A fitment for package holding a liquid and a package including such a fitment. The fitment is a metering dispensing valve arranged to be secured to a flexible bag for selectively dispensing a metered quantity of the liquid therefrom. It includes a compressible bulb and a piercing member which when actuated pierces through the bag to enable a metered amount of the liquid to be drawn into a reservoir in the bulb. The bulb can then be compressed to dispense the metered amount of liquid from the reservoir. The dispensing valve also includes a inlet valve to the reservoir and an outlet valve from the reservoir. The fitment may include a pair of barriers to enable it to be sterilized before being secured to the bag form an aseptic package.

What is claimed is: 1. A fitment for package holding a liquid therein, said fitment being arranged for selectively dispensing an amount of the liquid from the package, the package comprising a flexible bag in which the liquid is located and having a planar wall portion bounding the liquid, said fitment being a metering dispensing valve having a body, a fluid inlet check valve, a fluid outlet check valve, a bulb, a piercing element and an outlet, said body comprising a planar flange arranged for securement to the planar wall portion of the bag, said bulb being compressible and defining a collapsible reservoir into which the amount of the liquid from the bag can be transferred for dispensing, said inlet check valve being arranged to isolate said reservoir from a bag, said outlet check valve being arranged to isolate said reservoir from said outlet, said inlet check valve being coupled to said bulb and arranged to close in response to a compression of said bulb and open in response to the release of said bulb, said outlet check valve being coupled to said bulb and arranged to open in response to the compression of said bulb and close in response to the release of said bulb, said piercing element comprising a movable tubular member coupled to said bulb and having a passageway therethrough in fluid communication with said inlet check valve, said piercing element being arranged to be moved with respect to the planar wall portion of the bag and pierce through the planar portion of the wall of the bag in response to the compression of said bulb, whereupon the amount of the liquid in the bag is drawn into said reservoir through said inlet check valve, said bulb also being arranged to be compressed after the amount of the liquid is drawn into said reservoir to dispense the amount of the liquid through said outlet check valve to said outlet. 2. A package for holding and selectively dispensing an amount of a liquid therefrom, said package comprising a flexible bag and a fitment, said bag having a hollow interior in which the liquid is located and a planar wall portion bounding the liquid, said fitment being a metering dispensing valve having a body, a fluid inlet check valve, a fluid outlet check valve, a bulb, a piercing element and an outlet, said body comprising a planar flange arranged for securement to the planar wall portion of the bag, said bulb being compressible and defining a collapsible reservoir into which the amount of the liquid from said bag can transferred for dispensing, said inlet check valve being arranged to isolate said reservoir from said bag, said outlet check valve being arranged to isolate said reservoir from said outlet, said inlet check valve being coupled to said bulb and arranged to close in response to a compression of said bulb and open in response to a release of said bulb, said outlet check valve being coupled to said bulb and arranged to open in response to the compression of said bulb and close in response to the release of said bulb, said piercing element comprising a movable tubular member coupled to said bulb and having a passageway therethrough in fluid communication with said inlet check valve, said piercing element being arranged to be moved with respect to said planar wall portion of said bag and pierce through the planar portion of said wall of said bag in response to the compression of said bulb, whereupon the amount of the liquid in said bag is drawn into said reservoir through said inlet check valve, said bulb also being arranged to be compressed after the amount of the liquid is drawn into said reservoir to dispense the amount of the liquid through said outlet check valve to said outlet.
