Abstract: A glass container is characterized by a longitudinal axis (Ltube) that passes through a center of a glass bottom of the glass container. For any cut surface of the glass container that is obtainable by cutting the glass container in a plane that includes the longitudinal axis Ltube, a minimum thickness (smin) and a maximum thickness (smax) of the glass bottom determined at any position having a distance d1/4 or less to the longitudinal axis Ltube and a thickness (sd1/4) is the thickness of the glass bottom determined at a position having the distance d1/4 to the longitudinal axis Ltube, the distance to the longitudinal axis Ltube in each case being determined in a direction that is perpendicular to the longitudinal axis Ltube and thicknesses smin, smax and sd1/4 being determined in a direction that is parallel to longitudinal axis Ltube, with smax/smin being less than 1.8.

Abstract: A process for the preparation of a glass container from a glass tube in a glass processing machine includes the steps of: I) heating the glass tube at a defined position between a first portion and a second portion to a temperature above a glass transition temperature of the glass tube while the glass tube is rotating around its longitudinal axis Ltube and pulling apart the first portion and the second portion thereby separating the first portion from the second portion and forming a closed bottom at one end of the first portion; and II) moving a mold matrix of the glass processing machine towards the closed bottom and bringing the mold matrix into contact with the closed bottom. While bringing the mold matrix into contact with the closed bottom, a distance Ym between the mold matrix and a first clamping chuck of the glass processing machine is decreased stepwise.

Abstract: A glass container includes a body region with a first end and a second end, the body region having an outer diameter (d1) and a glass thickness (s1), the body region being characterized by a longitudinal axis (Ltube) that passes through a center of the first and second end. When the glass container is standing on a support surface, h2 is the distance between the support surface up to the second end of the body region. The following condition is fulfilled: (A×X)/B=C. A is an axial load necessary to break the glass container to obtain fragments, X is a normalized area in cm2 defined as h2×d1×?+d12/4×?, B is a number of fragments of the glass container, and C is a fracture ratio. C is 40 N×cm2 or more and B is 30 or more.

Abstract: 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 dw and an outer diameter dc, a glass bottom with an outer area, the glass bottom closes the glass tube at the first end, and 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 ro, an inner radius ri, and a thickness of the glass dh in the curved glass heel and: [100×(dh3×ri)/(dw ×dc2)]+(4.4 mm2/dc)>0.55 mm.
