending plate of the buffer plate to form a left secondary bending plate, and the inner side edge of the left secondary bending plate is connected with the left side edge of the rear bending plate of the buffer plate. The elastic membrane tensioning structure that this scheme provided designs the bending plate that can buckle respectively for the both sides and the rear at the width direction of buffer board, with the whole covering of elastic membrane on buffer board and outlying bending plate, the bending plate of aforementioned three orientation of bending after putting into the content, with the whole tensioning of elastic membrane can. Thus, another advantage of this solution is that only one elastic film is needed.

Preferably, a right side plate and a left side plate are connected to both sides of the bottom plate in the width direction in an extending manner. In this scheme, the width direction both sides at the bottom plate are connected to right side board and left side board, and the width is the same with the length of preceding curb plate, posterior lateral plate, and the side direction is sealed about becoming the carton after the case.

Preferably, the free end of the right side plate extends and is connected with a right side top turning plate in the width direction; the free end of the left side plate extends and is connected with a left side top turning plate in the width direction. The right side top flap and the left side top flap are folded upwards when in use to form a support for the edges of the top flaps, which is helpful for maintaining the shape of the carton.

Preferably, the joint of the right side plate and the right side top turning plate and the joint of the left side plate and the left side top turning plate are both provided with positioning insertion joints in a penetrating way; correspondingly, the top plate is provided with positioning insertion pieces extending from both sides in the width direction; the positioning insertion pieces and the positioning insertion joints are in one-to-one correspondence to form an insertion structure. The inserting structure is used for fixing the top plate, the left side plate and the right side plate.

Preferably, a hand hole is provided through the other surface of the front side plate in the longitudinal direction. Design hand hole makes things convenient for the finger to stretch into the carton, lifts the preceding curb plate to open the carton. The hand hole can be a round hole, a semicircular hole or other shapes, and the position can be close to the front end of the front side plate or the middle part of the front side plate and can be designed by the skilled person as required.

Preferably, the connecting part of the bottom plate and the buffer plate is provided with a hand hole shielding piece extending towards the direction of the buffer plate, the position of the hand hole shielding piece corresponds to the position of the hand hole, and the size of the hand hole shielding piece is larger than that of the hand hole. The hand holes, while convenient for opening the carton, leave a void in the front panel that disrupts the closure of the carton. Therefore, the hand hole shielding piece is designed, is not completely folded along with the buffer plate, is bent to be parallel to the front side plate, and is shielded inside the hand hole after being formed into a box so as to keep the sealing performance of the carton.

Preferably, the side edge of the right side plate facing the front plate direction is connected with a right side plate rear connecting plate in an extending manner, and the side edge of the left side plate facing the front plate direction is connected with a left side plate rear connecting plate in an extending manner; the length of the right side plate rear connecting plate and the left side plate rear connecting plate is not more than that of the rear side plate.
