A dental floss container is provided that may include a container that defines a fluid chamber. This provides more efficient and safer use of a machine tool by automating the aiming of fluids at a desired location. Each of the plurality of photonic crystal units may have a structure such that a first material having a relatively high refractive index and a second material having a relatively low refractive index are periodically arranged so as to transmit light having a wavelength band corresponding to a photonic band gap. The compliant nature of the outer layer causes it to distort against the force distribution material when acted on by a concentrated external load. Accordingly, the surge suppression optimization device connected in a path from which surges pass can significantly reduce energy of a surge flowing in and a residual surge voltage.
