Abstract (en)
[origin: US4572360A] The herb package described is made of a synthetic foil having therein plural perforations for allowing fluids, but not solids, to exit and/or enter the package. The perforations are formed by needling, created inward or outward deformation of the foil at each puncture point, whereby each perforation tends to act as a one-way valve in a direction corresponding to the direction of needle penetration. Some of the perforations are formed by inward needling, some by outward needling, so that pressure cycling pumps water through the package contents.
