Abstract
A method for manufacturing a hollow glass is provided. The method includes the steps of placing at least one drop of glass in a cavity of a mold, inserting a punch into the cavity of the mold, forming the hollow glass item by using the punch and simultaneously imprinting at least one raised or hollow pattern at a chosen location on an inner surface of at least one wall of the hollow glass item, thereby superimposing the at least one raised or hollow pattern on the shape of the hollow glass item, removing the punch from the cavity of the mold and stripping the hollow glass item, which includes the at least one inner raised and/or hollow pattern. The punch has a body with an end portion, the end portion has an outer side surface. The body includes a raised or hollow pattern on the outer side surface of the end portion. The raised or hollow pattern is independent of the shape of the hollow glass item. A device for manufacturing a hollow glass item is also provided.
