Abstract

Disclosed is a method for manufacturing packaging including a container. The method includes: an operation of forming the container via blow molding or stretch blow molding from a plastics preform, an operation of treating an inner surface of the container, during which a thin barrier layer is formed on the inner surface via plasma-enhanced chemical vapor deposition; an operation of printing on an outer surface of the container, during which ink is deposited on the outer surface to form a decorative and/or informative inscription thereon.

First claim

The invention claimed is:

1. Method for manufacturing a packaging ( 2 ) comprising a container ( 3 ), with the method comprising:
forming the container ( 3 ) by blow molding or stretch blow molding from a preform ( 4 ) made of plastic;
printing an outer surface ( 13 ) of the container ( 3 ), during which an ink is deposited directly onto the outer surface ( 13 ) to form thereon a decorative and/or informative inscription ( 43 ), wherein the printing is carried out by ink jet or laser; and
treating, between the forming and printing, an inner surface ( 12 ) of the container ( 3 ) with a layer of plasma-assisted chemical vapor deposition, the layer having sufficient thickness to form a barrier between the inner surface ( 12 ) and contents of the container ( 3 ).

2. Manufacturing method according to claim 1 , wherein the barrier layer comprises amorphous hydrogenated carbon.

3. Manufacturing method according to claim 1 , wherein the printing is carried out by spraying.

4. Manufacturing method according to claim 1 , wherein during the printing operation, the container ( 3 ) is driven in rotation.

5. Manufacturing method according to claim 1 , further comprising, prior to the operation for forming the container ( 3 ), an operation for thermal conditioning of the preform ( 4 ).

6. Manufacturing method according to claim 2 , wherein the printing is carried out by spraying.

7. Manufacturing method according to claim 2 , wherein during the printing operation, the container ( 3 ) is driven in rotation.

8. Manufacturing method according to claim 3 , wherein during the printing operation, the container ( 3 ) is driven in rotation.

9. Manufacturing method according to claim 1 , wherein during the printing operation, the container ( 3 ) is driven in rotation.

10. Manufacturing method according to claim 6 , wherein during the printing operation, the container ( 3 ) is driven in rotation.

11. Manufacturing method according to claim 2 , further comprising, prior to the operation for forming the container ( 3 ), an operation for thermal conditioning of the preform ( 4 ).

12. Manufacturing method according to claim 3 , further comprising, prior to the operation for forming the container ( 3 ), an operation for thermal conditioning of the preform ( 4 ).

13. Manufacturing method according to claim 1 , further comprising, prior to the operation for forming the container ( 3 ), an operation for thermal conditioning of the preform ( 4 ).

14. Manufacturing method according to claim 4 , further comprising, prior to the operation for forming the container ( 3 ), an operation for thermal conditioning of the preform ( 4 ).

15. Manufacturing method according to claim 6 , further comprising, prior to the operation for forming the container ( 3 ), an operation for thermal conditioning of the preform ( 4 ).
