PROBLEM TO BE SOLVED: To provide a glass vessel sealing device capable of reliably sealing an opening of a glass vessel without using any aluminum or aluminum alloy re-tightening cap, and easily unsealable. SOLUTION: Thermoplastic resin is formed on an opening end face of the glass vessel for storing liquid content. A sheet-like inner lid 4 and a thermoplastic resin out lid 5 are integrated with each other by the in-mold forming, and the integrated lid is fitted to the glass vessel. The inner lid 4 comprises a body formed of an aluminum foil or an aluminum alloy foil, a heat seal layer on a lower side of the body, and an adhesive layer on an upper side of the body. The inner lid 4 is adhered to the glass vessel by, for example, the induction heating system. The outer lid 5 comprises a shallow cap-like body 5a and an annular skirt 5b. The body 5a and the skirt 5b are connected by a discontinuous connection part 11 comprising a complete connection part and a plurality of partial connection pieces 11a. A projecting part 12 projecting to an upper position from a lower end of the body 5a is provided on an upper end corresponding to the discontinuous connection part 11 of the skirt 5b. |
