<P>PROBLEM TO BE SOLVED: To provide an inside plug and a cap with an inside plug each facilitating separation and recovery from a vessel without damaging the intrinsic function of the inside plug such as mating force with an opening of the vessel and airtightness to the cap. <P>SOLUTION: The synthetic resin-made inside plug has: an outer tube 10 mating with the opening 101 of the vessel; a circular upper panel 20 extending from the upper end of the outer tube 10 to the inner side; and a pouring out tube 30 having a diameter smaller than that of the outer tube 10 connected to the inner end portion of the upper panel 20. A gripping part 50 is connected to the upper panel 20 via a connecting part 51, and separates the outer tube 10 from the opening 101 of the vessel by gripping the gripping part 50 and lifting the upper panel 20 via the connecting part 51. <P>COPYRIGHT: (C)2007,JPO&INPIT |
