To provide a glass bottle with a seal and a heat-sensitive label affixed thereto in which the adhesive force of the seal and the heat-sensitive label to a glass surface is improved, and degradation of the adhesive force caused by weathering of glass is suppressed.
A top surface of a mouth part to which the seal of the glass bottle affixed thereto and a barrel part to which the heat-sensitive label are treated with water, alcohol, or any solution containing inorganic or organic acid. Alkali contents in the vicinity of the glass surface and internal surface are removed by this treatment, a so-called dealkalized state is realized, and the adhesive strength of a thermosoftening adhesive is improved. The exudation quantity of the alkali content to the surface when the glass is weathered is reduced, the quantity of inorganic salt deposited on the surface is reduced, and degradation of adhesivity of the thermosoftening adhesive is suppressed.
