Abstract: A package for enabling the dispensing (metering of) a flowable material by use of dispensing apparatus is disclosed. The package is a flexible bag or pouch having an internal cavity in which the flowable material is disposed and a fitment through which the flowable material is metered. The fitment is arranged to receive a probe of the dispensing apparatus and includes a first valve to prevent the flowable material from exiting through the fitment until the fitment is connected to the probe. The probe includes a second valve which opens when the probe is connected to the fitment and which closes when the probe is disconnected from the fitment. The disconnection of the probe from the fitment causes the first valve to close. The fitment also includes an anti-blocking member which prevents the walls of the package from collapsing to block the fitment when the flowable material is metered out.
