## Abstract

A method of making a bottle includes (a) forming a parison, (b) blowing the parison into a bottle of one-piece integrally formed construction, and (c) during the step (a) and/or the step (b), forming internal features on a neck of the bottle. Step (c) includes (c1) forming external features on the neck during the step (a), (c2) pushing the external features into the neck during step (b), and forming the internal features to be disposed entirely within the neck where the neck widens and at positions spaced from an internal surface of a neck finish and not extending into a shoulder of the bottle.

## Claims

### Claim 1

A method of making a bottle having a body with a closed base and a shoulder at an end of said body remote from said base, and a neck extending from said shoulder along an axis and terminating in a neck finish for attachment of a closure, wherein said neck widens between said neck finish and said shoulder, said method including the steps of:
(a) forming a parison,
(b) blowing said parison into a bottle of one-piece integrally formed construction, and
(c) during said step (a) and/or said step (b), forming internal features on said neck,
wherein said step (c) includes:
(c1) forming external features on said neck during said step (a), and
(c2) pushing said external features into said neck during said step (b),
wherein said step (c) further includes forming said internal features to be disposed entirely within said neck where said neck widens and at positions spaced from an internal surface of said finish and not extending into said shoulder.

### Claim 2 (depends on 1)

The method set forth in claim 1 wherein said internal features are integrally formed with and extend inwardly from an inside surface of said neck.

### Claim 3 (depends on 1)

The method set forth in claim 1 wherein said features formed in step (c) include at least one internal rib.

### Claim 4 (depends on 3)

The method set forth in claim 3 wherein said at least one internal rib includes at least one spiral rib around said axis, or at least one elliptical rib in a plane at an angle to said axis, or at least one longitudinal rib coplanar with said axis, or at least one annular rib in a plane perpendicular to said axis.

### Claim 5 (depends on 3)

The method set forth in claim 3 wherein said at least one internal rib is spiral.

### Claim 6 (depends on 3)

The method set forth in claim 3 wherein said at least one internal rib is elliptical.

### Claim 7 (depends on 3)

The method set forth in claim 3 wherein said at least one internal rib includes a plurality of elliptical ribs disposed in parallel planes spaced from each other along said axis.

### Claim 8 (depends on 3)

The method set forth in claim 3 wherein said at least one internal rib is circular.

### Claim 9 (depends on 3)

The method set forth in claim 3 wherein said at least one internal rib is longitudinal.

### Claim 10 (depends on 1)

The method set forth in claim 1 wherein said bottle is a glass longneck bottle.

### Claim 11 (depends on 1)

The method set forth in claim 1 wherein step (c) further includes:
(c3) forming at least one external channel in said neck and a corresponding internal rib on said neck.
