Abstract: A device for controlling fluid flow from a subsurface fluid reservoir into a production tubing siring includes a tubular member defining a central bore. At least one nozzle extends through a side wall of the tubular member. A popper is moveable between an open position where fluids can flow into the central bore through the nozzle, and a closed position where the nozzle is fluidly sealed. A circumferential external bead profile is located on the stem and a circumferential groove is located in the nozzle for mating with the head profile of the stem and maintaining the popper in a closed position. The device can also have a shear member disposed between the stem of the popper and an inner surface of the nozzle for supporting the popper in an open position before the popper is moved to the closed position.
