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 and including a base and a neck extending from the base, the neck comprising spaced apart 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, the projections facing away from the base.

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

3 . The container recited in claim 1 , wherein the ribs extend parallel to one another.

4 . The container recited in claim 1 , wherein the ribs each extend circumferentially about the neck.

5 . The container recited in claim 1 , wherein the ribs include a proximal rib and a distal rib, the distal rib having a diameter that is greater than a diameter of the proximal rib.

6 . The container recited in claim 1 , wherein the ribs include a proximal rib and a distal rib, the threads each including an upper portion that faces the proximal rib and a lower portion that faces the distal rib, the projections being oriented on the upper portions.

7 . 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.

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

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

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

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

12 . 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.

13 . 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.

14 . 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.

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

16 . The container recited in claim 15 , 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.

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

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

19 . The container recited in claim 17 , wherein the tabs are inwardly facing.

20 . A container comprising:
a base; a neck extending from the base, the neck comprising spaced apart ribs and a plurality of threads positioned between the ribs, the threads extending at an acute angle relative to at least one of the ribs and comprising spaced apart projections extending therealong, the projections facing away from the base; and a cap including a gasket configured for engagement with the projections to facilitate sealing engagement of the cap with the threads.
