Abstract

A handheld topical applicator. The handheld topical applicator is preferably adapted to release a precise amount of liquid onto a surface and is preferably used for various applications such as marking a surface and/or providing a proper amount of dosage for medicinal applications. The handheld topical applicator may comprise a liquid delivery system for dispensing a precise amount of liquid onto various surfaces, a projecting/retracting mechanism, and an audible and/or tactile physical feedback mechanism. The projecting/retracting mechanism may controllably retract or protrude a nib into and out of the housing, and the audible/physical feedback mechanism may provide either a physical and/or audible click once a desired amount of liquid transfers onto the surface.

Claims

1. A handheld topical applicator, comprising:

a front housing;

a first nib;

a piston;

a biasing member; and

a reservoir;

wherein said front housing contains said reservoir;

wherein said reservoir is adapted to store a liquid;

wherein said first nib is coupled to a proximal end of said front housing and is adapted to be in fluid communication with said liquid stored in said reservoir;

wherein said piston is positioned at a distal end of said front housing;

wherein said biasing member is disposed inside said piston, such that said piston is adapted to bias towards said distal end of said front housing;

wherein said piston comprises;

a first cylinder, a second cylinder, one or more first tabs, and one or more second tabs;

wherein said one or more first tabs are disposed at an outer surface of said first cylinder;

wherein said one or more second tabs are disposed at an inner surface of said second cylinder; and

wherein said one or more first tabs and said one or more second tabs are adapted to produce an audible click after a user applies pressure to said first nib against a surface, such that said applied pressure causes said one or more first tabs to contact said one or more second tabs.

2. The handheld topical applicator of claim 1, further comprising:

a main housing;

wherein said main housing comprises a central opening;

wherein said main housing substantially encloses said front housing, such that, at least a portion of said first nib protrudes through said central opening of said main housing and controllably retracts through said central opening of said main housing upon said applied pressure of said first nib onto a surface;

wherein said front housing comprises a shoulder located at an exterior of said front housing;

wherein said main housing comprises an inner flange located inside an interior of said main housing; and

wherein said shoulder is adapted to restrict said projection of said at least said portion of said first nib through said central opening of said main housing when said shoulder of said front housing contacts said inner flange of said main housing.

3. The handheld topical applicator of claim 2, wherein said one or more first tabs and one or more second tabs produce a tactile response upon receiving said applied pressure to said first nib.

4. The handheld topical applicator of claim 1, wherein said first nib is one of a plurality of nibs;

and

wherein said first nib is adapted to be replaced with one or more different nibs of said plurality of nibs.

5. The handheld topical applicator of claim 4, wherein said plurality of nibs have different porosity densities, such that said handheld topical applicator is adjustable for one or more different applications.

6. The handheld topical applicator of claim 4, wherein said one or more of said plurality of nibs are constructed of an anti-microbial material.

7. The handheld topical applicator of claim 1, wherein said liquid stored in said reservoir is limited to an amount for a single use application, such that said handheld topical applicator is a single use device.

8. The handheld topical applicator of claim 1, wherein said main housing comprises a window indicator positioned outside said reservoir to show an amount of said liquid stored in said reservoir.

9. The handheld topical applicator of claim 8, wherein said front housing is constructed of a transparent material.

10. The handheld topical applicator of claim 1, wherein said first nib is adapted to change color based on an amount of said liquid stored in said reservoir.

11. The handheld topical applicator of claim 1, wherein said first nib is adapted to release a predetermined amount of liquid when said first nib is applied against a surface based on a flow rate;

wherein said flow rate is based on a material density of said reservoir and a porosity of said first nib.

12. A handheld topical applicator, comprising:

a front housing;

a first nib;

a piston;

a biasing member; and

a reservoir;

wherein said front housing contains said reservoir;

wherein said reservoir is adapted to store a liquid;

wherein said first nib is coupled to a proximal end of said front housing and is adapted to be in fluid communication with said liquid stored in said reservoir;

wherein said piston is positioned at a distal end of said front housing;

wherein said biasing member is disposed within said piston, such that said piston is adapted to bias towards said distal end of said front housing;

wherein said piston comprises;

a first cylinder, a second cylinder, one or more first tabs, and one or more second tabs;

wherein said one or more first tabs are disposed at an outer surface of said first cylinder;

wherein said one or more second tabs are disposed at an inner surface of said second cylinder; and

wherein said one or more first tabs and said one or more second tabs are adapted to produce an audible click after a user applies a pressure to said first nib against a surface for a predetermined amount of time, such that said applied pressure of said first nib against said surface causes said one or more first tabs to contact said one or more second tabs.

13. The handheld topical applicator of claim 12, further comprising:

a main housing;

wherein said main housing comprises a central opening;

wherein said main housing substantially encloses said front housing, such that, at least a portion of said first nib protrudes through said central opening of said main housing and controllably retracts through said central opening of said main housing upon compression of said first nib onto a surface;

wherein said front housing comprises a shoulder located at an exterior of said front housing;

wherein said main housing comprises an inner flange located inside an interior of said main housing; and

wherein said shoulder is adapted to restrict said projection of said portion of said first first nib through said central opening of said main housing when said shoulder of said front housing contacts said inner flange of said main housing.

14. The handheld topical applicator of claim 13, wherein said one or more first tabs and one or more second tabs produce a tactile response upon receiving said applied pressure to said first nib.

15. The handheld topical applicator of claim 14, wherein said first nib is one of a plurality of nibs;

and

wherein said first nib is adapted to be replaced with one or more different nibs of said plurality of nibs.

16. The handheld topical applicator of claim 15, wherein said one or more different nibs have different porosity densities, such that said handheld topical applicator is used for one or more different applications.

17. The handheld topical applicator of claim 16, wherein said main housing comprises a window indicator positioned outside said reservoir;

wherein said window indicator shows an amount of said liquid stored in said reservoir.

18. The handheld topical applicator of claim 17, wherein said front housing is constructed of a transparent material.

19. The handheld topical applicator of claim 18, wherein said first nib is adapted to change color based on an amount of said liquid stored in said reservoir.

20. The handheld topical applicator of claim 12, wherein said first nib is adapted to release a predetermined amount of liquid when said first nib is applied against a surface based on a flow rate;

and

wherein said flow rate is based on a material density of said reservoir and a porosity of said first nib.
