A kind of multifunctional packaging carton
This utility model relates to a kind of Packaging Box, is specifically related to a kind of multifunctional packaging carton, belongs to packing technique field.
Along with the fast development of transport service, the market demand industry of packing crates is increasing, and product is more and more higher to the requirement of packing crates simultaneously: not only to have enough intensity, also wants environmental protection and simple in construction, easy to use.Original wood packing box, although hardness and intensity are higher, but required wooden resource is many, cost of manufacture is high.Therefore, paper packaging box (abbreviation carton) arises at the historic moment, carton can be used for packing the article of the lighter in weight such as clothes, food, cosmetics, may also be used for the article that the weight such as packaging TV set, refrigerator is bigger, not only have wide range of applications, cheap, recycling the most capable of circulation, environmental protection, liked by people deeply.
And it is current, on market, the structure of most carton is: the top of carton bottom, the sidepiece of carton and carton connects as one each other, the top of carton is the case lid of movable turnover, the sidepiece of carton is the cardboard connecting as one and caning be folded into cuboid or square, Chinese utility model patent if Authorization Notice No. is CN204368589U discloses a kind of express delivery Packaging Box, connecing, including being sequentially connected by front side board, left plate, back side panel and right plate, the wall box surrounded, the bottom margin of four blocks of side plates each extends over out the base plate of mutually overlap joint.The carton of this kind of structure is while launching side plate, each base plate automatic open and flat one-tenth box bottom under the draw of side plate can be made, easy to use, simple in construction, but its intensity is low, easily damage in the process of use, and owing to being not provided with the structure gripped for people, make, in carrying carton process, skidding easily occurs, the situation that article landing damages.
Utility model content
For above-mentioned deficiency, the technical solution adopted in the utility model is to provide the multifunctional packaging carton that a kind of rugged construction, intensity are big, easy to use.
For solving the problems referred to above, this utility model is achieved through the following technical solutions:
A kind of multifunctional packaging carton, including casing, described casing includes being sequentially connected with the polylith side plate constituting wall box, connect in the bottom of each side plate and have base plate, it is respectively connected with removable box cover at the top of every side plate, vertically it is provided with reinforcing prop on each corner in casing, base plate is correspondingly provided with the slot for fixing reinforcing prop；At least offer gripping groove at one group of symmetrical side plate outer surface.
Such scheme, for improving intensity and the resistance to compression pooling feature of carton base plate further, described base plate is mainly composited by core paper layer, buffering resistance to compression layer, corrugated layer hot pressing mutually bonding with layers of kraft paper from top to down.
In such scheme, for improving the waterproof and dampproof effect of carton, one layer of waterproof layer can be coated with at the surfaces externally and internally of base plate and side plate.
In such scheme, described buffering resistance to compression layer can be composited by 2～7 layers of honeycomb ply of paper is bonding.
In such scheme, described reinforcing prop is specifically as follows any one in the batten of L-shaped structure, extrusion coating paper pallet, PE plastic plate.
The beneficial effects of the utility model are:
This utility model, by the structure of reinforcing prop, slot and the base plate of design, can be effectively improved intensity and the buffering resistance to compression effect of Packaging Box；And by arranging gripping groove on side plate, be conducive to grabbing by carton, convenient when carrying carton；At the waterproof layer that the surfaces externally and internally of side plate and base plate is coated with, it can be avoided that the Packaging Box damage that factor causes because of humidity, water etc., this utility model, compared with the Packaging Box of traditional structure, has simple in construction, intensity is high, resistance to compression resiliency is good, and is prone to grip the feature of carrying.

Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, this utility model is further explained explanation, but not in order to limit this utility model, and " polylith " related at this utility model specifically refers to, and more than 3 (containing 3) is referred to as " many " blocks, " many " count.
As shown in Figure 1, a kind of multifunctional packaging carton, including casing 1, described casing 1 includes being sequentially connected with the polylith side plate constituting wall box, connecting in the bottom of each side plate and have base plate 4, described base plate 4 specifically to be hinge mode or can be fixedly connected mode with fixtures such as clasp nails with the connected mode of side plate.Be respectively connected with removable box cover 2 at the top of every side plate, removable box cover 2 and side plate connect as one and are provided with folding line in the junction of side plate Yu removable box cover 2.It is provided with the folding line for turnover between each side plate so that each side plate connects as one, constitutes the casing 1 with memory space together with base plate 4.
Vertically it is provided with reinforcing prop 3 on each corner in casing 1, base plate 4 is correspondingly provided with the slot 5 for fixing reinforcing prop 3.In the present embodiment, described reinforcing prop 3 be specially in the batten of L-shaped structure, extrusion coating paper pallet, PE plastic plate any one.As in figure 2 it is shown, the slot 5 being used in combination with reinforcing prop 3 is also for L-shaped structure.Certainly, described reinforcing prop 3 can also be angle steel or the L-shaped structure of other materials of L-shaped structure.
In order to conveniently grab by casing 1 in handling process, at least offer gripping groove 10 at one group of symmetrical side plate outer surface.
As it is shown on figure 3, described base plate 4 is mainly composited by core paper layer 6, buffering resistance to compression layer 7, corrugated layer 8 hot pressing mutually bonding with layers of kraft paper 9 from top to down.In the present embodiment, described buffering resistance to compression layer 7 is composited by 2～7 layers of honeycomb ply of paper is bonding.And described core paper layer 6 is composited by the corrugated paper of more than 3 layers is bonding, corrugated layer is that 5～8 layers of corrugated paper is bonding to be composited.
The surfaces externally and internally of described base plate 4 and side plate is coated with one layer of waterproof layer, and described waterproof layer is specially the marine glue of existing routine, water-repellent paint.
The multifunctional packaging carton of this structure is in use, after side plate, base plate 4 and removable box cover 2 are installed one casing 1 with memory space of composition, then L-shaped reinforcing prop 3 is inserted the slot 5 being arranged on base plate 4, finally loads and need article to be packaged, seal and pack；Certainly according to the packing instructions of article, also optional without loading reinforcing prop 3 (such as some article lightweight, non-friable) when packaging, the use of reinforcing prop 3 is the most flexible.
These are only explanation embodiment of the present utility model; it is not limited to this utility model, for a person skilled in the art, all within spirit of the present utility model and principle; the any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
