A pump dispenser package for a fluent material comprising:
- a body having a hollow interior for receiving the fluent material the hollow interior of said body being in communication with atmosphere;
- a hollow pump chamber having first and second openings and interior walls, said pump chamber being mounted on one end of said body;
- a reciprocating hollow pump wherein one end thereof is inserted into the interior of said pump chamber through the first opening, said pump slideably and sealingly engaging the interior walls of said pump chamber during reciprocation of said pump;
- a nozzle having an outlet, said nozzle being positioned at the opposite end of said pump and in communication with the interior of said pump chamber via said pump;
- a hollow tube connected to one end of said pump chamber for providing a passageway for the fluent material in said body into said pump chamber via the second opening;
- means for selectively closing the second opening of said pump chamber;
- a hollow cover mounted on said body adjacent said nozzle for rotational and reciprocal motion;
