The combination of two moulded tubes produces a series of food containers to meet the needs of circular economy.

摘要

The combination of two forming tubes (24) is obtained by forming, so it has high productivity, easy to clean and reuse, and even can be stacked,-Each is closed or sealable at one end-Less than diameter in length, made of formable materials (recycled glass, metals, ceramics, bricks, plant composites), but excluding non Compostable Plastics,It aims to integrate the recycling economy of waste treatment into a series of food containers (1) with different capacities,Forming a fixed base for producing a series of food containers (1), wherein a third tube (17) is located in a central position, is opened at both ends, is made of rigid or semi-rigid material, has a length greater than its diameter, and adjusts its length as required.The central tube (17) can be an ethical biological source material, so that the food container (1) not only has the advantages of circular economy, but also can save inert raw materials.Abstract figure: figure 2A
