Description

Packing boxes

technical field

The utility model relates to a packing box, in particular to a packing carton with a paper inner box body for shockproof protection.

Background technique

At present, for various fragile, light and handy, special-shaped glass, pottery and other products, such as cups, basins, light bulbs, etc., the packaging liner inner box for shockproof protection is usually made of foam, plastic or cardboard with good shockproof effect.

Although the product packaging liner inner box made of foam or plastic materials has better shockproof effect, the production of foam or plastic materials consumes a lot of energy, pollutes the environment seriously after use, and takes up a lot of space during transportation and storage, and is inconvenient to use.

Although the inner box of the product packaging liner made of cardboard material is better in environmental protection, it needs to be formed before use for transportation and storage, which takes up a lot of space and consumes more man-hours for packaging and use. In addition, it is necessary to punch holes and cut corners during processing to make them correspond to the product, so as to clamp the product to achieve shockproof effect. The punched and cut off corners during processing become Useless waste, resulting in a large amount of waste of cardboard materials, a serious waste of resources.

Contents of the invention

The utility model aims to solve the problems of material waste in the inner box of the packaging liner processed by the above-mentioned cardboard material, and provides a material-saving and easy-to-use packaging carton.

A packaging carton described in the utility model comprises an inner box body with a rectangular or triangular cross section and an outer box body correspondingly sleeved on the inner box body, each edge and corner of the inner box body is respectively provided with a Inner knuckles with opposite corners, the outer two longitudinal sides of the inner knuckles are respectively connected to the two sides of the inner knuckles, and the inner knuckles extend into the inner box body; and each corner of the inner box body is provided with at least two inner knuckles.

The inner ends of the inner knuckles on the corners of the inner box body can be respectively provided with outer knuckles.

In the utility model, the corners of the paper inner box body are respectively provided with inner corners opposite to the corners, so that the inner ends of the inner corners clamp the product to achieve the shockproof effect, and the upper and lower thicknesses of the inner corners extend into the inner box. The depth in the box can be set according to the specific product, and there is no material waste when processing the entire inner box. In application, the product is placed in the inner box body, and then the inner corners on the corners of the inner box are respectively pressed inward to form inner corners opposite to the corners. Therefore, the utility model has the advantages of material saving, convenient use and the like.

Detailed ways

As shown in Figure 1, a kind of packing carton, comprises the inner box body 1 that cross section is rectangular and the outer box body 2 that is sheathed on this inner box body correspondingly, each corner of described inner box body 1 is respectively provided with The inner knuckle 3 opposite to its corner, the outer two longitudinal sides of the inner knuckle 3 are respectively connected to the two sides of the corner, and the inner knuckle 3 extends into the inner box body 1; each corner of the inner box body 1 is provided with at least two inside chamfer 3. The cross section of the inner box body 1 can also be triangular.

In FIG. 2 , a light bulb product 41 is placed in the inner box body 1 , and the inner knuckles 3 on the corners of the inner box body 1 clamp the light bulb product 41 . In Fig. 3, in the inner box body 1 is another product 42, and the inner end of the upper inner corner of each corner of the inner box body is also provided with outer corners 5, and each corner is respectively provided with three inner corners.

When applying, press the movable parts of the inner corners on the corners of one end of the inner box body inward respectively to form the inner corners opposite to the corners, then put the products to be packaged correspondingly, and then put the corners of the other end of the inner box body The movable parts of the inner knuckles on the top are respectively pressed inward to form the inner knuckles opposite to the corners and clamp the product, and finally the corresponding outer box body 2 is set on the outside of the inner box body 1 .

According to the specific shape of the desired packaged product, the corners of the inner box body 1 as shown in Figure 3 can be respectively set to the outer corners 5 opposite to the corners to make it more compatible with the shape of the product. The upper and lower thicknesses of the inner knuckles on each corner of the inner box body 1 are related to the strength of the inner knuckles; the depth of the inner knuckles extending into the inner box body is related to the outer diameter of the packaged product, and they can be set correspondingly by specific products.

Claims (2)
