A drip emitter sized for insertion into a liquid supply tube and positioned adjacent to a dripping aperture in the tube, the drip emitter comprising:
- an emitter body having a convex side configured to internally and adjacently fit the tube and an opposite flat side comprising a regulator, wherein the convex side comprises an outlet chamber configured to be fluidically connected to the dripping aperture;
- a membrane covering at least the regulator;
- a cover provided with a liquid intake having a filter, wherein the cover is configured to envelop the emitter body except for most of said convex side;
- and
- a first plurality of long studs and a second plurality of short studs configured on the flat side, and a first plurality of long sockets and a second plurality of short sockets configured on the cover, wherein each of the first plurality of long sockets is configured for receiving therein a corresponding one the first plurality of long studs, and each of the second plurality of short sockets is configured for receiving therein one of the second plurality of short studs, and wherein each of the plurality of long sockets at least partially protrudes from an outer surface of the cover and protrudes further from the outer surface than the plurality of short sockets;
- wherein the long studs, short studs, long sockets, and short sockets are configured to join said flat side and an inner surface of the cover that is adjacent to the flat side so as to join the cover to the emitter body wherein the membrane is retained therebetween.

In a drip emitter sized for insertion into a liquid supply tube and positioned adjacent to a dripping aperture in the tube, the drip emitter comprising:
- an emitter body having a convex side comprising a primary labyrinth and an outlet chamber configured to be fluidically connected to the dripping aperture and an opposite flat side comprising a regulating labyrinth, wherein the convex side is configured to internally and adjacently fit the tube;
- a membrane covering at least the regulating labyrinth;
- and
- a cover provided with a liquid intake having a filter, wherein the cover is configured to envelop the emitter body except for most of said convex side wherein an edge of the cover internally and adjacently fits the tube;
- an improvement comprising:
- a first plurality of long studs and a second plurality of short studs configured on the flat side, and a first plurality of long sockets and a second plurality of short sockets configured on the cover, wherein each of the first plurality of long sockets is configured for receiving therein a corresponding one of the first plurality of long studs, and each of the second plurality of short sockets is configured for receiving therein one of the second plurality of short studs, and wherein each of the plurality of long sockets at least partially protrudes from an outer surface of the cover and protrudes further from the outer surface than the plurality of short sockets;
- wherein the long studs, short studs, long sockets, and short sockets are configured to join the flat side of the body to an inner surface of the cover that is adjacent to the flat side, wherein the membrane is retained therebetween;
- and
- wherein at least one of the plurality of long sockets comprises an indicator provided on the cover for indicating a position of the outlet chamber.
11-12. (canceled)
In a drip emitter sized for insertion into a liquid supply tube and positioned adjacent to a dripping aperture in the tube, the drip emitter comprising:
- an emitter body having a convex side comprising an outlet chamber configured to be fluidically connected to the dripping aperture and an opposite flat side comprising a labyrinth and a regulating pool having a hole and a slot, wherein the convex side is configured to internally and adjacently fit the tube;
- a membrane covering the regulating pool and at least a part of the labyrinth;
- and
- a cover having a liquid intake and a filter, wherein the cover is configured to envelop the emitter body except for said convex side wherein an edge of the cover internally and adjacently fits the tube;
- an improvement comprising:
- a first plurality of long studs and a second plurality of short studs configured on the flat side, and a first plurality of long sockets and a second plurality of short sockets configured on the cover, wherein each of the first plurality of long sockets is configured for receiving therein a corresponding one of the first plurality of long studs, and each of the second plurality of short sockets is configured for receiving therein one of the second plurality of short studs, and wherein each of the plurality of long sockets at least partially protrudes from an outer surface of the cover and protrudes further from the outer surface than the plurality of short sockets;
- wherein the plurality of long studs, short studs, long sockets, and short sockets are configured to join the flat side of the body to an inner surface of the cover that is adjacent to the flat side, wherein the membrane is retained therebetween.
(canceled)
A drip emitter sized for insertion into a liquid supply tube and positioned adjacent to a dripping aperture in the tube, the drip emitter comprising:
- an emitter body having a convex side provided with a labyrinth and configured to internally and adjacently fit the tube and an opposite flat side comprising a regulating labyrinth, wherein the convex side comprises an outlet chamber configured to be fluidically connected to the dripping aperture;
- a membrane covering at least the regulating labyrinth;
- a substantially flat cover provided with a liquid intake having a filter;
- and
- a projecting rim configured to allow ultrasonic welding between the cover and the emitter body wherein the projecting rim encircles at least the regulating labyrinth,
- wherein the cover and the emitter body are connected to one another through the ultrasonic welding of the projecting rim while the membrane is retained therebetween, and
- wherein the projecting rim can be provided on the cover or on the body.
