Vented closures for containers
First Claim
Patent Images
1. A closure for dispensing fluids from a container, comprising:
- a pair of telescopically coupled first and second members cooperatively defining a fluid path;
said first member 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.

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.

23. A closure for treating and dispensing a liquid, comprising:
-
a base adapted to secure the closure to a container;
a liquid path through the base through which liquid passes when the closure in use;
a porous treatment matrix contained within or connected to the liquid path, through which liquid passes when the closure is in use; and
a porous venting matrix secured to the base, wherein said porous venting matrix allows for passage of gases through the porous venting matrix and inhibits passage of liquid through the porous venting matrix thereby allowing for equalization of air pressure between a first location in contact with a first portion of said porous venting matrix and a second location in contact with a second portion of said porous venting matrix;
wherein said closure, when secured to a container during use, provides chemical treatment to a liquid as it passes said through said closure. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A closure for dispensing a liquid, comprising:
-
a base comprising means to secure the closure to a container;
a liquid path through the base through which liquid passes when the closure in use; and
a porous flow matrix having a high liquid flux rate and a low water intrusion pressure contained within or connected to the liquid path, through which liquid passes when the closure is in use;
wherein the porous flow matrix substantially prevents flow of liquid through the closure when the air pressure on opposing ends of the matrix are substantially equal. - View Dependent Claims (37, 38, 39, 40, 41, 50)

42. A beverage dispensing assembly, comprising:
-
a cap having an opening therein to allow flow of liquid and gas; and
a base housing adapted to be secured to a container; and
a generally hydrophobic porous vent material having a high water intrusion pressure contained within or connected to said base housing;
wherein the base housing and cap are movably coupled and cooperatively define a liquid path; and
wherein during use, vented air passing into the container follows a central axis around which the liquid flows as it passes out of the container and through the dispenser, thereby reducing air entrainment in the dispensed liquid. - View Dependent Claims (43, 44, 45, 46, 47, 48, 49, 51, 52, 53)
