Patent ID: 8887749

Claim:
An apparatus comprising: a flexible tube having a first opening at a first end, an opposing second opening at a second end, and a body portion between the first end and the second end; wherein the body portion has an inner cavity; wherein the body portion of the flexible tube has a plurality of further openings leading out from the inner cavity; wherein each of the plurality of further openings is smaller than the first opening and the second opening; a first connector connected at the second end of the flexible tube, wherein the first connector is configured to be connected to a water source; a first outer member having a first opening at a first end, an opposing second opening at a second end, and a body portion between the first end of the first outer member and the second end of the first outer member; wherein the body portion of the first outer member is non porous; wherein the first outer member substantially surrounds a portion of the flexible tube so that the first outer member blocks a first set of the plurality of further openings to inhibit liquid flow from the first set of the plurality of further openings; wherein the first outer member is configured so that it can be stretched from a first state to a second state; wherein in the first state the first outer member is configured to block the first set of the plurality of further openings to inhibit liquid flow from the first set of the plurality of further openings; wherein in the second state the first outer member is configured to block a second set of the plurality of further openings to inhibit liquid flow from the second set of the plurality of further openings; wherein the second set includes the first set of the plurality of further openings and an additional one or more openings of the plurality of further openings; wherein the first outer member has a length in the first state; wherein the first outer member has a length in the second state; wherein the flexible tube has a length which is greater than twice the length of the first outer member in the first state; wherein the length of the first outer member in the second state is between about twice as long as the length of the first outer member in the first state and the length of the flexible tube; and wherein the first outer member is made of a material so that the first outer member can be rolled out in order to stretch the first outer member from the first state to the second state.
