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 provided.

First claim

What is claimed is:

1. A container defining a longitudinal axis and including a base and a neck extending from the base, the neck comprising spaced apart proximal and distal ribs and a plurality of threads positioned between the ribs, at least one of the threads extending at an acute angle relative to the longitudinal axis and comprising spaced apart projections extending therealong,
wherein the projections are oriented on upper portions of the threads.

2. The container recited in claim 1 , wherein the projections are aligned along a line that extends at the acute angle relative to the longitudinal axis.

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

4. The container recited in claim 1 , wherein each of the threads includes the projections.

5. The container recited in claim 1 , wherein the projections are circular in shape.

6. The container recited in claim 1 , wherein the ribs define a groove therebetween, the threads being positioned in the groove.

7. The container recited in claim 1 , wherein the projections are uniformly spaced apart.

8. The container recited in claim 1 , further comprising a cap including a gasket configured for engagement with the projections to facilitate sealing engagement of the cap with the threads.

9. The container recited in claim 1 , further comprising a cap including tabs configured for engagement with the projections to facilitate sealing engagement of the cap with the threads.

10. The container recited in claim 1 , wherein the container is a plastic container.

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

12. 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.

13. 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.

14. The container recited in claim 13 , wherein the panel includes a circular center portion and a plurality of spaced apart radial segments.

15. The container recited in claim 14 , 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.

16. A container comprising:
a plastic base extending along a longitudinal axis and a neck extending from the base, the neck comprising spaced apart proximal and distal ribs and a plurality of threads positioned between the ribs, at least one of the threads extending at an acute angle relative to the longitudinal axis and comprising spaced apart projections extending therealong; and
a cap including tabs configured for engagement with the projections to facilitate sealing engagement of the cap with the threads.

17. The container recited in claim 16 , wherein the cap is metal.

18. The container recited in claim 16 , wherein the tabs are inwardly facing.

19. A container defining a longitudinal axis and including a base and a neck extending from the base, the neck comprising spaced apart proximal and distal ribs and a plurality of threads positioned between the ribs, at least one of the threads extending at an acute angle relative to the longitudinal axis and comprising spaced apart projections extending therealong,
wherein the threads are spaced apart from one another.

20. The container recited in claim 19 , wherein the ribs define a groove therebetween, the threads being positioned in the groove.
