TIME LOCK by MINSEONG KIM from korea

Concept :
We can’t talk about the Korean food culture without mentioning side dishes. In Korea, almost all families tend to make side dishes as much as eating two or three times, put them in airtight containers and take as much as they can eat for one meal. They occasionally keep food ingredients in those containers and put them in refrigerators.
Because of this, people often don’t know for how long they have kept them. In consequence, they tend to dump old side dishes only after smelling or eating them.
To solve such a problem, some people write the date of keeping at the containers.
For time lock airtight containers, however, people don’t have to write such dates. They can check the date when they started to keep food by turning a time circle. They can eat side dishes and use ingredients which they started to keep first by checking dates when they began to keep them. As a result, there happen no such situations which they should throw away food because they don’t know when they began to keep them.

Green circle: People can check the date when they started to keep food through markings or numbers by turning the green circle. As people can separately rotate the green circle showing a monthly unit through markings and numbers and the inner white circle showing a day unit, they can know the accurate dates

Temperature circle: As the color of a green circle changes according to the temperature, people can know keeping conditions of side dishes. The lower the temperature gets, the clearer appears the green color. As the temperature goes up, an orange color appears, making people judging the temperature of side dishes.

Storage: There are containers of various sizes, but sizes of containers are suitable for clean adjustment. In consequence, people can easily keep them.
