Abstract

A glass container has an outer glass surface with an inkjet printed image provided on the surface. A cold-end coating (CEC) with a thickness between 0 to 20 nm is present between the outer glass surface and the inkjet printed image. Such glass container is preferably a one-way beverage bottle. A method of inkjet printing an image on a glass container comprises the steps of (a) manufacturing a glass container having a CEC layer; (b) removing at least part of the CEC layer to a level wherein the remaining CEC layer has a thickness of 0 to 20 nm; and (c) inkjet printing an image on the glass container.

First claim

The invention claimed is:

1. A method of inkjet printing an image on a glass container comprising the steps of:
(a) providing a glass container having a cold-end coating (CEC) layer, wherein the CEC layer is at least partially water soluble;
(b) removing part of the CEC layer to a level wherein the remaining CEC layer has a thickness of up to 20 nm by rinsing the CEC from the glass container with water;
(c) blowing the water from the container by means of a pressurised air stream; and
(d) inkjet printing an image on the glass container;
said glass container having an internal burst pressure of at least 7 bar after being exposed to the printing.

2. The method according to claim 1 , comprising the step of applying a primer layer on the glass container after at least partial removal of the CEC and prior to inkjet printing an image on the glass container.

3. The method according to claim 1 , comprising the step of applying a protective layer and/or clear coating on top of the inkjet printed image.

4. The method according to claim 1 , wherein the CEC from the glass container is rinsed with water at a temperature between 20° C. and 90° C.

5. The method according to claim 1 , wherein removal of the CEC increases the slip angle of the glass container with at least 6°.

6. The method according to claim 1 , comprising the steps of filling the container with a liquid, preferably a beverage after inkjet printing the image thereon.

7. The method according to claim 1 , wherein the remaining CEC layer has a thickness of up to 10 nm.

8. A glass container having an outer glass surface with an inkjet printed image provided on said surface, wherein a cold-end coating (CEC) with a thickness up to 20 nm is present between the outer glass surface and the inkjet printed image; wherein said glass container is obtained by a method according to claim 1 .
