Description

Binding-free folding self-sealing packaging cartons

technical field

The utility model relates to a packing carton, in particular to a binding-free folding self-buckle-sealing packing carton used for packing and transporting fruits, vegetables and the like.

Background technique

Carton is one of the most commonly used packaging supplies, which is used for packaging and transportation of various items. Because of its environmental protection and breathable characteristics, it is also widely used for packaging and transportation of fruits and vegetables. The current packaging cartons are usually made of corrugated cardboard, which are cut according to the geometric dimensions of the four sides of the carton, the interface, and the structure of the upper and lower box covers, and then pressed to remove marks, folded, and bound to form a carton. The interface is generally used with iron nails binding. In order to facilitate transportation, the finished cartons are bound and formed, and then folded flat before leaving the factory. This kind of carton, because the thickness of the interface double-layer cardboard plus iron nails is quite different from the thickness of the box body and the upper and lower box covers, it not only brings inconvenience to storage and transportation, but also increases transportation costs; After the product is loaded, it needs to be sealed with sealing glue. For packaging and transportation of fruits, vegetables and other products, it is difficult to meet the requirements of green environmental protection, and it will also form white pollution.

Contents of the invention

The technical problem to be solved by the utility model is to provide a binding-free folding and self-sealing packaging carton. The packaging carton not only does not need binding, but also does not need to be boxed before use, which is convenient for transportation, and can be self-sealing with its own structure.

The technical solution adopted by the utility model to solve the technical problem is: the binding-free folding self-closing sealing packaging carton is made of cardboard cutting, pressing creases, and folding. The cover plate has indentations at the joints of each plate. The horizontal sides of the bottom plate are provided with a first side plate and a folded plate. Both ends of the folded plate are provided with folded plates. The longitudinal sides of the bottom plate are provided with a second side plate And the cover plate, the two ends of the second side plate are provided with connecting plates, the folded back plate and the folded plate are bent in the box, and the connecting plate is sandwiched together with the first side plate, and the first side plate intersects the edge with the folded plate There are clamping holes for the cover plate, and the clamping buckles provided at both ends of the cover plate are engaged with the clamping holes on the first side plate. When using this kind of packaging carton, there is no need to form a box before use. It is quite a piece of unfolded cardboard, which does not occupy extra space and is convenient for transportation.

As an improvement of the utility model, a longitudinal card slot is provided on the surface of the bottom plate, so as to be used for connecting with the folded back plate.

As another improvement of the utility model, a longitudinal clamping flange is provided on the edge of the folded back plate, and the longitudinal clamping flange is clamped into the longitudinal clamping groove on the bottom plate. When this structure is adopted, since the folded plate and the bottom plate are connected together, the second side plate is more tightly connected into one body, so the box body is stronger and more stable.

The beneficial effects of the utility model are:

1. The structure is extremely simple, free of binding. Since the packaging carton of the present invention is integrated through the mutual clamping and connection between the side panels, it can not only avoid binding, is strong and stable, but also easy to install and use.

2. Reduce transportation costs. Since it does not need to be boxed before use, it does not take up extra space in transportation, which can greatly reduce transportation costs.

3. Using its own structure to self-tighten and seal, it is more in line with the environmental protection requirements of packaging and transportation of fruits, vegetables and other products, and avoids white pollution caused by the use of sealing glue and increases transportation costs.

Detailed ways

See Figure 1 and Figure 2, the binding-free folding self-sealing packaging carton is made of corrugated cardboard cutting, pressing creases, and folding. There are indentations, and the second side plate 8 and the cover plate 9 are provided with vent holes 11, so that the carton can be ventilated through the vent holes 11 when packing and transporting fruits and vegetables, which is convenient for freshness preservation. The central part of the first side plate 2 A hand hole 13 is provided, which is convenient for carrying the carton. The lateral sides of the base plate 3 are provided with a first side plate 2 and a folded plate 4. The two ends of the folded plate 4 have a folded plate 6. The longitudinal sides of the base plate 3 are provided with There is a second side plate 8 and a cover plate 9, the two ends of the second side plate 8 are provided with connecting plates 7, the folded plates 4 and 6 are bent in the box, and the connecting plates 7 are clamped together with the first side plate 2 In the middle, on the edge where the first side plate 2 intersects with the folded plate 4, there is a snap-fit hole 12 of the cover plate, and the snap-fit buckles 10 provided at both ends of the cover plate 9 are engaged with the snap-fit holes 12 on the first side plate 2 The diameter of the buckle 10 is slightly larger than that of the hole 12, so that it is tightly connected. The plate surface of the base plate 3 is provided with a longitudinal clamping groove 1, and the edge of the folding back plate 4 is provided with a longitudinal clamping flange 5, and the longitudinal clamping flange 5 is clamped into the longitudinal clamping groove 1 on the base plate, so that the folding back The board 4 and the bottom board 3 are connected together, so that the second side board 8 is more tightly connected into one body, so the box body is stronger and more stable.

In order to facilitate storage and transportation, the packaging carton of the present invention can be kept in a flat state before use, and then folded into shape when used.
