The innovation
The lid begins in the same sheet.
One paperboard blank forms the body, base, lid and hinge. The integral hinge links the edge of the lid to the body at the rim, keeping the lid attached when it is opened.

A different forming sequence
The design is intended for a dedicated forming machine. Starting with a single blank removes the need to source or match an independent lid for this design. A factory trial would establish the sequence, station requirements, line speed and operating limits.
What the design establishes
The lid and hinge originate from the same piece of paperboard as the container body and base. Category 1 S.A.S. holds the granted French patent.
What an industrial trial would establish
Material use and scrap, forming repeatability, closure performance, line speed, energy and the cost of saleable output.
From drinks to takeaway food
The same design principle can be explored across different container formats. Each format needs its own evaluation for the intended contents and conditions of use.
