Abstract
Abstract A hand-held dispensing applicator comprising a source of fluid, a frangible applicator tip attached to the fluid source, and an absorbent member attached to the frangible applicator tip. When the frangible applicator tip is broken, fluid flows from the source to the absorbent member, whereby the fluid is applied and spread on a surface. Preferably, the frangible applicator tip comprises a support element permanently connected to the fluid source, a relatively rigid tongue element extending outwardly of the support element, and a frangible region there between. Preferably, the tongue element comprises ribs for reinforcing the tongue element to resist unintentional breaking of the frangible region. More preferably, the applicator tip comprises a semi-permeable or non-permeable cover disposed around the frangible region to control the speed and direction of the dispersion of the fluid in the absorbent member. Adaptive embodiments allow the generation of designs applicable to a particular medical purpose.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
167 words
A dispensing applicator comprising a frangible applicator tip, said frangible applicator tip further comprising: (a) an attachment member permanently connected to a hand-held fluid source; (b) a substantially rigid tongue element extending outwardly from said attachment member into a fluid-absorbent member, said fluid-absorbent member comprising a body defining an absorbent applicator member in fluid communication with a fluid conduit; (c) a frangible region between said attachment member and said substantially rigid tongue element, whereby unintentional breaking and separation of said frangible region is prevented by a plurality of reinforcing ribs; wherein said frangible region has side edges and is provided with at least two of said plurality of reinforcing ribs located between said side edges and configured to resist deflection and separation; and said at least two of said plurality of reinforcing ribs each being disposed along a respective one of said side edges; and (d) a first shielding means in said fluid-absorbent member for urging directional fluid transfer to a first closely located external application surface.
Claim 2
Dependent Claim
167 words
A dispensing applicator comprising a frangible applicator tip, said frangible applicator tip further comprising: (a) an attachment member permanently connected to a hand-held fluid source; (b) a substantially rigid tongue element extending outwardly from said attachment member into a fluid-absorbent member, said fluid-absorbent member comprising a body defining an absorbent applicator member in fluid communication with a fluid conduit; (c) a frangible region between said attachment member and said substantially rigid tongue element, whereby unintentional breaking and separation of said frangible region is prevented by a plurality of reinforcing ribs; wherein said frangible region has side edges and is provided with at least two of said plurality of reinforcing ribs located between said side edges and configured to resist deflection and separation; and said at least two of said plurality of reinforcing ribs each being disposed along a respective one of said side edges; and (d) a first shielding means in said fluid-absorbent member for urging directional fluid transfer to a first closely located external application surface.
Claim 3
Dependent Claim
59 words
The dispensing applicator of claim 1 , wherein: said first shielding means includes at least one opening proximate first sides of said frangible region and said substantially rigid tongue element in said fluid-absorbent member, whereby said at least one opening is adapted to receive said fluid transfer from said fluid source proximate said first closely located external application surface.
Claim 4
Dependent Claim
55 words
The dispensing applicator of claim 2 , wherein: said first shielding means includes an outer perimetral edge bounding said at least one opening; and means for flexibly securing said shielding means in said fluid-absorbent member; whereby said means for flexibly securing prohibits unintended displacement of said shielding means during a use of said dispensing applicator.
Claim 5
Dependent Claim
67 words
The dispensing applicator of claim 1 , further comprising: at least a second shielding means in said fluid-absorbent member for urging directional fluid transfer to a closely located second external application surface opposite the first closely located external application surface, whereby said dispensing applicator may be used on a second closely located external application surface following completion of use for said first closely located external application surface.
Claim 6
Dependent Claim
54 words
The dispensing applicator of claim 4 , wherein: the second shielding means includes at least a second opening proximate first sides of said frangible region and said tongue element in said fluid-absorbent member, whereby said at least second opening is adapted to receive said fluid transfer from said fluid source proximate said second surface.
Claim 7
Dependent Claim
63 words
The dispensing applicator of claim 5 , wherein said second shielding means further includes: (a) a second outer perimetral edge bounding said at least second opening; and (b) second means for flexibly securing said second shielding means in said fluid-absorbent member; whereby said second means for flexibly securing prohibits unintended displacement of said second shielding means during a use of said dispensing applicator.
