Novel package box

Abstract

The invention discloses a novel package box. The novel package box comprises a box body and a box cover, wherein the box body comprises an inner box body and an outer box body; a gap is formed between the side wall of the inner box body and the side wall of the outer box body; the side wall of at least one side of the inner box body is an arcuately-deformed and outwardly-expanded elastic plate; the package box also comprises a pressing device used for generating pre-tightening extrusion force when the elastic plate recovers; the package box further comprises an air spring; the spring is arranged between the bottom wall of the inner box body and the bottom wall of the outer box body and is used for reducing vibration. According to the novel package box, a filling space formed after deformation of the elastic plate is filled with articles, the box cover is closed, the elastic plate recovers, the certain pushing force towards the interior of the box body is also applied to the elastic plate by the pressing device at the same time, the relative gaps among the filled articles is extruded under the combined action of the elastic plate and the pressing device, the articles are closely clung to one another, the relative movement among the articles is avoided, and the danger of collision caused by the relative movement is avoided; in addition, the air spring is arranged, so that the longitudinal vibration of the inner box body can be reduced.

Description

technical field [0001] The invention relates to the field of packaging, in particular to a novel packaging box. Background technique [0002] Packaging boxes are generally used for the circulation of goods to facilitate the turnover of goods, and play a vital role in our lives. The packaging box has a certain storage space, and is often used to pack a variety of fragile or inconvenient foods or objects that are not easy to collide. When the items in the packaging box are filled, they can only rely on the squeeze between the items in the box to form stability. When the gap is relatively loose, shaking will occur, and in severe cases, it will cause damage to the item. The existing common method is to add anti-vibration filler. Although the process is not complicated, it is time-consuming and labor-intensive, which is not conducive to cost saving. [0003] Therefore, it is necessary to improve the existing packaging boxes so that there is a relatively stable squeezing force be...
