Decorative glass container and method for manufacturing decorative glass container

Abstract

Provided are a decorative glass container having clear boundary lines and good adhesion properties, and a method for manufacturing such a decorative glass container. The decorative glass container having, a lower layer including a thick wall portion and a thin wall portion, a vapor-deposition layer patterned by a forming region and a non-forming region, and an overcoat layer made of a UV curable resin, on the upper part of the glass container in order, and the method for manufacturing the decorative glass container, in which the forming region of the vapor-deposition layer is disposed on the upper part of the thick wall portion of the lower layer, the non-forming region of the vapor-deposition layer is disposed on the upper part of the thin wall portion of the lower layer by means of laser processing or the like, and a contact region is provided 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.

1 . A decorative glass container comprising:
 a lower layer including a thick wall portion and a thin wall portion;   a vapor-deposition layer patterned by a forming region and a non-forming region; and   an overcoat layer made of a UV curable resin, on the upper part of the glass container in order,   wherein the forming region of the vapor-deposition layer is disposed on the upper part of the thick wall portion of the lower layer, the non-forming region of the vapor-deposition layer is disposed on the upper part of the thin wall portion of the lower layer by a laser processing, and a contact region is formed 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.   
     
     
         2 . The decorative glass container according to  claim 1 , further comprising a patterned decorative layer which is formed between the patterned vapor-deposition layer and overcoat layer and is overlapped with the patterned vapor-deposition layer. 
     
     
         3 . The decorative glass container according to  claim 1 , wherein the overcoat layer is prepared by including a first overcoat layer and a second overcoat layer from underneath, and the hardness of the second overcoat layer is greater than that of the first overcoat layer. 
     
     
         4 . The decorative glass container according to  claim 1 , wherein the lower layer is prepared by including a first lower layer and a second lower layer from underneath, the first lower layer contains a thermosetting resin, and the second lower layer contains a UV curable resin. 
     
     
         5 . The decorative glass container according to  claim 1 , wherein a step difference part formed of a thick wall portion and a thin wall portion is formed on the surface of the glass container and each of the thick wall portion and thin wall portion of the lower layer is formed in response to the thick wall portion and thin wall portion on the surface of the corresponding glass container. 
     
     
         6 . A method for manufacturing a decorative glass container comprising, a lower layer including a thick wall portion and a thin wall portion, a vapor-deposition layer patterned by a forming region and a non-forming region, and an overcoat layer made of a UV curable resin, on the upper part of the glass container in order, the method comprising:
 (1) a step of forming entirely the lower layer on the upper part of the glass container;   (2) a step of forming entirely the vapor-deposition layer on the upper part of the lower layer;   (3) 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 of the lower layer; and   (4) a step of forming the overcoat layer on the upper part of the patterned vapor-deposition layer and the thin wall portion of the lower layer by coating of a UV curable resin and 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.   
     
     
         7 . The method for manufacturing a decorative glass container according to  claim 6 , further comprising a step (2′) for forming a decorative layer between the step (2) and step (3), wherein during the step (3), each of a part of the vapor-deposition layer, lower layer, and decorative layer is simultaneously removed and a part of the lower layer is exposed to form the thin wall portion of the lower layer.
