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 therebetween. Preferably, the tongue element comprises ribs for reinforcing the tongue element to resist unintentional breaking of the frangible region, and 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.
