Description

A packaging box with film suspended positioning protection

Technical Field

The utility model belongs to the technical field of packaging protection pieces, in particular to a packaging box with film suspended positioning protection.

Background Art

A packaging box is a commonly used storage and transportation container for goods, which is mainly used in various links of commodity circulation to protect commodities and facilitate storage and transportation. In the prior art, in order to prevent some fragile commodities from being damaged by external vibrations during logistics and transportation, workers often fill packaging boxes with buffering materials such as sawdust, cotton, and foam materials to provide buffering and shock-absorbing protection for the commodities. The protective effect of the above-mentioned traditional protection methods depends on the quality of the buffering material and the fragility of the commodities. The protective effect is not ideal, and a large amount of buffering material is required, which not only increases the packaging cost, but also aggravates environmental pollution. There will also be problems such as the escape of buffering materials during use. Therefore, new solutions are urgently needed on the market to solve the above problems.

Utility Model Content

The utility model aims to provide a packaging box with suspended film positioning protection, which has good protection and buffering effect and avoids the escape of buffering materials, and is simple and environmentally friendly.

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

The utility model discloses a packaging box with film suspended positioning protection, which is used for containing and protecting articles collected on behalf of others, and comprises a rectangular outer box, wherein four flap plates are arranged on the opening of the rectangular outer box, the flap plates are connected to the four sides of the opening as a whole, and folds are formed at the connection points; the utility model also comprises a fixing plate and an elastic film, wherein the fixing plates are provided with two pieces, the elastic film covers the opening and the two ends extend to the flap plates arranged on the left and right sides of the opening and cover the middle of the flap plates, the part of the elastic film covered on the flap plates is uniformly provided with a plurality of glue penetration holes, and the fixing plate and the flap plates are fixed as a whole by adhesives with the ends of the elastic film being clamped therebetween.

Beneficial effect: The use process of this technical solution is as follows: place the items to be received on the elastic film at the opening, fold the flaps on the left and right sides of the opening inward to the surface of the opening, and finally fold the front and rear flaps inward to the surface of the opening to complete the packaging. At this time, the elastic film firmly bonded to the fixed plate and the flap is forced to stretch to the left and right during the folding process of the left and right flaps. The items to be received are pushed downward by the pressure of the flap, further squeezing and stretching the elastic film. At this time, the elastic film has a large enough elastic potential energy, so that the items to be received are tightly pressed between the elastic film and the folding plate. This solution uses the excellent ductility and resilience of the elastic film to form a firm covering buffer structure with the elastic film, the items to be received, the flap, the fixed plate and the rectangular outer box, which effectively improves the buffer protection effect, has a simple structure, eliminates the use of filling buffer materials, avoids the problem of buffer material escape, and reduces environmental pollution and production costs.

As a further improvement of the above technical solution: it also includes a folding plate, the fixed plate and the folding plate are connected as a whole and form a connecting fold, the connecting fold coincides with the left and right sides of the opening respectively, and a plurality of rectangular openings are evenly distributed at the connecting fold along the upper edge of the folding plate. This improvement adds a folding plate between the fixed plate and the elastic film, further enhancing the protection and cushioning performance of the transported items, and at the same time, the setting of the rectangular opening reduces the resistance of the folding plate during the turning process, making it easier to use.

As a further improvement of the above technical solution: the elongation of the elastic film is δ, and 150%≤δ≤400%. This improvement enables the elastic film to have better ductility and tensile strength, and has good load-bearing and protective performance for large and heavy items to be collected.

As a specific solution of the above technical solution, the material of the elastic film is at least any one of OPS, PE, PVC, POF, and PET.

As a further improvement of the above technical solution, the two folding plates form a mutually interlocking trapezoidal structure at the edges in contact with each other, which further enhances the relative stability of the two folding plates in the closed state, and the folding plates are not easily disturbed and deviated by external forces in the mutually interlocking state.
