Description

A multifunctional packaging carton

technical field

The utility model relates to a packing carton, in particular to a multifunctional packing carton, which belongs to the technical field of packing.

Background technique

With the rapid development of the transportation industry, the market demand for packaging boxes is increasing, and the requirements for packaging boxes are also getting higher and higher: not only must they have sufficient strength, but they must also be environmentally friendly, simple in structure, and easy to use. Although the original wooden packaging boxes have high hardness and strength, they require many wooden resources and high production costs. Therefore, paper packaging boxes (referred to as cartons) came into being. Cartons can be used to pack light weight items such as clothes, food, cosmetics, etc., and can also be used to pack heavy items such as TV sets and refrigerators. , low price, can also be recycled, green and environmentally friendly, deeply loved by people.

At present, the structure of most cartons on the market is: the bottom of the carton, the sides of the carton and the top of the carton are connected as one, the top of the carton is a movable cover, and the side of the carton is connected as one and can be folded. Cardboard folded into a cuboid or cube. For example, the Chinese utility model patent with the authorized announcement number CN204368589U discloses a kind of express packaging carton, which includes a front side panel, a left side panel, a rear side panel and a right side panel. On the side wall of the box body, the bottom edges of the four side panels respectively extend out to overlapped bottom panels. The carton with this structure can make the bottom plates automatically flatten into the bottom of the box under the traction of the side plates when the side plates are unfolded. There is a structure for people to hold, which makes it easy to slip and damage items during the process of carrying the carton.

Utility model content

Aiming at the above shortcomings, the technical solution adopted by the utility model is to provide a multi-functional packaging carton with strong structure, high strength and convenient use.

In order to solve the above problems, the utility model is realized through the following technical solutions:

A multi-functional packaging carton, including a box body, the box body includes a plurality of side panels connected in sequence to form the side wall of the box body, a bottom panel is connected to the bottom of each side panel, and a movable panel is connected to the top of each side panel. The box cover is vertically provided with reinforcement columns on each corner of the box body, and correspondingly provided with slots for fixing the reinforcement columns on the bottom plate; at least one group of symmetrical side panels are provided with gripping grooves on the outer surface.

In the above solution, in order to further improve the strength of the carton bottom plate and the anti-compression and cushioning function, the bottom plate is mainly composed of a core paper layer, a buffer anti-pressure layer, a corrugated paper layer and a kraft paper layer from top to bottom.

In the above solution, in order to improve the waterproof and moisture-proof effect of the carton, a layer of waterproof material can be coated on the inner and outer surfaces of the bottom plate and the side plates.

In the above solution, the buffering pressure-resistant layer can be formed by bonding and compounding 2 to 7 layers of honeycomb paper layers.

In the above solution, the reinforcing column may specifically be any one of L-shaped wooden strips, composite paper pallets, and PE plastic boards.

The beneficial effects of the utility model are:

The utility model can effectively improve the strength of the packaging carton and the buffering and anti-compression effect through the designed structure of the reinforcing column, the slot and the bottom plate; It is more convenient; the waterproof material layer coated on the inner and outer surfaces of the side panels and the bottom panel can avoid the damage of the packaging carton due to factors such as moisture and water. Compared with the traditional structure of the packaging carton, the utility model has a simple structure , high strength, good compression resistance and cushioning, and easy to hold and carry.

detailed description

The utility model is further explained below in conjunction with specific embodiments and accompanying drawings, but it is not intended to limit the utility model, and the "multi-block" involved in the utility model specifically refers to more than 3 (including 3) For "many" block, "many" number.

As shown in Figure 1, a kind of multifunctional packaging carton comprises a box body 1, and the box body 1 includes a plurality of side panels connected in sequence to form the side walls of the box body, and a base plate 4 is connected to the bottom of each side panel, the The connection mode between the bottom plate 4 and the side plates can be specifically a hinge mode or a fixed connection mode with fasteners such as nails. The top of each side plate is connected with a movable case cover 2, and the movable case cover 2 is connected with the side plate as a whole, and creases are provided at the junction of the side plate and the movable case cover 2. Creases for turning over are provided between the side panels, so that the side panels are connected as a whole, and together with the bottom panel 4 constitute a box body 1 with a storage space.

Reinforcing columns 3 are vertically provided on each corner of the box body 1 , and slots 5 for fixing the reinforcing columns 3 are correspondingly provided on the bottom plate 4 . In this embodiment, the reinforcing column 3 is specifically any one of L-shaped wooden strips, composite paper pallets, and PE plastic boards. As shown in FIG. 2 , the slot 5 used in conjunction with the reinforcing column 3 is also an L-shaped structure. Of course, the reinforcing column 3 may also be an L-shaped angle steel or an L-shaped structure made of other materials.

In order to facilitate the grasping of the box body 1 during transportation, gripping grooves 10 are provided at least on the outer surfaces of a group of symmetrical side plates.

As shown in FIG. 3 , the bottom plate 4 is mainly composed of a core paper layer 6 , a cushioning and anti-pressure layer 7 , a corrugated paper layer 8 and a kraft paper layer 9 from top to bottom and is bonded and laminated by heat and pressure. In this embodiment, the buffering and anti-pressure layer 7 is formed by bonding and compounding 2 to 7 honeycomb paper layers. The core paper layer 6 is formed by bonding and compounding more than 3 layers of corrugated paper, and the corrugated paper layer is formed by bonding and compounding 5-8 layers of corrugated paper.

Both the inner and outer surfaces of the bottom plate 4 and the side plates are coated with a waterproof material layer, and the waterproof material layer is specifically existing conventional waterproof glue and waterproof paint.

When the multifunctional packaging carton of this structure is in use, the side panels, the bottom panel 4 and the movable box cover 2 are installed to form a box body 1 with a storage space, and then the L-shaped reinforcing column 3 is inserted into the slot provided on the bottom panel 4 5. Finally, load the items that need to be packaged, and seal and pack them; of course, according to the packaging requirements of the items, you can also choose not to load the reinforcement column 3 (for example, some light-weight and non-fragile items) when packaging, and the use of the reinforcement column 3 More flexible.
