Abstract

A glass container forming apparatus for forming a glass parison is disclosed. The glass container forming apparatus includes a feeder spout having a heated orifice ring, a plunger carried in the feeder spout and having a blow conduit therethrough, and die rollers immediately downstream of the heated orifice ring, with no chutes, scoops, or other gob handling devices therebetween. A glass container forming system that includes a glass feeder and a glass container forming apparatus is also disclosed.

First claim

The invention claimed is:

1. A glass container forming apparatus, comprising:
a feeder spout including a heated orifice ring;
a plunger carried in the feeder spout and including a blow conduit therethrough; and
die rollers immediately downstream of the heated orifice ring, with no chutes, scoops, or other gob handling devices therebetween, wherein the die rollers include polyhedrons carrying at least one cavity on each face for forming glass containers from a continuous tube of molten glass, wherein the die rollers are configured to form a continuous string of glass containers with each of the glass containers having at least one open end.

2. The apparatus of claim 1 , wherein the plunger includes a screw plunger.

3. The apparatus of claim 1 , wherein the at least one cavity is configured to form at least one of a handle or a finger hook on the glass containers.

4. The apparatus of claim 1 , wherein the die rollers include two die rollers.

5. The apparatus of claim 1 , wherein the die rollers include four die rollers.

6. The apparatus of claim 1 , further comprising:
a vacuum manifold coupled to the die rollers and configured to assist with shaping glass containers.

7. The apparatus of claim 6 , wherein the vacuum manifold is a stationary vacuum manifold.

8. The apparatus of claim 1 , further comprising:
a cooling bath in cooling contact with at least a portion of the die rollers.

9. The apparatus of claim 1 , wherein the plunger is configured to push molten glass through the heated orifice ring and the blow conduit is configured to receive compressed air.

10. A glass container forming system, comprising:
a glass feeder; and
glass container forming apparatus configured to receive molten glass from the glass feeder, the glass container forming apparatus including
a feeder spout including a heated orifice ring;
a plunger carried in the feeder spout and including a blow conduit therethrough; and
die rollers immediately downstream of the heated orifice ring, with no chutes, scoops, or other gob handling devices therebetween, wherein the die rollers include polyhedrons carrying at least one cavity on each face for forming glass containers from a continuous tube of molten glass, wherein the die rollers are configured to form a continuous string of glass containers with each of the glass containers having at least one open end.
