PROBLEM TO BE SOLVED: To provide a package causing neither fluctuation of a sol-gel transition temperature of a perfume-containing thermally responsive gel composition nor losing of gelation property in its use and, when added a medicinal component thereto, exerting increased medicinal effect expected based on the gel retention in oral cavity. SOLUTION: The package filled with a thermally responsive gel composition for oral cavity is obtained by filling the composition into a container having an inner surface comprising a polyethylene terephthalate resin, wherein the composition comprises a surfactant, ethanol and a perfume and has 20-45°C sol-gel transition temperature where the surfactant is based on a thermally responsive block copolymer of polyoxyethylene-polyoxypropylene.
