Abstract

A hollow glass body includes a cylindrical main body portion having a first inside diameter, and a first end opening and a second end opening on opposite ends of the hollow glass body. The hollow glass body has a second inside diameter at the second end opening. The second inside diameter is smaller than the first inside diameter. A difference between the first inside diameter and the second inside diameter is at most 100 μm.

First claim

The invention claimed is:

1 . A hollow glass body, comprising:
a cylindrical main body portion having a first inside diameter; and a first end opening and a second end opening on opposite ends of the hollow glass body, wherein: the second end opening delimits the cylindrical main body portion and the hollow glass body has a second inside diameter at the second end opening; the second inside diameter is smaller than the first inside diameter; and a difference between the first inside diameter and the second inside diameter divided by the first inside diameter is smaller than 0.01.

2 . The hollow glass body according to claim 1 ,
wherein the difference between the first inside diameter and the second inside diameter is at most 50 μm.

3 . The hollow glass body according to claim 1 ,
wherein the difference between the first inside diameter and the second inside diameter is at most 30 μm.

4 . The hollow glass body according to claim 1 ,
wherein the first inside diameter is smaller than 28 mm.

5 . The hollow glass body according to claim 4 ,
wherein the first inside diameter is smaller than 12 mm.

6 . The hollow glass body according to claim 1 ,
wherein the cylindrical main body portion has an outside diameter that is smaller than 30 mm.

7 . The hollow glass body according to claim 6 ,
wherein the outside diameter is smaller than 9 mm.

8 . The hollow glass body according to claim 1 ,
wherein a wall thickness of the cylindrical main body portion is between 0.7 mm and 1.1 mm.

9 . The hollow glass body according to claim 1 ,
wherein a third inside diameter at the first end opening is smaller than the second inside diameter.

10 . The hollow glass body according to claim 9 ,
wherein the third inside diameter is smaller than 5 mm.

11 . The hollow glass body according to claim 1 ,
wherein the second end opening comprises a laser cut area.

12 . The hollow glass body according to claim 1 ,
wherein the difference between the first inside diameter and the second inside diameter divided by the first inside diameter is smaller than 0.005.

13 . The hollow glass body according to claim 1 ,
wherein the difference between the first inside diameter and the second inside diameter divided by a wall thickness of the cylindrical main body portion is smaller than 0.05.

14 . The hollow glass body according to claim 1 ,
wherein the hollow glass body is a receptacle, or an intermediate product for manufacturing a receptacle.

15 . The hollow glass body according to claim 1 , further comprising a cone at a side of the cylindrical main body portion opposite the second end opening.

16 . The hollow glass body according to claim 15 ,
wherein the cone comprises the first end opening.

17 . The hollow glass body according to claim 15 ,
wherein the cone is a syringe cone.

18 . The hollow glass body according to claim 1 ,
wherein the hollow glass body is a syringe barrel.

19 . The hollow glass body according to claim 1 ,
wherein the hollow glass body is a medical cartridge.

20 . The hollow glass body according to claim 1 ,
wherein the difference between the first inside diameter and the second inside diameter divided by a wall thickness of the cylindrical main body portion is smaller than 0.2.

21 . A receptacle, comprising:
the hollow glass body according to claim 1 .

22 . The receptacle according to claim 21 ,
wherein the receptacle is a medical receptacle.

23 . The receptacle according to claim 21 , further comprising a formulation which comprises at least one pharmaceutically active substance or a pharmaceutical carrier substance.
