Device for manufacturing a hollow glass article comprising a mold intended to receive a parison

A method for forming a hollow glass article from a parison, the article including a ring extending around an axis, a body and at least one shoulder extending between the ring and the body, the method comprising the steps of:

• receiving a parison of the article in a mold including a plurality of movable portions between a closed configuration, in which the portions define a first imprint forming the body of the article, and an open configuration in which the portions are moved away from each other for removing the article from the mold;
• and
• injecting at least one gas jet into the inside of the parison by a movable blowing head between a blowing position in which the blowing head is applied against the mold, and a rest position in which the blowing head is at a distance from the mold, the blowing head being in the blowing position during the injection, the blowing head including at least one face defining a second imprint forming at least one portion of the at least one shoulder in the blowing position while the at least one gas jet enters and inflates the parison, the parison assuming the shape of the first imprint and of the second imprint.
