Abstract

Coated pharmaceutical packages are disclosed. The coated pharmaceutical packages may include a glass body comprising a first surface and a second surface opposite the first surface. The glass body may be a glass container formed from a borosilicate glass composition and the first surface is an exterior surface of the glass container. A low-friction coating may be positioned on at least a portion of the first surface of the glass body. In embodiments, the low-friction coating may be a fluoropolymer.

First claim

What is claimed is:

1 . A coated pharmaceutical package comprising:
a glass body comprising a first surface and a second surface opposite the first surface, wherein the glass body is a glass container formed from a borosilicate glass composition and the first surface is an exterior surface of the glass container; and a low-friction coating positioned on at least a portion of the first surface of the glass body, the low-friction coating comprising a fluoropolymer.

2 . The coated pharmaceutical package of claim 1 , wherein the low-friction coating comprises:
a coupling agent layer positioned on the first surface of the glass body; and a polymer layer positioned over the coupling agent layer, the polymer layer comprising the fluoropolymer.

3 . The coated pharmaceutical package of claim 1 , wherein the coupling agent layer comprises a silsesquioxane.

4 . The coated pharmaceutical package of claim 1 , wherein the low-friction coating has a coefficient of friction of less than or equal to 0.6.

5 . The coated pharmaceutical package of claim 1 , wherein a thickness of the low friction coating is less than or equal to 1 μm.

6 . The coated pharmaceutical package of claim 1 , wherein a thickness of the low friction coating is less than or equal to 100 nm.

7 . The coated pharmaceutical package of claim 1 , wherein the coated pharmaceutical package is thermally stable at a temperature of at least about 260° C. for 30 minutes.

8 . The coated pharmaceutical package of claim 1 , wherein a retained strength of the pharmaceutical package in horizontal compression does not decrease by more than about 20% after exposure to an elevated temperature of 260° C. for 30 minutes and abrasion under a 30 N load.

9 . The coated pharmaceutical package of claim 1 , wherein the portion of the exterior surface of the coated pharmaceutical package with the low-friction coating contains less than 6 glass checks per 5 mm length when abraded along a length of about 20 mm with a second coated borosilicate glass pharmaceutical package in a vial-on-vial testing jig under a normal load of 30 N and after exposing the coated glass pharmaceutical package and the second coated glass pharmaceutical package to a temperature of at least about 260° C. for 30 minutes.

10 . A coated pharmaceutical package comprising:
a glass body comprising a first surface and a second surface opposite the first surface, wherein the glass body is a glass container formed from an alkali aluminosilicate glass having a Class HGA 1 hydrolytic resistance when tested according to the ISO 720-1985 testing standard and the first surface is an exterior surface of the glass container; and a low-friction coating positioned on at least a portion of the first surface of the glass body, the low-friction coating comprising a fluoropolymer.

11 . The coated pharmaceutical package of claim 10 , wherein the low-friction coating comprises:
a coupling agent layer positioned on the first surface of the glass body; and a polymer layer positioned over the coupling agent layer, the polymer layer comprising the fluoropolymer.

12 . The coated pharmaceutical package of claim 11 , wherein the coupling agent layer comprises a silsesquioxane.

13 . The coated pharmaceutical package of claim 10 , wherein the low-friction coating has a coefficient of friction of less than or equal to 0.6.

14 . The coated pharmaceutical package of claim 10 , wherein a thickness of the low friction coating is less than or equal to 1 μm.

15 . The coated pharmaceutical package of claim 10 , wherein a thickness of the low friction coating is less than or equal to 100 nm.

16 . The coated pharmaceutical package of claim 10 , wherein the coated pharmaceutical package is thermally stable at a temperature of at least about 260° C. for 30 minutes.

17 . The coated pharmaceutical package of claim 10 , wherein a retained strength of the pharmaceutical package in horizontal compression does not decrease by more than about 20% after exposure to an elevated temperature of 260° C. for 30 minutes and abrasion under a 30 N load.

18 . The coated pharmaceutical package of claim 10 , wherein the portion of the exterior surface of the coated pharmaceutical package with the low-friction coating contains less than 6 glass checks per 5 mm length when abraded along a length of about 20 mm with a second coated borosilicate glass pharmaceutical package in a vial-on-vial testing jig under a normal load of 30 N and after exposing the coated glass pharmaceutical package and the second coated glass pharmaceutical package to a temperature of at least about 260° C. for 30 minutes.

19 . A coated pharmaceutical package comprising:
a glass body comprising a first surface and a second surface opposite the first surface, wherein the glass body is a glass container formed from a borosilicate glass composition and the first surface is an exterior surface of the glass container; and a low-friction coating positioned on at least a portion of the first surface of the glass body, the low-friction coating comprising a silsesquioxane-based polymer.

20 . The coated pharmaceutical package of claim 19 , wherein the low-friction coating has a coefficient of friction of less than or equal to 0.6.

21 . The coated pharmaceutical package of claim 19 , wherein a thickness of the low friction coating is less than or equal to 1 μm.

22 . The coated pharmaceutical package of claim 19 , wherein a thickness of the low friction coating is less than or equal to 100 nm.

23 . The coated pharmaceutical package of claim 19 , wherein the coated pharmaceutical package is thermally stable at a temperature of at least about 260° C. for 30 minutes.

24 . The coated pharmaceutical package of claim 19 , wherein a retained strength of the pharmaceutical package in horizontal compression does not decrease by more than about 20% after exposure to an elevated temperature of 260° C. for 30 minutes and abrasion under a 30 N load.

25 . The coated pharmaceutical package of claim 19 , wherein the portion of the exterior surface of the coated pharmaceutical package with the low-friction coating contains less than 6 glass checks per 5 mm length when abraded along a length of about 20 mm with a second coated borosilicate glass pharmaceutical package in a vial-on-vial testing jig under a normal load of 30 N and after exposing the coated glass pharmaceutical package and the second coated glass pharmaceutical package to a temperature of at least about 260° C. for 30 minutes.
