An anti-clog cap for a glue bottle, comprising: a body that comprises: a mounting section comprising a first mounting end adapted for mounting the body to a glue bottle, and a second mounting end; a dispensing section extending distally from the second mounting end and comprising an inlet end adjacent to the second mounting end of the mounting section, an outlet end opposite the inlet end, and a central lumen extending between the inlet end and the outlet end; a tip section extending distally from the outlet end of the dispensing section, the tip section comprising a support rib protruding distally from the outlet end of the dispensing section, and a tip plug protruding distally from the support rib; and a nozzle that comprises a mating end adapted for attachment to the body, and a distal end comprising a tip orifice, the tip orifice being in axial alignment with the tip plug of the body, wherein the tip section of the body is dimensioned to facilitate the free flow of glue through the cap, wherein the nozzle is rotatable between a closed position and an open position, such that when the nozzle is in the closed position, the tip plug extends into the tip orifice, substantially preventing the flow of glue through the tip orifice, and when the nozzle is in the open position, the tip plug is positioned outside of and proximal to the tip orifice, to facilitate the free flow of glue through the tip orifice, and characterized in that the support rib is an arcuate rib extending distally from a first position on the outlet end of the dispensing section, passing through a longitudinal centerline of the central lumen, and terminating at a second position on the outlet end of the dispensing section, and wherein the arcuate rib is dimensioned to follow the interior profile of the nozzle along at least one plane, maximizing the area bounded by the support rib and the outlet end of the dispensing section. a body that comprises: a mounting section comprising a first mounting end adapted for mounting the body to a glue bottle, and a second mounting end; a dispensing section extending distally from the second mounting end and comprising an inlet end adjacent to the second mounting end of the mounting section, an outlet end opposite the inlet end, and a central lumen extending between the inlet end and the outlet end; a tip section extending distally from the outlet end of the dispensing section, the tip section comprising a support rib protruding distally from the outlet end of the dispensing section, and a tip plug protruding distally from the support rib; and a mounting section comprising a first mounting end adapted for mounting the body to a glue bottle, and a second mounting end; a dispensing section extending distally from the second mounting end and comprising an inlet end adjacent to the second mounting end of the mounting section, an outlet end opposite the inlet end, and a central lumen extending between the inlet end and the outlet end; a tip section extending distally from the outlet end of the dispensing section, the tip section comprising a support rib protruding distally from the outlet end of the dispensing section, and a tip plug protruding distally from the support rib; and a nozzle that comprises a mating end adapted for attachment to the body, and a distal end comprising a tip orifice, the tip orifice being in axial alignment with the tip plug of the body, wherein the tip section of the body is dimensioned to facilitate the free flow of glue through the cap, wherein the nozzle is rotatable between a closed position and an open position, such that when the nozzle is in the closed position, the tip plug extends into the tip orifice, substantially preventing the flow of glue through the tip orifice, and when the nozzle is in the open position, the tip plug is positioned outside of and proximal to the tip orifice, to facilitate the free flow of glue through the tip orifice, and
