Abstract

A scrub brush for cleaning arms, hands, and fingernails includes a reservoir for applying an antiseptic or cleaning composition and first and second groups of bristles having different relative flexibilities. The reservoir can be an absorbent open-foam material capable of absorbing and holding a liquid cleaning composition. The first bristles are designed to gently cleanse skin surfaces without scratching, gouging, scraping or otherwise damaging skin. The second bristles are more rigid than the first bristles to more aggressively scrub dirt, microbes or other foreign debris from gaps underneath fingernails. A finger alignment guide adjacent to the stiffer bristles maintains proper alignment between fingernails and the stiffer bristles so that the bristles enter gaps underneath the fingernails when the fingers are moved in a back and forth motion.

Claims

1. A scrub brush for cleaning arms, hands, and fingernails, comprising:

a reservoir body comprising an absorbent material capable of absorbing and holding therein a cleaning composition;

a plurality of arm and hand scrubbing bristles extending laterally relative to a surface of the reservoir body, wherein the arm and hand scrubbing bristles have a first stiffness that promotes gentle cleansing of skin surfaces of a person'"'"'s arms and hands during a cleansing procedure without scratching, gouging, scraping or otherwise damaging the skin;

a plurality of fingernail cleaning bristles having a second stiffness greater than the first stiffness of the arm and hand scrubbing bristles in order to more aggressively scrub dirt, pathogens, or other foreign debris from gaps underneath a person'"'"'s fingernails when the person'"'"'s fingers are moved back and forth relative to the fingernail cleaning bristles;

a two-part structural body interconnecting the arm and hand scrubbing bristles with the reservoir body wherein the arm and hand scrubbing bristles are formed on a first part of the two-part structural body, wherein the fingernail cleaning bristles are formed separately on a second part of the two-part structural body, and wherein the second part is and thereafter attached to the first part of the two-part structural body; and

at least one finger guide surface adjacent to the fingernail cleaning bristles and positioned so as to maintain alignment between a person'"'"'s fingernails and the fingernail cleaning bristles so that tips of the fingernail cleaning bristles enter gaps underneath the person'"'"'s fingernails when the person'"'"'s fingers are moved back and forth relative to the fingernail cleaning bristles during use.

2. A scrub brush as in claim 1, wherein the reservoir body comprises a flexible open cell foam and include an anti-infective composition impregnated therein.

3. A scrub brush as in claim 2, wherein the anti-infective composition comprises at least one antiseptic selected from the group consisting of betaine, chlorhexidine glutamate, iodine, povidone iodine, parachlorometaxylenol, chloroxylenol, triclosan, alcohols, quaternary ammonium compounds, cationic surfactants, anionic surfactants, phenol, polyhexanide, sodium chloride, boric acid, hydrogen peroxide, sodium hypochlorite, and terpenes.

4. A scrub brush as in claim 1, wherein the structural body first part and the arm and hand scrubbing bristles are co-molded as a single continuous polymer body.

5. A scrub brush as in claim 1, wherein the arm and hand scrubbing bristles comprise uniform rows and columns of individual bristles extending laterally from a surface of the structural body first part.

6. A scrub brush as in claim 1, wherein the fingernail cleaning bristles extend laterally from a surface of the structural body second part.

7. A scrub brush as in claim 1, wherein the fingernail cleaning bristles are co-molded with the structural body second part.

8. A scrub brush as in claim 1, wherein the fingernail cleaning bristles are molded from the same polymer as the arm and hand scrubbing bristles and are more stiff and rigid than the arm and hand scrubbing bristles as a result of at least one of having shorter length, thicker diameter, closer spacing, or different surface treatment compared to the arm and hand scrubbing bristles.

9. A scrub brush as in claim 1, wherein the at least one finger guide surface comprises a substantially smooth and rigid surface having minimal friction so as to facilitate slippage of fingers across the finger guide surface in a back and forth motion during a fingernail cleaning process.

10. A scrub brush as in claim 1, wherein the at least one finger guide surface comprises a single guide surface.

11. A scrub brush for cleaning arms, hands, and fingernails, comprising:

a structural body having a main wall and an outer sidewall attached to and extending laterally from the main wall;

a reservoir body adjacent to the structural body comprising an absorbent material, wherein the main wall of the structural body is positioned alongside a first side of reservoir body and the outer sidewall of the structural body is positioned alongside at least a portion of a second side of the reservoir body approximately perpendicular to the first side of the reservoir body;

a plurality of arm and hand scrubbing bristles extending laterally from the main wall of the structural body and away from the first side of the reservoir body, wherein the arm and hand scrubbing bristles have a first stiffness that promotes gentle cleansing of skin surfaces of a person'"'"'s arms and hands during a cleansing procedure without scratching, gouging, scraping or otherwise damaging the skin;

a plurality of fingernail cleaning bristles attached to and extending laterally from a surface of the outer sidewall of the structural body and positioned outwardly relative to the second side of the reservoir body, the fingernail cleaning bristles having a second stiffness greater than the first stiffness of the arm and hand scrubbing bristles in order to more aggressively scrub dirt, pathogens, or other foreign debris from gaps underneath a person'"'"'s fingernails when the person'"'"'s fingers are moved back and forth relative to the fingernail cleaning bristles; and

at least one finger guide surface provided by or extending from a surface of the outer sidewall of the structural body and positioned so as to provide separation between a person'"'"'s fingers and the second side of the reservoir body while maintaining alignment between a person'"'"'s fingernails and the fingernail cleaning bristles so that tips of the fingernail cleaning bristles enter gaps underneath the person'"'"'s fingernails when the person'"'"'s fingers are moved back and forth relative to the fingernail cleaning bristles during use.

12. A scrub brush as in claim 11, wherein the at least one finger guide surface comprises a pair of guide surfaces spaced apart and positioned so as to form a finger guide channel within which the fingernail cleaning bristles are positioned.

13. A scrub brush as in claim 11, further comprising a cleaning composition absorbed within the absorbent material of the reservoir body.

14. A scrub brush for cleaning arms, hands, and fingernails, comprising:

a structural body having a main wall and at least one sidewall attached to and extending laterally from the main wall so as to form an outer perimeter of the structural body;

a reservoir body adjacent to the structural body comprising an absorbent material;

a plurality of arm and hand scrubbing bristles extending from the main wall of the structural body, wherein the arm and hand scrubbing bristles have a first stiffness that promotes gentle cleansing of skin surfaces of a person'"'"'s arms and hands during a cleansing procedure without scratching, gouging, scraping or otherwise damaging the skin;

a plurality of fingernail cleaning bristles extending outwardly from the at least one sidewall and positioned around the outer perimeter of the structural body, the fingernail cleaning bristles having a second stiffness greater than the first stiffness of the arm and hand scrubbing bristles in order to more aggressively scrub dirt, pathogens, or other foreign debris from gaps underneath a person'"'"'s fingernails when the person'"'"'s fingers are moved back and forth relative to the fingernail cleaning bristles; and

at least one finger guide surface provided by or extending from the at least one sidewall of the structural body and positioned so as to maintain alignment between a person'"'"'s fingernails and the fingernail cleaning bristles so that tips of the fingernail cleaning bristles enter gaps underneath the person'"'"'s fingernails when the person'"'"'s fingers are moved back and forth relative to the fingernail cleaning bristles during use.
