Method of sealing a container

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.
