The functional sealing container 10 of the present invention seals the freshly ground ground beans in a good blending state as it is so that the initial flavor can be maintained even after long-term storage.

Coffee beans, which are harvested, are in a state where the original flavor of the beans is easily destroyed as we go through the coffee. If you leave it alone, the flavor can change little and last for years. However, the ground coffee powder tends to change flavor faster than roasted beans. A week after the roasted bean is in contact with the air, the ground coffee powder begins to lose its flavor after an hour and the boiled coffee in just a few minutes. Since ancient times, the Arabs have all begun to distribute, crush, and extract the problem within 30 minutes. One of the easiest and most effective methods that have been transmitted so far is to grind fresh roasted beans immediately before extracting and drinking them.

In order to store the ground ground coffee without deterioration for a long time, the ground coffee powder is tightly sealed by blocking contact with oxygen and moisture. The material of the container may be oxygen and fluid impermeable material, and the oxygen contained in the packaged contents may be removed or nitrogen gas may be mixed to prevent the penetration of other gases and moisture in advance.

It is generally known that 1 mm thick coffee powder is suitable for extracting espresso coffee. For ground coffee, you need about 5 to 8 g to brew a cup. The apparent specific gravity of the less compressed ground coffee is approximately 0.6-0.8 g / cc.
