Abstract
A blow nozzle for supplying compressed air to the internal cavity of a preform, the blow nozzle including a tube having a first layer, a second layer, and a third layer, the first layer being radially wider and having a larger diameter than the second layer, the second layer being disposed between the first and third layers, and the second layer being radially wider and having a larger diameter than the third, and a plurality of holes disposed on the third layer for directional blowing of the compressed air into the preform, when the nozzle is inserted into a neck opening of the preform and rests in a blow molding position.
Claims18
A blow nozzle for supplying compressed air to the internal cavity of a preform, the blow nozzle comprising:
- a tube comprising a first layer, a second layer, and a third layer, the first layer being radially wider and having a larger diameter than the second layer, the second layer being disposed between the first and third layers, and the second layer being radially wider and having a larger diameter than the third layer;
- a plurality of holes disposed on the third layer for directional blowing of the compressed air into the preform, when the nozzle is inserted into a neck opening of the preform and rests in a blow molding position;
- and
- a beveled portion of the tube at the bottom of the third layer, the beveled portion of the tube comprising the plurality of holes disposed at an angle,
- wherein the compressed air flows downward from the first layer to the second layer and then out through the beveled portion of the third layer.

A method for inflating a container from a preform using a blow nozzle, comprising:
- obtaining a blow nozzle comprising:
- a tube comprising a first layer, a second layer, and a third layer, the first layer being radially wider and having a larger diameter than the second layer, the second layer being disposed between the first and third layers, and the second layer being radially wider and having a larger diameter than the third, and
- a plurality of holes disposed on the third layer of the blow nozzle for directional blowing of the compressed air into the preform;
- inserting the blow nozzle into the preform into a blow molding position such that the bottom of the third layer of the blow nozzle is between an upper attachment point of a handle of the preform and a lower attachment point of the handle, just below the upper attachment point of the handle;
- and
- flowing compressed air through the plurality of holes of the blow nozzle such that the plurality of holes facilitates directional blowing of the compressed air to form the container.
A blow nozzle for supplying compressed air to the internal cavity of a preform, the blow nozzle comprising:
- a tube comprising a first layer, a second layer, and a third layer, the first layer being radially wider and having a larger diameter than the second layer, the second layer being disposed between the first and third layers, and the second layer being radially wider and having a larger diameter than the third layer;
- and
- a plurality of holes disposed on the third layer for directional blowing of the compressed air into the preform, when the nozzle is inserted into a neck opening of the preform and rests in a blow molding position,
- wherein the plurality of holes are randomly distributed across the third layer of the nozzle tube.
