Integrated time-indicating device during topical skin application

1 . An applicator comprising:

a body configured to house a fluid;

an application member in selective fluid communication with the body; and

a time-indicating device, wherein:

the time-indicating device comprises a capillary conduit having a fluid path,

the time-indicating device is configured such that fluid advancement along the fluid path provides at least a first observable signal signifying a first certain application period, and

the time-indicating device further comprises a fluid signaling component provided in an actuatable container, wherein the actuatable container is in direct or indirect selective fluid communication with the capillary conduit such that upon actuation of the actuatable container, the fluid signaling component is transferred to the capillary conduit.

2 . An applicator comprising:

a body configured to house a fluid;

an application member in selective fluid communication with the body; and

a time-indicating device, wherein:

the time-indicating device comprises a capillary component having a fluid path,

the capillary component comprises a sorbent in fluid communication with the application member,

the time-indicating device is configured such that fluid advancement along the fluid path provides at least a first observable signal,

the first observable signal signifies a first certain application period and comprises a color and/or color intensity change of the sorbent, and

the applicator is configured such that fluid advancement along the fluid path is visible to a user.

3 . The applicator according to claim 2 , wherein the sorbent comprises a signaling component provided at a position along the fluid path, and

wherein the first observable signal comprises a change in color, color intensity, translucency, volume, or position of the signaling component.

4 . The applicator according to claim 1 ,

wherein the applicator further comprises an actuator configured to actuate the applicator such that the body is provided in fluid communication with the application member, and

wherein the actuatable container is provided in a position relative to the actuator such that actuation of the applicator corresponds with actuation of the actuatable container.

5 . The applicator according to claim 1 , wherein the actuatable container is orientation-sensitive such that the actuatable container controllably releases the fluid signaling component therefrom when the applicator is provided in a first orientation.

6 . The applicator according to claim 1 , wherein the time-indicating device further comprises:

a fluid channel in selective fluid communication with the actuatable container, and

a fluid reservoir in fluid communication with the fluid channel and in fluid communication with the capillary conduit via a restrictive aperture.

7 . The applicator according to claim 1 , wherein the fluid is an antiseptic solution comprising at least one antiseptic agent and a solvent.

8 . The applicator according to claim 7 , wherein the first certain application period is a period of time required for the antiseptic solution to provide an acceptable antimicrobial effect, wherein the period of time is between about 30 seconds and 3 minutes.

9 . A method of applying a fluid to a surface, the method comprising:

providing an applicator comprising:

a body configured to house a fluid,

an application member in selective fluid communication with the body, and

a time-indicating device, wherein:

the time-indicating device comprises a capillary conduit having a fluid path,

the time-indicating device is configured such that fluid advancement along the fluid path provides at least a first observable signal signifying a first certain application period, and

the time-indicating device further comprises a fluid signaling component provided in an actuatable container, wherein the actuatable container is in direct or indirect selective fluid communication with the capillary conduit such that upon actuation of the actuatable container, the fluid signaling component is transferred to the capillary conduit;

actuating the applicator in order to apply the fluid to a surface; and

observing the time-indicating device for the first observable signal.

10 . A method of applying a fluid to a surface, the method comprising:

providing an applicator comprising:

a body configured to house a fluid,

an application member in selective fluid communication with the body, and

a time-indicating device, wherein:

the time-indicating device comprises a capillary component having a fluid path,

the capillary component comprises a sorbent in fluid communication with the application member,

the time-indicating device is configured such that fluid advancement along the fluid path provides at least a first observable signal,

the first observable signal signifies a first certain application period and comprises a color and/or color intensity change of the sorbent, and

fluid advancement along the fluid path is visible to a user;

actuating the applicator in order to apply the fluid to a surface; and

observing the time-indicating device for the first observable signal.

11 . The method according to claim 10 , wherein the sorbent comprises a signaling component provided at a position along the fluid path, and

wherein the first observable signal comprises a change in color and/or color intensity of the signaling component.

12 . The method according to claim 9 ,

wherein the applicator further comprises an actuator configured to actuate the applicator such that the body is provided in fluid communication with the application member, and

wherein the actuatable container is provided in a position relative to the actuator such that actuation of the applicator corresponds with actuation of the actuatable container.

13 . The method according to claim 9 , wherein the actuatable container is orientation-sensitive such that the actuatable container controllably releases the fluid signaling component therefrom when the applicator is provided in a first orientation.

14 . The method according to claim 9 , wherein the time-indicating device further comprises:

a fluid channel in selective fluid communication with the actuatable container, and

a fluid reservoir in fluid communication with the fluid channel and in fluid communication with the capillary conduit via a restrictive aperture.

15 . The method according to claim 9 , wherein the fluid is an antiseptic solution comprising at least one antiseptic agent and a solvent.

16 . The method according to claim 15 , wherein the first certain application period is a period of time required for the antiseptic solution to provide an acceptable antimicrobial effect, wherein the period of time is between about 30 seconds and 3 minutes.
