Abstract
A drip irrigation pipe includes a drip emitter and a flap that is formed in the pipe wall by first and second grooves. The first groove is longer than the second groove and the flap remains connected to the pipe wall at two bridges. A pivot region of the flap extends between the two bridges and the flap is adapted to twist about the pivot region as liquid exits the pipe at the flap.
Claims15
A drip irrigation pipe comprising a drip emitter and a flap,
- the drip emitter being located along the pipe wall adjacent the flap so that liquid passing through the emitter is able to exit the pipe at the flap,
- the flap being defined by first and second slits formed through the pipe wall and the flap remaining connected to the pipe wall at two bridges, a first one of the bridges being located between a beginning of the first slit and a first location along the second slit proximal to the beginning, a second one of the bridges being located between an end of the first slit and a second location along the second slit proximal to the end, and a pivot of the flap extending between the bridges, wherein the first and second slits do not merge with one another and;
- an operative part of the flap bound between the first slit and the pivot is sized such that liquid exiting the pipe at the flap bears against the operative part to twist the flap in a positive direction about the pivot such that any part of the flap that twists does so in the positive direction.
A drip irrigation pipe comprising a drip emitter and a flap being defined by first and second slits formed through the pipe wall,
- the drip emitter being located along the pipe wall adjacent the flap so that liquid passing through the emitter is able to exit the pipe at the flap,
- the first and second slits each extending between a beginning and an end and the flap remaining connected to the pipe wall at two bridges, a first one of the bridges being located between the beginnings of the slits and a second one of the bridges being located between the ends of the slits such that the first and second slits do not merge with one another,
- a pivot of the flap being defined as extending between the two bridges, wherein
- a first part of the flap bound by the first slit and the pivot is larger than a second part of the flap bound by the second slit and the pivot.
