Description

A foldable lens packaging box Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically to a foldable lens packaging box. Background Technology

[0002] Lenses are highly susceptible to wear and tear, especially with the increasing use of resin lenses. Even slight friction can affect their usability. Therefore, extra care should be taken when packaging lenses before they are mounted on frames. Currently, the most common packaging method for lenses is the use of paper bags, typically flat paper bags lined with flexible materials like non-woven fabric. However, even with these bags, it's difficult to prevent lenses from being damaged by pressure during transportation and sales. Another type of packaging is the box, which contains a support made of a relatively rigid yet flexible material. Within this support, a cavity matching the shape and size of the lens is formed, holding the lens in place. The support with the lens in place is then placed inside the box. This type of lens packaging is more complex and uses more expensive materials, making it unsuitable for most users. Utility Model Content
