Glass articles made from laminated glass tubing and systems and methods for converting laminated glass tubing into the glass articles
Methods for producing glass articles from laminated glass tubing include introducing the glass tubing to a converter. The glass tubing includes a core layer under tensile stress, an outer clad layer under, and an inner clad layer. The methods include forming a feature the glass article at a working end of the laminated glass tubing and separating a glass article from the working end of the laminated glass tubing, which may expose the core layer under tensile stress at the working end of the glass tubing. The method further comprises remediating the exposed portion of the core layer by completely enclosing the core layer in a clad layer. Systems for re-cladding the exposed portion of the core layer as well as glass articles made using the systems and methods are also disclosed.
Method For Reducing or Eliminating Residue in a Glass Container and a Glass Container made in Accordance Therewith
A method of preparing a glass medical container is provided including the steps of providing a glass blank and forming a channel through a part of the glass blank, the channel being substantially free of tungsten or derivatives thereof. In a further aspect of the subject invention, a glass medical container is provided including a glass body having a channel extending through a part of the glass body, the channel being substantially free of tungsten or derivatives thereof. With the subject invention, tungsten or derivatives thereof can be generally or altogether completely avoided in glass medical containers.

Glass container with an improved bottom geometry
A glass container for packaging a pharmaceutical composition including a glass tube with a first end and a second end, the glass tube having a wall thickness d.sub.w, a glass bottom having an outer area, and the glass bottom closes the glass tube at the first end. The glass container further including a curved glass heel extending from the outer area of the glass bottom to the first end of the glass tube. The curved glass heel is defined by an outer radius r.sub.o, an inner radius r.sub.i and a thickness of the glass d.sub.h in the curved glass heel, further wherein d.sub.h.sup.3/(r.sub.o×d.sub.w)>0.8 mm.
Device and method for producing a medical glass container
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.
Methods for minimizing SHR in glass articles by producing a gas flow during pharmaceutical part converting
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.
Tapered glass tip for use with smokable substances contained within a wrap and method for manufacturing the tip
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.
VIAL WITH OPTIMIZED NECK FOR IMPROVED SIDE COMPRESSION PERFORMANCE
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.
