Abstract:
A dispenser for masking fluid or other viscous fluid, said dispenser comprising, in combination:a viscous fluid reservoir; a spout having a spout proximal end and a spout distal end connected to said reservoir at said spout proximal end; a hollow nib attached to the spout at the spout distal end and projecting outwardly from said spout distal end, said hollow nib for receiving viscous fluid supplied to said spout from said reservoir, and said hollow nib having an open distal fend spaced from said spout for dispensing viscous fluid received by said hollow nib from said spout; an end cap assembly releasably attached to said spout, said end cap assembly including a hollow member and an end cap, said hollow member having an open hollow member proximal end for releasable engagement with said spout and a hollow member distal end, said end cap being releasably connected to said hollow member distal end, said hollow member when releasably engaging said spout accommodating therein a portion of said spout and said nib, and said end cap assembly further including a prong attached to said hollow member at said hollow member distal end and extending within said hollow member in the direction of said hollow member proximal end, said prong being removably positioned in said hollow nib to seal said hollow nib and prevent egress of viscous fluid from said hollow nib and operable to contribute to cleaning of said hollow nib when inserted therein, said prong having a prong distal end, and said prong projecting from the hollow member proximal end with said prong distal end spaced from and disposed outwardly of the hollow member proximal end; and an O-ring connected to and surrounding said spout between the spout proximal end and the spout distal end engaged by said hollow member proximal end and forming a seal between said spout and said hollow member when said hollow member releasably engages said spout.
