A method for manufacturing a decorative glass container (2, 10, 10') comprising, on the upper part of the glass container (2, 10, 10'), in the following order: a lower layer including a thick wall portion (10a', 10b, 12a) and a thin wall portion (10a, 10b', 12b); a vapor-deposition layer patterned by a forming region and a non-forming region; and an overcoat layer made of a UV curable resin, the method comprising: a step of forming entirely the lower layer on the upper part of the glass container; a step of forming entirely the vapor-deposition layer on the upper part of the lower layer; a step of removing simultaneously a part of the vapor-deposition layer and lower layer by a laser processing, forming a vapor-deposition layer patterned by a forming region and a non-forming region, and exposing a part of the lower layer to give a thin wall portion (10a, 10b', 12b) of the lower layer; and a step of forming the overcoat layer on the upper part of the patterned vapor-deposition layer and the thin wall portion (10a, 10b', 12b) of the lower layer by coating of a UV curable resin and carrying out UV radiation, and forming a contact region in which the lower layer and the overcoat layer are in direct contact with each other by way of the non-forming region of the vapor-deposition layer. a lower layer including a thick wall portion (10a', 10b, 12a) and a thin wall portion (10a, 10b', 12b); a vapor-deposition layer patterned by a forming region and a non-forming region; and an overcoat layer made of a UV curable resin, the method comprising: a step of forming entirely the lower layer on the upper part of the glass container; a step of forming entirely the vapor-deposition layer on the upper part of the lower layer; a step of removing simultaneously a part of the vapor-deposition layer and lower layer by a laser processing, forming a vapor-deposition layer patterned by a forming region and a non-forming region, and exposing a part of the lower layer to give a thin wall portion (10a, 10b', 12b) of the lower layer; and a step of forming the overcoat layer on the upper part of the patterned vapor-deposition layer and the thin wall portion (10a, 10b', 12b) of the lower layer by coating of a UV curable resin and carrying out UV radiation, and forming a contact region in which the lower layer and the overcoat layer are in direct contact with each other by way of the non-forming region of the vapor-deposition layer. a step of forming entirely the lower layer on the upper part of the glass container; a step of forming entirely the vapor-deposition layer on the upper part of the lower layer; a step of removing simultaneously a part of the vapor-deposition layer and lower layer by a laser processing, forming a vapor-deposition layer patterned by a forming region and a non-forming region, and exposing a part of the lower layer to give a thin wall portion (10a, 10b', 12b) of the lower layer; and a step of forming the overcoat layer on the upper part of the patterned vapor-deposition layer and the thin wall portion (10a, 10b', 12b) of the lower layer by coating of a UV curable resin and carrying out UV radiation, and forming a contact region in which the lower layer and the overcoat layer are in direct contact with each other by way of the non-forming region of the vapor-deposition layer.
