A nano-preservation and moisture-proof calcium-plastic box

Abstract

The application relates to a nano-preservation and moisture-proof calcium-plastic box, which includes an upper box body and a base. The four corners of the upper box body are provided with support columns extending downward, and the lower ends of the support columns are connected to the base. The support column A plurality of storage boxes are vertically slidably connected to each other. Abutting grooves are provided at the four corners of the storage boxes, and the support columns can be abutted in the abutment grooves. Between the side walls of the storage boxes and the support columns, There is a locking piece, the locking piece includes mounting blocks symmetrically arranged on two opposite side walls of the storage box, the mounting blocks are provided with extension columns perpendicular to the side walls of the storage box, and the locking piece also includes Rotate the hinge plate connected to the support column, the hinge plate corresponds to the extension column one by one, the hinge plate can be rotated so that the hinge plate abuts against the surface of the extension column, and the locking member also includes a The connectors that connect the columns together. The present application has the possible effect of reducing the fruit being crushed.

Description

technical field [0001] The present application relates to the field of packaging boxes, in particular to a nano fresh-keeping moisture-proof calcium-plastic box. Background technique [0002] At present, the nano-calcium plastic box is a kind of preservation box that is more and more widely used. It is made of high-density polyethylene and some nanoparticles are added to the raw material. It has the characteristics of moisture resistance and good mechanical properties. In addition, some nano-adsorbents are added to the raw materials to absorb the ethylene released when fruits and vegetables are stored, so that the box can also prolong the storage time of fruits and vegetables. [0003] The relevant calcium-plastic box mainly includes a box body, and also includes a box cover that is folded and connected to the box body. When in use, the goods are put into the box body and then the box cover is closed. [0004] In view of the above-mentioned related technologies, the invento...
