Abstract:
1. An apparatus comprising: a fluid reservoir; a compressible metering chamber comprising a first end coupled to the fluid reservoir and a second end; a valve coupled to the second end of the metering chamber, the valve having a deformable base member and a deformable skirt member positioned around the deformable base member; and a nozzle coupled to the valve, the nozzle having a reservoir within which the valve is positioned, wherein the reservoir defines an annular chamber having an inner side and an outer side which are substantially parallel and face one another, wherein a distance between the inner side and the outer side define a gap, wherein a portion of the deformable skirt member lies in the gap, wherein a thickness of the gap is greater than a thickness of the portion of the deformable skirt member such that the deformable skirt member forms a seal with the outer side of the annular chamber when the deformable base member is in the open position and a seal with the inner side of the annular chamber when the deformable base member is in a closed position.
