Abstract

A plastic, hot-fillable container is provided. The container comprises a blow molded body defining a longitudinal axis. The body including a base and a neck having at least one rib disposed about at least a portion of a circumference of the neck and transverse to the axis, and at least one angled thread. The at least one rib defining a cross section having a first portion and a second angled portion. Container systems and methods of manufacturing containers are disclosed.

First claim

What is claimed is:

1. A container defining a longitudinal axis, the container including a base and a neck extending from the base, the container having a thread extending about the neck, the thread defining a plurality of projections, the projections being aligned along a line that extends at an acute angle relative to the longitudinal axis.

2. The container recited in claim 1 , wherein the projections are spaced apart from one another.

3. The container recited in claim 1 , wherein the thread is an angled thread.

4. The container recited in claim 3 , wherein the angled thread extends at the acute angle relative to the longitudinal axis.

5. The container recited in claim 1 , wherein the thread comprises a plurality of angled threads, the angled threads each including a plurality of the projections.

6. The container recited in claim 5 , wherein the angled threads are spaced apart from one another.

7. The container recited in claim 5 , wherein at least one of the angled threads extends at the acute angle relative to the longitudinal axis.

8. The container recited in claim 1 , wherein the thread comprises a five spaced apart angled threads, the angled threads each including a plurality of the projections.

9. The container recited in claim 8 , wherein the angled threads are spaced apart from one another.

10. The container recited in claim 8 , wherein at least one of the angled threads extends at the acute angle relative to the longitudinal axis.

11. The container recited in claim 1 , wherein the projections are oriented on an upper portion of the thread.

12. The container recited in claim 1 , wherein container is a plastic, hot-fillable container.

13. The container recited in claim 1 , wherein the container comprises a body that includes the base and the neck, the body being a blow molded body.

14. The container recited in claim 1 , wherein the thread includes a plurality of spaced apart threads, the container further comprising a metal closure having a plurality of inwardly facing tabs engageable with the threads.

15. The container recited in claim 14 , wherein the threads are angled threads.

16. The container recited in claim 1 , wherein the base comprises a vertical wall and a horizontal bottom panel extending from the vertical wall, the bottom panel being configured to move outwardly and inwardly relative to the vertical wall during pressure and vacuum application.

17. The container recited in claim 16 , wherein the panel includes a circular center portion and a plurality of spaced apart radial segments.

18. The container recited in claim 17 , wherein the center portion resists deformation when moving inwardly and outwardly on the panel relative to a body of the container during pressure and vacuum application.

19. A container comprising:
a plastic body defining a longitudinal axis, the body including a base and a neck extending from the base, the container having a plurality of angled thread extending about the neck, the threads each defining a plurality of spaced apart projections, the projections of a respective one of the threads being aligned along a line that extends at an acute angle relative to the longitudinal axis; and
a metal closure having a plurality of inwardly facing tabs engageable with the threads.

20. A container comprising:
a body defining a longitudinal axis, the body including a base and a neck extending from the base, the container having a plurality of angled threads extending about the neck, the threads each defining a plurality of spaced apart projections, the projections of a respective one of the threads being aligned along a line that extends at an acute angle relative to the longitudinal axis,
wherein the base comprises a vertical wall and a horizontal bottom panel extending from the vertical wall, the bottom panel being configured to move outwardly and inwardly relative to the vertical wall during pressure and vacuum application,
wherein the panel includes a circular center portion and a plurality of spaced apart radial segments, and
wherein the center portion resists deformation when moving inwardly and outwardly on the panel relative to a body of the container during pressure and vacuum application.
