ABSTRACT:
A drip retainer for preventing residual fluid in a spout from dripping includes a tubular resilient member which is flattened at one end so that opposite walls are biased together. An opposite end of the tubular member is connected in a liquid-tight manner to the spout. A cylindrical clamp is mounted on the flattened portion of the tubular member. A hollow area inside the cylindrical clamp is filled with resilient biasing material. The biasing material, on either side of the flattened portion, urges the tubular member to a flat closed position. When liquid is pumped through the spout under pressure, the liquid urges the flattened portion of the tubular member to an open position. When pressure subsides, the biasing material urges the flattened portion back to its closed position, so that residual fluid clinging to inside walls of the spout cannot escape.
