Method of fabricating a glass container, and a corresponding installation for performing the method
The invention relates to a method of fabricating a glass container, the method comprising a forming step of forming molten glass in order to obtain a semi-finished container (4) comprising a shell (5) presenting inside and outside faces (7, 8), a cooling step during which the semi-finished container is in a transient state in which the glass forming the outside face is sufficiently viscous for it not to deform under the effect of gravity, while the glass forming the inside face is sufficiently fluid to allow the inside face to deform under the effect of gravity, the method including a shaping operation while the semi-finished container is in the transient state, in which operation the semi-finished container is maintained for a predetermined time in a position that is inclined relative to its upright vertical position in order to modify the shape of the inside face under the effect of gravity.

The invention relates to a method of fabricating a glass container, the method comprising a forming step of forming molten glass in order to obtain a semi-finished container (4) comprising a shell (5) presenting inside and outside faces (7, 8), a cooling step during which said semi-finished container is in a transient state in which the glass forming said outside face is sufficiently viscous for it not to deform under the effect of gravity, while the glass forming said inside face is sufficiently fluid to allow said inside face to deform under the effect of gravity, said method including a shaping operation while the semi-finished container is in said transient state, in which operation the semi-finished container is maintained for a predetermined time in a position that is inclined relative to its upright vertical position in order to modify the shape of said inside face under the effect of gravity.
A method of fabricating glass containers, and a corresponding fabrication installation.
Method and equipment for manufacturing a thin, hollow glass item
The invention relates to a method, comprising: feeding at least one molten-glass parison into a parison mold; forming, in the parison mold, a blank of an item from said at least one parison; transferring the blank of the item into a finishing mold; and forming the item in the finishing mold. While forming the item in the finishing mold, excess glass is directed out of the base of the item so as to form a convex bulge, and said bulge is removed such that the thickness of the base of the item is substantially constant.
