Abstract

The present invention generally relates to apparatus and methods of coating glass containers and the containers produced therefrom. In particular, embodiments of the invention provide a method of coating glass containers by at least partially drying and/or curing one or more organic coatings on a glass container using accelerated drying.

Claims

1-41. -41. (canceled)

42. An apparatus for coating glass containers comprising:

a first optional pre-heating zone for pre-heating the glass container;

an organic coating applicator for applying a protective organic coating to the glass container;

a second optional pre-heating zone for pre-heating the glass container;

an accelerated drying zone for at least partially drying the protective organic coating on the glass container using accelerated drying;

cooling zone for cooling the protective organic coating on the glass container; and

a curing zone for curing the at least partially dried protective organic coating on the glass container.

43. The apparatus of claim 42, further comprising a decorator for applying a decorative label to the glass container prior to applying the protective organic coating to the glass container.

44. The apparatus of claim 42, further comprising an oxidizing zone for at least partially oxidizing the protective organic coating on the glass container.

45. The apparatus of claim 42, further comprising a conveyor belt and a plurality of chucks for transporting the glass container through the first optional pre-heating zone, the organic coating applicator, the second optional pre-heating zone, the accelerated drying zone, the cooling zone, and the curing zone.

46. The apparatus of claim 45, wherein the conveyor belt and the plurality of chucks comprise microwave-compatible materials.

47. The apparatus of claim 46, wherein the microwave-compatible materials comprise a material selected from the group consisting of Teflon, glass-filled Teflon, and PEEK.

48. The apparatus of claim 42, wherein the accelerated drying zone at least partially dries the protective organic coating on the glass container so that the integrity of the protective organic coating on the glass container is maintained during subsequent handling of the glass container.

49. The apparatus of claim 42, wherein the accelerated drying zone comprises a microwave oven.

50. The apparatus of claim 42, wherein the accelerated drying zone comprises an infrared irradiator.

51. The apparatus of claim 42, wherein the organic coating applicator comprises a sprayer, a dip tank, a roller, a silk-screener, or a combination thereof.

52. The apparatus of claim 42, wherein the optional first and/or second pre-heating zone comprises an energy source selected from the group consisting of thermal, IR radiation, microwaves, RF, and combinations thereof.

53. The apparatus of claim 42, wherein the curing zone comprises a lehr, an oven, or a combination thereof.

54. The apparatus of claim 42, wherein the apparatus comprises a mobile unit.
