Method and facility for producing a glass vial

摘要

The method for fabrication of a glass vial (1) comprising a body (2) including a bottom (4) and side walls (3), comprises depositing a gob of glass in a cavity of a first half-shell and a second half-shell of a blank mold, where the cavity has a shape corresponding to an outer shape of half-bodies (2a, 2b) of the body, forming the half-bodies in the cavity of each first and second half-shell by applying punches to distribute the glass in the corresponding cavity and to define walls of the half-bodies, and forming a relief or recessed pattern on an inner face of a wall of the half bodies. The method for fabrication of a glass vial (1) comprising a body (2) including a bottom (4) and side walls (3), comprises depositing a gob of glass in a cavity of a first half-shell and a second half-shell of a blank mold, where the cavity has a shape corresponding to an outer shape of half-bodies (2a, 2b) of the body, forming the half-bodies in the cavity of each first and second half-shell by applying punches to distribute the glass in the corresponding cavity and to define walls of the half-bodies, forming a relief or recessed pattern on an inner face of a wall of the half bodies using the punches, and connecting edges of the two half-bodies with each other by exerting a certain pressure for heat sealing the edges with each other and for obtaining the glass vial. The half-bodies are provided with a ring (6). The method further comprises: transferring the two half-bodies into a finishing mold; extracting the two half-bodies of the half-shells of the blank mold; and blowing air inside the body. The connecting step is performed by heating the edges of the two half-bodies. An independent claim is included for an installation for the fabrication of a glass vial.
