Space-saving is the main objective of this redesign project with a few conditions – the original material and the carrying rack are retained because of its stability, reusability and sustainability.
I came across a round two-story stainless steel tiffin box, which is used as a food delivery container by a big asian restaurant company. It is very robust and practical, but it has some flaws.
Brief & idea.
Sustainable consumption has become a hype for the urban lifestyle since the alarm about the plastic overuse and micro-plastic contamination in the ocean was raised.
Many companies and business owners raised awareness and took actions to support consumers’ demand. Lately, there are many new sustainable products and packaging designs in the market, especially for convenience food products, where is said to be the category that creates the most single-use packaging waste in the business.
The bowls are tapered towards the bottom to make it steadily stackable upside down without falling over when they are not in use.
Therefore, there is a second lid to support the bottom of the top layer with a cavity that fits the bottom of the bowl perfectly, which has a thin silicone ring along the edge underneath to keep the box tightly closed.
The groove on each side of the bowl is for preventing the vacuum suction in between while stacking.
The redesigned square tiffin box can be stacked steadily upside down and can save up to three times of the storage space. As well as the dispense of the extra spill-proof plastic lid which is placed underneath the metal lid.
The name “Qi” is derived from the Chinese word “蛣”, which means beetles. The beetles represent efficiency and mobility, while also being resistant and strong.
