The lower container itself of the container structure of the present invention is substantially bent by a method of multi-stage overlapping by taper fitting, or by a method that can be reduced and reduced without requiring a complicated operation as in the related art. Since the volume of the container can be reduced to a fraction, the sense of resistance to collecting the container and the consciousness of the high cost of collection can be greatly changed. In particular, the lower container, and the inner bag structure configured in combination with the lid, the container, which was conventionally discarded in one way due to the difficulty of cleaning the inner solution, is also used for the liquid contact part By exchanging the inner bag (or the lid integrally) or by using the inner bag together, the outer container can be easily collected and used repeatedly. Therefore, it is expected that the resources used for the container will be greatly saved, and that the amount of industrial waste will be reduced to contribute to environmental problems. In addition, it is possible to achieve a favorable effect on the product price due to the reduction of the container cost conventionally added to the product, or to reduce the distribution cost. In addition, by using a flexible sealing film suitable for use conditions such as a rubber or urethane sheet in a container having the structure of the present invention, the container can be used for a further multipurpose use. It can easily cope with the case where management of is required. Furthermore, it aims to break the practice of almost 100% industrial waste, such as the current 18-liter tin can, and at the same time, it is a great opportunity to shift the standard capacity to 20-liter cans and promote rationalization by increasing the size. I can do things.
