Abstract
A fluid applicator includes a fluid container having a collar mounted at an open top end. A base is mounted in the collar and is shaped to conform to the shape of a porous, spherical applicator member rotatably mounted in the collar, with a portion of the applicator member extending outward from the collar. An air intake conduit is centrally mounted in the base and draws air from the pores in the applicator member into the interior of the container to control the rate of fluid dispersion through fluid outlets formed in the base to the applicator member.
Claims15
A fluid applicator comprising:
- a hollow container for containing a fluid, the container having an open top end;
- a collar mounted on the open top end of the container, the collar having first and second ends;
- a base mounted within the collar and extending across the first end of the collar;
- an applicator member rotatably mounted in the collar and extending partially outward from the second end of the collar, the applicator member being formed of a porous material having open ended pores formed on the exterior surface thereof;
- fluid dispensing outlets formed in the base in fluid flow communication with the interior of the container to dispense fluid from the container to the applicator member;
- and
- a hollow air intake conduit having a first end formed in the base and disposed in fluid flow communication with the pores in the applicator member and a second end disposed within and in fluid flow communication with the interior of the container;
- the diameter of the fluid outlets having a predetermined size relative to the diameter of the air intake conduit which causes the amount of fluid dispensed through the fluid outlets to be substantially equal to the amount of air drawn into the air intake conduit.

A fluid applicator comprising:
- a hollow container for containing a fluid, the container having an open top end;
- a collar mounted on the open top end of the container, the collar having first and second ends;
- a hemispherically shaped base mounted within the collar and extending across the first end of the collar;
- a spherical applicator member rotatably mounted in the collar and extending partially outward from the second end of the collar, the applicator member being formed of a porous material having open ended pores formed on the exterior surface thereof;
- a magnetic member mounted on the base;
- the applicator member including a metallic material layer magnetically attractable to the magnetic member mounted in the base to hold the applicator member in the collar and allow rotation of the applicator member within the collar;
- fluid dispensing outlets formed in the base in fluid flow communication with the interior of the container to dispense fluid from the container to the applicator member;
- a hollow conduit having first and second ends, the first end being attached to the base and disposed in fluid communication through the base with the pores in the applicator member, the second end extending into the container;
- and
- a plurality of air intake grooves formed in the base facing the pores of the applicator member and communicating with the first end of the conduit for providing air flow in conjunction with the conduit into the interior of the container;
- the diameter of the fluid outlets having a predetermined size relative to the diameter of the air intake conduit which causes the amount of fluid dispensed through the fluid outlets to be substantially equal to the amount of air drawn into the air intake conduit.
