The present invention relates to a cup, and more particularly, it is easy to disperse loads and is robust, and can be sealed by putting a solid powder such as tea or grain powder inside the cup, and simply pour water to enjoy tea or food. It is about.

As is well known, modern people often use glass cups or mugs to drink water, coffee, and various beverages, but frequently use disposable cups that can be used more easily.

The most common form of such disposable cups is a round cup that can be placed on a table or on the floor. The round cup is made of paper and is kept for a long time while filled with water, coffee or other beverages. The liquid component of the contents penetrates into the paper cup and becomes dim, and thus, the contents may be spilled or spilled, and thus, there is a disadvantage in that it is difficult to use safely.
