Abstract

Disclosed are beverage containers and closures for beverage containers that are vented for the purpose of reducing negative pressure or vacuum that builds up inside the container when a beverage is being consumed therefrom. Also disclosed are closures which provide for chemical treatment of a liquid by a porous treatment matrix when the liquid is dispensed through the closure.

Claims

1-17. -17. (canceled)

18. A closure for dispensing fluids from a container, comprising:

a pair of telescopically coupled first and second members cooperatively defining a fluid path,

wherein said first member is attached to a base adapted to be secured to a container,

wherein the base and/or the first member include one or more sections of a porous vent material which allows passage of gases and inhibits bulk passage of liquid,

wherein the one or more sections of porous vent material are disposed on the first member, and

wherein the porous vent material is covered by the second member when the closure is in a closed position and exposed to air when the closure is in an open position.

19. (canceled)

20. A closure for dispensing fluids from a container, comprising:

a pair of telescopically coupled first and second members cooperatively defining a fluid path,

wherein said first member is attached to a base adapted to be secured to a container,

wherein the base and/or the first member include one or more sections of a porous vent material which allows passage of gases and inhibits bulk passage of liquid, and

wherein the base comprises a containing wall generally perpendicular to and surrounding the first member.

21. A closure according to claim 20, wherein the one or more sections of porous vent material are disposed on the containing wall portion of the base.

22. A closure according to claim 20, wherein the base is adapted to couple with the top of an aluminum beverage can.
