1. A dispenser for fluid material, comprising:
- (a) a body defining an interior reservoir for holding a quantity of the fluid material, said reservoir having an opening;
(b) an applicator for conveying fluid material from said reservoir through said opening to a locality, external to said body, at which it is desired to deliver and apply the fluid material, said applicator being movable from said reservoir forwardly through said opening to an extended location outside said reservoir and rearwardly through said opening to a retracted location within said reservoir;
(c) a wiper disposed in said reservoir and having a wiping portion movable into and out of a position for engaging said applicator to wipe excess fluid material therefrom; and
(d) structure, including a movable member, disposed within said reservoir for causing said wiping portion to move into and out of said position, said member being actuated by arrival of said applicator at said retracted and extended locations, respectively, such that said wiping portion is in said position during forward movement of said applicator from said retracted location and is out of said position during rearward movement of said applicator from said extended location.

19. A dispenser for fluid material comprising:
-
(a) a body defining an interior reservoir for holding a quantity of the fluid material, said reservoir having an opening; (b) an applicator for conveying fluid material from said reservoir through said opening to a locality, external to said body, at which it is desired to deliver and apply the fluid material, said applicator having an axis and a free tip and being retractably carried by said body for movement along said axis from said reservoir outwardly through said opening to an extended location external to said body, and inwardly through said opening to a retracted location within said reservoir, the applicator tip being disposed adjacent said opening when the applicator is in said retracted position; and (c) a wiper disposed in said reservoir for engaging said applicator to wipe excess fluid material therefrom as said applicator moves outwardly through said opening, said wiper being in contact with said applicator adjacent said tip when said applicator is in said retracted position to maintain said tip clean and free of said fluid material.

20. A dispenser for fluid material comprising:
-
(a) body defining an elongated, axially rectilinear interior reservoir for holding a quantity of the fluid material, said reservoir having a forward end with an opening therein and a rearward wall, and having a substantially uniform cross-section for at least a substantial portion of its length forwardly of said rearward wall; (b) an applicator for conveying fluid material from said reservoir through said opening to a locality, external to said body, at which it is desired to deliver and apply the fluid material, said applicator having an axis and being retractably carried by said body for movement along said axis from said reservoir forwardly through said opening to an extended location external to said body, and rearwardly through said opening to a retracted location within said reservoir, said applicator including a rod extending along said axis through said reservoir from said rearward end thereof; and (c) means for controlling the position of fluid material within the reservoir, said means including a movable wall element through which said rod extends, said wall element being disposed within said reservoir so as to be positioned between said rearward wall and said fluid material in the reservoir and being dimensioned to substantially occlude said reservoir transversely, and a spring under compression between said rearward wall and said wall element for urging said wall element away from said rearward wall with sufficient force to control the reservoir volume available for occupation by the fluid material in correspondence with the amount of fluid material present in the reservoir, but insufficient to expel fluid material through the opening.
