AI Technical Summary

Technical Problem

The lightweight cushioning material inside existing packaging cartons cannot effectively work with the carton body to resist greater pressure, making the cartons and their contents easily damaged.

Method used

A lightweight frame is installed inside the carton body and lid, forming a stable framework through components such as the base plastic frame, center support strip, side support strip, and short connecting ribs. It is connected by components such as core columns, side support columns, and diagonal rib columns to enhance the overall connection strength. Combined with foam cover and foam base plate, it provides top and bottom cushioning to form synergistic protection.

Benefits of technology

It effectively resists external pressure, reduces the risk of cardboard box deformation, enhances anti-deformation protection, prevents excessive deformation of cardboard boxes, and protects the safety of goods by absorbing and dispersing pressure through cushioning materials.

Abstract

This utility model discloses a lightweight cushioning packaging carton, including a carton body and a lid. The lid is fitted onto the top of the carton body. The carton body also includes a lightweight frame, a central plastic frame, a core column, side columns, diagonal ribs, and an expanded plastic frame. The lightweight frame includes a base plastic frame, a central support strip, side support strips, and short connecting ribs. A central support strip is fixed in the center of the inner frame wall of the base plastic frame. The lightweight frame is installed inside the carton body and the lid. The expanded plastic frame inside the lid is tightly bonded to the base plastic frame of the lightweight frame to enhance the overall connection strength. The base plastic frame inside the carton body is connected to the central plastic frame at three points on one side through the core column and side columns, and is reinforced by diagonal ribs, so that the carton body can effectively resist external pressure. Furthermore, the foam cover plate inside the lid and the foam base plate inside the carton body provide direct cushioning contact for the items from the top and bottom, respectively.
