摘要

PROBLEM TO BE SOLVED: To meet a need for measures for preventing a leakage of gas from a connection part between an inner light bulb and an outer power source to solve a problem of conventional method for manufacturing a balloon with an inside lit-up and a sound generated therefrom.;SOLUTION: One or more balloon is provided in a balloon-like bag having an opening where a light source and a sound source are inserted from the opening into a gap with the balloon. When the inner balloon is expanded, the outer balloon-like bag is expanded so that the light source and the sound source are pressed against the faces between the balloon to be fixed thereto. Inside of the opening corresponds to an outside of the balloon, thereby preventing a gas leakage.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
