Patent attributes
A package for dispensing a fluent material contained in the package. The package can include a first polymeric sidewall having a first perimeter and a second polymeric sidewall having a second perimeter, the first and second polymeric sidewalls being joined at least along a portion of the first and second perimeters to define a flexible pouch having an interior compartment for a contained fluent material in an equilibrium pressure state. An opening permits fluid communication through the first opening upon the contained fluent material being in a positive pressure state greater than the equilibrium pressure state. The opening can have a magnetic valve, the magnetic valve having a first magnetic region and an opposing second magnetic region. The first magnetic region and second magnetic region can be in a separable magnetically contacting state to alternately permit and prevent fluid communication of the fluent material.
