Description

TECHNICAL FIELD

[0001] The utility model relates to a foamed box field, especially in a kind of multi-layer composite high-efficiency buffer foamed box. BACKGROUND

[0002] Foamed box is the box type packaging container made of foamed plastic, and its interior has many small pores.This box has the characteristics of small density, good impact load absorption, good heat insulation and sound insulation effect, high specific strength, etc., and is widely used in many fields.In the food industry, foamed box is often used for low-temperature refrigeration and transportation of organic vegetables, seasonal fruits, seafood, dairy products, beverages, etc., and can be used with ice bag to refrigerate and transport various biological frozen reagents and foreign trade fresh-keeping food.In addition, foamed box is also used for transportation of lamps, automobile parts and packaging of goods.

[0003] The buffering effect of traditional foamed box needs to be improved.When the side wall of the foamed box is inadvertently collided or extruded at the part far from the corner, these parts are often relatively fragile and prone to damage.The specific performance is that the side wall may have cracks or even completely break, accompanied by the falling of foamed material fragments.This damage not only affects the overall structural integrity of the foamed box and reduces its ability to protect the internal goods from external impact, but also may cause secondary damage to the goods in the package or contaminate the surface of the goods.In addition, the frequent damage phenomenon also shortens the service life of the foamed box, increases the replacement cost, and the falling foamed fragments may also have adverse effects on the environment if not properly handled.Therefore, the present application proposes a multi-layer composite high-efficiency buffer foamed box to solve the above problems. SUMMARY

[0004] The main purpose of the utility model is to provide a multi-layer composite high-efficiency buffer foamed box, which can effectively solve the problems in the background art.

[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:

[0006] A multi-layer composite high-efficiency buffer foamed box, comprising a buffer foamed box body, the buffer foamed box body is composed of a foamed bottom plate, an outer foamed shell, an inner foamed shell, a square tubular rubber air bag, a movable foamed plate and a plastic film, the outer foamed shell and the inner foamed shell are both installed at the upper end of the foamed bottom plate, and the inner foamed shell is located inside the outer foamed shell, the square tubular rubber air bag is installed between the outer foamed shell and the inner foamed shell, the movable foamed plate has several and is all movably installed in the outer foamed shell, and the plastic film is sleeved on the outer side of the foamed bottom plate, the outer foamed shell and the several movable foamed plates.

[0007] Preferably, a foamed box upper cover is installed at the upper end of the buffer foamed box body.

[0008] Preferably, the foam bottom plate and the outer foam shell on the buffer foam box body are both square tubes, and the foam bottom plate and the outer foam shell are fixedly connected with the foam bottom plate.

[0009] Preferably, a plurality of foam plate installation through grooves are formed in the wall of the foam bottom plate on the buffer foam box body, and the plurality of foam plate installation through grooves penetrate the wall of the foam bottom plate.

[0010] Preferably, the plurality of movable foam plates on the buffer foam box body are movably installed in the plurality of foam plate installation through grooves formed in the wall of the foam bottom plate, and the plurality of movable foam plates are in contact with the outer wall of the square tube-shaped rubber air bag.

[0011] Preferably, the plastic film of the buffer foam box body is fixedly connected with the foam bottom plate, the outer foam shell and the plurality of movable foam plates.

[0012] Compared with the prior art, the buffer foam box body has the following beneficial effects:

[0013] By setting the buffer foam box body composed of the foam bottom plate, the outer foam shell, the inner foam shell, the square tube-shaped rubber air bag, the movable foam plate and the plastic film, the buffer effect of the buffer foam box body is better. When the side wall of the buffer foam box body is away from the corner and is subjected to impact or extrusion, that is, the movable foam plate is subjected to extrusion, the movable foam plate will move inward to extrude the square tube-shaped rubber air bag. At this time, the plastic film will deform, and the square tube-shaped rubber air bag will elastically deform. Therefore, in the process of elastic deformation of the square tube-shaped rubber air bag, the impact force can be buffered. At the same time, the existence of the plastic film can reduce the probability of breakage of the foam bottom plate, the outer foam shell and the movable foam plate. The existence of the square tube-shaped rubber air bag can reduce the probability of breakage of the inner foam shell. Even if the foam bottom plate, the outer foam shell and the movable foam plate are broken, the foam fragments will not fall off due to the blocking of the plastic film, thereby ensuring the integrity of the buffer foam box body and the ability of the buffer foam box body to protect the internal articles from external impact. In addition, the foam fragments can also avoid polluting the internal articles and the external environment. BRIEF DESCRIPTION OF DRAWINGS
