Method Of Applying Hydro-Graphic Film To Articles
The present invention relates to articles such as plastic closures molded from polymeric materials the like having a hydro-graphic film applied thereto for enhancing aesthetic appeal. The present invention further relates to techniques for applying a coating to articles, such as plastic closures, with a hydro-graphic film ink, which method contemplates application of the ink to the articles in a water bath without first drying the ink, thereby maintaining the ink in fluid state, desirably avoiding the time-consuming and sometimes problematic steps of drying and reactivating the hydro-graphic film ink.
1 . A method of coating articles, comprising the steps of:
providing one or more articles to be coated, wherein each said article has at least one surface to be decorated;
printing a film with ink;
transferring the printed film to the surface of a fluid container, wherein said film is transferred without drying of the ink from which the film is printed; and
immersing said plurality of articles in said fluid container, and removing said article from said fluid container so that said ink is applied to said surface of each of said articles.
2 . A method of coating articles in accordance with claim 1 , wherein
said printing step and said transferring step are controlled and coordinated.
3 . A method of coating articles in accordance with claim 1 , wherein
said ink is maintained in a fluid state, so that said ink is applied to said articles without additional activation of said ink.
4 . A method of coating articles in accordance with claim 1 , wherein
said one or more articles include closures molded from a polymeric material each having a surface to which said ink is applied.
5 . A method of coating article in accordance with claim 1 , wherein
each of said one or articles are dried and/or cured after immersion.
6 . A method of coating article in accordance with claim 1 , wherein
each of said articles comprises a closure molded from a polymeric material having a circular top wall portion, and an annular skirt portion depending from said top wall portion, wherein said surface to which said ink is applied is an exterior surface of said top wall portion and said skirt portion.
7 . A method of coating articles, comprising the steps of:
providing one or more of articles to be coated, wherein each said article has at least one surface to be decorated;
transferring a film to the surface of a fluid in a fluid container;
printing an ink onto the film;
immersing said one or more article in said fluid container without drying of the ink printed onto the film, and removing said one or more articles from said fluid container so that said ink is applied to a surface of each of said one or more article.
8 . A method of coating articles in accordance with claim 7 , wherein
each of said articles comprises a closure molded from a polymeric material having a circular top wall portion, and an annular skirt portion depending from said top wall portion, wherein said surface to which said ink is applied is an exterior surface of said top wall portion and said skirt portion.
