According to the simple opening / closing lid structure of the present invention, in the case of a simple paper container having no bent portion in the opening / closing portion, the opening / closing portion has a weak adhesive silicone resin layer which can be easily sealed and opened. And can be easily processed, so that an inexpensive container can be provided. Further, in the case of a container that requires a bent portion in the opening / closing portion, 1) the container can be easily and instantaneously opened and closed, 2) no bending accuracy is required, and 3) a strong stress is not required in the bent portion and the load is small. This eliminates the need for durability against repeated stress and enables long-term use. Furthermore, since dust does not easily adhere to the weakly adhesive silicone-based resin layer forming the opening / closing portion, the adhesive strength does not decrease, so that the paper container can be stably opened and closed for a long period of time.
