The invention claimed is: 1. A fluid dispenser assembly, the assembly comprising: a container body for storing a liquid material, the body having a reservoir and a dispensing opening on an upper end with an axis; a cup-shaped insert stationarily installed within the container body at the dispensing opening, the insert having an interior and a passage leading to the interior for communication with the reservoir of the container body; a dispenser in the dispensing opening and having an inner portion that extends into the interior of the insert, the dispenser being axially moveable with respect to the container body and the insert between an open position opening the passage in the insert and a closed position wherein the inner portion of the dispenser blocks the passage in the insert, the dispenser having an aperture formed therein for allowing liquid material in the container to flow from the passage in the insert into the dispenser while in the open position; a cap releasably secured to the container body, the cap causing the dispenser to move to the closed position when closing the cap on the container body; an applicator mounted to and protruding from the dispenser for receiving liquid material flowing through the aperture in the dispenser and for applying the liquid material to an object, the applicator being enclosed by the cap while the cap is closed on the container; a coiled spring in an annular space between the insert and the dispenser that urges the dispenser toward the open position, the spring being located within the interior of the insert and isolated from a flow path for the liquid material while the dispenser is in the open position; and the insert and the dispenser having mating wall surfaces that slidingly contact each other and are located below the spring to prevent entry of the liquid material into the annular space and into contact with the spring while the dispenser is in the open position. 2. A fluid dispenser assembly, the assembly comprising: a container body having a reservoir for storing a liquid material, the body having a dispensing opening with an axis; a dispenser; an insert mounted within the container body at the dispensing opening of the container, the insert having a hollow interior and a passage in communication with the reservoir of the container, the dispenser having a lower portion with a port that is within the hollow interior of the insert, and within the dispensing opening of the container, the dispenser being carried by the insert for relative axial movement between an open position wherein the passage in the insert and the port are open and a closed position wherein a bottom portion of the dispenser contacts the insert to block communication between the passage in the insert and the port in the dispenser; a coiled spring disposed between the insert and the dispenser above the bottom portion of the dispenser to bias the dispenser toward the open position, the spring being isolated from the flow path to avoid contact with the liquid material; a cap matingly engagable with the container body, the cap causing the dispenser to move to the closed position when closing the cap on the container body; an applicator mounted to and protruding from the dispenser for receiving liquid material flowing through the passage in the insert and the port in the dispenser while the dispenser is in the open position, the applicator being enclosed by the cap while the cap is closed on the container; wherein the dispenser has a lower portion that is in sliding engagement with a mating portion in the interior of the insert; the spring encircles the dispenser above the mating portion of the insert; and the sliding engagement of the lower portion of the dispenser with the mating portion of the insert isolates the flow of the liquid material into contact with any portion of the spring while the dispenser is in the open position. 3. The assembly of claim 2, wherein the cap has a set of internal threads that engage a set of external threads on the container. 4. A fluid dispenser assembly, the assembly comprising: a container body having a reservoir for storing a liquid material, the body having a tubular upper portion with an exterior having a set of threads; an insert member mounted stationarily within the upper portion of the container body, the insert member having a cylindrical side wall, an open upper end and a bottom, defining a receptacle, the insert member having a passage communicating the receptacle with the reservoir of the container body; a dispenser having a lower portion with an exterior mating portion that fits slidingly within an interior mating portion of the receptacle of the insert member and located within the upper portion of the container body, the lower portion of the dispenser having a port, the dispenser being moveable between upper and lower positions relative to the receptacle for opening and closing the passage in the insert member, the dispenser having a bottom portion that contacts the insert to block communication between the passage in the insert and the port in the dispenser when the dispenser is in the closed position; an applicator mounted to and protruding from the dispenser, the dispenser having an opening for communicating to the applicator liquid material flowing from the passage in the insert member while the dispenser is in the upper position; the dispenser having a downward-facing shoulder located above an upward facing shoulder of the receptacle, defining an annular space between the dispenser and the receptacle, the annular space being above where the mating portions of the dispenser and the insert member engage each other to inhibit flow of the liquid material into the annular space; a coiled spring within the annular space above the bottom portion of the dispenser and having ends in engagement with the downward facing shoulder and upward facing shoulder to bias the dispenser toward the upper position, the spring being above where the mating portions of the dispenser and the insert slidingly engage each other, so as to be isolated from the liquid material while the dispenser is in the upper opened position; and a cap enclosing the applicator and the dispenser, the cap having a set of interior threads that engage the threads on the container body, the cap causing the dispenser to move to the lower position when closing the cap on the container body.
