Abstract
Abstract Apparatus for the oral application of medicinal compositions, fluorine compounds, dentifrice and the like includes a handle to which a spongy block of porous material is removably, but tenaciously, secured by a plurality of small, hooklike members carried by said handle and interengageable with and into reticulations on a surface of said block. The applicator is particularly useful in applying fluorides in viscous gellike form to the teeth.

Total Claims: 2
Claim 1
Independent Claim
180 words
An oral applicator, comprising: an elongate handle member having a proximate end adapted to be manually grasped and a distal end introducible into the mouth; a right rectangular spongy block of reticulated polyurethane foam material having at least one exposed reticulated surface; said distal end of the handle member having a broad flat surface provided with a pile patch, substantially coextensive with said reticulated surface, comprising a multitude of small, flexible hook members outstanding thereon, said hook members being randomly arranged in said patch and interengageable with reticulations in said block at said surface when said block and said reticulated surface are pressed together; the interengagement of said hook members with said spongy block surface being such that when said spongy body is mounted on said handle to form an assembled applicator, said members will tenaciously grip said block in such manner as to withstand sheer forces normally encountered in oral therapeutic applications, but also in such manner that said block may be easily peeled from said handle by a lifting force initially applied at the end of said block.
