Problems solved by technology

In this case, however, semi-finished tube processing is characterized by increased costs
In addition, in order to process glass containers, especially glass containers used for pharmaceuticals, a part of the length of the semi-finished tube is always wasted, and this part has a vent hole. After dividing by the length of the vial tube, the length of the remaining semi-finished tube is always will be less than the length of the vial

Embodiment Construction

[0031] figure 1 A schematic diagram of a longitudinal section of a semi-finished tube 1 according to the invention is shown for the production of glass containers 2, such as glass vials, glass ampoules or glass syringes, and is especially suitable for pharmaceutical use. Shown is a longitudinal section through a semi-finished pipe 1 . It has two end regions, namely a first end region 3 and a second end region 4 . Here the first end region 3 is closed. For this purpose, a base 6 is provided directly on the pipe end 5 . The base can now protrude, as shown, into the semi-finished tube interior 7 delimited by the walls of the base. It is also conceivable that the bottom 6 is flat (not shown here). Furthermore, according to the invention, the semi-finished tube 1 is open in the second end region 4 . Furthermore, the semi-finished tube 1 has a vent hole 8 which is machined into the wall 9 of the semi-finished tube 1 and is preferably located in the vicinity of the bottom 6 . T...

Abstract

A tube blank is disclosed for producing glass receptacles, in particular glass tube vials, glass ampules, or glass syringes, particularly those suitable for pharmaceutical applications, having a tube wall, including two end regions-a first end region and the second end region-the first end region being sealed to form a floor and a ventilation hole being introduced into the tube wall in the region of the end region, distinguished in that the tube end characterizing the second end region has an opening.

Description

technical field [0001] The invention relates to a semi-finished tube which can be used to manufacture glass containers, in particular glass tube vials, glass ampoules or glass syringes in the pharmaceutical field. Furthermore, the invention relates to a method for producing a glass container, in particular for the injection of medicines, from the semi-finished tube. Background technique [0002] European patent document EP-B-111 710 discloses a method of manufacturing glass tube vials from glass semi-finished tubes. The semi-finished glass tube here consists of a continuous glass tube. For this purpose, a glass tube section with the length of the glass tube is cut off from the glass tube and softened at both ends. The two softened ends are then pulled axially outward until the glass tube collapses in this area, thereby resulting in a closed tube end. A spot-shaped hole is provided next to one of the closed tube ends, and the thus prefabricated semi-finished tube of a cert...
