Abstract
Drip tape for below or above ground irrigation includes a sheet of material formed into a tube by overlapping opposite side edges of the sheet and bonding the side edges along a longitudinal seam thereby forming a primary flow path. A strip of transparent material is bonded to an interior surface of the sheet prior to seaming, at a location remote from the longitudinal seam so as to define, in combination with the tape wall, a plurality of secondary flow paths within the primary flow path. Each secondary flow path includes an inlet region, a turbulence inducing region and an outlet region; the inlet region including a plurality of inlets in the second strip connecting the primary flow path to the secondary flow path upstream of the turbulence inducing region; the outlet region including an outlet in the tube connecting the secondary flow path to atmosphere downstream of the turbulence inducing region.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
