A fluid container including a container having an opening and a spout assembly connected to the opening. The spout assembly is connectable to the opening. The spout assembly includes a cap, first and second tubular portions, and at least one corrugated portion. The cap is securable so as to substantially cover the opening. The first tubular portion is connected to the cap. The at least one corrugated portion is fluidically coupled between the first tubular portion and the second tubular portion. The second tubular portion being insertable into the first tubular portion.
1. A fluid container, comprising:
a container having an opening; and
a spout assembly connectable to said opening, said spout assembly including:
a cap securable to substantially cover said opening;
a first tubular portion connected to said cap;
a second tubular portion; and
at least one corrugated portion fluidically coupled between said first tubular portion and said second tubular portion, said second tubular portion being insertable into said first tubular portion, said cap having internal threads, said second tubular portion being inserteable into said first tubular portion to such an extent that at least one corrugation of said at least one corrugated portion contacts said internal threads.
2. The fluid container of claim 1 , wherein said spout assembly further includes a third tubular portion, said at least one corrugated portion including a first corrugated portion and a second corrugated portion, said first corrugated portion being connected to said first tubular portion and said third tubular portion, said second corrugated portion being connected between said second tubular portion and said third tubular portion.
3. The fluid container of claim 2 , wherein said first tubular section has a first diameter, said second tubular section has a second diameter, said third tubular section has a third diameter, said second diameter being less than said first diameter.
4. The fluid container of claim 3 , wherein said third diameter is less than said first diameter and said third diameter being larger than said second diameter.
5. The fluid container of claim 1 , wherein said contact of said at least one corrugation with said internal threads is a flexible interference contact between said at least one corrugation and said internal threads.
6. The fluid container of claim 1 , wherein said second tubular portion is configured to be substantially insertable into said first tubular portion when said cap is not secured to said opening.
7. The fluid container of claim 1 , wherein said spout assembly includes a duckbill valve connected to a portion of said cap.
8. A spout assembly connectable to an opening of a fluid container, said spout assembly comprising:
a cap securable to substantially cover said opening;
a first tubular portion connected to said cap;
a second tubular portion; and
at least one corrugated portion fluidically coupled between said first tubular portion and said second tubular portion, said second tubular portion being insertable into said first tubular portion, said cap has internal threads, said second tubular portion being inserteable into said first tubular portion to such an extent that at least one corrugation of said at least one corrugated portion contacts said internal threads.
9. The spout assembly of claim 8 , further comprising a third tubular portion, said at least one corrugated portion including a first corrugated portion and a second corrugated portion, said first corrugated portion being connected to said first tubular portion and said third tubular portion, said second corrugated portion being connected between said second tubular portion and said third tubular portion.
10. The spout assembly of claim 9 , wherein said first tubular section has a first diameter, said second tubular section has a second diameter, said third tubular section has a third diameter, said second diameter being less than said first diameter.
11. The spout assembly of claim 10 , wherein said third diameter is less than said first diameter and said third diameter being larger than said second diameter.
12. The spout assembly of claim 8 , wherein said contact of said at least one corrugation with said internal threads is a flexible interference contact between said at least one corrugation and said internal threads.
13. The spout assembly of claim 8 , wherein said second tubular portion is configured to be substantially insertable into said first tubular portion when said cap is not secured to said opening.
14. The spout assembly of claim 8 , further comprising a duckbill valve connected to a portion of said cap.
15. A method of nesting ends of a spout assembly, comprising the steps of:
substantially inserting a second tubular portion of a spout into a first tubular portion of the spout; and
interfering a portion of the spout assembly with an other portion of the spout assembly to thereby retain said second tubular portion inside of said first tubular portion, said portion of the spout assembly is threads of a cap, and said other portion is a corrugation adjacent said second tubular portion.
16. The method of claim 15 , wherein said second tubular portion has an outer diameter that is smaller than an inner diameter of said first tubular portion.
17. The method of claim 15 , wherein said portion of the spout assembly is a distal end of said second tubular portion, and said other portion is a corrugation adjacent said first tubular portion.
