Agricultural drip tape

Drip tape for below or above ground irrigation comprising:

• a sheet strip of material formed into a tube by overlapping opposite side edges of said strip and bonding said side edges along a longitudinal seam thereby forming a primary flow path;
• a strip of substantially transparent material bonded to an interior surface of said tube at a location remote from said longitudinal seam;
• said strip of material and said sheet of material defining a plurality of secondary flow paths within said primary flow path having a radially inner wall defined in part by a reduced thickness portion of said strip and a radially outer wall defined by said tube, each secondary flow path including an inlet region, a turbulence inducing region and an outlet region;
• said inlet region including a plurality of inlets on opposite sides of said strip connecting said primary flow path to said secondary flow path upstream of said turbulence inducing region;
• said outlet region including an outlet in said tube connecting said secondary flow path to atmosphere downstream of said turbulence inducing region.

Agricultural drip irrigation tape comprising:

• a tubular member defining a primary flow path;
• a substantially transparent strip member secured to a surface of said tubular member and defining at least one secondary flow path;
• at least one inlet from said primary flow path to said secondary flow path;
• and
• at least one outlet from said secondary flow path to atmosphere.

Agricultural drip tape comprising:

• a tubular member defining a primary flow path;
• a substantially transparent strip member secured to a surface of said tubular member and defining, with said tubular member, a secondary flow path having a flow channel therein;
• said secondary flow path including axially aligned inlet, turbulence inducing and outlet regions, wherein said inlet region comprises a plurality of inlet openings formed in opposite sides of said strip, perpendicular to said flow channel, with inlets on one side longitudinally offset from inlets on the other side;
• and
• at least one outlet in said tubular member connecting said secondary flow path to atmosphere.

Drip tape for below or above ground irrigation comprising:

• an elongated flexible tubular member forming a primary flow path;
• an elongated strip secured to an interior surface of said tubular member and formed to include at least one secondary flow path, wherein said secondary flow path is at least partially formed by substantially transparent material;
• a plurality of inlets in said strip connecting said primary flow path to said secondary flow path;
• and
• an outlet in said tubular member connecting said secondary flow path to atmosphere.

Drip tape for below or above ground irrigation comprising:

• an elongated flexible tubular member forming a primary flow path;
• an elongated strip secured to an interior surface of said tubular member and formed to include at least one secondary flow path, said secondary flow path including discrete, axially aligned inlet, turbulence inducing, and outlet regions, with a secondary flow channel extending through said regions, and wherein a pair of elongated grooves are formed in said strip, on either side of said turbulence inducing region, in order to enhance uniform distribution of material during formation of said elongated strip;
• a plurality of inlets in said strip connecting said primary flow path to said secondary flow path;
• and
• an outlet in said tubular member connecting said secondary flow path to atmosphere.
