Abstract

A method of sealing a container including a container and a closure member for sealing the container over a range of internal pressure.

Claims (27)

1. A method of sealing a container comprising:

providing a container defining a central longitudinal axis and a second axis intersecting said central longitudinal axis, wherein said second axis extends perpendicular to said central longitudinal axis, said container comprising:

a container interior within said container;

a container exterior oppositely disposed with respect to said container interior;

an opening providing fluid communication between said container interior and said container exterior;

a first sealing surface at least a portion of which lies on a third axis formed on said container exterior, wherein said third axis extends transverse to said second axis;

providing a closure member comprising:

a first wall portion comprising a first wall portion first surface;

a second wall portion extending from said first wall portion, said second wall portion comprising a second wall portion first surface;

dispensing a quantity of a liquid into said container interior;

moving said closure member into contact with said container;

causing at least a portion of said second wall portion first surface to sealingly engage said first sealing surface;

exposing at least a portion of said first wall portion first surface to said quantity of said liquid;

wherein said providing said container comprises providing said container further comprising:

a second sealing surface at least a portion of which lies on a fourth axis formed on said container exterior, wherein said fourth axis extends transverse to said central longitudinal axis;

wherein said providing said closure member comprises providing said closure member further comprising:

a third wall portion extending from second wall portion, said third wall portion comprising a third wall portion first surface; and

wherein at least a portion of said third wall portion first surface is adjacent to said second sealing surface said container defines a first direction extending along said central longitudinal axis from said opening toward said container interior;

wherein, a first vertex is located at an intersection of said third axis and said central longitudinal axis; and

wherein, said first vertex resides in said first direction from said opening.

2. The method of sealing a container of claim 1 wherein:

said container exterior is at an ambient pressure;

said container interior is at an internal pressure; and

said internal pressure is at least 10 pounds per square inch greater than said ambient pressure.

3. The method of sealing a container of claim 1 wherein, a first angle is formed between said first sealing surface and said central longitudinal axis; and

wherein, said first angle is less than 10 degrees.

4. The method of sealing a container of claim 1 wherein said container further defines an acute angle formed between said fourth axis and said second axis.
