A glass container is provided having a glass tube with a first end and a second end and a glass bottom closing the second end. The glass tube has a longitudinal axis and has, in a direction from the first to the second end, a top region, a junction region, a neck region, a shoulder region, and a body region. The top region is at the first end and has an outer diameter (d.sub.t), the neck region has an outer diameter (d.sub.n) with d.sub.n<d.sub.t, the body region extends to the second end and has an outer diameter (d.sub.b) with d.sub.b>d.sub.t, and the glass tube in the body region has a thickness (l.sub.b). The outer contour in a transition area between the top and neck regions is defined by a radius of curvature. The glass containers have a neck squeeze test load of at least 1100 N.

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.

A method for shaping the mouth of a hollow precursor made of glass is provided, as well as glass produced thereby. The method includes heating the mouth of the hollow precursor; introducing a mandrel along a first direction into the mouth while the hollow precursor is rotating; and pressing shaping rollers along a second direction on an outside of the mouth while the hollow precursor is rotating with the mandrel in the mouth. The first and second directions are perpendicular to one another. The method can include moving the mandrel along second and/or third directions together or separate from expanding the mandrel along the second and third directions.

A device for producing a high-purity medical glass container from a hollow cylindrical glass blank extending along an axial direction (X) and having at least one open end, wherein the glass blank has a mouldable moulded section extending in the axial direction (X) from the open end. The device comprises a first moulding tool and a second moulding tool, where the first moulding tool has a moulding pin. The moulding pin can be moved via the open end of the hollow cylindrical glass blank in the moulded section thereof along the axial direction (X), wherein the moulding pin is fixed in a fixing unit of the first moulding tool. The moulded section can be deformed by the second moulding tool in such a way that an inner surface of the moulded section is in contact with the moulding pin, whereby the moulded section forms a channel.

A method of manufacturing a tip for use with smokeable substances. A tube is rotated while applying heat to a section. The heated section is squeezed with tapered rollers and a pivoting rod is inserted. The rollers and rod are removed and heat is again applied. The heated portion is squeezed a second time with the tapered rollers and the rod is reinserted. The rollers and rod are removed and heat is again applied. The heated portion is again squeezed with the tapered rollers and the pivoting rod is again reinserted. The rollers and rod are removed and heat is applied to the end of the tube. The tube is scored above the end to form a scored line. Heat is applied to the scored line. Water is sprayed onto the scored line to split the tube into two pieces. Heat is applied to the tube at the split end.

A glass container is provided having a glass tube with a first end and a second end and a glass bottom closing the second end. The glass tube has a longitudinal axis and has, in a direction from the first to the second end, a top region, a junction region, a neck region, a shoulder region, and a body region. The top region is at the first end and has an outer diameter (d.sub.t), the neck region has an outer diameter (d.sub.n) with d.sub.n<d.sub.t, the body region extends to the second end and has an outer diameter (d.sub.b) with d.sub.b>d.sub.t, and the glass tube in the body region has a thickness (l.sub.b). The outer contour in a transition area between the top and neck regions is defined by a radius of curvature. The glass containers have a neck squeeze test load of at least 1100 N.

A device for the shaping of glass bodies, in particular of pharmaceutical vials, comprises a clamping chuck for holding a glass body, a rotary drive for driving the clamping chuck rotatingly, further at least one heat source for heating a glass body held within the clamping chuck, and further a controller which is coupled to the rotary drive so that the clamping chuck can be driven at variable rotational speed.

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 hot-forming tool for producing glass containers is provided. The tool includes a forming roller, a holder, and a heat sink. The forming roller has a forming surface. The holder receives the forming roller with the forming roller rotatably mounted on the holder. The heat sink is directly or indirectly connected to the holder. The forming roller is in thermal contact with the heat sink and the heat sink has an internal cooler so that process heat can be transferred from the forming roller to the heat sink.
