Abstract: Glue bottle anti-clog caps are provided. The anti-clog cap has a body with a mounting section for attaching the body to a glue bottle. The body of the anti-clog cap has a dispensing section that includes a central lumen extending from the second mounting end. The body of the anti-clog cap also has a tip section with a support rib protruding from an outlet of the dispensing section. The tip has a tip plug protruding from the support rib. The anti-clog cap has a nozzle that mates to the body and a tip orifice aligned with the tip plug of the body. The tip section is configured to allow the free flow of glue through the cap. The nozzle can rotate between an open and closed position. In the closed position the tip plug can extend into the tip orifice thereby preventing the flow of glue.
