Abstract
An airtight loose powder container includes an outer lid, an inner lid, an inner sifter and a base. The inner sifter is airtightly provided at an open end of the base, and the inner sifter is located between the inner lid and the base. The inner lid and the inner sifter are hinged through a hinge unit. The hinge unit is elastic, such that the inner lid under stress can move toward the inner sifter. When the outer lid covers the base, the outer lid squeezes the inner lid, such that the inner lid is airtightly attached to the inner sifter. The inner lid and the inner sifter hinged with each other are provided in the container. Under the squeezing force of the outer lid, the inner lid and the inner sifter can be tightly attached to each other.
