Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a cardboard lining for packaging boxes. Background Art

[0002] As the name suggests, packaging boxes are boxes used to package products. They can be classified by material, such as paper boxes, iron boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated boxes, etc. They can also be classified by product name, such as moon cake boxes, tea boxes, wolfberry boxes, candy boxes, exquisite gift boxes, local specialty boxes, wine boxes, chocolate boxes, food and medicine health product boxes, food packaging boxes, tea packaging boxes, pencil cases, etc. The function of packaging boxes is to ensure the safety of products during transportation and improve the grade of products. The lining of the packaging box plays the role of positioning items in the packaging box.

[0003] Chinese patent publication number CN215972878U discloses a packaging box lining structure comprising a plurality of vertical and horizontal strips, each of which intersects to form a plurality of honeycomb-shaped compartments, each of which can accommodate an item. This utility model, by forming multiple compartments, allows for the placement of multiple items within the packaging box, ensuring that each item is well positioned and prevents collision.

[0004] Although the above-mentioned packaging box lining structure can form a plurality of compartments for placing a plurality of items in the packaging box, and each item can be well positioned without colliding with each other, the lining structure generally needs to be made of plastic blister or foam. When the order batch is small, the foam or plastic needs to be molded, resulting in high costs. For this reason, we propose a cardboard lining for packaging boxes. Utility Model Content

[0005] The purpose of the present invention is to provide a cardboard lining for a packaging box, so as to solve the problem raised in the above background technology that since the lining structure generally needs to be made of plastic blister or foam, when the order batch is small, the foam or plastic needs to be molded, resulting in high costs.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a cardboard lining for a packaging box, comprising:

[0007] A box front panel, one side of the box front panel is connected to a box side panel, and the lower part of the box side panel is connected to a box pressing plate, and the lower part of the box front panel is respectively connected to a box bottom panel and a box clamping plate;

[0008] The second box front panel is connected to one end of the first box front panel, one side of the second box front panel is connected to the second box side panel, and the lower part of the second box side panel is connected to the second box clamping plate, the lower part of the second box front panel is connected to the second box bottom panel, and a connecting middle plate is provided between the two box side panels.

[0009] Preferably, the front panel of the box is further provided with:

[0010] A bonding panel is connected to one side of the box front panel.

[0011] Preferably, the width of the front panel of the second box is consistent with that of the front panel of the first box, and the height of the front panel of the second box is less than that of the front panel of the first box.

[0012] Preferably, the connecting middle plate has the same size as the side panels of the second box, and the connecting middle plate is bonded to the front panels of the second box via an adhesive panel.

[0013] Preferably, the bottom panel of the box is engaged with each other through a box pressing plate and a box clamping plate, and the box pressing plates are symmetrically distributed about the vertical center line of the box clamping plates.

[0014] Preferably, the second box bottom panels and the second box clamping plates are clamped with each other, and the second box clamping plates are symmetrically distributed about the vertical center line of the second box bottom panels.

[0015] Compared with the prior art, the present invention provides a cardboard lining for a packaging box, which has the following features:

[0016] Beneficial effects:

[0017] The utility model uses cardboard instead of plastic lining, with a short and fast production cycle. After die-cutting, the box is glued and formed by a machine, and then it can be formed by using indentations and knife seams to clamp it. It solves the problem that small orders require molds for foam, which is high in cost and has a slow production cycle. At the same time, it saves packaging resources, reduces excessive packaging, and is green and environmentally friendly. It avoids the problem that the lining structure generally needs to be made of plastic blister or foam. When the order batch is small, both foam and plastic need to be molded, which leads to high costs. BRIEF DESCRIPTION OF THE DRAWINGS
