Abstract

Abstract The invention provides an improved packaging system for beverages, the system comprising a beverage container having an integral straw permitting automatic emergence of the straw when a pull tab is separated from the container. In one embodied form, the flexible, resilient straw is held internally within the container by a retaining collar member which is suitably secured to the underside of the pull tab to hold the straw in a deformed condition when the pull tab is not yet separated from the container. In a preferred embodied form, the straw comprises an upper corrugated portion to permit prescribed resiliency and adjustment of length when internally positioned within the container. Accordingly, the present invention provides a unique convenient packaging system for beverages which enhances safety and hygienic features of conventional pull tab beverage containers at a relatively modest production cost.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 244 words
An improved packaging system for beverages, the system comprising a beverage container having, at a top portion, a pull tab and a pull ring; said pull tab and pull ring being joined by anchoring means; wherein when separated along the weakened seam said ring cooperates with said tab to produce a drinking opening in said container top portion; an integral, flexible, resilient, tubular drinking straw disposed internally of said beverage container; and a resilient collar member disposed on the underside of said tab for holding said drinking straw in a deformed condition internally of said container when said pull tab is not separated from said container top portion; said collar member comprising a top collar portion which is received and joined within a hollow disposed in the underside of said anchoring means, said collar member further comprising two resilient legs to surround a majority of the circumferential surface of said tubular drinking straw except for a minor portion sufficient to enable said drinking straw to slip therethrough; said retaining collar member being of a diameter sufficient to receive and to substantially envelope an upper portion of said drinking straw when threaded through said collar member; wherein said retaining collar member cooperates with said drinking straw to hold said straw in a deformed condition when said pull tab is not separated from said container top portion and causes automatic emergence of said drinking straw when said pull tab is separated from said container top portion.
Claim 2
Dependent Claim 244 words
An improved packaging system for beverages, the system comprising a beverage container having, at a top portion, a pull tab and a pull ring; said pull tab and pull ring being joined by anchoring means; wherein when separated along the weakened seam said ring cooperates with said tab to produce a drinking opening in said container top portion; an integral, flexible, resilient, tubular drinking straw disposed internally of said beverage container; and a resilient collar member disposed on the underside of said tab for holding said drinking straw in a deformed condition internally of said container when said pull tab is not separated from said container top portion; said collar member comprising a top collar portion which is received and joined within a hollow disposed in the underside of said anchoring means, said collar member further comprising two resilient legs to surround a majority of the circumferential surface of said tubular drinking straw except for a minor portion sufficient to enable said drinking straw to slip therethrough; said retaining collar member being of a diameter sufficient to receive and to substantially envelope an upper portion of said drinking straw when threaded through said collar member; wherein said retaining collar member cooperates with said drinking straw to hold said straw in a deformed condition when said pull tab is not separated from said container top portion and causes automatic emergence of said drinking straw when said pull tab is separated from said container top portion.
Claim 3
Dependent Claim 18 words
The improved packaging system as defined in claim 1 wherein said drinking straw comprises an upper corrugated portion.
Claim 4
Dependent Claim 65 words
The improved packaging system as defined in claim 1 wherein the resilient force of said drinking straw is complimentary with the retaining force exerted by the retaining collar member such that when said pull tab is separated from said container top portion, said drinking straw slips through said radial slot disposed on said collar member to emerge in a free-standing fashion in said drinking opening.
Claim 5
Dependent Claim 17 words
The improved packaging system as defined in claim 1 wherein said beverage container is fabricated from aluminum.
Claim 6
Dependent Claim 17 words
The improved packaging system as defined in claim 1 wherein said drinking straw is fabricated from plastic.
Claim 7
Dependent Claim 27 words
The improved packaging system as defined in claim 1 wherein said collar member is joined to said pull tab and said pull ring by a common rivet.
Claim 8
Dependent Claim 17 words
The improved packaging system as defined in claim 1 wherein said collar member is fabricated from aluminum.
