Applicator for transporting, dispensing and applying material
A cosmetic applicator for transporting and applying cosmetic material, including a rotating applicator tip which, when rotated, dispenses cosmetic material onto the tip such that the user does not need to periodically dip the applicator tip into a reservoir of cosmetic material.
1. A device for applying material to a surface comprising:
a tip having an interior space, an outer surface, and a passage between the interior space and the outer surface which allows the material to move from the interior space onto the outer surface;
a receptacle having an interior space for storing the material; and
a connection between the tip and the receptacle which allows the tip to rotate with respect to the receptacle and which allows the material from the interior space of the receptacle to move into the interior space of the tip, wherein the connection comprises:
a first set of teeth and a second set of teeth at one end of the tip;
a set of teeth at one end of the receptacle engagable by the first set of teeth; and
a set of teeth on a moveable platform positioned within the receptacle engagable by the second set of teeth.
2. A device as in claim 1 wherein:
the first set of teeth of the tip form an outer circle;
the second set of teeth of the tip form an inner circle within the outer circle;
the set of teeth at one end of the receptacle form a circle; and
the moveable platform forms a wheel having the set of teeth formed in a circle.
3. A device as in claim 2 wherein the device further comprises:
an elongated portion of the wheel extending into the receptacle, the elongated portion having threads;
a plunger nut positioned in the receptacle having threads for engaging the threads of the elongated portion and an alignment slot; and
the receptacle having at least one alignment rib for engaging the alignment slot of the plunger nut.
4. A device as in claim 1 wherein:
each tooth of the first set of teeth has a slanted side and a substantially vertical side; and
each tooth of the second set of teeth has a slanted side and a substantially vertical side,
such that each side of each tooth of the first set of teeth faces in the opposite direction of the corresponding side of each tooth of the second set of teeth.
5. A device as in claim 4 wherein:
each tooth of the set of teeth of the receptacle has a slanted side and a substantially vertical side; and
each tooth of the set of teeth of the moveable platform has a slanted side and a substantially vertical side,
such that each side of each tooth of the set of teeth of the receptacle faces in the opposite direction of the corresponding side of each tooth of the first set of teeth and each side of each tooth of the set of teeth of the moveable platform faces in the opposite direction of the corresponding side of each tooth of the second set of teeth.
6. A method of causing material to be dispensed from a tip of an applicator device according to claim 1 having a receptacle for the material comprising the steps of:
moving the tip of the applicator in a first direction with respect to the receptacle to dispense the material; and
moving the tip of the applicator in a second direction with respect to the receptacle to dispense the material.
7. The method of claim 6 in which the first moving step comprises the steps of:
engaging a second set of teeth at one end of the tip with a set of teeth on a moveable platform, the moveable platform positioned at least partially within the receptacle,
such that the engaging causes the moveable platform to move with respect to the receptacle.
8. The method of claim 7 in which the second moving step comprises the steps of:
engaging a first set of teeth at one end of the tip with a set of teeth on the receptacle,
such that the engaging causes the receptacle to move with respect to the moveable platform.
9. The method of claim 7 wherein:
the moveable platform comprises a wheel having a portion having threads which extend away from the tip and into the receptacle; and
a plunger nut positioned within the receptacle has complementary threads to the threads of the wheel, such that rotation of the threads causes the plunger nut to move toward the tip and thereby cause material in the receptacle to move toward the tip.
10. The method of claim 9 wherein:
the plunger nut has an alignment slot which engages an alignment rib in the receptacle, such that rotation of the receptacle causes the plunger nut to move toward the tip and thereby cause material in the receptacle to move toward the tip.
