A method for molding end portions on glass containers that store pharmaceutical active ingredients is provided. The glass containers are produced from a glass tube by hot-forming, an end portion having a neck opening using a centrally disposed opening forming tool interacting with a shaping tool at one end of the glass containers. In the method, dimensional data is provided for the respective glass tube and the position of the shaping tool is adjusted in a motorized manner in the axial direction (z) of the glass containers so as to correspond to the provided dimensional data for the respective glass tube.

A glass atomizer includes an atomizer housing, wherein: a diameter of the atomizer housing is 5.8-6.2 mm; a nozzle is formed at a top part of the atomizer housing; an outlet of the nozzle has a diameter of 2.4-2.5 mm; a limiting convex member is arranged at a bottom part of the atomizer housing; a conical hollow connection member is formed at an inner wall of the bottom part of the atomizer housing; a top part of the connection member extends upward and forms an atomizer core tube; the atomizer core tube and the atomizer housing are concentric; an inlet tube is integrally formed at a side of the atomizer housing; and a groove is opened at an outer wall of the inlet tube.

A glass container is provided that includes a tube, a circular bottom, and a longitudinal axis. A curved glass heel extends from an outer end the bottom to the first end of the tube. The outer surface has a topography defined by a function ?(x) that is an azimuthal average of a distance between a contact plane and the outer surface at any given position located on a circle having the centre and the radius |x|. The values ? for ?(x) are determined for a plurality of circles the radius of which increases stepwise by 500 ?m starting with a circle around the centre having a radius of 500 ?m. The values ? are determined in a range from x=?0.4?d2/2 to x=+0.4?d2/2, d2 having a size such that at least 4 values ? are determined and can be fitted with a curvature function $\hat{h}\left(x\right)=\frac{-c?x^2}{1+\sqrt{1-c^2?x^2}}+h_0.$

A positioning device for a preloading ring of a hot forming machine is provided. The device has a first holding element and a second holding element. The first holding element has a first recess and a second recess. The second recess is at a distance radially with respect the first recess. The second holding element is arranged in a region of and faces the first and second recess. The first and second holding elements are configured and arranged movably about respective axes with respect to each other so that movement towards each other encloses a glass tube in each of the first and second recesses and between the holding elements.

A method of forming a glass container including forming a glass container having a sidewall at least partially enclosing an interior volume, at least a portion of an interior surface of the sidewall having an interior surface layer; and contacting the glass container with a substantially fluoride-free aqueous treating medium to remove a thin layer of the interior surface layer having a thickness of from about 100 nm to about 1.0 m from the interior surface of the sidewall. The interior surface is resistant to delamination. Before contacting the glass container with the substantially fluoride-free aqueous treating medium, the exterior surface of the sidewall comprises strength-limiting surface flaws having a first shape, and after the contacting the exterior surface of the sidewall with the substantially fluoride-free aqueous treating medium, the strength-limiting surface flaws have a second shape.

Systems for producing articles from glass tube include a converter having a base with a plurality of processing stations and a turret moveable relative to the base. The turret indexes a plurality of holders for holding the glass tubes successively through the processing stations. The systems further include a gas flow system or a suction system for producing a flow of gas through the glass tube during one or more heating, forming, separating or piercing operations. The flow of gas through the glass tube produced by the gas flow system or suction system may be sufficient to evacuate or purge volatile constituents of the glass from the glass tube and/or pierce a meniscus formed on the glass tube during separation, thereby reducing the Surface Hydrolytic Response (SHR) of the interior surface of the glass tube and articles made therefrom.
